uhmwpe dewatering element suction box cover :

Dewatering elements from Xinxing Industrial in ultra high molecular weight polyethylene set themselves apart by the special sinter press procedure over a long period used to produce them, as well as an extremely high molecular weight plus their extra additive that is specifically tailored to paper machines. All these benefits ensure what is an outstanding service life for plastic coupled with a low coefficient of friction. Dewatering elements can be used for machines with speeds up to 800 mpm.

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.

White UHMW-PE dewatering element sintered over a long period with the benefit of a high degree of cross-linking. The result: improved endurance.

Pure PE-1000

No additives 

Applicable at machine speeds of up to approx. 600 mpm

The world's first UHMW-PE dewatering element is known for its high dry-film lubricant content. This produces an extremely smooth surface, most importantly resulting in a low friction coefficient a low level of adhesion.

No adhesion

Excellent chemical resistance

Low coefficient of friction

Applicable at machine speeds of up to approx. 600 mpm

UHMW-PE dewatering elements reinforced with cross-linkers & UV stabilizers. UHMWPE is the classic product in this range and offers the best price-performance ratio.

Low adhesion

Excellent chemical resistance

Extremely long service life

Applicable at machine speeds up to approx. 600 mpm

UHMW-PE dewatering element – based on reinforced with glass microbeads. This increases the service life by up to 20%. Unlike ceramic powder, the glass microbeads have no negative impact on the fabric lifetime or the felt lifetime.

Increased wear resistance

Applicable at machine speeds upt to apporx. 800 mpm

Application of ultra high molecular weight polyethylene UPE products
 

Ultra-high molecular weight polyethylene refers to linear structural polyethylene with a molecular weight of more than 7 million. It is the best comprehensive engineering plastic. Its wear resistance, impact resistance, corrosion resistance, self-lubrication and absorption of impact energy are five properties. The best of the plastics, known internationally as "amazing material."

Due to its superior performance, it has been widely used in various sectors of the national industry. UPE has been widely used in textile, paper, packaging, transportation, machinery, chemical, mining, petroleum, agriculture, construction, electrical, food, medical, sports and other fields, and has begun to enter the field of conventional weapons, ships, automobiles and so on.

1. Applications based on wear resistance and impact resistance
1), textile machinery
Textile machinery is the first application area of UHMWPE. At present, there are an average of 30 UPE parts used in each textile machinery in foreign countries, such as shuttles, shuttle rods, gears, couplings, sweeping rods, buffer blocks, eccentric wheels, rod bushings, swinging back beams, etc. Wear parts.
2), paper machine
Paper machinery is the second area of UHMWPE applications. At present, the use of UPE in papermaking machinery accounts for 10% of the total amount, such as the wiper board of the paper machine made by UPE, the suction box cover, the deflector, the hydrofoil, the compacted part, the joint, the sealing shaft, and the partial Guide wheels, scrapers, filters, etc.
3), packaging machinery
Replace the modified fluoroplastic with UHMWPE to make the guide rail, the slider seat of the conveyor, the fixing plate, etc., UPE rail, pad, and barrier (plastic steel).
4) General machinery
UHMWPE can be used to make gears, cams, impellers, rollers, pulleys, bearings, bushings, bushings, pins, washers, gaskets, flexible couplings, screws, pipe clamps, etc. Such as the protective plates of piers and bridge piers.
2, The application of self-lubricating and non-sticky
1), material storage and transportation
UHMWPE can be used to make powder-like linings such as silos, hoppers, chutes, etc., sliding surfaces, rollers, etc. Storage bin lining lining of coal hopper, powdery product bucket, etc.
2), agriculture, construction machinery
UHMWPE can be used to make anti-wear plates, brackets, etc. for agricultural implements.
3), sports supplies
UHMWPE can be used to make skating sleds, sleds and so on.
3. Applications based on corrosion resistance and non-absorbency
1), container packaging
The use of UHMWPE to make warm water containers for solar installations is one of the most widely used areas of UHMWPE.
2), chemical equipment
Use UHMWPE to make chemical industrial parts such as seal fillers, packing materials, vacuum mold boxes, pump parts, bearing bushings, gears, seals and so on.
3), conveying pipeline
4, The application of health and non-toxicity
