After more than 20 years of development in blow molding, industrial production has become more and more standardized, and the improvement of production efficiency also requires prevention of potential hazards and defensive measures.
Safety factors to be paid attention to in the process of plastic processing as follows:
Electricity and plastic processing equipment are powered by electricity, so you must pay attention to the safety of electricity and prevent potential safety hazards such as electric shock and circuit fire.
Heat, whether it is injection molding, extrusion, blow molding, or curing of thermosetting plastics, a certain temperature is required in the plastic processing process to make the material flow, and the molding operation must be done to avoid scalding.
Machine damage, plastic processing equipment usually consists of motors, transmission boxes, screws, hydraulic components and mechanical parts. If improperly operated, it may cause serious mechanical damage.
Fire, some plastics are easy to decompose to produce flammable gas during thermal processing, or the melt contacts with air at high temperature to produce exothermic oxidation reaction, which eventually leads to spontaneous combustion. During the thermal processing of some red phosphorus flame-retardant plastics, if the heating time is too long, the red phosphorus will undergo a phase transition to form white phosphorus, which may cause a fire.
Dust and toxic gas damage: Toner, filler, glass fiber, etc. must be used in the processing of certain plastic products. These substances may cause human allergies, and inhalation of the respiratory tract may cause severe acute or chronic diseases. In addition, thermal decomposition may occur during the processing of various plastics such as polyoxymethylene, polyvinyl chloride, and polyphenylene ether, and the generated gas may have a certain toxic effect on the human body. Therefore, it is necessary to pay attention to the ventilation of the production environment.
