In China, traditional exterior wall insulation materials, such as polyurethane and other insulation materials, are basically combustible materials. In practice, they are basically unsuccessful and have suffered heavy losses. The basic function of the external wall insulation board is to prevent fire and heat insulation. After practice, the aluminum silicate insulation material has been used to replace the traditional exterior wall insulation material.
Ceramic fiber exterior wall insulation board Features:
1. High compressive strength and long service life
2, easy to cut, easy to install, not easy to break
3, good resistance to wind erosion
4, uniform fiber distribution, stable performance
5, the surface is flat, accurate size
6, uniform structure, good overall
The specific preparation method: taking aluminum silicate fiber, adding inorganic binder, organic binder and additive, fully stirring, mixing and pulping, and then using mechanical extrusion molding or manual molding to produce the garment blank, after 100- Drying at 150 ° C removes moisture and causes the internal binder of the product to gel and harden to a desired hardness. The dried product is cut, ground, and drilled using mechanical equipment for further deep processing.
Compatibility of raw materials: The quality ratio of each component of this product is 40-60 ceramic fiber, 20-30 inorganic binder, 0.5-1.5 organic binder, 20-30 additive.
The ceramic fiber may be made of aluminum silicate fiber of different suitable temperature; the organic binder may be one or a mixture of polyacrylamide, cationic starch or methyl fiber; the inorganic binder is cement, silica sol, One or a mixture of one or more of aluminum sol or sodium silicate; the additive may be one or a mixture of one or more of silica powder, expanded silica powder, expanded perlite powder or silicon micropowder.
Disperse Red series include disperse red F3BS(C.I. Red 343), disperse Red E/R(C.I. Red 50), Disperse red 2B(C.I.Red 13) and disperse red 1 (C.I.Red 1) etc. Disperse Red 343 used for printing and dyeing. Very bright color, high fastness performance is good, easy dyed dark. Its mixed colors with other dyes could replace disperse red 60 in some fibers dyeing and printing.
Disperse Red 50, disperse red 1 and Disperse Red 13 are acetate dyes for acetate fibers dyeing at low energy. These dyes are very popular in Pakistan, Bangladesh, India etc.
