Q:Is it dangerous to make mineral cotton mattresses?

You should see the mineral wool mattress, mineral wool is Lord palm mattress, adding mineral wool because of mineral materials with various physical properties under certain conditions, such as far infrared energy and electric energy, magnetic energy, new products, general quality products.

Q:What are the common thermal insulation materials?

In architecture, it is customary to control the flow of heat through the houseMaterials called thermal insulation prevent the heat from entering the room from being called heat insulation material. Insulation, thermal insulation materials insulation materials called duncan. The commonly used insulation materials can be divided into two categories: organic and inorganic. In its shapeCan be divided into fibrous, porous, microporous, bubble, granular, layered and many other, here are some of the more common materials are briefly introduced.

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. [standard] group will oxynitride calorimeter specimen is placed in the specific 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:What is the heat preservation material?

According to the different material density, composition, range, shape and construction method of the insulation material, the classification is carried out:According to different bulk density is divided into: heavy 400~600kg/m3, light 150~350kg/m3 and ultra light, less than 150kg/m3 three categories.According to different ingredients: divided into organic and inorganic two categories.

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:Now, what are the new exterior wall thermal insulation materials?

At present do not know the new promotion is that kind, can only suggest you several, because of the advantages and disadvantages, in general, the insulation is not set fire, fire insulation, fire and insulation products prices high ridiculous.

Q:Rock wool, EIA inorganic insulation mortar, polystyrene particles, polystyrene foam board advantages and disadvantages comparison?

Rock wool (mineral wool): it is a kind of inorganic green product from natural mineral, non-toxic and harmless. The utility model has the advantages of good fireproof performance and good durability, and can be synchronized with the structure life, and the price is low. When the insulation performance is satisfied, the utility model can also have a sound insulation effect, and the fire prevention grade is level a. But the quality of rock wool is very different, and the heat preservation performance is good, the density is low, the tensile strength is low, and the durability is poor, and the paint can not be used directly.

Q:How can the interior drain be silenced?

Sound insulation material: high quality noise proof cotton. Home improvement does not recommend the use of rock wool or other mineral wool because of a little pollution. Although the ordinary sponge does not pollute, but the sound insulation effect is ordinary.Fixed material: tie band, convenient construction, good effect, strong rope can also. Tapes are not recommended for long periods and are easily removed from the sound proof cotton.

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: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..
