Abstract
The present invention discloses a manufacture method for ferrous metal gas phase rust preventing agent. The ferrous metal gas phase rust preventing agent produced by the present invention can effectively combine the cost, the effect, and the gas phase together, thereby filling the market blank. The present invention is realized through the following technical proposal: ammonium monohydric phosphate is 17 percent, ammonium bicarbonate is 6 percent, sodium nitrite is 27 percent, and water is 50 percent; wherein, the water is heated by 30-40 DEG C according to amounts by weight, sodium bicarbonate is added, after the mixing for dissolution, the ammonium monohydric phosphate is added gradually, then the sodium nitrite is added, and the materials are mixed until being completely dissolved. The method that packaging and sealing are performed after the agent is soaked or coated in a brushing way on an antirust substance can be adopted.
Description
Technical field
The invention relates to the manufacture method of rust-preventive agent, more particularly, the invention relates to the manufacture method of ferrous metal gas phase antirust agent.
Background technology
Rust-preventive agent is varied, and rust-proof effect has nothing in common with each other, and has many rust-preventive agent effects rather good, right function singleness, this agent can be effectively with cost, effect, and gas phase combine, filled up the blank in market.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, can be effectively with cost, effect, and gas phase combine, the gas that product itself volatilizes can play a protective role to ferrous metal under airtight condition, has filled up the blank in market.
The present invention is achieved by following technical proposals.
The manufacture method of ferrous metal gas phase antirust agent of the present invention comprises following composition (by weight percentage): DAP 17%～19%, ammonium hydrogencarbonate 5%～6%, Sodium Nitrite 27%, water 50%.
Heat water to 30～40 ℃ by formula ratio, add sodium bicarbonate, after the stirring and dissolving, add DAP gradually, add Sodium Nitrite again, can use after being stirred to whole dissolvings.
Before the use, should be antirust with carrying out after metallic surface decontamination, oil removing and the drying.Because this agent is the vapor phase inhibitor of mixed type, adopts with solution mostly or be coated with form such as paper, and use behind the package encapsulation in addition.If use with solution, can adopt dipping or brush after package encapsulation again.If use to be coated with the paper mode, content is at 20～30 gram/rice on the general paper
2About.
Note during use:,, just can play the volatile rust prevention effect so must note package encapsulation during this agent of use because this agent is volatile in air.
Embodiment
The invention will be further described below in conjunction with embodiment.
Formation of the present invention is; (by weight percentage) DAP 17%～19%, ammonium hydrogencarbonate 5%～6%, Sodium Nitrite 27%, water 50%.
Heat water to 30～40 ℃ by formula ratio, add sodium bicarbonate, after the stirring and dissolving, add DAP gradually, add Sodium Nitrite again, can use after being stirred to whole dissolvings.
