Q: External wall insulation rock wool board construction points and matters needing attention, know how much?: Rock wool, also called asbestos, is a kind of mineral cotton. It is made of natural rock and mineral and is made of fluffy, short and fine fiber.

Q: How can the exhaust pipe of a gas water heater be insulated by going through the glass?: Gas water heater exhaust pipe are now dual structure: the inner tube is the exhaust pipe, the fan will strong combustion exhaust water heater forcibly discharges the indoor air inlet pipe; the outer tube is, the outer air (oxygen) gas suction water heater for combustion.

Q: What are the differences between slag wool and rock wool?: People usually referred to as mineral wool rock wool and slag wool, so easy as the two are the same thing, even thought that the slag wool color white, gray green wool is more than "pure", this is a misunderstanding. Although they are all mineral cotton, there are still some differences that can not be ignored. The main reason for these differences is the composition of the ingredients.

Q: Protective clothing is glass cotton wool type: Rock wool protective clothing can choose special anti small dust protective clothing, such as DuPont tyvek1422a protective clothing, this kind of protective clothing is relatively good cost performance, but also inexpensive, can prevent 0.01 microns diameter foreign body.

Q: What are the building thermal insulation materials in general?: Commonly used building thermal insulation materials are benzene board, Extrusion board, polyurethane spraying, etc..

Q: How about the appearance of glass wool, mineral wool and asbestos?: Glass wool belongs to a kind of glass fiber, it is a kind of man-made inorganic fiber. Quartz, sand, limestone, dolomite and other natural ore as the main raw materials, with a number of soda ash, borax and other chemical raw materials into glass. In the melting state, by means of external force, the system is thrown into flocculent fibers, and the fibers and fibers are made of solid intersection. They are intertwined with each other and show a lot of small gaps. This gap can be considered as a pore. Therefore, the glass wool can be regarded as a porous material and has good thermal insulation and sound absorption performance.

Q: What kinds of fire retardant coatings are there in steel structures?: Because this type of ultra-thin fireproof paint coating, making use of thick and thin fire retardant coating for steel structure is greatly reduced, thereby reducing the total cost of the project, the steel structure has been effective fire protection, fire effect is very good.

Q: What is the difference between ordinary slag wool rock wool board and basalt rock wool board?: Although rock wool and cotton products belong to CaO-Al2O3-SiO2 Portland slag system, but because of differences in their chemical composition on (Table 2), making them the phase composition of crystallization point falls in different regions in the CaO-Al2O3-SiO2 three phase diagram (Figure 1). From table 2 and figure 1 shows that the rock composition point (4, 5, 6 in the figure) are located on the 2 wollastonite gehetinite 2 calcium feldspar crystallization zone (CS-C2AS-CAS2 zone), the solid phase will have the three crystalline phase because of wollastonite, gehetinite, calcium do not have hard water feldspar characteristics, the water change is very small, the rock wool has good water resistance.

Q: What are the exterior wall insulation materials?: Polyurethane, this material is the best performance of other materials in the insulation cotton, the use of more, such as refrigerators, cold, and so on. The thermal conductivity is much lower than that of the benzene and extrusion panels, and the price is much higher.

Q: Is the calorimeter for building materials calorific value?: Hebi Huanuo coal testing equipment ZDHW-8000A high precision microcomputer automatic calorimeter for measurement of electric power industry, coal, metallurgy, petrochemical, environmental protection, quality inspection, cement, paper, geological exploration, scientific research institute and other departments to measure the coal, coke, petroleum, cement, brick and heat it solid or liquid fuel. In accordance with the national standard GB/T213-2008 "method" the requirements of the determination of calorific value of coal. The high precision microcomputer full automatic calorimeter is the main instrument in the coal quality laboratory.
