Latest company news about Introduction And Use Of Coated Fiberglass Fabric

    Coated fiberglass fabric, which is a fiberglass cloth coated with a fireproof coating on the surface of glass fiber cloth, is generally used in the fields of thermal insulation, heat insulation and fire protection. Glass fiber is an inorganic non-metallic material with excellent performance. It has many advantages, such as fireproof and non-combustible, strong heat resistance, good thermal insulation, good corrosion resistance, high mechanical strength, etc., Glass fiber can be made into products of different shapes such as cloth, felt, belt, rope, tape, sleeving, etc. But it also has shortcomings, mainly brittleness and poor abrasion resistance. Fiberglass fabric is made of high-temperature solutes of raw materials such as limestone, pyrophyllite, quartz stone, etc., through drawing, winding, weaving and other processes. Its monofilament diameter is 3 to 20 microns, which is equivalent to 1/20 of a human hair. , Each strand of glass fiber strands is composed of hundreds of monofilaments.


    In order to overcome the shortcomings of the fiberglass fabric itself, the fiberglass fabric manufacturer came up with a fireproof coating on its surface, which can overcome the glass fiber cloth's non-abrasion resistance, non-bending resistance, and easy fraying during the cutting process. And it can also reduce the irritation of glass fiber to the skin. Combining high molecular polymers to glass fiber cloth through a professional coating process can eliminate or reduce many shortcomings of glass fiber cloth. Common polymer coatings include silicone rubber coating, polyurethane coating, acrylic coating, ptfe coating, neoprene coating, hypalon coating, common high temperature coatings are vermiculite coating, graphite coating , calcium silicate coating, bentonite coating, etc. The temperature resistance range of these coated glass fiber cloths is about -70 degrees Celsius to 1200 degrees Celsius, and the thickness is about 0.1 mm to 6 mm. Common composites are aluminum foil and so on. The properties of the coating material (polymer or aluminum foil) (such as waterproof, abrasion resistance, oil resistance, corrosion resistance, weather resistance, heat reflection, good sealing, easily for fabrication and sewn, etc.) and glass fiber properties (fire resistance, heat insulation, high strength, etc.) combined together to form a new composite material, which can provide a wider range of functions. These coated fiberglass fabrics have a wide range of uses, such as fire curtains, smoke curtains, fire curtains for furnace doors of smelting furnaces, fire curtains for oil platforms, removable insulation jacket, exhaust pipe insulation Covers, fire blankets, welding blankets, battery fireproof bags, fireproof file bags, fireproof mats, welding protective mats, fabric air distribution ducts, flexible duct connector, industrial smoke exhaust pipe soft connections, fabric expansion joint, outdoor tent chimney heat insulation and anti-scalding mat, steel mill steel waterwheel cable protection sleeve, pipe insulation outer protective layer, HVAC system pipe fire protection, robot spot welding robot arm protection cover, fireplace inner frame heat insulation, fireproof decoration materials , high temperature resistant electrical tape, floating roof of petroleum storage tank, etc. Fiberglass fabric coating (including composite) processes generally include blade coating, dipping, roll coating, calendering, and composite processes. The coated fiberglass fabric made by each process may have some differences in performance, so you must decide which fiberglass fabric coating process and which coating to choose, according to the performance requirements of your actual application.
