Q:An introduction to glass fiber window?screening
It is made of glass fiber and PVC. The weave and process uses glass fiber monofilament plastic coated process and is formed by weaving, heating and shaping.
Q:Is glass fiber reinforced plastics a special steel
Glass?reinforced?plastics (FRP) is also known as GRP, namely glass?reinforced?plastics, which generally refers to use the glass reinforced fibre as the matrix of unsaturated polyester, epoxy resin and phenolic resin. Reinforced plastics using glass fiber and its products as reinforced material is called glass fibre reinforced plastics glass?reinforced?plastics. Due to the different types of resin used in it, there are also called polyester glass?fiber reinforced?plastics, epoxy glass fiber reinforced plastic, phenolic glass fiber reinforced plastic. It is light but hard, non-electrical conduction, high mechanical strength, less recycling and corrosion resistance. It can use to manufacture machinery parts, automobile and ship shell instead of steel.
Q:Does glass wool belongs to glass fiber cloth?
No, glass wool belongs to the one category of glass fiber and it is a kind of artificial inorganic fiber. Glass fiber cloth is twistless roving plain fabric made by glass fiber cloth.
Q:What is the function of adding fiber material to concrete ?
In projects, some fiber materials such as paper, hemp fiber and straw are added to concrete. If plastering mortar is added into mixer, it can play the role of skeleton, improve the crack resistance and tensile strength of the plaster layer and enhance the flexibility of floated coat and durability in order to reduce floated coat contraction and make it not easy to fall. The characteristics of the fiber material will be introduced as follows: firstly, paper reinforcement includes dry and wet paper. Dry paper is use at the time of adding quick lime, It was tore up, was removed dust and soaked with water, and then 100 kg lime and 2.75 kg paper are mixed. When using, it should be made into powder by a small steel mill and 3 mm aperture sieve filter. When wet paper reinforcement (commonly known as pulp) was used, each 100 kg lime should be added into 2.9 kg wet paper reinforcement. Specific operation method is the same as that of dry paper. Secondly, the use of hemp fiber requires tenacity and purities. To make is loose, it need to be dried, linen and then it is cut into 20 mm to 30 mm. Each 100kg lime adds 1kg loose hemp which is hemp fiber grey. Thirdly, grass stalks are usually cut into rice straw or wheat straw which is no more than 30 mm long. It could be used after half a month after soaked in lime water. It also can be used as paper after soaked in lime or caustic soda. Fourthly, synthetic fiber mainly includes polypropylene fiber and nylon fiber used for mortar. When using, you should pay attention to its disparity and alkali resistance. These are the all material fiber used in concrete. You should be familiar with the characteristics of the material in order to make better use of it.
Q:What are the differences between glass fiber and asbestos?
Various kinds of products are formed finally which is called yarn number (t). The content of chrysotile is the most abundant. The diameter of glass fiber monofilament is from a few microns to twenty micron. 2 or more primary yarns are formed into added twist yarns by folded twist which is widely used. Glass fiber twist or twistless roving are formed into spun yarn with different specifications and usage. There mainly are alkali free. Composite line is formed by two or more fold twist. Glass fiber is a kind of inorganic nonmetal material with excellent performance. It uses glass ball or waste glass as raw materials and is formed by high temperature melting. It mainly is used for producing glass?fiber products. It has no degree of twist and it is spray forming reinforced material and insulation,electric insulation and heat or thermal insulation material which is also called double twist yarn. It mainly is used for hand lay-up glass?reinforced?plastics and is known as detwisting yarn in glass fiber industry. The meaning of metric system number. This yarn is called primary twist yarn which is bundling filaments combined by impregnating compound, namely 24tex. It is mainly used for testing the thickness of the original silk, laminate and winding. The metric system number is recommmended by the international organization for standardization(line destiny). 3 metric system number: The fineness degree of the yarn is expressed by the yarn quality of the unit length, which is equivalent to a hair. The smaller the number is, the thicker the yarn is. Monofilament is equal to 20tex. There are many kinds of asbestos whcih is widely used and usually is called monofilament. The former is a fixed length, the latter is a fixed weight.
Q:The difference among organic glass, glass steel and acrylic.
It is composed of methyl methacrylate monomer (MMA) polymerization, having the same life of the building. After a special process, the two kinds of composite organic glass acrylic (acrylic) can be compound, with the English name Acrylic. The extrusion can better control the thickness of the plate.
Q:Epoxy resin mortar mix ratio
200 to 300 of mortar and 100 of epoxy resin will be fine. It should be added according to concentration. Construction convenient and high quality can be reported as the premise.
Q:What materials are used to the special grid plate of the carwash?
We call it geogrids with the frame made by the glass fiber twistless roving. The matrix is mainly unsaturated polyester resin
Q:What is the difference glass fiber roving and fine yarn ? Does the equipment used for production have any difference.
6 microns non-alkali, 9 micron twistless roving (bulk yarn), 80 alkali , 30 twist roving ans 21 medium alkali. It is a glass fiber integrated production enterprises combined management, scientific research and development. The company has advanced production equipment and strong technical force. Main production includes 30 alkali-free glass fiber yarn and 40 fine yarn with annual production of 1500 tons.
