  • The difference between rock wool felt and rock wool board

    2019-08-26 13:59:22
    They are different in uses. 1. Rock wool board is mainly used in plane, such as roof or wall; 2. Rock wool felt is mainly used in arc or slope areas. 3. The length of the board is limited, and the length of the felt can be about 6M, which is more suitable for wrapping tubular or boiler. 4. Another difference is that the bulk density is different, the greater the bulk density, the greater the strength, the less easy to bend; the smaller the bulk density, the smaller the strength, the easier to roll;
  • Soundproof glass wool is very important of Neighborhood relations

    2019-08-26 10:40:27
    The people are coming from everywhere to live in the same building. There will inevitably be some conflicts between different personalities, living habits and local customs. In families with children, children are more lively and active. They may play ball, run and sing at home. This will affect the neighbors, especially downstairs.
  • The difference between rock wool and glass wool

    2019-07-15 16:28:09
    Everything has two sides. They are difference products but also have something in common. Glass wool is a kind of artificial inorganic fiber, which belongs to one category of glass fibers. It has good moulding, small volume density, low thermal conductivity, thermal insulation, sound absorption, corrosion resistance and chemical stability. Rock wool​ is the artificial inorganic fibers made of basalt melted at high temperature are characterized by light weight, low thermal conductivity, heat absorption and non-flammability.
  • What is Glass wool?

  • Glass wool has unique sound absorption performance

    2019-05-13 16:45:07
    Glass wool has better sound absorption function to high frequency sound.The main factors affecting the sound absorption function of centrifugal glass wool are thickness, density and air resistance.Density is the component per cubic meter of data.Air drag is the ratio of air pressure to air velocity per unit thickness.Air flow resistance is an important factor affecting the sound absorption function of centrifugal glass wool zui.The flow resistance is too small, the elucidation data is scarce, the air oscillation simply passes through, the sound absorption function drops;The flow resistance is too large, and the data is dense.Regarding the centrifugal glass wool, the sound absorption function has flow resistance.

  • What is glass wool felt, what effect does glass wool felt have?

    2019-04-14 22:27:30
    Centrifugal glass wool felt is a kind of filamentous material made of fiberized and sprayed thermosetting resin by centrifugal spray method for the glass with molten appearance, which can be made into series of products with multiple USES by further processing through thermal curing.
  • Introduction to noise reduction process of glass wool

    2019-04-08 10:58:50
    Glass wool is after high temperature and high speed and then through the curing process of products, in the case of high temperature and low temperature can reflect a good sound-absorbing effect.First used in the room ceiling, ceiling, engine body, engine room and studio such local, the first is to take a fancy to his noise reduction role.So, how does it accomplish noise reduction, this needs us to understand. Glass cotton in the entire history of the building materials market has not the position of the firm, that is because people now is pay attention to environmental protection, and the glass wool is very safe in the building materials, and has the very high corrosion resistant function and heat preservation, the two strengths in high-rise building temporary is indispensable, and glass cotton can be cut at random, it also brought a greater convenience to the architect, so it will be temporary in the previous position in building materials sales.
  • Can glass wool be used in exterior insulation systems like rock wool?

    2019-04-01 10:53:27
    With the continuous advancement of building energy conservation, the types of exterior insulation materials are increasing, and the sudden increase in the requirements of thermal insulation and fire protection regulations has led to serious confusion in the external insulation market. Some materials that do not meet or are not suitable for wall requirements have been used in exterior insulation. Among them are glass wool. Glass wool belongs to a category of glass fibers and is an artificial inorganic fiber. Glass wool is a material in which molten glass is fiberized to form a cotton-like material. The chemical composition is glass, and the surface is generally made of aluminum foil paper.
  • Types of Glass Wool In Steel Structure Sorkshop and Installation Precautions

    2019-03-19 10:32:43
    Steel-structured glass wool belongs to a category of glass fibers and is an artificial inorganic fiber. Natural minerals such as quartz sand, limestone and dolomite are selected as the primary raw materials, and some raw materials such as soda ash and borax are melted into glass. In the ablation state, by means of external force, the blown type is formed into flocculent fine fibers, and the fibers and the fibers are three-dimensionally intersected, and are surrounded by each other, exhibiting many fine voids. This void can be seen as a void. Therefore, glass wool can be regarded as a porous material with outstanding heat insulation and sound absorption.
