Introduction to lignocellulose
Lignocellulose is an organic flocculent fibrous material obtained from natural renewable wood through chemical treatment and mechanical processing. Non-toxic, odorless, non-polluting, non-radioactive, with excellent flexibility and dispersibility. Lignocellulose is insoluble in water, weak acid and alkaline solutions, and has a neutral pH value, which can improve the corrosion resistance of the rubber compound. Lignocellulose has a small specific gravity and a large specific surface area. It has excellent thermal insulation, heat insulation, sound insulation, insulation and air permeability. When the working temperature of the product reaches 150 °C, it can be insulated for several days, when it reaches 200 °C, it can be insulated for dozens of hours, and it can be insulated for several hours when it exceeds 220 °C. Lignocellulosic cords can also be used as thickeners, absorbents, diluents or as carriers and fillers.
It is an organic flocculent fibrous substance obtained by chemical treatment and mechanical processing of natural renewable wood, which is non-toxic, odorless, non-polluting and non-radioactive. Widely used in concrete mortar, gypsum products, wood pulp sponge, asphalt roads and other fields, to prevent coating cracking, improve water retention, improve production stability and construction suitability, increase strength, enhance adhesion to the surface, etc. There are good results. Its technical functions are mainly: thixotropy, protection, absorption, carrier and filler.
Due to the capillary action of the fiber structure, the moisture inside the system is rapidly transported to the surface and interface of the slurry, which makes the moisture distribution inside the slurry uniform and significantly reduces the skinning phenomenon. And make the bond strength and surface strength significantly improved, this mechanism also plays a significant role in crack resistance due to the reduction of tension in the drying process. The dimensional stability and thermal stability of lignocellulose play a good role in thermal insulation and crack resistance in thermal insulation materials.
