Analysis Of Polyethylene Liner In The Chemical Industry With Unique Advantages
Customers know that you used, the wear of uhmwpe liner and drug resistance in chemical machinery with unique advantages. Replace the metal with ultra high molecular weight polyethylene made of acid-resistant pump, transmission machinery, pumps, bushings, gasket, and other gear, not only greatly extend the service life and cut costs considerably. Ultra high molecular weight polyethylene Board also can be used as performance additives, added to achieve the objective of improving its chemical properties in other compounds. Such as the use of vibration-rotation mixer allows permeable polypropylene melt ultra high molecular weight polyethylene, made amorphous ultra high molecular weight polyethylene and polypropylene into complex network structure, thereby improving elongation and yield strength of polypropylene. Can also be used as ultra high molecular weight polyethylene polypropylene impact strength modifier, tensile strength modifier and toughening and reinforcing agents.
Ultra high molecular weight polyethylene Board as the material of the liner in the coal bunker of coal bunker funnel has been widely, it attracted the attention and concern of the industry for a long time, because of its special abrasion resistance, low coefficient of friction and impact resistance with excellent anti-corrosion performance is so far than many materials. As material warehouse, and real hopper and coal warehouse lining Board using initially is see end and abroad reported, in recent years some introduced project in the also used has this super polymer volume polyethylene Board, and gradually in power plant, and steel enterprise, and mine and Terminal, industry in the widely using, its environmental of characteristics and unique of material nature makes it by welcomes degree very high, also adapted has social development on environmental of requirements. Ultra high molecular weight polyethylene plate in the coal bin liner in actual use is more or less has a problem with, is part of the coal bunker lining irregular shedding can occur.
Exceeding polyethylene sheet used as liners, is using its mechanical properties are not high, often used as a lining material of metal, sheet metal strength and ultra high molecular polyethylene wear and performance necessary for clients together. Flame retardant polyethylene panels, widely used in electric power, coal, steel, cement, coke industry, effectively prevent fire caused by spontaneous combustion of coal and other factors. Through analysis, the occurrence of this problem is not the quality of the product itself, but has a great relationship with all aspects of the process. Bunker liners installation quality, choice of sizes, cutting forms and so on.
In many cases, is seen by everyone, ultra high molecular weight polyethylene plate thickness 3~120mm, color translucent and white, colors can also be specified by the user. Ultra high molecular weight polyethylene Board with excellent chemical stability, good acid, alkali, salt corrosion. Ultra high molecular weight polyethylene Board with excellent anti-aging properties, under the natural sunlight conditions, its aging life for 40 years. Ultra high molecular weight polyethylene sheet is based on ultra high molecular weight polyethylene raw material, according to customer requirements to join the modified materials, Hybrid--cooling--pressing – sintering – high pressure setting – release – shape.
General ultra high molecular weight polyethylene Board with higher impact resistance, twice times the impact strength of about PC, POM, PBTP, more than 10 times. Such a high impact resistance, and that selection is usually shock approach to cracking damage. Ultra high molecular weight polyethylene sheets impact strength increase with the progress of the molecular weight and molecular weight is 1.5 million at the maximum, especially in the low temperature impact resistance.
