Chemical plastic barrel distortion and the production proces

Chemical plastic barrel distortion and the production processes are closely related

 

If chemical plastic bucket used equipment generates liquid chemical reactions, precautions should be to confirm their reaction and is able to withstand the temperature. Liquid plastic bucket usually means, at room temperature, salt, alkali and other mixtures, are no problem. Plastic bucket can not be used means strong oxidizing liquid, say the temperature is above sixty degrees, concentrations higher than 75% of sulfuric acid, the concentration is higher than thirty percent of concentrated nitric acid and the like.

      Chemical plastic bucket in the actual use of the process, because the entire tank wall thickness difference is too large, causing deformation of chemical plastic barrels, which has caused plastic machinery manufacturing enterprises attach great importance, has started work in this area to improve, Most chemical plastic bucket manufacturers in the mold device also actively made improvements. Blow chemical plastic bucket can fundamentally divided into two categories: extrusion - blow molding and injection - blow molding. The main difference between the two lies in the preparation of the parison and then blow the same fundamental process. Unfolded at the foundation of these two approaches are forming: Extrusion - stretch - blow molding (referred to squeeze - pull - blow), injection - stretch - blow molding (referred NOTE - pulling - blowing) and multi-enantiomer plastic and so on.
