product details

  一、 Basic features of products

  Sp-of3472b is a kind of new polymer surfactant with comb structure formed by the copolymerization of unsaturated monomers. It is an excellent surfactant for environmental protection pesticide preparation oil suspension concentrate (OD). The good solvated side chain maintains the compatibility between the dispersed particles and the continuous phase, and the higher charge density of the side chain increases the multi-point adsorption capacity of the particle surface; It should be used together with sp-of3462 emulsifier to effectively improve the grinding efficiency, reduce the particle size and improve the stability of the preparation.

  二、 Typical data

  Appearance: yellow viscous liquid

  PH value (1% aqueous solution, 25 ℃): 3.5

  Pour point: 26.5 ℃

  Nonvolatile (%): 99.5

  Moisture (%): 0.15

  Solubility: dispersed in water, soluble in methyl oleate, soybean oil and other vegetable oils, but insoluble in mineral oil.

  三、 Application examples

Name of preparationSp-of3472b add 2%No sp-of3472b
15% mesotrione ODAfter grinding for one hour, D90 = 7.7 μ m, and there was no significant change in thermal storage for 14 days.After grinding for one hour, D90 = 15.6 μ m, and 14 days of thermal storage, there was sediment at the bottom.
25% thiamethoxam ODAfter grinding for one hour, D90 = 4.1 μ m, and there was no significant change in thermal storage for 14 days.After grinding for one hour, D90 is 13.8 μ m, and the oil separation is more than 10% after 14 days of thermal storage.
20% furamethoxam ODAfter grinding for one hour, D90 = 3.2 μ m, and there was no significant change in thermal storage for 14 days.After grinding for one hour, D90 = 9.8 μ m, and the oil precipitation is more than 10% after 14 days of thermal storage.
3% Nicosulfuron methyl + 8% mesotrione + 24% atrazine ODAfter storage at room temperature for one year, the oil separation rate of the sample is 5%, and the bottom sediment is about 4%After one year storage at room temperature, the oil separation rate is 15%, and the bottom viscous substance is about 10%.
4% Nicosulfuron methyl + 20 atrazine ODAfter storage at room temperature for one year, the oil separation rate of the sample is 3%, the bottom sediment is about 2%, and the viscosity of the system has no obvious change.After one year storage at room temperature, the oil separation rate of the sample is 10%, the bottom sediment is about 6%, and the lower part of the sample is thickened.
