Q:How long is the fire endurance of fire resistant rolling shutter door?
According to the new national standards GB_12955-2008 for fire doors from January 1, 2009, fire doors are classified acoording to thermal insulation fireproof door(A),part heat insulation fireproof door(B) and non thermal insulation fireproof door(C), rather than thermal insulation fireproof door. At the same time, the original fire endurances of class A, B and C fire doors are adjusted to 1.5h, 1.0h and 0.5h respectively. So, GB is 1.5h
Q:What are the characteristics of thealuminium oxide refractory?
Physical properties of refractories include structural properties, thermal properties, mechanical properties, performance and job performance. The structural properties of refractories include porosity, bulk density, water absorption, air permeability and pore size distribution. The thermal properties of refractories include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity and thermal emission rate, ect. Mechanical properties of refractories include compressive strength, tensile strength, flexural strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength and modulus of elasticity, ect.
Q:What is the fire endurance of ceramsite concrete blocks?
The fire endurance of 240mm thick ceramsite concrete blocks is 2.9 hours. It is made by adding pottery into fine aggregate, using cement as binding material, by mechanical mixing, molding machinery and natural protection. Ceramsite building blocks are used as wall material, which can reduce workers' labour intensity. It saves work and material. There is no empty drum during rendering. It is not easy to produce fissure. It has sound insulation, good thermal insulation performance, and is convenient to decorate. Nails, expaned setscrew and no wood anvil can be directly hit into wall. Moreover, It has high firmness.
Q:What is the best refractory company?
Palladium activity is very rich ah, Sina micro-blog introduced a lot of jewelry related content, style is very unique, see people could not help but want to store to buy impulse.
Q:Refractory factory grinding brick dust harmful to the body?
Therefore, in the workshop work must pay attention to do their own protection.
Q:The manufacturing technique of refractory material
The major components of alkaline refractory material include magnesium oxide and calcium oxide. The commonly used alkaline refractory material is magnesia bricks. The magnesia bricks with 80%~85% magnesium oxide has good resistance to basic slag and slag and higher refractoriness than clay bricks and silica bricks. It is mainly used in open hearth, oxygen blowing of converter, electric furnace and smelting non-ferrous metal equipment and other high temperature equipment. Refractory materials applied on special occasions include high temperature oxide refractory materials such as alumina, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, etc., refractory compounds such as carbide, nitride, boride, silicide and sulfide, etc., and high temperature composite materials, including metal ceramics, high temperature inorganic coating and fiber reinforced ceramics, etc. Consult and find reference for efractory materials production equipment, go to http://hi.baidu.
Q:Which schools are the best schools in the world for learning knowledge about refractories?
Wish it helps you out.
Q:Which are fire proofing thermal insulation materials?
Fire proofing thermal insulation materials include: fire proofing heat insulating brick, fire proofing thermal baffle, fire proofing thermal insulation paper, fire proofing thermal insulation felt, fire proofing blocking, fire proofing fiber bulker, castable refractory, etc. Yizhen Decoration wish you a happy life!
Q:Which are roofing fireproofing material?
(1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation. Besides, it is also characterized by excellent sound proofing, penetration resistance, easy construction, safety and environmental protection without toxin and pollution. (2) Foam glass is featured by light weight, small heat conductivity coefficient and water absorbption, non-inflammability, fire resistance, high strength, no moulding, corrosion resistance, non-toxin and stable physical and chemical properties and thus widely used petroleum, chemical engineering and underground construction. It is also featured by thermal insualtion, heat/cold preservation and sound absorbption and thus can be used for thermal insulation of external wall and roof of civil builduing. Foam glass is featured by stable chemical property, easy to be processed and not easy to deforme, and durable. (3) With slag, basalt and other natural ore as the main raw material, rock wool, mineral wool and its products are made by high temperature melting into fiber, and then processing with binder. It has low thermal conductivity, fire resistance, easy construction and good effects of energy saving and thus is highly cost-effective. (4) With phenolic foam material as main material, phenolic resin plate is made by foaming thermoset phenolic resin. It is featured by light weight, fire resistance, no burning in the air, no smoking, non-toxin, no dropping and non-embrittlement and thus is an ideal thermal insulation material used in HAVC projects. Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.
Q:How much is refractory spraying coatings?
Different brands and models have different prices. For example: Refractory temperature: 1580 ~ 1770 ℃ | Brand: Hengli | Product category: dedicated castable for biomass burning machine | Material: castable Price: 3000.00 refractory temperature: 1770 ~ 2000 ℃ | Brand: Great Wall | Category: unshaped refractory material | Material: corundum mullite Price: Refractory temperature: 1580 ~ 1770 ℃ | Brand: Guanghuayaoye | Product category: refractory material| Material: high alumina Price: 2500.00 The above prices obtained from the Internet are for reference only, and please pay attention to the purchasing price.
