With the continuous development of urban construction, the earth's natural environment has been continuously destroyed.  In order to promote the sustainable development of centrifugal glass wool, environment-friendly and low-carbon thermal insulation new building materials glass wool came into being.


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 high temperature melting.  But what are the differences?  Today, Uetersen xiaobian from raw materials, manufacturing technology, application fields to help you popular science.


I. 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, fire prevention, non-toxic, corrosion resistance, small volume weight, low thermal conductivity, strong chemical stability, low moisture absorption rate, hydrophobicity and other characteristics, is now recognized as one of the better performance of heat preservation, heat insulation, sound absorption materials.  

Superfine glass wool is quartz sand, feldspar, sodium silicate, boric acid and other as the main auxiliary materials.  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 glass fiber thermal insulation material produced by centrifugal method. The melted glass raw material is made of block material made by fibrosis spraying thermosetting resin by centrifugal spraying process, and then after deep processing by heat curing, it is made into a series of products with various uses.  

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

Three.application field  

Centrifugal glass wool has a very wide range of properties due to its sound absorption, insulation, thermal insulation, low moisture absorption rate and good hydrophobicity.  The boards, felt and tubes made of this material have not been used in the fields of building, chemical industry, electronics, electric power, metallurgy, energy and transportation for a long time for heat insulation, sound absorption and noise reduction, and the effect is more obvious.  

Superfine glass wool surface sticking aluminum foil or PVC film, is also widely used in thermal equipment, air conditioning constant temperature, hot and cold pipeline, oven, drying room, refrigeration and refrigeration and building insulation, heat insulation, sound insulation and other aspects. 

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