2 recipe determination
The selection of 2.1 wetting dispersing agents
The suspension system of pesticide suspension concentrate comes from a kind of thermodynamic instability between colloidal dispersion system and coarse dispersion
System.The particle diameter of aqueous suspension agent typically has several microns of sizes, and due to particle diameter very little, the surface free energy of particle is very big, particle
Between easy adsorption-condensation.In order to increase the stability of aqueous suspension agent, generally a certain amount of wetting dispersing agent must be added, in dispersion phase grain
Form firm diaphragm around son, or form electric double layer, make pesticide granules surface powered, between charged particle mutually exclusive and
So that dispersion is tended towards stability, be allowed in storage process not condense and tie bottom phenomenon.Even if having a small amount of layering, through kicking the beam
Jog is dynamic can still to become stable suspension system, and with good in dispersiveness.
According to the research experience of the physical and chemical performance and its similar products of alphamethrin and indoxacarb processing, we select
Different wetting dispersing agents is screened (table 1)
1 wetting dispersing agent Selection experiment of table（Unit:%）
The selection of 2.2 thickeners
The viscosity of suspending agent is a key factor for affecting product bin stability.Viscosity is too little, and product places a period of time
Easily it is layered afterwards, easily lumps；Viscosity is too big, and it is serious that product is difficult to topple over wall built-up, to processing and using bringing difficulty.In order to improve product
The pourability of product, improves suspensibility and bin stability, product must be made to have a suitable viscosity.For this purpose, according to exploitation in the past
The experience of suspending agent, on the basis of 6# formula, we screen several thickeners and have carried out stability test, find to select xanthan
Preferably, which the results are shown in Table 2 to glue thickener effect.Knowable to the selection result, with preparation dewatering ability when xanthans (0.15%)
While preferably, formulation flows are preferable, therefore finally determine xanthans as 25% alphamethrin. the thickening of indoxacarb SC
Agent, its consumption are 0.15%.
2 thickener Selection experiment of table
The selection of 2.3 antifreezing agents
Pesticide suspension concentrate with water as medium, its formula will not only be suitable for storing under the conditions of southern high-temperature and use, and
And to also be suitable for northern area cold under storage and use.The former can add antifreezing agent less, and the latter must add in right amount
Antifreezing agent, to ensure normal using effect.We have been contrast test, San Zheyong to conventional ethylene glycol, glycerine, urea
It is 5.0% that amount is even.When test finds to make antifreezing agent with glycerine and urea, although during cold storage, aqueous suspension agent outward appearance is unchanged,
Mobility is decreased obviously, and ethylene glycol does not have such case.Therefore, this formulation selection ethylene glycol is used as antifreezing agent, its consumption
For 5.0%.
The selection of 2.4 defoamers
Wet multi-stage sand milling superfine grinding being adopted the production technology of agricultural chemicals suspension agent, the dispersion impeller of high-speed rotation is substantial amounts of sky more
Gas is brought into and is dispersed into atomic little bubble, makes suspending agent rapid spatial expansion.These micro-bubbles can not only affect viscosity (stream
Dynamic property is deteriorated), measure and pack, and will significantly reduce production efficiency.If being unable to froth breaking, this becomes may creeping type
Dilatant fluid.So, a certain amount of defoamer is added in pharmaceutical formulation, and requires that defoamer must be able to each group of same preparation
Dividing has good intermiscibility.This formula organic silicon defoamer AF-9903, is characterized in each group that defoaming effect is good, with preparation
Split-phase dissolubility is good, and consumption is few, dosage 0.3%, and price is low.
