Q:How to distinguish the glass fiber yarn
Q:Technology classification of glass fiber reinforced plastic manufacturing process
Impregnation device, tension measurement and control system, will be added with curing agent (initiator), the production of a single product, small batch of products. The basic process is municipal engineering and other fields. (2) the method of the pre-impregnated material unit is used to cut machine fiber reinforced material properties, and pultrusion machine can be divided into horizontal and vertical machine. Under a certain pressure and temperature, mould pressing material is gradually curing, and the reinforced material is usually alkali free or medium alkali glass fiber and its fabric. 2. Molding equipment filament winding machine is main equipment of filament winding technology with beautiful appearance. Auxiliary equipment includes presoak yarn heater and curing equipment and so on. Under the environment of a certain temperature, it can get continuous electric power and plastic by curing. The matrix resin usually uses unsaturated polyester resin or epoxy resin with wood planing machine. It is widely used in chemical industry. It mainly places the resin on the mould coated with release agent by hand so that the two bonding together. The principle of pultrusion forming process is formed through the continuous hauling by hauling device, in which its product can replace metal. 3, Furnace for heat treatment. It is actually the four stages of the development of winding machine. Filament winding machine is the main equipment of fiber winding process. Overlong kneading time will result in obvious thermal effect. There are no special requirements for the structure of workshop. According to the position of the furnace for heat treatment and the drying baker, the dipping groove, it mainly includes impregnation vessel, grinding wheel chip type, molding mould and curing equipment.
Q:What is glass fiber extrusion
Glass fiber extruding machine set can be used to produce different shapes of glass fiber reinforced plastics in different shapes, which can be formed by the oven traction machine oil pump station and so on.
Q:Detail information about polyester powder binder for glass fiber felt
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 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.
Q:How to deal with the folding force of glass fiber plastic coated yarn.
The glass fiber itself has no fracture resistance, which can be improved by coating impregnating compound with tensile strength of the yarn can also be improved. In summer, the weather features with high temperature and humidity, which should be controlled at 28 degrees of temperature and 75 of the humidity so that the damage to yarn is relatively small. You may consider to improve the toughness of the coating material.
Q:What type of cement is used in the common GRC component?
Of course, the low alkali rapid hardening sulphoaluminate cement is good, but we do not use it as the cost increased, and the additive is double glass fiber mesh cloth. Cememt ans sand shall be simple packed. If it is the large mount, we could use machine for production
Q:What are the advantages of the glass reinforced plastics antenna? What is the difference between an ordinary antenna and a glass reinforced plastics antenna?
waterproof. structure of the antenna is different from the conventional vertical antenna, but the principle is the same. They all are sealed.
Q:What are the types of glass fiber yarns?
According to different diameter, glass fiber yarn can be divided into yarn and roving general. The yarn is usually used for producing curtains.
