Description
Technical field
The present invention relates to a kind of without phosphorus degreasing powder, particularly a kind of low COD (Chemical Oxygen Demand), low bubble
Without phosphorus degreasing powder.
Background technology
Degreasing powder is to apply a kind of quite varied chemicals, custom in hardware, plastic cement plating, the preceding processing of spraying industry
Name skimmed milk.It is also used for various hardware cleaning industries, and electrochemical deoiling powder and electrolytic degreasing powder can be divided into by cleaning way.Remove
Oil-bound distemper is to use the refined low bubble oil removing degreasing agents such as a variety of high-quality surfactants, detergent, bleeding agent, builder,
With abilities such as good wetting, emulsifications, there is stronger ability of deoiling.Workpiece surface after cleaning is without visible oil film or oil mark.
The cleaning of the various types of materials such as aluminium alloy, kirsite, magnesium alloy, steel and iron parts, stainless steel is can be applied to, to workpiece not damaged phenomenon.
Phosphate has stronger sequestering, can be widely used as builder in degreasing powder.However, phosphate
The presence of middle P elements easily causes body eutrophication, and finally water body is polluted.
Although the without phosphorus degreasing powder applied in current industry has also reached low-phosphorous requirement, strong chelating agent generation is employed
For phosphate, it is unfavorable for biodegradation, there are COD height, the high two large problems of foam.It can cause working solution as excess foam rises
Overflow, not only result in material waste, improve cleaning cost, it is also possible to produce spot on cleaning workpiece surface, give production band
It is inconvenient to come.Excessive foam will also hinder the flushing of greasy dirt and slow down precipitation and the separation of dirt, during discharge degreaser due to
Foam excessively can also aggravate environmental pollution.

Nonionic surfactant and 5% anion surfactant.
In preferred embodiments, maleic acid/acrylic acid of the dispersant selected from molecular weight 10000 to 70000 is common
Polymers, the maleic acid homopolymer of molecular weight 2000 to 8000, and combinations thereof.
In preferred embodiments, the nonionic surfactant is modified fatty alcohol polyethenoxy polyethenoxy ether
Class, for example, V-27 (CAS:68603-25-8)、SKYN2524.
In preferred embodiments, the anion surfactant is selected from modified polycarboxylic acid salt, modified polyether class
And combinations thereof, for example, AKYPO LF4, Sokalan CP-9, L44 or DSP-60.
The present invention use modified fatty alcohol polyethenoxy polyoxypropylene ethers nonionic surfactant (its molecular formula for
C12H30O2) it is combined that there is provided a kind of without phosphorus degreasing powder with modified polycarboxylic acid salt analog anion surfactants.The present invention's
Without phosphorus degreasing powder oil removing is quick, washing performance is good, and any defoamer and strong chelating agent, product foam pole are not used in product
Low, COD is low, and can fast degraded biologically.
Embodiment
The instantiation of without phosphorus degreasing powder of the invention presented below is come to being expanded on further the present invention.
Example 1：
Example 2：
Example 3：
According to the conventional detection method of this area, the detection of multiple projects is carried out to the without phosphorus degreasing powder of the present invention, as a result
It see the table below：
Compared with existing without phosphorus degreasing powder, without phosphorus degreasing powder of the invention especially has advantages below：
Existing without phosphorus degreasing powder uses strong chelating agent, is unfavorable for the wastewater treatment after cleaning, offer of the invention it is without phosphorus
Potent chelating agent is not used in degreasing powder, it is easy to biodegradable；
Existing without phosphorus degreasing powder foam is high, needs to rinse ability thoroughly cleaning totally with a large amount of water after cleaning, water consumption is big, this
