- Q: What are the use of fire-resistant material and admixture?
- Generally speaking, there are several admixtures: 1. Water reducing agent. It can ensure basic refractory castable flow value and significantly reduce its water mixing amount sodium hexametaphosphate and sodium tripolyphosphate 2. Plasticizer. It can increase plastic refractory mixture and enhance the ability of bentonite clay mud material stress strain 3. Gelling agent. It can make the colloidal solution (or suspending liquid containing solid particles condensed gelling agent 4. Dispergator. It can turn condensation or reunion colloidal particles (particles) into sol or uniform dispersion suspended particles and make the thick colloid free stream sol said scattered coagulant peptizer 5. Coagulant. It can shorten the stereotypes refractories condense sclerosis NaOH Mars between aluminum hydroxide, etc. 6. Retarder. It can delay the stereotypes refractories condense sclerosis between citric acid tartaric acid, etc. 7. Delayed coagulant. It can make setting fire-resistant materials contain binder by set out the condensation hardening effect between calcium aluminate cement, etc. 8. Foaming agent. It can reduce the liquid surface of power to produce uniform stability as rosin soap bubble resin fat saponin and so on. 9. Antifoaming agent. It can make fast setting fire-resistant material mixing or shock in produce bubbles escape alcohol fatty acids, such as 10. Shrink agent can reduce or prevent the refractory materials used to produce contraction type heating said silicon powder stabilizer or volume expansion agent, etc. 11. Preservative. It can keep setting fire-resistant material stored on construction performance change or change oxalic acid citric acid, etc. 12. Inhibitors. It can inhibit stereotypes refractories ingredients contain iron or iron compounds and acidic reaction caused inflation to produce hydrogen bond CrO3 diacetone alcohol, etc. I hope it can help you.
- Q: What is acid refractory material?
- In fact, with the content of zirconia refractory multiple theory should also be acid refractory
- Q: How is the division of the fire resistant level of the rock wool board?
- It's like this: China's national standard GB8624-97 divides the combustion performance of building materials into the following grades. Level A: non-flammable building materials. Level B1: flame-retardant building materials. Level B2: combustible?building?materials. Level B3 flammable building materials. section II Combustion performance and fire endurance of building components. First, The combustion performance of buildings of building components. The building is composed of components, such as foundation, walls, lubrication columns, beams, plates, roofs and stairs, ect. Building components are constituted by the building materials, whose combustion performance depends on the combustion properties of the used construction materials. Section One Combustion performance of building components. The building components are divided into three categories according to their combustion properties. First, non-combustible component: the component made by incombustible?materials. The incombustible?material refers to that when meeting the Oxygen in the air, it will not burn.
- Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- Solid wood logs are necessary. If it is the type of smoke free material, it will not be necessary. You'd better confirm it with the port of destination. Vietnam has the requirement to smoke
- Q: What is the difference between wear-resistant material and refractory material?
- There must be difference. The requirements of refractory material are that it can be called refractory material when temperatures it can withstand are over 1570 ℃. Refractory material must have high strength. The specific value of refractory material is not clear.
- 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: What types does soft fire prevention materials have?
- Types of fire resistant species. Mainly listed as follows: finishing fire retardant paint, component fire retardant coating, fire-resistant coating for steel structure and othe kinds of fire retardant coating. Flame retardant plastics and its products, textiles, building materials, flame retardant fabric and exterior wall thermal insulation system products, floor materials, such as various types of fire prevention materials;Fire prevention board, fire doors, fire prevention, fire shutter, fire glass window frame, elevator doors, ventilation pipes, fire blocking material, fire smoke exhaust fan and other kinds of artifacts (resistance) fire prevention. Indicators of judging fire mainly include: difficult to fire, ignition, smoke toxicity, smoke density, heat release and flue gas; fireproof performance, combustion performance and combustion heat value, fire resistance, high temperature resistance, fire rating, etc. And some specific parameter is needed to use professional testing instrument to judge, but to the inorganic lab for understanding, fire prevention level test result accuracy.
- Q: Firing high temperature kiln of refractory and internal temperature being as high as 1600 ℃, metal heat exchanger can't use, how to do?
- 1>3>。 When metal heat exchanger is in 700 ℃, it must process high temperature protection, mixed cold wind or cold blast to protect heat exchanger. So this will waste a lot of energy; The comparison of high temperature resistant ceramic heat exchanger using temperature is 1350 ℃ to 1450 ℃; metal heat exchanger using temperature 700 ℃; heat utilization comparison of ceramic heat exchanger can be placed in 1350 ℃ or higher (highest available to 1450 ℃); the oxidation resistance, a very short time will burn out;2 >, waste heat recovery rate is high. Replacing the metal heat exchanger in high temperature and corrosion environment; Comparative ceramic heat exchanger can be used under the condition of 1350 ℃ for a long time. Let's make a comparison, if it is a refractory material industry. <, ceramic heat exchanger is simply won't appear, under the condition of equal to ceramic heat exchanger using, energy saving effect is best, can exchange for the high temperature. <. Ceramic heat can be placed on the nearest of exchanger flue outlet . <, and metal heat exchanger put in place contrast to the ceramic heat exchanger. In the process of using metal heat exchanger, if this situation happens, you can consider the ceramic heat exchanger. Temperature difference is between 650 ℃ to 750 ℃. If the metal heat exchanger is placed in normal place where ceramic heat usually put;The service life comparison: since ceramic heat exchanger with high temperature resistance, this partly replace metal heat exchanger. What's more, energy-saving rate is also different. Metal heat exchanger can be placed in 700 ℃ or less;4 >, corrosion resistance, its application effect is very different. So the metal-heat-exchanger's heat-resistant temperature is high and the service life is the countless times of metal heat exchanger. The place with highest temperature does not need high temperature protection.

- Detailed address of fire insulation materials market is as follows: A: Guangzhou Huatai building materials co., LTD. Address: Guangzhou Tianhe Chepo Road no. 10 B: Address of Donglong building materials market: Guangzhou Tianhe Taian North Road no. 7 C: Address of Huiya building materials trade market : Guangzhou Tianhe Sports West Road No. 109
- Q: What refractory materials are used in power plant
- Vacuum mud machine, sintering furnace! And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)
