- Q: How is the division of the fire resistant level of the rock wool board?
- The fire rating of European style rock wool board is level A , which uses Da Guang Beijing Jinyu rock wool board, with the main advantages are: 1, High acidity coefficient: The high coefficient of acidity greatly improves the life resistance and weather resistance of the rock wool board. 2, Hydrophobic air permeability: According to the picture, Jinyu Star rock wool is water-repellent, at the same time it also has breathability, so the liquid water is not easy to dip into the rock wool, and the water vapor and other gas molecules could pass through the rock wool. In particular, the insulation materials have this feature which enables the building to have "respiratory function" thus making the room more comfortable and preventing anti-mildew phenomenon happening indoor. 3, Environmental protection: The goldfish can survive freely, which just shows it is environmental; 4, High strength: The advanced pleating and curing technology make the rock wool board tensile and high compressive strength. It not only can be applied on the external wall thermal insulation and sandwich board core material, but also can be used to make structural cotton in the flexible waterproof roofing. Its quality is so stable that it is convenient in construction and durable in use. 5, Fireproofing: Not just talking about the fire rating, but the fireproofing time, which is generally up to two hours, and can be used for lining thermal insulation fire-resistant part of the glass curtain wall, through-wall pipe seal, pier?between?two?windows, window sill wall and other parts; 6, Derived advantages: Agriculture applies the soilless cultivation cotton;
- 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: which kind of material should be used in fireproofing cabinet?
- Here are a few good materials: 1. The mineral wool board, glass wool board: it mainly tales mineral wool, glass wool as insulation materials. It's non-combustible, light weight and has good high temperature resistance, but there are shortcomings ① short?fiber will harm the human respiratory system, ② poor sheet strength, ③ poor barrier property of sheet for smoke of fire disaster, ④ poor decorative properity, ⑤large installment and construction work. Thus, most of the boards were sheets that take inorganic anchoring material as base material, glass wool as reinforcing material. 2. cement board: Cement board has high strength and wide sources. It is often used in fireproof suspended?ceiling and partition in the past, but it has poor fire resistance and is easy to burst and lose protective function , which will limit it's applications. Cement concrete component has good thermal insulation and sound insulation properties, and it can be used as partition and roof board. Fiber reinforced cement board and other improved varieties appear in the construction?materials market, and they are high strength and have good fire resistance, but their disadvantages are poor toughness, large alkalinity and poor decoration effect. 3. perlite board, cenosphere board, vermiculite board: It's a kind of hollow plate that takes low alkalinity cement as base material, perlite, glass beads, vermiculite as the aerated filling material, and is made by adding some auxiliary. It has characteristics of light weight, high strength, good toughness, fireproofing and thermal insulation, easy for construction,etc. and it can be widely used in high-rise building frame compartment, household, bathroom, kitchen, communication pipe and other non-load bearing areas.
- Q: What do refractory materials include?
- What refractories are included? Refractories include AZS brick, corundum brick, direct-bonded?magnesia-chrome, carborundum brick, silicon nitride bonded silicon carbide brick, non-oxide refractory materials such as nitride, silicides, sulfides, borides and carbides, oxidation calcium, chromium oxide, aluminum oxide, magnesium oxide and beryllium oxide.
- Q: Can refractory be used as sealing element?
- It can. For example, fiber ceramics can resist high temperature! !
- Q: What types of steel are silicious quicksand and chromium quicksand used in respectively?
- Chromium quicksand can be used in steel-making process that has longer refining time like LF, VD and RH, in stainless steel drainage and thin plate drainage agent. Silicious quicksand is used in short steel-making process, process that is less than 45 seconds or process without refining. You can consult Hua Heng for details or inspect it by yourself.
- Q: Who knows about the B-level fireproof insulation materials?
- Commonly used B-level materials: Molding polystyrene foam, extruded polystyrene board, gelatine powder polyphenyl granule heat insulating slurry. Although the polyurethane is not the commonly used material, but the 9mm composite of monolayer gypsum board and PU insulating material can reach B-level.
- Q: What are the refractories for converter?
- Analysis of refractories are as follows: MgO-C brick converter Dongxin refractory furnace cap, steel tapping hole, shaft, shaft, pool, air brick
