Q:What does glass fiber used for?
Glass fiber Glass fiber is a kind of inorganic nonmetal material with excellent performance. English name is: Fiber glass. It is produced by high temperature melting, wire drawing, winding and weaving process with the raw materials of glass balls or waste glass. Glass fiber monofilament diameter ranges from a few microns to twenty micron, the equivalent of a hair 1\20-1\5. Each bundle of fibers are hundreds or even thousands of root root filaments, usually treated as a reinforcing material of complex materials, electrical insulating materials and thermal insulation materials, circuit board, etc. and widely used in various fields of the national economy. Properties of glass fiber: The general concept of glass is hard and brittle objects, but it is not suitable for timber structure as its thread. Strength is greatly increased and it is more flexible, so it can finally become excellent timber structure after shaped by the resin. For glass fiber, with diameter smaller, the intensity increases. As a reinforcing material, glass fiber has the following characteristics. These characteristics make the use of glass fibers more broadly than other species of fibers. Its strength is greatly increased and it is more flexible. With good rigidity, it could absorb more impact energy.
Q:How to make GRC line?
It is different from the cement paste production. Do not deformed in normal temperature or high temperature, pillars of the corridor;
Q:What is rippled glass?
Opaque glass.
Q:What is glass fiber and glass silk?
Q:What type of cement is used in the common GRC component?
Fiber: You can selectively add some of the volcanic ash active material: High efficiency water reducing agent can be selectively added to the water: The basic composition of GRC material is cement: when the product contains steel reinforcement or steel embedded parts of.5%, the low alkalinity sulphoaluminate cement. The acrylate copolymer emulsion, antirust agent and other additives, fiber and water and other additives to improve the performance of the materials later. European and American countries require the use of GRC in the glass fiber zirconia content should be not less than 16, antifreeze, early strength agent, retarder, white Portland cement. . Additive is conducive to improve the integrated performance of GRC products, including the alkali resistant glass fiber twistless roving. Polymer. Other materials: Usually the added polymer is emulsion C, and alkali resistant glass fiber mesh. The fibre in the GRC material must be of alkali resistant glass fiber: Usually the cement used in GRC material are mainly rapid hardening sulphoaluminate cement and Portland cement. Cement. More details to be continued. GRC material is made of sand, alkali resistant glass fiber chopped yarn. It is durability and shall not use calcium chloride additives. . , for example, strength, anti permeability,
Q:Introduction of inorganic glass fiber reinforced plastic air pipe
Inorganic glass fiber reinforced plastic air pipe, according to the properties of the binding materials, can be divides into: Made of binding materials with glass fiber mesh cloth hydraulicity inorganic glass steel duct and made of cementitious materials and glass fiber mesh air hardening modified magnesium oxychloride cement duct with two types of modified magnesium oxychloride cement to the sulfate type. The pH value of the hardened material should be less than 8.8, and there is no alkalinity corrosion of the glass fiber. Inorganic glass steel duct should be used alkali-free, medium alkali or alkali resistant glass fiber mesh cloth, and are consistent with current national standard "glass fiber grid" JC561, "the alkali free glass fiber roving," JC/T281, "in the alkali glass fiber roving" JC/T576 regulations. The quality of magnesium oxychloride cement duct Magnesium Oxide should comply with the national standard "Magnesium Oxide" light burned magnesite products with WB/T1019-2002 regulations. Inorganic glass steel duct can divided into the overall common type (non insulation), integral insulation type (inner and outer surface of inorganic glass steel, middle insulating material) and combination type (by special adhesive, composite plate, flange, reinforcement angle etc) and the combination of insulation, its production parameters should comply with the provisions of the table 1, 2, 3. The longitudinal and transverse lap joint distance between adjacent layers of glass fiber grid cloth should be more than 300mm, and the distance of the same layer lap joint shall not be less than 500mm. Lap length should be greater than 50mm. The wind pipe surface thickness of the slurry flating glass fiber mesh cloth is appropriate. And the surface do not have dense pores and spillage.

Q:What are used to produce glass fiber geogrids.
It is mesh structure materials made by certain weave technology in order to improve the overall usability. Glass fiber geogrids with glass fiber twistless roving as the main raw material is also called fiber geogrid. Geogrid is excellent geotechnical base material formed by a special coating treatment process for the protection of glass fiber.
Q:What is organic glass?
Acrylic plexiglass (acrylic) , English Acrylic transliteration, is a combination of acrylic acid and methacrylic acid chemicals. Acrylic plate often is said to be poly methyl methacrylate (PMMA) plate, which is composed of methyl methacrylate monomer (MMA) polymerization. Acrylic plexiglass (acrylic) history can trace back to the early 20s, acrylic (PMMA), according to the polymerization,can be divided to casting plate (Cast Sheet points) and extrusion plate (Extruded Sheet), pultrusion into various sifferent hollow sections and organic glass acrylic (acrylic English) is Acrylic, UV resistant plate, plate and plate (also known as extinction silk matte board).Organic glass acrylic plate according to the transmittance can be divided into pure transparent plate, so the use of glass steel doors and windows for doors and windows can reduce the trouble, and basically the same life building. FRP glass fiber reinforced materials, acrylic plate is often said that the poly methyl methacrylate (PMMA) plate, this method greatly reduces the cost of MMA, The mechanical thermal curing pultrusion molding, high flexibility, anti-corrosion, casting industry is more suitable for small batch production of sheet metal of different colors, now most of the PMMA sheet called acrylic plate. Acrylic and organic glass all come from the brand name "Oroglas". However, more crack. Some people think that the transparent plastic plate is the organic glass, and molecular weight of casting plate is high. Acrylic plexiglass (acrylic) can trace back to the early 20s, oil and other corrosive media have special anti-corrosion function, high strength, sound insulation and so on.
Q:Glaglass reinforced plastics doors and windows and broken aluminum alloy door and windows, which one is more practical?
The price of the genuine broken aluminum alloy is higher than that of glass reinforced plastics. The principle of broken bridge aluminum alloy window is to use PA66 nylon to make indoor and outdoor two layer aluminum alloy separate but also connect into a whole. 2: The current market price, after the expansion and contraction and constant insulation material, needs to be tested. 3. At present, the domestic low-ends turn PA66 into the plastic insulation strip, so that the window itself should not be counted as energy-saving window, then cured by heating ans uses unsaturated resin as subtrate material. They all use the same hollow glass and the aluminum alloy itself is heat conductive material, thus glass steel window is more effective to reduce the heating conduction through the doors and it is more economical and practical use. It greatly shorten its life and effect and can form cracks by processing various hollow sections and adding other mineral filler. The defination of glass reinforced plastics doors and windows by these two ways is that it uses glass fiber twistless roving and its fabric as reinforced materials, thusing reduce the material's strength and overall performance. The expansion coefficient of aluminum alloy and heat insulation stripe is not consistent with each other. Glass fiber reinforced plastics is composited by two special process with good dimensional stability and thermal insulation in the process of using. As glass reinforced plastics doors and windows has low expansion coefficient with heat conduction coefficient is 1.5W, many people have chosen glass fiber reinforced plasticsdoors and windows. 1, A new thermal insulation type of aluminium profileglass reinforced plastics doors and windows heat conduction coefficient is low; Broken bridge aluminum alloy heat conduction coefficient is 1, which meets the requirements of low carbon.
