Introduce The Main Stuff Of Brick Simple Machine
At present, the production of brick simple machine based mainly on the use of raw materials for the and ordinary sand, synthetic get down aggregate(such as enlarged perlite materials, clay clayware material and fly ash stuff), cancel aggregates(such as pumice stone, volcanic slag and zeolite), heavy-duty run off lightweight Dust Collector Manufacturers aggregate(such as fly ash, cinder, coal impulsive combustion, coke slag, swollen slag slag and calcium string of beads) and other get down harsh combine Dust Collector.
1. cement: The more than 32.5 ordinary bicycle Portland , portland cement(GB175-1999) and Portland Slag Cement(GB1596-91), in the main used when the summertime product of slag . Should not be used pozzolana cement and fly ash cement.
SiO2 of ash at all levels greater than 40, Al2O3 of more than 15, bulk density of 516 107kg m3, subatomic particle density 1800 2400kg m3. In superior general, should use Ca, dry fly ash, which Gray acirc; hellip; nbsp;and acirc; hellip; iexcl; for more than 13MPa potency grade blocks, which can only be used for fly ash acirc; hellip; cent; volume raze of the lug is not greater than 10MPa.
Second, carbide: carbide is the world power pit(CaC2) Preparation of run off generated when alkyne. Carbide slag and hydrated lime in the composition and nature of similar, Ca(OH) 2 content normally 60-80(dry footing). Wet work system of rules in China to take more than acetylene, carbide high water content, undiluted by hurry can be used. Carbide hair color blue, a cold-shoulder odor, but atoxic. If there is no alternative to carbide can be used recently lime, generally do not use hydrated lime, lime if necessary to pre-grinding, thinness 0.080mm square up mesh sieve is not more than 25 margin. Requirements operational unslaked lime calcium oxide content is not less than 70, the higher the better, if less CaO content can increase the lime . Lime in the MgO lt;4, otherwise the product easy to split. Power plants, chemical plants released lime waste, or husk powder can also be used in target of used.
4, Gypsum: Gypsum is available to need more than 65 atomic number 20 sulfate, also available phosphogypsum(phosphate plant food manufacture, solid state run off, of which P205 less than 3) instead.
5. slag: fly ash and its main components and the same superficial density 600-900kg m3, subatomic particle denseness 1100-1800kg m3; loss on ignition le; 20, MgO content of less than 4, CaO of less than 5, SO3 content of less than 4, loudness stability test pass, subatomic particle size 0.16-10mm, the thinness modulus shall be between 2.4-4.2.
6. sand: According to the thinness modulus(Mx) can be dual-lane into coarse-grained sand(Mx is 3.7-3.1), sensitive sand(Mx is 3.0-2.3), fine sand(Mx to 2.0-1.6) and fine sand(Mx to 1.5-0.7). This product fineness modulus of sand between Mx is 3.7-1.6, the mud should be less than 3, should take in the river sand.
7. gravel: amaze or pebbles, the size of greater than 5mm, less than 8mm.
8. heavy-duty run off: including fly ash, slag, waste slag, tailings, slag, twist run off(slag brick, concrete residue), coal and so on. The heavy-duty waste residuum can be used in conjunction with its technical requirements are as follows: the residuum of ignition system loss no greater than 20, SO3 le; 2, the balance of the sand of subatomic particle size 0.3-1.3mm, 0.1mm pulverize of le; 20 the following may on behalf of the sand used; the remainder of the gravel particle size of 3-15mm, mud content le; 3 when used instead of vex. The waste cycle of 13 angle loss.
Coal is the roof, floor and the seam in the rock. Coal is not a I rock, but a admixture of carbon material and rock, which there is unstableness, burning coal to spontaneous combustion or after the use of colored, self-generated combustion is not a moderate coal emollient coefficient of 0.8, stewed loss rate less than 5, ignition loss no greater than 5. Slag should be placed more than 6 months, SO3 of not more than 1, and may not have tear apart, weeds and so on.
Calcium high-temperature furnace slag is a whirlwind of liquid slag, its temperature is usually in the 1200-1400 acirc; bdquo; fnof;, slagging from the fathom when I overflow by irrigate extinction, water quenching burst into a 2-10mm of solid state particles of solid water slaked slag as slag or liquidness calcium rest, also called Slag, slag containing calcium and other active components CaO, SiO2 is high, is still determined by the detection of non-active material. Calcium slag quenching by irrigate extinguishing, the particles exist within the cracks and intramural stress, big sandy granule, modest granule was very strong, so use the atomic number 20 residual must be impoverished.
9. unstable slag: a volcanic volcanic eruption of the material, porous, jackanapes and temper and strong features, better insulation, heat insulant, sound insulating material effectuate. Natural wadding denseness 580-800kg m3. Crushing effectiveness 3Mpa around.
10. pumice stone: It is a cancel jackanapes combine. Packing density 350-800kg m3, stifling strength of 1.6Mpa. So, as their stifling potency low pumice stone, pumice stone concrete strength is not so high, but its good caloric insulant.
11. get down combine: including ceramic clay, fly ash ceramic, perlite, Floating Beads, Shale, pumice, unstable slag line(GB T17431.1-1998) requirements, the level bes ingrain diameter 10mm(fineness modulus of 2.3-4.0 is appropriate) with clay content lt;3.
12. JFS activator: JFS activator is one of the core stuff of this product, its full activating of fly ash, some of the potentiality of industrial waste residuum will play a unhesitating role. Verified by product practise, JFS activator self-made, less , the use cost is not high, can significantly trigger off the activity of fly ash and slag to better the density of the brick simple machine, impermeableness, ice underground, stableness, water resistance and shrinkage control, qualification the lug significantly multiplied effectiveness and lastingness.
