Q:In entering fire door, which material does well?
Now generally do stainless steel.
Q:Which brand of thermal insulating refractory is good?
The most famous is the dragon, Morgan, Luyang, which are good at making ordinary thermal insulation materials and whose products are cheap but quality. Guangdong ALISON nanometer aerogel is more expensive. The heat conductivity coefficient is 0.018. It can work under 1000℃
Q:How to deiron refractory?
It cannot be done in conventional approaches, because you are referring to refractories. If using acid liquor soaking method to deiron, the material itself will be also damaged! If just for reducing the corrosion of materials, it will be OK to add a corrosion-resistant and fireproof protection layer.
Q:What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?
STP has a certain chance to self-destruct. After the sealing layer is damaged, the property will be bothered. When filling the foam glass, burst foam cement and low-strength glass fiber, the structural requirements are very high with big spraying limitations. As everyone knows that rock wool absorb organic matters, and the government do not allow us to use self-insulation, so it is not the mainstream with too low adoption rates. In fact the owners shouldn't worry about this problem. Since the developers have installed it for you, it is useless to worry about it. The other is that for those who want the original balcony closed up, if you want to shovel the original balcony wall insulation, you must pay attention to ask the construction team before you start. Because it is common that the cold bridges formed thereby will cause water seepage and moisture condensation in the balcony.
Q:For refractory, why is it necessary to store the first mixing materials for some time under proper moisture and temperature?
It is mainly to remove gas form chemical reactions in the pug, give full play to plasticity and binding properties of combined, and store unburned brick whose cememting agent is phosphoric acid or aluminium phosphate for some time under proper moisture and temperature. For example, to avoid the formed bricks in the initial stage of drying and firing form cracking due to hydration of calcium oxide. Mixing materials is to store the first mixing materials for some time under proper moisture and temperature in order to improve the evenness and moldability of pud, such as making the distribution of combined clay and water more even. The length of storing chiefly depends on the process requirements and the characteristics of blanks. For the producing pug of high temperature kiln furnitures, the storing time is longer. The function of storing mxing materials varies with different natures of blanks. For honeycomb ceramics, it is to fully digest calcium oxide in blanks. For storing magnesia brick blanks containing much calcium oxide, it should be stored for some time in proper humidity and temperature.
Q:What is the criterion of entry of refractory clay industry?
There are two requirements: (a) Enterprises mining and processing high-alumina clay meet the national industrial policy, and in line with the requirements of mineral resources planning and industrial planning, industrial development planning of high alumina clay in provinces (autonomous regions and municipalities), urban planning, the whole land use planning, mineral resources planning, environmental protection and pollution prevention planning. (b) The building of new mines of high alumina clay in areas where exploitation of mines are restricted in national and local level should be strictly limited. It is prohibited to build new mines in areas where exploitation of mines is banned, and the mines have been built should be disposed in accordance with the mineral resources planning and relevant national regulations. It is prohibited to build high-alumina clay production and processing enterprises in special conservation areas such as drinking water source reservation areas, natural reservation areas, scenic reservation areas, ecological function reservation areas, basic farmland reservation areas, cities and their suburbs, residence, schools and kindergartens, health center, hospitals and perimeter 1 km from enterprises having high requirements on the environment such as food, medicine, electronics etc., the both banks of main rivers and roads, somewhere near trunk railways.
Q:What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?
There are two kinds: 1, the thickness of the plate is between 20 ~ 50 mm with composite structure 2, sheet thickness is between 6 ~ 15 mm calcium silicate fire prevention board.
Q:What are the features of construction class A fire resistant door ?
1, Save space and reduce cost. Feature of Nanjing Cathay Class A external wall thermal insulation materials : the thickness is between 60mm--180mm, so compared with the traditional block thickness, it saves architectural space greatly. At the same time, the weight is only 1/10 of that of the traditional wall, thus reducing coast in terms of architectural structure. 2, Fireproof and green. Features of Nanjing Cathay class A fireproof external wall thermal insulation materials: fire endurance under high temperature of 1000℃ is 4 hours, and non-combustible performance can reach state A level, without any toxic gas in full compliance with international environmental standards. 3, Waterproof. Features of Nanjing Cathay Class A fireproof external wall thermal insulation materials: no slightest leakage when it is being used in containers for water without any waterproof finishing. It can be used in kitchens, bathrooms, basements and other wet areas. 4, Sound insulation. Features of Nanjing Cathay class A fireproof external wall thermal insulation materials: internal materials and EPS polystyrene foam granule have good properties of sound insulation and sound absorption. 90mm-thick wall can insulate 40dB sound, in line with national standard of sound insulation for residential building. 5, Thermal insulation. Features of Nanjing Cathay Class A fireproof external wall thermal insulation materials: main raw material is frezing resistant and thermal insulating material which is environmentally friendly and energy saving. With good effect of thermal insulation, it can keep indoor temperature at a constant level, so as to make the environment more comfortable.
Q:What are the disadvantages of the refractory industry?
The rapid development of continuous casting technology allows Hua Heng refractories to be improved in variety and quality. The development of refractory for continuous casting has a significant impact on the production of continuous casting and quality of continuous casting billet. Constructing and putting Baosteel into action has greatly pushed the improvement of the refractory technology. Continuous casting refractory is an important part of the continuous casting machine. In addition to the general characteristics of refractories, it is also required functions that can purify molten steel, improve the quality of steel, stabilize temperature and composition of the molten steel, control and regulate the molten steel flow. Therefore, it is known as functional refractories. Continuous casting Refractories include: (1) ladle refractory - ladle lining, permanent lining and ventilation components; (2) tundish refractories - permanent lining, coating, insulating plates, clad etc; (3 ) functional refractories - long nozzle for non-oxidizing casting, submerged nozzle, monolithic stopper, sliding gate; (4) ceramic purifier for purifying molten , slag dam, alkaline paint and horizontal separating ring and gate board for continuous casting.
Q:What's the difference between refractory metal raceway and fireproof raceway?
Hello, I'm very glad to answer your question. As far as I know, anti-fire groove box is made by the polymerization reaction of high polymer material and halogen-free flame retardant polymeric material. It possesses excellent mechanical properties and environmental protection property, nice appearance, and diversified colors. As a kind of fully enclosed cable bridge, it is applicable for communication signals, and laying of computer cables and control cables of highly sensitive systems. When used in heavy corrosive environment and outdoor dust environment, it has good protective effect on cables. It boasts many advantages of fire retardance (fire resistance rating is above B grade), corrosion resistance, anti-aging, high strength, light weight, and easy installation. Hope my answer is helpful for you. Hope my answer can be accepted.
