Q:What kind of raw materials should be used in making FRP?

Synthetic resin is a kind of synthetic molecules by a large amount of polymer, usually called polymer, also known as synthetic resin in polymer. The performance after heating is different, can be divided into thermosetting resin and thermoplastic resin two categories.Thermosetting resin refers to the heat or curing agent (including initiator) under the action of crosslinks and become insoluble and infusible solid state of a kind of resin, such as epoxy resin, phenolic resin, unsaturated polyester resin, furan resin. This resin can not soften cured after heating. High temperature decomposition and destruction.

Q:What are the raw materials for making glass?

Sandstone fused glass has a bright luster, and has a good transparency, acid resistance and mechanical strength.

Q:Can the toughened glass be cracked by the sun?

thermal stabilityTempered glass has good thermal stability, can withstand the temperature difference is 3 times of ordinary glass, can withstand the temperature difference of 300 degrees celsius.

Q:What's the difference between three kinds of glass fiber board, epoxy board and FR4 board?

FR4 is the pure epoxy board of NEMA standard. The normal color should be dark green. This is the color of epoxy. There are also yellow, generally called yellow FR4 called yellow material, white (green) called white material.FR4 is more expensive than epoxy board and fiberglass board cannot confirm the price.

Q:As the raw material for glass wool is what

Collectively, the fibrous silicate glass wool can be split into thin and flexible fiber and available.Glass wool has been used for thousands of years of history.

Q:What are the raw materials for low dielectric glass fiber?

Glass fiber is divided into different grades according to its composition, properties and uses. According to the provisions of the standard level (see table), E glass fiber is most widely used, widely used in electrical insulating materials; special fiber grade S, while the output is small, but very important, because it has super strength, mainly used for military defense, such as bullet proof box; C level more than E with chemical resistance in the battery isolation plate, chemical filter; a basic glass fiber reinforced materials used in the production.The main component of glass fibre and its main components are silica, alumina, calcium oxide, boron oxide, sodium oxide, Magnesium Oxide, depending on the amount of alkali content in glass, can be divided into non alkali glass fiber (Na2O 0% ~ 2%, which belongs to the aluminum borosilicate glass), glass fiber (8% ~ sodium sodium calcium silicate glass 12%, a boron containing or not containing boron) and high alkali glass fiber (Na2O 13%, sodium calcium silicate glass).

Q:What material is the automobile glass made of?

Among them, laminated glass refers to a transparent adhesive plastic film affixed to the two or three layers of glass, the plastic strength and toughness of glass and hard to combine together, increasing the glass's crushing resistance. Toughened glass refers to ordinary glass quenching. Internal stress was formed to some extent, so that the strength of the glass has been strengthened, the impact is broken, the glass will split into small pieces with a blunt edge, not easy to damage the occupant.

Q:The difference between crystal glass and glass

Gloss: turn a high grade crystal glass against the light, and you will find it like a beautiful handicraft. White, glittering and translucent, and reflects the charming multicolored light, and low-end crystal or ordinary glassware in these areas there will be a big gap. What's more, in some ordinary glass containers, there are a lot of bubbles, and the color will be dirty and dark.Purchase of crystal glass

Q:Glass factory raw materials specific to do?

The glass is the main component in the manufacturing process of quartz sand, quartz sand is combined with other chemical materials at high temperature (1300 degrees Celsius) crystallized after firing the cooling of the body, with a hard, abrasion resistance, corrosion resistance and high transmittance characteristics, its wide application has a long history. The manufacturing technology of the use of glass a thousand li a day, increasing by the clock, glass, doors and windows, lamps, such as high-tech electronic components and space technology, are indispensable glass. Our daily contact with most of the "flat glass is" thick to thin for doors and windows, clocks and the use of medical tests, the manufacturing method is that the furnace in the glass slurry level or traction method (also called float) and vertical traction method. After the dissolution of soluble traction after furnace also has the cooling system, cooling after the completion into a "flat glass, flat glass thickness mainly depends on the speed of traction, traction faster, can be manufactured and thinner. Although the ordinary flat glass from the front appears bright transparent, but from the side near the edge is slightly blue, because the amount of glass color depends on the main raw material in the manufacture of glass - quartz sand and iron content of purity. Generally, the thin glass used in the watch industry is superior in quality but expensive in value. The main difference is that the raw material used in the quartz sand is superior and the iron content is very low (usually under 3/10000)

Q:Raw material, processing method and ratio of glass fiber reinforced plastic

Processing method:Basically divided into two major categories, namely wet contact and dry pressing molding. According to the characteristics of the process, there are hand molding, laminating, RTM, extrusion, molding, winding and so on. Hand molding also includes hand paste method, bag pressure method, spray method, wet paste low pressure method and no mold hand paste method.
