Abstract
The production process of densified straw board incldues: sorting plant straw; cutting; digestion; crushing; stoving; mixing with adhesive while stirring; and stoving to form. By using straw as waste material as raw material, the present invention can eliminate environmental pollution caused by incineration and piling of straw while making densified and high-strength board. The produced board has round corners for facilitating use and transport.
Description
The present invention relates to a kind of vegetable fibre board and manufacture method thereof, particularly a kind of densified straw board and manufacture method thereof.
At present, the method that adopts string to make density board mostly is thin ligneous plant stalk manufacturings such as adopting sunflower pole, soybean straw, eggplant bar, waste of flax, straw, and need add additives such as anti-blushing agent, curing agent, manufacturing process complexity when making.
The objective of the invention is to: a kind of densified straw board and manufacture method thereof are provided, and are raw material with wherein one or more of the cornstalk that reclaims, rice bar, wheat straw, the product densification, and the intensity height, manufacturing process is simple.
The present invention is achieved in that a kind of manufacture method of densified straw board, 1. selected straw; 2. cut off; 3. with stalk 150 ℃ of following boilings more than 1 hour; 4. stalk is broken into pigment and is the particle of particle diameter less than 3mm; 5. oven dry; 6. adding weight in the stalk fibre particle is the glue of stalk fibre particle weight 25%-35%; 7. fully stir; 8. pressurizeing more than 200 kilograms bake pressure, moulding on the bake pressure machine.
The weight of described glue is stalk fibre particle weight 20%.
The manufacture method of described glue is: formaldehyde is heated after 30 ℃, after adding weight is the urea of formaldehyde weight 40%, heat and add caustic soda to 60 ℃ and make the pH value be adjusted into the 7.5-8.0 scope, add ammonium chloride again and make the pH value be adjusted into the 5.1-4.8 scope, the urea that adds weight at last and be formaldehyde weight 11% gets final product.
A kind of densified straw board made from said method, four jiaos of plate is circular arc.
The present invention has solved crop straw burning and has stacked the problem of environmental pollution that causes owing to utilized agricultural stalk class discarded object as raw material, and the manufactured goods densification, the intensity height, and manufacturing process is simple; Manufactured goods are that circular arc can make things convenient for using and transporting of sheet material for four jiaos.
The present invention will be further described below in conjunction with embodiment.
100 kilograms of the 1. selected cornstalks of embodiment 1.; 2. cut off; 3. with stalk 1502 times boilings more than 1 hour; 4. stalk is broken into pigment and is the particle of particle diameter less than 3mm; 5. oven dry; 6. in the stalk fibre particle, add weight and be 25 kilograms glue; 7. fully stir; 8. pressurizeing more than 200 kilograms bake pressure, moulding on the bake pressure machine.The manufacture method of described glue is: 50 kilograms of formaldehyde are heated after 30 ℃, after adding 20 kilograms of urea of weight, heating adds caustic soda to 60 ℃ and makes the pH value be adjusted into the 7.5-8.0 scope, adds ammonium chloride again and makes the pH value be adjusted into the 5.1-4.8 scope, and the urea that adds 5.5 kilograms of weight at last gets final product.
Embodiment 2. selects the rice bar according to the method for embodiment 1, with 35 kilograms in glue.
Embodiment 3. selects totally 100 kilograms on wheat straw and rice bar according to the method for embodiment 1, with 20 kilograms in glue.
Claims (5)
1. the manufacture method of a densified straw board, 1. selected straw; 2. cut off; 3. with stalk 150 ℃ of following boilings more than 1 hour; 4. stalk is broken into pigment and is the particle of particle diameter less than 3mm; 5. oven dry; 6. adding weight in the stalk fibre particle is the glue of stalk fibre particle weight 25%-35%; 7. fully stir; 8. pressurizeing more than 200 kilograms moulding on the bake pressure machine.
2. the manufacture method of densified straw board according to claim 1, described straw are wherein one or more of cornstalk, rice bar, wheat straw.
3. the manufacture method of densified straw board according to claim 1 and 2, the weight of described glue is stalk fibre particle weight 20%.
4. the manufacture method of densified straw board according to claim 1 and 2, the manufacture method of described glue is: formaldehyde is heated after 30 ℃, after adding weight is the urea of formaldehyde weight 40%, heat and add caustic soda to 60 ℃ and make the pH value be adjusted into the 7.5-8.0 scope, add ammonium chloride again and make the pH value be adjusted into the 5.1-4.8 scope, the urea that adds weight at last and be formaldehyde weight 11% gets final product.
5. densified straw board made from the described method of claim 1, it is characterized in that: four jiaos of plate is circular arc.
