Abstract
The invention provides a metal rust remover and a preparing method thereof. The metal rust remover is composed of sodium silicate, phosphoric acid, a surface active agent, a reducing agent, magnesium stearate, an adhesion promoter and deionized water. The invention also provides a preparing method of the metal rust remover. The raw materials are sequentially added into a reactor with a stirring device to be stirred and dissolved to obtain the product; and the metal rust remover can be diluted to be used, has the excellent effect for removing ferric oxide, hematite oxide and the like and can be widely applied to the field of cooling water treatment, low-pressure boiler water treatment, reverse osmosis water treatment and the like.
Description
Technical field
The present invention relates to water treatment field, relates in particular to water treatment agent, particularly relate to a kind of Deruster for metal and
Its preparation method.
Background technology
China's most area is particularly northern area water resource relative scarcity, with expanding economy and people's lives water
The demand of flat raising, industrial or agricultural and domestic water increases year by year, and the exploitation of water resource become more and more important.At me
In the water resource of state, subsoil water is a kind of most valuable resource, because with being distributed, wide, water quality is good, be difficult the features such as polluting, just
By development and application more and more widely.But because iron-holder is very high in nature rock matter situation subsoil water itself, using
Metal surface can often be corroded in journey, the development and more and more extensive, the metallic steel of reverse osmosis applications with recirculated cooling water technology
The corrosion problem of material etc. becomes increasingly conspicuous, and the metal material and the weight of equipment that the whole world is scrapped every year due to corrosion is about metal
More than 20 parts of annual production, take metallic article rust cleaning before various anti-corrosion measures to be primary processing step.At present, rust cleaning side
The predominantly organic tool method of method, the big class of chemical method two, Mechanical Method be by manually strike shovel, polishing, have the disadvantage high labor intensive, efficiency it is low,
Dust pollution is serious, and rust deposite is difficult to clean off totally, and chemical method has good effect, efficiency high, the simple cost of technological operation low excellent
Point；But the chemical treatment rust remover of routine is all acid, while removing rust is removed in cleaning, can also cause molten to metal surface
Erosion, causes new corrosion, therefore, when using conventional acid rust remover, typically also need to coordinate corrosion inhibiter to use simultaneously, not only
Using troublesome poeration, and increase cost, and the discharge of cleanout fluid will also result in environmental pollution after eliminating rust.
The content of the invention
The present invention is directed to above-mentioned problem and shortage, there is provided a kind of Deruster for metal and preparation method thereof, in this
Property rust remover without acidity, do not result in the metal erosion problem in rust cleaning cleaning process, without adding special corrosion agent, profit
In operation, relief liquor is to environment non-hazardous.The weight portion of each component of the present invention is：Sodium silicate 5-20 parts, phosphoric acid 2-15 parts, surface
Activating agent 5-10 parts, reducing agent 15-30 parts, magnesium stearate 1-3 parts, accelerator 5-10 parts, remaining is deionized water.
Invention also provides a kind of preparation method of Deruster for metal, in the reactor with agitating device successively
The surfactant of above-mentioned mass parts, reducing agent, magnesium stearate, accelerator, water stirring and dissolving is added to obtain product of the present invention, this
Bright Deruster for metal can dilute and use, and with the excellent effect for removing ferrum oxide, red iron oxides etc., can be widely used for cold
But the field such as water process, low-pressure boiler water process and anti-penetration wastewater disposal.
Described surfactant is dodecylbenzene sodium sulfonate, alkanolamide, fatty alcohol-polyoxyethylene ether, triethanolamine
In one or two.
Described reducing agent is one or more in sodium sulfite, carbohydrazide, hydroquinone, Methylethyl oxime.
Described accelerator is any one in nickel sulfate, cobaltous sulfate.
The preparation method of Deruster for metal, it is characterised in that：To add in the reactor with agitating device first a certain amount of
Deionized water, start to warm up, when water temperature reaches 40 DEG C, open agitating device and start stirring, by mass of surface activating agent, also
Former agent is added thereto, and adds magnesium stearate, accelerator to continue to stir 10-15 minutes, static placement 2 hours after 10 minutes.
The beneficial effect of the Deruster for metal in the present invention be can remove the rust of metal surface, oily coating and
Organic impuritiess, and corrosion of metal will not be caused in descaling process, it is convenient to operate, save without the need for the use of corrosion inhibiter
Cost, will not be to environment and harm.The product of the present invention used in new system, can set up cleaning and protect system
System, as the beginning for ensureing process efficiency and maintained equipment.This product is specifically designed for effectively dissolving rust deposit, while
Passivation parent metal.
