Q:Classification of alkali free glass fiber
Q:how to produce glass reinforced plastics grating
Production technology, there are mainly three konds of glass reinforced plastics grating production process: Peciprocating filament winding process, continuous filament winding process and casting process. Reciprocating filament winding process(belongs to fixed-length method): In this process, the leaching glue tank with rotating mandrel reciprocate and the long glass silk with a certain angle works as auxiliary. Auxiliary angel (the winding angle) is controlled by the moving speed of leaching glue tank and the speed ratio of mandrel and translational motion of leaching glue tank is controlled by computerized electric machine. The layer number of twisting is gradually increased to meet the thickeness of design wall. After winding is completed, resin in products should be solidified and then form mandrel from glass reinforced tube. Continuous filament winding process (belongs to continuous method) The process is that pipe pass through a feeding station which is to supply resin presoak roving, chopped glass reinforced fiber, resin sand mixture. then pipe formed in the continuous progress of mandrel. Casting process (belongs to fixed-length method) In this process, chopped glass fiber reinforced materials and sand are put into the steel mould fixed in bearing, then unsaturated resin used as catalyst is added into one side of steel mould to dip reinforced materia. Under the effect of centrifugal force, the resin exchange fiber and filler in the air so as to create a nonporous compact composite material and a smooth, bright and clean pipe surface layer with rich resin. steel tubes start to curing under high temperature. Pipe produced in this way is also called glass reinforced plastic sand pipe. In the world, the number of manufacturers using reciprocating filament winding process to produce tube is more than that of the rest two production technology. One of the reasons is is that the former has a wider range of usage and its applicability is better.
Q:How to make the lining of tank acid-proof and anticorrosion.
If it is metal can, cleaning, descaling and brushing anticorrosion lacquer will be fine.
Q:Glaglass reinforced plastics doors and windows and broken aluminum alloy door and windows, which one is more practical?
At present, the broken bridge aluminum is applicable.
Q:Definition of glass fiber reinforced plastic doors and windows
The unsaturated resin is used as the subtrate material. it have many advantages such as sound insulation and so on. Glass reinforced plastics is also called glass fiber reinforced material with lightweight property. Glass reinforced plastics doors and windows use glass fiber twistless roving and fabric as reinforcement material. It is a new type of composite material developed abroad in early twentieth Century and can add other mineral filler.
Q:What is glass fiber?
It is a kind of boron silicate glass with corrosion protection. It also can used as chemical filter. As a reinforcing material of glass fiber, it has the following characteristics. It is alleged that it also has the potential as glass fiber reinforced materials with 86000MPa elastic modulus. It is upgraded alkali free glass fiber for the requirements of environmental protection. It belongs to a sodium calcium silicate glass containing boron or no-boron and high alkali glass fiber (over 13% sodium oxidation, the absorption of impact energy is very good, but it is very important). After processing, glass fiber can be divided into non-alkali glass fiber ( 0% ~ 2% sodium oxidation). Quartz sand belongs to sodium calcium silicate glass with good heat resistance. (1) with high tensile strength, it can be fused into a small glass beads under high temperature and also can used for the production of reinforced materials. (3) the elastic limit is large and the tensile strength is high. (7) good machinability, it is mainly used for enhancing the properity of cement. It also can be used for enhancing asphalt roofing. Its main component are silica and it is a typical sodium silicate glass so as to reduce environmental pollution. It also be widely used for the production of glass fiber. (11) It is not easy to burn with high strength. Its disadvantage is that it is easy to be eroded by inorganic acid. Its strength is greatly increased with high flexibility. Glass fiber is mainly used for electrical insulating materials, manufacture of reinforced plastic or reinforced rubber, electrical insulating materials and heat or thermal insulation materials and so on.
Q:Production process of glass fiber reinforced plastic
Technology of fiber reinforced epoxy resin composite, compared to traditional materials has a series of alternative properties since two technology are developing fastly. The composite are mainly maded up of reinforcing materials and subtrate materials. Reinforced material: Composite are mainly made up with CFRP and carbon fiber reinforcing materials. There are three kinds of materials made by composite, like GRP, exposy resin and subtrate materials. In this paper, epoxy resin composites use epoxy resin matrix, with the low curing shrinkage rate only 1%-3% and high saturated polyester resin, as high as 7%-8% and good adhesion; B phase is benefit to the production process; low curing volatile low curing stress; the performance of chemical resistance, good electrical insulation performance value ring oxygen resin solvent, alkali resistant machine performance compared with full power and phenolic acid polyester fat good; curing as a brittle, poor toughness 2 epoxy glass steel (ASTM) FW (fiber) epoxy resin and its products with steel manufacturing glass fiber enhanced
Q:Glass fiber thermal insulation belt for glass fiber.
It is mainly used for thermal insulation and is apply to wind high-temperature pipe fitting, cables and so on. It is formed by thick glass fiber yarn after bulk processing and usually uses glass fiber roving. It is widely used for electric heating wire and heating element.
Q:Which tensile strength of alkali resistant glass fiber mesh is bigger, the lateral one or longitudinal one?
The weaving method is staggered. Secondly, weft yarn is roving with its strength is less than the warp yarn.
Q:Does centrifugal glass wool is made from glass fiber
No, it doesn't. The glass wool is produced by the centrifugal glass and it is irregular and discontinuous and fiber diameter is indefinite. The glass fiber is produced by platinum bushing and wire drawing machine with roving diameter is more than 9 micron, spun yarn is less than 9 micron and ultra fiber diameter is about 4 micron.
