Q:What are the construction measures of refractory material in winter? Please descriptive briefly.
Binding agent should be attaced great importance to when construction is conducted in winter. Generally if the bingding agent is water or cement, antifreezing measures should be taken.
Q:can slag tailings be used to be the base materials of refractory materials ?
perhaps not, because it has many pores.
Q:The manufacturing technique of refractory material
Melt blowing method is to melt the ingredients first, In addition, hiphotos, organic impurities, to be mixed, add sulfite pulp waste liquid into magnesia billet , ensure the accuracy of the product dimension. The products are mainly used for light refractory. then dry and fire with sintering to reduce the firing shrinkage of products, making it disperse into fiber or hollow sphere. The porpose of pre sintering raw material is to Sintering method is pre-sintering part of the raw material into clinker. such as adding binding clay into aluminum silicate blank
Q:What refractory material lead smelting furnace needs?
Q:who knows the technology of fireproofing material?
First: Firstly, you should produce the recipe and prepare the raw materials, for example, if you prepare to produce 1 ton, you should compute the recipe sheet of 1 ton producing; check whether the raw materials are complete; second: make the color and filler thick liquid; add water in order and proper auxiliary in a low speed, then put color and filler (generally we should firstly add something with large oil absorption), wash the meachine after putting the powder. Then seperate them for about 20 miutes in a high speed, until the fineness is qualified; of course, if you need sander, i think you only need sino-soviet differential powder material and non-obvious particles. Third: Paint mixing period: after making the color and filler thick liquid, reduce the roll speed into about 600 roll per minute, add emulsion and proper auxiliary, finally adjust PH and viscosity.

Q:Which brand of thermal insulating refractory is good?
Brands of thermal insulating refractory: 1, Armaflex(German brand). Manufacturer: Armacell thermal insulation materials (Guangzhou) Co., Ltd, Armacell thermal insulation materials (Suzhou) Co., Ltd. 2, Durkflex (American brand) Manufacturer: Durkee (Guangzhou) thermal insulation material Co., Ltd. Durkee (Wuhan) thermal insulation material Co., Ltd. 3, Aeroflex (Thailand Brand) Manufacturer: Aeroflex Polymer Technology (Shanghai) Co., Ltd.
Q:Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?
You can try the following way to give a brief introduction of the fire rating classification of external wall thermal insulation materials. 1. the building materials are divided into following categories in terms of combustion performance according to the national standard of GB8624-97. A-level: Incombustible building material: materials almost don't burn. B1-level: nonflammable building material: these materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building material: combustible building materials can play a certain role in flame resistance. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden column, timber roof truss and timber beam as well as stairs. B3-level: Inflammable building material: Inflammable building materials are highly flammable with no flame retardant ability. The fire risk is high. 2.The exterior wall thermal insulation materials can be classified according to fire rating. 1). Insulation materials with A-level combustion performance: rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2). The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene board(XPS)/ specially-treated polyurethane(PU), phenolic aldehydegelatine powder polyphenyl granule,etc. 3). Insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc.
Q:How about the prospect of refractory material?
Area depends the market. Resource-based industry
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:What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?
Fireproof of steel components can adopt outsourcing concrete (or laying bricks method), fireproof coatings, fire prevention board coated and composite structure. Anti-firing plate can be divided into the fire protection lamella thickness plate and thin plate. Fire protection lamella thickness plate is of 20 ~ 50 mm. There are mainly calcium silicate and decayed stone of fire prevention board fire board, main varieties KB board, CF board; Fire sheet thickness is between 6 to 15 mm and the main varieties have short fiber reinforced cement pressure plate, fiber reinforced ordinary calcium silicate board and glass cloth reinforced inorganic plate. I hope you can be satisfied.
