- Q:What are the types of refractory sealant?
- Refractory sealant has low exothermicity and will form a hard corking content during burning, it includes: Liquid polysiloxane has at least two active groups selected from alkoxy, hydroxy and alkenyl; a cross-linking agent, a catalyst, a reinforcing filler and wollastonite. These cured silicone rubber sealant has low heat release and will form a hard coking content structure while buring. Refractory sealant composition can be used in sealing structure to prevent flames, air and other steams passing. 1. In a liquid organic polysiloxane polymeters, each R1 is independently selected from the alkyl, aryl, alkenyl and haloalky which has 1-18 carbon atoms, and each R2 is independently selected from the hydroxy, alkoxy, alkenyl, and X is an integer from about 10 to 1,500. 2. A crosslinking silicone compound having at least 3 silicon-bonded eactive groups. 3. A R2 pressed of silicon bonding capable of promoting component A. 4. Wollastonite and a selective reinforcing filler.
- Q:Who knows the external wall thermal insulation materials fire rating requirements?
- The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height
- Q:What's the fire endurance of hollow brick?
- Light weight, high strength, thermal insulation, sound insulation and noise reduction. environmental protection, no pollution, the ideal filling material of frame structure building, Disadvantages:: poor seismic performance, fire reistance being less than 1000 ℃.
- Q:Is it normal for caable fire resistant material to catch on fire?
- Abnormal, preventive measures: 1 take fire preventive measures. Measures taken for fire retardant measures of cable: (1) seal closely with fire resistant materials holes ran by cables through walls, shafts to prevent the cable fire, high temperature gas diffusion and spread when cables are on fire. (2) to wrap the cable with the insulation refractory material, when the cable is surrounded with fire, warpped cable is insulated by the insulation material from fire, so it will not be burned. If the cable itself is on fire, fire will be extinguished thankes to lack of oxygen in warpped cable, to avoid the fire to spread out. 2 to strengthen the cable circuit switch and regular protective check and maintenance, to ensure that the action is reliable. 3 to strengthen the cable operation and monitoring, to avoid the overload of the cable operation. . 4 regularly clean dust on the cable, to prevent cable from catching on fire due to the accumulation of dust. 5 to ensure the construction quality, the quality the cable must be strictly in line with the requirements and standards. 6 cable laying should maintain enough distance form the heat pipe, control cable is no longer than 0.5 meters; power cable is no longer than l meters. Control cable and power cable should be divided into slots, be layered and seperated instead of being overlapped . For the parts that do not meet the requirements, measures must be taken to insulate heat and fire. 7 regularly teat cable , abnormal problem should be handled in a timely manner. 8 install fire alarm so that fire will be discovered on time, and cables will not catch on fire. 9 the cable trench should be kept dry to prevent the cable from being affected with damp, or leading to declined insulating function and short circuit.
- Q:What is the function of refractory material?
- Refractory is a basic material in the field of high temperature technology. Generally, the refractory is used as structural material or lining to resist high temperature in various thermal equipment and high temperature container. In the iron and steel industry and metallurgy industry, coke ovens are mainly composed of refractory materials. Various refractories that meet the requirements are essential in blast furnace for ironmaking, hot stove, all kinds of steel-making furnaces, soaking furnace and heating furnace. Not only the die casting for molten steel needs lots of refractory materials, but also the continuous casting needs some high-quality refractory materials. Without high-quality refractory materials, external refining is also not impossible to achieve. Statistics show that the steel industry is the sector that needs the most refractory. Pyrometallurgy and thermal processing of ferrous metal also needs refractories. All high-temperature furnaces or lining in construction materials industry or other high temperature industries that produce silicate products such as glass industry, cement industry, and ceramics industry must be constructed with refractory materials. All kinds of roasting funaces, sintering funaces, heating furnaces, boilers, flues, chimneys and protective layers in chemical, power and machinery manufacturing industry need refractories. In short, when some kind of structures, devices, equipments or vessels are used under high temperature, they all should utilize refractory to resist the high temperature because those materials will deform, soften and fuse or will be eroded, scoured or broken due to the physical, chemical, mechanical effects, which may stop the operation, affect the production, contaminate processed objects and impact the quality of products.
- Q:How to distinguish the fire resistant level of construction materials?
- Building materials fire resistant level is divided into four levels, among which the first level is the highest, with strongest fire resistance; fourth level is the lowest with weakest fire resistance. Fire resistance level of buildings depends on combustion performance and fire endurance of the building components. The building components refer to a series of basic components such as the building walls, foundations, beams, columns, floors, stairs, ceiling, etc.
- Q:How to solve the shell, the crack problem of refractory material in the process of forming.
- Pressure mode and number of pressure control "spallation". 2, multiple pressure, pressure degree and discharge way: 1, reduce friction, choose appropriate, than big pressure disposable pressure produced by the plastic deformation, allocate reasonable grading, internal and external friction, reduce billet particles and high die wall bright. 4.--- solve the light one firstly. --moisture content being too high easily cause spallation - the compressibility of water is small and have certain elasticity, appropriately to extend the pressuring time is beneficial. The material can produce large plastic deformation under the effect of continuous load. The right amount of lubricant. - body under the condition of less pressure but long effect time molding. Mould structure is reasonable and improve billet natural stacking density. 5.3, measures to improve the unburned brick molding quality. Many times continuously pressure relief is better than one-off sudden unloading, and controlling the appropriate moisture content;- - is beneficial to air overflow.
- Q:how long is the fire endurance of plasterboard?
- Plasterboard is non-flammable B1 level products. There are introductions in Fireproof Specification of National Standard Building Interior Decoration Design. Plaster board mounted on steel stud can be used as A level decoration materials. In accordance with the national fire safety rules on fire durance of walls and ceilings and other components, we can not simply say whether a piece of gypsum board can meet the requirements. In GB "gypsum board" it clearly states: Fireproof plasterboard can endure fire longer than 20minutes. Wherein Dragon brand fire-resistant gypsum board can endure fire longer than 40 mintues. Gypsum board is comprised of dry wall, steel stud and various auxiliary materials. the fireproof performance of the gypsum board system is relevant to the type, quality , layers of the gypsum board, quality of keel and installations, whether the rock wool is filled and its unit weight, the treatment of seaming and some minor joints.
- Q:How to prolong the furnace age of Induction furnace by using fireproof materials?
- magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.
