Application
Glass Wool are widely used in public, commercial and residential buildings as well as industrial plants, for applications such as roofing, external wall, partition wall and floating floor to provide fire protection, thermal insulation, acoustic control and condensation control.
- Q: What's the difference between the rock wool and glass wool?
- Glass wool belongs to a category of glass fiber, and is a kind of man-made inorganic fiber. Taking quartz sand, limestone, dolomite and other FIR stone as main raw materials, and is melted into glass after mixed with some pure alkali, sodium borate and other chemical raw materials. In melting state, transfer them into flocculent fibers under the effect of external force, fiber and fiber are in three-dimensional crossing and winded with each other, presenting many little gaps. The gaps can be regarded as air voids. Therefore, glass wool can be regarded as porous materials, it has good heat insulation and sound absorption performance. Glass wool is a kind of spongiform material shaped by making melten glass fibering, it's chemical content belongs to glass and is a kind of inorganic fiber. It has good molding, small bulk density, low thermal conductivity, good thermal insulation and heat insulation, good sound absorption, corrosion resistance and stable chemical performance.
- Q: What are the advantages of Rock wool and import glass wool respectively?
- Rock wool has a high burning point, and a good hydrophobic performance after adding hydrophobic agents. The diameter of import glass wool fiber is about 5 microns. The degradosome of which has no harm, besides veneering is relatively strong which can be 1.8 meters. And it provides additional support to heat bridge system.
- Q: Which is more expensive between glass wool and rock wool?
- Relatively speaking, gass wool is more expensive.
- Q: What are the disadvantages of glass wool? What are the technical limitations in application?
- Each insulation material has its own advantages and disadvantages. Let's take glass wool and rock wool as an example. Glass wool is less irritating to the workers' skin than than rock wool is in construction workers, but we can not say that the glass wool is not irritating at all. Besides, the melting point of glass wool and rock wool is different. The thermal insulation effect of glass wool is better than rock wool when they have the same bulk density and thickness.
- Q: Are foam glass and glass wool the same?
- Different.
- Q: Which kind of soundproof cotton is the best for decorative gypsum board partition ? Mineral rock wool or glass wool?
- Materials must be completely sealed to the inside wall. The price is about 40-60 yuan per square meter. Dust will cause respiratory allergies, so pay attention to protect the construction workers. Construction methods are the same. Official places are prefer to 80KG per cubic meter. They are all made up of brittleness fibres, thus needing materials with high density to get a better effect of sound insulation. Rock wool and glass wool are similar in term of overall performances. Do not pulverize. Usually high-grade. Sound-absorbing effect is reflected in the wide-range noise reduction. The price is about 55-80 yuan per square meter. It can effectively inhibit sound transmission generated by resonance when being attached to the back of thin plate. High sound barrier mat is reflected in its high damping performance. If it is perforated ceiling, glass wool must not be used, for middle and low frequency. Without exhaust vent, it may cause pruritus in construction. The advantage of the product is more environmentally friendly. But the price is much higher. Now it is said that gradient sound absorption wool has the best sound insulation effect on current maket. It can be directly put on the keel gap space, to reduce high-frequency sound effectively. This material can cause skin allergies, so sealling board at the outside.
- Q: Who can tell me about the unit weight of glass wool board?
- It depends on what density you need. The formula is length * width * thickness * unit weight = the weight of the glass wool. For example, if it is 20 meters long, 1.2 meters wide, 50 mm thick, and the unit weight is 20kg / cubic, that is to say, 20 * 1.2 * 0.05 * 20=24kg. 48kg / m? means that the weight of one cubic meter is 48kg, you can imagine that with a piece of 50 square millimeter, how many of them can make a piece of cubic meter? You can get the answer by dividing 48, namely 48÷(1÷0.05)=48X0.05=2.4kg
- Q: What is the price of glass wool felt ?
- Hope you can provide the thickness and unit weight of the roll mat you need. Different unit weight, different price. Now the price is between 3300-3500 yuan and are increasing.
- Q: What's the heat conductivity coefficient of Kunnai glass wool blanket?
- Between 0.03-0.06, generally the lower the heat conductivity coefficient is, the better the thermal insulation effect is.
- Q: What is the construction technology of glass wool felt aluminium expanded sheet sound-absorbent wall?
- Dry laying a layer of asphalt felt →install wood keel → install gypsum board → paste glass wool felt → pave and nail a layer of glass fiber cloth → install aluminium expanded sheets → fix aluminium expanded sheets. 2, Operating points of the construction method. a, Embedded anticorrosion wood bricks: During masonry construction, laying bricks while pre-casting anticorrosion wood bricks (40 × 60 × 60), and the horizontal distance is 400 to 500 with the vertical distance of 400.
