Problems solved by technology

At present, the cleaning agents in the market have different defects. The extensive use of phosphorus-containing chemical substances and nitrogen-containing corrosion inhibitors has caused great pollution to the environment. With the continuous improvement of domestic and foreign requirements for energy saving, environmental protection and sewage discharge , Traditional industrial cleaning agents are gradually banned by local regulations due to the presence of pollutants such as P and N. The new green phosphorus-free and nitrogen-free cleaning agent technology has gradually matured and developed rapidly

Abstract

The invention discloses an environment-friendly and energy-saving phosphor-free and nitrogen-free industrial cleaning agent. The environment-friendly and energy-saving type phosphor-free and nitrogen-free industrial cleaning agent is prepared from the following components: an alkali metal compound, a micromolecular polyhydric alcohol, a surfactant and the like, wherein the alkali metal compound isan organic or inorganic compound and a derived structural compound of one or a mixture of more compounds containing sodium and potassium, including sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium silicate, potassium silicate and the like without nitrogen and phosphorous structures; the micromolecular polyhydric alcohol is an alcohol, carbohydrate, aldehyde andacid compound containing two or more than two hydroxyls in a molecule and including glycerol, gluconic acid, maleic acid and the like without nitrogen and phosphorous structures, a general formula isCnHn-xOHx (x is greater than or equal to 2). The environment-friendly and energy-saving phosphor-free and nitrogen-free industrial cleaning agent has the advantages that the environment-friendly effect is realized, phosphorous and nitrogen are not contained, the cleaning ability is good, the dirt removal ability is strong, combustion and explosion are avoided, the safety in use is realized, the pollution to environment is avoided, energy sources are saved, the cleaning cost is low, and the good corrosion inhibiting protection function is realized on the cleaning substrate.

Description

technical field [0001] The invention relates to an environment-friendly industrial cleaning agent, in particular to an environment-friendly, energy-saving, phosphorus- and nitrogen-free industrial cleaning agent. Background technique [0002] Metal cleaning is one of the indispensable processes in mechanical processing, because in different metal processing processes, various types of dirt may adhere to the surface of metal parts and equipment. Only by fully cleaning these dirt can the next process be guaranteed. The smooth progress and the processing quality of the product. For different types of dirt, chemical pickling (mainly removes metal oxides), chemical alkali cleaning (removing animal and vegetable oils), organic solvent cleaning (dissolving dirt by solvents) and water-based cleaning (surfactant as the main active group) are often used. Minute). At present, the cleaning agents in the market have different defects. The extensive use of phosphorus-containing chemical...
