Straw-woven imitation cotton is made of fresh straw as the main raw material and new chemical raw materials through more than ten production processes. It can not only produce white and soft imitation cotton, but also produce colored cotton with different colors. The produced imitation cotton has the characteristics of good elasticity, strong warmth retention, fluffy and light weight, and can be comparable to natural cotton in water absorption, specific gravity and whiteness. It has two major selling points: one is waste utilization. Imitation cotton made of straw not only solves the problem of straw waste, but also produces new products with greater value, killing two birds with one stone. Second, the cost is low. The cost of artificial cotton made of straw is lower than that of natural cotton. At present, the price per kilogram of natural cotton wool is about 15 yuan, while the price per kilogram of artificial cotton in 2 yuan is about 15 yuan. Compared with other fillers, artificial cotton is superior to other textile fillers in softness and elasticity because of its disinfection and sterilization effect. Although the cost is slightly higher, it has a competitive advantage in cost performance.
2. Straw fiberboard has a wide range of uses, and can be used to make various high-grade packaging boxes, house decoration and furniture industries, with broad development prospects. It is made of rice straw as the main raw material through pretreatment, alkalization, neutralization and extraction, mixing and stirring with resin glue and magnesium oxide in a proper proportion, spreading into blocks with high-temperature oil pressure, cutting and other steps. The product produced by this method has low cost, good fireproof and moisture-proof performance, strong acid and alkali resistance and wide application range. They can be used not only as building decorative boards, but also in furniture production, with little harm to human body. Hollow straw board: it is a hollow board made of cement binder mixture made of cement, rice straw, sodium fluorosilicate, sodium silicate urea-formaldehyde resin and white latex, and then mixed with rice straw to make slurry. Its load can be comparable to the existing ordinary hollow cement board, so it can completely replace the ordinary hollow cement board and be used for floors and other building boards. This is a new building board.
The preparation process of rice straw (or wheat straw) board: cut rice straw or wheat straw into 30- 120 m/m length, lay it flat on the board making machine, and spray a new layer of adhesive. Adhesives for ordinary boards are mainly formaldehyde, urea and cement, and adhesives for waterproof boards are mainly sodium silicate, petroleum asphalt, waste rubber, plastics and blood powder. The manufactured board meets the requirements of national standards for wood chips. Suitable for interior walls, partition boards and floors, roofs, underground warehouses, etc. Preparation technology of plant fiber-based panel: The existing straw-based panel has the disadvantages of low strength and unevenness due to raw material composition and process problems. According to the invention, shredded rice straw is used as a base material, urea-formaldehyde resin is used as an adhesive, urea-formaldehyde resin curing agent is used as a tackifier, and magnesium stearate is used as a toughening agent, so that the invention has certain strength, and has the characteristics of good flatness and good flame retardancy. It is a widely used building and industrial plate with obvious energy-saving effect.
Production method of reinforced straw board: The straw board manufactured by this method does not directly use scattered straw as processing raw materials, but first makes scattered straw into ropes and curtains, then presses the ropes and curtains into plates, heats them to form a board core, and then covers, strengthens decoration, cools, cuts and seals them to make products (see the attached figure of the abstract). The straw board produced by this method has smooth and uniform feeding, compact structure and continuous longitudinal and transverse fibers, and its strength, especially the longitudinal strength, is greatly improved. Better than pressing straw board, comparable to wood, sound insulation and fire prevention is better than wood. It can be used as fire doors, partitions, ceilings and roofs, and can also be used as train carriages, packaging boxes and furniture. Rich raw materials, simple method and remarkable economic and social benefits are suitable for building factories in towns and counties.
3. Brew sweet beer. The chopped wheat straw is added with a certain amount of water and biological agents, fermented at a certain temperature for a certain period of time, and the fermented liquid is filtered after detection. Then precipitate, filter out the precipitate, sterilize at high temperature, and add a small amount of hops and baking soda to make sweet beer containing 5% alcohol, 10% fructose, glucose and various amino acids. This kind of beer contains very little sodium lignosulfonate, so it has the effect of lowering blood pressure.
4. Brewing without grain. If the wheat straw is deeply fermented and the fermented product is distilled, 60% liquor can be obtained by 30 ~ 50 kg (per ton of raw materials). This project is "Brewing without Grain".
5. Bio-manufacturing pulp. The solid and waste after making beer and liquor are piled up for 2-3 days, naturally fermented, and when the temperature rises to 50-60℃, pulped to make yellow board paper. If a small amount of alkali (20-40 kg alkali per ton) is used for cooking, washing and rinsing, bleached pulp can be made. This pulping method fundamentally eliminates the serious pollution caused by chemical pulping, and at the same time improves the strength of paper and reduces the cost (the cost per ton of bleached pulp is 1000 yuan, and the cost of chemical pulping is 3000-4000 yuan).
6. Saccharified pig feed. Wheat straw and rice straw are crushed by a crusher, and a certain amount of water and biological enzyme are added for fermentation. When there is strong alcohol, the liquid is sweet and can be mixed with other pig feed. In this way, the cost of raising pigs can be reduced by 1/2 to 1/3.
7. Processing carbon black

1 1, straw ash or asbestos ash has been used as hot metal covering and slag collecting materials in smelting and pipe casting industries. When casting, the covering area is small, the heat preservation effect is small, and it is easy to pour slag into the mold. Operation is full of dust and pollutes the environment. This product replaces rice straw ash and asbestos ash as insulation materials for pouring ladle and slag collection.
12, used to tie the rope.
13, the straw of late rice is soft, which can be used for feeding cattle, making beds, building straw houses, keeping warm and accelerating germination. After burning ash, it can be hung with alkaline mortar or made into mortar balls, so it has a wide range of uses and is highly valued by farmers.
