Problems solved by technology

[0004] Due to the burning of straw, the concentration of soot, particulate matter and other pollutants in the air increases sharply, and the air quality declines rapidly, which is not conducive to human health
The second is to reduce the visibility of the atmosphere, obstruct traffic, and burn straws for cooking and heating in daily life, which also seriously pollutes the environment.

Embodiment Construction

[0028] Below in conjunction with embodiment the present invention will be further described:

[0029] 1. The acidified straw ingredients are composed of the following components by weight percentage: acidified straw semi-finished products 96%, instant sodium silicate 2%, polyvinyl alcohol 1.5%, hydroxypropyl methylcellulose 0.49% and sodium carbonate 0.01 %.

[0030] 2. The production method of the acidified straw: input the acidified straw ingredients into a mill for grinding, the particle fineness is ≤0.074 mm, and the powder after grinding is the finished product of the acidified straw.

[0031] 3. The production method of acidified straw semi-finished products: ⑴ input the straw mixture into the running mixer and stir, then slowly add dilute sulfuric acid into the straw mixture for acidification treatment; ⑵ pass the acidified straw mixture through the roller machine Extruded into straw flakes, the thickness of the straw flakes is less than or equal to 3mm; (3) The straw ...

Abstract

The invention discloses an acidified straw. The main point of the technical scheme is that the acidified straw ingredients are composed of straw, attapulgite clay, magnesium oxide, sulfuric acid, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methyl Composed of cellulose and sodium carbonate. The acidified straw ingredients are input into a mill for grinding, and the powder after grinding is the acidified straw. The production method of the acidified straw can avoid the chemical reaction between sulfuric acid and instant sodium silicate, polyvinyl alcohol, hydroxypropyl methylcellulose and sodium carbonate; the straw is a new product that has been carbonized after being acidified and roasted. The utilization rate of the straw can be improved, not only can bring good economic benefits, environmental benefits and social benefits, but also can realize turning waste into wealth. It has the characteristics of good adsorption, thixotropy, thermal stability, plasticity, cohesiveness and high dry compressive strength. The acidified straw is suitable for the production of environmental protection materials, garden materials, building materials and foaming agent products.

Description

technical field [0001] The invention relates to acidification treatment, in particular to an acidified straw. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops, and usually refers to the remaining parts of wheat, rice, corn, potatoes, oilseeds, cotton, sugar cane and other crops after harvesting seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a multi-purpose renewable biological resource. [0003] Except for a small amount of straw used for gaskets, feeding livestock, and some used for composting, most of them were burned as fuel. [0004] Due to the burning of straw, the concentration of soot, particulate matter and other pollutants in the air increases sharply, and the air quality declines rapidly, which is not conducive to human health. The second is to reduce the visibility of the atmosphere,...
