Abstract
The present invention provides a mineral pesticide carrier which is developed by adopting PAL material, possesses natural mesoporosity and richly contains several micro elements of iodine, selenium and zinc, etc. Besides, it also has the special physical property, adsorbability, suspension property and control release property.
Description
Technical field
(its raw material is a palygorskite to the present invention relates to a kind of PAL of utilization material, through the ultramicronising purification processes, palygorskite purity＞90%, particle diameter＜8 μ) makes the method for farm chemical carrier through specially treated, main technique is ultramicronising processing, activation processing, reaming processing, and the specific surface area of PAL material is increased, and pore volume increases, adsorptivity improves, and can be used for farm chemical carrier.
Background technology
Use the purpose of farm chemical carrier to be to reduce pesticide dosage, reduce and alleviate toxicity of pesticide, have good environment protecting.The characteristics of the adsorptivity of PAL material, slow release, suspension, good dispersion are as farm chemical carrier tool advantage.
Summary of the invention
Main purpose of the present invention:
1, at the characteristic resources PAL material in Gansu Province (account for world saving 80%), the layer intrinsic with this material, chain, the microtexture of fibrous crystalline structure and nanoscale hole passage, reach bigger specific surface area of tool and special Surface Physical Chemistry structure and ionic condition, be rich in iodine with this material is distinctive, selenium, zinc is the beneficial element of the needed by human body of representative, pass through technological means, the PAL material is carried out ultramicronising to be handled, the fine pore structure of the passage of its crystals and set is through soda acid concerted catalysis reaction, and the shape selective catalysis dead angle with molecular sieve.Control sour solvent strength, obtain the best ion exchange capacity, cation is separated out, cause the microcosmic octahedron, interior hole increases, and microscopic voids increases, and surface-active increases.
2, to PAL material, use the on-mechanical counter-boring techniques, handle again through technical finesse, this counter-boring techniques is after utilizing the gelation of on-mechanical expanding agent, occupy the space, through thermal treatment, after volatilization or the transpiration, produce the hole of all size, macropore, mesopore, the micropore quantity of the PAL material of void structure growth are more increased, and particularly micropore quantity increases, and has expanded surface area greatly, strengthened adsorption function, and do not had any chemical contamination.
Embodiment
Technical matters divided for two steps implemented
1, pulverizing post mill → gas jigs branch → PAL powder body material (200 order) to raw ore through (purity 60%＞) is purified in sorting.
2, processing technology as shown in drawings.
Description of drawings: accompanying drawing is processing process figure.
Claims (4)
1, a kind of novel agrochemical carrier-PAL material (its raw material is a palygorskite, through the ultramicronising purification processes, palygorskite purity＞90%, particle diameter＜8 μ) farm chemical carrier.Important indicator as farm chemical carrier has: chemical composition, adsorptivity, slow release, suspension, dispersiveness.The PAL material all is suitable for as the index of carrier.The PAL material can spray after purifying and the ultramicronising processing, reaching micron order.The present invention first with the PAL material as farm chemical carrier.
2, the PAL powder body material is handled through activating process, it is characterized in that adding the PAL powder in the solution of acid and water preparation in following ratio, PAL powder body material: 8% dilute acid solutions=1: 1.2, after soaking 24 hours, be heated to 95 ℃, keep constant temperature, stir 1.5h, behind the filtering excessive moisture,, pulverize stand-by 135 ℃ of oven dry processing down.
3, according to claim 1, the PAL material of handling carries out solute gelation reaming, uses the expanding agent saturated solution, but be the granulation shape with the powder stirring, carry out granulation, after the drying baking is burnt under 350 ℃ of temperature, wash with water, filtering moisture content, oven dry, pulverize carrier material.
4, the PAL material is the natural inorganic material, environmentally safe, tool environment-friendly function.
