Analysis of poor reaction effect of Ultra high molecular weight polyethylene liner used by some User
One, foreword
Ultrahigh molecular weight polyethylene (UHMWPE) has almost concentrated the advantages of all kinds of plastics and has unmatched comprehensive properties of ordinary polyethylene and other plastics. Uhmwpe has the advantages of non-water absorption, self-lubrication, impact resistance, friction resistance, corrosion resistance and non-adsorption. It has been widely used in a variety of silos, to replace the original cast stone, stainless steel and other materials, most enterprises in the use of the process of the effect is very good, but also some enterprises reflect the effect is not good. By our factory business personnel in the relevant enterprises around the market survey, visit, found several several situations :(1) the material is not smooth; (2) The lining board is broken; (3) The lining plate is broken; (4) The lining board falls off.
Second, situation analysis
In view of the above situation, we analyze it as follows:
1, the material is not smooth
An enterprise found that the silo was not smooth in the production process, and the problem still existed in the operation process when the polymer polyethylene liner was installed. According to the site investigation and analysis of technicians, there are four reasons for this phenomenon:
(1) The design of the silo body is unreasonable
(2) Material arch bridge
(3) The material is in the shape of a well barrel
(4) Material accumulation.
