Device for automatically testing corrosion resistance of stainless steel tableware

Abstract

The invention discloses a device for automatically testing corrosion resistance of stainless steel tableware. The device comprises a support, an actuating mechanism, an anti-evaporation barrel and a liquid container. The actuating mechanism is installed on the support. The actuating mechanism is provided with a sample connecting piece for connection with a stainless steel tableware sample. Specified corrosive liquid is put into the liquid container. A heating mechanism is arranged in the liquid container. The anti-evaporation barrel is arranged at an upper part of the liquid container. The anti-evaporation barrel is provided with a barrel cover. The barrel cover is provided with a hole allowing expansion of the actuating mechanism. Compared with the prior art, the device for automatically testing corrosion resistance of stainless steel tableware can realize a corrosion resistance test on stainless steel tableware under technical conditions specified in the national standard, realize automatic operation, reduce labor intensity and save labor power.

Description

technical field [0001] The invention relates to the field of stainless steel tableware testing, in particular to an automatic testing device for the corrosion resistance of stainless steel tableware. Background technique [0002] At present, the relevant national standards on stainless steel tableware (GB / T15067.2-94) stipulate that stainless steel tableware must be tested for corrosion resistance, and the test requires that the sample be periodically soaked in a 1% sodium chloride solution at a temperature of 60 °C , After the specified time, use a microscope or magnifying glass to observe the size and quantity of the corroded pits. The continuous test for ordinary stainless steel is 3 hours, and the continuous test for high-grade stainless steel is 6 hours. ~3 times / min. The standard stipulates the basic requirements of the test method and test device, but in actual work, we find that there is still a lack of test devices that meet this requirement, especially the specifi...
