Through screening, splitting, high temperature treatment, bleaching, chemical treatment, neutralization and screening, the fibers are divided into different length and fineness to meet the needs of different application materials. Because the temperature above 260 degrees under normal conditions are very stable chemical substances, no corrosion and general solvent, acid and alkali, we use natural raw materials for the production of lignin fiber has excellent quality, non-toxic tasteless, no pollution, no radiation, is green environmental protection products, this is the other mineral fibers do not have the impact on the environment, it is harmless to the human body, is conducive to environmental protection. The role of lignin fiber in building materials: Wood fiber is easy to disperse in the insulation material to form three-dimensional space results, and can absorb 6-8 times the weight of moisture. The operation performance of the node and the characteristics of improved material and easy performance, anti slip performance, speed up the construction of wood fiber; dimensional stability and thermal stability of the insulation material has played a good role in insulating crack; water transfer function of wood fiber to make the slurry surface and the grass-roots level interface adequate hydration, in order to improve the uniformity of surface strength, thermal insulation material and the bonding strength and material strength. These properties make wood fiber become an indispensable additive in thermal insulation materials. 1. strong thickening enhancement effect: Lignocelluloses crosslinked with darn strong function, it is mixed with other materials fiber lap into three-dimensional structure of water can be locked in the meantime to alleviate the condensate water to effectively reduce the water crack. 2. improve operating performance: When the shear acts on it (such as stirring, pumping), some liquid will be thrown from the fiber structure to the matrix When the flow stops, the fiber structure recovers very quickly and absorbs moisture and restores the original viscosity. 3. crack resistance: The mechanical energy produced during solidification or drying is weakened by fiber reinforcement to prevent crazing. 4. low shrinkage: The biological size stability of wood fiber is very good, the mixture will not shrink settlement, and improve its crack resistance. 5. good liquid coercive force: Wood fiber itself can absorb 6-8 times the weight of the liquid, and use its structure to absorb 6-10 times of liquid. 6. anti falling: Construction operation and drying process will not fall phenomenon. This allows thicker plaster to be finished once, even under high temperature conditions 7. Easy to disperse: The wood fiber also has good thermal stability. Mixing with other materials is easy, uniform dispersion, good leveling, no hanging, splash resistance. The role of lignocellulose in thermal insulation materials: Lignocellulose is easy to disperse in the insulation material to form three-dimensional results, and can absorb 2-6 times the moisture of the weight. This structure and characteristics improve the material's ease and performance, operation performance, anti slide performance, and accelerate the construction speed; Lignocellulose dimensional stability and thermal stability in insulation material has played a good role in insulating crack; water transfer function of lignocellulose, make the slurry surface and the grass-roots level interface adequate hydration, thus improving the uniformity of surface strength of insulation materials and basic bond strength and material strength. These properties make lignocellulose an indispensable additive in thermal insulation materials. Lignin fiber (Methyl Cellulose) Referred to as MC) is the natural wood by chemical treatment of organic fibers. Through screening, splitting, high temperature treatment, bleaching, chemical treatment, neutralization and screening, the fibers are divided into different length and fineness to meet the needs of different application materials. Because the temperature up to 260 DEG C under normal conditions is very stable chemical substances, not as a general solvent, acid, alkali corrosion. We use natural raw materials for the production of lignin fibers is environment-friendly, does not affect the environment, untreated lignin fiber is also used as a food additive. Diet food, so harmless to the human body, is conducive to environmental protection, do not cause pollution. Application of lignin fiber in building engineering: Cement based plastering mortar: The improvement of uniformity, the mortar coating more easily, and improve the anti slip ability. Enhance liquidity and pumping, so as to improve work efficiency. The high water retention and prolong work time of mortar, improve work efficiency, and helps the formation of mortar with high mechanical strength during solidification. The control of air infiltration, thereby eliminating the micro cracks formed on the surface of coating, smooth ideal. Building waterproof: The fiber mortar can effectively solve the technical performance defect structure self waterproofing, roofing and other modern engineering technology innovation and application development. Tile adhesive: The use of dry mixture easy to mix, no mass, can improve the workability and reduce the cost. By prolonged cooling time, improve the efficiency of the brick post. Good adhesion effect. Self leveling floor material: It can improve the viscosity, and anti settling agent. The increasing liquidity and pumpability, so as to improve the efficiency of the shop floor. The control of the water, thus greatly reducing the cracking and shrinkage. Masonry mortar: The enhancement and adhesion to the surface of the masonry. It can enhance the security of water, so that mortar strength can be improved. We improve the lubricity and plasticity, thus improve the performance of construction, easy application, save time and improve cost efficiency. Excellent water retention, low dosage, suitable for cement body Department. Caulking agent: The excellent water retention, can prolong cooling time and improve work efficiency. 高润滑性，使施用更容易、平顺。 We improve the anti shrinkage and cracking resistance, improve the surface quality. It provides smooth and uniform texture, and stronger surface adhesion of the bonding. For mortar: The fiber mortar made of fiber into mortar is superior to ordinary mortar. It can increase the tensile strength of mortar and disperse the shrinkage pressure. It can effectively overcome the cracks and seepage problems of the wall. At the same time, the site plastering operation is good, the mortar is not easy to scatter, and the overall sense of paint is no obvious abnormality. Sprayed concrete: It can form a thick layer of sprayed concrete. It has a higher viscosity. The jet jet concrete the initial velocity is only the use of other materials when 70% - 80%, The rebound loss of sprayed concrete is reduced, the strength of concrete is increased, and the rebound loss of concrete is reduced. Gypsum based plastering mortar and gypsum products: The improvement of uniformity, the mortar coating more easily, and improve the anti dropping capability. Enhance liquidity and pumping, so as to improve work efficiency. The high water retention and prolong work time of mortar, and the formation of high mechanical strength during solidification. By uniform consistency control mortar, forming surface coating quality. Used in paint coatings and asphalt materials: High temperature stability and the improvement of asphalt pavement, fatigue durability. It has strong anti cracking and reduce the performance of preventing reflection cracks, improve the tensile strength, crack resistance, resistance. Wall mortar surface layer: The fiber mortar used in wall surface, which can effectively prevent the wall cracking phenomenon, achieve the effect of anti seepage. The fiber cement mortar has good operating characteristics of the construction of dressing. It has no effect on the appearance of mortar surface. The technical defects of fiber can make up the new lightweight wall material. The surface layer of different degrees of cracking and permeability defects of inadequate performance of the existence of all kinds of light energy-saving wall materials, the effect of its application, in the use of these wall materials at the same time, supporting the use of peer as the fiber mortar plastering surface layer, can fully compensate for the defects, is beneficial to improve the quality of the project. Thermal insulation mortar base course: The fiber mortar plastering mortar base make scraping greasy layer neat, beautiful smooth, suitable for all kinds of architectural coatings. Engineering application of various coatings widely, put forward higher requirements for building mortar, mortar due to its good crack resistance, frost resistance, improve its engineering properties can meet the requirements of the right to the construction process and ensure the quality of construction fundamentally. We improve the efficiency and reduce the loss of plastering construction. Because of its fiber mortar bonding and stability are better than the net cement mortar, plastering construction on a drop of easy ash mortar is greatly reduced, can improve the efficiency and reduce the loss of material plastering. It is beneficial to ensure the construction quality of tile surface layer. The fiber mortar base, due to the cracking phenomenon reduced or disappeared, to ensure tile with strength, prevent brick cracking and hollowing phenomenon, plays an extremely important role [this post has been edited by greenme in 2005-4-16 11:41:27] -- -- -- Hi tech BBS thank you for your support!.....
