Description
Technical field
The present invention relates to clean-out system technical field, particularly relate to a kind of can the clean-out system of in line environment protection water-based ultrasonic cleaning steel plate.
Background technology
In SMT manufacturing processed, brush the operation of DIP welding from red offset printing, many steel plates need cleaning, and the carrier such as remaining the pcb board of rosin, wave-soldering furnace and pcb board after remaining the pcb board of rosin, the condenser of backflow, DIP wave soldering after the tin cream steel plate after fixing red offset printing brush copper mesh, print solder paste, backflow all needs cleaning.
For the cleaning of the tin cream steel plate after print solder paste, mostly traditional cleaning steel plate agent is inflammable and explosive volatile-type organic solvent or alkaline water-based cleaning agent.
The cleaning steel plate agent of traditional inflammable and explosive class is generally mixed alkanes or alcohols, easily employment injuries occurs and high to fire-fighting requirements management degree.In addition, the cleaning efficiency of traditional inflammable and explosive volatile organic solvent is lower, often can only clean for single steel plate, if and when will clean multi-disc steel plate simultaneously, then need to spray phosphorus in this clean-out system, ultrasonic wave just can not be coordinated to clean once spray phosphorus clean-out system, cleaning performance is undesirable, therefore, traditional inflammable and explosive volatile organic solvent can only clean steel plate one by one.
Traditional alkaline water-based cleaning steel plate agent adopts the compositions such as butyl, monoethanolamine, potassium hydroxide and deionized water usually, though such clean-out system can adopt ultrasonic cleaning, but can not directly discharge after cleaning, work the new environmental law preparing to perform on January 1st, 2015, to be more and more higher to the requirement of clean-out system, existing clean-out system cannot reach the requirement of environmental law.
Summary of the invention
In order to adapt to new environmental law, the object of the invention is to for the deficiencies in the prior art, there is provided a kind of can the clean-out system of in line environment protection water-based ultrasonic cleaning steel plate, it can realize large quantities of steel plate and clean simultaneously, and cleaning efficiency is high, and cleaning performance is good, waste water after cleaning can directly discharge, reduce the pollution of discharge water, reduce employment injuries, improve security against fire.
The present invention is achieved through the following technical solutions.
Can the clean-out system of in line environment protection water-based ultrasonic cleaning steel plate, comprise the raw material of following mass percent:
Dissolve wetting agent 2-10%
Wetting auxiliary 1-5%
Defoamer 0.01-0.05%
Deionized water surplus
Wherein, the mass percent sum of above raw material is 100%;
Wherein, described dissolving wetting agent is one or more the mixture in diethylene glycol monobutyl ether, 1-Methoxy-2-propyl acetate, propylene carbonate, and described wetting auxiliary is isomeric alcohol polyethenoxy ether or fatty alcohol-polyoxyethylene ether.
Tin cream residual on steel plate is mainly dissolved in the effect of dissolving wetting agent, and soaks steel plate, convenient cleaning.Diethylene glycol monobutyl ether, molecular formula is C

3, be that one has multi-functional non-public hazards solvent.Be mainly used in the solvent of ink, paint, ink, textile dyestuff, textile finish oil, also can be used for the clean-out system in production of liquid crystal displays.In the molecule of 1-Methoxy-2-propyl acetate, existing ehter bond, has carbonyl again, and carbonyl defines again the structure of ester, simultaneously again containing alkyl.In same a part, existing nonpolar moiety, has polar portion again, and this two-part functional group both restricted repulsion mutually, plays again its intrinsic effect separately.Therefore, certain dissolving power is had to apolar substance and polar material.
Propylene carbonate, is also called propylene carbonate, molecular formula: C
4h
6o
3, colourless odorlessness, or light yellow transparent liquid, water-soluble and tetracol phenixin, with ether, acetone, benzene etc. are miscible.It is a kind of excellent polar solvent.This product is mainly used in polymer operation, gas separating technology and electrochemistry.Particularly be used for absorbing Sweet natural gas, petrochemical plant synthetic ammonia feedstock carbonic acid gas wherein, also can be used as softening agent, spin solvent, alkene and aromatic hydrocarbons extraction agent etc.As the softening agent of sizing agent and sealing agent.Also can be used as the dispersion agent of phenolic resin curing promotor and Water-soluble adhesive color stuffing.
1-Methoxy-2-propyl acetate and propylene carbonate coordinated, be conducive on the one hand infiltrating in tin cream, play a part to dissolve tin cream, also play the effect of wetting steel plate, be conducive to cleaning steel plate, cleaning performance is good.
Wetting auxiliary is conducive to soaking steel plate further, convenient cleaning.Isomeric alcohol polyethenoxy ether, as the chemical product that tensio-active agent is a kind of, is mainly divided into isomery ten polyoxyethylenated alcohol, isomery undecyl alcohol Soxylat A 25-7, isomerous tridecanol polyoxyethylene ether etc. several.Composition: the polymkeric substance of isomery alcohol and oxyethane, belongs to nonionic surface active agent.Isomeric alcohol polyethenoxy ether is conducive to reducing surface tension, and soaks steel plate, and cleaning performance is good.
Fatty alcohol-polyoxyethylene ether (AE), is also called polyoxyethylene aliphatic alcohol ether.It is with fastest developing speed in nonionogenic tenside, that consumption is maximum kind.Such tensio-active agent is that the ehter bond in its molecule is not easily destroyed by acid, alkali, so stability is higher, better water-soluble, electrolyte-resistant, is easy to biological degradation, and foam is little by the ether of polyoxyethylene glycol (PEG) with fatty alcohol condensation.Fatty alcohol-polyoxyethylene ether is conducive to reducing surface tension, and soaks steel plate, and cleaning performance is good.
