Problems solved by technology

[0002] With the development of society and the improvement of people's living standards, the packaging and excessive packaging of various items, as well as office, reading and advertising have produced a huge amount of waste paper, boards and waste plastics, which are discarded as garbage; Valuable resources, but also pollute the air
Moreover, the current industrial and civilian paper consumption has caused the disappearance of large areas of forests, and has greatly deteriorated the climate and environment of the earth on which human beings depend.
Although the grades of industrial and civil waste paper and board are various, the fiber length can still meet the requirements of pulping and papermaking. Although these waste paper, board and waste plastic have lost their high purity, they are still rare raw materials

Embodiment 1

[0009] Example 1, such as figure 1 As shown, a production process of using waste paper, board and waste plastics to make templates, the waste paper and board 1 are pulverized by a shredder 13, purified and pretreated 2, and then pulped 3, and the crushed pulp is passed through Separator 4 sorts, the sorted pulp is concentrated 5 to a concentration of 3.5% and enters the coarse stock pool 6, and the pulp is sent to the refiner 8 through the pulp pump 7, and is ground into a pulp liquid with a knocking degree of 35°SR and a wet weight of 7g , the ground slurry is sent into the slurry tank 9, and then sent into the slurry mixing tank 11 by the slurry pump 10;

[0010] After the waste plastics 12 and the plastics separated by the separator 4 are pulverized by the pulverizer 13, they are sent to the sorting screen 14 for sorting, and the pulverized plastic particles are sent to the grinder 15 for grinding and refining, and the ground plastic sheets and fine particles are passed thr...

Embodiment 2

[0011] Example 2, such as figure 1 As shown, a production process of using waste paper, boards and waste plastics to make templates, the waste paper and boards are pulverized by a shredder 13, purified and pretreated 2, and then pulped 3, and the crushed pulp is separated Classification by the device 4, the classified pulp is concentrated 5 to a concentration of 3.5% and enters the coarse stock pool 6, and the pulp is sent to the refiner 8 through the pulp pump 7, and is ground into a pulp liquid with a knocking degree of 41°SR and a wet weight of 11g. Send the ground slurry into the slurry tank 9, and then send it into the slurry mixing tank 11 through the slurry pump 10;

[0012] After the waste plastics 12 and the plastics separated by the separator 4 are pulverized by the pulverizer 13, they are sent to the sorting screen 14 for sorting, and the pulverized plastic particles are sent to the grinder 15 for grinding and refining, and the ground plastic sheets and fine particl...

Abstract

The invention relates to a process for producing shaping plates by using waste paper, plates and waste plastics. The process includes that subjecting the waste paper and plates to purifying pretreatment prior to pulping; concentrating pulp subjected to size degradation to 4.0+ / -0.5% in concentration before allowing the same to enter a pulp chest, delivering the pulp to a pulping machine through a pulp pump, delivering ground pulp into a full pulp chest prior to delivering the same to a mix pulp chest through the pulp pump; pulverizing the waste plastics through a pulverizer, separating the ground plastic through a separating screen, delivering plastic particles conforming to grinding standard to a grinding machine for grinding and refining prior to delivering to the mix pulp after filamentation; mixing paper pulp and plastic pulp prior to purifying through a slag separator, forming, splitting, drying, cooling, releasing, edge cutting, mechanical processing and finishing, testing, vacuum packaging and vacuum packaging and warehousing. The process is simple in process path, and special equipment can be partially added by utilizing existing equipment, so that equipment investment is less, and commercial value of products is high.

Description

technical field [0001] The invention relates to a production process for making templates with waste paper, boards and waste plastics. Background technique [0002] With the development of society and the improvement of people's living standards, the packaging and excessive packaging of various items and office, reading and advertising have produced a huge amount of waste paper, boards and waste plastics, which are discarded as garbage; Precious resources, but also pollute the air. Moreover, the current industrial and civil paper consumption has caused the disappearance of large areas of forests, and has greatly deteriorated the climate and environment of the earth on which human beings depend. Although the grades of industrial and civil waste paper and board are various, the fiber length can still meet the requirements of pulping and papermaking. Although these waste paper, board and waste plastic have lost their high purity, they are still rare raw materials. Therefore, ...
