Abstract
The invention discloses a kind of sylvite ore mine tailing lightweight through hole haydite, its technical scheme is characterized by, and sylvite ore mine tailing lightweight through hole haydite is made up of sylvite ore mine tailing, high viscous attapulgite clay, powdery attapulgite foaming agent, active white clay waste slag, cenosphere, expanded perlite, expanded vermiculite, precipitated calcium carbonate and ferrous sulfate.Dispensing is stirred mixing, extruder grain, drying, roasting, be incubated, sieve after pack as sylvite ore mine tailing lightweight through hole haydite.The feature that sylvite ore mine tailing lightweight through hole haydite has that specific surface area is big, bulk density is little, water absorption rate is high, permeability is superior, appearance and modeling free from extraneous odour attractive in appearance, lightweight intensity are good, micropore and macropore are integrated.During for cultivating or plant various nursery stock, flowers and plants and vegetable, the root of plant will absorb water or the nutritional labeling of liquid fertilizer from sylvite ore mine tailing lightweight through hole haydite, guaranteeing that growth and development of plants is good, survival rate is high and the life-span is longer, it is adaptable to preparation soilless culture substrate and Nutrition Soil.
Description
Technical field
The present invention relates to haydite, be specifically related to a kind of sylvite ore mine tailing 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
Adding some plant ash or peat soil is bound together, the moisture content of these soil, 12～20%, has possibly together with substantial amounts of
Fall ill bacterium.
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, mends
Soil moisture content after water is more than more than 30%, and the moisture in soil is higher, and soil will be in semi-fluid cement paste or mud
Pulpous state, if soil does not has can obtain moisturizing in time, soil it would appear that the lump shape that hardens, all will directly influence and plant again
The normal growth of thing.
Along with improving constantly of afforestation project prescription, also frequently with lytag, leca, haydites of book structure and
The materials such as flower ceramsite are soilless culture substrate.
Lytag, leca and haydites of book structure are a kind of artificial lightweight aggregates, use high-quality clay, shale or snake
Stone is primary raw material, by rotary kiln high-temperature roasting, forms through expanded, due to inside it in alveolate texture, thus have light
The features such as matter, high-strength, heat conductivity is low, water absorption rate is little, (refer to national standard: GBT17431.1-2010 light-weight aggregate and examination thereof
Proved recipe method).
Owing to artificial lightweight aggregate is after high-temperature roasting, its surface formed one layer of enamel, although inside artificial lightweight aggregate in
The micropore of alveolate texture, but, the micropore of internal cellular shape structure is a kind of closed pore, the micropore of alveolate texture not only that
Do not connect between this, and and external environment, water absorption rate is relatively low, is practically free of moisture inside artificial lightweight aggregate, by artificial
Light-weight aggregate is put in water body, can only float on the surface of water, and therefore, artificial lightweight aggregate can only be sprinkling upon the top layer of soil, as one
Plant decoration, the plants such as the various nursery stocks of plantation, flowers and vegetable can not be directly used in.

Viscous attapulgite clay powder, attapulgite clay mine tailing, red bentonite in powder, mud, calcium carbonate slag mine tailing and powdered rice hulls
Composition.By the dispensing of spherical attapulgite flower ceramsite through mixing, pelletize, roasting, cool down and screening to be packaged as spheroidal recessed
Convex rod flower ceramsite ".
Spheroidal ceramsite preparation process: in granulation process, is first processed into powdery dispensing and a kind of is less than 0.5 millimeter little
Ball, the spray water solution that then will prepare, sprays the bead surface in on-stream comminutor, then powdery dispensing is trickled down
On the surface of moistening bead, through repeated sprinkling spray water solution and powdery dispensing is trickled down at moistening bead
Surface, through the parcel of layer upon layer, the volume of bead constantly increases, and is finally completed the overall process of pelletize, is prepared as one
The spheroidal haydite that strength ratio is higher.
Spheroidal haydite internal structure after roasting is tightr, although spheroidal haydite strength ratio is higher, but
Causing effective ratio area little, proportion and bulk density are the biggest, thus reduce spheroidal haydite absorbability and
Water absorption rate.
Spherical attapulgite flower ceramsite is a kind of spheroidal haydite, and in roasting process, spherical attapulgite flower is made pottery
Intragranular portion is difficult to grill 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 is made pottery
Grain 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 invention one
Bulk density≤800kg/m, the light ceramic of water absorption rate >=65%, to be applicable to prepare soilless culture substrate and Nutrition Soil.
Mineral Resources in China 80% is intergrowth mineral, and a large amount of valuable resources retain among mine tailing, and tailings impoundment needs
Taking a large amount of soil, a lot of Tailings Dams exceed the time limit or over loading uses, even violation operation, make Tailings Dam there is safety greatly hidden
Suffering from, people's property and life security to surrounding area cause serious threat.
