Q: What is refractory brick?: Capability1. Refractory brick is also known as firebrick. It is faint?yellow or brownish. Refractory brick with 770 ℃ at high temperatures is called for short firebrick. It is mainly used for building and smelting furnace. It is a refractory material made by fring refractory clay or other refractory material.

Q: Refractory net: The development of the industry of refractory materials is very good, manufacturers are also more and more, especially in the Henan Xinmi side, next to the factory factory, we had visited gold refractory material factory, the scale is very large.

Q: What is the requirement of refractory concrete for raw materials? What is the main principle of commercial mixing station?: Refractory concrete generally divided into three categories: lightweight concrete (used in insulation); refractory concrete (for refractory temperature requirements are not very high position, and can withstand a certain air scour); heavy refractory concrete (flow with higher requirements for refractory temperature parts, and can withstand a certain intensity). Mainly depends on the design temperature and the use of parts.

Q: How to use fireclay?: Actually, fire clay is not strong. Fireclay are all clinkers with no strength, also known as "blade mud". It is used as the filler with a thickness of not more than 3mm. Therefore, it can not be used for thermal insulation inside the furnace. Inner thermal insulation of the civil boiler can use "alumina cement", also known as refractory cement.

Q: What's the poured refractory material?: Frequently used poured refractory material: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia.

Q: Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?: The fire-resistant differences of B1- and B2-level extruded insulation boards are as follow: B1-level materials will be smothered as soon as staying away from fire, namely, they will be extinguished after leaving fire, or be put out in 10 seconds. B2-level materials will be in low-grade combustion, namely, the fire will not get wilder, and drippings will not ignite the filter paper. I hope my answer can help you!

Q: What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?: glass

Q: what is the material of fixed first rate fire resistant window?: Fixed first rate fire resistant window is produced by the steel sash windows, steel casement, fireproofing glass. Fireproof windows, is composed by steel window frame, steel casement, fire-proofing glass. it refers to the window which can isolate and stop the fire spreading. The fire window product is named after the main material of window frame and the window casement, window frames is made of steel, casement is made of wood or the sash frame is made of wood and the casement is made of fire window.

Q: What's the fire endurance of A grade fireproof glass curtain wall?: The following is fire endurance of A class fireproof glass curtain wall. Fire endurance of the fire window: A class fire window: no less than 1.2h; B class fire window: no less than 0.9h; C class fire window: no less than 0.6h. Technical requirements: 1. Materials and fittings: (1) Window frame should adopt the steel frame or wood frame with certain strength so as to guarantee the integrality and stability of the fitting; (2) Steel frame and mound layer can choose the galvanized steel sheet or stainless steel sheet. Its selection standard is in line with provisions of Article 5.1 in GB12955 "General Technical Requirements on Steel Fire Doors"; (3) Selection standard of wood frame and mound layer should be consistent with the provisions of Article 5.1.1 in GB14101 "General Technical Requirements on Wood Fire Doors"; (4) Filler material inside the steel frame and wood frame should be incombustible material; (5) Fireproof glass can choose the qualified product with no influence on the fire resistance test of the fire window, and its light transmittance should be no less than 75% of that of the ordinary sheet glass with the same layers; (6) Sealing material between the frame and the fireproof glass should use flame retardant material which can play the role of fire prevention and smoke insulation in case of fire. Hope it's helpful for you.
