High Alumina Ceramic Rollers

Q:What is the main role of fly ash added in concrete products?: Fly ash can inhibit the bleeding of fresh concreteFly ash can fine crumbs compensation in fine aggregate shortage, interrupt continuous bleeding mortar channels, and fly ash as cement replacement materials in the same consistency will make use of concrete water quantity is reduced in different degree, thus adding fly ash is beneficial to prevent the fresh concrete the bleeding.

Q:How to make building glue?: Universal type building adhesive and preparation method thereof, which is characterized in that the main components of the building glue: TDI, polyether, polyester, multiple resin, natural plant resin, polystyrene thin ester, solvent oil and ultraviolet resistant, anti-aging agent, component ratio (by weight) of:TDI2%--7%, 3%--8%, polyester polyether 1%--6%, multi resin 6%--15%, natural plant resin 6%--15%, polyphenyl ester 14%--25%, savanna solvent oil 10%--20%, anti UV, anti ageing agent 1%--4%.

Q:Eterpan and yinte in what is the difference?: The silver plate refers to the calcium silicate board. Silver is a trademark, and calcium silicate board is the name of the product

Q:Which is better, asbestos free calcium silicate and aluminium silicate refractory fiber?: The two are thermal insulation materials. Calcium silicate board strength, cheap, but the use of temperature is not high, the highest 1000 degrees.

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 kind of insulation material can withstand 350-600 degrees of high temperature?: GB 50264-97 code for design of thermal insulation engineering for industrial equipment and pipelines98T901 cold storage Atlas of piping and equipment

Q:What are the raw materials of cement products? What's the function?: Water is necessary for the production of cement products, the role of water is to cement hydration. Generally, the water cement ratio of concrete is 0.40~0.65. If the water is too large, it will leave a hole in the concrete, which will affect the strength, density and durability of the concrete and even cause water leakage.

Q:Asbestos free calcium silicate board there is a crack in the kettle, what is the reason?: Calcium silicate slab blank (blank off off phenomenon is not forming tube adhesion fingerboard blank above)There are two reasons: one is the blank off the vacuum negative pressure is too large, the blank water is too low, low viscosity; two is felt blocked, the billet made worse.The solution is to reduce the negative pressure, strengthen the cloth washing.

Q:What is a building energy-saving materials?: Mainly include new wall materials, insulation materials, waterproof sealing materials, ceramic materials, new chemical materials, decoration materials and various industrial waste residue comprehensive utilization.
