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.
Q:Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?
There is no necessary connection between them. Different fire resistant ratings of bulidings require different fire endurance of different elemements of buildings. According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level. "Building Regulations" mention that fire resisting shutter can be used as partition of fire compartment in those places where setting firewalls is not so easy. When using fire resisting shutter whose fire endurance doesn't include unexposed surface temperature rise, it should install closed independent automatic sprinkler system for protection on both sides, and the sprinkler sholud last at least 3 hours.
Q:Which one is better, fire-resistant wood or steel?
According to my understanding. This fire-resisting wood is better. Iron birch. The iron birch is three times harder than the oak, twice as hard than ordinary steel. It is the world's hardest wood which is used as a substitute for metal. The Soviet Union have used iron birch for the manufacturing of roller ball, bearings and it is applied in yachts. Iron birch has some wonderful characteristics. Since it has very dense texture, once put in the water it will sink; even if it is soaked in the water for a long time, the inside still remains dry. The iron birch is twice harder than the steel, it doesn't mean that its hrc value is twice of that of the steel. HRC means test load 1471.1N (150KG-F) using a diamond cone head with the point angle of 120 degrees to press. The calculation formula HR= (K-H) /C,K=0.2MM,H is the depth of indentation after releasing the major load. C= 0.002MM, so HRC100 is a limit value, then H is 0, which means that even the diamond will not drill into it. Generally the hardness of bearing steel is about HRC60. Iron birch is the championship among trees in terms of hardness. The bullet hit the wood is like hitting on a thick steel plate and the wood will be motionless. So, it is known as a tree harder than steel. I hope my answer will be helpful to you.
Q:About the market issues of thermal insulation material and refractory material.
In fact, the thermal insulation material produced by the Sichuan-Benniao Hing construction company is very good, you can get the company's information just by inputing the Sichuan-Benniao Hing construction company into Baidu
Q:What is the fireproofing requirements of external wall thermal insulation materials?
External wall thermal insulation materials fire rating regulations, 1, the height of a building is greater than or equal to 100m , the combustion performance of insulation materials should be level A; 2, the height of a building is greater than or equal to 60m but less than 100m, the combustion performance of insulation materials should not be less than the level B2. When using level B2 thermal insulation material, every layer should set horizontal fire barrier zone 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 insulation material, each two-layer should set fire barrier zone ; 4, the height of building is less than 24m, the combustion performance of insulation materials should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone.
Q:Can someone professionally introduce the classifications of refractories?
It can be divided into two categories of ordinary and special refractory. Ordinary refractories can be devided into acidic, neutral and alkalinee refractories according to chemical properties. Special refractory can be devided into high temperature oxide, refractory compounds and high-temperature composite materials according to the compositions. Furthermore, it canbe devided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and super refractory products (above 2000 ℃) according to the strength of refractoriness. It can be divided into bulks (standard brick, special-shaped brick, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia and boron carbide, etc.) and Indefinite shape (refractory clay, castableand ramming mass, etc.) according to the shapes of products. According to the sintering process, it can be divided into sintered products, cast products, melting jetting products.
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:Refractory materials are needed for casting metallurgy.
Refractory material used in foundry work is that refractories for cupola furnace? Cupola is a high temperature furnace which is used for melting molten iron, and refractory material adopted is mainly low iron high grade clay brick and clay lightweight insulation bricks, etc.foundry ingot refractory material is pearl sand (also known as pearl jewelry sand, fused ceramic, ceramic sand) it is made of high quality bauxite material by arc melting furnace.
Q:What are the characteristics of thealuminium oxide refractory?
Alumina refractory are characterized by uniform granularity, mobility, good dispersity. And it has good acid and alkaline slag erosion resistance, high strength, abrasion resistance, high melting point, erosion resistance , anti-flush and excellent thermal shock resistance.
Q:How to count the construction costs of refractories?
In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.
