General Information of Ceramic Foam Filters

Alumina ceramic foam filters are widely used in filtering the alumina and alloys in foundries. With 80-90% porosity, the filters can effectively remove the alumina dross to improve the casting quality.

FAQ

Q1: How do you control the products quality?

A1: With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements. From the raw materials selecting, our quality control begin. The quality certificates of raw materials are required and each batch will be tested before using. During production, the quality control is conducted by workers and then each piece will be sorted and examined by quality supervisors.

 

Q2: What`s the lead time for my order?

A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks, 10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.

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:Cement is not silicate products
Usually refers to silicate products with lime (calcium containing materials) and sand, fly ash, slag (siliceous materials), then add a small amount of gypsum, the steam steam curing or steam curing, building products quickly generate Tobey mullite, calcium silicate, hydrated calcium aluminate sulfate and hydrated calcium aluminate such as cementitious materials and production. Such as: autoclaved fly ash (sand), autoclaved aerated concrete, autoclaved fly ash brick, autoclaved sand lime bricks.
Q:Which is better, asbestos free calcium silicate and aluminium silicate refractory fiber?
Aluminum silicate fiber can be divided into many kinds according to the aluminum content, the use temperature range is relatively large, the heat insulation property is good, but the price is more expensive.
Q:What is the main role of fly ash added in concrete products?
The later strength of concrete can be improved by adding fly ashThe experimental data show that when the concrete is mixed with fly ash, the early strength (28 days ago) decreases with the increase of fly ash content, while the latter strength increases gradually. Fly ash has three effects on the strength of concrete: reducing water consumption, increasing cement content and increasing strength through long-term volcanic ash reactions.
Q:What are the exterior walls of the building besides the benzene board and the extruded board?
Foam heat insulation material mainly includes two categories, polymer foam type insulation material and foam asbestos insulation material. Polymer foam thermal insulation material has the advantages of small absorption rate, stable heat preservation effect, low thermal conductivity, no dust flying in construction, easy construction, etc., and it is in the period of popularization and application.
Q:What's the difference between white carbon and carbon black?
There are two kinds of substances. Some aspects can be substitutedCarbon black is the hydrocarbon gas in the process of strict control of incomplete combustion or pyrolysis of a black powder.
Q:What are the new energy-saving building materials? What's new?
Mainly include new wall materials, insulation materials, waterproof sealing materials, ceramic materials, new chemical materials, decoration materials and various industrial waste residue comprehensive utilization.
Q:What are the high temperature resistant insulation materials at 400?
According to the general rules of equipment and piping insulation, heat insulation material is a material with a thermal conductivity of less than 0.14W/ (m*K) when the average temperature is equal to or less than 623K (350 degrees Celsius). Heat insulation material is usually light, porous, porous, small thermal conductivity characteristics. Generally used to prevent heat loss of equipment and pipes, or frozen (also known as general cold) and low temperature (also known as cryogenic) use, so in our country, insulation materials, also known as insulation or cold preservation materials. At the same time, because of the porous and fibrous structure of thermal insulation material, it has good sound absorption function, so it is also widely used in the construction industry.
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's the difference between white cement and ordinary cement?
The typical feature of white cement is high whiteness, with bright color, generally used for a variety of architectural decoration materials, painting, sculpture, a typical floor, terrazzo, white cement can be used to produce white and colored concrete, is the largest cement production decoration.
