Problems solved by technology

Since the fishing net will be impacted by the water flow during use, its strength and aging resistance are particularly important. Most of the fishing nets on the market today are of average strength, and most of the raw materials are synthetic fibers, which do not make good use of renewable resources. , resulting in a waste of resources to a large extent

Embodiment 1

[0030] A kind of method utilizing waste cardboard to prepare fishing net line, comprises the steps:

[0031] (1) Preparation of filler:

[0032] a. Place the recovered waste cardboard in a cryogenic pulverizer for pulverization to obtain powder A for subsequent use;

[0033] b. Place the powder A obtained in operation a in a pyrolysis reactor with an oxygen concentration of 7%, and perform pyrolysis and carbonization treatment. After completion, take out the carbonized particles for later use;

[0034] c. Place the carbonized particles obtained in operation b in the DBD cold plasma device, and the number of times of cold plasma treatment is 4 times;

[0035] d. First mix the carbonized particles and the treatment solution after the cold plasma treatment in operation c according to the weight volume ratio of 1g:100mL and then put them in the reactor. When the temperature rises to 96°C, put the barite powder into the reactor, mix Raise the temperature and increase the pressure...

Abstract

The invention discloses a method for preparing fishing net threads by using waste paperboards, and belongs to the technical field of fishing net processing. The method comprises the following steps of(1) preparing fillers; (2) performing melt spinning; and (3) carrying out stretching and shaping. According to the method for preparing the fishing net threads from the waste paperboards, the waste paperboards are used for fishing net processing, the waste paperboards are fully utilized, cyclic utilization of resources is facilitated, the mechanical property and the anti-aging property of the fishing net are enhanced and improved, the service life of the fishing net is prolonged, the resources are saved to a certain extent, and the 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 fishing net lines 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 recycling statu...
