- Q:Who can introduce the difference between galvanized fireproof?coatings and steel structure fireproof materials?
- Steel structure with heat galvanization has a process requirement, which is to spray fireproof coatings. Fireproof coatings have different functions and purposes from galvanized process. When the steel surface derusted, it generally needs to brush rich-zinc primer before spraying fireproof coating. Fireproof coating plan itself includes anticorrosion plan, and fireproof coating is just a layer of coating plans, which is an intermediate layer in general. Fireproof coating plan generally includes primer, fireproof coating and finishing paint. Some fireproof coatings can be directly painted on the bare steel elements without primer and finishing paint.
- Q:What is the new fireproofing standard of external wall thermal insulation materials?
- 1, The height of fire barrier zone is not less than 300, and the thickness is same to the external insulation system; 2, the horizontal dividing joint should be set on the boundary between fire barrier zone and thermal insulation system; 3, Fire barrier zone is usually set in the horizontal direction, the fire barrier zone should be set above the door and window openings, the distance between the low edge of barrier zone and upward side of the hole should not exceed 500mm; 4, The construction of fire barrier zone insulating layer should carried on from bottom to top with EIFS insulating layer, which is not first leave the place in the EIFS insulating layer, and then paste fire barrier zone insulation board; 5, pasting the insulation board fire barrier zone insulation board and EIFS insulation board should be stitched closely, the width is more than 2mm gap application EIFS insulation materials or fire-retardant foam polyurethane padding;
- Q:Where do China and foreign countries do more refractory materials?
- Zhengzhou real gold refractory materials Co., Ltd. specializing in the production of non-ferrous industries, glass kilns, cement kilns with a variety of refractory materials, factory direct sales, reasonable prices.
- Q:What's the maximum temperature that the refractory ceramic fiber cloth can endure?
- Ceramic fiber cloth is high temperature resistant and its continous use temperature can be up to 1000℃. It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment; and it is easy to install.
- 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:Why the refractories should be waterproof and wetproof
- The binding agent of many raw materials is water-soluble. It will be useless when meeting water.
- Q:How is the development of Xinmi refractories industry? What's its advantages and disadvantages?
- I don't know how it has developed. Its advantage is the coal industry. You have to know the generating capacity in Xinmi thermal power plant first, and then you will know their coal cinder yield, after all, this is the raw material. Xinmi is not far away from Zhengzhou. The real estate in Zhengzhou is still good. I'm not sure about the others.
- Q:What are the specifications of refractory kilns ?
- There several points need to be noted ① selection of body material. The refractory lining of the front kilneye turns gelid and hot rapidly and frequently, so the temperature is in the range of 800 ℃ ~ 1250 ℃, allowing it to withstand wear of the cement clinker and corrosion of the cement base. The body material of castable refractory must be chosen according to its service conditions, in order to ensure that it is cheap and easy to use. ② the selection of admixture. Shapeless refractory materials are typical in-situ reaction refractories. Therefore choosing admixtures is very important and must ensure workability, baking performance, and excellent material properties. Admixture for Kiln refractory castable includes dispersants, accelerators, plasticizers, sintering agent, bulking agent and antidetonant. Materials of sintering agent are animate clay, zirconite, titanium dioxide and Peng compounds. Such substances produce a certain amount of mullite crystals, zircon phase, titanium aluminate crystal and inconsistent melting compounds (2Al2O3 ? B2O3), etc. under the operating temperature and in situ reaction. They are accompanied by volume expansion and microcracks, enabling it to compensate for the sintering shrinkage, so that the casting material can have sintering strength, corrosion resistance and good thermal shock resistance. In summary, the refractory castable material for the rotary kiln shall be determined in accordance with its service conditions. It is recommended that clients should also communicate with technical personnels and sales staff about some facts of the rotary kiln when buying it, so that they can get the satisfying rotary kiln.
- Q:Urgently!! Refractory problems, online, etc.
- I feel that is the coating package, the coating of water is too large, the retaining wall in fused powder hydrated, can not produce strength under high temperature. What do you think?
- Q:What's the classification of flameproof glass, the refractory time of fireproofing glass.
- who knows the classification of fireproofing glasses, how long is the fire-resistant time?
