Q:What kinds of refractory will be used in kiln of sintering ceramics?
If it is ordinary ceramic, you can use ordinary clay bricks and high alumina brick, adding calcium silicate board, the insulating brick and cotton fiber.
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.
Q:Who knows about the criteria of fireproof and thermal insulation materials?
1. thermal insulation materials with A-level combustion performance: EPS sea capacity module, rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. thermal insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), phenolic aldehyde, gelatine powder polyphenyl granule,etc. 3. thermal insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc. Such A-level insulation materials are only fireproof, the thermal insulation properties are worse than that of organic XPS \\EPS materials. Currently I think that the best insulation material should be EPS sea capacity module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The thermal insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range. I hope my answers help you.
Q:What is the material composition of the new fire-resistant coating?
The basic composition of thick coating steel structure fire is: Binder (Portland cement, magnesium oxychloride or inorganic high-temperature bonding agent), aggregate (expanded vermiculite, perlite, aluminum silicate fiber, mineral wool, rock wool, etc.), chemical additives (modifiers , hardening agent, waterproofing agent) and water. Fireproof coating binders Portland cement, magnesium oxychloride cement and an inorganic binder of the fire-resistant coating for steel structure base material. The conventional inorganic binder include alkali metal silicates and phosphates substances.
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.
Q:Does anyone know what is a lightweight refractory material?
Heat preservation and insulation layer used only for Thermal Equipment has poor wear resistance, loose organization and high porosity(40%~85%) . The definition of light refractory material: low thermal conductivity, good performance in thermal insulation , weak mechanical strength, low volume density(generally below 13).
Q:How to detect the acid resistance of refractory? Is there any standard? Thank you
Setting the acid resistancere of fractory products is simple; R22, two measurement methods are both bricking refractory products, using the mass fraction of the original dry to indicate. It is generally select vitriol as the medium of erosion, such as the international standard determination of the resistance to sulfate of dense shaped refractory products "(ISO8890) and PRE /, grinding fine particles to 0.63 ~ 0.80 mm, and then measure its quality loss, put it in the vitriol with mass fraction of 70%, finally boil 6 h.
Q:Does anyone know fire-proof material of fireproof wooden door?
Fireproof wooden door goes through the flame treatment, so it can prevent fire. Its principle: Fire-retardant treated timber has become flame retardant material itself and its fire endurance has increased. The commonly used method of fire retardant treatment for timber including: Spraying method, soaking method, boiling method, vacuum method, vacuum-pressure method.
Q:The classification of clay according to refractoriness, and what is the plasticity and plasticity index of clay?
Q:Who knows how many kinds of fireproof insulation materials are there in the market?
The so-called A-level materials in fire insulation materials, namely, the WW non-combustible insulation materials, and the WW material s are A-level. Inorganic fireproof and thermal insulation materials can be used as wall insulation materials to replace red bricks, therefore, they, as thermal and cold insulation materials, can reduce the thickness of walls, and save energy, as well as expand applicable areas indirectly, decreased structure weight. They are very good.
