- Q:What are the differences between thermal?insulation?material and refractory?
- Just as its name implies, Thermal insulation means that it doesn't conduct heat instead it insulates heat inside, while refractory means resistance to high temperature and it will not be out of shape or damaged due to high temperature.
- Q:Which basic refractory is better?
- The following companies are good: 1, Xuzhou Reka Casting Material Co., Ltd. Address: No.22-2 Luoshan Road, Economic and Technological Development Zone, Xuzhou, Jiangsu. 2, Golden Triangle Refractory Plant, Xinmi, Henan. Address: Ganzhou Street, Litang Village, Xinmi City, Henan. 3, Zibo Sun Refractories Co., Ltd. Address: Wujia Village, Shangjia Town, Zichuan(Wenchang Lake) District, Zibo City, Shangdong.
- Q:I would like to know if there is any requirement for refractories in the crucible type high-frequency smelting furnace Worry！ I hope you can help me! This time!
- Stable chemical properties. The crucible material should not be hydrolyzed at low temperature. It is difficult to be decomposed and reduced at high temperature and is not susceptible to corrosion by molten slag and molten metal;
- Q:Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?
- (1) the height of buildings is greater than or equal to 24 m, the combustion performance of thermal insulation material should be A-level. (2) the height of buildings is less than 24 m, the combustion performance of thermal insulation materials should be A- or B1-level. When using B1-level thermal insulation materials, fire barrier zone should be set in each floor. (3) incombustible materials should be used as the protective layer of thermal insulation materials. Thermal insulation materials should be completely covered by protective coatings. The thickness of protective layer should be no less than 3 mm. (4) The base walls should be set in buildings with nontransparent curtain wall structures of metal, stone,etc. The fire endurance of which should comply with relevant provisions of current fire?safety?rules on fire endurance of external wall. The fire endurance and fire protection construction of pier?between?two?windows, window sill walls, skirt walls of glass?curtain?walls should comply with relevant provisions of current fire?safety?rules on building curtain walls. (5) the internal cavity of base walls, as well as the space between the skirt wall and base walls, pier?between?two?windows, window sill walls should be sealed with fire-proof sealing materials at each floor.
- 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:What is the material composition of the new fire-resistant coating?
- The basic composition of thick coating steel structure fire is: Binder (Portland cement, magnesium oxychloride or inorganic high-temperature bonding agent), aggregate (expanded vermiculite, perlite, aluminum silicate fiber, mineral wool, rock wool, etc.), chemical additives (modifiers , hardening agent, waterproofing agent) and water. Fireproof coating binders Portland cement, magnesium oxychloride cement and an inorganic binder of the fire-resistant coating for steel structure base material. The conventional inorganic binder include alkali metal silicates and phosphates substances.
- Q:Is there a worker in (Jigang refractory plant)?
- Ha ha, base should be rest, you won't give you money, Hugh or those money, endlessly is your dedication. Should be double cease, ah, how do you say four days?. In theory, it's five days off now, and the three day of that is from the chairman to every employee.
- Q:What needs to be paid attention to in the construction of high- temperature refractory mortar?
- In the construction of high-temperature refractory mortar, the following matters should be noted: 1. Take out the organic fire blocking material and knead it into tha shape of a ball. If the temperature is too low, the blocking material along with the package can be put into 40-70℃ warm water and heated before any other operation. 2. During the use of high-temperature daub masonry stove, the minimum mortar joint should be 0.5mm and general mortar joint should be 3-5mm, which can solve the processing and fine grinding of refractory brick on the brick grinder. Besides, it is conducive to the health of workers, and can reduce the masonry effort, ensure the quality and speed up the construction progress. 3. When making urgent repair on the stove, if the joint is much too large, 2-3mm refractory pieces can be appropriately added into the high- temperature refractory mortar, and stirred to fill the joint so as to shorten the repair time and ensure normal production. 4. High- temperature refractory mortar can be painted inside various furnace body, and it should be guaranteed that the surface of the furnace body has no dust or debris before painting. The holes should be cleaned up before plugging. Lay, embed, and fill the blocking material into the gap of holes evenly. For larger holes, flame screen can be used as the framework to increase strength.
- Q:what needs to be noted when choosing and using blast furnace fireproof materials?
- it depends on the size of the blast furnace. below 200 cubic meters alumina bricks and carbon brickcan be used. 200 cubic meters and above are currently integrated bottom, not the same as the size of the cubic level, varying in the use of refactory. I hope my answers above are helpful to you and your ideal anwers.
- Q:Who knows about the fire endurance of sintered shaly hollow bricks?
- 1. after roasting at high temperature of more than 1200 degrees, shale burned bricks in construction works can be free from expanding with heat and contracting with cold. 2. masonry walls can be plastered with no needs of any anti-cracking, reinforcement measures, and walls will not bulge and crack, which can reduce the construction cost, as well as are preferred building materials of frame structural engineering. 3.They have good sound insulation and thermal insulation performances, are one of the green building materials that the state currently promotes. 4. They have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance.
