The PE blowout machine is pushed by the friction between the plastic and the screw and the plastic and the barrel and the collision between the particles. At the same time, the plastic is melted because of the external heating of the barrel. The molten plastic is filtered out and the impurities are removed from the mold, and the finished film is rolled into the tube by cooling, blowing and so on.
PE film blowing machine degradable PVA plastic can be pure starch granules can not be mixed with PVA. Adding other plastics, such as PE, can be made by granulation first. According to the experts, the process flow of solution casting is relatively simple, but the quality of the product is not easy to be controlled, the film rate is low, the energy consumption is high, and the investment of the equipment is great, and the extrusion blow film method is obviously better than the casting method in the product quality and production efficiency.
With the rapid development of Industrial Science and technology, the film blowing machine is widely used in all kinds of packaging production industries, such as food and clothing. The reform and innovation of the manufacturing technology of the film blowing machine will promote the safety and rapid development of the plastic industry. For a long time, the technology of plastic production equipment in China has been to a certain extent since its introduction and development. Relying on foreign advanced machinery and equipment and importing foreign technology will increase the production cost of plastic industry and plastic machinery industry.
Now the packaging is an indispensable part of the product. At present, the popular packaging in the market is mainly plastic and paper. The blow molding industry with the main blow blowing machine has a larger proportion in the market. However, as the demand for the paper industry is more and more strict, the new index of environmental protection and energy saving has raised the threshold of the paper making industry, resulting in the paper packaging market. The cost of the field is expanding and the price is rising.
In the new economic development, commercialization is an important feature of product production and processing. In the business competition, the quality and the environmental protection are the first factors to be considered. The mechanical manufacturing industry of the film blowing machine applies the high-tech, the new type of film blowing machine produced is not only adapted to the diversified demand of the market, but also the advanced technology promotes the energy saving and emission reduction in the production process, which not only brings economic benefits, but also increases the social efficiency. Benefit.
