The plastic industry is a young industry that is based on synthetic or natural polymer compounds, which are plasticized under certain conditions.
Fire hazard:
The main raw material for plastic is synthetic resin. The monomers of synthetic resins, such as acetylene, ethylene, propylene, formaldehyde, benzene, etc., are flammable and explosive substances, and the production process is often carried out under high temperature and pressure, which poses a certain fire risk. During the production process, static sparks, equipment friction and ignition can also occur, and even a slight mistake can lead to a huge fire.

Fire prevention measures:
1. Preparation stage for processing:
When batching and mixing, the pump for transporting flammable solvents should be placed below the liquid level of the container, and the pump chamber should always be filled with liquid. The impeller is made of non-ferrous metal to prevent sparks from friction. When mixing powder, magnets should be installed at the feeding port of the machine to prevent iron components from mixing into the material. Ventilation and dust removal, suction and other methods should be used in factories, equipment, and other places to remove dust.
During pre impregnation, as solvents and resins are often flammable, the pre impregnation tank should be sealed to prevent the volatilization of low molecular weight combustibles. The exhaust pipe of the pre immersion tank should lead to a high altitude or safety zone. The pre impregnation process and the semi-finished products after pre impregnation should be heated with hot air, hot water, or steam during drying.
The electric heating wire used for heating during granulation and extrusion should be covered with a protective cover. The body and head of the extruder should be tightly connected. Before driving, the temperature should be raised before adding materials to prevent combustible materials from rushing out and burning in case of fire.
