Fiberglass and its fabric surface by coating PTFE, silicone rubber, vermiculite and other modification treatment can improve and enhance the performance of fiberglass and its fabric.
1. PTFE coated on the surface of fiberglass and its fabrics
PTFE has high chemical stability, outstanding non-adhesion, excellent aging resistance, corrosion resistance, self-cleaning and other excellent characteristics, but there are poor mechanical properties, poor wear resistance, poor thermal conductivity and other defects, fiberglass has excellent mechanical properties and physical and chemical properties, fiberglass and its fabric surface coated with PTFE, not only to make up for the defects of PTFE and improve, and also play the advantages of fiberglass performance, and at the same time reduce the fiberglass and its fabrics. Performance, while reducing the brittleness of fiberglass, the formation of high strength, good abrasion resistance, aging-resistant fiberglass / PTFE materials. Fiberglass coated PTFE generally use multiple impregnation process, after heat treatment of fiberglass cloth through the impregnation tank coated with PTFE dispersion, and then drying, baking, sintering and other treatments, the excess water and solvent evaporation of emulsion, leaving PTFE resin particles tightly adhered to the fiberglass cloth, the material has both PTFE characteristics, but also the excellent performance of fiberglass, commonly used as building The material has both PTFE characteristics and excellent performance of fiberglass, and is commonly used as construction materials, insulation materials, friction materials, etc. It is widely used in construction, electronics and other fields.
2. Fiberglass and its fabric surface coated with silicone rubber
Silicone rubber has good electrical insulation, high and low temperature resistance, oxygen aging resistance, etc., in the fiberglass and its fabric surface coated with silicone rubber, can improve the folding performance of fiberglass and wear resistance. Fiberglass and its fabrics as a substrate, coated with silicone rubber to form the coated fiberglass fabrics, with high tensile strength, dimensional stability, good electrical insulation and chemical corrosion resistance and other excellent characteristics, usually as an electrical insulating material, can be made into insulating cloth, casing, etc.; as an anticorrosive material can be used as a pipeline, tanks inside and outside of the anticorrosive layer; but also as a building film, packaging materials, such as in the construction, energy and other industries. It can also be used as construction film and packaging material in construction, energy and other industries.
3. Coating vermiculite on the surface of fiberglass and its fabrics
Vermiculite is a magnesium-containing hydroaluminosilicate mineral that can withstand high temperatures up to 1250°C. After being heated and expanded, its volume increases and its thermal conductivity is low, and the expanded vermiculite has a low density, good chemical insulating properties, heat and sound insulation, and fire and frost resistance. Although the fiberglass has good heat resistance, but the long-term use of the temperature should not be too high, when the open fire flame can even penetrate its products, vermiculite coated in fiberglass and their fabric surface, vermiculite can improve the fire resistance of fiberglass, but also play a role in the effect of fire retardant heat insulation. Vermiculite-coated fiberglass products have higher heat resistance and good heat insulation and flame retardant properties, and are used in welding protection, fire protection, pipe wrapping and so on.
