What is the difference between superfine glass wool and centrifugal glass wool with the continuous acceleration of urban construction, the earth's natural environment has been continuously destroyed.  In order to achieve sustainable rapid development, glass wool, a new building material of environmental protection, energy saving and heat preservation, emerged at the historic moment.

Glass wool is mainly divided into two kinds of centrifugal glass wool and ultrafine glass wool.  Centrifugal glass wool is a kind of glass fiber material produced by centrifugal method. Superfine glass wool is a kind of fiber cotton obtained by melting at high temperature.  But what's the difference?  Today xiaobian from raw materials, manufacturing technology, application field three aspects to give you a popular science.  

  

One, Raw materials  

  

Centrifugal glass wool is composed of natural minerals such as quartz sand, dolomite, sand and other inorganic materials.  These glass materials do not contain formaldehyde and other harmful substances, safety and environmental protection, no irritation, at the same time with flame retardant, non-toxic, corrosion resistance, small volume weight, low thermal conductivity, strong chemical stability, low moisture absorption rate, hydrophobicity and many other advantages, is currently recognized as the most superior performance of heat preservation, heat insulation, sound absorption materials.  

 

Superfine glass wool is made of quartz sand, feldspar, sodium silicate, boric acid and so on.  It has the characteristics of light bulk density, small thermal conductivity, large absorption coefficient and good flame retardant performance.  

  

Two, manufacturing process  

  

Centrifugal glass wool is a kind of glass fiber insulation material made by centrifugal method. The glass raw material in the molten state is made of filamentous material made of fiberized thermosetting resin by centrifugal spraying process, and then it is processed by heat curing and made into a series of products with a variety of uses.  

 

Superfine glass wool insulation material is the raw material after high temperature melting, made into less than 2um fiber cotton, and then add thermosetting resin adhesive pressure high temperature finalize the production of various shapes, specifications of the board, felt, pipe products.  

   

Three, application field  

 

Centrifugal glass wool has a wide range of uses because of its sound absorption, sound insulation, heat insulation, low moisture absorption rate, good hydrophobicity.  The boards, felt and tubes made of this material have been widely used in the fields of building, chemical industry, electronics, electric power, metallurgy, energy and transportation for heat preservation and heat insulation, sound absorption and noise reduction, and the effect is very remarkable.

After pasting aluminum foil or PVC film on the surface of superfine glass wool, it is also widely used in thermal equipment, air conditioning constant temperature, hot and cold pipes, ovens, ovens, refrigerated preservation and building heat preservation, heat insulation, sound insulation and other aspects.   

 

Because the centrifugal glass cotton is soft and the fiber is fine, it will not stimulate the skin during construction, so it is welcomed by construction units and becomes the preferred product of heat preservation and insulation.
