Embodiment 1

[0020] For the specific experimental process and method of the present invention, refer to the test method of the United Nations "NY / T1860.16-2010 Pesticide Physicochemical Properties Determination Test Guideline Part 16: Corrosivity to Packaging Samples" test method, and according to the test method of the liquid pesticide within 14 days on the packaging The corrosion rate is tested for liquid corrosiveness. The liquid pesticide is 30% (weight) propineb suspension concentrate.

[0021] in such as figure 1 On the device shown, two fully transparent glass container kettles with scales are placed in a constant temperature water bath and fixed on the iron stand, and two serpentine condensers are also fixed on the iron stand and connected to the container kettle. The water inlet and outlet of the condensation pipe are connected with a tee with a rubber tube and connected with a circulating cooling water bath. The controller of the fully automatic liquid replenishment controller ...

Abstract

The invention relates to a device for testing corrosion of a liquid pesticide to a package, and mainly solves the problem of inaccurate test results caused by reduction of to-be-test sample amount in a corrosion container kettle along with the test time in the prior art. The device for testing the corrosion of the liquid pesticide to the package mainly includes a thermostatic bath 5, a corrosion container kettle 3, an automatic fluid infusion controller 10, a condensing tube 8, a circulating cooling medium control system 1, a thermostatic bath temperature controller 6, an electromagnetic valve 9, a pump 7, a horizontal floater 4 and a package sample 2; an inlet and an outlet of a cooling medium in the condensing tube 8 are connected with the circulating cooling medium control system 1, the automatic fluid infusion controller 10 is connected with the horizontal floater 4 in the corrosion container kettle 3, the electromagnetic valve 9 is respectively connected with the automatic fluid infusion controller 10 and the pump 7, and the technical scheme well solve the problem of inaccurate test results, and the device can be used for testing the corrosion of the liquid pesticide to the package.

Description

technical field [0001] The invention relates to a device for testing the corrosivity of liquid pesticides to packaging. Background technique [0002] Corrosion tests of liquid pesticides to packaging materials are generally based on "NY / T1860.16-2010 Guidelines for the Determination of Physical and Chemical Properties of Pesticides, Part 16: Corrosivity to Packaging Samples" (hereinafter referred to as "NY / T1860.16-2010 "), the test device in "NY / T1860.16-2010" is a special device used to evaluate the corrosivity of liquid pesticides to packaging materials. [0003] There are also some experimental devices for testing the corrosion resistance of packaging materials, such as CN201210592965.5 providing a kind of electrolytic cell for detecting the corrosion resistance of packaging materials. The metal packaging sample is a sealed electrolytic cell at the bottom. There is electrolyte in the electrolytic cell. The electrolytic cell also has a base composed of upper and lower gl...
