Abstract

Secondary pelletization based on shell principle forms one layer of hard shell outside haydite to raise greatly pressure strength of haydite; and changing haydite core material can reduce greatly the volume weight. Combining the said two kinds of technology can produce easily various artificial aggregate for different requirement. The present invention has great significance to building material industry and building industry.

Description

A kind of composite haydite producing technology
The present invention relates to and a kind ofly manually gather materials--the production technology of-haydite is characterized in that taking the production technology of compound balling-up.
Haydite is a kind ofly manually to gather materials.Because the haydite goods have multifrequency nature and can utilize refuse, have the mechanical property more excellent again behind the replacement natural aggregate than natural aggregate, therefore draw attention day by day.But the technology of domestic manufacturing haydite is relatively backward.Making lytag with sintering process is example, the ubiquity complex process, and the energy consumption height, defect of high cost, unburned manufactured haydite exists unstable properties, intensity difference, cost height, once invests big defective.
The present invention utilize its power of the stressed back of spherical shell at first be along spherical shell to around diffusion principle, in the haydite manufacturing processed, select suitable gum material to form the firm shell of one deck, thereby reach the purpose that increases substantially the haydite cylindrical compress strength at the haydite outside surface by the method for twice balling-up.By changing stamen material in the haydite, haydite unit weight is descended.Both combine just may create and adapt to manually gathering materials of various building requirements.Bottom illustrates its good characteristic with example:
(example one): sintering legal system lightweight spavin haydite.Interior stamen is with mixing γ=1.05g/cm 3Spent pulping liquor 15%, pan-pelletizer is multiple with the clay 80% of equivalent through the ball mill grinding under going into after 85%, balling-up of original state flyash, not coal 20% sheating material.Can make the lightweight coarse aggregate through the shaft furnace sintering.Its loose volume weight is 700kg/m 3, cylindrical compress strength is 6Mpa.
(example two): sintering legal system lightweight spavin haydite.Interior stamen is used spent pulping liquor 30% instead, powdery plant stalk 60%, clay powder 10%.After the balling-up multiple with etc. heavy clay 90%, the sheating material of coal 10% not.Behind the sintering, loose volume weight is 450kg/m 3, cylindrical compress strength is 7Mpa.(example one) compared, and unit weight descends and the intensity raising.
(example three): unburned knot lightweight meal flyash haydite.Interior stamen go into after with a balling-up of 100% flyash down pan-pelletizer multiple with and 85% heavy flyash such as interior stamen, 15% unslaked lime formation shell.Take to prevent behind the drying step maintenance 12h with containing co 2Gas carries out charcoal acidification 12-24h.Loose volume weight 750kg/m 3, cylindrical compress strength 9Mpa.
(example four) unburned knot lightweight meal flyash haydite.Interior stamen is used the pearlstone 95% that gives moistening processing earlier, slaked lime powder 5% instead.Multiple after the balling-up with 425 of weight such as interior stamen #Cement 30%, the sheating material of flyash 70%.Behind the moist maintenance 3d, natural curing 28d.Loose capacity 300kg/m 3Cylindrical compress strength 9Mpa.
The unburned connection of (example five) sinter bonded is produced lightweight crude pottery grain.Interior stamen uses after pulverization process particle diameter to be not more than the corn core of 10mm, multiple with the thick clay 90% of 2mm, the sheating material of plant stalk powder 10%, the stamen spheroid was multiple with by 85% flyash by (example three) method again in product after the sintering processes was done, and the 1.5mm extended envelope body of 15% levigate living stone class powder also carries out the charcoal acidification.Loose volume weight 350kg/m 3Cylindrical compress strength 9Mpa.
Utilize compound method, adopt different raw materials can also make other multiple have different unit weights and The composite haydite of mechanical property is to satisfy the special requirement of modern industry and civil buildings. With traditional haydite worker Skill is compared and is had more widely applicability.

Claims (6)

1. a composite haydite producing technology is characterized in that this haydite is to be composited more than two-layer at least, and each layer proportioning raw materials used and raw material has evident difference.Made haydite can adopt sintering method or unburned knot method to make product.Interior stamen mostly is the waste resource or the light material of industrial and agricultural production.The shell of sintering process haydite is the clay class material that is mixed with combustiblesubstance.Unburned connection haydite shell many to the hydraulicity or air-setting gum material in conjunction with comprising that other fine aggregate materials of flyash make.
2. composite haydite according to claim 1, its inner layer material can be inorganic materials, also can be organic materialss.
3. composite haydite according to claim 1, stamen spheroid can be with the spheroid of rolling balling method shaping or the spheroid of almost spherical in it, also can be without balling technique irregular spheroid, polyhedron that just size is more or less the same on three-dimensional.
4. composite haydite according to claim 1, each layer that except that interior stamen and shell, increases, or for stamen out-of-shape in considering, in order to reduce the sheating material consumption, or for change shell with the interior intensity of the ball stamen that layer formed that is equipped with to satisfy haydite in the requirement aspect economy, physicals, the technical indicator.
5. composite haydite according to claim 1, other each layers except that interior stamen all must or be compound to the method for soaking on the outside surface of preceding one deck by the moulding of rolling balling method.
6. the curing condition of composite haydite according to claim 1 is the curing condition decision that requires according to used gum material material and process for making fully.
