Description
Technical field
It deoils oil/fat composition the present invention relates to one kind.
Background technology
Due to the pollution in iron and steel parts during fabrication used anticorrosive measure, process, surface of steel workpiece
There must be greasy dirt attachment.Mr. Chen Kezhong exists《Metal surface anticorrosive technique》Middle proposition surface of steel workpiece is hung oil mass and be should be less than
Otherwise 0.2g/m2 will influence the generation of phosphating coat, to influence the quality of application, therefore, the processing before steel surface application
In must use degreasing agent removal steel surface greasy dirt.
Degreasing agent, can be divided into dipping degreasing agent, spray degreasing agent by operating method, be wiped degreasing agent etc.；By operation temperature
High temperature degreasing agent can be divided into（80~90 DEG C）, medium temperature degreasing agent（50~70 DEG C）, low temperature degreasing agent（30~50 DEG C）, room temperature degreasing
Agent（10~40 DEG C）；It can be divided into the types such as organic solvent degreasing agent, lotion degreasing agent, chemical degreasing agent by composition.Chemical degreasing
Agent can be divided into water base degreasing agent, acid degreasing agent, alkalilye degreasing agent etc. again.Water base degreasing agent generally by surfactant, alkali, help
The compositions such as lotion the effects that using surfactant etc. to the emulsification, dispersion, solubilising of grease, remove the saponifiability of workpiece surface
With non-saponified property grease；Using the saponification of alkaline matter and saponifiability grease, saponifiability grease not soluble in water is made to become
It can be dissolved in the anion surfactant soap and glycerine of water, saponification is carried out in pH value ＞ 8.5, and temperature is higher, reaction
It is faster；Wherein, alkaline matter includes sodium hydroxide, sodium metasilicate, sodium carbonate etc..
Room temperature water base degreasing agent skimming processes include rolling off process and emulsion dispersion process, and rolling off process depends on degreasing
The physical and chemical activity of surfactant etc. in agent composition weakens or destroys the Adhering capacity or adhewsive action of surface grease,
Degreasing agent molecule enters the interface of metal and greasy dirt, and generates the absorption of orientation here, and grease is made to loosen, from metal watch emaciated face
From；Emulsion dispersion process the effects that due to the emulsifying of surfactant, solubilising, dispersion, is detached from dirt dissolving, the dispersion on surface
In the micella of degreasing, it will not occur and assemble again and be deposited on metallic surface and cause secondary pollution.
It is described acid de- if CN102021591B discloses a kind of acid degreasing agent and preparation method for steel surface
Fat agent phosphoric acid（85%H3PO4）80~120mL/L, i.e. 115~172g/L（100%H3PO4）, 150~200mL of nitric acid（Quality
Concentration 50~70%）, i.e. 98~198g/L；Room temperature or 30~45 DEG C of uses, dosage are 30~50mL/L, i.e. degreasing agent working solution
In contain 3.5~8.6g/LH3PO4,2.9~9.9g/LHNO3.Disadvantage is that：1）Containing body eutrophication can be caused
Two kinds of most important element phosphors, nitrogen, and concentration is higher；2）Room temperature or 30~45 DEG C of uses, when winter temperature is low, not necessarily
Energy degreasing is clean；3）In skimming processes, the greasy dirt on workpiece surface enters degreasing agent, increasingly with the oil concentration in degreasing agent
Height, degreasing efficiency can be lower and lower, when oil concentration reaches certain numerical value, can lose degreasing power, degreasing agent is caused to be scrapped, make
With short life, stock utilization is not high.
CN102433567A discloses a kind of tank leaching type steel room-temperature degreasing agent and its production method, the normal temperature degreasing agent
Sodium tripolyphosphate containing 61~82% sylvite, 1~9%；Working solution is prepared by concentration 5%, impregnates 10~15min at room temperature
Degreasing；CN103668276A discloses a kind of preparation method of efficient degreasing agent, and the efficient degreasing agent contains 300~400g/L
Phosphate, 100~120g/L pyrophosphates；A concentration of 50g/L when use, time are 10~25min, can be removed under normal temperature condition
Remove the antirust oil of steel surface.It is same have as described above containing cause source elements phosphorus, potassium and the degreasing agent of eutrophication with
The shortcomings that oil concentration increases and fails.
Phosphate is classic builder, and still, phosphorus is also to cause one of main element of body eutrophication.Water body
Eutrophication is that the nutriments such as biology required nitrogen, phosphorus and potassium largely enter the slow flow water bodies such as lake, river mouth, bay, causes
Algae and other planktonic organisms breed rapidly, and the dissolved oxygen content in water body declines, and water quality deterioration causes fish and other biological big
Amount is dead or even red tide occurs in thousands of square kilometres of area.So phosphorus can destroy the ecological balance.GB8978-1996《Sewage is comprehensive
Close discharge standard》Regulation, phosphate（In terms of P）Primary standard allows maximal emission to be 0.5mg/L, and secondary standard allows most
A concentration of 1.0mg/L of maximum discharge.Therefore, current development trend is had become using phosphorus-free normal-temperature water base degreasing agent degreasing.
Currently, phosphorus-free normal-temperature water base degreasing agent is disadvantageous in that degreasing agent increases with oil concentration and failed, service life
Short, stock utilization is not high.
