Q: What are the standards of refractory concrete ?: Heat-resistant concrete refers to the kind of concrete which remain undamaged, do not lose the necessary bearing capacity at 200 ~ 1300 ℃ high temperature for long term, and still maintain its physical and mechanical properties.

Q: What are the qualifications of refractory industry?: Certificate for production and sale is needed, just like the certificate for other products.

Q: Which industry does refractory belong to?: It belongs to construction industry.

Q: How to do environmental impact assessment for refractory Co., Ltd.: 1, first of all, the EIA unit and the construction party signed the EIA contract. The contract is only legally valid. Generally speaking, the contract will indicate that the first payment has been received before the work begins.2. Collecting information. This is a very important link in the EIA, which is directly related to the quality of the eia. There is a great variety of data,Generally, the construction party will write a list of environmental impact assessment information.

Q: How long usually will the A-level fireproof materials prevent the flame?: The classification of A-level materials is based on GB8624 - 2006 building materials and products combustion performance of grading method. Specific technical requirements are: 1, temperature ≤30 degrees; mass loss rate ≤50%; continuous burning time is 0; 2, the gross calorific value of main components, overall products, external non-substantial components ≤2.0MJ / kg; any internal non-substantial component ≤1.4MJ / kg;

Q: What kind of materials can be tested their electrical resistivity in the current refractory industry?: Graphite, Magnesium Oxide, and alumina are all feasible.

Q: What is the fireproofing requirements of external wall thermal insulation materials?: in the 2011 and 2012 revised version of "Fireproof? Specification of Building Design" in China, the external insulating layer of above 50 meters (approximately 16 layers) of the housing must use the level A material. The latest draft for approval is not so strict, above 100 meters (about 33 layers) only use level A material. The manuscript of "Building Regulations" is also regulated building's external wall thermal insulation materials in the crowded places should be level A. Except the residential buildings and the buildings in the crowded places, the height of other buildings is greater than 50 meters, combustion performance of insulation materials should be level A; the height buildings is greater than 24 meters but not more than 50 meters, combustion performance of insulation materials should not be lower than level B1. "Building Regulations" manuscript should relax the rules on the aspect of protective coating in level B1 and B2 insulation material. The outer of level B1 and B2 level insulation material must use incombustible?material as protective coating, its thickness is changed from the original 10 cm to 5 cm. Given certain conditions, I feel you can use TDD exterior wall thermal insulation decoration integrated rock wool board for construction, which is level A fireproofing with a short construction period and good thermal insulation properties. I hope I can help you!

Q: How many levels are there in the classification of PP fireproof materials?: PP fireproof materials level V-0: After two 10-second fame tests on the sample, the flame extinguishes within 30 seconds. Inflamer can not drop. V-1: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can not drop. V-2: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can drop.

Q: Is it normal for caable fire resistant material to catch on fire?: Abnormal; aging is certainly one of the cause of the fire. That is caused only because of poor insulation and aging caused by short circuit, but a more important reason is configuration of air switch does not meet the requirements. If the capacity of air switch equals that of the cable, trip will happen at the moment when current is overloaded, not causing a short circuit or over current fire.

Q: How to divide the fire resistant level of construction thermal insulation materials?: How to divide the fire resistant level of construction thermal insulation materials: Combining three versions of GB8624 (1997,2006,2011) external wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indexes for specific division, very professional and technical, so it is hard to say clear now. For details, please contact Qingdao Shanfang Instrument Company who is specialized in fire?rating tester for external wall thermal insulation materials.
