Abstract

The invention discloses a novel efficient and environment-friendly neutral deruster. The novel efficient and environment-friendly neutral deruster is characterized by comprising the following components in percentage by weight: 10-15% of organic phosphonate, 0.5-1.0% of OP-10, 0.3-0.5% of JFC, 0.2-0.3% of sodium gluconate, 0.1-0.2% of MS-575 and the balance of water. A preparation process of the novel efficient and environment-friendly neutral deruster comprises the following steps: weighing 10-15% of organic phosphonate and 0.2-0.3% of sodium gluconate respectively, and uniformly dissolving the organic phosphonate and the sodium gluconate with hot water at the temperature of 70-80 DEG C; adding running water in balance amount, and mixing uniformly; and adding 0.5-1.0% of OP-10, 0.3-0.5% of JFC and 0.1-0.2% of MS-575, stirring uniformly, and barreling. Compared with the prior art, the novel efficient and environment-friendly neutral deruster has the advantages as follows: the novel efficient and environment-friendly neutral deruster is convenient and safe to use, and very low in corrosion on a metal substrate self; in the derusting process, hydrogen gas is not produced, and the phenomenon of hydrogen embrittlement is not caused; the mechanized operation can be achieved; the preparation process is simple and easy to operate.

Description

A kind of neutral rust remover and manufacture craft thereof of novel high-efficiency environment friendly

Technical field

The neutral rust remover and the manufacture craft thereof that the present invention relates to a kind of novel high-efficiency environment friendly, belong to chemical technology field.

Background technology

At present, metallic element is in processing and storage and transport process, because metal working fluid rust-preventing characteristic used is poor or the factor such as weather, can produce corrosion in various degree, to next process operation or final sale of finished goods link, bring greatly and trouble, serious even directly cause product rejection and cause irremediable loss.Hand cleaning labour intensity is large, production efficiency is low, rust cleaning is not thorough; Shot peening efficiency ratio is higher, but part with threaded hole easily causes shot deposition in threaded hole; Inorganic acid acid pickling and rust removing in chemical rust removing, in treating processes, can produce a large amount of hydrogen makes steel produce " hydrogen embrittlement " phenomenon, intensity and the performance of iron and steel itself have been reduced, easily form acid mist simultaneously, affect operator's health and corrosion equipment and environment around, and easily cause excessive erosion, can not realize automatic batch production.Organic acid rust cleaning in chemical rust removing, it is than the inorganic acid energy safety of use in the past, effectively remove corrosion and the oxide compound thereof of metallic surface, keep the former glossy of metal simultaneously, but that part is processed the bad probability of returning rust is larger and metal itself is had to slight corrosion.

Summary of the invention

The present invention is in order to solve above-mentioned deficiency, and a kind of neutral rust remover and manufacture craft thereof of novel high-efficiency environment friendly is provided.

Above-mentioned purpose of the present invention realizes by following technical scheme: a kind of neutral rust remover of novel high-efficiency environment friendly, is characterized in that: the composition that comprises following weight percent:

Organic phosphonate: 10%～15%;

OP-10：0.5%～1.0%；

JFC：0.3%～0.5%；

Sunmorl N 60S: 0.2%～0.3%;

MS-575：0.1%～0.2%；

Water: surplus.

The manufacture craft of the neutral rust remover of novel high-efficiency environment friendly of the present invention is: take respectively 10%～15% organic phosphonate and 0.2%～0.3% Sunmorl N 60S, even with the hot water dissolving of 70-80 ℃, add the tap water of remaining ratio to mix, finally add 0.5%～1.0% OP-10,0.3%～0.5% JFC, 0.1%～0.2% MS-575, stir, filling barrelling.

The present invention's advantage is compared with prior art: the neutral rust remover of novel high-efficiency environment friendly of the present invention, easy to use and safety; Little to metallic matrix corrosion itself; In rust cleaning process, do not produce hydrogen, can not cause " hydrogen embrittlement " phenomenon; Can mechanized operation.Manufacture craft is simple, easy handling, and rust cleaning efficiency is high, and it is little that part returns rust probability; For corrosion part rust cleaning renovation, there are great economic benefit and social benefit.Meanwhile, because product pH value is neutral, use safety, corrosion-free to human body and metal material.

Embodiment

Below in conjunction with embodiment, the invention will be further described.

A neutral rust remover, comprise the composition of following weight percent: organic phosphonate: 12%; OP-10:1%; JFC:0.3%; Sunmorl N 60S: 0.3%; MS-575:0.1%; Water: surplus.

The manufacture craft of the neutral rust remover of novel high-efficiency environment friendly of the present invention is: take respectively 12% organic phosphonate and 0.3% Sunmorl N 60S, even with the hot water dissolving of 70-80 ℃, add the tap water of remaining ratio to mix, finally add 1% OP-10,0.5% JFC, 0.1% MS-575, stir, filling barrelling.

Rust remover of the present invention is easy to use, safe, and for the metallic element of general corrosion, the stoste of preparation is directly used, and temperature is controlled at 50-60 ℃, and ultrasonic cleaning can be removed general corrosion clean in 1 minute.Rust cleaning thoroughly and to change the liquid cycle long, can realize mass, automated operation, only need be according to the regular new liquid of interpolation of product Expenditure Levels in operation use procedure.Greatly improved production efficiency, the residual greasy dirt impurity in metallic surface etc. can be removed simultaneously clean, for next step cleaning rust-proof work brings great convenience.

Finally it should be noted that: above-described embodiment is only for example of the present invention is clearly described; and the not restriction to embodiment; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here exhaustive without also giving all embodiments; and apparent variation or the change of being amplified out thus, still among protection scope of the present invention.
