How to improve the durability of polymer polyethylene sheet

Jun 17, 2019

Polymer polyethylene sheet has now been gradually widely used, the ultra-high performance of the plate, I believe that we should all understand, then about the durability of ultra-high molecular weight polyethylene sheet, we know how much, if we operate properly, can also effectively improve the durability of the plate. Ultra-high molecular weight polyethylene plate was originally used in warehouse liners and required to be stored at two-thirds of the capacity of the entire warehouse before unloading. Typically used in environments that are not larger than 80 degrees C. To prevent the direct impact of materials on the liner, the material and flow of the warehouse shall not be changed at will, otherwise it will affect the application life of the liner, resulting in damage to the quality. Its construction and firmware must not be damaged by external forces. Under the low temperature condition, in order to prevent the presentation of the clump condition, we should shorten the storage time of the materials in the warehouse as much as possible. Sticky materials should not be placed in the warehouse for long periods of time to prevent the presentation of lumps. Other materials should not exceed more than three days in the warehouse storage moment, small water content of the material warehouse stop time can be relatively extended according to the actual situation.


Operating in this way will certainly greatly improve the durability of ultra-high molecules. Ultra-high molecular weight polyethylene plate is a high-quality polymer plate, has been gradually widely used, we produce ultra-high molecular weight polyethylene plate in the material selection and processing process have higher requirements and operating specifications, spare parts on the surface treatment, such as coating treatment can greatly increase the life of spare parts, The difference of spare parts production materials will also have a great impact on the quality and life of spare parts, which also forms the spare parts in the market price due to the material and process of different phenomena.


And the roller supporting the use of the press head, this pressure head action is to first press the lid to the tank, followed by the roller rolling to complete the roll task. For ultra-high molecular weight polyethylene plate, itises because it constitutes the raw material ultra-high molecular polyethylene has excellent high temperature resistance characteristics, and then it can maintain normal operation in a certain high temperature environment. Therefore, ultra-high molecular weight polyethylene plate in the market seems to be a relatively commonly used material, at first ultra-high molecular weight polyethylene plate as a warehouse liner, when the warehouse storage to two-thirds of the time, in order to prevent the impact of materials on the liner, this time can only adjust the warehouse material and flow.


In fact, the temperature is too low will also affect the life of polyethylene sheet, should try to shorten the storage time of the warehouse.


We must follow the instructions for the specification of operation, only in order to effectively extend the life of ultra-high molecular weight polyethylene plate.


Polymer polyethylene sheet Ultra-high molecular weight polyethylene plate has a variety of excellent performance, in a number of industries have been used, such as electricity, docks, coal silos and so on.


Practical analysis has learned that the reason why this ultra-high molecular weight polyethylene plate can be so widely used, the main reason depends on its unique characteristics. At present, the industry standard ultra-high molecular weight polyethylene plate size unique characteristics are the appropriate combination of four basic variables: density, molecular weight, molecular weight distribution and additives. Different catalysts are used to produce custom special-performance polymers. These variables combine to produce HDPE grades for different uses; With good chemical stability, it can resist most acids, alkalis, organic solutions and hot water erosion.
