The invention relates to a novel stock fluid deironing method and a device, which is characterized by comprising a stock fluid deironing process and a magnetic rod washing process, wherein the tock fluid deironing process is that: the stock fluid flows upwards from the bottom part of a vertical cavity, and the stock fluid flows out to a stock groove from an outlet on the side surface of the upperpart of the cavity after being deironized by a permanent-magnetic body rod which is vertically arranged inside the cavity; and the magnetic rod washing process is that: the stock fluid deironing process is firstly stopped, then a scraping sleeve which is previously arranged on the top part of the permanent-magnetic rod is moved downwards along the permanent-magnetic body rod through a power mechanism, so the ferromagnetic substance which is attached onto the permanent-magnetic body rod is scraped onto a non-magnetic conductive material rod on the lower end of the permanent-magnetic body rod, the ferromagnetic substance is washed away from the non-magnetic conductive material rod on the lower end of the permanent-magnetic body rod through a washing device, the washed-away ferromagnetic substance is discharged through a drain valve which is arranged below the cavity, and the scraping sleeve is pulled back to the top part of the permanent-magnetic rod through the power mechanism so as toreprocess the stock fluid deironing process. Compared with the prior art, the novel stock fluid deironing method has the advantages that the cleaning steps are fewer, the actuating mechanisms are fewer and the actuating mechanism is free from being influenced by the penetration of the stock.

The present invention relates to the field of medical conductive liquid, in particular to a conductive liquid for electroencephalogram sensors, comprising the following components in mass percentage: 2%-10% of salt electrolyte, 0.1%-1% of lipase, and 2%-20% of moisturizing agent , gel forming agent 10%-20%, preservative 0.1%-1%, the rest is deionized water, and the pH value of the electroencephalogram sensor conductive liquid is 8-9. Lipase is added to the conductive liquid of the EEG sensor of the present invention, and the conductive liquid is adjusted in the optimum pH value range, so that the conductive liquid is enzymatically decomposed into fatty acid sodium when it contacts grease, reducing the interference of grease to the electrodes for collecting human body electrical signals, Increase the sensitivity of the electrodes for signal collection and the test accuracy of the EEG sensor.

The invention relates to an L ED module three-proofing paint spraying clamp and an application method thereof; the clamp comprises four crossbeams connected in sequence to form a sealed rectangle; four sides of the crossbeams are respectively provided with a groove and a channel outside the groove; the clamp also comprises four corner connectors, and two adjacent edges of the corner connector are provided with holes; a plurality of support racks are relatively arranged on two opposite crossbeams, and the support rack comprises a rack body, and a handle and a boss arranged on the rack body; the center of the handle is provided with a hole; the boss is provided with a positioning rod; bolts movably connect the four crossbeams in a whole body through the four corner connectors, and movably connect the support racks on the crossbeams; the method can adjust positions of the crossbeams and support racks, so the positioning rods on the support racks can fix positioning holes on the module; when four positioning holes of the module are fixed by the positioning rods, spray paint work can be carried out on the module. An existing clamp is long in adjusting time, easy to loosen, single in usage product, and can pollute the module; the L ED module three-proofing paint spraying clamp can solve the said problems, and simple and easy in operation method.
