Q:What resin fiber powder can be used for?
扔掉
Q:Materials of european component
Polymer:.5%, the low alkalinity sulphoaluminate cement, forming perfectly, do not use additives which contain calcium chloride based. 2. It is anti-permeability. As the Portland cement, it can be formed at one time. 4, China requires that when using the ordinary portland cement, the zirconia's content do not less than 16, including alkali resistant glass fiber roving, white portland cement..5%:. 3. plasticizer: The fibers used in GRC must be alkali resistant glass fiber, fiber, early strength agent, alkali resistant glass fiber mesh and retarder. As the requirement of Europe and America, the content of zirconium oxide in glass fiber should be no less than 16: The acrylic emulsion is usually the polymer: We can add some of the volcanic ash active material selectively, that is, acrylic copolymerized emulsion. 5: We can select soft rubber mold, made by high temperature resin which suit the hard outer mold: High efficiency water and anti freezing agents reducing agent can be selectively added. That is conducive to comprehensive performance, enhance the durability of GRC products commonly. The cement can be hardening at fast speed. Sulphoaluminate cement /additives, alkali resistant glass fiber chopped yarn is easy demoulding.
Q:The manufacturing technique and process of glass fiber
Glass fiber is glass fiber semi-finished products which uses waste glass of different color after a series of processing complete sets of equipment of the glass fiber with its properties and application is very extensive. Its fineness is 0.03mm to 0.06mm and it is as thin as fine silk and as soft as cotton. It features with high tensil force resistance, white, non-poisoned, non-peculiar smell, high acid and alkali resistance, corrosion resistance, high temperature resistance, good insulation properties and it is widely used in building materials, oil and chemical insulation materials, especially the main material for the development of glass reinforced plastics. (1) selection and cleaning of raw materials. 1, all kinds of waste glass are used as raw material with diameter is no less than 3cm, but a lot of organics, mercury and high temperature glass are exception. 2, the cleaning of raw materials: We should put the selected material into cement pool and then add water into it and clean it by broom. After cleaning all the sidement on the surface of glass, you should put it into the other pool for cleaning it again. Finally, you should put it into iron sieve with loophole for seperating from water, then you can use the glass. 3, If there are greasy dirt on the surface of glass, you must press it down firmly, you must keep the crucible holder flat and melt the glass until it turns red so as not to cause electric shock. You should make the wire wrap around the drum, or it is easy to make the pot break.
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 sheaf packing in waste plastic industry?
1, It is sheaf packing, but not the debris or particles packed space bags. 2, White cast is the color of fracture part and it includes blue, white and slant blue. The white cast should be transparent or white.
Q:An introduction to glass fiber cloth
For the occasion requiring high warp or weft strength, the strength of woven roving mainly focus on the warp or weft direction of fabric. Roving roving is composed of parallel raw silk or parallel filaments. According to glass composition, twistless roving can be divided into unidirectional cloth E-GLASS alkali-free glass twistless roving and C-GLASS medium alkali glass twistless roving. Glass fiber woven roving is twistless roving plain fabric and is an important base material for pasting glass reinforced plastics. Moreover, it is also unidirectional weft cloth.
Q:How to control the indicators and reduce product defects when producing glass fiber reinforced plastic products.
Resins require low viscosity and are easy to operate manually. (2) pay attention to the overlap of the layer of raw materials, resin and unsaturated polyester. Enhance the materials by resin impregnation with roller or brusher, and then the corrosion resistance mandrel is made in the production made by the composite material. (3) advantages 1) As the advantages of straight fiber with reasonable line laying, as the inner lining, it could prevent wrinkles, so mould cost is high. Although the composite products are usually single shell. Twistless roving is used to priduce tube tank. (4) Disadvantages (1) It belongs to the labour intensive production. The filament winding angle and fiber arrangement density are designed according to the secondary active liquid thermosetting(subject to gel condensation) and two layers of fiber reinforced materials (reinforcing material surface mat.) The roving arranged in the creel, composite material and uniform direction; 2) the glass content can not be too high; 4) resin and reinforced material can be combined freely, mold depreciation is low, carbon fiber, phenolic resin, unsaturated polyester; 5) can be used to strengthen reinforced local enhancement.
Q:What is the technological process of glass Fiber chopped strand mat?
Fiber reinforced epoxy resin composite material forming process. Compared with traditional materials, the composite material has a series of irreplaceable characteristics, which has been developed rapidly since the second world war. Although the production is small, but the level of composite materials is one of signs that marks national or regional science, technology and economic level. Composite material is mainly composed of two parts: reinforced material and base material. Reinforced material: In composite material, some reinforced material such as the glass fiber in glass reinforced plastics and carbon fiber in CFRP(carbon fiber reinforced material) give major mechanical property to composite material. Matrix: Matrix is a single material which aims to make composite material as a whole such as resin in glass reinforced plastics( epoxy resin referred in this paper). Composite materialcan be divided into three kinds according to the matrix material: resin composite material, metal matrix composite material, and inorganic nonmetallic composite material such as ceramic matrix composite material.
Q:What is the difference between glass fiber reinforced plastic antenna and cannon antenna?
One is made of glass, the other is made of iron.
Q:Production process of glass fiber tube
The tube is made in continuous movement of mandrel. It should be feed into steel mould fixed in bearing. After continuous filament winding and centrifugal casting process finishes,the number of pipe manufacturers using reciprocating fiber winding process is more than that of other two production technology. After the resin in products has been solidified, you should inject unsaturated resin with catalyst at the one side of steel mould. This process is that pipe passes through a feeding station whcih aims to supply resin presoak twistless roving. There are mainly three manufacturing techniques of glass fiber pipe. Reciprocating fiber winding technology (belonging to the fixed length method). The main material includes glass fiber reinforced materials and sand. Auxiliary angle (wingding angel) is controlled by the ratio of impregnating vessel movement speed and mandrel rotate speed. Pipe usually solidifies under high temperature. With the help of centrifugal force, its applicability is very good. Continuous filament winding process(belongs to continuous method). Impregnating vessel movement is controlled by computerization machine. With the number of the layers increases gradually, inner tube form a smooth plane due to the centrifugal force and mandrel gets out of glass reinforced plastics pipe. Centrifugal casting process (belonging to the fixed length method). Tube made in this way, is also known as glass fiber reinforced plastic sand pipe. Reciprocating filament winding process In this process
