Description
Technical field
The present invention relates to a kind of foaming microporosity glass pumice, relate in particular to a kind of improving the soil with foaming microporosity glass pumice and preparation method thereof.
Technical background
At present behind the soil plant of plantation for some time, owing to use the effect of fertilizer, the soil hardening of hardening easily, the ventilation property of soil is just poor, is unfavorable for plant to the absorption of moisture content, if soil is too loose simultaneously, growing of disease and pest is arranged easily again.
Summary of the invention
The object of the present invention is to provide a kind of usefulness foaming microporosity glass pumice of improving the soil that grows that can improve soil compaction, increase soil permeability ventilation property and minimizing disease and pest.
Technology contents of the present invention is, a kind of improving the soil with foaming microporosity glass pumice is characterized in that it contains the foaming microporosity, and foaming aperture, microporosity is 2～3mm, and water-intake rate is 30～50%, and intensity is 2～4MPa, and density is 0.2～0.3g/cm
3It is made behind sintering by foaming mixtures, and foaming mixtures comprises the component of following weight percent:
Glass powder: 85～90
Marble flour: 3～8
Silica powder: 2～5
Terra alba: 2～5
Wherein the fineness of glass powder is 40～100 μ m, and the fineness of marble flour is 20～40 μ m, and the fineness of silica powder is 20～40 μ m; The terra alba fineness is 20～40 μ m.
Be the sintering process of preparation glass pumice at the above-mentioned sintering process that adopts in improving the soil with foaming microporosity glass pumice that disappears, be specially: foaming mixtures is stacked in the process furnace, foaming mixtures in process furnace through preheating, for the first time heat up heating, sintering heating, heat up and make sintered and foamed heating thing after heating and the foaming heating for the second time, naturally cool to the room temperature glass pumice that gets product after sintered and foamed heating thing is taken out from process furnace.
Silica and terra alba acting in conjunction in the foaming mixtures among the present invention, the viscosity of increase molten glass makes product air vent aperture larger amt more, and is separated foam when effectively increasing foaming; Finished product be broken into than after the small particle size with mixing with soil, can effectively improve soil compaction thus, increase the soil permeability ventilation property, and utilize the alkalescence of glass itself can effectively reduce growing of disease and pest.
Can use discarded glass above-mentioned improving the soil with the glass powder in the bubble mixt of foaming microporosity glass pumice sintering, can reduce production costs greatly thus, also recycle resource simultaneously.
Another object of the present invention is to provide above-mentioned a kind of improving the soil with the preparation method of foaming microporosity glass pumice.
A kind of improving the soil with the preparation method of foaming microporosity glass pumice the steps include:
(1), earlier with the mixed foaming mixtures that gets of the component of following weight percent:
Glass powder: 85～90
Marble flour: 3～8
Silica powder: 2～5
Terra alba: 2～5
Wherein the fineness of glass powder is 40～100 μ m, and the fineness of marble flour is 20～40 μ m, and the fineness of silica powder is 20～40 μ m; The terra alba fineness is 20～40 μ m;
(2), the above-mentioned foaming mixtures that makes is stacked in the process furnace, foaming mixtures in process furnace through preheating, for the first time heat up heating, sintering heating, heat up and make sintered and foamed heating thing after heating and the foaming heating for the second time, naturally cool to room temperature after sintered and foamed heating thing is taken out and namely get and improve the soil with the microporosity glass pumice that foams from process furnace; Wherein preheating temperature is 350～450 ℃, and be 5～20 minutes warm up time; The Heating temperature that heats up for the first time is 680～720 ℃, and be 10～30 minutes heat-up time; Burning till Heating temperature is 730～770 ℃, and be 5～15 minutes heat-up time; The Heating temperature that heats up for the second time is 780～820 ℃, and be 10～30 minutes heat-up time; The foaming Heating temperature is 950～1010 ℃, and be 5～10 minutes heat-up time.
The advantage that the present invention has is: silica and terra alba acting in conjunction in the foaming mixtures, increase the viscosity of molten glass when effectively increasing foaming, and make product air vent aperture larger amt more, and be separated foam, and have higher water-intake rate is arranged; Finished product be broken into than after the small particle size with mixing with soil, can effectively improve soil compaction thus, increase the soil permeability ventilation property, can play certain retaining effect simultaneously, and utilize the alkalescence of glass itself can effectively reduce growing of disease and pest; It is glass that finished product is produced main raw material, especially can utilize discarded glass, and its production use cost is just lower.
