Q: How about the prospect of refractory material?: is developing well. Many plants are required t o use fireproofing materials.

Q: Who can tell me what is neutral refractory?: Neutral refractories refer to the refractory materials which will not react greatly with both acidic and basic slag at high tempreratures. Such as carbon refractories and chromite refractories. The main components include carbon, silicon carbide, aluminum oxide, chromium oxide and other trivalent oxides, such as carbon refractories and chrome refractories, etc. Strictly speaking, neutral refractories refer only to the carbonaceous refractories, including carbon brick and graphite silicon carbide products, etc.

Q: Do you know the refractories?: The so-called main component refers to the first phase and the second phase component, and the content accounts for about 90% of the total chemical composition. The development of modern technology more and more number of refractory material ingredients, so the second phase, the third phase component, adjusting the second phase, the third phase composition can generate a new technology in the chemical composition of the first phase beyond the limitations of the classification, a classification method is the most commonly used.

Q: Does anyone know what kind of light fireproof materials are there?: 二, 1, Gypsum plaster board With the building plaster as main raw material, gypsum plaster board is a kind of processed plate made by a special board for protective with an addition of additives and fibers as board core. Gypsum plaster board is characterized by light weight, sound insulation, heat insulation, strong processing performance and simple construction method. 2, Gypsum block Gypsum block is a kind of lightweight building gypsum product which is mainly made of building gypsum, and by adding water, stirring, casting and drying. During the process, , the fiber reinforced materials or light aggregates are allowed in, and the foaming agent can also be added. It has many advantages, such as sound insulation and fire prevention, convenient construction and so on. It is a kind of new and healthy wall material which produces low carbon, enhances environmental protection, and caters to the the times. 3, Fly ash brick is a new type of wall material, and bulk density is one of the main technical indexes. The weight of bulk density can be controlled according to the need of construction and adjustment of technical formula. The dry bulk density of the fly ash brick is about 1540 to 1640 kg / m 3, slightly lighter than the clay brick (1601800 kg /m 3). The flexural and compressive strength of fly ash brick is mainly determined by the production process, the formula and the hydrothermal synthesis reaction mode as well as the need of construction. According to the standards of architectural material industry (JC239 - 2001) released by People's Republic of China, the average value of the flexural strength is 2.5 ~ 6.2Mpa, compressive strength is between 10 ~ 30Mpa. I hope this will be helpful to you

Q: About the market issues of thermal insulation material and refractory material.: In fact, the thermal insulation material produced by the Sichuan-Benniao Hing construction company is very good, you can get the company's information just by inputing the Sichuan-Benniao Hing construction company into Baidu

Q: How to determine the fire resistance rating of the aluminium-plastic?panel?: Fire rating of the best aluminium-plastic?panel in the current market is B1 class, and its grade classifications can refer to the national standard. I have examined factories and tested the fireproof effect of the fire-proof plate myself by burning it, and I have found that the fire-proof plate of Jinwei Aluminium-plastic?Panel in Linyi is really good in quality and fire prevention. In other words, from the single point of fire rating, the corresponding fire rating of the called fireproof aluminum (plastic) composite panel should be at least B class, and for A2 class fireproof aluminum composite panel, its core material currently doesn't include plastic element, so it's called aluminum composite panel which is of inorganic core material. If the ordinary aluminum-plastic panel is classified according to the fire-proof building material, it will belong to that of lower level. For aluminum-pastic panel used in business premises, it is required to reach the grade of flame retardant material or above this in fire prevention. It is expressly stipulated that its fire rating should be A2 class in public places.

Q: What are the technical requirements for refractories?: To put it simply, physical indicators are pores, volume density, pressure resistance, slag resistance, thermal shock resistance, foot expansion coefficient, thermal conductivity, oxidation resistance and so on. If it is castable, the indicators are mobility, water rate, setting time, and anti bending strength. If it is coating mix, the bonding strength should be checked. Chemical indicators are loss of ignition and the content of aluminum, magnesium, silicon, calcium, chromium, titanium and carbon.

Q: What is the definition and classification of amorphous fire resistance materials?: 9.8. brick made of refractory bone material and powder material can be used directly or after adding appropriate liquid formulation Refractory paint. Refractory slinging material 6. Prefabricated cubes, bonding agent or other additives. fire-resistance sparying material compround additives. Refractory pressed into the material, binder. Refractory ramming material 3, The material is a new fire proof material without calcination Heavy aggregate and lightweight aggregate: Inorganic binding agent and organic bond, its fire resistance is not less than 1580. Refractory castables 2 mouldable refractory Classification according to the type of bonding agent: 1. Classification according to refractory aggregate. According to the production and construction method, refractory mud or refractory mire, with a certain proportion of the mixture

Q: I wanna ask what are the acidic refractories?: (1) silica?brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity.

Q: What are the differences between intensive refractory busway and other busways?: Compact busway is named according to its structure, and fire-resistant busway is named after its uses. Compact busway especially refers to busway which is closely laminated between phases and between phase and shell, and use thin insulating material to achieve the insulation result. suitable for power supply system of alternating current three-phase four-wire, three-phase five-wire system, frequency of 50 ~ 60Hz, rated voltage up to 690V, rated operational current of 250 ~ 5000A, as auxiliary equipment for mining, enterprises and high-rise buildings, and especially suitable for the transformation of workshop and old enterprises. Fire-resistant busway is composed of shell coated with fire retardant paint, bus line wrapped with fire-resistant mica tape and bracket made by refractory insulating material. Bracket has a plurality of grooves where inbedding the bus line and fixed it. There is a busway connecting box at one end of the busway and there is a bus line splitter box in the busway. Fire-resistant busway has excellent insulation properties, which can not only be used continuously in a normal environment, but also can be used in the fire environment continuously for more than one hour, suitable for high-rise buildings and important facilities, replacing the fire-resistant cables to transmit and distribute power .
