- 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: who knows the fire resistant levels of fireproofing glass?
- Fireproofing glass is a kind of special glass which can keep its integrity and thermal insulation performance in regular insulating refractory trials. and it can be divided into three classes according to its fire resistance: Class A, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting?roof,ceiling?screen,perspective floor and other construction components demading for transparency and fireproofing. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements. Classify from the structure,fireproofing glass can be divided into composite fireproofing glass and monolithic fireproofing glass.
- Q: Refractory material, refractory brick
- Refractory materials of various varieties, different uses, it is necessary to scientifically classify refractory materials, so as to facilitate scientific research, rational selection and management. There are many classification methods for refractory materials, among which chemical properties classification method, chemical mineral classification method, production technology classification method, material form classification method and so on are included.
- Q: What are the basic requirements of continuous casting for molten steel? What are the requirements for refractory materials?
- Refractories for continuous casting is an important part of the continuous casting machine, in addition to the characteristics of general refractory material, also for the purification of molten steel and improve the steel quality, stable molten steel temperature and composition, control and regulate the flow of the molten steel and other functions, so it is called functional refractories. The above is provided by the China Technology Department
- Q: How to hang the suspended brick in the refractory masonry?
- First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.
- Q: I am a manufacturer of refractory materials. I would like to receive some orders from abroad. I would like to know what foreign trade companies in Dalian place foreign orders abroad
- You don't give a cent to this question, no one will answer it
- Q: What kind of refractories do the anode baking furnace use?
- Usually the clay refractory bricks will be able to meet the requirements
- Q: What are the types of refractory sealant?
- Intumescent fireproof sealant: It has a characteristic of volume expansion when heated in the fire. Elastic fireproof sealant: Fire-resisting sealant with a certain to scalability (displacement capability) . Applications: Intumescent fireproof sealant is mainly used for sealing of single or small size bunches of cables through holes and filling of the gaps between the cables. Elastic fire resisting sealant is mainly used for fireproofing and sealing of construction joints (such as curtain wall gap).
