Abstract
The invention discloses an inorganic acid washing agent. The inorganic acid washing agent comprises the following components in parts by weight: 6 to 12 parts of hydrochloric acid, 0.2 to 0.5 part of corrosion inhibitor, 0.01 to 0.03 part of nonionic surface active agent, 1 to 3 parts of nitric acid, 2 to 4 parts of methenamine, 0.2 to 0.4 part of rodine, 0.1 to 0.3 part of acetic acid, 0.2 to 0.5 part of EDTA and the balance of water. The inorganic acid washing agent has characteristics that the price is cheap, the production cost is low, the corrosion on a stainless steel device and an aluminum alloy device can be avoided, and the inorganic acid washing agent is suitable for washing the special metal devices; and moreover, the washing speed can be increased by virtue of appropriate heating, the rust on the surface of the metal can be effectively eliminated, and various dirt such as tar, seaweeds organisms and the like can be eliminated.
Description
Technical field
The invention belongs to chemical field, specifically relate to a kind of inorganic acid scavenger.
Background technology
Acid-alkali clean-out system by means of with dirt generation acid-base reaction, sometimes also with reactions such as oxidation-reductions, make dirt change solubilized into or be scattered in the clean-out system of scavenging solution, being acid or alkaline salt after being mostly mineral acid, alkali and hydrolysis, sometimes also using organic acid.
The auxiliary agent that most of acid-alkali clean-out system all adds necessity by the aqueous solution that is sour, alkali forms.Another kind of under the high temperature conditions with the acid of molten state and dirt digestion or alkali, make originally not dissolve or difficulty is dissolved in dirt in cleaning restraining, be converted into diffluent compound, this kind of acid or alkali are commonly referred to melting agent.When this clean-out system is difficult to for solvent or solution the dirt removed, there is good effect.
The advantage making scavenging solution with sulfuric acid is its low price, does not have corrodibility to stainless steel and aluminium alloy equipment, is applicable to these Special Metal equipment of cleaning.Sulfuric acid is again the not volatile strong acid of one, so can accelerate cleaning speed by suitably heating.Usually nonionogenic tenside is added to improve its rust cleaning ability when general industry utilizing sulfuric acid clean.Adding appropriate nitric acid in sulfuric acid and can remove the multiple dirts such as tar, Jiao Yan, seaweeds biology, a certain amount of inhibition dosage will be added to reduce sulfuric acid to the corrodibility of metal object in clean-out system.
Summary of the invention
The present invention relates to a kind of inorganic acid scavenger, it has low price, the advantage that production cost is low, and corrodibility is not had to stainless steel and aluminium alloy equipment, be applicable to these Special Metal equipment of cleaning, and cleaning speed can be accelerated by suitably heating, effectively can remove the corrosion of metallic surface, moreover, the multiple dirt such as tar, seaweeds biology can also be removed.
Inorganic acid scavenger of the present invention is made up of following formula and the cooperation of quality component forms: hydrochloric acid 6 ~ 12 parts, inhibiter 0.2 ~ 0.5 part, nonionogenic tenside 0.01 ~ 0.03 part, 1 ~ 3 part, nitric acid, urotropine 2 ~ 4 parts, if fourth 0.2 ~ 0.4 part, acetic acid 0.1 ~ 0.3 part, EDTA0.2 ~ 0.5 part, surplus is water.
A kind of manner of formulation of inorganic acid scavenger is: if the sulfuric acid of aforementioned proportion, inhibiter, nonionogenic tenside, nitric acid, urotropine fourth, acetic acid, EDTA are joined in a certain amount of water, stir and can obtain this inorganic acid scavenger.
