Abstract

The invention provides a metallic slag oil-water base cleaning agent. The cleaning agent uses water as a solvent, and is characterized by comprising the following components by weight percent: 0.5-10% of a nonionic surfactant, 1.0-2.0% of an anionic surfactant, 1-5% of a dispersant, 0.4-10% of a compound corrosion inhibitor, 0.1-3% of a defoaming agent, and 52-97% of water. Under the normal temperature condition, the metallic slag oil-water base cleaning agent has high cleaning rate, and is capable of well replacing an organic solvent type cleaning agent, is free from corrosion to the metal, easy to prepare in use, simple in operation, free from combustion and explosion, safe and non-toxic.

Description

A kind of metal residual oil aqueous cleaning agent

Technical field

The present invention relates to a kind of clean-out system, be specifically related to a kind of metal residual oil aqueous cleaning agent.

Background technology

At present, in actual production, hardware and pipeline need regularly to remove greasy dirt.In oil refining apparatus, the materials such as a large amount of residual oil, slurry oil, greasy filth, dust are often accumulated especially in the surface of the part such as container, interchanger, pipeline, deposition tower.These dirts make the normal work of device influenced, and the danger of construction is increased, and them just can be kept to run well so regularly remove contamination to device and maintain.Fouling of heat exchangers is a ubiquitous problem in refinery's reliever at present, and fouling causes heat exchange final temperature to reduce, and waste fuel, increases operation difficulty.

Metal cleaner industry achieves and develops faster in recent years, of a great variety, but solid metal clean-out system solvability is poor, normal temperature cleaning performance is undesirable, need raised temperature to carry out clean-out operation, and this kind of metal cleaner often alkalescence is comparatively strong, easily damage is caused to metallic surface.There are many water base metal cleaning agents to come out at present, but in cleaning temperature, protection against corrosion, antirust, high-efficiency environment friendly etc., still have a lot of problem needing to improve, cannot replace solvents metalloid clean-out system completely, still have larger restriction in actual applications.

Summary of the invention

The present invention is intended to solve the deficiencies in the prior art, provides a kind of and can be applicable to normal temperature cleaning, efficient, low bubble, safety, environmental protection, water base metal cleaning agent with low cost.

The present invention for achieving the above object, provides a kind of metal residual oil aqueous cleaning agent, and this clean-out system is solvent with water, comprises following component by weight percentage:

Nonionic surface active agent 0.5 ~ 10%;

Aniorfic surfactant 1.0 ~ 20%;

Washing assistant 1 ~ 5%;

Composite corrosion inhibitor 0.4 ~ 10%;

Defoamer 0.1 ~ 3%;

Water 52 ~ 97%.

Described nonionic surface active agent is ethylene nonyl phenylate NP-10, alkylphenol polyoxyethylene OP-10, Oleum Cocois alkylolamide 6501, preferably 6501 (Oleum Cocois alkylolamides).

Described aniorfic surfactant is sulfonated α-olefin AOS, ethoxylated dodecyl alcohol sodium sulfate AES, preferred AOS (sulfonated α-olefin).

Described washing assistant is 4A type molecular sieve, sodium polyacrylate, propandiol butyl ether, Trisodium Citrate, the combination of preferred propandiol butyl ether and Trisodium Citrate.

Described composite corrosion inhibitor is chromic salt, molybdate, vanadate, nitrite, borate, preferred chromium hydrochlorate.

Described defoamer is dimethyl silicone oil.

Under room temperature, above-mentioned nonionic surface active agent, aniorfic surfactant are carried out pre-mixing, leave standstill after 10 minutes, then add washing assistant, composite corrosion inhibitor, defoamer, stir, obtain product.

The invention has the beneficial effects as follows:

Aq. type clean-out system all has very high cleaning rate under normal temperature condition, can well substitute organic solvent type clean-out system, corrosion-free to metal, and during use, preparation is easily, simple to operate, does not burn, does not explode, safety non-toxic.
