Construction Method Of UPE Sheet
In the technical and technical articles, it can be understood that the ultrahigh molecular weight polyethylene sheet has a very high molecular weight because the molecular chain of the ultrahigh molecular polyethylene is entangled, the viscosity is extremely high, and there is almost no fluidity. It is difficult to form a product by processing it with general processing equipment. At present, the processing of ultra-high molecular weight polyethylene sheets is mostly performed by sintering molding.
Plunger extrusion is also used but the yield is very low. When the ultra-high molecular weight polyethylene sheet is produced by the molding method, the following production process is generally adopted: the quality of the raw materials used determines the quality of the sheet product. The use of high-quality raw materials with a molecular weight of more than 3 million is scientifically formulated, and a reasonable process can obtain high-quality products.
The processing technology of the batched ultra-high molecular weight polyethylene sheet is constantly evolving. Through the transformation of ordinary processing equipment, the ultra-high molecular weight polyethylene (UHMW-PE) has been developed from the initial press-sintering to extrusion, blow molding and injection. Molding and other special methods of forming. Then the main construction method for ultra high molecular weight polyethylene sheet.
How much do you know about it? Let's take a closer look: When the base concrete is relatively flat, it is not advisable to make a bottom ash leveling layer to avoid the formation of a bad insulation layer and cause the whole piece of the material to peel off. Before lining, the oil, dust and other attachments on the base layer must be carefully cleaned. For the upper surface of the concrete base layer, it should be pre-leveled and removed.
