UHMWPE board UHMWPE board fender veneer antistatic UPE board seabed board

  UHMWPE board UHMWPE board fender veneer antistatic UPE board seabed board & quot; UHMWPE board UHMWPE board fender veneer antistatic UPE board submarine board is made of UHMWPE with molecular weight of more than 1
5 million
UHMWPE board is produced by die pressing technology
Main features: UHMWPE board UHMWPE board fender veneer has excellent performance due to its high molecular weight, and it is of moderate price Thermoplastic engineering plastics with excellent performance almost concentrate the advantages of all kinds of plastics
It has the incomparable comprehensive properties of ordinary polyethylene and other engineering plastics, such as wear resistance, impact resistance, self lubrication, corrosion resistance, impact energy absorption, low temperature resistance, sanitation and non toxicity, not easy to adhere, not easy to absorb water, low density and so on
In fact, there is no pure polymer material with so many excellent properties Wear resistance UHMWPE board UHMWPE board fender veneer antistatic UPE board seabed board has the highest wear resistance among plastics and exceeds some metals
Figure 1 shows the comparison of wear resistance between UHMWPE and other materials
As can be seen from Figure 1, compared with other engineering plastics, the mortar abrasion index of UHMWPE is only 1 / 5 of PA66 and 1 / 10 of hepe and PVC; Compared with metal, it is 1 / 7 of carbon steel and 1 / 27 of brass
This high wear resistance makes it difficult to test its wear resistance by general plastic wear test method
Therefore, a mortar wear test device is specially designed
The wear resistance of UHMWPE is directly proportional to the molecular weight
The higher the molecular weight, the better the wear resistance
Impact resistance the impact strength of UHMWPE ranks first among all engineering plastics
Figure 2 shows the impact strength of UHMWPE compared with other engineering plastics
It can be seen from Figure 2 that the impact strength of UHMWPE is about twice that of impact resistant PC, 5 times that of ABS and more than 10 times that of POM and pbtp
The impact resistance is so high that it is difficult to break it by using the usual impact test method
The impact strength increases with the increase of molecular weight, reaches a greater value when the molecular weight is 1
5 million, and then decreases gradually with the continuous increase of molecular weight
It is worth noting that it can also maintain excellent impact strength in liquid nitrogen (- 195 ℃), which is not available in other plastics
In addition, it has higher surface hardness under repeated impact Self lubricating UHMWPE board UHMWPE board fender veneer has very low friction coefficient (0
05 ~ 0
11), so it has excellent self-lubricating performance
Table 1 shows the comparison of friction coefficient between UHMWPE and other engineering plastics
It can be seen from table 1 that the dynamic friction factor of UHMWPE is 1 / 2 of PA66 and POM under water lubrication, which is second only to polytetrafluoroethylene (PTFE) with better self lubrication in plastics under no lubrication; When it works in sliding or rotating form, it has better lubricity than steel and brass with lubricating oil
Therefore, in the field of tribology, UHMWPE is known as a friction material with very ideal cost / performance
Chemical resistance UHMWPE board UHMWPE board fender veneer antistatic UPE board seabed board has excellent chemical resistance
In addition to strong oxidizing acid, it can resist various corrosive media (acid, alkali, salt) and organic media (except solvent) within a certain temperature and concentration range
It was immersed in 80 kinds of organic solvents at 20 ℃ and 80 ℃ for 30 days, and there was no abnormal phenomenon in its appearance and almost no change in other physical properties Impact energy absorption UHMWPE has excellent impact energy absorption, and the impact energy absorption value is higher in all plastics, so it has good noise damping performance and excellent sound clipping effect
Low temperature resistance UHMWPE board UHMWPE board fender veneer has excellent low temperature resistance and ductility at liquid helium temperature (- 269 ℃), so it can be used as low temperature resistant parts in nuclear industry
Hygienic and non-toxic UHMWPE is hygienic and non-toxic, and can be used in contact with food and drugs
The surface adhesion ability of non stick UHMWPE board, UHMWPE board and fender veneer is very weak, and its anti adhesion ability is second only to PTFE with better non stick in plastic, so the product surface is not easy to stick with other materials
Low water absorption, UHMWPE board, UHMWPE board, fender veneer, low water absorption; Generally less than 0
01%, only 1% of PA66, so it is generally not necessary to dry before forming
The density of UHMWPE board UHMWPE board fender veneer antistatic UPE board seabed board is relatively low compared with other engineering plastics
Tensile strength is due to the ultra high molecular weight polyethylene plate UHMWPE board fender panel anti-static UPE board, the submarine board has the necessary structural characteristics of stretching orientation
Therefore, it has the unmatched super high tensile strength
Therefore, the fiber with super high modulus and strength can be obtained by gel spinning
Its tensile strength is as high as 3 ~ 3
5GPa, and the tensile elastic modulus is as high as 100 to 125GPa
The specific strength of fiber is higher than that of all fibers commercialized so far, 4 times larger than carbon fiber, 10 times larger than steel wire and 50% larger than aramid fiber
Aging resistance UHMWPE board UHMWPE board fender veneer has good aging resistance, longer service time and cost saving
Energy absorption uses the energy absorption characteristics of UHMWPE board, UHMWPE board and fender veneer, which can be widely used in the mechanical equipment industry for steel surface, reduce friction and improve efficiency
Flame retardant ultra high molecular weight polyethylene (UHMW-PE) has flame retardancy by adding flame retardant
Industry application of UHMWPE board UHMWPE board fender veneer products: because UHMWPE board UHMWPE board fender veneer has good wear resistance, environmental protection, anti-static, cushioning, high wear resistance, moisture resistance, corrosion resistance, easy processing, shock absorption, no noise, economy, no deformation, impact resistance and self lubrication, Therefore, it is very suitable for making all kinds of wear-resistant mechanical parts, such as supporting wheel, shaft sleeve, nozzle and mixing blade Application examples of UHMWPE board and UHMWPE board fender veneer: transportation machinery guide rail, conveyor belt, conveyor slider seat, fixed plate, flow production line timing star wheel, food machinery star wheel, bottle feeding counting screw, filling machine bearing, bottle grabbing machine parts, washer guide pin, cylinder, gear, roller, sprocket handle, papermaking machinery suction tank cover plate, deflection guide wheel, scraper Bearing, blade nozzle, filter, oil reservoir, anti-wear strip, felt cleaner, textile machinery opener, shock absorber baffle, connector, crankshaft connecting rod, shuttle rod, flower sweeping needle, deflection rod bearing, swing rear beam construction machinery, agricultural machinery bulldozer pushing into plate material, dump truck compartment material, tractor pear knife lined chemical machinery valve body, pump body, washer, filter, gear Nuts, sealing rings, nozzles, cocks, shaft sleeves, corrugated pipes, port machinery, ship parts, side idlers for bridge cranes, wear-resistant blocks and other spare parts
