Q:What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?
The combustion performance of materials could be divided into: A( noninflammability), B1(flame retardancy), B2(flammability), B3(inflammability). Building materials are divided into four ranks according to these properties. 1. In accordance with Code for Design of Building Fire Protection(GBJ16-1987)(revised edition in 2001), fire hazards in producing and storage can be divided into five types. In Fire Prevention Code of Petrol Chemical Enterprise Design(GB50160--1992)(revised edition in 1999), classification of fire hazards is also achieved according to the hazards of materials that have been using, producing and storing. Measures in prevention of fire explosion could be taken from the perspectives of fire separation, fire resistance level of structures, allowable floors, safe evacuation, and fire extinguishing facilities based on different levels of fire hazards. 2. Four fire resistance rating of buildings are listed in the book Code for Design of Building Fire Protection. And specific stipulations are made to the fire resistance of main elements of buildings, such as bearing walls, beams,pillars, and floors. When designing a building, if permitted, refractory materials of high-rank should be adopted in those buildings which have high potential fire hazard and a lot of combustible material and valuable equipment. While making sure fire resistance rating, the duration of fire resistance of each elements should meet its requirements.
Q:What is the principal part of silicious refractory material
blast furnace hot blast stove and ceramic tunnel kiln vault, etc., the softening temperature under a fixed load is high (1690-1710 degree), glass melting furnace, lightweight silica bricks and generally the silicon dioxide is greater than 93% and used above the 600 degree. I had undertaken to complete the 50,000 tons over two advanced silica brick production line design. It is a typical acidic refractory. At present, it is mainly used to coke oven which the masonry operating temperature is higher than 600 degree, with good acid resistance of slag erosion, including silica brick, good thermal conductivity, high thermal vibration stability, product with fused quartz, close to its refractoriness silicious refractory SiO2 which is as the main component of refractory products.
Q:What are the materials of class A fire resistant window?
Environmentally friendily, non-poisoned non-peculiar smell, non-radioactive; non-combustible, fireproof, moisture-proof, corrosion-resistant; easy to operate, lightweight, high strength, themal insulation, sound insulation; able to be cut, planed, sawed and carved. It also meets GB8624 -2006A1 level non-combustible standards. Lightweight, high strength, anti-aging, corrosion resistance; meeting the GB / T20285-2006 Opium (AQ1) safety and environmentally friendly products; Foamed fire door core board specifications: 2100 × 900 × (26 ~ 65) mm; 2050 × 850 × (26-65), and many other specifications. I hope my answer can help you.
Q:What is the common inorganic fireproof and thermal inuslation matertial?
1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3 combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), sea capacity module and vitrified micro bead. (Hope I can help you! Hope you adopt. Thank you! )
Q:How many refractories are there for boiler above 1200 ℃?
Ordinary clay brick is for burning layer, red brick for external wall, light clay brick for thermal insulation layer, built by clay refractory mortar. Sindeyuan Refractories.Hope you adopt. Thank you. In fact, there are many manufacturers producing furnace burden. We has been using products of Huaheng, which are anti-erosion, easy to construct and can improve production efficiency, reduce steelmaking cost.
Q:For refractory, why is it necessary to store the first mixing materials for some time under proper moisture and temperature?
It is mainly to remove gas form chemical reactions in the pug, give full play to plasticity and binding properties of combined, and store unburned brick whose cememting agent is phosphoric acid or aluminium phosphate for some time under proper moisture and temperature. For example, to avoid the formed bricks in the initial stage of drying and firing form cracking due to hydration of calcium oxide. Mixing materials is to store the first mixing materials for some time under proper moisture and temperature in order to improve the evenness and moldability of pud, such as making the distribution of combined clay and water more even. The length of storing chiefly depends on the process requirements and the characteristics of blanks. For the producing pug of high temperature kiln furnitures, the storing time is longer. The function of storing mxing materials varies with different natures of blanks. For honeycomb ceramics, it is to fully digest calcium oxide in blanks. For storing magnesia brick blanks containing much calcium oxide, it should be stored for some time in proper humidity and temperature.
Q:I wanna ask what are the acidic refractories?
You can look at these: (1) silica brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity. I hope it is useful!
Q:what's the requirements of refractory for forge furnace?
operating temperature of forge furnace is 1000 ° C, reasonably choosing refractory for build furnace has an important meaning for guaranteeing the normal operation of the heating furnace, improving the service life of furnace and energy saving. general requirements for the properities of refractory: 1, it should be equipped with the properity of no deformation and melting under certain temperature. 2, it should be equipped with the neccessary structural strength without softening deformation in high temperature. 3, volume stability at high temperature, brick body won't be deformation or cracked due to expansion and contraction; 4, not broken and peel off under rapid changes of temperature or uneven heating; 5, resistant to chemical erosion of molten metal, slag and furnace gas,etc.
Q:Does refractory belong to stone, building materials or other?
Refractories belong to organic non-metallic materials.
Q:What problems should be paid attention to while using refractory materials under a controlled atmosphere?
Pay attention to the performance of the materials, and the use of non oxide materials!
