Q:What are the requirements on fire resistance period of C-level fireproof glass?
What are the requirements on fire resistance period of Class C fireproof glass? The fireproof glass is a special glass which can maintain its integrity and insulation in required fire resistance tests, it can be classified into three types: Class A the fireproof glass which meet demands of fire integrity, and fire insulation at the same time. This glass has advantages of excellent transmittance, fire-proofing(smoke resistance, fire insulation, and blocking heat radiation), sound insulation and impact resistance. It can be applied to architectural ornaments, fire resistant timber doorsets with steel structure, windows, upper beam, partition walls, daylighting roofs, ceiling screens, perspective floor and other building components which need transparency and fireproofing. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance. Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure.
Q:Is there vermiculite in refractory?
Foreign horticultural vermiculite includes four levels according to the diameter: 3 8mm is No. 1; 2 3mm No. 2, the most commonly used; 1 2mm to No. 3; 0.75 1mm to No. 4, suitable for seed germination. Vermiculite has strong water absorption capacity,
Q:Current development status of qualitative refractory materials.
Q:what are the requirements of fireproofing material?
answer: 1 fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof panel, fire door, fireproofing glass, fire retardant coating, fireproof bag,etc. 2, fireproof panel is the most common texture in the market. There are two common types: One is the high pressure decorating refractory slab, it's advantages are fireproofing,moisture-proof, wear-resistant, oil resistant, easy to clean, and it has various colors; another one is glass magnesium fireproof board, external layer is decoration materials, and inner layer is mineral magnesium fireproofing material, and it can endure 1500 degrees high temperature but has bad decoration. Installing fireproof suspended ceiling in outlet channel of construction, stairwell and corridor can ensure safe evacuation of people and protect people from attacking of fire spreading in the disaster. 3, the production process of fire and moth proof wood: firstly, put general wooden materials into solution with calcium, aluminum and other cations, then soak it into solution with phosphate radical, silicate and other anions. Thus, the two ions will be carried out chemical reaction in the wood, forming a ceramic-like material, and intimately fill the voids of cells, so that the wood has the fireproofing and mothproof properties.
Q:How many kilns using refractories are needed? What are the furnaces respectively?
There are many magnesia-chrome bricks and alkali insulation tiles); aluminum manufacturer roaster; The bottom of the glassworks regenerative chamber generally use the clay checker bricks, which is popularly used in many places of the steel mill. the upper of the power plant uses low pore brick and magnesia bricks. The forehearth uses the corundum bricks, and the cement plant uses dry and wet rotary kiln (silmo brick
Q:What are the types of advanced refractory?
Divided into ordinary and special refractory two categories. Common refractories by chemical properties into acidic, neutral and alkaline. Special refractory are divided by the high temperature oxide, refractory compounds and high-temperature composite materials by its compositions. according to refractoriness it can be divided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and premium refractory products (2000 ℃ above). The article can be divided into blocks (standard bricks, shaped bricks, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminosilicate, zirconia and boron carbide quality, etc.) and irregular shape (refractory clay, pouring materials and ramming mixes, etc.) According to the sintering process is divided into sintered products, cast products, melt blown products. The appearance is shaped or amorphous according to pH it can be divided into acidic, neutral and alkalinity according to basic operation mode, there are castable refractory ramming spraying materials, impressionable plastic material, coating. according to different components, there are clay, high alumina, corundum, spinel, magnesia, magnesium, calcium, magnesium aluminum quality,magnesia-chrome, silicon, etc.
Q:How to make use of waste refractory materials whose main elements are alumina and mullite?
Crushing and pressing refractory bricks, or refractory parts . Such as welding positioner tracks use disposable tools.
Q:What are the application of old refractory bricks?
It can still be used as refractory bricks or refractory. The quality of auxiliary material is not as good as bauxite.
Q:Is there a worker in (Jigang refractory plant)?
Units in this way, it is necessary to slowly boil it, wages will come up. You are a labor worker, and can not share with the stock system staff. There's a difference between salary and vacation.
Q:What a blast furnace refractories generally?
Usually metal anchorage plus wear-resistant refractory spray paint. at the middle part we use high alumina bricks, corundum bricks. high duty refractory is important in improving bosh furnace lining.
