Pesticide Auxiliary Concept: Any substance that is mixed with the original drug or mixed with the original drug through the processing process to improve the physical and chemical properties of the preparation, improve the efficacy and ease of use, is collectively referred to as a pesticide adjuvant, referred to as a pesticide adjuvant. Generally speaking, the pesticide adjuvant itself is not biologically active, but the use of the adjuvant is appropriate or not, which has a great influence on the efficacy of the pesticide preparation. For example, a blended emulsifiable concentrate containing 10% propanil and 30% diesel has a similar herbicidal effect as a 20% enemy emulsifiable concentrate without diesel fuel, while the amount of enemy scorpion is 1 times different; when using Bordeaux mixture, if it is added 0.2%~0.3% bone glue, which is resistant to rain and can improve the disease prevention effect.
The rational use of pesticide additives can often improve the safety of the pesticides on plants and reduce the toxicity to humans and animals. Filler: The filler can be used to dilute the original pesticide, reduce the amount of the original drug, make the original drug easy to mechanically pulverize, and increase the dispersibility of the original drug. It is a filler for making powder or wettable powder, such as clay, clay, kaolin, diatom. Soil, pyrophyllite, talcum powder, etc.
Wet spread agent: Wet spread agent refers to an auxiliary agent that can reduce the surface tension of water and make water easy to wet the solid surface. When the liquid is sprayed onto the surface of the drug, it is easy to spread on the surface of the drug to improve the control effect. Such as tea dry, pulp waste, washing powder, pull powder and so on.
Emulsifier: An additive that makes an otherwise incompatible two-phase liquid (such as oil and water) an opaque or translucent emulsifiable concentrate, called an emulsifier. Such as Turkish red oil, diglycerin sodium laurate, castor oil polyoxyethyl ether, alkyl phenyl polyethyl ether and so on.
Dispersing agents: divided into two types. The utility model relates to a pesticide stock liquid dispersing agent, which is a substance with high viscosity property, which can disperse molten pesticide into colloidal granules, such as waste sticky honey concentrate and pulp waste liquid concentrate, by mechanical action; The dispersing agent of the pesticide preparation can prevent the powder from flocculation, so that the powdered pesticide can be well dispersed when being sprayed.
Adhesive: Adhesive refers to an additive that increases the adhesion of a pesticide to a solid surface. After the adhesion of the drug is improved, it can withstand the scouring of rainwater and improve the residual effect of the pesticide. Usually, a proper amount of mineral oil with a relatively large viscosity is added to the powder, and an appropriate amount of starch paste and gelatin are added to the liquid pesticide.
Stabilizer: Stabilizer, also known as anticoagulant, prevents the physical properties of pesticide formulations (wettable powders) from deteriorating during storage (suspension reduction).
Decontaminant: An auxiliaries that prevent decomposition of the active ingredients of a pesticide formulation during storage. Some include anti-deposition agents in the class of stabilizers. For example, the addition of a decontaminant to some emulsions can improve the stability of the emulsion.
Synergist: It has no insecticidal or bactericidal effect, but it can improve the insecticide and bactericidal effect of the original drug.
Solvent: Solvent refers to an additive that can dissolve the original pesticide, and is mostly used to process emulsifiable pesticides. Such as benzene, xylene and the like.
PVC High Speed Door are designed for indoor use and ensure rapid handling operations between different areas that should remain separated. These safe and efficient industrial doors are made of a shaped steel frame and covered with PVC. These high speed doors are safe and efficient and consist of a shaped steel frame covered with PVC. Safety is ensured by their photocells and barriers.
High speed doors protect us from harm, save energy and help us to separate processes for optimal productivity. A High Speed Door's most important job is to simply open and close quickly and safely every time you need it.
The high speed pvc roll shutter door require high strains, caused by the high operating speed and the frequency of openings, have to be taken into account during construction. In the same way, basic conditions like size and installation location add up to considerable requirements regarding safety and control technique.
