Q:Who knows well about which is better in thermal insulation between aluminum silicate ceramic fiber cotton and asbestos?
Certainly the asbestos has better thermal insulation effect. External wall insulation rock wool board is specially designed and manufactured for the buildings’ external wall insulation thin plastering system, and it applies to external wall insulation, energy conservation and renovation of the newly-built or existent buildings with compact structure of the concrete or brick wall as the basic foundation. External wall insulation rock wool board is dedicated to external wall insulation. As superior incombustible, fireproof and thermal insulation material, it has the advantages of higher compression resistance and tensile strength, lower hygroscopicity, good dimension stability with no thermal expansion or shrinkage, and ageing resistance. It can adapt to the external wall system, and provide many properties of effective thermal insulation and energy conservation, fire protection and extreme climate protection for buildings. Rock wool is incombustible, and won’t give out heat or toxic fumes. It can cut off the flame spread in an effective way when fire occurs. It has superior fire resistance. With superior thermal insulation and heat-shielding performance, it is capable of increasing the thermal resistance of the building envelope, reducing buildings heating and air-conditioning energy consumption, and saving energy and reducing emission. It doesn’t produce corrosion to metallic materials like carbon steel, aluminum (alloy), copper, or all kinds of building components either. It has physical properties of efficient sound absorption, noise reduction and elastic damping. With low hygroscopicity and ageing resistance, it can keep long-term stability. It is also lightweight, and easy to cut, saw and install.
Q:How is the quality of ceramic fiber vermiculite cloth?
The quality is good. The refractory temperature of ceramic fiber vermiculite cloth is 1200-1450 degree. Ceramic fiber is a kind of fibrous lightweight refractory material with light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat and mechanical shock resistance and other advantages, so it is widely applied in industries such as machinery, metallurgy, chemical engineering, petroleum, ceramics, glass and electronics.
Q:What are the features of ceramic fiber module?
It has good chemical stability; excellent thermal stability and good elasticity. When ceramic fiber module is in a state of prepressing and after the furnace lining is completed, the expansion of the ceramic fiber module makes lining seamless and can compensate the shrinkage of fiber lining so as to improve the heat-insulating performance of fiber lining. The overall performance is good; It possesses excellent thermal stability and thermal shock resistance; Ceramic fiber module is quickly installed. The anchoring parts are set on the cold face of wall lining to reduce the requirements of anchoring parts materials.
Q:What are the specifications of ceramic fiber blanket?
Ceramic fiber blanket Double needling thread throwing blanket of ceramic fiber Product description: white color, regular size, set fire resistance, heat insulation, thermal insulation in one. Do not contain any binder. Maintain good tensile strength, toughness and fiber structure during the long-term use in neutral and oxidizing atmosphere. Temperature resistance is 950-1400℃. Ceramic fiber injection fiber blanket Product description: good chemical stability; good thermal stability; good tensile strength; low thermal conductivity; low thermal capacity; good sound-absorbing and noise reduction performance.

Q:What is the standard of ceramic fiber board?
It shall be light, resistant to high temperature, good in heat stability, low in thermal conductivity and specific heat, and resistant to mechanical shock. And it shall be exclusively used in the environment of high temperature, high pressure and easy abrasion.
Q:What’s soluble ceramic fiber?
1. As a fibrous light refractory, the ceramic fiber is combined with excellent performance of traditional thermal insulation material and refractory material. Involved in many areas and widely used in various industry departments, its product can be seen as base material used to improve the thermal performance of thermal equipment like the industrial furnace and heating device, and realize structure lightening and energy saving; 2. It boasts low thermal conductivity, good thermal stability and chemical stability without corrosivity. The brake lining made from the fiber possesses high temperature resistance and dispersity, and is suitable for all sorts of blender mixers to stir; 3. It’s applicable for brake linings with requirements on high temperature resistance, thermal recovery and little noise in the brake area.
