Q:About the market issues of thermal insulation material and refractory material.
After all, most people have the characteristics of being accustomed with something and it will not change easily ; second, the South has few material manufacturer, but in the Northeast, there are thermal insulating and refractory material manufacturers, which is in shortage, however, but irt is in the minority, and in many areas it is not suitable for exploitation of mineral (due to heavy industry and agriculture land and other reasons). I hope that my answer will help you. first, in the Northeast, the refractory material is not very rich, but the thermal insulating and refractory material demand is very large; third; fourth, which material is used more relived, after all, we should take the transportation costs into account, and it will depend on the kilns construction engineers being willing to use which kind of material, and the thermal insulation material procurement in northeastern region is mostly from the north.
Q:Who knows the highest temperature the high-temperature refractory coating can resist?
When coating the fire-resistant coating on a steel beam of a building, paint film thickness reaching 2mm, and steel beams in the building are on fire, the fire-resistant coating can withstand for two hours. Fire-resistant coating is passive fire protection materials painted on the surface of the protected objects (eg. steel structure) , which can be divided into types of thick, thin, ultra-thin and facing according to the thickness. It can be divided into water-based and solvent-based products by medium. Whatever the structure of the building is, it will collapse if it is on fire for a long time. Fire-resistant coating function as isolation layer on the surfaces of the protected objects, delaying the building collapse time to win over valuable time for rescue and fire fighting. I hope this answer can help you.
Q:What is the difference between the fire rating and the fire resistant level of the fire-fighting equipment?
Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. Fire resistance rating of the building is divided into four levels. Standard of fire resistance rating is determined by the combustion performance and fire resistance of the main housing member. Level one or two are in accordance with the Article 1.0.2 in this specification.
Q:Do you know what the main indicators are for the inspection of refractory materials? Thank you very much for your requests and reports
The main indicators of refractory material inspection must be fire resistance materials, flame retardant, a subdivision of lecture, ignite the smoke toxicity, smoke density, heat release and flue gas;
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:What is carbon composite refractories? I hope that the answer is in detail.
Q:Does the production of refractory belong to advanced technology?
Refractory is traditional ceramic material. We can only say that national development is relatively backward. If the refractory is counted as new material, then it still has huge development potential.
Q:What is the acceptance standard of refractory?
Feeler gauge is used to check the thickness of the refractory brickwork joint. The top of the gauge can not be sharpened. Feeler gauge is of the width of 15mm, length of 100mm and thickness of 1, 1.5, 2 or 3mm. The thickness is eligible when the depth which the feeler gauge is inserted in is less than or equal to 20mm. Ten places should be inspected per 5m2 of masonry surfaces. It is qualified when the condition in which thickness of the brickwork joint is 50% larger than a predetermined depth is not less than five times and it is excellent when the condition is no more than two times.
Q:How is grade of fire endurance divided?
Level of the building is classified according to the importance, fireproofing, durable life and etc. different angles. Civil buildings are classified according to the following ways: 1, It is divided into five grads according to its importance: A, AAA level: Buildings with great memorial, of historic, international and national level. B, A level: High-grade residential buildings and public buildings. C, B level: Intermediate residential buildings and public buildings. D, C class: Ordinary residential buildings and public buildings. 2, It can be classified into four types according to the fireproof performance: Fire resistance level of the buildings is divided into four levels. Standard of fire resistance level is decided based on the combustion performance and fire endurance of the main components of the building. 3, It can be classified into four levels according to the durable life: A, A level durable life is more than 100 years. It is applicable for important buildings and high buildings. B, B level has a endurance for 50 to 100 years and it is applicable for ordinary buildings. A, C level has a durable life of 25 to 50 years. It is applicable for less important buildings. B, D level has a lasting year of below 15 years and it is applicable for temporary buildings.
Q:What's the classification of flameproof glass, the refractory time of fireproofing glass.
According to different manufacturing technique, thermal insulation fire-resistant glass can be divided into grouting fireproof glass and composite fireproofing glass. Grouting fireproof glass has good thermal insulation performance, composite fireproofing glass has good fireproof performance.
