3.1 Aerosols insecticide

A product that seal and fill active constituents, solvents and auxiliaries in an aerosol packaging container, and uses the pressure of the propellant to eject the contents through a valve and an actuator in a predetermined form, so as to kill injurious insects.

4.1 General

Requirements for use of active constituents, toxicology, active constituent content and allowable fluctuation range, pesticide effect, heat storage stability, aerosols insecticide methanol content, aerosols insecticide internal pressure, aerosols insecticide net content shall comply with the provisions of GB 24330.

4.2 Appearance and senses

4.3 Spray rate

4.3.1 The product shall be foggy after spraying.

4.3.2 Spray rate >= 98.0%. […]

4.4 Acidity

4.4.1 Oil-based products (calculated as HCl) <= 0.02% (mass fraction).

4.4.2 The pH range of water-based and alcohol-based products is 4.0 ~ 8.0.

5.1 General

Requirements for use of active constituents, toxicology, active constituent content and allowable fluctuation range, pesticide effect, heat storage stability, aerosols insecticide methanol content, aerosols insecticide internal pressure, aerosols insecticide net content shall be tested according to the provisions of GB 24330.

5.2 Appearance and senses

5.3 Spray rate

5.3.1 Instruments

5.3.1.1 Constant temperature water bath. temperature control accuracy of ±2 °C.

5.4 Acidity

5.4.1 Acidity test (oil-based products)

5.4.1.1 Reagent

5.4.1.1.1 Standard titration solution of potassium hydroxide. c(KOH) = 0.02 mol/L, prepare and calibrate according to GB/T 601.

5.4.1.1.2 Neutral ethanol. take 95% analytically pure ethanol; add a few drops of phenolphthalein indicator solution; use potassium hydroxide standard titration solution (5.4.1.1.1) to titrate, until reddish color appears.

5.4.1.3 Calculation of results

Calculate the acidity of the sample according to Formula (2).

5.4.2 pH measurement (water-based, alcohol-based products)

Shake the sample; use a nozzle with a catheter to slowly spray the appropriate amount of insecticide into the test tube; put it in a 55 °C water bath; after the propellant is slowly exhausted (until there are no obvious bubbles), perform the test according to the method of GB/T 1601.

5.5 Moisture

Take the sample after pretreatment, according to the Karl Fischer method in GB/T 1600-2001 (it is allowed to use a trace moisture analyzer of the same accuracy).
