Manufacture
All materials are produced through lengthy sinter pressing processes with extremely long press cycles.
This enables us to produce covers up to 12 m long with no welding seams and also ensures a tension-free
internal structure compared with the typical standard sinter press process and extrusion.
Assembly
PE dewatering elements for paper machines have a high level of thermal expansion. They must therefore be installed in such a way that enables the strips or covers to expand without restriction (T-bars, corner strips, dovetail guides, screws in elongated holes). The base frame support must have a grid of approx. 250 mm to ensure flawless functionality for our covers. This support must extend to the underside of the cover to ensure it has a flat installation surface. Xinxing plastic parts are made from ultra-high molecular weight (UHMW) polymer having a molecular weight of 5 million and greater. XINXING Manufacturing Company has been processing UHMW resin for over 10 years. This true hdpe polymer is excellent for resisting abrasion and corrosion while contributing a low coefficient of friction.
Fabricated XINXING parts have helped companies improve performance, reduce downtime, eliminate the need for lubrication, replace steel parts and lower their operating costs.
Feature
1. The duration of HDPE is longer than steel, and its abrasion resistance is 3-7 times as long as the carbon steel and stainless steel. It is low coefficient of friction, self-lubricating, non-absorbent, non-adhesive materials and has high impact strength.
2. It has sound mechanical properties, acid, alkali aging resistance, salt corrosion,low temperature, health, non-toxic, light weight, the proportion of steel 1/8. Therefore, it is the best material used as bulk materials storage and transportation equipment lining, such as silos, flow ducts. It is widely used in electric power, steel, coal industries etc.
3. HDPE) sheet with high wear resistance, corrosion resistance, impact resistance, self-lubricating. can be made with coal, cement, lime, slag, salt, cereals, powdered material hoppers, silos, chute lining. Because of its excellent abrasion resistance,self-lubricating and non-sticky, so that the powdery material for storage and transportation equipment, adhesion phenomenon does not occur, to ensure a stable transport.
4. This high wear plate installed applications to adapt to a variety of environmental conditions, can be designed to assemble the connection structure according to user requirements, ease of installation and maintenance. If the operating conditions are very difficult to install underground mine hopper, chute applications, metallurgical industry, feed hopper, etc., can solve the transportation process bonding and sealing material of this long-standing problem, to achieve safe, efficient and normal production.
5. Application field: It can be Ultra-high molecular weight polyethylene HDPE) sheet with high wear resistance, corrosion resistance, impact resistance, self-lubricating. widely used in transportation of liquid, solid, solid-liquid mixture in the funnel, drain tank flap, scraper conveyor chute mining, coal preparation plant, metallurgical industry, power plant, shipbuilding and other sectors, sieve jigger, flotation machine liner, liner board cargo vessels, large slide, tub, dump trucks and other cars lining of wear and corrosion applications, with the unique advantage of value for money.
Advantage
Compared to other polymer material, it has the advantages of low friction coefficient, low wear, and high chemical corruption resistance, high resistance to impact, pressure, freezing, heat insulation, self-lubrication, resistance to dirt generation, resistance to breaking and stress, sanitation, etc. It's used to produce pipe with self-lubrication and high resistance to dirt generation. For instance, min. Friction coefficient is 0.07~0.11, that's equal to the friction between ice and ice
.It's Gives Important Properties.
1.very High Abrasion Resistance
2.very High Impact Strength
3.very Low Coefficient Friction And Good Self-lubricants Properties
4. Chemical Resistance
5 Resistance Under Low Temp.
6.Dielectric Properties
HDPE
) or HPPE (High Performance PolyEthylene), is a polyolefin resin of very high molecular weight (mass) usually between 2 and 6 million g/mol with extremely long chains produced by gel spinning (wet or dry methods). The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made.
HDPE is odorless, tasteless, and nontoxic. It is highly resistant to corrosive chemicals except oxidizing acids, has extremely low moisture absorption (Hydrophobic), very low coefficient of friction, self-lubricating and highly resistant to abrasion, in some forms being 15 times more resistant to abrasion than carbon steel. Its coefficient of friction is significantly lower than that of nylon and acetal, and is comparable to that of polytetrafluoroethylene (PTFE, Teflon), but HDPE has better abrasion resistance than PTFE. HDPE material floats in water thus gaining another advantage over many other materials such as Polyester, Nylon, Aramids, LCP.
HDPEmaterial can be classed as a specialty engineering plastic. It is an indispensable product in world markets having an incomparable combination of abrasion resistance, surface lubricity and impact strength, combined with the excellent chemical properties of HDPE. It competes primarily with Polyacetal, Nylon, PTFE and, in fiber form, with Polyaramid, but it also has many markets that are uniquely its own.
UHMWPE ropes are increasingly replacing steel and conventional fibers in the shipping and offshore businesses of oil & gas, aquaculture, wind mills and cables and lately, experimentally, in ships' cranes. These high performance ropes are stronger than steel and ~1/8 of the weight of comparable steel wires.
