The pulp molding product is an environment-friendly product recommended by the world environment protection department, and the environment-friendly work is very important in the production process, so that the influence of three waste problems on the environment is caused, the environment-friendly consciousness is very strong from the used main raw materials to the end of the whole production process in the whole production process, the raw materials are waste paper, the physical reaction is mainly adopted in the production and processing process, only a small amount of chemical products are added as a waterproof agent, and the chemical products are basically and completely remained in the finished product after the product is dried and are not discharged to cause the environmental pollution; the water used in the production line is used in a closed cycle, only the water vapor generated in the product drying process is volatilized to the space, and the water does not need to be supplemented in the production process, so the water consumption is not large.
The paper pulp molding technology is developed and innovated for years, the performance of equipment is continuously improved, the production process is gradually mature, the production cost of products is driven to be stable, the production cost of domestic paper support products is basically equal to that of foam plastic products at present, the cost of some paper support products is obviously lower than that of the foam plastic products, the paper support products replace foam plastic shockproof products, feasibility is realized in the service performance and the production cost, and the paper pulp molding products replace the foam plastic products in addition to the advantages of the paper pulp molding technology in the aspect of environmental protection, so that the paper pulp molding technology has a necessary trend.
The pulping process of the paper pulp molding product comprises the following steps: the paper is made into fiber by using raw pulp paper boards, waste paper, paper boxes and the like as raw materials through processes of pulping, jordaning and the like, and is suspended in water to form paper pulp. According to the characteristics of the products to be produced, the fiber length and the pulp concentration can be properly controlled to meet the requirements of the products, and special auxiliaries are added into the pulp to enable the products to have the functions of water resistance, oil resistance and the like. The product can be made into various colors by adding proper pigment.
The forming process of the paper pulp molded product adopted by the invention is a vacuum pulp-sucking forming method, which is the most popular method of the paper-plastic product and has three modes according to different structures: drum type, turnover type, reciprocating lifting type;
and (3) drum type: the continuous rotary production has the advantages of high production efficiency, large mold investment, high mold processing precision and high technical requirement on equipment processing precision, one set of female mold is matched with eight sets of male molds, a numerical control center is required for processing the molds, the processing period is long, the investment is high, the continuous production is suitable for large-batch production of shaped products such as fruit trays, dinner plates, wine trays and egg trays, and the industrial molding production is not suitable for non-standard production, small quantity and batch production and large mold investment.
Turning: the return production has lower production efficiency than the drum production, and is suitable for the medium-batch and nonstandard production of industrial molding, but because one set of female die is matched with two sets of male dies, a numerical control center is required to process the dies, the die investment is large, and the period is long.
A reciprocating lifting type: the production efficiency is lower than that of a rotary drum type, the difference between the production efficiency and the rotary drum type is not large, the equipment is common equipment used in normal wind at present, only one female die is matched with one male die, numerical control center processing is not needed, and the equipment is particularly suitable for non-standard industrial packaging products with small batches and fast period.
The drying process of the paper pulp molding product comprises the following steps: after pulp crushing and forming, the paper pulp products generally contain higher moisture, and a drying process is needed, wherein the drying process uses fuel oil (gas), electricity or steam, hot oil or other media as heat sources to heat air, the formed paper pulp molding products are dried in hot air (180-220 ℃), and a fan is used for pumping out the moisture evaporated from the products, so that the effect of quick drying is achieved.
The shaping process of the paper pulp molding product comprises the following steps: the paper pulp product is basically shaped after being formed and dried, and then is pressed at high temperature and high pressure, so that the paper pulp product is neat and attractive in appearance, achieves better toughness and better shock resistance, and the shaping process generally heats the heating plate by an electric heating plate or other heat media (such as heat conduction oil), so that a paper pulp product mold has higher temperature (180-250 ℃), and presses the paper support product at high temperature and high pressure by using air pressure or hydraulic pressure, thereby achieving the shaping effect.
According to the invention, waste materials such as waste paper and waste package are used as raw materials, and the raw materials are made into fiber paper pulp for manufacturing the dust collecting box, so that the functions of wide raw material source, greatly lower cost than the existing plastic dust collecting box manufacturing process, complete degradation of the dust collecting box, environmental protection and convenience are realized.
