The solid tire improves the heat generation function of the tire, so that the heat generation of the tire is greatly reduced. The solid tire and the rim are press-fitted together through an interference fit. The excessive heat generation of the carcass will cause the tire slip ring to expand.Ordinary tires and all-season tires are wear-resistant, but in winter, especially below zero degrees Celsius, the traction of the tires will be relatively reduced, and there will be slippage in the face of icy and snowy roads. The rubber composition is higher and not wear-resistant.Solid tires have the advantages of good rigidity, high hardness, good stiffness, small deformation, small expansion coefficient, and low heat generation, so the slip ring phenomenon caused by the expansion of the hub caused by the heat generation of the tire is basically eliminated. A tire anti-skid ring is a tire anti-skid device provided for cars driving on ice and snow roads.It utilizes the protruding tufts of the tread and the circular dimples on the tread, which greatly improves the grip between the tire and the ground, and has the characteristics of good anti-skid effect, no damage to the road surface, convenient installation and use, low cost and simple structure.In addition to more protection work in vehicle design and configuration, careful operation is the key to preventing slippage when encountering special road conditions. Solid tires on slippery roads should be controlled more gently, always alert to possible accidents and emergencies ahead. When driving on the road in the rain, your shoes can get wet and easily slip off the pedals when you step on them. The soles of the shoes should be dried on the car carpet before starting the engine, and all car drivers should regularly check that the headlights, taillights, brake lights, and turn signals are in normal condition.

The solid tire is a kind of tire corresponding to the pneumatic tire (hollow tire). The earliest tires are solid tires. Solid tires are currently only used for high-load vehicles or machinery that travel at low speeds, and are also used for fixed-position machinery.Solid tires are generally divided into two types: bonded and non-bonded. The former refers to tires whose rubber is directly vulcanized on the rim, and the latter refers to 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.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 superior to pneumatic tires, and are widely used in various industrial vehicles, military vehicles, construction machinery. , towed vehicles in ports and airports, etc.

Is the performance of solid tires affected by temperature?In fact, the influence of the outside air temperature on the working temperature in the tire is very small, because when the vehicle is running normally, the air temperature inside the tire will increase significantly, and the influence is much greater than that of the outside temperature.If your car is equipped with tire pressure monitoring, you might as well verify it yourself. Next time you drive, pay attention to observe the changes in tire pressure. You will find that even on a hot day, from a cold car to driving for a long time, the tire pressure is very high. There will be no particularly noticeable changes.There are also studies that show that when the tire temperature changes by 50 degrees Celsius, the tire pressure change is only 0.5bar, while the safe tire pressure value of our car is generally 2.2bar-2.8bar, so as long as we follow the standard tires on the door frame Pressure to operate, a change of 0.5bar will not let it exceed the safe value at all.The temperature of the tire will increase after a period of driving, and the temperature of the tire is higher than the ambient temperature, so the influence of the ambient temperature on the tire pressure can be ignored. That is to say, the tire pressure in the hot tire state will not be affected by the seasonal ambient temperature. That is, the tire pressure in the working state will not be affected by the seasonal ambient temperature.However, it should be noted that the problem of tire temperature is undoubtedly a fatal weakness for long-distance bus drivers and large truck drivers. Long-distance driving will accelerate the wear of tires, and excessive temperature will accelerate the aging of tire rubber and the softening of steel wires. Overheating will be directly fed back to the tread surface, which is the pattern. The pattern will speed up the wear, but a good tire has a strong ability to dissipate heat. Therefore, when the temperature is high, the quality of the tire rubber can be tested, and the material of the pattern is the tire rubber.

A solid tire is a tire corresponding to a pneumatic tire (hollow tire). Its substance is solid. It doesn't need a rope as a skeleton, and it doesn't need inflation. Solid tires do not pose a danger to tire bursting. Next, Zhejiang Kunrong Rubber Technology Co., Ltd will introduce the characteristics of solid tires in detail.1. Excellent safety performance is conducive to improving work efficiency. Since the solid tire matrix is composed of all rubber, the penetration resistance of the tire is guaranteed to the greatest extent, and the tire penetration during loading and running of industrial vehicles and in harsh working environments is guaranteed. hazard. The load deformation of solid tires is fundamentally eliminated, and the running stability is good. Because of its puncture resistance, tear resistance, and no need to inflate, it avoids the heavy labor of frequent tire repair and tire replacement, and improves the use efficiency and work efficiency of the vehicle. Solid tires can replace pneumatic tires on low-speed, high-efficiency vehicles.2. Reasonable structural design ensures better performance of tires. Effective solid tires adopt advanced tertiary structure design, three composite materials to ensure the overall performance of tires, high rigidity, high strength base rubber and steel ring support, It not only ensures the rigidity of the tire, but also ensures the tightness of the tire. The rim fundamentally eliminates the slip ring problem of solid tires; the high elastic intermediate rubber effectively absorbs the vibration generated when the vehicle is running, has a comfortable driving performance, and avoids damage to the vehicle; the thicker the tread rubber layer, the better the tire. The more secure it is; tear and abrasion resistance improves performance. CE life of solid tires.3. Advanced technology and formula design. The production of high-efficiency solid tires adopts the advanced technology of British industrial tire manufacturers. With more than half a century of production history and experience, the rubber formula design maximizes the performance of tires. In particular, the rubber base materials are imported from abroad and have high rigidity and low calorific value composite materials. The heat generation and temperature rise of the tire during operation are the lowest, and the heat resistance of the tire is improved at the same time, which can solve the serious problems of solid tire expansion, slip ring, and burst caused by the temperature rise. The advanced formula design reduces the rolling resistance of the tire.4. In solving the advantages of tire slip rings, falling blocks, cracks, etc., imported fiber rubber is used as the tire base material, which improves the heat generation performance of the tire and greatly reduces the heat generation of the driving tire. The rims are pressed together to cause the tire slip ring to expand due to the overheating of the matrix. The fiber glue has the advantages of good rigidity, high hardness, good rigidity, small deformation, small expansion coefficient and low heat generation, which fundamentally eliminates the heat generated by the tire. The slip ring phenomenon caused by the expansion of the hub.5. The impact of structural changes on tire performance, by widening the tire section of the snap-in structure, the stability of vehicle operation is enhanced.

Tires play a very important role in various parts of automobiles, and have a great impact on various driving performances of automobiles. The use of polyurethane tires is becoming more and more popular. Today, Zhejiang Kunrong Rubber Technology Co., Ltd will introduce to you why polyurethane tires are called green tires. Rubber tires are exposed to short service life, poor wear resistance and tear strength during use, especially truck tires, which often lead to tire blowouts due to their limited load capacity.In order to make up for the shortcomings of rubber tires, polyurethane tires are produced. The reason why polyurethane tires can make up for the shortcomings of rubber tires is that polyurethane elastomers are ideal materials for green tires.In terms of its Young's modulus, polyurethane elastomer is a polymer composite material with high hardness of plastic and high elasticity of rubber, mainly including polyurethane compound rubber, polyurethane casting rubber, polyurethane water latex and polyurethane heat. plastic. Compared with rubber, polyurethane elastomers have superior wear resistance, higher tear strength and elongation and a wide range of hardness. In particular, the cast polyurethane elastomer is the most wear-resistant elastomer at present. It has the advantages of high wear resistance, colorability, high cutting resistance, excellent oil resistance and chemical resistance, and is non-toxic to the human body. It is not necessary to add carbon black, so polyurethane is an ideal material for making tire treads.In addition, polyurethane tires have good vibration absorption and shock absorption effects, very large load capacity, and extremely ideal resistance to oil and other chemicals. Because polyurethane elastomers have special physical and mechanical properties that other polymers do not have, they are widely used in many aspects such as national defense, light textiles, transportation, oil fields, mining, machinery, construction, and medical care.

How to choose the right type of forklift tire? The following are some suggestions of Zhejiang Kunrong Rubber Technology Co., Ltd: The forklift tire factory recommends that you choose suitable forklift tires for the working conditions and environment.You can choose the appropriate tire type according to different working conditions and use environments;1) For example, when working outdoors, the road conditions are good, and the working distance is long (500 meters or more), it is recommended that you choose pneumatic tires. Although solid tires can basically avoid the safety hazards caused by pneumatic tire blowouts, it is difficult to withstand long distances. Internal heat generation from distance, uninterrupted operation;2) In more cases, it is recommended to use solid tires. In addition to the need for air pressure maintenance of pneumatic tires, solid tires do not have the safety hazard caused by puncture of pneumatic tires. Good solid tires are cost-effective and maintenance-free. It is much better than pneumatic tires in many aspects, such as longer replacement cycle; under the working conditions of moderate working strength, distance and load, solid tires with side holes with higher shock absorption effect are better considering safety and safety. A good choice for comfort;3) For forklifts that carry out handling operations in a clean room, it is recommended that you choose light-colored solid tires without imprints, which can greatly reduce the obvious black marks left on the ground by the forklift during load transportation, especially when turning, emergency stop and emergency braking;4) In the working environment with hazardous chemicals or the risk of dust explosion, it is extremely important to choose run-flat tires with special formulations. The static electricity generated when the vehicle is running can be directed to the ground in time to avoid potential safety hazards caused by the accumulation of static electricity. When choosing run-flat tires, Shandong Forklift Tire Factory recommends that you select and assemble under the guidance of professionals.

Generally, when purchasing a solid tire rim, the first thing to look at is its related parameters. The parameters of the rim mainly include: diameter, width, PCD and hole position, offset distance, and central hole 5 factors:1. Diameter: The size design of the steel ring is actually to adjust the diameter of the steel ring. We can often hear the Chinese people say 15-inch steel ring and 16-inch steel ring technology. Among them, 15 and 16 inches refer to is the size (diameter) of the steel ring. Large rims and tires provide good visual tension and increase vehicle stability, but have other problems with increased fuel consumption.2. The width of the rim is what we commonly call the J value. The width of the rim will directly affect the choice of tire. For tires of the same size, the J value is different, and the aspect ratio and width of the selected tires are also different.3. The professional name of PCD is pitch diameter, which refers to the diameter between the fixing bolts in the center of the rim. Taking 5*113 as an example, it means that the PCD of this rim in China is 113mm, and there are 5 bolts in the hole.4. Bias: English is Offit, commonly known as ET value, the edge distance between the installation surface and the center line, this parameter can usually be found on the back of the edge.The ET value is positive for general vehicle management and negative for a few corporate vehicles and some jeeps.5. The big hole is in the middle of the rim. Note that the size of the center hole is the correct data measured from the back.The central hole is used to connect the fixed network with the vehicle, which is due to the position of the rim concentric with the rim through the center.6. You can directly tell the tire manufacturer the size of the tire you use. If you don't know how to measure it, we will have a special technician to measure it to ensure that you use the appropriate rim.

Zhejiang Kunrong Rubber Technology Co., Ltd. will talk about the installation precautions of solid tires. Pneumatic tire rims solid tires and corresponding pneumatic tire rims can be used interchangeably. However, the loading and unloading of solid tire rims can only be completed with auxiliary tools (tools) on the press. In order to ensure the safety and accuracy of the installation process, the following rules should be followed:1. Inspection of tires and rimsFirst, check the compatibility of the tire and the rim, that is, whether the specification and model of the tire to be installed are the same as the rim model. The rim width used by tires of the same specification is different, please confirm first when installing. The inspection of the rim includes whether the rim is defective and whether there are burrs. If there is any burr, it should be smoothed first, otherwise it is easy to damage the inside of the tire hub, which will affect the installation and use.2. In order to ensure that the tire can be smoothly installed in place and reduce the friction between the tire and the rim, during installation, the inner surface of the tire hub and the outer surface of the rim should be sprayed and coated with lubricant. The lubricant can be selected from commonly used soapy water, washing powder water, etc. Conditional lubricants for tires can be used, but greases and other common industrial lubricants must not be used, because they will swell the rubber and damage the tires.3. When the tire is placed on the rim, the head should be flat and should not be deflected, otherwise it will be difficult to install, and it will sway from side to side during use. The rim must be installed in place and the bolts must be tightened, otherwise the slip ring or the separation of the tire and rim will cause danger.4. According to the requirements of the ETRTOEDI standard, the tires must be concentric when they are installed on the vehicle. Tires of different specifications and different wear and tear cannot be installed on the same vehicle or on the same axle, and cannot be mixed with pneumatic tires, otherwise it is easy to cause personal and equipment accidents.

1. Excellent safety performance, which is conducive to improving work efficiencyBecause the solid tire carcass is made of all rubber, the puncture resistance of the tire is guaranteed to the greatest extent, and the hidden danger of tire puncture in the process of load-bearing operation of industrial vehicles and in harsh working environments is fundamentally eliminated. Solid tires have small load-deformation variables and good running stability. Because of their puncture resistance and tear resistance, they do not need to be inflated, which avoids the heavy labor of frequent tire repair and tire replacement, and can improve the utilization rate and work efficiency of the vehicle. In vehicles, solid tires can completely replace pneumatic tires.2. Reasonable structural design to ensure that the tire has good performanceThe solid tire adopts an advanced three-stage structure design, and the three kinds of rubber compounds ensure the overall performance of the tire. The high-rigidity, 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 problem of the sliding ring of the solid tire; the high-elasticity intermediate rubber effectively It absorbs the vibration generated when the vehicle is running, has a comfortable driving experience, and avoids damage to the vehicle at the same time; the thick tread rubber layer ensures the tear resistance and wear resistance of the tire and improves the service life of the solid tire.3. Advanced technology and formula designThe production of solid tires has advanced technology with more than half a century of production history and experience, which maximizes the performance of tires in the design of rubber formulations. The heat generation and temperature rise and fall during operation are minimized, and the heat resistance of the tire is improved at the same time, thus solving the serious problems such as swelling, slip ring, and burst caused by the temperature rise of the solid tire.The advanced formula design reduces the rolling resistance of the tire. Tested by the National Construction Machinery Quality Supervision and Inspection Center, the rolling resistance coefficient of solid tires is equivalent to that of pneumatic tires, which solves the problem of increased fuel consumption caused by the replacement of solid tires.4. Avoid the danger of vehicle tire burst out of controlPneumatic rim-type solid tires are solid tires that can be used interchangeably with pneumatic tires of the same specification. When the vehicle is running at high speed, if the tire hits potholes and other obstacles, the tire will be severely squeezed and deformed between the obstacle and the rim flange, which can cause the carcass cord to break, and the compressed air inside the tire will be broken. The line is jacked up to form a bulge.If it is more serious, it will cause the tire to crash and rupture, and it will be completely deflated in an instant, and there may be a danger of losing control of the vehicle. Compared with pneumatic tires, it has the advantages of high safety, puncture resistance, tear resistance, wear resistance and long life. It is an ideal replacement product for pneumatic tires in the field of industrial vehicles. With the development of industrial vehicles and the improvement of solid tire production technology, this kind of tire is more and more widely used.
