If you’ve any enquiries, please don’t hesitate to let us know.
- Q:What characteristics do A grade external wall fireproofing material have?
- 1. Save space and reduce costs; 2. Fireproofing, green and environmental protection; 3. Waterproofing; 4. Sound insulation; 5. Thermal insulation; 6. Install easily and shorten the construction period; 7. High safety performance.
- Q:whether the aluminum silicate thermal insulation material is fireproof or not?
- Yes, it is fireproof. Refractory thermal insulation material mainly refers to the inorganic thermal insulation materials and composite thermal insulation materials. According to the shape it can be divided into: Fibrous finishing, mineral?cotton, rock wool, glass wool, aluminum?silicate?wool, ceramic fiber,ect.. it takes the flint clay clinker as raw material, produced by the fusion of resistance or electric arc furnace and the injection of fiber forming. characteristic: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.
- Q:What are the raw materials of refractory?
- Refractory is mainly resistant to high temperature and fire. Sic refractories are widely used in refractory. I hope my answer will be helpful to you.
- Q:what is the grading standards of external wall thermal insulation materials?
- external wall thermal insulation materials are divided according to Fire rating: 1, the combustion performance of insulation materials rates A. inorganic fiber spray coating, glass wool, foam glass, foamed ceramic , rock wool, foam cement, obturator perlite 2, the combustion performance of insulation materials rates B1: Extruded polystyrene board (XPS)after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polyphenyl granule.3, combustion performance of insulation material rates B2. Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
- Q:which is better as household fireproof material ?
- If it is from the perspective of fire rating inorganic active insulation material for wall thermal, cement foam insulation board, glass beads of insulation movitrified?micro bead?thermal insulation?mortar, rock wool board, glass wool board, ect.. thermal insulation material are Class A fireproofing, polyphenyl board, extruded sheet, phenolic foam board, Polyurethane board, ect..belong to B1 level fireproofing, if it is used for external wall thermal insulation in decorative board, then rock wool board is more often used.
- Q:How long is the fire-fighting time of A class fire resisting window?
- Fire resisting window' duration of fire resistance: A class window, fire insulation ≥1.50h and fire resistance integrity ≥1.50h. Fire resisting window can be divided into three kinds: 一. window frame and sash framework adopt fire resisting window with steel manufacture ; 二. window frame and sash framework adopt fire resisting window with wooden manufacture; 三. window frame adopt steel and sash adopt wooden material or window frame adopt wooden material and sash framework adopt fire resisting window with steel material.
- Q:How many refractories are there for boiler above 1200 ℃？
- Ordinary clay brick is for burning layer, red brick for external wall, light clay brick for thermal insulation layer, built by clay refractory mortar. Sindeyuan Refractories.Hope you adopt. Thank you. In fact, there are many manufacturers producing furnace burden. We has been using products of Huaheng, which are anti-erosion, easy to construct and can improve production efficiency, reduce steelmaking cost.
- Q:Selection of refractory materials?
- Inorganic non-metallic material with a refractoriness of more than 1580 degrees. Refractoriness refers to the temperature of a sample of a refractory cone, which is resistant to high temperature without softening, and does not soften and melt down. Refractory materials are associated with high temperature technology, which originated roughly from the middle of the bronze age. In the Eastern Han Dynasty has made China kiln firing porcelain material and with fireclay refractory sagger. In the early twentieth Century, refractory materials were developed towards high purity, high density and ultra high temperature products. At the same time, unshaped refractory materials and refractory fibers without firing and energy consumption were developed. With the development of modern technology, atomic energy, space technology, new energy technology, refractory material having high temperature resistance and corrosion resistance, thermal shock resistance, erosion resistance and other comprehensive excellent performance has been applied.
- Q:How many types do refractory bricks have? Where the quality of refractory material is best? What is the model?
- Sinosteel Luoyang (Luoyang Refractory Material Plant in the past): High alumina(mainly blast furnace), Gongyi. There are also a series of high-tech materials (silicon carbide, carborundum, etc.) a major producer of high alumina; silicious: Resistant material for steel, glass furnace, cement kiln); magnesia. Divide from uses and divide from chemical texture; silicious(glass furnace): Xinmi, Hennan Province, Lengshui River, coke oven, etc.). As for the models, Yixing and Changxing in Jiangsu Province: Haicheng, Liaoning Province; silicious, I do not understand your intentions; magnesia (nonferrous, steel refining; magnesia: High alumina brick; Dashiqiao area! Please put it in detail.
