- Q: A chemical problem with refractory materials
- Not necessarily. What you mean is silicate
- Q: Who knows about the fire endurance of A grade fireproofing glass doors?
- Fire doors and windows are divided into grade A, B and C according to the real national situation, also the minimum fire endurance has been stipulated, namely, the minimum fire endurance of grade A is 1.50 h, that of grade B and C are 1.00 h and 0.50 h respectively. There are wooden fire doors and steel fire doors. The main purpose of it is to reach the time that fire resistance should last. But door?closers are required to install. The fire endurance of A grade wooden fire doors should be no less than 90 min, and that of B grade fire doors should be no less than 60 min, that of C grade fire doors should be no less than 30 min! ! !
- Q: Why can aluminium hydroxide not be used to make refractory material?
- Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
- Q: What are the materials of insulation firebricks?
- The furnaces of firebricks are generally divided into two types, namely, unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also called castables, is a mix of powdery particles of many aggregates and one or multiple adhesives. They must be stirred well with one or multiple liquids when in use, which has a strong liquidity. Unshaped refractory materials generally refers to firebricks. They have standard rules about their shapes and can also be processed temporarily as needed.
- Q: How to distinguish the construction fire-proof material rating?
- According to national standard GB8624-97,combustion performance of building materials are divided into the following levels: Class A: Incombustible building material: Material that almost never burn. Class B1: Nonflammable building material: Nonflammable materials have good effect of flame resistance. In case of fire it in the air or at high temperature it is difficult to catch fire and spread, and when the fire source is removed, the combustion can stop immediately. Class B2: Combustible?building?material: Combustible materials have good effect of flame resistance. In case of open fire in the air or at high temperature, it will immediately burst into flames and spread the fire quickly, such as wooden column, timber roof truss, wooden stairs, etc. Class B3: Flammable building material: No flame-retardant effect, highly flammable, high risk of fire. According to national standard, the fire?rating of PVC floor must be class B1.
- Q: How many types of special refractories are there?
- Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
- Q: What are the qualifications of refractory industry?
- 1 business license 2 tax registration certificate 3 organizing institution bar code 4 production permit
- Q: What are the specific steps of stirring the steel ladle castable?
- Steps are as follows. 1 Compulsory mixer is used to stir the castable and bags, rope and other debris can not mix in the castable when stirred. 2, Castable should be unpacked on the scene. Stirred volume depends on the capacity of the mixer. Castable should be accurately measured and put into a blender. 3 The process of first dry mixing and then wet mixing is adopted. After the castable is added to the mixer, it is dryly mixed for 2 minutes, add about 5.2 to 5.5 percent of water and continue to add water while stirring. Water that is 80% of the total should be added, and then decide whether to continue to add or not depending on the consistence (noting that the water must be clean water and sewage can not be used). Then it is wetly mixed for 4 minutes and stirred for not less than 6 minutes at one time, until castable is even. In general, the bottom is slightly dry and the wall of the ladle is slightly dilute (the amount of water is only for reference). 4, The amount of water and mixing time should be controlled strictly when stirred to ensure that the needs of the consistency are met. If castable is too thin, it will seriously affect the quality of the material. The stirred volume, stirring time and water that is added should be consistent and they can not suddenly be thick or suddenly be thin. If the consistency does not meet the requirements, the castable should be put back to the mixer and stirred with appropriate water or dry materials. 5, It should be stirred evenly and casting should finish in 20 minutes, in order to avoid sclerosis, affecting structural strength of ladle lining 6, After each completion of construction, varieties of castable should be changed and the mixer should be cleaned 7, Stirring can stop in halfway. If the mixer breaks down and it can be repaired in a short time, some of the materials have to be removed before the machine is opened. If the machine can be repaired on time, castable refractory should all be removed.
- Q: How many fire endurance grades are the AAA fire resisting shutter divided?
- According to the fire endurance, the fire doors can be divided into Class A, Class B and Class C fire doors with the fire resistances are not less than 1.20h, 0.90h and 0.60h. Even the fire resistant level of B can also use the first rate fire resistant door.
- Q: What kinds of fireproof materials does the safe use?
- The fireproof materials of the safe, cement foam. It is often said recently that the safes with cement inside are bad. Actually, it is not like this. Chemical means are taken to make the cement inside safes rise like a leaven dough so as to achieve good insulation. The principle is the cement foam. Fireproof safes with such techniques have good performance in terms of fireproofing and anti-theft. The manufacturing processes of this fireproof safe are highly technical, some safes with poor techniques have problems in quality. Here are some data of the foam cement.
