Problems solved by technology

It can be seen that most of the waste paper recycling in our country is carried out by private individuals to each household. As for the flow of these waste papers, it is also unknown. It can be said that they have solved the accumulation of our own waste paper, but from large On the one hand, it does not fundamentally solve the problem
[0003] And waste paper is recycled repeatedly indefinitely, the limit depends on the deterioration speed and degree of fiber quality. With the increase of waste paper circulation, the physical strength of waste paper pulp shows a linear downward trend. Decreased burst and tensile strength

Embodiment 1

[0029] A method for preparing fillers for fishing net processing by using waste cardboard, comprising the steps of:

[0030] (1) Crushing treatment:

[0031] The recovered waste cardboard is placed in a cryogenic pulverizer for pulverization to obtain powder A for subsequent use;

[0032] (2) Carbonization treatment:

[0033] The powder A obtained in step (1) is placed in a pyrolysis reactor with an oxygen concentration of 7%, and subjected to pyrolysis and carbonization treatment. After completion, the carbonized particles are taken out for later use;

[0034] (3) Cold plasma treatment:

[0035] The charred particulate matter gained in step (2) is placed in the DBD cold plasma device, and the number of times of cold plasma treatment is 4 times;

[0036] (4) High temperature and high pressure treatment:

[0037] Mix the carbonized particles and treatment solution after the cold plasma treatment in step (3) according to the weight volume ratio of 1g:100mL and put them in th...

Abstract

The invention discloses a method for preparing a filler for fishing net processing by using waste paperboards, and belongs to the technical field of fishing net processing. the method comprises the following steps: (1)crushing treatment; (2)carbonizing treatment; (3)cold plasma treatment; (4)high-temperature and high-pressure treatment; and (5)freezing treatment. According to the method for preparing the filler for fishing net processing from the waste paperboards, the waste paperboards are used for fishing net processing, cyclic utilization of resources is facilitated, the mechanical propertyand the ageing resistance of a fishing net are enhanced and improved, the service life of the fishing net is prolonged, the resources are saved to a certain extent, and market popularization and application values are high.

Description

technical field [0001] The invention belongs to the technical field of fishing net processing, in particular to a method for preparing filler for fishing net processing by using waste cardboard. Background technique [0002] my country is the second largest consumer of wood in the world, and its consumption of paper ranks second in the world. It is understood that the annual growth of logs that can be harvested for paper making is insufficient; in addition, due to many ecological problems such as land desertification, soil erosion, floods, and droughts, the desertified land area in my country is continuously expanding, and the overall trend is still worsening. In addition, due to the large demand and use of paper by people, a lot of waste paper cannot be properly disposed of, so that it can be solved by incineration for convenience. Such a result not only fails to solve the problem fundamentally, but also aggravates the pollution of the environment. my country's waste paper...
