[technique] wood fiber is useful in construction. How can wood fiber be prepared well?

Release date:2016-04-23 Source:

A lot of people for the understanding of the wood fiber is very limited, but today we put this and steel fiber, wood fiber, RPC special effect which embedding, do good, how much money, cost, and so on the problems such as plastic are put down, look at the wood fiber in building on the use of wood fiber to do the pretreatment, I hope you can understand more

 [skills] wood fiber use wood fiber pretreatment in the construction of how to do

We admired the wood fiber is a green environmental protection product, with the pace of social development continues to accelerate, we constantly improve the product requirements of environmental protection. Therefore, in the development of the construction industry, the effect of wood fiber is still very large, we work together to do a simple understanding.

The transmission function of wood fiber moisture to make the slurry surface and the grass-roots level interface adequate hydration, thus improving the uniformity of surface strength, thermal insulation material and the bonding strength and material strength. Become one of the most important additive for building insulation materials added.

Wood fiber in building materials, coatings, insulation mortar wood, wood fiber in building useful brick binder, caulking gypsum, latex paint, paint the relief pattern has the ease water anti cracking, sagging and other functions. The wood fiber has the advantages of better performance, enhanced absorption effect is more obvious and easy to disperse etc..

An important feature is the use of renewable wood fiber, we can preprocess the operation, reuse can achieve energy, reduces production cost. The wood fiber pretreatment is a process of transformation, we usually by several methods to achieve.

Chemical method: using various chemical reagents (including water) of lignocellulose pretreatment methods to improve the efficiency of cellulase hydrolysis. At present, the chemical method is still the main method of cellulose pretreatment process.

Physical method: mainly through the method of physical machinery such as milling and grinding and other traditional processing methods to reduce the fineness and increasing the specific surface of wood fiber to fiber pretreatment product, in addition to ultrasonic irradiation pretreatment methods, to change the structure of cellulose, cellulose enzyme catalysis is easy to.

The physical and chemical method: a combination of chemical and physical and mechanical (suddenly bring pressure relief blasting force) effect will destroy the cell wall structure of raw materials, improve the cellulose accessibility method.

Biological method: commonly used in lignocellulose pretreatment is mainly conducted in nature that can degrade lignin microorganisms, mainly fungi (such as white rot, brown rot and soft rot), which can effectively promote the enzyme degradation of lignin, the subsequent hydrolysis reaction.

According to this article, we believe that the use of wood fiber wood fiber to do pretreatment "have a certain understanding on the building, if you want to know Special steel fiber RPC The effect of wood fiber and other related knowledge, please contact us!
