Everyone is saying that you should regularly check the tires, tire pressure, tire temperature, air leakage, etc., and try to avoid tire blowouts. Then someone asked: Don't you need to worry about these if you make it directly? Now let's talk about why the tires don't need to be solid.1. Features of solid tiresThe biggest advantage of solid tires is that they are wear-resistant, so you don't have to worry about tire pressure and air leakage. Another point is that solid tires can carry more load than pneumatic tires. Finally, in terms of the aging speed of rubber, solid tires must last longer than radial tires, which can meet the long-term use needs of vehicles working in harsh environments.2. Reasons why solid tires are rareBut why did radial tires replace solid tires? The previous rubber tires were indeed solid, but they were not comfortable in use. As the saying goes, a shoe weighs one kilogram and a person weighs five kilograms. The same is true for tires. Solid tires are definitely heavier than the current radial tires, which will cost more. Oil. Furthermore, the solid tires are not comfortable enough, the bumps during driving are more intense, and the cost is higher.3. UnstableWhen the tire is running at high speed, it is too late to restore the deformation, and it is possible to generate a standing wave on the carcass, which will cause the tire temperature to rise sharply and cause the tire to burst. Solid tires are more prone to this phenomenon, and there have been cases of tire chipping in tests using solid tires.In addition, the solid tire increases the unsprung mass. The larger the suspension mass, the slower the suspension system responds to changes in the road surface, which has a great impact on the dynamic performance of the vehicle.4. Application of solid tiresIn fact, solid tires have not completely disappeared. For example, the tires of some forklifts and other models, the lift wheels on the plane use solid tires.

Nowadays, there are many kinds of car tires. The most widely used one is pneumatic tires. In fact, there are many kinds of tires besides pneumatic tires. Solid tires are one of them. Maybe people rarely see solid tires, but they are all around us. Today, Zhejiang Kunrong Rubber Technology Co., Ltd will introduce you to solid tires.Introduction to solid tiresSolid tire is an industrial tire suitable for low-speed, high-load running vehicles. In addition to the characteristics of pneumatic tires, it also has the advantages of low starting resistance, simple structure, convenient use and maintenance, small maintenance workload, no need for inflation, no Air leaks and punctures. Therefore, the safety, durability, puncture resistance, tear resistance and economy of solid tires are better.Application of solid tiresSolid tires are mainly used for industrial vehicles such as low-speed and high-load hoisting vehicles, traction vehicles and flatbed trucks, such as various forklifts, port and airport trailers, etc. Military, construction machinery and other fields, but also widely used in medicine, food, paper, textile, electronics and other fields.1. Pneumatic tire rim solid tireSolid tires mounted on rims for pneumatic tires.2. Steel rim press-fit solid tireTires that are vulcanized on endless metal belts and then pressed onto matching wheels.3. Bonded solid tireTires vulcanized directly on the running wheel.4. Solid tire without imprint (green tire)Solid tires that do not leave marks on the ground, especially brake marks, during use.

Solid tires and corresponding tire rims are interchangeable and used during inflation. However, the loading and unloading of solid tire rims needs to be completed with auxiliary teaching tools (tools) on the working press. In order to ensure the safety and accuracy of the system installation process, the following rules should be followed:1. Choose the right tire pressAt present, the commonly used tire presses in my country are 120 tons, 200 tons, 250 tons, 300 tons, 350 tons, etc. A suitable tire press should be selected according to the students' own needs.2. Inspection of tires and rimsCheck the fit of the tire and the rim, the same size tire, the width of the rim is different. Please confirm when installing. The inspection of the rim mainly includes whether the rim is defective and whether there is burr. If there are burrs, it needs to be smoothed, otherwise the hub will be easily damaged, which will affect the installation and use.3. In order to ensure the smooth installation of Chinese tires and reduce friction with the rim, during installation, the inside of the tire's hub and the outer surface of the rim should be sprayed and coated with lubricant. The lubricant can be selected from some commonly used soapy water, Washing powder, water, etc., can be used as a special mechanical lubricant for tire companies if conditions permit, but not necessarily lubricating oils commonly used in industrial technologies such as greases, etc., because they will swell rubber and damage tires.4. When the tire is placed on the rim, its head should be flat and should not be skewed, otherwise it will be difficult to install and swing left and right during use. The rim must be in place and the bolts must be tightened, otherwise there is a danger of slipping easily or separating the rim.5. According to the standard requirements, when the tires are loaded, the same axles must be used with the same specifications of the same manufacturer, and cannot be mixed with pneumatic tires.

Today, let's explain the development of forklift solid tires in detail:Economical; deep tread pattern design greatly improves tire usage and prolongs usage time. It will not break the tire, avoid the waste of tire repair fee and puncture, and save the cost.Safety: Good high temperature resistance and low heat generation make the tires still have good safety in harsh environments. Low compression deformation, high recovery characteristics, the tire still maintains good operating performance under high load conditions. It is composed of low heat generation and cutting-resistant materials, and it still has better load capacity under long-distance and long-term construction.In addition, the inside of the carcass is completely filled with elastic colloid, no matter where it is used, there is no tire breakage or puncture. And there are equal and the same colloidal coordination, which can completely avoid the above situation, and can effectively increase the safety requirements no matter what the operation is.The solid tire adopts the front three-stage structure design, and the three kinds of rubber materials respectively ensure the overall performance of the tire. The high-rigidity and high-strength base rubber and steel ring support not only ensure the stiffness of the tire, but also ensure the tightness of the tire and the rim, which fundamentally eliminates the sliding ring problem of solid tires.Timeliness: Forklift solid tires have higher load performance, which can reduce the cross-sectional area of the tire and the contact surface, greatly reduce tire wear, increase vehicle flexibility, and improve work efficiency. The characteristic of not breaking the tire can avoid the idle time wasted by vehicles and personnel when the tire is broken or repairing the tire, and increase the working energy.

Solid tire tread is punctured by sharp objects and nails. The main reasons for the impact on the tire are: When driving on a road with poor road conditions, the tire may hit deep pits or other foreign objects, causing the tire to be severely squeezed and deformed between the impact object and the rim flange, causing the sidewall cord to break, and the air inside the tire will A bulge will be formed from the broken yarn. In addition, it is also possible that the tires scratch against obstacles when hitting the road and parking, which may also cause damage to the sidewall and appear "bulging". Although there is a bulge, it will not affect the driving of the car.Solid tires also have many advantages. The biggest advantage of solid tires is that they have strong bearing capacity and will not puncture. Therefore, it is still very useful in some special places such as engineering vehicles, construction sites, forestry, metallurgy, airports, ports, etc. It is not afraid of overloading, puncturing, and scalding. Use in these special places can improve the safety of vehicles. Of course, the speed of cars in these places is very low.

Due to its own advantages, solid tires are often used as load-bearing tires. Compared with general inner tube pneumatic tires, steel radial tires, semi-steel radial tires, bias tires, etc., they have the following advantages:1. Use high-quality natural rubber with stronger performance.2. It is composed of hard base rubber, high elastic core rubber, and super wear-resistant tread with three layers of plastic particles, which is more durable.3. The load capacity is stronger, and there is no need to worry about puncture, tire blowout, etc., and maintenance-free.

Do you know the repair tips for forklift solid tires that are degummed or broken?1. Hot patching: File the roughness around the damaged inner tube, stick the fire patch on the damaged area, and make the hole just in the patch, then install the patch clip against the normalizing patch, and tighten it. Press the screw and then ignite the heating agent on the fire repair glue, and wait for 10-15 minutes to bond tightly. 2. When the inner tube is found to have small holes, it can be hot or cold. 3. Outer tire: If the outer tire has cracks, holes, blistering, delamination and other damages, it should be repaired or overhauled according to the specific situation. If there are continuous cracks around the tire carcass, the tread rubber has been polished and there are large holes, the carcass line layer has annular cracks and the whole circle is separated, it should be replaced. 4. Raw rubber patching (cold patching): file rough around the inner tube break, apply raw glue, and then apply secondary glue after the surface of the glue is slightly dry. When the glue is air-dried, attach the prepared raw rubber to the broken On the mouth, pressurize and heat at 140-145 ° C, keep warm for 10-20 minutes to vulcanize the raw rubber, and after cooling, it can be tightly bonded.

There are not a few traffic accidents caused by car punctures, especially in high-speed sports cars, the survival rate of accidents caused by punctures is low. Then, some people will ask, since a flat tire is so dangerous, it would be better to make a solid one, and there will be no such thing as a flat tire. Is it really the truth? Our car tires are made of rubber, and the operation is to use the elasticity of the rubber carcass to reduce the impact generated when the wheel turns. If the tires are replaced with solid ones, the cushioning capacity will be greatly reduced, and it is not suitable for high-speed transportation vehicles. And solid tires will damage the road surface and consume much more energy than today's pneumatic tires. Solid tires have no air leakage, and even if the vehicle is overloaded, it will not deform, and it seems to be very simple to use and maintain. Even if applicable, it can only be used for low-speed high-load vehicles, such as industrial loading and unloading vehicles and power vehicles for cargo purposes. The role of tires for vehicles is shock absorption, grip, stability, load-bearing, etc., which can be said to be a very important component. Let's talk about the role of pneumatic tires from the perspective of shock absorption. Pneumatic tires can achieve the effect of shock absorption by generating deformation during operation. To talk about grip and handling, the grooves on the tires have drainage lines, which can prevent the car from slipping, but if the tires are replaced with solid ones, not to mention the waste of materials, various performances will also be greatly reduced. In general, solid tires have many disadvantages, except that they can save the need to check the tire pressure frequently and do not need to be frequently inflated. Therefore, solid tires are not practical, so don't be afraid to use pneumatic tires.

The carcass of a solid tire is solid. No rope is used as a skeleton, no inflation is required, so no inner tube or seal is required. The early tire company was a solid tire. Solid tires are generally used under high loads, which requires the compound to have sufficient pressure resistance and wear resistance, high modulus stress, high hardness, low deformation, and good wear resistance. Solid tire is an industrial tire suitable for running and managing vehicles under different conditions of low speed and high load. Its safety, durability and economy are obviously better than pneumatic tires. It can be widely used in various electronic industries Social vehicles, military vehicles, construction machinery, towed vehicles in ports and airports, etc. Solid tires often need to be transported during production. Due to the heavy weight of the solid tires used in large vehicles, they cannot be transported manually at all. Therefore, in general, mechanical operations are used. In order to prevent tire surface damage, hooks or chains cannot be used for loading and unloading. At present, many factories use forklifts for loading and unloading, which has low loading and unloading efficiency and high cost. The handling technology of solid tires is used to assist the construction of teaching facilities for classification and handling. The operating system buttons and operating gear levers in the box can be controlled as described above to control the research machine to move to the designated position, and then the turntable rotates and the said control problem according to the control problem. The length adjustment motor starts and develops to drive the front and rear of the cross bar. The application of China Mobile makes the company's fixed plate reach the top of the tire that the company needs to improve handling. Adjust the length of the piston rod of the cylinder through the market to adjust the position of the suction cup to reach the tire. Above the smooth surface of the tread, the hydraulic support rod shrinks so that the suction cup is lowered and adsorbed on the surface of the tire, and then the hydraulic support rod extends to suck up the tire and place it in a designated place.

The solid tire is a kind of tire corresponding to the pneumatic tire (hollow tire). The earliest tires were solid tires. Solid tires are currently only used for high-load vehicles or machinery that travel at low speeds, and also for machinery in fixed positions. Chinese name Solid tire Foreign name Solid tire Suitable for low-speed high-load vehicles or machinery Classification Bonded and non-bonded features High elasticity, strong heat dissipation, good wear resistance Production of raw materials Precautions for the use and installation of solid tires ▪ Installation of solid tires ▪ Load speed requirements of solid tires ▪ Tire replacement ▪ Storage and maintenance of tires Classification of solid tires Solid tires are generally divided into two types: bonded and non-bonded. The latter refers to the tires that are vulcanized and then fixed on the rim. According to the shape, it is divided into cylindrical solid tire and inclined bottom solid tire; according to the application, it is divided into antistatic, conductive, oil-resistant, high-load solid tire, and environmentally friendly non-marking solid tire. Heavy load v has a strong bearing capacity, suitable for harsh environments, high safety and high elasticity. Mainly used in DUMP TRUCK v Main specifications: 825-20, 900-20, 1000-20, 1100-20 for dock trailers v low rolling resistance, low heat generation, super high bearing capacity, mainly used in dock low flatbed vehicles v main Specifications: 22x8x16, 22x9x16, 22x14x15, 22x16x16 boarding bridge for all-weather use, suitable for various weather conditions, flexible and long service life. Solid tire is a special kind of tire, mainly suitable for special vehicles such as anti-riot vehicles, cash transport vehicles, anti-terrorism vehicles, engineering vehicles, forestry machinery and so on. Solid tires are generally used under high load, and the rubber compound is required to have sufficient pressure resistance and wear resistance, high enough tensile stress, high hardness, low permanent deformation and good wear resistance. Solid tire is an industrial tire suitable for running vehicles under low-speed and high-load harsh conditions. Its safety, durability and economy are obviously better than pneumatic tires. It is widely used in various industrial vehicles, military vehicles, construction machinery. , towed vehicles in ports and airports, etc. The main raw materials for solid tires are made of a special rubber material. Except for a few hollows in the middle to maintain the center of gravity, all of them are solid. The tires made in this way can be anti-stud, bullet-proof, mine-proof, and incendiary-proof... They are very popular among police officers. But solid tires are very bulky, and the handling is not very good after being installed on the car, so it needs to be further improved by professionals. Solid tires can be divided into non-marking environmental protection type, conductive type, optional type, standard type, oil-resistant type and high-load type according to their use. A. Non-marking environmentally friendly tires: generally light colors, such as white, gray, green, yellow, etc. It is almost close to the ground color of special industries, leaving no or less tire marks during use, keeping the ground clean and tidy.

Forklift tires cannot completely ensure that the properties of the tires do not change within a certain period of time after leaving the factory and before the actual installation and application, that is, due to the process of transportation and transportation and possible development, there will be collisions, rubbing, and even some special social conditions. The influencing factor after the material touches is also the wear and tear of the tire's service life. Therefore, we need to analyze the forklift solid tire model when it leaves the factory. The packaging of different research methods, let's take a look at it now: At present, the packaging of tires is usually done by wrapping strips, that is, manually or automatically wrapping a narrow rectangular cover layer and wrapping it along the circular structure of the tire. The packaging design method uses polyester film as the main base material, which has good elastic tension. The surface of the product is coated with a moisture-proof engineering plastic surface, which can resist moisture and moisture. The film is smooth and soft, which can effectively prevent tire surface scratches. However, this approach also has some drawbacks. Since the packaging structure is cyclic winding, repeated packaging, and overlapping packaging strips, material consumption and packaging costs are relatively high. Moreover, the packaging is inconvenient, and it is inconvenient to improve work efficiency. It also takes a certain amount of time to remove the packing tape. Moreover, the damaged packaging tape is inconvenient to recycle, causing white pollution; however, the wrapping effect of the packaging tape is not ideal, and the tires are easily damaged during transportation. In order to improve the performance of the product packaging layer, we can choose to use plastic film, aluminum foil for composite material film, polyester film, etc. through the base tape, add strip-shaped tape, or can be stacked into a tape roll. The film can be made of ordinary pressure sensitive adhesive or double-sided film. It is adhered to the inner edge of the base tape. It can be adhered to the edge by one side, or it can be divided into two urban edges. When applied, wrap the packaging tape, and continuously press the film on the outside of the base tape of the packaging tape wound on the tire to form a continuous overall package. The sealing effect is good, it is not easy to leak water and dust, which prevents the pollution of the tires from the outside of the enterprise, and also overcomes the shortcomings of the current green packaging belts that are easy to dislocate and expose the tires.

The characteristics of forklift solid tires are good wear resistance, 3-4 times the service life of ordinary pneumatic tires, and no tire breakage (unless tire quality problems). Solid tires for forklifts are durable and pressure-resistant. Pneumatic tires will puncture, and the deformation will be relatively large when the load is loaded. You lift a pallet of goods and prepare to put them on the shelf. At this time, the tire punctures or the tire is deformed, and the goods will fall to death. Today Zhejiang Kunrong Rubber Technology Co., Ltd. What I share with you is how to identify the retreading of forklift tires, and learn quickly! The method of identifying retreaded tires is very simple: it is more common to observe the color and luster of the tires. The color and luster of the retreaded tires are relatively dim, so do not blindly buy such tires. The correct method is to identify the tires by the signs on the tires. There are some raised signs on the car tires, indicating the type and performance of the tires. These are the breakthrough points for identifying retreaded tires. The signs of retreaded tires are re-applied after retreading, while these signs of brand-new tires are integrated with the tire. The identification method is to scratch these signs with fingernails. Generally, these signs of retreaded tires are not very tight. , the one that can be caught must be the retreaded tire. Check whether the repairing process of the tire is fine. If there are bright slag, floating rubber threads and scorch, it means that the tire has been retreaded.
