Polyvinyl chloride (PVC) is a white amorphous powder or granule which has thermoplasticity, starts to soften at 80 ° C to 85 ° C, and has a plastic leather shape at 130 ° C. It starts to flow at 180 ° C. Polyvinyl chloride burns on the flame and extinguishes when it leaves the flame. Commonly used in the production of films, hard tubes, electrical appliances, cables, food packaging, and so on.
The use of waste polyvinyl chloride is more complicated, especially in some composite packaging, such as paper-plastic or aluminum-plastic composite film packaging, which cannot be handled in a simple way. Here is a simple method for packaging composite membrane packaging: firstly, the recycled waste polyvinyl chloride composite membrane is sorted, cleaned and degreased, then placed on a tray and baked in a temperature controlled oven. The temperature should be based on the specific temperature. The situation was adjusted. When heated above 80 °C, the polyvinyl chloride began to produce thermal creep. The paper and aluminum had different hot creep temperatures. By adjusting the temperature and baking time, the polyvinyl chloride quickly peeled off. It should be noted that there should be no open flame in the heating equipment, because the PVC will burn when exposed to an open flame; the heating temperature should not be too high, and the temperature will be too high, which will carbonize the PVC; when the PVC is heated, it will cleave a small amount of toxic substances such as hydrogen chloride. The operator should pay attention to protection.
The plastic sole is produced by using waste polyvinyl chloride, and the recovered waste polyvinyl chloride is first cleaned, degreased, and then put into a pulverizer to form a pellet. According to the specific conditions, according to 100 parts by weight of polyvinyl chloride, adding appropriate amount of dibutyl phthalate (DBP), dioctyl phthalate (DOP), di-octyl phthalate (DCP) , alkyl sulfonate cresyl ester (M50), chlorinated paraffin, tribasic lead sulfate, dibasic lead sulphate, barium stearate, stearic acid, pigment, may also be added to the powder Rubber acts as a modifier. After the above components are kneaded, the hot agent can be used to produce the unit, and the hot shoe cold pressing process directly produces the plastic sole. Production costs can be calculated based on actual consumption. The use of waste polyethylene can also produce bicycle pedals, shoe mains, agricultural water pipes, plastic sandals, plastic slippers, beach shoes, micro-porous foam sandals, etc., to be further developed.
