Q:How to choose construction external wall thermal insulation and fireproofing materials?
Now external wall insulation decoration one board is more popular thermal insulation material. Low-carbon energy-saving insulation decoration board combine two constructions (decoration, insulation) into one, saving nearly ten processes,and construction period. Compared with conventional thermal insulation methods, it can increase construction efficiency one time by shortening 60% of the construction period. It integrates low carbon, energy conservation, decoration, fireproof and building aesthetic effect by combining like-dissolving-like binding system installation and bump fixed system, and under long-term cooperation of air handling system and waterproof system. It has excellent outdoor weather resistance, colour retention, alkali resistance, water resistance, scrubbing resistance, crack resistance and temperature change resistance, wear resistance, collion resistance and the paint film is firm and durable, with strong adhesive force and mould proof effect. It can provide all-dimensional thermal insulation, decoration, low carbon and energy conservation and fire prevention for construction projects.
Q:what's the standard of fireproofing material?
first, the classification of fire resistant levels of buildings, 1, the classification basis of fire resistant levels of buildings, the classification of fire resistant levels of buildings is one of the basic building fire protection technology measures, our national architectural design specification divides fire resistant levels of buildings into first, second, third and fourth class, first class ios the highest and has the most strong fire-resistant capacity, fourth class is the lowest and has the weakest fire-resistant capacity. Fire resistant level of buildings depends on the combustion performance and fire endurance of the components of the buildings. construction components refer to the wall, base, beam, column, floor, stair, suspended ceiling and other basic components of buildings. Combustion performance and fire endurance of building components are shown in table 4-11), the combustion performance of building components are divided into non-combustible component,hard-comnustible component,combustible component,according to their response to the fire. as for building components, non-combustible component includes wall column and base,etc; hard-comnustible component includes hanging bracket, suspended ceiling and internal pipe;combustible component includes doors and windows, suspended ceiling, decoration materials,etc.
Q:How is the performance of refractory materials?
It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project
Q:What a blast furnace refractories generally?
Common refractories often use silica brick, semi-silica brick, fireclay brick, high alumina brick, magnesia brick, etc. special materials often used are AZS brick, corundum brick, directly bonded magnesia-chrome brick, carborundum brick, silicon nitride bonded silicon carbide bricks, nitrides, silicides, sulfides, borides, carbides and other non-oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide refractory insulating refractory frequently used. material diatomite products, asbestos products, insulation boards. monolithic refractories have fettling frequently used, refractory ramming mixes, refractory castable, fire-resistant plastic, refractory clay, refractory gunning refractory projection material, refractory coatings, lightweight refractory castable, stemming etc.
Q:Do you know where I can buy refractories?
A Address of Guangzhou Lingnan Refractories Co., Ltd. : No.1069 Guanghua 1st Road B Address of Guangzhou Aolian Refractories Co., Ltd. :
Q:Why the refractories should be waterproof and wetproof
It is necessary to like magnesium carbon, waterproof and wetproof is more important. There is a variety of refractory materials, in general, basic is defective, and wherein the binder and additives water will lose their effect, the relationship is not very high aluminum large amount of water determines how much of the performance after the hydration will affect the strength and high temperature performance ;; hydration & quot, just need a little package like magnesium and calcium-based product itself readily react with water to calcium oxide, magnesium, chromium is not all the material goods have waterproof ordinary bulk materials need to add water before use
Q:How long does it take for refractory cement to solidify?
1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.
Q:How much is the content of boron carbide in refractory material?
Boron carbide is used in refractory material. For example, generally we could add 0.2% of boron carbide into magnesia carbon bricks. It is suggested that 0.5% is enough, because it has strong effect in boosting melt. It is said that 0.5% would be alright since boron oxide after oxidation belongs to material of low melting point, so the amount should be limited within 0.5%-1%,
Q:The performance of refractory material
The mechanical properties of refractory material include withstand voltage strength. The structure properties of the refractory materials include porosity, bulk density, such as thermal emission rate. The physical properties of the refractory materials include temperature conductivity structure performance, wear resistance, hiphotos, electrical conductivity, creep, the hydration resistance, adhesive strength.
Q:Firing high temperature kiln of refractory and internal temperature being as high as 1600 ℃, metal heat exchanger can't use, how to do?
Directly using silicon molybdenum kiln, the temperature is better. Now using the electricity is cheaper than the price of other fuels.
