UHMWPE Coal Bunker Liner

1. Non-stick material
The surface adsorption capacity is very weak, and its anti-adhesion
capacity is second only to PTFE. The water absorption rate is almost zero, only 1% of PA6. The coal dust wet soil, red soil, and other sticky cargo materials will not stick to it even if the humidity is high.

2. Wear resistance
The wear-resisting property of polyethylene lining ranks first among engineering plastics, molecular weight is big wear-resisting more number, exceed even a lot of metallic material (if carbon steel, stainless steel, bronze etc.).
The slurry abrasion index is only 1/5 of PA66, and 1/10 of HDPE and PVC. Compared with metal, it is 1/7 of carbon steel and l/27 of brass.

3. Self-lubrication

The static friction coefficient is 0.07, good self-lubrication, second only to poly tetrachloroethylene (PTFE) in the condition without lubricant.
It is more lubricating than steel or brass.
Is an ideal lining, equipment friction parts, in addition to improve wear life, but also received energy efficiency.

4. Corrosion resistance
Polyethylene lining is not corroded in alkali liquor, and is stable in 75% concentrated sulfuric acid and 20% nitric acid.

5. Impact resistance
Polyethylene liner has large molecular weight and tight chemical bond. Therefore, it has strong impact resistance and will not break.
The impact strength is 10 times that of nylon 66, 20 times that of polyvinyl chloride and 8 times that of tetrafluoroethylene.
The impact strength is about 2 times that of the impact resistant PC, 5 times that of ABS, and more than 10 times that of POM and PBTP.
Especially in the low temperature environment, its impact strength reaches the maximum, and its flexibility can provide a very safe and reliable guarantee for the conveying system.

6. Low temperature resistance
Polyethylene lining board is a kind of excellent toughness material, it also is very good, good low temperature resistance performance of in - 269 ℃ low temperature, still have certain ductility, and shows no sign of embrittlement.
Especially suitable for northeast China and Inner Mongolia region.

7. Non-toxic
It is tasteless, non - toxic, odorless and non - corrosive.

8. Light weight
The density of UHMWPE is 0.93-.97g/cm cubed, which is the smallest density among many materials, and the lightest one among engineering plastics.

If the lining board is installed in the cement bin, can use the expansion method, very strong If it's in a steel silo, you need to use penetration or soldering.
The advantage of perforation method is that the installation is relatively close, and the plate and installation plate are close together. If the sheet plate is installed in the steel silo, this method is recommended.
The welding method is considered for the thickness of thick plates above 15mm and the installation in the steel plate cabin The cutting method of the board
Alloy saw blade

The welding has welded joint, so the thick plate can fit well with the steel plate if the hole is made. If the thin plate is drilled, the remaining thickness is less, which can easily cause the whole plate to fall off.

1. Weld the screws on the board.

2. Put the processed boards on the steel plate, and the tools for drilling the sunk holes are as follows：

3. Fix the plate and steel plate with special screws

After the lining board is installed, if the material is often piled up on the edge, the edge protection shall be installed to prevent the board from sliding down.
