Problems solved by technology

The disposal method of waste plastics produced in my country every year is landfill accounting for 93%, incineration accounting for 2%, and recycling accounting for 5%. Compared with developed countries, the utilization rate of plastic waste materials is extremely low.
On the other hand, the building formwork used in domestic construction projects usually uses steel formwork and wood formwork. Among them, about 10% to 15% of steel formwork is lost during use every year, while the loss rate of wood formwork is 30%. % above, thus causing a waste of resources to a certain extent

Abstract

The invention provides a hot-pressing manufacturing process of plastic building formwork, comprising the following steps: (1) pulverizing raw materials; (2) drying raw materials; (3) stirring raw materials; (4) stirring The raw materials are transported to the twin-screw machine for granulation; (5) After granulation, they are sent to the large material tank with wind for cooling; (6) The cooled granules are transported to the hot press molding machine; (7) Extruded, and then The molded formwork is cooled by a cooling machine; (8) the formwork is cut to achieve the effects of environmental protection and energy saving.

Description

technical field [0001] The invention belongs to the field of plastic building templates, more specifically, it relates to a hot-pressing manufacturing process of plastic building templates. Background technique [0002] With the development of society and the process of industrialization, tens of millions of tons of waste plastics are produced every year in our country. my country's annual disposal of waste plastics is 93% landfill, 2% incineration, and 5% recycling. Compared with developed countries, the utilization rate of plastic waste is extremely low. On the other hand, at present, the building formwork used in domestic construction projects usually uses steel formwork and wood formwork. Among them, about 10% to 15% of steel formwork is lost during use every year, while the loss rate of wood formwork is 30%. % above, thus causing a waste of resources to a certain extent. According to statistics, there are about 500,000 tons of PC (polycarbonate) waste plastics per yea...
