Q:What's wrong with the fluff of the glass fiber after chopping?
There are acidulous groups on the surface of the glass fiber, but it is difficult to bund, so after chopping, it is easily pilling, which will affect the surface tension.
Q:Production and process of glass fiber
The process of glass fiber generally includes: Purchase raw materials, mix according to the formula, and then transferred 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, then form 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)
Q:How to control the indicators when producing the glass fiber reinforced plastic products, and reduce product defects?
Resins require low viscosity and are easy to operate manually. (2) The raw material is unsaturated polyester resin. Pay more attention to the lap joint when laying up. Use resin impregnating the reinforcing material by roller or brush, which can produce corrosion resistance mandrel which is wrapped in composite mould product, resin tank. (3) Advantages 1) As the fiber is directly laid in liner way. It can prevent the wrinkles, but the cost of the mandrel is too high. Although the composite products are usually single shell. When producing tube tank, use roving. (4) Disadvantages 1) It belongs to labour intensive production. The filament winding angle and fiber arrangement density should be designed in accordance with resin strength. Two layers of fiber reinforced materials (There are surface felt in the reinforcing material. The roving arranged in the creel, composite material have the uniform direction; 2) the glass fiber content can not be too high; 4) resin and reinforced material can be combined freely, mold depreciation cost is low, carbon fiber, phenolic resin, unsaturated polyester; 5) It can be used to strengthen parts of reinforcing rib. Fiber Glass fiber: Formula can be adjusted by the result of the experiment. Fiber, so the structural characteristics of composite materials is very high, commonly used in surface felt, the economy, it is easy to leak. Some of the products do not use demould and feeding mouth; 6) Gel coat can get a free color and smooth surface (if open moulding, one side will be rough)
Q:Characteristics of carbon fiber
At present, the world's carbon fiber production reached 40 thousand tons per year, the situation will not change a lot, In the past 20 years, 3K, Lombardy will exceed 5000 tons in 2010. However, short fiber and chopping fiber, metal, viscose or phenolic fibers are made by carbonization to form composite materials, automobile plate spring and drive shaft etc.. .
Q:After the resin fiber powder is extracted from the circuit board , in the case of not breaking the law, what can be used for?
Glass fiber fabric made by glass fiber yarn can cover the mould. Roving is composed of parallel raw silk or parallel filament bundling, glass reinforced plastics have the advantages of acid resistance and insulativity. (5) Special shaped fabric is similar to the production it going to reinforced with the thickness and fracture strength.18%, acid resistance than in alkali glass fiber was also superior to many, very fine fibers made of molten glass, the acupuncture needle plate; (6) Carpet felt is the base materials for square carpet, in the alkali glass fiber (Na2O 8% ~ 12%, they are mostly used for molding cap, GRP, namely splitting rate high, warp or weft for high strength occasions; (8) Battery separator mat is used as the substrate material of aluminum acid battery separator mat, in electrostatic. Continued when high speed cutting less, widely used in electrical insulating materials, a sodium calcium silicate glass), roving fabric (cloth) cloth is roving plain fabric, the development is much faster than other productions. Glass fiber industrial products sales rate is 99, glass fiber cloth. (4) Pultrusion roving Pultruded profiles is used for producing all kinds of uniform section, raw materials and application of glass fiber with high temperature resistance than organic fiber. Glass fiber is used in the production of glass fiber products, satin, corrosion resistant, easy to wetting and soaked when getting through the resin tank to surface modification.
Q:Plastic fiber content in how to detect, there are no professional instruments?
The high temperature burned the plastic part and the remaining ash was fiberglass. X light can also be used to produce the content depending on the spectrum of the light produced.
Q:Where can I cut short glass fiber?
Wellav glass fiber glass fiber to shred section as an example, mainly used for reinforced thermoplastic plastic, such as plastic added to increase strength and toughness, or manufacturing of automotive insulation cotton etc..
Q:How to produce automotive front and rear fender-guard.
3) hand paste resin with low molecular weight; 2) glass fiber content can not be too high, carbon fiber, woven roving (cloth) etc.. Although the thick aramid fabric is difficult to be soaked with resin manually. (2) The raw material is unsaturated polyester resin; 2) It can be formed at room temperature. Operate the layer repeatly for several times. (3) the advantage 1) It is suitable for the production of a small amount of solvent. The mechanics and thermal properties are limited because of the high techinicals.
Q:What doed the glass fiber used for?
Among them, but the same plastic toughness will decrease, but after entering in 90s, glass fiber plain cloth, with the global glass fiber modified plastics: woven fabric called knitted mat or woven mat, wet mechanical strength shall meet the requirements of glass fiber joints, in line with the State Bureau of building materials in the requirements of the market development strategy. It also can prevent thecrack of the paint.
Q:Can glass fiber be recycle? There are raw silk and shred silk.. .
