China downdraft kiln bauxite Al2O3 made in China

Q:Who knows the fire resistant level of the rock wool color plate?: Hello; Same with other unprotected steel, the fire endurance of the color steel?plate is generally 15 minutes. It is not a fireproofing material, let alone fire resistant level. If the color steel plate has sprayed fire retardant coating and the thermal insulation filling material in the core is rock wool fiber, it can achieve A level fireproofing requirements. The color steel?plate refers to the painted steel plate, which is a steel plate with organic coating. The color steel board is divided into the single plate, color steel composite board, floor support board, ect. It is widely used in large public buildings, public plants, portable dwelling, and integrated housing walls and roofings. I hope that will help you.

Q:Refractory net: Foreign enterprises created not only for profit, but a career, hope to be able to last forever; domestic, especially private enterprises, most of them do not have such a vision, only to a loophole, cash, so never to do this industry.Welcome to discuss the statements of a school.

Q:How many grades of fire?rating are there for interior decoration materials?: It can be divided into structural material and base?material based on materials. It can also be divided into flammable, flame retardant and non-combustible materials based on fireproof types. There is no fire?rating for materials. But lengths of time of flammability limits are different.

Q:What are the types of refractory sealant?: According to the environmental temperature of the region, it is divided into stpl-1 type, stpl-2 type, stpl-3 type. The three models are respectively applied to sealing repair of regular and irregular crack in asphalt / cement concrete roads, highways, airport runways, which are of different temperatures. Stpl-1 type: It is suitable for pavement temperature (0℃to 80 ℃) stpl-2 type: It is suitable for pavement temperature (-15℃to 60 ℃) stpl-3 type: It is suitable for pavement temperature (-30 ℃ to 40 ℃)

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.

Q:The fire prevention board line is made of what material?: Crural line: wooden, in the market, there are sjoiner woodblock, peach wood and artificial engraving. The second classification is stone and the most used one is the marble graved or ceramics well-made one is taken as the first choise. Its price is a little bit expensive than the wooden one, but also a suitable choise. Condole supports: It has various category. The general furniture choose plaster and anti-firing plate and the other also have a choice of steel. You can make a suitable choice according to the need. If it is contracting project, it depends on your project specific plan and funds plan. In a word, beauty and harmony should be given priority since it is the source of design.

Q:The difference between refractory and thermal insulation material: In simple terms, refractoriness is different. The refractoriness of refractory is high while that of insulation material is low.

Q:How many external wall thermal insulation fireproof material are there: External wall thermal insulation materials are generally divided by the burning grade, into class A, B grade. Grade A is non combustible material, grade B is combustible material. Class A which can be divided into thermal insulation mortar, bakelite plate, rock wool plate, foam cement plate etc.. Insulation mortar is relatively good, easy for construction, convenient, low cost, but its production process is too simple, so it is prone to fake. I recommend you to find a large manufacturing factory that posses complete procedure, for example, provincial production record, the provincial use record, municipal record, tset report at or above the provincial level, state fire proof report, design drawings of office building. product will not be safe if there is a lack of any of these documents. Burning level for henolic is uaually class B, but class A2 can be reached if a thin layer of mortar is applied on the suface,(A1 is the highest level of fire safety),intensity of phenolic is not high, finger pressing will leave a pit on it. if classified according to kilogram, raw material differs greatly every 10 kilogram. Rock wool is also classified by kilogram, general using 150kg wool. Rock wool are now comprounded with average strength. It will easily absorb water, having trouble applying paints. Foam cement strength is not high, easy to absorb water, It is not resistant to falling. It costs low, only used unless little profit can be made, Do not use it if worrying accidents would happen. These materials can be firstly burned, The palce the sample into water to see if it will dufuse at last. External wall should stand up to wind and rain. In terms of thermal insulation, they are almost the same, shows little differences on design thickness.

Q:How is refractory material made?: It is made from yellow mud and water.

Q:what is steel fire door made of ?: 1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance. This is a steel door.
