Construction Service & Regulations

1.Check the size, specification, layout, installation and quality of the metal anchorage and make expansion

   processing of the anchors.

2.Erect the formworks (hardwood or steel) in advance.

3.Unpacking and pouring the castable

4.Mixing

5.Installation of the mixed castables & Large area constrction

6.Vibrating

7.Before the castable block get final set,it can not bear any pressure or vibration.

8.Curing & Stripping

9.Baking the Furnaces (taking cement plant kiln as an example):

1). Keep the initial temperature at 20°C or so.

2). Please strictly follow the curve to conduct the baking work and increase the temperature smoothly and

     evenly.

Specialised Refractory Castables for burner tube

3). Lay out as many temperature measuring points as possible to monitor the temperature in the kiln, ensuring

      the stable increase of the temperature.

Q:What kind of material is refractory bauxite?
Bauxite, also known as bauxite alumina or bauxite with high alumina, is the main raw material for the production of high alumina (aluminum content ≥48%, belongs to LAS) refractory. It must be calcined bauxite ore.
Q:Who knows how many fire heat preservation material are there?
There are many kinds of fire proof materials. The major material used in construction industry is fire proof and thermal insulation material, mainly include vitrified micro bead insulation board, class A expanded bead fiber board, rock wool board, plastic extruded sheet, polyurethane insulation board
Q:What type of firebrick does TZ-3 represent?
Height is 65mm, length is 230mm, and width is 114mm, that is the t-3 firebricks which meet the national standard.
Q:Who knows the model of fireproofing materials?
Inorganic binder: it mainly includes sodium silicate, gypsum, phosphate, cement,etc; refractory mineral filler: aluminium oxide, asbestos powder, calcium carbonate, perlite, cornstarch,etc; nonflammable organic resin: it mainly includes polyvinyl chloride, perchloro-ethylene, chlorinated rubber, neoprene latex, epoxy resin, phenol resin,etc. Nonflammable fireproof addictive: it mainly includes phosphorus, halogens, nitrogen organic compounds (chlorinated paraffins, TBP ( tributyl phosphate ), decabromodiphenyl ether), and borate series (boric acid, zinc borate, aluminium borate), antimony series, aluminium series, zirconium series and other inorganic compounds.
Q:What are the refractory materials above 1000℃
I have no idea what field you are in, and I am skillful at making refractory materials, because this is my job. You can send me an email informing your purpose, here is my email address sihouzm@yeah.net.
Q:How to make the service life of refractory materials longer?
Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
Q:What are the new types of refractories? What are the characteristics? Their applications and developments?
AZS refractories are often used brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials.Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on.Unshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..
Q:How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !
From the perspective of appearances, grade A is 70mm, B 50mm. Their materials are the same .
Q:How is the fire endurance of the fireproof paint?
fire endurance of fireproof paint is from 1 to 4 hours. Mechanism: Fireproof paint itself is flame-retardant or non-combustible, protecting the substrate from direct contact with the air,delaying the time for catching fire and reducing the burning speed. fireproof paint decomposes with heat and releases non-combustible inert gas, thining out the flammable gas produced by the protected object, making it difficult to burn or slow down the burning. expansive fireproof paint expands under heat and forms a layer of carbon foam insulation to cover the protected object, delay the heat transfer in the substrate , prevent burning and possible losing of fireproof abilitiy because rising temperature.
Q:which kind of material is chosen for fireproofing window?
Firstly, fireproofing window glass must be tempered, ordinary glass won't play a role of fireproofing, and fireproofing window fan is fixed, can't be open, if you can open it, it won't play a role of fireproofing. And you can ask the property to provide texture report of fireproofing windows, fireproof material stipulated by our national fire protection laws and regulations must have fireproofing inspection reports, there must be. and fire window glass should have a fireproofing sign. The main role of fireproofing window is to isolate the fire, and play a role of fireproofing and escaping, avoid the fire quickly spread in.
