When the bearing cleaning agent is used, the bearing is soaked in the cleaning solution for 1-2 hours, and then the clean cleaning solution is taken for washing, so that the bearing cleaning agent is simple and convenient to use, non-toxic, pollution-free, non-flammable and non-explosive.
After the cleaning agent is cleaned by the cleaning agent,
in the invention, the etidronate tetrasodium, HEDP Na4, which is a sodium salt of HEDP, is an excellent calcium carbonate scale inhibitor, and HEDP Na4 is mainly used for metal corrosion inhibition of low-pressure boiler water treatment, circulating water treatment, industrial and municipal water for cleaning and swimming pool sterilization. HEDP Na4 is white powder solid, easily soluble in water, not hygroscopic, convenient for transportation, and suitable for use under severe cold conditions. HEDP Na4 belongs to organic phosphonate scale and corrosion inhibitor, can form stable complex with iron, copper, zinc and other metal ions, and can dissolve oxide on metal surface. It still has good corrosion and scale inhibition effects at 250 ℃.
