What is the reason for the peeling phenomenon of environmentally friendly solid tires in summer?

Solid tires are tires with excellent wear resistance and less heat generation composed of four parts: ply, bead, buffer layer, and tread. Due to the high temperature in summer, the temperature of the road surface is also very high under long-term exposure to the sun, and when solid tires are driven on such a high-temperature road surface, it is found that sometimes the tires that have not been used for a long time have peeled off. Today Let's follow Zhejiang Kunrong Rubber Technology Co., Ltd. Learn more about this issue. The peeling of solid tires is sometimes related to the selection and installation of tires. Whether the solid tire installation is directly related to the service life of the tire, especially when replacing tires, tires with different types and patterns, because the actual size and fit of each solid tire are different, so it must not be arbitrarily mixed. . At the same time, the tire pressure of solid tires must also be adjusted well. Too high or too low tire pressure is unscientific, which will affect the service life of solid tires. If the tire pressure is too low, its radial deformation will increase, the sides of the tire wall will be deformed excessively, and the wear of the crown and shoulders will occur, which will increase the temperature of the tire and seriously reduce the service life of the tire. In addition to the tire pressure of solid tires, the cleaning of solid tires is also very important. Before or after driving, check whether there are hard objects such as stones, iron blocks or nails in the tire grooves. If there are, clean them immediately. Solid tires are now widely used in various fields. At the same time, we do not recommend that tires be stored in wet places. If environmental conditions cannot be prevented, we also recommend proper maintenance of tires to extend the use of tires.

Should the debris in solid tires be cleaned regularly?

Due to long-term contact with the road, solid tires will inevitably embed stones in the tire markings, not only the texture is messy, but also the stones in the markings will hit the ground when driving, making a knocking sound. For us, does this crushed stone embedded in the tire texture need to be sorted? What's the harm in it? ①Affecting noise: Because the sound of the tires is relatively small when the company is running normally, and because the rubber tread in our country is relatively soft, but we will not have the same after embedding stones. And the gravel in the stripes will roll with the tires and hit the ground hard, as if someone was slammed into the ground and clashed, the rapid clattering sound is almost maddening. ② Prevent urban drainage: If the Chinese tire markings can act as a water guide when driving in rainy days, it can ensure that the tires can quickly shake off the liquid on the tires when driving through the water, and ensure that the grip of the tires in my country is not strong. There will be a drop to too much. If too much gravel is embedded in the Chinese tire pattern, it will significantly reduce the level and the drainage of the tire, causing the Chinese tire to skid. ③Danger of puncture: Although the tire tread has a solid comparison and research, it is usually difficult to directly pierce the stones that can be embedded in the markings, but if you drive too much at night, you will hit ghosts, and if you drive too much, we will inevitably embed sharp and strong stones The stone culture and even Chinese metal blocks, it is also possible for the enterprise to pierce the tire wall at this time. On the other hand, when the car is running at high speed, the high-speed conflict will cause the tire temperature to rise, the air in the tire to expand, and the tire wall thickness to become thinner. If there are some sharp stones embedded in the markings, it is easy to blow the tire at this time. In addition, the gravel in the tire pattern has to go through the double kneading and conflict between the sidewall and the ground, and some exposed outside the tread will soon be ground flat. And in the process of grinding, if the Chinese car market travels at a high speed, the gravel will easily sputter out in time, and the impact force is not small, which will damage your own car or other vehicles driving beside it.

How to deal with tire wear?

During the long-term use of solid tires, there may be wear and tear, so how to solve the wear and tear? Zhejiang Kunrong Rubber Technology Co., Ltd.'s measures to solve tire wear are as follows: 1. Cracks in the tire casing and perforated foam should be replaced if there are continuous cracks around the carcass, or when the tread rubber has been polished and there are large holes, and the carcass line layer has annular cracks and separation. 2. When the inner tube has small holes, it can be hot or cold. After roughening the damaged area of the inner tube, stick the fire repair glue on the damage, so that the holes can be in the center of the repair glue, then install the tire repair clip against the normalizing repair glue, and tighten the screw of the machine to tighten it again. Ignite the fire to make up the glue, wait for 10-15min, and then it can be bonded. 3. If the inner tube is stretched, severely cracked, brittle, sticky, or deformed, it cannot be corrected and must be replaced immediately.

What are the types of solid tire patterns?

The main function of the solid tire pattern is to prevent the wheel from slipping by increasing the friction between the tread and the road surface. The patterning of the tire not only improves the elasticity of the tread grounding system, but also under the action of the driving force, braking force and lateral force between the tread and the road surface, the pattern block can produce significant tangential elastic structural deformation. There are mainly the following categories: 1. Straight groove pattern: This traditional pattern has excellent operation stability, low rotational resistance and low noise, especially for drainage systems, which are not easy to pass laterally slip. The reason why it is called the normal mode is related to the off-road mode and the mud and snow mode. In fact, there are many types of common patterns in general, because each of our large tire manufacturers has its own laboratory and testing ground, where countless engineering information technology managers can study patterns. Anyone but in the process of research, think, pay 2. Horizontal groove pattern: The driving force, braking force and traction force of the horizontal groove pattern are particularly good, and its wear-resistant material performance is excellent. Therefore, it is very suitable for engineering management vehicles such as bulldozers and excavators. The performance of the drainage system is relatively poor. 3. Mud and snow pattern: The Mud and Snow pattern, as the name suggests, is designed for Mud and Snow patterns. When using this type of tire, be sure to remove the cleats on the tread, otherwise, it will damage the road surface, because we need many drivers to buy this type of tire, which does not exist for use in snow.

What are the instructions for the use of polyurethane solid tires?

Polyurethane is widely used in tire manufacturing in various industries. It has strong impact resistance, abrasion resistance, hydrolysis resistance, tensile strength, tear strength, oil resistance, etc., but it should also be used safely. , the following Zhejiang Kunrong Rubber Technology Co., Ltd will share with you the instructions for the use of polyurethane solid tires. Instructions for use are as follows: 1. When the wind pressure of the polyurethane solid tire is too low, the rolling resistance of the tire will become larger, which will cause abnormal heat and stress, and cause the tire to be partially peeled off and damaged; 2. When the wind pressure of the polyurethane solid tire is too high, not only will the ground contact area be small and the braking performance of the tire will be reduced, which will affect the driving safety, but also the driving comfort will be deteriorated due to the ability of the tire to absorb vibration frequency; 3. Different types of tires with different patterns or old and new tires should not be installed on the same axle; 4. The abnormal load will cause the tire to be overloaded and fail. Please ride in accordance with the load limit of the depot, and do not overload; 5. Overspeeding will cause the internal temperature of the tire to rise excessively, and the reduction of the rubber adhesion will eventually lead to failure; 6. Before combining the rim and tire of the polyurethane solid tire, please clean the rim and tire first, and no debris should be left inside.

How do polyurethane tires solve the slipping state?

When using polyurethane tires, it is inevitable to encounter wheel slippage. How to solve this problem, let Zhejiang Kunrong Rubber Technology Co., Ltd. introduce it to you. How to get out of a skid: Slips can happen to even the more cautious driver. If the vehicle is slipping, remember not to press the brake pedal hard. If your vehicle is equipped with an anti-lock braking system (ABS), do not apply the brakes. Instead, you should press the brake pedal firmly and steadily and turn the steering wheel in the direction of the slip. Get ready for the road: Driving with polyurethane solid tires on slippery surfaces requires gentle handling of all major controls (steering, clutching, braking, and accelerator) and constant alertness for accidents and emergencies ahead. When you're on the road in the rain, your shoes can get wet and easily slip off the pedals when you pedal. Before starting the engine, the soles of your shoes should be wiped dry on the car's carpet or rubber feet. All car drivers should regularly check that their car's headlights, taillights, brake lights, and turn signals are working properly. Slippery polyurethane solid tires to avoid braking: Avoid braking. Slow down as much as possible by releasing the gas pedal. Headlights should be turned on even in light rain. Not only does this help you see what's going on on the road, it also helps other drivers see your vehicle. If your vehicle is equipped with daytime running lights, they should be turned on so that vehicles behind can better keep their distance from you.

What are the structural characteristics of polyurethane solid tires?

Polyurethane solid tires and rubber solid tires are widely used in reach forklifts, narrow aisle forklifts, side/multi-directional forklifts, electric stackers, pallet trucks, pallet stackers used in various warehouses, supermarkets, and distribution centers. It is also used for the transmission, guidance and support of industrial and mining metallurgy and equipment assembly lines. The high strength, high load-bearing, high resilience, high wear resistance, high tear resistance and other properties of polyurethane solid tires are unmatched by ordinary natural rubber tires. Polyurethane solid tires have the following characteristics: Polyurethane solid tires are manufactured by casting process, and their structure is very different from the tires currently produced. A full polyurethane pneumatic tire is composed of three parts: the carcass, the belt layer and the tread. Among them, the carcass is made of polyurethane elastomer with higher modulus, which is relatively hard, so it has better fatigue resistance, dimensional stability and cutting resistance; the belt layer on the upper part of the carcass is made of aramid fiber wound in the circumferential direction Or steel cords, and the tread is cast from a low-modulus polyurethane elastomer to ensure the tire's wear resistance and ride performance.

What is the difference between polyurethane tires and rubber tires?

Rubber tires have shortcomings such as short service life, poor wear resistance and tear resistance during use, especially truck tires, which often lead to punctures due to their limited load-bearing capacity. The investment cost of rubber tire production equipment is very high, and some processes need to be manually operated. Even with very advanced molding equipment, the manufacturing quality and the quality of each batch of products cannot be completely uniform. In addition, rubber tires will generate a lot of waste during the use process, and it is very difficult to recycle and reuse them after they are scrapped, which is likely to cause environmental pollution. Polyurethane elastomer is the most wear-resistant elastomer at present, with the advantages of high wear resistance, colorability, high cutting resistance, excellent oil resistance and chemical resistance. Polyurethane tires are more uniform than rubber tires and do not suffer from tread peeling. Cut high temperature.

What is the replacement standard for forklift tires?

Depending on the rubber compound of forklift tires, the vehicle environment and driving habits, the service life of forklift tires will also vary. Generally, forklift tires with a groove depth of less than 1.6 mm can no longer be used, because the drainage performance and puncture resistance of forklift tires will be greatly reduced at this time. In addition, if a forklift tire has been repaired three or four times, the forklift tire can be swapped to a non-drive or rear wheel to reduce the risk of a puncture. The service life of forklift tires is different from the environment and usage methods of different use sites. The details are as follows: 1. Under certain load and driving environment conditions, the forklift tires have a suitable tire pressure. When the forklift tire pressure is higher than the standard value, the tire crown is grounded in the middle, and the contact area between the tire and the road surface is reduced. The load increases, and the wear of the middle of the crown increases. The cord of the tire is overstretched, causing the cord to break, resulting in an early tire blowout. 2. Under normal load and tire pressure, the increase in vehicle speed will cause the deformation frequency of the forklift tire, the vibration of the carcass, and the circumferential and lateral twisting deformation of the tire (forming static waves) to increase. Heat increases. The working performance of forklift tires decreases, and even ply rupture and tread peeling occur, which accelerates tire wear and damage. 3. Road conditions also have a great influence on the service life of the tire, which affects the friction between the tire and the ground and the dynamic load on the tire. 4. High temperature will reduce the breaking strength, elongation and hardness of the rubber, reduce the adhesion strength between the rubber and the cord, and also accelerate the aging of the rubber. Due to the aging of the sidewall rubber and the cracks and the severe deformation of the sidewall, the carcass layer cords are separated from the rubber. Once the tire encounters a sudden load locally, it is likely to have a puncture.

What are the maintenance guidelines for industrial forklift rubber solid tires?

When it comes to forklifts, most people will think of the operation of forklifts. Forklifts are very large and heavy transport vehicles, and forklifts have very high requirements on tires. There is a saying in the tire industry: "Three points of use, seven points of nourishment", so how to maintain the rubber solid tires of industrial forklifts to prolong their life? Zhejiang Kunrong Rubber Technology Co., Ltd. Let me tell you how to maintain the rubber solid tires of industrial forklift trucks.1. Rubber tire selectionIt is very important to choose a suitable and correct forklift solid tire. Different types and patterns of tires must not be mixed arbitrarily due to the actual size and load capacity of each tire.Rubber solid tiresIn addition to the need for air pressure maintenance of pneumatic tires, there is no safety/safety hazard caused by tire blowouts. High-quality/high-quality solid tires are much better than pneumatic tires in many aspects, such as cost performance, maintenance-free and longer replacement cycle. Tires: Under the working conditions of moderate working strength, distance and load, solid tires with side holes with higher shock absorption effect are a good choice for better consideration of safety/safety and comfort/comfort.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 when the forklift is transporting loads, especially when turning, stopping and braking.2. Pay attention to the load indexForklift solid tires should be within the specified load indexUse within the corresponding load capacity. It goes without saying that the heavier the load on the vehicle, the shorter the life of the tires. Especially in the case of overload, it is more prominent.3. Pay attention to speed levelsForklift solid tires should be used within the travel speed corresponding to the specified speed class index. The tires produced by regular solid tire manufacturers are marked with a speed level index.4. Avoid high temperature road conditionsExcessive temperature can easily aggravate forklift solid tire wear and even puncture. When the vehicle is running, the tire temperature will rise due to the expansion, compression and friction of the tire.5. Timely replacementTimely transposition of forklift rubber solid tires, selection of appropriate tread patterns, daily maintenance, regular inspections, timely repairs, and frequent digging of stones and foreign objects in the tread patterns are all important factors to prolong the life of the tire.6. Regular inspectionWatching for early signs of tire damage can prevent unnecessary tire changes. Check your tires at least once a week. Check items are:1) Whether the tire surface has metal chips, broken glass or other impurities that can cause early damage to the tire;2) Check whether there are slight cracks in the tire rubber, early delamination and block loss, to avoid accidents and unnecessary maintenance costs. If found, please remove them in time before use In many cases, don't wait until there is a fault before driving to the repair station for maintenance. Regular maintenance of the vehicle is also closely related to the extension of the life of the rubber solid tires.

How can forklift tires reduce wear?

Frequent replacement of forklift tires is not a good thing. It is not only time-consuming but also causes a lot of waste. So Zhejiang Kunrong Rubber Technology Co., Ltd. hereby reminds you to use forklifts reasonably, which not only saves time and effort, but also ensures long-term safety/safety work. A guarantee, let's take a look: How to reduce the wear of forklift tires? 1. Strengthen the maintenance of tires.Do a good job of land survey and pressure cleaning, check the temperature of the tires, and the grounding holes are blocked.Usually when inflating tires, if it is cold and under a certain load, regularly check and adjust the tire pressure at least once a month; in summer, due to the high ambient temperature, if the tire temperature is too high, reduce the frequency of increase to avoid strong sunlight to the tires , it is recommended to stop in the shade of a tree, instead of directly pouring cold water for cooling or directly venting to reduce pressure. If you are going to leave it in the open parking lot for a long time in winter, you should base it on the tires and don't start accelerating immediately until the tires get hot, and then it becomes normal driving. 2. Improve driving skills.Lift the clutch pedal slowly and steadily when starting off. The maximum speed of driving must not exceed the speed limit of the tire; it should be avoided as much as possible during the process of rapid acceleration, emergency braking and sharp turning. In the case of obstacles such as rocks and potholes, it is recommended that you slow down as much as possible or avoid it directly.3. Improve the maintenance of the chassis.Lubricate and adjust the design value of wheel hub bearing, tie rod ball end, king pin bushing in time according to regulations; keep the balance of the tire, if it is unbalanced, the wheel dynamic balance test should be used to exhaust the one-way valve frequently, and the tire has been oiled. Once the forklift is found Tire into oil, you should immediately remove the tire to clean, and check the air seal at the same time, replace the tire winter tire in the greenhouse to restore / restore elasticity / elasticity, load the rim forklift tire product Apply soap in the fetal port to prevent damage to the port; pivot oil Sealing and brake hydraulic cylinders should be leak-free, and oil- and wet-resistant rubber tires should meet the requirements for lateral and radial swinging wheel assemblies.
