Each component of a high-quality product should have good quality, so as to ensure the overall good quality of the product. If some of the quality errors occur, the overall quality of the product will decrease, and the buffer strip will be the same. :
Ultra-high molecular polyethylene board features:
1. High wear resistance, its wear resistance is plastic to crown, 4 times higher than nylon, 9 times higher than HDPE and HPVC, 9 times higher than metal compared with metal, wear resistant in erosion environment The damage rate is about 20 times that of A3 steel;
2, high impact resistance, impact strength is 2 times that of PC, 5 times of ABS;
3, high self-lubricating, low friction coefficient, about 0.05-0.11, comparable to PTFE, better lubrication performance than steel and copper plus lubricating oil, under water lubrication conditions, UHMW-PE The dynamic friction coefficient is half lower than PA-66 and POM;
4, excellent non-absorbent, UHMW-PE has low water absorption, 0.01% is only 0.1% of PA-6;
5, excellent non-stickiness, its surface adsorption is very weak, its anti-adhesive ability is second only to the non-sticky PTFE in plastic, so the surface of the product is not easy to bond with other materials;
6, excellent chemical corrosion resistance, can withstand a variety of corrosive media (acid, alkali, salt) and organic media within a certain temperature and concentration range.
Rubber elastomer:
When the shock absorber is subjected to impact, it mainly plays a good buffering role through the physical elasticity of the elastic material. Therefore, the rubber elasticity must meet certain conditions. The rubber used in the international buffer strip has a elasticity of about 55 degrees for the Shore, rubber. Must also have a certain degree of corrosion resistance (if the rubber used in the downhole must be treated flame retardant rubber), and have a certain tear resistance, tensile strength, elongation at break, adhesion strength of rubber and metal profiles Etc. is also the standard of assessment. Therefore, when selecting a manufacturer, it is best to choose a manufacturer with the ability to inspect and test equipment. When comparing experiments with domestic manufacturers, it is found that some companies publicize better performance indicators, but the most basic rubber hardness has not been reached. After testing some manufacturers hardness of about 70 degrees, this hardness does not play a material buffer.
Bonding technology:
How to bond the three different properties of the materials together is one of the difficulties that plague the manufacturers. At present, the two domestic bonding technologies, thermal vulcanization bonding technology and cold bonding are mainly used, but the cold bonding technology cannot Solving the problem fundamentally, the tearing of the bonding layer occurs during long-term use, so the thermal vulcanization technology is the key to solving the problem. Metal skeleton: The method of fixing the buffer strip and the buffer bed frame body in the international or domestic is roughly divided into two types, one is steel structure, the other is aluminum alloy connection structure, the steel structure is durable, not deformed, and is fixed. It will gradually replace the aluminum alloy structure. From the scope of use, both the steel structure and the well can be used. However, the aluminum alloy structure, international and China are prohibited from using this connection structure underground (related coal mine safety regulations), so Any company claiming that the aluminum alloy structure can be used downhole and issuing relevant flame retardant certificates is a deceptive consumer behavior. The domestic market is not the manufacturer's reluctance to adopt this steel structure, but there is no such technology. From the connection structure, the connection method is required for the bonding performance of rubber and steel structure, and special heat vulcanization must be adopted. Connection technology (unlike the general bonding method), but few companies in China have this technology, which makes many companies give up this scientific connection, using aluminum alloy connection, but the direct result of this connection is The fixing is not firm and the buffer strip is prone to sway.
