Q: What is unshaped refractory?: Castable. Castable refractory material factory to provide raw materials and ingredients, field processing, vibrator for compacting, maintenance must be after heat treatment, due to site conditions quality is not stable, but the integrity of the castable in concrete, two aspects of concrete as water and heat castable quality, raw materials the consumption ratio of concrete is 5% ~ 8%.

Q: How long is the fire endurance of Grade A fire resisting shutter: Based on national standards GB 14102-2005 specifications. It is specified in GB 14102-2005 provides that: The fire resisting shutter whose fire endurance is not less than 3h is AAA fire resisting shutter when the unexposed surface temperature rise is used as judging condition. Therefore, it is required that the fire endurance of Grade A fire resisting shutter is 3h.

Q: What is the function of refractory in ceramics?: Refractory is used as materials of kiln,sagger and kiln car for ceramic sintering. Its refractoriness is higher than ceramics, and the essential material and tool for ceramic sintering.

Q: who knows the requirements of refractory for forge furnace?: Forging heating furnace working temperatures above 1000 ° C, reasonably choosing refractory for build furnace has an important meaning for guaranteeing the normal operation of the heating furnace, improving the service life of furnace and energy saving. refractory is generally required to have the following properities: 1, it should be equipped with the properity of no deformation and melting under certain temperature. 2, it should be equipped with the neccessary structural strength without softening deformation in high temperature. 3, volume stability at high temperature, brick body won't be deformation or cracked due to expansion and contraction; 4, not broken and peel off under rapid changes of temperature or uneven heating; 5, resistant to chemical erosion of molten metal, slag and furnace gas,etc.

Q: How to classify the grade of wall fireproof and thermal inuslation matertial?: To sum up three versions of GB8624 (1997, 2006, 2011), fire?rating of external wall thermal insulation can be basically divided into: A1, A2, B1, B2, B3 and other levels. Specific division has many technical indicators to judge. It can't be said for a moment. It is very professional and technical. For details, please contact Qingdao Shanfang Instrument. They specialized in tester of fire?rating of external wall thermal insulation materials.

Q: What types does soft fire prevention materials have?: Soft type fire resistant species. Finishing fire retardant paint, component fire retardant coating, fire-resistant coating for steel structure and othe kinds of fire retardant coating. Flame retardant plastics and its products, textiles, building materials, flame retardant fabric and exterior wall thermal insulation system products, floor materials, such as various types of fire prevention materials;Fire prevention board, fire doors, fire prevention, fire shutter, fire glass window frame, elevator doors, ventilation pipes, fire blocking material, fire smoke exhaust fan and other kinds of artifacts (resistance) fire prevention.

Q: how to classify Insulating Refractory ?: Low-temperature thermal insulation materials (less than 600 degrees Celsius): medium temperature thermal insulation materials such as diatomaceous earth, asbestos tile (600-1200 degrees C): high temperature thermal insulation material vermiculite, light clay bricks(greater than 12,000 degrees Celsius): Lightweight corundum brick raw materials: Clay, high aluminua, silica, magnesia

Q: can slag tailings be used to be the base materials of refractory materials ?: perhaps not, because it has many pores.

Q: What are first rate fire resistant window materials?: Natural environmental protection, non-poisoned, non-peculiar smell, non-radioactive; non-combustible, fireproofing, moisture-proof, corrosion-resistant; easy construction, lightweight, high strength, www. jsxsmy.
