Morwet series of dispersant and wetting agent to their original drug of a variety of active ingredients and formulation stability of the general known, which Morwet D-425 and Morwet EFW as a standard of naphthalene sulfonate (condensation) class of dispersants and wetting agents are domestic and foreign R & D personnel in pesticide formulations as the preferred test, the first such product is the world's developed for pesticide products, the introduction of three decades of time, the application of methods and techniques have been patented for many researchers.
1. Morwet D-425 dispersant application of dispersant Morwet
D-425 as sodium alkyl naphthalene sulfonic acid condensation, the active ingredient is greater than 88%, PH value of 7.5-10.0, for WP, SC and WDG. In WP the lowest addition level of 2-3%, in the WDG the lowest addition level of 3-5%, the lowest in the SC in the 2-2.5% addition level. dispersant dosage is Akzo Nobel in Fort Worth, Texas, after a lot of powder lab test recommended, due to the variety and quality of the original drug differences, domestic use, depending on the circumstances, the addition of dispersant to be increased, such as the amine in 80% WP in killing snails, Morwet D-425 of the addition of 7 % or so. In WDG, the granulation process will affect the actual needs of dispersant concentration, the higher density component granulation, we need to focus more on particle dispersion and disintegration properties and then add more dispersant, such as imidacloprid 75% WDG, the fluidized bed granulation addition of 6.5%, while 7.5% required extrusion granulation. In SC, the solid concentration is high, the need to add the D-425 volume increased to 3-5%. surface active agent formulation dosage of the composition of the final formulation should be proportional to the solid particles are added to the surface area. If the average size of solid particles smaller the greater the surface area, so you need to add more many surfactants.
Morwet D-425 alkaline, unstable under alkaline conditions for pesticide formulations to be adjusted pH, such as carbaryl 90% WDG in the amount of citric acid must be added to adjust the PH value of the preparations.
Morwet D-425 with other types of dispersing agent used in conjunction with, such as lignin dispersants. the country has the WP formulation, if the suspension and dispersion is not satisfactory, the original based on the formula by adding 0.5-2% of the Morwet D-425, there will be significant improvement in performance. Also in the WDG and the lignin can also be used in conjunction with dispersing agents, such as a foreign patents: Morwet D-425 the amount of 2.25 % sodium lignosulfonate 6.5%, Morwet EFW 2.25%, 11% sodium sulfate, the original drug and kaolin formula for mancozeb and other products. In SC,, Morwet D-425 can be used in conjunction with the emulsifier , add the volume of 0.5-1%, to reduce viscosity and improve grinding efficiency, enhance the storage period of preparation stability.
2. Morwet EFW application of wetting agent wetting agent Morwet EFW
is alkyl naphthalene sulfonate salt and a mixture of anionic wetting agents, more than 95% active ingredient, is Morwet series wettability, permeability best products, is characterized by fast wetting, helping the collapse of particles. the product higher than strong wetting to easily absorb moisture in the air, to be kept sealed in a dry place. wetting agent Morwet EFW for WP, SC and WDG, the addition level in the 1-2% WP, WDG in the 2-3% addition level, the addition level in the 1-2% of SC. WDG appropriate increase in the amount of EFW, help to improve the disintegration of the particles in the formulation experiments, such as the effect of the particle does not collapse Well, the amount of EFW can be increased to 6%, such as Bacillus thuringiensis strains in 80% WDG.
