Abstract
The invention discloses a test card for the pesticide ultra-low volume oil solution droplet density and size, and belongs to the field of pesticide spraying. The test card comprises a processed substrate and a coating layer with which the substrate is coated. The coating layer is the mixture of an adsorption carrier, a material sensitive to an oil solution and a binding agent and a covering coating. The thickness of the coating layer is 5- 1000 micrometers. The invention further discloses a preparation method of the test card. The test card is convenient to carry, clear in coloring, easy and fast to use, long in storage life, capable of being used indoors and in farming areas, and capable of testing the spray droplet density and size at the same time.
Description
Technical field
The present invention is applied to pesticide spray field, specifically the test card and preparation method thereof of agricultural chemicals ultra-low volume finish droplet density and size.
Background technology
In agricultural production, Agro-chemicals control plant pest is a kind of very effective mode.Accelerating to advance in the process of equipment for plant protection in the last few years; the using method of medicament is more and more diversified; high efficiency, adaptability are good, the advantage such as maneuverability and water-saving saving of labor owing to having for wherein ultra-low volume spray technology (such as aerial pesticide technology and ground level heat smog technology), thus in open country field crop, vegetables in greenhouse booth, the woods, pest control in orchard and the operation such as locust of going out, health dissipation, have played irreplaceable effect.
Agricultural chemicals ultra-low volume finish is the formulation being directly applied for aerial sprays ultra-low volume spray technology and the requirement of thermal aerosol method pesticide application technology, also claims ultra low volume liquids.Ultra-low volume preparation be generally there is certain deliquescent high boiling alkane, high concentration liquid preparation that aromatic hydrocarbons, plant wet goods are main solvent.Therefore, the mensuration of coverage density of droplets is for giving full play to the efficient feature of aerial pesticide and preventing poisoning from having great importance.Ultra-low volume spray droplet is generally atomizing or aerosol (mist droplet particle size is less than 100 μm), and utilizes instrument to carry out measuring often having some limitations.Traditional method of testing, as: magnesium oxide plate has defect that is fragile and that should not preserve for a long time, and dye tracing method need add suitable coloring agent, improves cost and workload, all has the space of improvement.
Also be an important job to the measurement of pesticide spray droplet size in reagent spray process.Utilizing laser diffraction analyzer to carry out accurately measuring is a kind of important method, but not portable, cost is high, the mensuration being unsuitable for field spray uses.
Summary of the invention
The object of the invention is test card providing agricultural chemicals ultra-low volume finish spraying droplet density and size and preparation method thereof, and this test card is the test paper card to agricultural chemicals finish susceptibility, can be applied to indoor and field test spraying droplet density and droplet size.
Test card principle of the present invention utilizes intermiscibility principle, and material coating runs into finish rapid reaction, shows test card background color, thus form coloured droplet vestige with obvious aberration.
The test card of agricultural chemicals ultra-low volume finish droplet density of the present invention and size, comprises, treated substrate and be coated on on-chip coating, and described substrate is the scraps of paper made of fiber or paper card, as all kinds of transfer paper, filter paper and other printing class paper; Described coating is absorption carrier, to the material of finish sensitivity and the potpourri of cementing agent and hide coating, coating thickness 5-1000 μm, described absorption carrier be selected from zeyssatite, potter's clay, white carbon, bentonitic clay, Emathlite, porcelain earth, clay, smectite, mica powder, pyrophillite, attapulgite, vermiculite, perlite, gesso, talcum powder and lime stone one or more; The described material to finish sensitivity be selected from chlorinated paraffin-70, paraffin, Lauxite, vaseline, acryl resin, acryl resin, phenolics, epoxy resin, polystyrene resin, polyvinyl resin, teflon, petroleum sodium sulfonate, vibrin, polyamide one or more.
Further, described cementing agent is selected from one in clay, rosin, gelatin, polyvinyl alcohol (PVA), polymethylmethacrylate, starch or dextrin, sodium carboxymethyl cellulose, furane resin, xanthans and latex and multiple, and described covering coating is the potpourri of titanium dioxide, resin and spreading agent.
A preparation method for the test card of agricultural chemicals ultra-low volume finish droplet density and size, comprises the steps:
(1) substrate is prepared, by being selected from ink, lure in the water-soluble or volatile organic solvent of one or more the dyestuff in red, Congo red, tonyred, solubilised sulphur black, fluorescein, obtain dye liquor, this dye liquor is uniformly coated on the scraps of paper or paper card, makes the substrate catching black background color;
(2) by or volatile organic solvent water-soluble to the material of finish sensitivity, fully dissolve;
