Q:Which is better, asbestos free calcium silicate and aluminium silicate refractory fiber?

Aluminum silicate fiber can be divided into many kinds according to the aluminum content, the use temperature range is relatively large, the heat insulation property is good, but the price is more expensive.

Q:What is the maximum temperature at which the glass is cured?

Glass is softened at a temperature of 600 degrees. When making glass, but ordinary alcohol lamp is enough to soften it. Glass is not crystal. The softening point of lead glass is 500 degrees. The main component of ordinary glass is CaO: Na2O: 6SiO2, which can be softened by fire. In addition to the ordinary glass, glass wire, alcohol burner 1000 degree glass has no definite melting point and freezing point, in softening products can be made into any shape, so there is no fixed melting point, clarification, fluoride special glass based raw materials, slightly higher than 1200 DEG C melting, but the softening point, as well as borate, limestone, mixed melt in glass kiln.

Q:Eterpan and yinte in what is the difference?

Calcium silicate board:Calcium silicate board is mainly inorganic mineral fiber or cellulose fiber and other loose short fiber materials with siliceous and calcareous materials as the main cementing material, pulping, molding, in high temperature and high pressure saturated steam curing acceleration, sheet formation of calcium silicate gel made.Calcium silicate board is a new type of building and industrial plate with excellent properties. Its products are fireproof, moisture-proof, soundproof, moth resistant and durable. It is an ideal decorative board for ceiling and partition. Excellent waterproof performance, just can prevent the home improvement for a long time damp deformation, especially in the bathroom for a long time in a humid environment, the use of calcium silicate board ceiling is the best choice.

Q:What are the three major effects of fly ash in concrete?

The "form effect" of fly ash contains many glass beads, the surface is smooth and the texture is dense. It is this form to water reducing effect, compact and homogeneous effect, can promote the early hydration of cement flocculation effect of solution, change the mixture rheological properties, the initial structure and hardening of the various functions, especially for pumping concrete, can play a good role in lubrication.

Q:What is dew point of thermal insulation material?

The heat insulation lining has the characteristics of low thermal conductivity, small density, high flexibility, fire prevention, waterproof, etc..Light weight, 10 96kg/m3, 20kg/m3 following mat, 24 48kg/m3 as in hard, 48 96kg/m3 as core, which 48kg/m can fand a softening point of the ceiling, 500 degrees C, 300 degrees C insulation, the larger the amount, k=0.9.Calcium silicate insulation product was successfully developed in 70s. It has the characteristics of high compressive strength, small thermal conductivity, convenient construction and repeated use. It has been widely used in power systems.Most of the domestic universal small workshop production, have been imported from the United States after the four production lines, advanced technology, instant rejection speed fiber, dry needle felt, stable quality, high temperature 800 to 1250 DEG C.Features: acidity derivative of more than 2, high temperature resistant, general chemical pipe 1000 degrees C more, must use this material. The temperature is about 2000 C.

Q:Calcium silicate board white ICI belongs to wood surface paint?

ICI can generally be considered as wall paint (latex paint), and latex paint can be used on this kind of cement board. And lumber is different, it is not suitable to brush latex paint on the surface of wood, it can only be decorated with paint (oil paint).

Q:What is the main role of fly ash added in concrete products?

The workability of fresh concrete can be improved by adding fly ashThe workability of fresh concrete is affected by the volume, water cement ratio, gradation, shape and porosity of the aggregate. The fly ash is used for fresh concrete is the obvious benefits of increasing the slurry volume, slurry filled with aggregate between pores, inclusions and lubrication of aggregate particles, so that the concrete mixture has better cohesiveness and plasticity. The aggregate particles of fly ash can reduce the interfacial friction between the paste and aggregate, and improve the workability of the concrete mixture at the contact point of the aggregate.

Q:What are the high temperature resistant insulation materials at 400?

According to the general rules of equipment and piping insulation, heat insulation material is a material with a thermal conductivity of less than 0.14W/ (m*K) when the average temperature is equal to or less than 623K (350 degrees Celsius). Heat insulation material is usually light, porous, porous, small thermal conductivity characteristics. Generally used to prevent heat loss of equipment and pipes, or frozen (also known as general cold) and low temperature (also known as cryogenic) use, so in our country, insulation materials, also known as insulation or cold preservation materials. At the same time, because of the porous and fibrous structure of thermal insulation material, it has good sound absorption function, so it is also widely used in the construction industry.

Q:What are the production methods of calcium silicate board material?

The synthesis process of dynamic method is carried out under stirring, the synthesis temperature is higher than the static process, and under the compression condition. The dynamic method is simple, no gel chemical order, products made of small capacity, good performance, can obtain high temperature (1000 degrees Celsius) of xonotlite products and ultra light products, but the need for high pressure vessel with stirring device, equipment and process condition requires high energy consumption and investment are higher. At present, this method is adopted abroad.

Q:Eterpan with calcium silicate is sold on the market are the same thing? Non asbestos calcium silicate board is Eterpan it

The market is generally understood, but in fact, Eterpan belongs to Guangzhou eternit limited production of the 100 year history of eternit brand board, because the cement product is Belgium hetet group invention.
