FUSED SILICA POWDER 270MESH

Q: How much is refractory spraying coatings?: This depends on whether you use the thin coatin or thick coating. Then it depends whether you use an aqueous coating or oily one. Usually thick aqueous coating is 2-3 dollars per kilogram. While the thin is six or seven dollars per kilogram. The oily coating is more than ten dollars. The prices obtained from the Internet is for reference only.

Q: What are the applications of refractory in petroleum?: It can be used in chemical filler. For general process, some insulation parts also need to use refractory.

Q: How many hours of the fire endurance time of the rock wool laminboard?: The fire endurance time of the rock wool laminboard is generally adout 1 or 2 hours.

Q: How to hang the suspended brick in the refractory masonry?: First you can weld the metal fastener of the suspended brick and then hang up the brick.

Q: What are the insulation fireproofing materials?: Insulated shoes, insulated gloves, tape (cloth, plastic, as well as waterproof) yellow wax tube, mouth care, fireproof (ie asbestos cloth is sold by jin) there is pressure-caps black tape, waterproof tape ,casing. There are glass fiber needle felt is widely used in electrical, chemical, construction, transportation, automotive and other industries interlayer insulation and silencer system, and used as an insulating fireproof material.

Q: Where is refractory used? Thank you!: Currently, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, ceramics and other industries. The current definition of refractory does not only depend on whether the refractoriness is above 1,580℃.

Q: What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?: The thickness of steel structure fire retardant coating hasn't been regulated in the steel structure application specification (CECS24:90). The above thickness refers to a certain thickness that must (at least) achieve a certain time of the fire resistance. The thickness of fire-retardant coating in engineering is generally determined according to factory inspection report. We use thin steel structure fire retardant coating: 2.5 hours' fire resistance with the thickness of 4.9 mm; 2.0 hours' fire resistance with the thickness of 3.5 mm; 1.5 hours' fire resistance with the thickness of 1.75 mm; 1.0 hours' fire resistance with thickness of 1.17 mm. I hope I can help you.

Q: What is the main material of fireproof wooden door?: Fireproof wooden door has a lot of materials! including imported timber decorative effects: utilizing the diversity and easiness to cut of the timber, with all the decorative characteristics of the timber. Material selection features, door frames: Using high-quality hardwood, such as imported miscellaneous wood, camphorwood, lauan, hemlock, etc., insetting fire and smoke proof adhesive tape

Q: Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?: There is no necessary connection between them. Different fire resistant ratings of bulidings require different fire endurance of different elemements of buildings. According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level. "Building Regulations" mention that fire resisting shutter can be used as partition of fire?compartment in those places where setting firewalls is not so easy. When using fire resisting shutter whose fire endurance doesn't include unexposed surface temperature rise, it should install closed independent automatic sprinkler system for protection on both sides, and the sprinkler sholud last at least 3 hours.
