Q:What kinds of refractory will be used in kiln of sintering ceramics?
High alumina brick, clay brick, insulating brick and silicon carbide plate.
Q:Which kind of refractory floor is easy to use? ?
Recommend: Yong Wei fireproof board Henan Yong Wei Anfang Co., Ltd., located in Qinbei industrial agglomeration area, Qinyang City, Henan Province, was founded in 1995. It strated from the initial one fire decorative plate production line. After years of development, it has become the biggest fireproof decorative board production base with 25 fireproof board production lines.
Q:How long is the fire endurance of Grade A fire resisting shutter
Fire door can be divided into Grade A, Grade B and Grade C fire door according to its fire endurance. Their fire endurance is not less than 1.20h, 0.90h and 0.60h respectively. Use fire resisting shutter as fire compartment separation in places where it is difficult to set firewall. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is used, its fire endurance should not be lower than 3h. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is not used, individual protection of  closed automatic water spray system shoule be set at two sides of the shutters and duration of water spray system should not be less than 3.0h. When the fire resisting shutter is used for fire compartment, fire endurance is 3h. When the fire resisting shutter is set at the opening part of firewall, fire endurance is 1.2h.
Q:What is the type of heat resistance property of high temperature electric furnace ?
According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃
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:What are the specifications of fireclay bricks?
1. The various classification criteria of clay bricks. First, according to the physical and chemical indicators, they can be divided into these types: (NZ) -42, (NZ) -40, (NZ) -38. Second, the classification of specifications of clay bricks is in line with the stipulations in "general shape and size of refractory bricks". Finally, according to the stipulations of relevant state departments, the clay bricks can be divided into standard bricks, ordinary bricks, special-shaped bricks, special bricks. Second, level of refractory temperature of refractory bricks The refractoriness of refractory bricks is divided into four levels according to changes of alumina content. We know that the components in clay bricks include Al2O3. Alkali metals are also included. The refractoriness of AAA-level clay bricks in Ruitai Refractory Material Factory is 1750 ℃; A-level bricks is 1730 ℃; B-level bricks is 1670 ℃; and C-level bricks is 1580 ℃. The softening temperature under a fixed load of Clay bricks is about 1350 ℃. Clay bricks, also known as sintered bricks, are small size artificial bricks for modern architecture. Clay bricks have good properties and high thermal stability, in which Fe2O3 content is less than 2.0 to 2.5%. Overall dimensions: 230 * 115 * 65mm
Q:What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
glass
Q:How long does it take for refractory cement to solidify?
1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.
Q:Which industry does refractory belong to? Does it belong to construction industry?
I do not recognize all the answers. No matter what kind of refractory can be used in construction. Biulding syove or kiln is construction. So personally, it belongs to construction indusrty.
Q:how about the performance of aluminum silicate fire proof thermal insulation?
aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing agent, molding by high temperature and high press. MDF(medium density fibre board) structure is more even than natural wood. it avoids rot, moth-eaten and other problems, while medium density fiber board has small expansion and contraction, which is easy to be processed. Since the surface of medium density fibre board is smooth, the board is easy to paste a variety of finishings, which makes furniture more beautiful. A variety of decorative wood-based panel is to embellish their homes.
