- Q: The fire prevention board line is made of what material?
- The line is a kind of composite stainless steel decorative profiles which outer layer is the matte frosted stainless steel plate and inner liningl is wooden material. It do not need to render with fine wood and also need not to buy a stainless steel plate cutting, cutting, bending, such as multi-channel intricate process, processing production. It is convenient to install through the buckle button directly on the booth. When installation, it only needs to be bolt and plug to be fixed on the wallafter blanking cut. compared with the traditional wooden play crural line, the profile is more beautiful and firm, and environmental friendly. And compared with the traditional craft production of stainless steel line, it's cheaper and more convenient to install. This product is not only sitable to decorate in the family, but also is more suitable for the hotel, hotel, office building, and the application of all kinds of public places.
- Q: How long is the fire-fighting time of A class fire resisting window?
- Duration of fire resistance of fire resisting window: A class window is not less than 1.2 hours; B class window is not less than 0.9 hours and C class window is not less than 0.6 hours. Technical Requirements: 1materials and accessories (1) window frame structure adopts stell framework and wooden framework that have a certain strength to ensure integrity and stability. (2) steel framework and batten can choose galvanized steel plate or stainless steel The selection criteria meet requirements of GB12955 steel fire door general technical conditions in the provisions of article 5.1. The selection criteria of wooden framework and batten meet requirements of GB14101 wooden fire door general technical conditions in the provisions of article 5.1.1. Filling material of steel and wooden framework shouldn't adopt non-combustibility material. (5) fire-fighting glass can adopt testing-qualified product that don't influence fire resistance performance of fire resisting window. Light transmittance of glass is not less than 75% of the same layer common plate glass. (6) Sealing material between framework and fire-fighting glass should adopt Flame retardant material which can serve as fire-fighting and smoke-resistant when encounter fire disaster. (7) hardware fitting should accessories product that is tested to be qualified. 二. installation requirement: 1. When Party A takes over goods, he should check numbers, specification, grades and whether Accessories are Conformed and complete according to contract.
- Q: What the fireproofing materialare of the refractory kettle and where they can be sold?
- Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.
- Q: what's the fireproof levels of fireproof and thermal inuslation matertial?
- 1, organic materials: B level material is flammable, B1 level material is flame retardant. 2, inorganic materials: Grade A flame-resistant materials are divided into three classes and two kinds of materials.
- Q: Who knows how to divide the building fire grade and fire resistance grade?
- I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on. The judgment condition of the fire resistance There are three conditions for components' fire resistance limit to be reached, namely, the fire resistance limit of the building component: Loss of support and integrity; loss of time to fire the role of the time; as long as any of these three conditions is met, it will reach its limit of fire. Hope my answer will help you.
- Q: What kind of refractory materials are used in metallurgy industry?
- Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.
- Q: I am a manufacturer of refractory materials. I would like to receive some orders from abroad. I would like to know what foreign trade companies in Dalian place foreign orders abroad
- You don't give a cent to this question, no one will answer it
- Q: What are the requirements for the performance of refractory materials?
- Performance requirements for electric furnace lining refractory: 1, sufficient refractoriness and softening point. Because of eletric arc, the inner surface temperature of lining can be as high as 1500 to 1800 degree. 2, strong resistance to slag. Because the dust penetrate into the furnace through pore lining, and the refractory material subject to loss, leading to spalling. 3, good thermal and shock resistance. Because during steelmaking, opening door and lifting of the furnace will lead to sudden changes in the temperature of the furnace lining refractory material, so spalling and cracking may occur, damaging the lining premature. 4, enough strength, because the lining is impact during charging, tilted when vibration,and eroded by metal, slag and airflow. 5, the thermal conductivity shall be small, and the conductivity shall be low. The commonly used furnace refractories are dolomite brick, magnesia brick, high alumina brick, silica brick and magnesia ramming etc.. Because of different working conditions of the various parts of the furnace, the refractory materials are not the same.
- Q: What are the new refractories?
- There are many of them. We can talk face to face. Sichuan Province Deyang City Xinxin Refractories Co. 0838-2228543
- Q: who knows the technology of fireproofing material?
- 1, dealing mould, scrape and clean the thick liquid on the surface of mould with tin-coated steel scraper blade or plaster tool. 2, adjust laminator, according to the thickness of fireproof?panel, adjust each roller, keep them parallel. 3, ingredient, according to the requirements of recipe, stir the raw materials uniform with agitator. (usually we should add bittern firstly, stir it with modifying agent for 5 minutes, then add filler and stir for 2-3 minutes, finally add grogs and stir it to uniform) note: the stirring speed should be kept in 60-80 r/min. 4, place the cloth, place a layer of non-woven fabric and two layers of glass fiber fabric (mechanical spread fabric). 5, flitch, place the materials after compounding and stirring into stop gauge of laminator, then you can start up and produce continuously, it's finished product after finishing. note: the distance between two templates is 2-4mm.
