Q:whether the fire resistant level of aerated concrete building blocks can reach the grade one?
the fire resistant level of aerated concrete building blocks can reach the grade one level. Aerated concrete strength grade shall be divided according to the concrete cubic compressive strength value. Use the symbol C and the cube compressive strength value (in N / mm2 or MPa gauge) to express. According to GB50010-2002 "concrete structure design specifications" provisions, ordinary concrete is divided into fourteen levels, namely: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80 .
Q:How is the development of Xinmi refractories industry? What's its advantages and disadvantages?
I don't know how it has developed. Its advantage is the coal industry. You have to know the generating capacity in Xinmi thermal power plant first, and then you will know their coal cinder yield, after all, this is the raw material. Xinmi is not far away from Zhengzhou. The real estate in Zhengzhou is still good. I'm not sure about the others.
Q:Refractory factory grinding brick dust harmful to the body?
The effect is very large and belongs to lung disease.
Q:What's the A grade fireproofing material?
1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire retardant coating; 9. fire-proof sealing material.
Q:What are the main components of refractory cement?
SiO powder is often used. Ultra-fine powder refers to less than 1 / zm particles which are made by hydrolysis of ethyl silicate or made from recycled dust in the smelting process of ferro-silicon alloy. Non-cement castable refractory are castable refractory material which contains no cement instead it relies on the coagulation and combination by adding ultra-fine powder or sol (see refractory castable), and it is an amorphous material with high activity. Silica sol is made through Ion-exchange of sodium silicate after Na ions are removed. The easiest method is to prepare by reaction of aluminum metal with hydrochloric acid or alchlor. It is a thermodynamically unstable system which has certain requirements for ultra-fine powder and sol. It is different from non-cement refractory castable, Cr2zrOz and etc. It has low impurity content, and can bond with itself, so it has good binding strength. Ultrafine powder used in non-cement castables are SiO2, Al2O3, Cr2zrOz, etc. Such recycled SiO2 powder has an average particle diameter of 0.5 pm, therefore when adding the gelling agent (electrolyte), it can coagulate and give the products some bonding strength. Non-cement castable refractory is made up of refractory aggregate and powder and it is round. Since the use of superfine powder or sol as binder. The size of sol particles are of 0.1 ~ 1 m. Non-cement refractory castable takes oxide or synthetic compound ultra-fine powder or oxide sol-gel which is similar to the chemical composition of material in tungsten castable. There are several ways to prepare alumina sol. The sol used are mainly alumina oxide and silica sol. The surface area is large, and it helps to improve high-temperature structural strength. Non-cement castable refractories rely on oxide ultra-fine powder or sol to coagulate and combinate. It is a refractory castable (also known as chemical bonding castable) which uses chemical binder instead of cement for combination.
Q:What is fire retardant coating mainly used for?
Fire retardant coating is a coating which is applied to the surface of buildings and structures and can form a protective layer of fire retardancy and thermal insulation. It can reduce the flammability of the coated materials and block the rapid spread of fire so as to improve fire endurance of the coated materials. Features of fire retardant coating: (1) Fire retardant coating itself has a flame-retardancy or non-inflammability, and it can prevent the protected substrate from direct contact with the air, and delay ignition and reduce the burning speed of the objects. (2) In addition to flame retardancy or non-inflammability, the fire retardant coating itself has a a low thermal conductivity, which can delay the transfer of flame temperature to the substrate to be protected. (3) When heating, fire retardant coating decomposes non-combustible inert gas to dilute the combustible gas decomposed by the protected, making it difficult to burn or slow down the burning rate. (4) Fire retardant coating containing nitrogen will decomposite NO, NH3 and other basic groups, which compound with the organic radicals and interrupt the chain reaction so as to reduce the temperature. (5) intumescent fire retardant coating will expand and foam when heating, and form a carbon foam insulation to block the protected objects, thus delaying the transmission of heat to the substrate.
Q:What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?
You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
Q:Which kind of refractory does insulation board belong to ?
Q:What is the principal part of silicious refractory material
Shenzhen Longgang Jiangyou Hua Boiler Accessories Co., Ltd. is specialized in refractory cement, refractory mortar, refractory clay, refractory aggregate and perlite. And other refractory | thermal insulation material, it has cooperated projects in Shenzhen, Huizhou, Dongguan, Guangzhou, Foshan, Zhuhai and other sites. For more information you can find our website on Baidu.
Q:What are the new types of refractories? What are the characteristics? Their applications and developments?
A new type of refractory materials are: A12O3-TiO2-SiO2 refractories, MgO-A12O3-TiO2 refractories, MgO-CaO-TiO2 refractories, MgO-SiC-C refractories, nanotechnology MgO-C brick, MgO-AL2O3-AIN refractories, MgO-La2O3 refractories etc..
