In the processing of plastic bucket practicality explained

- Mar 19, 2020-

The heat acceptance scale of plastic bucket is generally within - 40 ℃ to 60 ℃. If the temperature is exceeded, the plastic bucket will be deformed or even cracked. So when we use it, we need to ensure that the temperature does not exceed this scale. If we need to exceed this temperature, we need to take some preventive measures, such as putting a plastic bucket around, or other preventive measures.

Therefore, it is necessary to know that plastic buckets can not be used for strong oxidizing liquid devices, such as sulfuric acid with temperature higher than 60 ℃, sulfuric acid with concentration higher than 75%, concentrated nitric acid with concentration higher than 30%, etc.

In the production of plastic buckets, the primary process is through raw material preparation, blow molding, injection molding, mold trimming, scrap crushing, boring, assembly, final inspection and warehousing. It takes ethylene as the primary raw material, and then selects slurry polymerization or gas-phase polymerization process under the effect of catalyst. The obtained polymer is processed by flash evaporation, separation, drying, granulation and other processes to obtain the finished product with uniform particles. Among them, the extrusion includes sheet extrusion, film extrusion, pipe or profile extrusion, blow molding, injection molding and roll molding.
