- Q: What kind of insulation material can withstand 350-600 degrees of high temperature?
- Suggest that you refer to the above two data to choose from, select only from the temperature, you can use
- Q: What heat preservation material is used for thermal insulation of steam pipe in power plant? How thick is the bag? Please advise!
- Steam pipe in power plant thermal insulation rock wool board thickness, according to the temperature in the pipeline to choose, the higher the temperature insulation thickness is generally 80 to 150 mm.
- Q: Calcium silicate board white ICI belongs to wood surface paint?
- ICI can generally be considered as wall paint (latex paint), and latex paint can be used on this kind of cement board. And lumber is different, it is not suitable to brush latex paint on the surface of wood, it can only be decorated with paint (oil paint).
- Q: What are the new energy-saving building materials? What's new?
- As far as its varieties are concerned, the new wall materials mainly include bricks, blocks and slabs, such as clay hollow bricks, waste clay bricks, non clay bricks, building blocks, aerated concrete, light plates and composite boards.
- Q: What's the use of white portland cement?
- All the raw meal with the proper components up to the partial melting of the calcium silicate as the main ingredient, the iron content in clinker less addition of gypsum, white water ground made of rigid cementitious material, called white portland cement (the white cement).When grinding cement, allow limestone not to exceed 5% of the cement weight.Note: cement is allowed to be added to the grinding mill without damaging the cement properties. The amount of cement added shall not exceed 1% of the cement weight. The addition of additional substance must be tested and reported to the Ministry of construction materials for approval.
- Q: What are the main use of lime?
- Lime milk and mortar, slaked lime or lime paste, with lots of paint. Lime mortar or slaked lime powder can be used to prepare lime mortar or cement lime mixture mortar for masonry or plastering engineering.
- Q: What's the use of low carbon steel insulated nail hooks for power plants?
- Low carbon steel nail insulation (aka: insulation pins) material: low carbon steel wire for power plants or stainless steel wire products: insulation nail. Hook nail is a power plant by mechanical processing of special insulation nail models: nail diameter: 3 mm with 3.5mm with 4 mm with 5 mm with 6 mm etc.
- Q: Eterpan with calcium silicate is sold on the market are the same thing? Non asbestos calcium silicate board is Eterpan it
- The market is generally understood, but in fact, Eterpan belongs to Guangzhou eternit limited production of the 100 year history of eternit brand board, because the cement product is Belgium hetet group invention.
- Q: How to make building glue?
- A building adhesive consisting of 28-50wt% sodium silicate aqueous solution, 34-53wt% quartz sand, and 8-35wt% magnesium silicate. The product of the invention can be used for the bonding of ceramic tile, floor tile, marble, wood and glass in indoor and outdoor decoration of buildings. It can be used as a substitute for cement in the field of tiling. The product of the invention is environment-friendly products without pollution when being produced and used. The utility model has the advantages of low price, strong adhesive force and curing at normal temperature.
- Q: What is dew point of thermal insulation material?
- Insulation materials, insulation for industrial equipment and piping, thermal insulation measures and material aerogels were first applied to the space suit thermal insulation linings developed by nasa. With low thermal conductivity, small density, high flexibility, fire, waterproof and other characteristics. Its temperature coefficient of thermal conductivity 0.018W/ (K = m) and absolute waterproof, insulation performance is 3~8 times of traditional materials.
