Q:The difference between glass fiber plain cloth and glass fiber woven roving.
According to the weight and width, there are many models including 200 g, 400 g, 600 g and 800 g. The width of 900, 1000, 1270 and 1400 are commonly used. The width is from a few centimeters to 3 meters and the weight is from 60 to 800.
Q:what are the material used for GRC decorative lines
Cement, sand, glass fiber. We should pay attention to anti-cracking in interior decoration.
Q:What can glass fiber grid do in road engineering?
The things generally are flexible materials, which is flexible than the asphalt concrete pavement.
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: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:What does glass fiber operating tools do ?
wire drawing,drying, winding, fabric and so on.
Q:A chromic acid concentration and what kind of glass?reinforced?plastics should be used in chromic acid waste gas purification and recovery device.
In general, glass?reinforced?plastics can be used for producing chromic acid waste gas purification recoverer device. Glass reinforced materials, namely glass fiber reinforced materials, has many advantages such as light weight, high strength, anticorrosion, thermal insulation, insulation, noise insulation and so on. Glass?reinforced?plastics doors and windows use glass fiber twistless roving and its fabric as reinforcing material and unsaturated resin as matrix material, and composite these two material by a special process add other mineral filler. After adding other mineral filler, various hollow sections are processed into the products by heating and curing. Generally speaking, the main characteristics of glass?reinforced?plastics doors and windows are: aging resistance and high strength. Glass fiber reinforced plastic without steel plate as the lining does not need any monomer auxiliary enhancement material, depending completely on its own to support the whole structure. Due to the glass fiber and its fabric as reinforcing material, without filament resin bonding bare, by mechanical thermal curing pultrusion molding, so it features with fracture resistance, anti-bending and deformation resistance. It also is corrosion resistance and has a long life. Glass fiber reinforced plasticbelongs to high quality composite material.
Q:Where is atmospheric toxic liquid containers and how to operate it ?
Color should be in accordance with the provisions in table 3 and it is not easy to fall off. Firstly, the surface of tube should be painted with soapy water or totally soaked in water. Rubber products should features with corrosion resistance and oil resistance. It should process liquid injection port sealing test.The technology file includes the following. Tank manhole and liquid injection port and strength layer can use resin with corrosion resistant as base material. When tank is out of factory, its surface hardness value should over 34. The defination of automotive paint coating. This standard uses the following definitions. It is in accordance with the JT with the minimum wall thickness is 5mm. Its head should adopt elliptic type head. The application of nitrogen should be adopted and it should be located at the right side of tank. The resin content should be controlled within 30% ~ 35% with the intake valve should be closed. A horizontal wavy plate should be installed. The test should be processed on a dedicated vent valve. Tank mark. A ring paint belt presenting transport liquid should be sprayed around the center line of the tank. Name of manufacturer. According to the method used in test 5, the outer surface should be smooth and oxygen content should between18% and 23% (volume ratio). Elliptical tank cross-section axial ratio is not greater than 2.12. The tank has vehicle safety requirements. The tank has not been thoroughly cleaned with its width is not less than 350mm. It is enduring dilute acid base rubber hose.
Q:Can you describe the production process of glass fiber and the production process?
The production process of glass fiber generally includes: Purchase the raw materials, mixed according to the formula, and then transfer to the glass furnace for melting and refining, after operation channel flow to the bushing, the sizing agent after coating by wire drawing machine traction, forming the original cake, and then flow to the rear section reprocessing procedures (usually a short cut, winding, weaving, puffing and twisting) or sell (direct yarn)
