Q: What are the fire protection standards of insulation materials?: This question is, like this. The combustion performance of thermal insulation materials for exterior walls of all civil buildings, within the scope of fire design auditing and fire control acceptance, should be brought into the auditing and acceptance. As for the "Management Regulations on Supervisions of Fire Prevention and Control for Building Projects" (Ministry of Public Order No. 106) , all civil buildings which are out of the scope of Article 13 and 14 are included in the random check. Before the release of new standard, it must be strictly implemented the Article II of the "Fire prevention Interim Provisions on civil external wall insulation system and external wall decorative" ([2009] No. 46), namely, the insulation materials of civil buildings must use materials with A-level combustion performance.

Q: How is the grading of the level A new material fire insulation material?: The standard to distinguish level A and level B is the different fireproofing coefficient. The level A is non-combustible. The level B is divided into B1, B2 and B3. B1 is flame retardant, B2 combustible and B3 flammable. The level A is commonly phenolic aldehyde, rock wool, thermal?mortar, foam ceramics, foam glass and foam concrete on the current market. Among the advantages of level A materials, the biggest one is foam concrete currently, also known as foam cement, which the Xuzhou Green Year EEB company's main produces.

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: What's the fire endurance of hollow brick?: For hollow brick wall, it should be noted that outside are 200-thick coal gangue hollow brick wall on interior wall. Besides, the fire endurance should comform to GB50067-97 Fireproof code for garage, repair garage, parking lot design. 3), All joints of brick walls and concrete wall column should reserve rebar tie. Masonry mortar in internal and external walls should be full. Wall masonry should be up to bottom of beam slab and filled tightly with 1:3 cement mortar.

Q: What are the fire resistance ratings of the glass partition?: The glass partition system is composed entirely of metal structures, glass, color plate and other materials which also has fire resistance capacity. When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer. The fireproof glass is a special glass which is able to maintain its integrity and insulation in a fire resistance test. According to fire resistance performance, it can be divided into three categories: Class A: The fireproof glass which meets demands of fire integrity and fire insulation at the same time. This glass has advantages of excellent transmittance, fire-proofing(smoke resistance, fire insulation, and blocking heat radiation), sound insulation and impact resistance. It can be applied to architectural ornaments, fire resistant timber doorsets with steel structure, windows, upper beam, partition walls, daylighting roofs, ceiling screens, perspective floor and other building components which need transparency and fireproofing. 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. 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.

Q: How long is the fire-resistant time of fireproof wooden door?: fire endurance class A (1.5 hours), class B (1.0 hours), class C (0.5 hours).

Q: Classification of porosities in refractories and their effects on properties: Effect of apparent porosity on properties:The porosity is high, the volume density is low, the structure become more loose, generally low strength, corrosion resistance worse (slag infiltration and erosion along the hole toward the inside), but to improve the thermal shock resistance (resistance to thermal shock and not damaged).

Q: How do refractory materials apply into pyrophyllite?: Generally speaking, shaped refractory materials require of some powdery materials like spray grouts and iron trough in addition to pyrophyllite brick made of a mixture of pyrophyllite aggregate and powers.
