- Q:Which kind of external wall fire barrier zone material is better?
- I recommended foam cement and particulate thermal insulation composite waterproof material, which is fire isolation area product, which uses surface of vertical?plate arranged fiber technology to make the compressive?strength in the vertical direction up to above 80KPa. At the same time, under the conditions of both exterior heat insulation and effects of humiture in the long-term, it can still maintain the non-aging performance of various aspects, and safety (reliability), fire resistance and excellent durability.
- Q:Detailed description of magnesia dolomite refractory material?
- The use of low chromium or chrome free refractories is more and more widely used, developed countries in the development of chrome free refractories to replace the chromium containing material, through research and production practice show that dolomite refractories is the refining of AOD furnace, large cement kiln ideal material.
- Q:Which are fireproofing external wall materials?
- For example, Grade-A waterproofing external wall thermal insulation material: glass wool, foam glass, foam cement, hole-closed perlite, rock wool; Grade-B1 waterproofing external wall thermal insulation material: XPS after special treatment. There are also PU after special treatment, phenolic aldehyde and gelatine powder polyphenyl granule. Grade-B2 waterproofing external wall thermal insulation material: PE, and EPS. Grade-A: Completely fireproofing buliding material. Without probility of burning, completely fireproofing buliding material is expensive and unnecessary for home decoration. It is usually used in arsenal and electrical equipment department store. Grade-B1: nonflammable building material: With good flame resistance, nonflammable building material will not burn in the air or at high temperature, but it maby burn in the air and at high temperature. But when the fire source ransfers, it will be out immediately. Grade-B2: combustible building materials. Due to its small firresistance, it is easy to burn in the air or at high temperature, such as wooden building materials. The above are external wall fireproofing material of different classes.
- 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:I know which material is the fire resistance rolling shutter door
- Fire resistance rolling shutter door and ordinary roller shutter are basically same, the differences are: Its inner and outer sides are generally made of galvanized iron sheet, filling asbestos fireproofing material betwwen two layers of fire resistance rolling shutter door, and some fire shutter doors can be interlocked with the relevant fire control system, when the breaking out of fire , it can automatically "half-drop" and "full drop".
- 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:Does the production of refractory belong to advanced technology？
- Refractories belong to the area of new materials which is one of the eight areas that are supported by the state. Whether it can be declared as high-tech enterprises or not depends on the intellectual property, personnel and finance of the company.
- 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:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
- 2, form Mg-SiO2 coagulation and combination, CA cement bond? Bricks can generally be made by combing with phenolic resin, castable use 1, combined with silicon powder; 3, can also combined with brine MgCl is binding agent
- Q:I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?
