Q:Comparison of plexiglass steel bridge and inorganic glass steel bridge

7, low cost, small fluctuations in raw material prices. 8, heat insulation, sound-absorbing. 9, non combustible. 10, the waste can be used for processing, after smashing the landfill, no pollution to water, soil and air, is an ideal material of environmental protection. Disadvantages of inorganic glass fiber reinforced plastics: 1. Toughness is lower than plexiglass. 2, waterproof performance second only to plexiglass.

Q:Why a broken glass film

A ton of glass raw materials, at least 3-4 of nickel sulfide crystals, the number of tons of glass made of pieces of a square size glass, which will have 3-4 to explode, which is self depicting the image of.

Q:There are several ways of heating the industrial drying tunnel furnace and are different from each other?

The stainless steel heating tube heats the fluid by forced convection. The material is made of stainless steel is in a head with a heater pump to pump fluid into the heating chamber, after heating in the heater, another head out, is a kind of forced circulation pump through a heating method, compared with the traditional heating methods, energy saving, scientific process, installation has obvious economic benefits easy to use.

Q:What's the price of 0.85mm thick plexiglass, please?

Domestic cheapest, about 400 or so, but the thickness is not enough, the material is poor

Q:Does fiberglass contain formaldehyde? I'm a hair salon. Buy a glass fiber reinforced plastic shampoo bed, there is always a pungent smell of the body, there is no harm to it, including formaldehyde free

Because of the different kinds of resins used, they are called polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic resin glass fiber reinforced plastics. The main raw materials of glass fiber reinforced plastics are resin, curing agent and glass fiber. Glass fiber is not toxic, but contact the skin will be itching. And resin and curing agent have certain harm to human body, especially curing agent, if it is the curing agent of aromatic amine, that is relatively harmful to human body.

Q:What's the difference between heat resistant glass and tempered / reinforced glass?

Acid and alkali corrosion resistance by 3.3 (linear thermal expansion coefficient for (3.3 + 0.1) * 10-6/K) super high heat-resistant borosilicate glass material, the basic ingredients of sodium oxide (Na2O), boron oxide (B2O2) and silica (SIO2) belongs to the non-toxic side effects in borosilicate glass PYREX glass so excellent corrosion resistance.

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

Glass fiber is a kind of inorganic nonmetallic material with excellent properties. English name is: glass, fiber or fiberglass. Composition of silica, alumina, calcium oxide, boron oxide, sodium oxide, Magnesium Oxide etc.. It is prepared by high temperature melting, wire drawing, winding and weaving process with glass balls or waste glass as. All kinds of products formed finally, glass fiber monofilament diameter from a few microns to twenty micron, the equivalent of a hair 1/20-1/5, each bundle of fibers are hundreds or even thousands of root root filaments, usually as a reinforcing material of complex materials, electrical insulating materials and insulation materials, circuit board, etc. and widely used in various fields of the national economy.

Q:Who has information about power plants chimneys, water glass, acid resistant concrete?

Water glass acid resistant concrete raw material: water glass, acid resistant concrete raw materials, including cementation material, curing agent, acid resistant aggregate and admixture. The composition of water glass and acid resistant soil is different, and the prepared concrete will have different properties and range of application. 1) cement material - water glass: building engineering usually use sodium silicate glass (including Na20). Divided into powder water glass and liquid water glass according to their different states. Liquid water glass is a fine quartz sand, S102 (or quartzite) mixed with sodium carbonate in a certain proportion, placed in a furnace of 1350 - 1400 DEG C, and cooled by melting reaction to be a semi-finished product of solid water glass. The solid water glass is put into the autoclave, and the water vapor is dissolved into water so that a practical liquid water glass can be obtained. The liquid water glass can be obtained by two times of spray drying, which is usually called sodium silicate powder. The modulus and specific density of water glass have great influence on the properties of concrete. In order to guarantee the technical performance of acid proof concrete, the water glass of suitable modulus and specific density must be chosen. According to the experience of acid proof construction, water glass modulus 2 is recommended. From 6 to 3.O, the corresponding specific density is from 1.38 to 1.40. Water glass appearance is colorless, slightly blue transparent or translucent viscous liquid.

Q:The main raw material for the impact of float glass cost?

Fuel prices: heavy oil, natural gas or coal, etc., because of the large number of long-term consumption, so it is also an important factor affecting product costs.

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

Raw material:Glass fiber reinforced plastics (FRP), also known as GFRP, that is, fiber reinforced plastics, generally refers to the use of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics made from glass fiber or its products are referred to as glass fiber reinforced plastics or glass fiber reinforced plastics.
