Product Description

Product Description

The suction box dewatering is based on the suction effect of the vacuum pump, which generates a high pressure difference between the top and bottom of the paper to force the dewatering of the wet paper. It is hoped that the regrind department can transfer the paper to the press department with a higher dryness.
UHMWPE suction box covers and blades are made of UHMW-PE material .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
 Dewatering elements 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.

Advantage

The measured co-efficient of friction for  material is 0.08 which comp- ares very favouralby with other plastics where the friction is between 0.16 and 0.20,or cross grain wood of 0.3.
Faster machine speeds can be achieved through the low coefficient of friction.˙ Less motive power required to drive machines.
The material has a high impact strength and cannot break or splinter . Temperature resistent to 1000C.

Main Feature

1.Excellent self-lubricating performance;

2.Good in resisting impact, flexibility;

3.Being excellent in resisting chemical corrosion(acid, alkali, salt);

4.Being free from toxin, smell or exudates;

5.Good electric resistance;

6.Low in water absorption;

7.Low coefficient of friction;

8.Resisting environment and anti-aging;

9.Resisting high and low temperature;

10.UV resistance

11.Extremely high anti-abrasion.

Assembly

 UHMWPE 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

Application

On paper and pulp industry
At machine speeds of up to approx. 800 m/min 

Packaging & Shipping

The normal package is wooden box(Size: L*W*H). If export to european countries,the wooden box will be fumigated.If container is too tigher,we will use pe film for packing or pack it according to customers special request.
