Q:Integrated ceiling and calcium silicate board which is good
Calcium silicate board ceiling in addition to not in the kitchen outside the bathroom can be ... ... High strength, small thermal conductivity, high temperature, corrosion resistance Widely used in industrial and commercial construction of ceiling ceilings and partitions Because the fear of soot is not easy to clean up ... ... so different places to use a different ceiling
Q:Calcium silicate board production line
The method of copying is to flow the prepared slurry into the cage through the slurry tank, and the slurry is submerged to about 3/4 of the diameter of the reel, and the outer ring is wrapped with a certain number of internal and external networks. The upper part of the wheel set with a roll of blankets and blankets in contact with the wheel, running, the chest roller rotation to drive the blanket running, the passive roller rotation while driving the rotation of the wheel, the slurry in the role of pressure through the reel filter, Layer attached to the net outside the net, because the net is a porous and can be through the air, and the fog roll, blanket and material layer between the more dense, no air can be passed, so the material layer more easily from the reel to the wool , Thin primary layer was continuously passed on the blanket. The stirrer is used to prevent the slurry from settling, and the heavy sand debris sinks to the bottom of the tank and is periodically removed by the release plate of the floor. The material layer through the vacuum box after dehydration, winding to the forming tube, to achieve the required thickness from the molding tube after pulling off the wet blank, the next process into a variety of products.
Q:Can silicon calcium board be used for roof insulation?
Silicon calcium board has thermal insulation properties, can be used for roof insulation
Q:What parts need calcium silicate board?
Calcium silicate board is generally used for fire, waterproof requirements of the partition, ceiling, fire duct, steel fire, curtain wall liner.
Q:Perforated calcium silicate board What is the meaning of sound absorption wall
Perforated calcium silicate board than the average calcium silicate board is different from the sound absorption in this area, of course, there are different reasons for the substrate, perforated calcium silicate board sound absorption wall is mainly because the calcium silicate board surface perforation, which has a sound-absorbing effect
Q:Calcium silicate board ceiling, wall patchwork and vertical degree how to control?
If the height of the ceiling can be used to determine the height of the tile, you can use the wood is 3cm thickness * wall length, with steel nails to fix the wood on the wall above the tile, according to the determined installation height on the wood with ink bucket Horizontal Line Installation Edge. I hope I can help you
Q:Calcium silicate board material production methods which
Secondary reaction method (also known as joint method) is the most complete hydration reaction, the most easy to get high temperature, light high strength calcium silicate products, calcium silicate board production process, but its shortcomings process long, energy consumption, investment Big.
Q:Calcium silicate board and magnesium silicate board which is better
In recent years, with the improvement of production technology, the use of calcium silicate board is also more and more common in Guangdong, in addition to the external brand of Etterit, there are Oulang, Jinfu, Chun Figure, Yin Xing and other own Brand.
Q:Office building silicon calcium board ceiling, the actual construction practices: light steel keel spacing 1000mm, small keel spacing 600mm meet the requirements
Construction Measures of Caustic Sintered Calcium Silicate Board Ceiling 1, the roof height level: according to the level of the floor level, with the vertical foot to the ceiling design elevation, along the wall to the surrounding height of the ceiling. 2, designated keel file line: according to the design requirements of the primary and secondary keel spacing arrangement, has been on the roof of the standard elevation of the keel sub-line. 3, the installation of the main keel boom, playing a good ceiling elevation and keel sub-file position, to determine the boom under the head of the elevation, according to the main keel location and hanging spacing, the end of the bucket without screw button embedded with the floor expansion Bolt connection is fixed.
Q:Is it harmful to calcium carbonate on home improvement?
Asbestos content of 100% without asbestos, HBC223-2005 "lightweight wall panels" Radioactive Class A materials, production and marketing and use of unrestricted. In line with GB6566-2001 "building materials radionuclide limit" Non-combustible Class A incombustibility, in line with GB8624 "building materials combustion performance grading method" High-performance, high strength, fire, water, moisture, noise, insulation, insulation, shock, impact resistance, anti-aging, corrosion resistance, pest control, easy processing, easy decoration, stable performance.
