Phosphorus-free environment-friendly metal degreasing agent, production method and application method

Abstract

The invention discloses a non-phosphorus environment-friendly metal degreasing agent, comprising 30%-50% of a degreasing agent, 0.5%-1.5% of a defoaming agent, 1%-10% of a foaming agent, 1%-5% of a surface active agent and the balance of a complexing agent. The invention also discloses a production method of the non-phosphorus environment-friendly metal degreasing agent; and the method comprises steps of: evenly mixing the degreasing agent, the defoaming agent and the complexing agent, then adding the foaming agent and the surface active agent, and stirring until a completely uniform state to obtain the powdery non-phosphate environment-friendly metal degreasing agent. The invention also discloses a usage method of the non-phosphorus environment-friendly metal degreasing agent; and the usage method comprises the following steps: preparing a lotion; adding the metal to be washed into a washing trough, and washing the metal; and washing the metal with clear water. The metal degreasing agent provided by the invention has good cleaning effect on oil on surface of black metal, little corrosiveness, and insusceptibility to corrosion; the waste cleaning agent is convenient for treatment and beneficial to environmental protection; and the preparation process is simple and at low cost.

Description

technical field [0001] The invention relates to a metal degreasing agent, in particular to a non-phosphorous and environment-friendly metal degreasing agent having a good cleaning effect on oil stains on ferrous metal surfaces, a production method and a use method. Background technique [0002] Ferrous metals refer to iron, manganese, chromium and other alloys, such as steel, pig iron, ferroalloy, cast iron, etc. Both steel and pig iron are alloys based on iron with carbon as the main additive element, collectively referred to as iron-carbon alloys. Ferrous metals are widely used in metallurgical iron and steel industry, machinery manufacturing, shipbuilding, national defense industry, petroleum machinery industry, aircraft, automobile, motorcycle manufacturing, textile, hardware, mold, instrument, medical equipment industry, various steel industry chrome plating , galvanized deep processing and many other industries can be applied. In order to further improve the quality ...

Problems solved by technology

However, after the traditional degreasing and stain removal treatment, the outer surface of the ferrous metal often has pockmarks, that is, there are irregular surface defects; and the surface is prone to scarring, because the steel material is uneven and there are many impurities. Impurities are exposed after degreasing and stain removal, resulting in scarring

Therefore, burrs will appear on the surface of the metal workpiece after the traditional degreasing and stain removal treatment, and the contact between the workpiece and the workpiece will cut the surface. Deep cuts will reduce the strength of the workpiece and reduce the performance of the equipment, resulting in potential safety hazards for the equipment.

In addition, because the traditional degreasing agent contains phosphorus, it has a large environmental pollution and is not conducive to environmental protection.
