Qaulity Control of High Aluminum Insulating Castable Refractory for High-temperature Industrial Kilns
Raw Material Selection: To ensure the quality of our raw materials, we only purchase our raw materials from our long-term trusted suppliers. With every purchase, the raw material must be passed 2 times inspecition, 1 time at our supplier’s site. a second inspection on the batch after the material arrived to our factory. Each time raw materials enter our facility, they are inspected again prior to being accepted.
Process Quality Control: Starting from the raw material into factory, Every production process of Insulating Castable Refractory should through strict quality control, In addition to rigorous process control, our quality control team inspects the output of each process to ensure material quality and consistency. We do our best to supply the products with best quality to satisfy our customers.
FACTORY:
- Q: Are fire materials poisonous after burning?
- High temperature oxide materials in refractory special applications, such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, including metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.
- Q: What problems should be paid attention to while using refractory materials under a controlled atmosphere?
- Pay attention to the performance of the materials, and the use of non oxide materials!
- Q: Can anyone tell me the requirements of the refractory masonry?？
- Refractory materials actually have two functions. The first one is to improve the refractoriness and the second one is to improve the body plasticity of refractory materials.The higher the aluminum content is, the better refractory it will be. Of course, the content of aluminum in refractory materials can not be impoved only by using kaolin. Such raw materials that contain more aluminum as bauxite chamotte should be used as framework.So the content of aluminum in kaolin does not need to be too high and more than 38% of aluminum is enough. However, the viscosity should be taken into account. It will be better if the viscosity is better as the extra bentonite do not need to be added.The refractoriness that is is above 1400 degree is enough.
- Q: What is the difference in the nature between the refractory material and thermal?insulation?material
- thermal?insulation?material is a material which has a strong impedance to the heat flow. the nature of the material requires that the material can isolate the delivery of thermal, and the low heat conductivity coefficient and expansion coefficient of the non-metal material.refractory is good in heat resisitance and chamical erosion but not high temperature resistance. Requirements on nature is still in high temperature.
- Q: What's the requirements of fire-fighting criteria of heat insulating material?
- It shouldn't be under than B2 level. Roofing insulation fire rating requirements: the ministry of public security, housing and urban-rural development department issued about printing and distributing the civil building external thermal insulation system and the interim provisions on the exterior wall decorative fireproof prescribed in the notice: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm.
- Q: what is the common materials for home fireproofing material?
- 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion
- Q: What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?
- The new external wall fireproof and thermal inuslation matertials have both the advantages and disadvantages. Advantages: 1)Low requirements on the waterproof, weather resistance and other technical indicators. The dry wall and gypsum plastering mortar, etc. can meet the requirements and can be easily obtained; 2) The inner insulation material are separated by the floor, and construct within a height of only a storey , without erecting scaffold ; 3) In the hot summer and cold winter or hot summer and warm winter area, the inner insulation meets the requirements; 4) The glass beads overcome the shortcomings of expanded perlite, like, large amount water absorption, easy powdering, big volumetric shrinkage in the slurry mixing process, easily leading to post-insulation product performance degradation and hollowing, cracking, and also make up for the defects of polystyrene particles organic materials, like, flammable, poor fire performance, producing harmful gas at high temperatures and anti-aging, poor weather resistance, poor workability and large rebound in construction, ect. Disadvantages of external wall insulation : 1) Since the ring beam, slab and column structure would cause thermal bridges, leading a greater heat loss; 2) It is of low intensity, high water absorption, easy to shrink and crack. The insulation system is prone to cracking, leaking or loss and other common quality problems, especially it is easy to crack at the seams, thus being difficult to exsit as long as the building. 3) It is inconvenient for the users to redecorate and hang ornaments; 4) It takes up indoor used space;
- Q: What kind of refractory decorative board has good quality?
- The unique design and personalized style of well-known brand "transit" rank highest in the field of domestic refractory slab. It is one of the largest manufacturers of high pressure decorating refractory slab in China. The production base covers an area of 40,000 square meters and the annual output is 4 million. It passes the test of Quality Supervision and Inspection Center of National Fire Protection Building Material and ISO9002 certification. The products pass international standards such as 4586, the United States NEMA and so on.
- Q: Development trend of refractory industry
- In the central provinces in Henan, Shanxi, Liaoning China main manufacturer of refractory material, which is the main origin of three China bauxite, magnesite and other refractory materials; refractories industry by the end of May 2009 more than 3236 enterprises; industry revenue reached 67 billion 52 million 540 thousand yuan, Henan Province, Liaoning, Shandong, Jiangsu, Hebei and other regions, and refractories industry in the development of better leading enterprises, such as blue and white, accessible, prco etc. at present, its sales in the industry in the proportion is still small, the largest sales is also inadequate in refractory industry in 4%. An enterprise should play a leading role in leading enterprises in the industry, and its turnover in the industry should be more than 15%. Obviously, at present the refractory industry in the leading enterprises do not have, and the refractory industry concentration needs to be improved, and the existing resources in the refractory industry integration, is undoubtedly the way this process effective and efficient.
- Q: What are the main materials in concrete fireproofing material?
- it can be roughly divided into: fire-resistant coating for steel structure, finishing fire retardant paint, tunnel fire coatings, concrete fire?retardant?coating, cable refractory coating. fire-resistant coating for steel structure is divided into: Indoor ultra-thin fireproof coatings for steel structure, indoor thin steel structure fireproofing coating, indoor thick steel structure fireproofing coating, outdoor ultra-thin fireproof coatings for steel structure, Outdoor thin steel structure fireproofing coating, outdoor thick steel fireproofing coating. I hope it can help you. Hope to adopt my opinion Thank you! )
