Q:What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
It usually used to test lightweight refractory. Density can be divided into apparent density (usually called as density) and true density: apparent density includes blow hole inside the sample; Unit weight is using quality to divide volume of sample and specific weight is used to represent liquid.
Q:How many kilns using refractories are needed? What are the furnaces respectively?
There are many magnesia-chrome bricks and alkali insulation tiles); aluminum manufacturer roaster; The bottom of the glassworks regenerative chamber generally use the clay checker bricks, which is popularly used in many places of the steel mill. the upper of the power plant uses low pore brick and magnesia bricks. The forehearth uses the corundum bricks, and the cement plant uses dry and wet rotary kiln (silmo brick
Q:What are the fire resistance ratings of the glass partition?
When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer. The partitions in the usual sense are walls that have a distance to the ceiling. The fixed partitions directly touches the ceiling are partition walls which should be required in accordance to the specifications of walls. If the partition is far from the ceiling, the fire protection requirements are relatively low. Partitions which combustion performances are no less than B1 level are safe enough, while partitions of places such as shopping malls have to reach A-level in terms of combustion performance.
Q:Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?
(1) the height of buildings is greater than or equal to 24 m, the combustion performance of thermal insulation material should be A-level. (2) the height of buildings is less than 24 m, the combustion performance of thermal insulation materials should be A- or B1-level. When using B1-level thermal insulation materials, fire barrier zone should be set in each floor. (3) incombustible materials should be used as the protective layer of thermal insulation materials. Thermal insulation materials should be completely covered by protective coatings. The thickness of protective layer should be no less than 3 mm. (4) The base walls should be set in buildings with nontransparent curtain wall structures of metal, stone,etc. The fire endurance of which should comply with relevant provisions of current fire safety rules on fire endurance of external wall. The fire endurance and fire protection construction of pier between two windows, window sill walls, skirt walls of glass curtain walls should comply with relevant provisions of current fire safety rules on building curtain walls. (5) the internal cavity of base walls, as well as the space between the skirt wall and base walls, pier between two windows, window sill walls should be sealed with fire-proof sealing materials at each floor.
Q:What are included in wall fireproofing material?
Wall fireproofing materials include dry wall and gypsum block. Dry wall is made into board material through process by using building plaster as main material, adding an appropriate amount of additive and fiber to make board core and using tailor-made board paper as protection surface. Dry wall ia characterized by light weight, sound insulation, heat insulation, strong processing performance and easy construction method. Gupsum block is lightweight building plaster product made by using building plaster as main raw material, adding water, stirring, moulding by casting and drying. Fiber reinforced material or lightweight aggregate are allowed to add during the production and foaming agent can also be added. It is soundproof, fireproof, convenient to construct and many other advantages. It is a kind of new wall material with low carbon, environmental protection, health and in line with the development requirements of the times.
Q:Preparation of refractory clay
Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.
Q:which kind of material is chosen for fireproofing window?
(1) the inside filler material of steel, wood frame should use incombustible material. (2) window frame uses steel frame or wooden frame with certain strength that can safeguard the integrity and stability of the components. (3) steel frame and mound layer can choose galvanized steel sheet or stainless steel plate. Its selection criteria conform to the article 5.1 in GB12955 Steel Fireproof Door General Technical Condition. (4) the selection criteria of wooden frame and mound layer should conform to the article 5.1 in GB12955 Wooden Fireproof Door General Technical Condition. (5) fire-resistant glass can choose test approved products without affecting the fire resistance of fireproofing windows . Light transmittance of glass should not be less than 75% of same layers commom sheet glass. (6) the sealing material between the frame and the fire-resistant glass should use flame retardant materials, it can play a role of fireproofing and smoke insulation in the fire. (7) hardware accessories should be tested qualified approved supporting product.
Q:How to distinguish the fire resistant level of construction materials?
Division of fire resistant level of building material: 1, It can be divided into five levels according to the importance: a, special class: commerative, historic, international and national buildings. b, Class A: high-grade residential architecture and public building. c, class B: middle-grade residential architecture and public building. d, class C: orinary residential architecture and public building. 2, It can be divided into four grades according to fireproof performance: Fire resistance level buildings is divided into four levels. Standard of fire resistant level is based on the combustion performance and fire endurance of main components of the house. 3, It can be divided into 4 levels according to durable life: a, A grade durable life, over 100 years, for important buildings and high-rise buildings. b, second level durable life, from 50 to 100 years, for ordinary buildings. c, third level durable life, from 25 to 50 years, for secondary buildings. D, fourth level durable life, less than15 years , for temporary buildings. I hope my answers will help you.
Q:what's the detailed address of fireproof and thermal inuslation matertial market?
Detailed address of fire insulation materials market is as follows: A: Guangzhou Huatai building materials co., LTD. Address: Guangzhou Tianhe Chepo Road no. 10 B: Address of Donglong building materials market: Guangzhou Tianhe Taian North Road no. 7 C: Address of Huiya building materials trade market : Guangzhou Tianhe Sports West Road No. 109
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.
