Q:What is the limit of fireproof rolling shutter?: Fireproof rolling shutter door is a kind of fire protection and heat insulation facility which is suitable for the large openings of buildings, having a certain effect on the design and installation. Fire shutter doors are widely used in fire partition of industrial and civil building. It can effectively prevent the spread of fire, to protect the safety of life and property. It is an indispensable modern building fire facilities. According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: 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:The performance of refractory material: The mechanical properties of refractory material include withstand voltage strength. The structure properties of the refractory materials include porosity, bulk density, such as thermal emission rate. The physical properties of the refractory materials include temperature conductivity structure performance, wear resistance, hiphotos, electrical conductivity, creep, the hydration resistance, adhesive strength.

Q:How to do environmental impact assessment for refractory Co., Ltd.: Give you a list of data, you can refer to. List of required data for environmental impact assessment 1) name, type, specification and quantity of main process equipment. 2) the supply and consumption of raw and auxiliary materials (annual consumption and unit consumption of raw materials, ingredients, electricity, new water and recycled water). 3) public utilities: power supply system: need to build several substations? What is the size of the substation? Water supply system: fresh water consumption, circulating cooling water consumption, domestic water consumption, production water consumption, fire water consumption, respectively, how much? Heating system: if the project has a self heating system, the size of heating boilers, types, scale, fuel types, sources, annual consumption, the boiler's circulating water supply.

Q:which kind of refractory is used in golden smelting furnace? How about his using temperature: generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.

Q:which kind of fire?bulkhead is better?: General business fire endurance of two products are 3 hours. Organic fire bulkhead's main ingredient is organic material, which can be used in anti-corrosion and fireproofing cable tray. Inorganic fire?bulkhead's main ingredient is inorganic material, which mianly play a role of fireproofing. It's main ingredient is inorganic material, so it can't be used in acidproof and alkali resistant projects. Of course, the price of same amount organic fire?bulkhead in general is more expensive than the inorganic fire?bulkhead.

Q:What's the fire?retardant material of roller shutter fire resistance door ?: It is composited by inorganic materials, and main componets are perlite and inorganic adhesive, etc.

Q:What is the acceptance standard of refractory?: Feeler gauge is used to check the thickness of the refractory brickwork joint. The top of the gauge can not be sharpened. Feeler gauge is of the width of 15mm, length of 100mm and thickness of 1, 1.5, 2 or 3mm. The thickness is eligible when the depth which the feeler gauge is inserted in is less than or equal to 20mm. Ten places should be inspected per 5m2 of masonry surfaces. It is qualified when the condition in which thickness of the brickwork joint is 50% larger than a predetermined depth is not less than five times and it is excellent when the condition is no more than two times.

Q:Does the external wall thermal insulation materials level b1 need the fire barrier zone?: First, the cotton fire barrier zone "rock wool board" mainly uses water-repelling rock wool board produced by pendulum method as thermal insulation layer materia, and connecting and fixing base wall by binding and nail bonding, it is composed level A non-combustible building energy efficiency thermal insulation system by plastering layer composed by plastering mortar and glass?fiber mesh and decorative mortar finishing layer or coating. Rock wool board exterior insulation system, low thermal conductivity, good ventilation, combustion performance advantages of higher levels can be used in new construction, expansion, renovation of residential buildings and public buildings energy-saving exterior wall insulation works, including exterior insulation, fire Barrier non-transparent wall insulation and EPS external thermal insulation system. The introduction of main level A fireproofing EIFS on the present market (The following text is selected from China Building Standard Design and Research Institute " external wall thermal insulation building construction" Standard No. 10J121) Second, the foam concrete fire barrier zone 1. It is very green without the release of irritant and harmful gases; no mineral cotton floats do harm to human skin and the respiratory tract; production of?toxic?gases is security level (AQ1), there is no harmful gas and waste emissions and less carbon emissions; it exist not duplicate insulation demolition waste to pollute the environment.

Q:What are Grade-A waterproof inorganic thermal insulation materials?: Grade-A waterproof inorganic thermal insulation materials include: 1. external wall thermal insulation materials: (1) silicate thermal insulation material (2) gelatine powder polyphenyl granule (3) steel wire gauze picking cement cystosepiment (Estazolam plate) (4) extruded sheet; 2. roofing materials: (1) XPS Extruded sheet (2) EPS cystosepiment (3) perlite and perlite bricks (4) vermiculite brick; 3. heating and air conditioning material: PUR, rubberplastic sponge, polystyrene foam, glass wool, rock wool; 4. steel structure material: polystyrene, extruded board, polyurethane board, glass wool roll mat, etc.

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.
