Description:

SIMAS65 is a kind of sintered spinel made of high purity alumina powder and high quality active

magnesia, sintered at super-high temperature. It has low creep rate, small thermal expansion

coefficient, the strong ability of anti-chemical corrosion.

Applications:

SIMAS65 is used for making high quality castables for ladle and for con-casting slide plates, SIMAS65 is also widely used for making blast furnace hearth, stove and ceramic kiln.

Q:The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.: Different thermal technology equipment has different operation condition and select different refractory material. We should take economical and practical as principle.

Q:How to use fire-resistant soil?: In fact, the refractory soil is not strong. Refractory soil is clinker, there is no strength, also known as "blade mud", he is used as filling materials, the use of thickness generally not more than 3mm. Therefore, the furnace insulation can not be done.Civil boiler interior insulation, you can use "high aluminum cement", also known as refractory cement on it.

Q:Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: Of course, there are also some docks that need not be fumigated! But also according to the requirements of the port of destination guests, because customs clearance may be proof of fumigation!

Q:What is the fire resistance thickness of the thin fire-retardant coatings?: Our thin steelwork fireproof coatings: the fire resistance is 2.5 hours, the thickness is 4.9 mm, the fire resistance is 2.0 hours, the thickness is 3.5 mm, the fire resistance is 1.5 hours, the thickness is 1.75 mm, the fire resistance is 1.0 hours, the thickness is 1.17 mm.

Q:which kind of refractory is used in golden smelting furnace? How about his using temperature: generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.

Q:How to count the construction costs of refractories?: In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric?acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.

Q:Who knows what kind of material the fire-proof plate use, and is it good?: It is the decorative board made by adopting silicious material or calcareous material as the main raw material, and blending them with certain proportion of fibrous material, lightweight?aggregate, adhesive and chemical?additive before steam pressing. It is a kind of new material and more and more frequently used currently not only for it is fireproof. Construction of the fire-proof plate has higher requirements on the adhesive, and the price of the fire-proof plate with better quality is more expensive than that of the decoration panel. The thickness of the fire-proof plate is generally 0.8mm, 1mm, and 1.2mm. So it is the best material for making cupboards.

Q:Which manufacturers have the best fire-proof materials with light weight?: Recommend Hubei Boyuejia Industrial Co., Ltd. It is a specialized high-tech enterprise that integrates research and development, production, sale and installation of new lightweight fireproof partition panel, partition panel, new partition panel and mechanical?equipment. Products are lightweight, fireproof, waterproof, sound insulation, thermal insulation, fracture resistance, anti-permeability, environmental protection, strong constitutive property (dense humidity) and other superior performances. It can be widely used in all types of lightweight wall panel of all kinds of buildings, and is one of the preferred materials of plant, residence, hotel, office building and public buildings.

Q:What is the the best ratio of mortar in refractory cement?: The ratio of refractory cement are: M10 the ratio of cement and mortar: cement: Sand= 346kg: 1631kg M7.5 ratio of cement and mortar: cement: Sand =274kg: 1631kg M5 The mix proportion of cement and mortar: cement: Sand = 209kg: 1631kg M10 mix proportion of composite mortar: cement: Sand: Lime =306kg: 1600kg: 29kg M7.5 mix proportion of composite mortar: cement: Sand: Lime =216kg: 1600kg: 64kg M5 The mix proportion of composite mortar: cement: Sand: Lime =205kg: 1600kg: 100kg
