Abstract
The invention relates to a super-light ceramic granule, belonging to construction material preparation field, about artificial light material preparation. It takes sludge from river, lake and reservation as raw material and takes shale as auxiliary material. It makes use of the heat from fusible organic component during baking and thus shortens the baking time and saves energy consumption. It controls process of de-carbonization and sintering and expanding to produce super-light ceramic granule. The product is mainly used as bone material for concrete temperature insulation, super-light wall material, block super-light material, temperature insulation material and packing material for wastewater biological treatment.
Description
Technical field
The invention belongs to material of construction, be involved in civil construction project insulation or the concrete artificial lightweight aggregate of structural thermal insulation; A kind of Superlight ceramsites and compound method thereof are provided.
Background technology
Artificial lightweight aggregate haydites of book structure in 1913 can replace common centimetre sandstone with light-weight aggregate and gather materials since the U.S. comes out, and to reduce the method that normal concrete is conducted oneself with dignity and improved a series of performances, is subjected to the countries in the world common concern.
As everyone knows: light-weight aggregate can be divided into: natural light-weight aggregate, industrial waste light-weight aggregate and artificial lightweight aggregate.Artificial lightweight aggregate is to be main raw material with clay, shale etc., fire the light high-strength haydite that forms through processing, because its raw material sources are extensive, product performance can be regulated according to purposes, therefore since this comes out in this world, its research and development are subject to people's attention always, and the development of artificial lightweight aggregate has become the item key of a national development light-weight aggregate level.
Along with in China flourish of artificial lightweight aggregate industry, yet, ruin ground brickmaking, ruin the field granulation, use clay in a large number, expend land resources, destroy eubiosis phenomenon and take place thereupon.Chinese invention patent application: CN1636924, leca and manufacturing process thereof (adopting 73～85% clay);
Chinese patent: CN1344697 (making additive) with 10% clay;
Chinese patent: CN1227207A; CN1440955A; CN1548401; CN1373340A etc.Many patent of invention technology (product) have all taken the clay of different ratios and have made raw material or additive, have lost valuable land resources, are not meet ecology, building materials industry sustainable development direction.
Developing artificial lightweight aggregate industry should be corrected traditional haydite manufacturing and need a large amount of clays that use, and expends the land resources phenomenon that people depend on for existence.Developing novel material and application corresponding technology are made the haydite product innovation, and shape must gone.
Summary of the invention
The purpose of the present patent application is: the new approach of opening up artificial lightweight aggregate new technology, novel material and " turning waste into wealth "; Change with the disease of spraining of making grain with local methods, the direction of catering to China's light-weight aggregate Sustainable development: a kind of Superlight ceramsites and compound method thereof are provided;
The objective of the invention is to utilize the collection mud that becomes silted up in the river course, lake, reservoir of this area to be raw material, being equipped with a certain proportion of shale is auxiliary material, make full use of the heat that the low-melting constituent of the two existence discharges in roasting process, control decarburization temperature, time, optimize and burn the processing condition that expand, produce Superlight ceramsites.
The following compound method of the present invention's utilization realizes;
Compound method: feed proportioning, homogenizing, wet bulb moulding, drying, decarburization, burning expand, method of cooling is formed.
Feed proportioning is made up of raw material, auxiliary material.
Described raw material is the silt collection mud that derives from river course, lake, the reservoir, is sewage, the waste residue of industry and people's daily life discharging, drops into through century-old soil table water transport, drift, and alluvial forms the mud of secondary clay shape, and is thinner than greenery patches sedendary soil.Because proportion cause, comparatively hard sandstone etc. deposit and remove in advance.The silt collection mud of the water-bed sink-float in river course, seem has plasticity-very much, and certain viscosity is arranged.
According to the drift time length of face of land water transport, the area of described silt collection mud distributes different, and what contain irregular Different Weight deal in the collection mud that becomes silted up belongs to the inert fine sand fully.
Become silted up collection mud mineralogical composition according to one's analysis: mainly be feldspar, kaolin, chlorite, montmorillonite, illite, mica and a small amount of organism clay mineral, the percent by weight mean value of the chemical ingredients of the collection mud that becomes silted up is: SiO

2O
38.75%, CaO4.14%, MgO1.11, Na
2O0.42, K
2O1.46, loss on ignition 24.89%.
Described auxiliary material is a shale, is a kind of with illite in particular, and montomorillonite, kaolinite, zeolite are main mud shape shale.
The chemical ingredients percent by weight mean value of shale is: SiO
257.65, Al

2O is a low-melting constituent.The heat that the present invention has utilized the organism (low-melting constituent) in raw material and the auxiliary material to discharge in heat-processed, reduce the fuel usage quantity, shortened and burnt the time of expanding, improved the rate of expansion of haydite when roasting, thereby loss on ignition is big, be weight reduction, improve intensity, the production cost that reduces haydite provides favourable condition.
What accompany irregular Different Weight part in the described silt collection mud belongs to the inert fine sand fully, can not screen.Destroy the plasticity-and the adhesive property of the collection mud that becomes silted up, influenced the wet bulb moulding.The present invention's shale of arranging in pairs or groups is auxiliary material, be the characteristic of utilizing shale inherent adhesive property and fluxing performance, improved the adhesive fastness of mud and fine sand, strengthened the bulk strength after the wet bulb moulding, promote the fusion fast in roasting process of wet bulb spheroid, improved the rate of expansion of haydite.
The processing condition of decarburization are: 300～450 ℃ of temperature, 15～30 minutes time kind.
Burning the processing condition that expand is: 1100～1190 ℃ of temperature, 5～10 minutes time kind.
The product haydite loose volume weight 358～457kg/m of preparation
3, particle unit weight is 745.5kg/m
3, water-intake rate is that 12.4～15.2% density ratings that meet national GB/T17431.1-1998 standard code fully are the index of 400 ultralight coarse aggregate.
The silt collection mud that the present invention adopts originally is to block river course, the harmful waste of influence ecological environment.Because utilization of waste material of the present invention, will be harmful to that mud " is turned waste into wealth " and be the river course mediation, saved expensive mediation effluent charge usefulness; Solved the mediation of original river course and be deposited in the riverbank, taken problem very along a large amount of mud on the limit.Prevented that the mud backflow from causing the pollution once more in river course.The protection land resources that meets national regulation, the relevant policies of guard ring environment pollution.It is the haydite production project of Sustainable development.
The Superlight ceramsites of present method preparation can be used for preparation insulation or the concrete light-weight aggregate of structural thermal insulation, and the light skeletal of lightweight body of wall, lightweight concrete building block also can be used for filler, plastics, the rubber of sewage disposal, the additive of nylon, and its purposes is very extensive.
