Abstract
The present invention relates to chemical industrial technology, and is especially one kind of cleaner specially for cold rolled steel plate before annealing. Technologically, the present invention features that the cleaner contains special non-ionic surfactant less than 10 wt%, alkali compound 5-40 wt%, chelating agent 0.5-10 wt%, co-solvent 2-10 wt% and solvent 5-10 wt%. The cleaner is used in cleaning cold rolled steel plate before annealing, and has the features of less foam, high detergency, capacity of being used in different washing modes, including showering, brushing and electrolytic cleaning, etc.
Description
Technical field
The present invention relates to the chemical industry field, relate in particular to a kind of clean-out system that is used to clean the preceding cold-rolled steel sheet of continuous annealing.
Invention
Iron And Steel Industry develop rapidly at present, according to parties concerned's introduction, after the reform and opening-up, China has kept average annual growth more than 5% to the consumption of iron and steel, and this demand will increase fast in national economy, particularly under the drive of automobile, the manufacturing fast development of Architectural Equipment, to continue to keep rate of growth faster, especially after China joined WTO, the Chinese utmost point may become first in the world production country, and that will can't be estimated especially to the potential of demand of iron and steel.High-grade steel products field with high content of technology in part, that added value is bigger, domestic needs has bigger growth space.At present, China's Cold Rolled Sheet Steel breach is about 38%, the steel plate galvanized breach is about 40%, the tin plate breach is about 33%, no matter the cold rolled sheet steel plate still is steel plate galvanized and tin plate, it is exactly cleaning after cold rolling that an indispensable process is all arranged in its production process, thereby also very high to the requirement of clean-out system.
The purpose of this invention is to provide a kind of be used to the clean low bubble of the preceding cold-rolled steel sheet of continuous annealing, the clean-out system of strong detergency.
Technical scheme of the present invention
Usually the dirt on the cold rolling strap steel plate mainly is cold rolling liquid, slushing oil and carbon granules and iron powder.And the cold rolling liquid that is used for cold-rolled steel sheet is normally natural or the animal and plant grease of synthetic.At present, the travelling speed when domestic cold rolling strap steel plate cleans is 150 meters-700 meters/minute, that is to say that the time that stop in rinse bath on the steel plate only has an appointment 1-6 second at every.And also to carry out surface coating after the steel plate cleaning and handle.If the residual low amount of dirt of surface of steel plate after cleaning will cause that plated film is inhomogeneous, the plated film steel plate that breaks cancels.According to the character and the wash conditions of dirt on the cold-rolled steel sheet, the material that clean-out system of the present invention adopts should be: the first, have high specific conductivity; The second, clean effect is thorough rapidly; The 3rd, foam is extremely low.Because often comprise high-pressure spraying in the typical cleaning, scrub and electrolytic cleaning, how steep evil spirit and easily overflowed rinse bath, influence ordinary production.Therefore, the present invention mainly is made up of extraordinary nonionogenic tenside, ultralow bubble amphoterics and sequestrant.This product can be used for spray, scrub and electrolytic cleaning.
Its concrete weight percent prescription is:
(a) basic cpd: 5-40%, this alkalify thing is an alkali metal compound, as: sodium hydroxide, potassium hydroxide, lithium hydroxide, thanomin, diethanolamine, trolamine etc.
(b) nonionogenic tenside: be 0-10%, they are: alkylphenol polyoxyethylene, alkyl alcohol Soxylat A 25-7, alkyl polyoxyethylene polyethenoxy ether, wetting ability is that HLB is 2-14, preferably 4-7 with the hydrophobicity ratio.
(c) sequestrant: 0.5-10%, they be following one or more: organic multicomponent phosphonic acids type has amino alkylidenyl polyphosphonic acid or its salt, basic metal ethane 1-hydroxyl di 2 ethylhexyl phosphonic acid or its salt, WSI 3310 or its esters.In this compounds, have diethylene triamine pentamethylene phosphonic, ethylene diamine tetra methylene phosphonic acid sodium, hexanediamine tetramethyl commonly used are pitched Alendronate, Amino Trimethylene Phosphonic Acid salt and 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid salt etc.
(d) special efficacy solubilizing agent: 2～10%, they be following one or more: the alkylsulphonic acid class alkylbenzene sulfonate, sulfonated alkyl naphathalene arranged; The ethanol of short carbon chain alcohol, Virahol; Also have amphoterics tetrahydroglyoxaline, trimethyl-glycine etc.
(e) solvent: 5～10%, solvent is used for further increasing the soil release characteristics of product.Primary solvent has glycol ether, diethylene glycol ether, card butanols ether.
(f) water: surplus.
Advantage of the present invention
The present invention is owing to selected extraordinary nonionogenic tenside to make its cold-rolled lubricating oil to surface of cold-rolled steel plate, slushing oil and carbon granules and iron powder have extremely effectively removal and dissemination, additional benefit of the present invention be selected can the good foam of clean effect is extremely low the solubilizing agent of surface active agent solubilization in the polyelectrolyte solution, at the bottom of the present invention the 3rd advantage is foam, strong detergency
