Common cleaning agent for flange bolts to remove oil
Flange bolts are the more common bolts in fasteners and can play a large role in many places. Flange bolts often have oil stains during use. How do you clean the oil on the flange bolts? Today, Xiaobian talks about the commonly used cleaning agents for flange bolts to oil. I hope I can use it to help everyone.
1, synthetic cleaning agent
Synthetic cleaners differ from standard alkaline cleaners in that they differ in chemical composition and are also an alkaline cleaner. Standard alkaline cleaners are essentially inorganic, while synthetic agents are organic agents containing amine-based materials. These products are designed to clean up alkaline residues in a single stage of cleaning and are also good rust inhibitors. Synthetic cleaners are used for moderately difficult cleaning, such as quenching oil or quenching polymer solutions on the surface of flange bolts.
2, soluble emulsion cleaning agent
Soluble emulsifiers usually contain soil, solvents, emulsifiers, builders, corrosion inhibitors and small amounts of water. The role of water is to dissolve the emulsifier, which dissolves the dirt on the surface of the flange bolts and also leaves a rust-proof film on the surface. The emulsifier and detergent can hold the grease particles and dissolve them into a cleaning agent containing a solvent and an oil. The emulsified cleaning agent is a concentrated pure oil product which, after being diluted in water, becomes a white emulsion liquid.
3, acid cleaning agent
It is not an effective method to clean the general dirt on the flange bolts with an acidic cleaner, and an alkaline cleaner is usually used. It is very effective to clean the special deposits such as scales with acid. The famous process is acid leaching. In addition to rolling, welding and heat-treating the oxide layer, surface oxides, rust and corrosion products that affect the quality of the plating or oil seal, as well as water-stained deposits, can be removed with acid. Commonly used are organic acids such as sulfuric acid, hydrochloric acid, nitric acid, and citric acid and acetic acid. For the dephosphorization of high-strength flange bolts before heat treatment, the first three cleaning processes are mainly used, but hydrogen corrosion should be prevented. The acid agent should contain a base acid and a corrosion inhibitor to prevent erosion of the flange bolt surface, as well as a surfactant that improves cleaning ability.
4, alkaline cleaner
The alkaline cleaner is prepared by mixing a detergent and an alkaline earth metal salt of a surfactant, and is a widely used cleaning agent. The starting point for adding each salt and surfactant is to ensure the cleaning effect, followed by the economy. The pH of the cleaning agent is required to be around 7. The cleaning ingredients of such cleaning agents are hydroxides, silicates, carbonates, phosphates, borates, and organic compounds.
The above is about the common cleaning agent for flange bolts to remove oil. I hope that everyone can understand the cleaning of flange bolts after cleaning the oil. It is helpful for everyone to clean the flange bolts.
