A kind of anticorrosion treatment process of sorghum straw

Abstract

The invention discloses an anti-corrosion treatment process for sorghum straw. The anti-corrosion treatment process comprises the following steps of (1) straw pretreatment, (2) straw bundle preparation, (3) treatment solution preparation, (4) modification drying treatment, and (5) weaving. Drying and anti-corrosion modification on sorghum straw are carried out simultaneously, and different from the traditional mode that drying, modification and drying are carried out sequentially, through the unique and efficient drying mode, the overall energy consumption can be lowered by 35-45%; various prepared treatment solutions are complete in function, the drying method accords with the drying rule of sorghum straw, and finally obtained woven sorghum straw products are excellent and stable in mechanical property such as flexibility and strength, and are protected against mildew, moths and the like within eight years under normal using conditions; and the loss ratio of sorghum straw in the processing flow is lowered to 3% or below, and good economic benefits are achieved.

Description

technical field [0001] The invention relates to a process for treating sorghum stalks, in particular to an antiseptic treatment process for sorghum stalks. Background technique [0002] Sorghum stalks are wastes left after harvesting sorghum. Initially, people disposed of them by burning them and returning them to the fields, but this method was gradually abandoned due to the great harm to the environment. People try to develop and utilize sorghum stalks without pollution, and they are currently used to make fertilizers, biochemical raw materials, clean fuels, and weaving. With the improvement of people's love for weaving products, more and more sorghum straws are used for weaving. The weaving products made have good use value and can create good economic value. One of the more efficient methods. [0003] Due to its own characteristics, sorghum stalks usually need to be treated with anti-corrosion to improve their service life when weaving and reusing. Drying is also an es...

AI Technical Summary

Problems solved by technology

In the existing method, the sorghum stalks are usually pre-dried first, cooled to normal temperature, and then subjected to anti-corrosion treatment. Finally, it needs to be dried, which requires multiple times of drying, which wastes more heat and more losses. The final treated sorghum straw woven fabrics have poor anti-corrosion effect, uneven strength, easy cracking, and poor flexibility. The loss rate of sorghum straw due to the process is over 10%, and the economic benefit is poor.
