Embodiment 1

[0020] A specific embodiment of the method for making fireproof MDF with mulberry branches according to the present invention, the method may further comprise the steps:

[0021] 1. Mulberry branch crushing: The particle size of the mulberry branch after crushing is required to be 0.1-5mm. The particle size should not be too large or too small. Too large particle size will affect the uniformity of the board quality. Some tensile strength. It is advisable that the particle water content of the pulverized mulberry branch is less than 27%.

[0022] 2. Ingredients: mix mulberry powder with magnesia cement, perlite, talcum powder or quartz powder according to the mass ratio of 1:5:0.1:0.3, and mix and use now. Note that when adding fillers, lime powder and light calcium and other substances cannot be added.

[0023] 3. Stirring and beating: Put the prepared materials into the mixer, add coagulant for stirring and beating, when the temperature is lower than 20°C, it can be thicker...

Embodiment 2

[0031] Another specific embodiment of the method of using mulberry branches to manufacture fireproof MDF according to the present invention, this embodiment is the same as embodiment 1 except that the proportioning of ingredients is different.

[0032] Ingredients: the mulberry branch powder is mixed with magnesia cement, perlite, talc powder or quartz powder according to the mass ratio of 1.5:8:0.1:0.3, and it is prepared and used immediately. Note that when adding fillers, lime powder and light calcium and other substances cannot be added.

[0033] By adopting the above-mentioned technological process, fireproof MDF boards of various specifications can be produced with mulberry branches.

Embodiment 3

[0035] Another specific embodiment of the method of using mulberry branches to manufacture fireproof MDF according to the present invention, this embodiment is the same as embodiment 1 except that the proportioning of ingredients is different.

[0036] Ingredients: mix mulberry powder with magnesia cement, perlite, talcum powder or quartz powder according to the mass ratio of 1.2:7:0.1:0.3, and mix and use immediately. Note that when adding fillers, lime powder and light calcium and other substances cannot be added.

[0037] By adopting the above-mentioned technological process, fireproof MDF boards of various specifications can be produced with mulberry branches.

Abstract

The invention relates to a method for manufacturing fireproof density plates by using mulberry branches, which comprises the following steps of: crushing the mulberry branches, mixing the crushed mulberry branches with magnesium-oxygen cement, pearlite, talcum powder or quartz powder according to the mass ratio of 1-2:5-8:0.1:0.3, adding a coagulating agent, stirring and beating to form slurry, quickly placing the slurry into a roll squeezer for rolling, solidifying for sizing, demoulding, cutting according to a target specification, leveling up for maintaining for 5-8 days, placing in water to soak for 6-10 hours, taking out, drying in the sun or by air, cutting according to target specification, classifying and checking. In the invention, the mulberry branches as agricultural wastes are sufficiently utilized to produce the fireproof density plates, coal is not burnt in the production process, and soot and sewage are not discharged, thereby the purposes of comprehensively utilizing resources, turning waste into wealth and protecting the ecology and the environment are achieved.

Description

technical field [0001] The invention relates to a method for manufacturing density boards, in particular to a method for manufacturing fireproof density boards with mulberry branches. Background technique [0002] China is a big agricultural country, and it is also a big silkworm producing country, with more than 30 million tons of mulberry branches cut down every year. The prospect of developing mulberry wood-based panels in China is broad. At the same time, my country is a developing country with a large population and severe shortage of forest resources. The forest coverage rate is 18.21%, and the per capita forest resource ownership rate is less than one-tenth of the world's average level. With the rapid development of the national economy and the rapid improvement of people's quality of life, the demand for timber has become one of the most scarce resources in our country. [0003] At present, there is no report on the research on the development of mulberry boards ab...
