  • LUYANGWOOL Ceramic fiber rope is produced by processing refractory ceramic fiber. Various textiles can be produced by ceramic fiber. LUYANG ceramic fiber ropes are woven or braided from yarn consisting of refractory ceramic fiber with approx 20% organic fibre. Alloy wire inserts are available for obtaining maximum strength ar elevated temperatures. Glas filament inserts are used in applications where electrical resistance is required. LUYANGWOOL ceramic fiber rope can be used up to 1260C.

Q:As for fireproofing material rock wool and glass wool, which one is better?
As for fireproofing effect, the effect of rock wool is certainly better than glass wool , the highest temperature of rock wool is 1100 ℃, but the temperature of glass wool is only 600 ℃. In addition, if it's used in the external walls, then,unit weight of the glass wool is limited,and high unit weight can only be 60-90, but unit weight of rock wool can reach over 140, now external wall can't use glass wool, and only rock wool is A class fireproofing material. glass wool has lower thermal conductivity, rock wool has longer fiber length,as for the price, tons price of glass wool is more expensive than rock wool, but if it's acculated by square, square price of glass wool is cheaper than rock wool.
Q:Does the aluminum silicate fiber can be used outdoors? If not, what other refractories can be used outdoors?
Q:What is the material of fire resistant glass reinforced plastics grating?
What is the material of fire resistant glass reinforced plastics grating?
Q:Fire rating of decoration materials
All light steel keel gypsum board is considered level A; if the wood finishes up to B2 grade fire rating depends on the proportion of the use of wood veneer and the proportion of this wood veneer fire grade, if the proportion of wood veneer is small,it can be considered level A
Q:How long is the duration of fire resistance of autoclaved flyash-lime bricks?
The compressive strength of the autoclaved flyash-lime bricks is generally higher, which can reach 20MPa or 15MPa, at least 10MPa, and it can withstand the 15 freeze-thaw cycles. Besides,fly ash brick is a kind of potential active hydraulic material. In the humid environment, it can continue to produce hydration reaction and make the internal structure of the brick is more dense, which is conducive to improvement of the strength. It is found in experiments and many investigations that sample some carbide which is used for foundation, plinth and drains, after one or twenty years of freezing thawing and wetting drying, some bricks have been completely carbonized, but strength is not reduced, increased instead. This is one of the merit of autoclaved flyash-lime bricks.
Q:What is the fire resistance thickness of the thin fire-retardant coatings?
There is no detailed requirement on the thickness of the thin steelwork fireproof coatings in the "Code for application technology of steelwork fireproof coating", and the thickness there refers to a certain thickness which must(at least) have fire resistance for a certain time. The thickness of fireproof coatings in engineering generally depends on the manufacturer's test reports. Our thin steelwork fireproof coatings: the fire resistance is 2.5 hours, the thickness is 4.9 mm, the fire resistance is 2.0 hours, the thickness is 3.5 mm, the fire resistance is 1.5 hours, the thickness is 1.75 mm, the fire resistance is 1.0 hours, the thickness is 1.17 mm.
Q:Who knows what kind of material the fire-proof plate use, and is it good?
Personally speaking, fireproof clapboard is very good. It is also known as fire-proof plate or fire retardant board. Made by the pressing of a variety of incombustible materials after scientific deployment, it is good in fire retardation and can be fire resistant for over 3 hours. It is also non-toxic and non-detonating with high mechanical strength, water and oil resistance, and good chemical corrosion resistance.
Q:Who can introduce the external wall thermal insulation materials fire rating regulations?
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:How to classify fire resistance rating of brick-concrete structure?
In order to ensure the safety of the building, the fire protection measures must be taken to make it have a certain degree of fire resistance, even if there is a fire, it will not cause too much damage. According to the national conditions of our country, and in the light of other countries standards, < high-rise civil building fire protection design specification > defines fireproof rank of high-rise civil buildings into level one and two; < code for fire protection design of buildings > divides the rank into level one, two, three, four, level one is the highest level, level four is the lowest. Besides that the minimum fire resistance of the building component is specified, buildings of fire resistance rating also specified requirements for combustion performance. Because the component with the same fire resistance limit is different, it is different in the fire.According to our country national standard < building design fire protection code >, the fire resistance rating of the building is divided into four levels. The fire resistance of a building is determined by the combustion performance and fire resistance of building components (such as beams, columns, floors, walls, etc.). Generally speaking, the fire resistance building of level one is a mixed structure of reinforced concrete structure or a mixture of brick wall and steel concrete structure; the fire resistance building of level two is a mixed structure of steel truss structure, reinforced concrete column and brick wall; the fire resistance building of level three is brick-wood structure made of wood roof and brick wall; the fire resistance building of level four is combustible structure which is composed of wood roof and non-combustible wall.
Q:What is the role of adding chromium oxide green in unshaped refractory materials
Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.
