Embodiment Construction

[0014] Such as figure 1 As shown, the metal corrosion test device of the present invention includes two fully transparent scaled corrosion container kettles 1, two sets of serpentine condenser tubes 2, a constant temperature water bath 3, a circulating cooling water bath 4, and fully automatic liquid level control The device, analytical balance and iron stand, can carry out two sets of tests at the same time. Among them, the fully transparent scale corrosion container kettle, the serpentine condenser are custom-made, the constant temperature water bath, the circulating cooling water bath, the automatic liquid level control device, and the analytical balance is outsourced.

[0015] Two fully transparent scale corrosion container kettles 1 are placed in the constant temperature water bath 3 and fixed on the iron stand, and the two serpentine condenser tubes 2 are also fixed on the iron stand and connected to the two container kettles 1 respectively. The water inlet and outlet o...

Abstract

The invention provides a liquid-to-metal corrosion testing device, which comprises two fully transparent corrosion container kettles with scales, two sets of S-shaped condensation pipes, a thermostatic water bath, a circulating cooling water bath, a full-automatic liquid level control device, an analytical balance and an iron support, wherein the transparent corrosion container kettles are semi-submerged in the thermostatic water bath at the constant temperature of 55 DEG C, liquid to be tested is poured into the kettles, a sheet metal is pre-manufactured according to the technical requirement in the test and standard manual, the mass of the sheet metal is weighed, and the sheet metal is hung in the kettles in a suspended, semi-submerged and full-submerged mode and is kept standing for seven days. In order to prevent the liquid in the kettle from being evaporated, a set of condensation device is connected to the upper side of the kettles and is communicated with the kettle opening. After the test is finished, the sheet metal is taken out, washed and dried, the mass of the sheet metal is weighed and is compared with the mass before test, and the maximum corrosion rate is calculated.

Description

technical field [0001] The invention relates to a test device for liquid corrosion test of metal corrosion rate according to liquid or solid substance which may become liquid during transportation, and packing category classification according to the test result. Background technique [0002] The metal corrosion test device is a test device for testing the corrosion of liquids and solid substances that may become liquid during transportation. For chemical hazard testing and identification institutions, scientific research units that study chemical hazards, and production of corrosive liquids All products have application value. However, according to market research and literature retrieval, there is no relevant domestic institution to conduct metal corrosion tests in accordance with the requirements of the "Recommendation on the Transport of Dangerous Goods - Test and Standard Manual" (hereinafter referred to as the "Test and Standard Manual"). A similar test device has bee...
