Abstract

The invention discloses an interprocess dehydrating agent which is prepared from an active component and solvent oil. The active component is at least one of alcohol and alcohol ether; the mass percentage of the active component is 0.1 to 15 percent, and the mass percentage of the solvent oil is 85 to 99.9 percent. The interprocess dehydrating agent provided by the invention is nonflammable, safe,reliable, simple in components, low in cost, fast to dehydrate, good in dehydrating effect, and particularly suitable for dehydrating and drying between metal processing procedures.

Description

technical field [0001] The invention relates to the technical field of chemical products, in particular to an inter-process dehydrating agent. Background technique [0002] Typically, metal processing includes processes such as forming, machining, cleaning, drying, and packaging. However, a small amount of moisture remaining on the surface of metal parts before packaging can easily cause corrosion of the workpiece during storage, transportation and use. On the one hand, a small amount of moisture will affect the anti-rust cycle of dry packaging such as anti-rust film or anti-rust bag; Anti-rust properties. Therefore, before sealing the packaging, it is necessary to treat the metal parts with a dehydrating agent to effectively remove water stains on the metal surface. [0003] In view of this, it is necessary to develop a dehydrating agent between processes to meet the requirements of rapid dehydration between metal processing processes and long-term storage and rust preve...
