The scraper product is made of ultra-high molecular weight polyethylene (UHMWPE) because of its extremely high melt viscosity, even if it is heated to its crystalline melting point, it is not liquid, and this immobility is due to its ultra-long single molecule The chain is highly tangled. In layman's terms, it is like a pile of hemp rope. Low molecular weight polyethylene such as polyethylene wax is like ten thousand one-meter-long hemp ropes piled together and easily separated; ordinary polyethylene products are like the same one thousand ten meters. Long hemp ropes are entangled together and are not easy to separate, but they can still be separated with a little effort; while ultra-high molecular weight polyethylene (UHMWPE) is like a hundred 100-meter-long hemp ropes. Together, it is difficult to separate them even with a lot of effort.
Scraper blade feature:
1. Non-stick materials:
The surface absorption is very weak, and its anti-adhesion ability is second only to PTEE, and its water absorption rate is almost zero, only 1% of PA6. Coal chips, wet soil, red soil, and other materials with strong viscous viscosity even if the humidity is high. It will not stick to it, and the material's sliding speed has nothing to do with humidity.2. Wear resistance:
The wear resistance of polyethylene liner ranks first among engineering plastics. The higher the molecular weight, the higher the wear resistance, even more than many metal materials (such as carbon steel, stainless steel, bronze, etc.). The mortar abrasion index is only 1/5 of PA66, and 1/10 of HDPE and PVC; compared with metal, it is 1/7 of carbon steel and 1/27 of brass. To
3. Self-lubricating
The coefficient of static friction is 0.07, and it has good self-lubricating properties. It is second only to polytetrachloroethylene (PTFE) without lubricant; it has better lubricity than steel and brass with lubricating oil. It is an ideal lining, the friction part of the equipment, in addition to improving the wear-resistant life, it can also receive energy-saving effects.
4. Anti-corrosion:
The polyethylene liner is not corroded in lye, and has stable performance in 75% concentrated sulfuric acid and 20% nitric acid. It is also stable to sea water and liquid detergents.
5. Impact resistance:
The polyethylene liner has a large molecular weight and a close chemical bond. Therefore, the impact resistance is strong and will not break. The impact strength is 10 times that of nylon 66, 20 times that of polyvinyl chloride, and 8 times that of polytetrafluoroethylene; the impact strength is about twice that of impact-resistant PC, 5 times that of ABS, and more than 10 times that of POM and PBTP. Especially in a low temperature environment, its impact strength reaches a high value, and its flexibility can provide an extremely safe and reliable guarantee for the conveying system.
6. Low temperature resistance:
Polyethylene car plate is a material with excellent toughness, and its low temperature resistance is also very good. It still has a certain degree of ductility at a low temperature of -269°C without signs of embrittlement. Especially suitable for the Northeast and Inner Mongolia area. To
7. Hygiene and non-toxic:
It is tasteless, non-toxic, odorless, non-corrosive, and has physiological inertia and physiological adaptability. beautiful
8. Light weight:
UHMWPE has a density of 0.93-.97, which is the lowest density among many materials and the lightest texture ranks first among engineering plastics. It is easy to install and unload, convenient to use, and provides work efficiency.
