How can pesticides fail? How to remedy pesticides? Next, we will introduce you to the causes and solutions of pesticide failures in detail, helping you to better use pesticides.
Cloud causes and solutions for pesticide failure:
Objective factors such as temperature, humidity, rain, light, wind, soil properties and other environmental factors directly affect the physiological activities of pests and diseases and the performance of pesticides, the results will affect the efficacy of pesticides.
The chemical composition, physical and chemical properties, mechanism of action, dosage and processing properties of pesticides may directly or indirectly affect the efficacy of the pesticide.
What should I do with the failed pesticide?
1, powder powder
If the moisture absorption is agglomerated during storage, it needs to be placed in a cool and ventilated place to dry, and can be used after being crushed. If the agglomeration is serious, it can only be used for toxic soil.
2, wettable powder
1 Take 1 part of wettable powder, add 200 parts of water, hold in a glass cup, shake for a certain period of time, observe the suspension, if the precipitation of the drug is slow, it means that the suspension is good;
2 In case of poor quality, silicone additives or 0.1% neutral detergent should be added before use to increase the wet spread. If the wettable powder absorbs moisture and is hard, it should not be used as a spray.
3, emulsifiable
1 changes in the emulsifying properties of the cream. Take 1 part of emulsifiable concentrate, add 200 parts of water, put it in a glass cup, shake it and let it stand for about half an hour. Observe the emulsification. If there is no oil slick in the upper layer, there is no precipitation in the lower layer, and there is no obvious oil bead in the middle, indicating that the emulsification performance is good. If there is emulsifiable concentrate, there is sedimentation, and there is stratification after 10 minutes, indicating that the emulsion is destroyed and cannot be used; 2 agglomeration. If the emulsified concentrate has a non-flowing viscous liquid or has formed a soapy solid, it proves that the solvent has been mostly volatilized and the quality has changed and cannot be used;
3 precipitation crystallization phenomenon. For long-term storage of the emulsion, there will be white crystals on the bottom of the bottle or turbidity. If the emulsified milk bottle is immersed in warm water of 30 ° C ~ 40 ° C, the crystallization can be dissolved in about 30 minutes, and it will return to a transparent liquid, indicating that the quality is still good and can be used. If it does not dissolve, it indicates that the quality of the cream has changed and cannot be used.
Custom Stainless Steel Open End Blind Rivets, made of stainless steel and aluminum, also rivets can be manufactured with standard steel, copper and brass. We can also add various surface treatments and customize sizing to suit clients' specific applications. These rivets utilize a built-in plastic cap to provide waterproof fastening. They also help to prevent corrosion during the working.
Open end blind rivets, also known as pop rivets, are a type of fastener used to join two or more materials together. They consist of a rivet body and a mandrel, which is a thin rod that extends through the center of the rivet.
The rivet body has a hollow cylindrical shape with a slightly larger diameter than the mandrel. The mandrel is inserted into the rivet body and protrudes from one end.
To install an open end blind rivet, a rivet gun is used. The rivet is placed through pre-drilled holes in the materials to be joined, and the gun is used to pull the mandrel through the rivet body. As the mandrel is pulled, it deforms the rivet body, creating a bulge on the blind side of the materials. This bulge creates a secure joint between the materials.
Open end blind rivets are commonly used in applications where access to the blind side of the materials is limited or impossible. They are widely used in industries such as automotive, aerospace, construction, and manufacturing. They offer a fast and efficient method of joining materials, and can be easily installed with basic hand tools.
