Q:Can quantitative feeder be used in refractory plant? Thank you
Feeder experts, justice and analysis, quantitative feeder, of course, can be used in refractory plants
Q:How long usually will the A-level fireproof materials prevent the flame?
A-level fireproof materials refer to the materials which are made of non-combustible materials, it is a different concept from fire resistance. non-combustible elements: Components are made of non-combustible materials. Non-combustible materials refer to materials that will not burst into flame, and burn as well as be carbonized when affected by fire and high temperature in the air. Fire resistance: Having a fire resistance test on any building components -----according to the standard time-temperature curve. This period starts from the time when affected by fire and ends up with losing the ability to support or to insulate fire or the integrity of the components. It can be expressed in hours.
Q:Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?
1.The insulation materials with A-level combustion performance: EPS Hairong module, rock wool, glass wool, foam glass, ceramic foam, foam cement, closed-cell perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powder particles,etc. 3. The insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene boards(XPS), Polyurethane(PU), Polyethylene(PE), etc. See the 2009 measures of building technology. The A-level insulation material is only fireproof, the insulation performance of it is worse than that of organic XPS \\\\ EPS material. Currently I think that the best insulation material should be Hairong EPS module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range.
Q:Do you know where I can buy refractories?
You can buy refractories in these places: 1. Addresses of refractory factory: No. 57, Qingshan District, Wuhan 2. Address of Qingshan refractory factory in Wuhan: Special NO.1 Xingli Road Hongshan District, Wuhan 3. Address of Xinghuo refractory factory in Hongshan district: No. 34 Qingshan District, Wuhan 4. Address of Henao refractory factory: No. 78 Jiangxia District, Wuhan
Q:How to divide fire rating of decorating materials ?
I am very happy to answer this question for you. It can be divided into Level A: noninflammability; B1: difficult-flammability; B2: combustibility; B3: inflammability. I hope my answer is helpful to you, thank you.
Q:What refractories can withstand high temperature above 2100 degrees?
But the price is more expensive, while the insulation performance is not as good as common materials. Is there a material that can withstand 2100 ℃? Currently, the long-term use temperature of the best refractory bricks is about at 1800 ℃, while materilas that can withstand a temperature of 2100 ℃ are relatively rare in the production.
Q:What is refractory cement?
The introduction of properties and chemical composition of refractory cement. Refractory cement usually refers to the cement with calcium aluminate as the mian compopnent. Refractory cement is a monolithic refractory. It is in particular a basic binder of castable refractory. Its chemical composition is mainly Al2O3 and CaO, and some contain a considerable number of Fe2O3 and SiO2.
Q:What advantage and disadvantages it has compared to common fire insulation materials
Generally speaking, high fire resistance, non combustible Various standards for evaluation varies according to different types, which includes anti-corrosion, acid and alkali resistance, waterproof, anti termites and so on. I hope my answer can slove your problem
Q:What is the main material of fireproof wooden door?
Fireproof wooden door has a lot of materials! including imported timber decorative effects: utilizing the diversity and easiness to cut of the timber, with all the decorative characteristics of the timber. Material selection features, door frames: Using high-quality hardwood, such as imported miscellaneous wood, camphorwood, lauan, hemlock, etc., insetting fire and smoke proof adhesive tape
Q:As for fireproofing material rock wool and glass wool, which one is better?
Rock wool board and glass wool board are a kind of new construction thermal insulation material, it's widely applied in construction and has replaced traditional thermal insulation material to some degree. With the gradually deepening study of rock wool board, glass wool board, we can find that these insulation materials have advantages in many aspects but there are also many deficiencies, particularly there exists a lot of controversy about the impact on the human body. The production process of rock wool board and glass wool board usually includes: after melting in high temperature of rock or glass, inorganic fiber is produced by high-speed centrifugation equipment, and at the same time add binder,dust laying oil,silicone oil at certain proportion, then produce sheet material according to different requirements. It has good thermal insulation properties, mechanical property, sound absorption characteristics, belong to incombustible material and is cheap. In general, insulation, security and economy should not be contradictory, three aspects should be taken into account, balanced chosen and developed. Rock wool board and glass wool board and other such materials should be properly selected and applied to the appropriate structure, so that the choice of material will play their strengths and avoid their weaknesses.
