- Q:who knows the fire resistant level of fireproof gypsum board ?
- combustion performance of building decoration materials should be divided into four levels: A level, non-flammable; Class B1, flame retardant; B2 level, flammability; B3 level, flammable. Choose the materials above B1level. Thank you
- Q:Who knows about the fire endurance of sintered shaly hollow bricks?
- 1. after roasting at high temperature of more than 1200 degrees, shale burned bricks in construction works can be free from expanding with heat and contracting with cold. 2. masonry walls can be plastered with no needs of any anti-cracking, reinforcement measures, and walls will not bulge and crack, which can reduce the construction cost, as well as are preferred building materials of frame structural engineering. 3.They have good sound insulation and thermal insulation performances, are one of the green building materials that the state currently promotes. 4. They have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance.
- Q:Who knows about the fire endurance of A grade fireproofing glass doors?
- The fire endurance of A grade fireproofing glass doors should be no less than 3 hours. A grade fireproofing glass doors use common glass of 6 mm. The shock resistance of float glass is about less than 5 min, and that of toughened glass is about 15 to 30 min. Fireproofing glass is classified in accordance with fire rating, the fire endurance of which is usually from 30 to120min, and that of the most common fireproofing glass is 60 to 90min, but now the market is a mixed bag, the so-called fireproofing glass is generally fake ultra-strong tempered glass. Therefore, you should buy the genuine glass with formal certificates, or you will bring yourself great inconvenience, and even more serious consequences.
- Q:Who knows how to divide the building fire grade and fire resistance grade?
- I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on. The judgment condition of the fire resistance There are three conditions for components' fire resistance limit to be reached, namely, the fire resistance limit of the building component: Loss of support and integrity; loss of time to fire the role of the time; as long as any of these three conditions is met, it will reach its limit of fire. Hope my answer will help you.
- Q:Who knows the fire resistant level of the rock wool color plate?
- The rock wool color steel rock wool board is used in a area of high ??fire safety requirements. According to "interior decoration of buildings for fire protection design", the color steel rock wool board belongd to level A. Its life is more than 15 years and still can be used when the temperature is up to about 700 ℃, with maximum fireproofing hour of six hours. And the rock wool color plate is a environmentally friendly material, the preferred material in the construction industry .
- 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:What substitutes are available for high-end refractories in addition to zircon sand?
- Natural ore, synthetic raw materials such as industrial synthetic mullite, etc..
- Q:How can refractory materials be divided?
- There are many criteria for the classification of refractories.Just referring to a book about refractory.
