Plastic Additives, also known as plastic additives, are compounds that must be added to polymers (synthetic resins) to improve their processing properties or to improve the properties of the resin itself. For example, in order to reduce the molding temperature of PVC resin, to make the product soft and added plasticizer; Another example is to add foaming agent in order to prepare light weight, anti - vibration, heat insulation, sound insulation foam plastics; The thermal decomposition temperature of some plastics is very close to the molding temperature, and the molding cannot be done without adding heat stabilizer. Therefore, the plastic assistant agent occupies a particularly important position in the plastic forming process. A class of auxiliary agents for plastic molding products, including plasticizer, heat stabilizer, antioxidant, light stabilizer, flame retardant, foaming agent, antistatic agent, mildew agent, colorant and whitening agent (see pigment), filler, coupling agent, lubricant, mold release agent and so on. Colorants, brighteners and fillers are not special plastics chemicals, but the general use of materials.

2. The placement of goods exceeds the shelf level of the shelves.
3, improper selection of materials, customers in the purchase of shelves, encountered a number of bad shelves manufacturers, cut corners, fill in the excess, so that the shelves are deformed.
4, improper handling equipment operations.
How to avoid shelf deformation:
1, choose high-quality steel.
2. The goods are evenly distributed on the shelves of the store, avoiding the goods being placed in the same position.
3, pay attention to the operation when handling metal shelves.
1. The uneven weight distribution will cause deformation of supermarket shelves.
