Product information
Perlite insulation material
I. Characteristics
High temperature resistance: the use temperature range is 1000℃~1790℃, can still maintain stable performance in high temperature environment.
Good heat insulation performance: It has the characteristics of low heat conductivity and low heat capacity, which can effectively prevent heat transfer and play a good heat insulation effect.
Good chemical stability: good acid and alkali corrosion resistance, not easy to react with other chemical substances, and can be used stably in complex chemical environments.
Excellent thermal stability: good thermal stability and thermal shock resistance, small thermal expansion, not easy to deformation or damage when the temperature changes.
Good mechanical properties: good resistance to mechanical vibration, elasticity, a certain tensile strength and toughness, not easy to be damaged under mechanical vibration or external force.
Good electrical insulation: it is a good electrical insulator and can be used for occasions where insulation is required.
Good sound absorption: It can absorb more than 80% of medium and high waves above 500Hz, and has good sound absorption effect.
Ii. Application
Metallurgy: Used to prepare high temperature lining, heat treatment furnace insulation materials, etc., improve the furnace temperature uniformity, reduce energy consumption.
Chemical: can be used as catalyst carrier, high temperature filtration material, etc., used in chemical reactors and high temperature gas dust removal.
Electricity: Often used in the manufacture of high-temperature furnace insulation material, can also be used in power station steam pipe and boiler coating material, improve energy efficiency.
Machinery: In the machinery industry furnace and other high temperature equipment used for high temperature furnace filling, kiln insulation layer and heat network pipe insulation and other projects.
Construction field: can be used to prepare fire boards, thermal insulation materials, etc., improve the safety performance of buildings, can also be added to concrete, prepare lightweight, high-strength foam concrete, reduce the weight of the building while improving thermal insulation performance.
Transportation field: can be used to prepare high-speed trains, cars and other vehicles of insulation materials, reduce noise, improve comfort, can also be used to prepare cars, high-speed rail and other vehicles of lightweight composite materials, reduce vehicle weight, improve fuel efficiency, enhance vehicle safety performance.
Environmental protection: Its filtration performance makes it an important material for environmental protection projects such as flue gas desulfurization and dust removal, and its corrosion resistance makes aluminum silicate fiber filtration materials still maintain a stable filtration effect in harsh industrial environments.
It can also be used for soilless cultivation and soil improvement.
