Common types of insulation materials and USES!
Inorganic fiber insulation material
2.1 mineral wool. Rock wool and its products
Mineral wool is a kind of cotton-like insulation material made of industrial waste slag after melting and by means of blowing or centrifugation: rock wool is a kind of mineral wool made of natural rocks, commonly used rocks such as basalt, diabase and amphibolite.
Characteristics of mineral cotton: mineral cotton and its products are a kind of high quality insulation material, with a history of more than 100 years of production and application.It is light, heat preservation, heat insulation and sound absorption. It has good chemical stability, non-combustion and corrosion resistance.
Main USES of mineral cotton: its products are mainly used to dry the walls, roofs, ceilings and other parts of the insulation insulation and sound absorption, but also made of waterproof felt and pipe sleeve.
2.2 glass wool and its products
Glass wool is a kind of fibrous material made of glass material or broken glass after melting. It includes short cotton and super fine cotton.
Characteristics of glass wool: at high and low temperature can maintain good insulation performance;Good resilience;It has good sound absorption performance for all kinds of sound waves and noise.Good chemical stability, no aging phenomenon long-term performance unchanged, product thickness, density and shape can be processed according to user requirements.
Main application: the short cotton is mainly made into glass wool felt and rolled felt, which is used for building insulation and sound insulation, ventilation and air conditioning equipment insulation, sound insulation and so on.Superfine cotton
To be made of glass wool board and glass wool tube cover. Dry large recording studio, cold storage, warehouse, ship, aviation, tunnel and housing engineering insulation, insulation, also can be used for heating, water supply, power and other equipment pipeline insulation.
2.3 aluminum silicate cotton and its products
Aluminum silicate cotton is 3 ~ 5 (including m diameter of aluminum silicate fiber, also called refractory fiber, is a high quality the chamotte. High purity alumina, silica, zircon sand as raw materials, etc. Choose the appropriate processing, injection or melt spun by resistance furnace, and make the same and different chemical composition and structure of dispersing materials aggregated fibrosis of inorganic material, is recognized as the current domestic and foreign new heat preservation thermal insulation material with high quality.
Features: light weight, high temperature resistance, low heat capacity, low thermal conductivity, excellent thermal stability, excellent tensile strength and excellent chemical stability.
Main applications: widely used in electric power, petroleum, metallurgy, building materials, machinery, chemical industry, ceramics and other industrial departments of industrial kilns high temperature insulation closed and used for filtering, sound absorption materials.
