Description
Technical field
The present invention relates to haydite, be specifically related to a kind of Kaolin lightweight through hole haydite.
Background technology
The soil used when cultivating or plant various nursery stock, flowers and plants and vegetable, is to use the earth near on the spot mostly, then adds some plant ash or peat soil is bound together, and the moisture content of these soil is 12～20%, possibly together with substantial amounts of harmful levels of pathogens.
When using these soil incubations or plant various nursery stock, flowers and plants and vegetable, it is difficult to control the water yield of later stage moisturizing, soil moisture content after moisturizing is more than more than 30%, moisture in soil is higher, soil will be in semi-fluid cement paste or muddy, if soil does not has can obtain moisturizing in time, soil it would appear that the lump shape that hardens, all will directly influence the normal growth of plant again.
Along with improving constantly of afforestation project prescription, it is also soilless culture substrate frequently with materials such as lytag, leca, haydites of book structure and flower ceramsites.
Lytag, leca and haydites of book structure are a kind of artificial lightweight aggregates, using high-quality clay, shale or flyash is primary raw material, by rotary kiln high-temperature roasting, form through expanded, due to inside it in alveolate texture, thus there is the features such as lightweight, high-strength, heat conductivity is low, water absorption rate is little, (refer to national standard: GBT17431.1-2010
Light-weight aggregate and test method thereof).
Owing to artificial lightweight aggregate is after high-temperature roasting, its surface forms one layer of enamel, although micropore in alveolate texture inside artificial lightweight aggregate, but, the micropore of internal cellular shape structure is a kind of closed pore, the micropore of alveolate texture does not connects, and and external environment, water absorption rate is relatively low, moisture it is practically free of inside artificial lightweight aggregate, artificial lightweight aggregate is put in water body, the surface of water can only be floated on, therefore, artificial lightweight aggregate can only be sprinkling upon the top layer of soil, decorate as one, plantation each seedling wood can not be directly used in, the plant such as flowers and vegetable.
Chinese patent Authorization Notice No.: CN 102503539 B, authorized announcement date: on 04 17th, 2013, entitled " spherical attapulgite flower ceramsite ", disclose that " a kind of spherical attapulgite flower ceramsite, spherical attapulgite flower ceramsite is glued attapulgite clay powder, attapulgite clay mine tailing, red bentonite in powder, mud, kieselguhr mine tailing and powdered rice hulls by height and forms.By the dispensing of spherical attapulgite flower ceramsite through mixing, pelletize, roasting, cool down and screening is packaged as spherical attapulgite flower ceramsite ".
Spheroidal ceramsite preparation process: in granulation process; first powdery dispensing is processed into a kind of bead being less than 0.5 millimeter; then the spray water solution that will prepare; spray the bead surface in on-stream comminutor; again powdery dispensing is trickled down on the surface of moistening bead; through repeated sprinkling spray water solution and powdery dispensing is trickled down on the surface of moistening bead; parcel through layer upon layer; the volume of bead constantly increases; it is finally completed the overall process of pelletize, is prepared as the spheroidal haydite that a kind of strength ratio is higher.
Spheroidal haydite internal structure after roasting is tightr, although spheroidal haydite strength ratio is higher, but it is little to cause effective ratio area, and proportion and bulk density are the biggest, thus reduces absorbability and the water absorption rate of spheroidal haydite.
Spherical attapulgite flower ceramsite is a kind of spheroidal haydite, and in roasting process, internal being difficult to of spherical attapulgite flower ceramsite can be grilled thoroughly completely, directly influences the inherent quality of spherical attapulgite flower ceramsite.
Test through multiple sampling: the artificial lightweight aggregate average bulk density >=800kg/m sold on market, mean water absorption rate≤18%, normal soil average bulk density >=1020kg/m, mean water absorption rate≤26%, spherical attapulgite flower ceramsite average bulk density >=850kg/m, mean water absorption rate≤50%.
By contrast, the bulk density of these several haydites is the biggest, and water absorption rate is smaller, and user wishes to invent a kind of bulk density≤800kg/m, and the light ceramic of water absorption rate >=65%, to be applicable to prepare soilless culture substrate and Nutrition Soil.
