Q:how to use boiler fireclay
Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.
Q:What is the use of refractory?
It is fire-retardant and insulated.
Q:how long is the fire endurance of plasterboard?
fireproof endurance can reach a maximum of 4hours, suitable for a variety of public buildings firewall, and partitions for public exit passageway, reaching standard level of fireproof. the lightweight partition made of gypsum board and steel stud is mainly for dividing architecture space. Rock wool can be filled in the mddle according to its design requirements, using different series of gypsum board, steel stud. the walls may have fire resistance and sound insulation property of various degrees.
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.
Q:What refractories are resistant to fluorine gas?
It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
Q:What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.
The refractory that you want is high temperature furnace which you can buy from the market.
Q:I want to know what is the slim in the refractory bricks
lining brick and refractory clay in the teeming ladle; high alumina brick, high alumina lining brick and high alumina refractory mortar can make cement kiln and glass melting furnace in the building materials industry for anti-slide. Taiyuan in Shanxi province is the famous place of origin; hard paste in the refractory clay is used as blast furnace refractory: // b, in agriculture as a fertilizer high alumina clay is also used in oil wells, which generally do not dip in water; accounting for 2/3 of abrasive products in the metallurgy, hard and semi-hard clay can be manufactured as ceramics for daily use. what you said should be slime. High-alumina clay can be resistant to high temperature after calcination! Refractoriness refractory clay refers that the refractoriness is more than 1580 ℃ with greater hardness and specific gravity and high refractoriness. except higher refractoriness, such as aluminum sulfate, the dosage accounts for about 70% of refractories; refractory clay and high alumina fused cast brick are widely distributed in China.
Q:What is the strength of high strength refractory material?
With the help of high temperature and load, refractory material deforma to a certain degree of temperature from the beginning of deformation (load softening point), known as high temperature structural strength or high load softening temperature. It is a the ability to resist deformation ih high temperature and load at the same time. The nature of the high temperature is very improtant for selection of a furnace building materials under the effect of high temperature and force.
Q:What are the characteristics of the carbon composite refractories?
The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag
Q:Who knows what material is in the center of fireproof rolling curtain?
Material and the type high silica cloth as curtain, side rails, with galvanized steel in its end and stainless steel two kinds of materials with double curtain in the end I hope my answer can help to you
