- Q: Does the external wall thermal insulation materials level b1 need the fire barrier zone?
- Residential buildings should meet the following requirements: 1, The height of building is greater than or equal to 100m, the combustion performance of thermal insulation material should be level A. 2, The height of building is greater than or equal to 60m but less than 100m, the combustion performance of thermal insulation material should not be less than the level B2. When using the level B2 thermal insulation material, each layer should set a 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 thermal insulation material, each two-layer should set a horizontal fire barrier zone. 4, The height of building is less than 24m, the combustion performance of thermal insulation material 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. According to this understanding, it can not be set.
- Q: What's the refractory material?
- According to the product shape, it can be divided into two kinds, that is shaped refractory and unshaped refractory. According to the chemical?property, it can be classified into three categories, that is acid refractory, neutral refractory and basic refractory, among which basic refractory and neutral refractory are commonly used, such as the basic refractory of magnesia carbon brick, fired magnesite brick, magnesite-chrome brick, magnesia-calcium brick, and the neutral refractory of high alumina brick, corundum brick, clay brick. Unshaped refractory includes: castable, ramming mass, gunning mix, coating material, dry vibration material, etc.!
- Q: How many refractories are there for boiler above 1200 ℃？
- Ordinary clay brick is for burning layer, red brick for external wall, light clay brick for thermal insulation layer, built by clay refractory mortar. Sindeyuan Refractories.Hope you adopt. Thank you. In fact, there are many manufacturers producing furnace burden. We has been using products of Huaheng, which are anti-erosion, easy to construct and can improve production efficiency, reduce steelmaking cost.
- Q: What is shapeless refractory with high performance?
- The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.
- Q: how to classify the fireproofing material levels A1 A2 B1?
- their classification is shown specifically in Fireproof? Specification of Building Interior Decoration?Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into
- Q: What are the requirements on fire resistance period of C-level fireproof glass?
- Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance.
- Q: What is the limit of fireproof rolling shutter?
- According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: According to provision 14102-2005 GB: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.
- Q: I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?
- Metallurgical industry downturn. There is fierce competition in the refractory industry.
