In the process of using the ultra-high molecular weight polyethylene board, the first installation of the ultra-high molecular weight polyethylene board is the first step that everyone needs to operate correctly, so how to make it install reliably?

First of all, let's master the high-quality characteristics of UHMWPE sheet. UHMWPE sheet is a special plastic with excellent characteristics, such as high wear resistance, impact resistance, and low friction. coefficient, good self-lubricating properties, high-quality low temperature resistance, chemical corrosion resistance, etc., such high-quality plates must have a wide range of applications. To ensure the reliable installation of ultra-high molecular polyethylene plates as much as possible, we What factors can you start with?

UHMWPE is a very high viscosity polymer in powder form with a typical particle size range of 100-200 microns. Due to its high viscosity, it can not usually be produced and processed by ordinary thermoplastic molding methods, but only by molding or plunger extrusion processing technology, the ultra-high molecular weight polyethylene particles are melted and sintered into billets or profiles under high pressure. If so, perform subsequent machining. Because UHMWPE sheets combine the following excellent properties: high abrasion resistance, high impact resistance, non-stick surface and self-lubricating properties.

Why are the materials such as ultra-high molecular weight polyethylene board, coal bunker lining board, coal bunker sliding plate, silo lining board, UPE wear-resistant lining board not sticky? Because this material has a very low water absorption rate, that is, it will not seep water. In layman's terms, a glass of water is poured on the board. Except for natural air-drying, the board will not absorb a little water. In addition, polyethylene itself is extracted from petroleum, and it has a certain self-lubricating property, so it does not stick to materials and does not stick to coal.

During the installation process, the flat surface of the bolt countersunk head of the polyethylene sheet must be lower than the board surface; the use of bolts per square meter should not be less than 10 during the installation of the sheet product; the gap between each sheet should not be greater than 0.5cm. It is also important to note that in the event of large changes in operating or ambient temperature when installing the UHMWPE liner, the form of attachment of the liner must account for its expansion or contraction. Any fixing method should be designed to facilitate the flow of bulk materials, and the screw head is always embedded in the liner. For thicker liners, the seam should be cut at 45 degrees.
