Q:What antioxidant will be used in refractories?
Antioxidant: Si, Al, Mg, Ti, AlSi, AlMg, SiC, TiC, ZrC and these metal nitride, boride. Sintering agent: different mechanism, Cr2O3 to promote the sintering of alumina;CaO/MgO style promote ZrO sintering;Siliceous ramming material to add boron bottles, magnesia coating and clay, etc.
Q:How long is the fire-resistant time of fireproof wooden door?
Wooden thermal insulation fireproof door using flame-retardant timber or flame-retardant timber products to make door frames, skeletons of door leaf, door panels. If the door leaf need to be filled with materials, the filling materials should be fireproof thermal insulation materials which is non-toxic and harmless to human body, and matched fireproof door composed of fireproof hardware. Use doors without age limits.
Q:How to solve the shell, the crack problem of refractory material in the process of forming.
Pressure mode and number of pressure control "spallation". 2, multiple pressure, pressure degree and discharge way: 1, reduce friction, choose appropriate, than big pressure disposable pressure produced by the plastic deformation, allocate reasonable grading, internal and external friction, reduce billet particles and high die wall bright. 4.--- solve the light one firstly. --moisture content being too high easily cause spallation - the compressibility of water is small and have certain elasticity, appropriately to extend the pressuring time is beneficial. The material can produce large plastic deformation under the effect of continuous load. The right amount of lubricant. - body under the condition of less pressure but long effect time molding. Mould structure is reasonable and improve billet natural stacking density. 5.3, measures to improve the unburned brick molding quality. Many times continuously pressure relief is better than one-off sudden unloading, and controlling the appropriate moisture content;- - is beneficial to air overflow.
Q:What are the models of refractory cables?
The models of refractory cables: NH-KVV22 copper core flame-retardant PVC insulated and fire retardant control cables with steel belt sheath NH-KVVRP copper core flame-retardant PVC insulated and fire retardant shielding control cables with steel braiding sheath NH-KVVP2 copper core flame-retardant PVC insulated and fire retardant shielding control cables with sheath and steel belt wrapping NH-KVVRP2 copper core flame-retardant PVC insulated and fire retardant shielding soft control cables with sheath and steel belt wrapping NH-KFF copper core fluorine plastic insulated and fire retardant control cables with sheath NH -KFFR copper core fluorine plastic insulated and fire retardant soft control cables with sheath NH -KFFP copper core fluorine plastic insulated and fire retardant shielding control cables with sheath and copper wire braiding
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:Are there any differences between insulation and refractory materials ?
I will explain to you in a simple way. Refractory materials can resist more than 1200 degrees, some of which are not insulation materials, such as firebricks, which can directly contact with heat source, has little insulation effect. Ceramic fiber, high silica, etc. are all refractory materials which can insulate. Insulation materials with poor performance usually is lower than 800 degrees, which have large thermal resistance, and low thermal conductivity, high porosity. Thus they reduce the thermal loss. To put it simply, insulation materials store most of the heat and only let a small part of heat lose through the air, thus the heat has been isolated. Glass fiber, rock wool, flexible material for thermal insulation, etc. I hope you can understand it.
Q:What kind of refractory decorative board has good quality?
Formica, Grignard, Wilsonart, Yami Home, Germany Board and Priscilla Board are all good choice. They are the high-end brands in fireproof panel. Hope it is helpful to you.
Q:Does anyone knows which company produces the better refractory materials?
A:Building Materials Company of Guangzhou: Near the Baiyun District, Baiyun District, Guangzhou Road, North Road. B:Guangzhou Research & Development Co., ltd.: Liwan District Fengyuan road No.90 in Guangzhou City C: Huitailong decoration materials Co., Ltd.:the 30th floor of No. 111 Pacific Center, Taikang Road, Yuexiu District Guangzhou City D:Guangdong metal materials company: Near Qishan Road, Tianhe District , Guangzhou city.
Q:How many kinds of fireproof materials are there in the market?
I wonder that how many kinds of fireproof materials are there? Does anyone know about it, please tell me, thanks
Q:How can refractory materials be divided?
Refractory materials in China can be roughly divided into refractory products and unshaped refractories.
