Nylon tires are once the main product of China's tire manufacturing enterprises. However, with the rapid development of long-distance transportation industry, the use of tires has developed towards longer life, heat dissipation, and high bearing capacity. New radial steel wire tires are gradually starting to develop. Into the people's attention, get the driver's praise. What is the difference between the two? The following is written by Cheng Li Special Automobile Xiaobian! Â Â

The sidewalls of biased tires consist of layers of overlapping plies, and the crown and sidewalls consist of the same ply structure. The entire carcass is composed of multiple layers of diagonal nylon cords. This structure makes the tire stress concentration, tire tread uneven force, the middle of the serious wear, short tire life. The tire is composed of nylon cords. The heat resistance of the nylon material is poor. After repeated cold and hot alternate driving, the nylon cord fatigues and the tensile force decreases. The deformation of the nylon tire side of the skew line is directly conducted to the tread, the ground contact area of ​​the tire is unstable, and the carcass ply is hinged and worn to cause internal overheating. Many wreckers in use, the sudden explosion of intact tires, economic losses do not say, still a big security risk.
The radial side of the radial cord is relatively independent of the tread cord function, so the ground contact area is large. The carcass consists of a single-layer steel cord ply and has a low running temperature. The crown is fixed by a steel wire belt and can effectively resist punctures and tears. The wear of the tread pattern is average and the tire has a long life. Steel cord material composition, fatigue strength, tensile properties are qualitatively different. Radial wire tires, the sidewall deformation will not be transmitted to the tread, the deformation of the ground contact area is minimized, the tire temperature is low, and it is more fuel efficient. In contrast, radial steel tires have better performance.
The cutting machine is suitable for the cutting of Chinese medicinal herbs including rhizomes,fruitages,leaves,and grasses etc before it being fine processed,grinded or extracted,as well as for the cutting process of foodstuff(sliced fruit,preserved fruit),aquatic products(sliced kelp),tobacco leaves,and tea leave etc.This slicing machine is composed of motor, variable speed mechanism, tool rest, step and retreat material, adjustable tool rest machinery and so on. Due to the use of advanced step feeding, so that the cut of the sheet shape uniform, can freely control the feeding distance, will not cause the material extrusion knife bad situation. Due to the reasonable layout, the machine is easy to operate, light appearance, light weight. This machine is mainly composed of two parts, such as conveying and cutting medicine, machinery and so on.
