Description
Technical field
The present invention relates to metal conditioner technical field, more particularly to a kind of magnetic polyethylene glycol to fix degradation bacteria and answer
The agent of mould assembly powder cleaning and cleaning.
Background technology
Metal is carrying out before processing, it is necessary to washes the dirts such as antirust oil, the cutting fluid on surface, traditional metal surface is clear
Washing lotion is formulated based on alkali, phosphate builder, nonyl phenol or octyl group phenols surfactant, operating temperature during cleaning
Generally higher than 80 DEG C, the process energy consumption is big, and the surfactant containing phenols used has a bio-toxicity, and difficult degradation is residual in water body
The time is stayed to grow, if phosphate therein is not handled thoroughly during liquid waste processing, P elements therein can largely carry out natural water,
So as to cause the eutrophication problem of water body.
Zhang Xiaoming exists《The research of the without phosphorus degreasing powder of steel and iron parts》In one text by contrast test test it is different without phosphorus and
The performance of sodium triphosphate, consider the performance such as wash-aid effect and the binding force to calcium ions and magnesium ions, it is organic to have selected silicon silicic acid
Carboxylic acid polymeric modification thing is as builder, and to substitute phosphate builder, this builder is not phosphorous, fundamentally solves
The processing of phosphorus and emission problem in waste liquid, while employ a kind of table outstanding as Material synthesis, environmental-protecting performance using plant oleyl alcohol
Face activating agent-modification alcohol ethoxylate surfactant EH, as the key component of cleaning, this surfactant is relative
For widely used primary alcohol ethoxylate and NPE, wetability and detergency are stronger, compound with the moon
Ionic surface active agent and other nonionic surfactants, the efficiency of cleaning is improved, cleaning temperature is reduced to 60 DEG C, it is bright
Aobvious reduces operating power consumption；And by the inspection in actual production, formula is optimized for actual electroplating enterprise
In, there is the advantages of fast cleaning rate, efficiency high, there is preferable cleansing power to different greasy dirts, it is not necessary in disposing waste liquid
Phosphate, simplify treatment process, reduce the usage amount of degreasing powder, reduce cost, reduce the COD of waste liquid, reduce
The characteristic of intractability.Although the advantages of method provided in this article has environmental protection, cost is low and cleaning rate is fast etc.,
There is the alkali of higher concentration in degreasing powder, be not suitable for the pre-treatment of alloy, limit application field, and in use
Substantial amounts of oily waste liquor is inevitably produced, greasy dirt can not be decomposed although the greasy dirt of steel surface can be cleaned, so being
Solve the above problems, also need to make its further modification it to be provided simultaneously with oil removing and decompose greasy dirt function, and expand use
Scope, to meet the cleaning of various section bars.

The 1% of fraction, the bacterium colony that oil degradation speed is fast, colonial morphology is consistent with thalli morphology is retained as purebred；
（3）Polyethylene glycol 2000 is added to the mixing of dimethyl sulfoxide and chloroform that 11-13 is always measured again under the protection of nitrogen
In solution, wherein dimethyl sulfoxide and chloroform are 3 according to volume ratio:1-1.5, appropriate acetic anhydride is added after stirring and dissolving
Acid anhydride stirs 9-11h with 200-300r/min rotating speed at room temperature, and reaction is precipitated after terminating with absolute ether, is subsequently placed in vacuum
Drying at room temperature in drying box；
（4）By three（Methylol）Aminomethane is added to the concentration that 10mmol/L is made in hydrochloric acid solution, and pH is adjusted to 8-8.5, adds
Enter magnetic fluid ultrasonic disperse 30min, dopamine hydrochloride is added after being uniformly dispersed, solid is produced after 2.5-3h is stirred at room temperature
Thing carries out Magneto separate, is dried after repeatedly being washed with absolute ethyl alcohol and deionized water, then according to solid-to-liquid ratio 1:10 are distributed to methanol
In solution, regulation pH value is 4.5-5.5, adds step（3）The product of preparation, tune system pH is 6- after 1h is stirred at 30 DEG C
6.5, continue to stir 1-1.5h, reaction terminates rear magnet separation, and product is washed in neutrality repeatedly with absolute ethyl alcohol and deionized water
Drying for standby afterwards；
（5）By step（2）The strain that aeration domestication obtains is inoculated into beef-protein medium, in 30 DEG C, 150r/min
3h is cultivated on constant temperature oscillator, each bacterial strain is in exponential phase, strain suspension is made, is inoculated into 5% inoculum concentration
In 100ml beef-protein mediums, 1wt% steps are then added（4）The product of preparation, in 30 DEG C of rotating speeds be 160rpm
Reaction 15-18h, is centrifuged off supernatant, lower floor is washed for several times with 0.9% sodium chloride solution, gained immobilized thallus in shaking table
Natural drying at room temperature is standby；
（6）By sodium hydroxide, sodium carbonate, metasilicate pentahydrate sodium and step（5）The product of preparation is stirred 3-5min, adds
Remaining remaining product stirring 5-10min, packaging can obtain compound powder cleaning agent.
