Embodiment Construction
[0025] Such as figure 1 As shown, the detection device for liquid corrosion of the present invention includes a box-type microwave reactor 1, and the cavity size of the microwave reactor 1 is enough to put a volume into a cup-shaped reactor 6 with a four-mouth cover 7 of 3L. The interfaces are all frosted, and the caliber is 24mm, which can accommodate 50mm×20mm×2mm (length×width×thickness) steel or aluminum sheets. There is a small hole at the center of the top of the microwave reactor 1, through which the two-port connecting pipe 10 can be inserted to facilitate external connection of various auxiliary equipment. The small hole is provided with a microwave choke 4, which uses choke technology to suppress microwave leakage. One port of the two-port connecting pipe 10 is connected to the digital display agitator 8, and the stirring rate can be precisely adjusted through the digital display controller to meet different work requirements; the other port is connected to the cond...

The invention mainly relates to a device for detecting the corrosion of liquid through controlling reaction temperature by utilizing microwave radiation, which comprises a box-type microwave reactor. A cup-shaped reactor with a four-opening cover is arranged in the reactor; the central position of the top part of the reactor is provided with a small hole; the position of the small hole is provided with a microwave choke; a two-opening connecting pipe is inserted through the small hole; one opening of the two-opening connecting pipe is connected into a digital display stirrer; and the other opening of the two-opening connecting pipe is connected into a condenser. In the device for accelerating the detection on the corrosion of the liquid through controlling the reaction temperature by microwave radiation heating, the advantages of the specific body heating action, the high heating speed and the like of a microwave are fully utilized to replace a traditional water bath temperature control method, thereby, the testing time is effectively shortened.
Description
technical field [0001] The invention relates to the test of the corrosivity parameters of liquids to metals, in particular to a device for detecting the corrosivity of liquids by using microwave radiation to control the reaction temperature. Background technique [0002] Chemical hazard detection is a necessary means to assess the hazards of chemicals in production, storage, transportation and other links. The risk of metal corrosion is a necessary item in the risk assessment of chemicals, and its hazards are mainly reflected in the corrosion hazards caused to other goods or means of transportation. At present, according to literature retrieval and market research, there is no similar domestic institution that has designed a similar test device for metal corrosion testing (Tianjin Entry-Exit Inspection and Quarantine Bureau has applied for a utility model: Dangerous goods metal corrosion tester (application No.: 200920096847.9), the purpose of the invention of this utility ...
