Q:What are the exterior wall thermal insulation materials?

Organic thermal insulation material:Such as rice straw, rice husk, sugarcane fiber, softwood, kapok, sawdust, wood shavings, wood fiber and their products.Advantages: this kind of material has a small volume, a wide range of sources, most of the low price, but the moisture absorption is large, easy to decay after damp, and easy to decompose or burn at high temperature.

Q:What are common house thermal insulation materials?

Mineral wool. Rock wool and its productsMineral wool is the industrial waste slag as main raw materials by melting, cotton like insulation material made by injection method and centrifugal method: cotton is a natural rock as raw material is made of mineral wool. The commonly used rock such as Xuan Wuyan, diabase, amphibolite etc..Mineral wool characteristics: mineral cotton and products is a high-quality insulation materials, has more than 100 years of production and application history. The utility model has the advantages of light weight, heat preservation, heat insulation, sound absorption, good chemical stability, no burning and corrosion resistance, abundant raw material sources and low cost:Main use of mineral cotton: its products are mainly used in the walls of dry buildings, roof, ceiling and other insulation, insulation and sound absorption, but also made of waterproof felt and pipe sleeve.

Q:Is the calorimeter for building materials calorific value?

Calorific value calorimeter for building materials is used to determine the calorific value of building combustible materials such as stone, wood, concrete, and even dispersed mineral wool and polymers.In the standard set / group under the condition of oxygen nitrogen calorimeter specimen is placed in a certain quality of a constant volume, in order to test the temperature rise test as the foundation, considering all the heat loss and latent heat of vaporization, heat of combustion calculation sample.

Q:Protective clothing is glass cotton wool type

Rock wool is mainly a small number of fibers, more harmful to the human body, so it is recommended that operators wear protective clothing in operation.Pure textiles, natural fibers, cotton, hemp, wool, silk, chemical fiber, polyester, viscose, nylon, nylon, spandex, polypropylene fiber, Teflon, etc.. A blended fabric is a fabric woven from two or more of the above materials. Blended fabric is more suitable for the fabric of work clothes. According to the different personal style structure and loose. Before and after the open. Open cover and bare. Early and open. Then the body and in vitro.

Q:What kinds of exterior wall thermal insulation materials are there in Northwest China?

Experts from authoritative institutions of Beijing Haina LIAN inorganic fiber spraying technology Co., Ltd. development of ultra-fine inorganic fiber spray identified, it is for the further development of the enterprise is undoubtedly a new impetus. I learned that the evaluation results, both for the enterprise is also happy, for the enterprise how to further enhance their ability of research and development and to further explore this, more hope that the enterprises can take the assessment results in the East, as the struggle to make "Heiner fertility LIAN" on the floor again!

Q:What are the exterior wall insulation materials?

Benzene plate. The price of this material is relatively cheap, because its heat preservation effect is not ideal. And after the rain will be deformed, very easy to absorb water; therefore, the use of this material usually waterproof.

Q:What materials should be used for building energy saving? Why?

Energy saving materials are widely used in building energy saving materials development and promotion in China. They have significant social, economic and environmental benefits, with great potential. At present, China's common energy-saving insulation materials are mainly rock wool, glass wool, polystyrene foam, cement, polystyrene board, silicate composite insulation mortar.

Q:Advantages of exterior wall energy saving and environmental protection heat insulation coating

At present, there are many kinds of exterior wall insulation materials in the market, which can be divided into organic insulation materials and inorganic insulation materials. Materials are inorganic active insulation materials, foam, mineral wool products, foam glass, expanded perlite insulation, powder particles insulation slurry EPS, spraying mineral cotton, foam cement insulation products, vacuum insulation panel etc..

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 building energy saving materials?

Glass wool is second kinds of products of mineral wool, with silica sand, limestone, fluorite and other minerals as the main raw material, by melting method and centrifugal method, using flame or high energy gas blowing process, the molten glass liquid made of inorganic fiber. Glass wool products have good thermal insulation, heat insulation, sound absorption, non burning, corrosion resistance and other properties. They are widely used in building, piping, storage tanks, boilers, aircraft, ships and other parts of the insulation, heat insulation and sound absorption.
