Look at the pot noodles: the surface of the pot is smooth, but it is not required to be smooth as a mirror. The irregular light lines on the surface are normal, but if the lines are too dense, it is a
In the selection of plastic packaging containers, it is appropriate to have a general understanding of the various molding methods. The characteristics of various plastics commonly used in plastic pac
The raw material plastics for food plastic barrels are lighter materials, and the relative density is between 0.90 and 2.2. Most plastics have good corrosion resistance to acids, alkalis and other che
Plastic barrels can store liquids, solid chemical products, foods, medicines and dangerous goods; plastic barrels are about the same weight as fiber barrels, but half lighter than steel barrels; plast
1. First of all, consumers need to guide transparent plastic products including polystyrene and plexiglass. Raw materials for translucent plastic products include cellulosic plastics, low density poly
(1) The production process of the iron barrel: Steel plate shearing--rolling (cylinder type)--tubing body welding--welding overlap burr shearing process--weld section differential rolling--trimming
Advantages of steel-plastic composite barrel: Steel-plastic composite barrel production investment is smaller than other products, and the manufacturing process is simple and the market prospect is
Performance characteristics of galvanized iron drum: 1. The galvanized iron drum has special metal luster and is easy to print and decorate, so that the appearance of the product is luxurious and beau
The temperature acceptance scheme of the plastic barrel is usually within the range of minus 40 degrees to 60 degrees. It is assumed that the plastic barrel will be deformed or even split according to
Strong acid and alkali will corrode the plastic barrel of plastic products, so that the plastic barrel will be scrapped early. The plastic barrel should avoid touching strong acid and alkali. The shar
To prevent the plastic barrel from becoming brittle, the temperature of the barrel and nozzle is too low and needs to be adjusted. If the material is easily degraded, the temperature of the barrel and
Plastic chemical barrels are used in chemical and pharmaceutical applications. Because of the special raw materials used in chemical barrels, they have high-strength corrosion resistance and acid and
