Abstract
The invention discloses a method for purifying waste engine oil containing a phosphating film. The method is characterized in that: a, heating the waste engine oil containing the phosphating film in a purifying cylinder to 120 to 160 DEG C; b, stopping heating, standing, and when the oil temperature naturally drops to 115+/-2 DEG C, slowly adding activated clay with stirring, wherein the activated clay is 2 to 5 percent based on the weight of the waste cold heading oil; and c, standing, when the oil temperature drops to 100 to 180 DEG C, and filtering by a common pressing filter to obtain the finished product of oil. The method for purifying the waste engine oil containing the phosphating film has the advantages of capacity of effectively purifying the waste engine oil, high purification speed of the waste engine oil, low purifying cost, and good purifying effect and has popularization value.
Description
Technical field
The present invention relates to the purifying method of waste oil, more specifically relate to a kind of phosphatize phosphate coat used oil purifying method that contains.
Background technology
When metal wire dispatches from the factory,, usually metal wire has been carried out bonderizing for antirust.Metal wire after utilizing bonderizing pushes, cold-heading molding adds man-hour, needs to use machine oil, usually uses cold-heading oil.Cold-heading oil is formulated by specialist additives such as mineral oil, oiliness toughener, rust-preventive agent, extreme pressure anti-wear additives.Be mainly used in lubricated to the extruding of stainless steel, cold-heading molding complete processing of the cold headers, shaper, heading machine, riveter, rivet driver, threading, forging of all size model.Metal wire push, cold-heading molding adds man-hour, some impurity of the phosphatize phosphate coat of metal wire material surface and metal wire will be dissolved in the machine oil, make machine oil become used oil, at this moment, need be to the used oil processing of regenerating.At present, the used oil purification processing that contains phosphatize phosphate coat is very difficult, and common oil conditioner can't contain the phosphatize phosphate coat used oil and purify processing.So the special process that requires study contains the purification of phosphatize phosphate coat used oil.
Summary of the invention
Purpose of the present invention: a kind of phosphatize phosphate coat used oil purifying method that contains is provided.
Technical scheme of the present invention is:
A kind of phosphatize phosphate coat used oil purifying method that contains is characterized in that its purifying step is:
A. will contain the phosphatize phosphate coat used oil and in purification pot, be warmed to 120-160 ℃;
B. stop to heat, leave standstill, when treating that the oil temperature drops to 115 ± 2 ℃ naturally, slowly add atlapulgite, add the 2-5% of the ratio of atlapulgite, the stirring that does not stop when adding atlapulgite for useless cold-heading oil;
C. leave standstill, when treating the oil temperature, filter, obtain processed oil with common pressure filter to 100-180 ℃.
The above-mentioned described phosphatize phosphate coat used oil that contains is for containing the useless cold-heading oil of phosphatize phosphate coat.
The above-mentioned described phosphatize phosphate coat used oil purifying method that contains will contain the phosphatize phosphate coat used oil and be warmed to 150 ± 2 ℃ for good in purification pot.
The above-mentioned described phosphatize phosphate coat used oil purifying method that contains, the ratio that adds atlapulgite is 3% of a used oil.
Principle of the present invention: iron and steel is after containing phosphatic solution-treated such as zinc, manganese, chromium, iron, form a kind of insoluble phosphate film in base metal surfaces, this kind process is called phosphatization, this film has only several microns usually, main plaing a part strengthens coating and substrate adhesion, and thicker rete can also strengthen rustless property.It is phosphorization agent and Zinc phosphating agent that phosphorization agent generally is divided into iron.Phosphatization is very wide in industrial application, and country has also formulated relevant production technical standard.Atlapulgite has another name called acidic white earth, and it is that natural clay forms after acid treatment, and its main component is a diatomite, and itself is just existing active.The chemical constitution of atlapulgite is SiO
2: (50～70) w%; Al
2O
3: (10～16) w%; Fe
2O
3: (2～4) w%; MgO:(1～6) w% etc.In the atlapulgite adding used oil throwing out takes place, the temperature that improves used oil is exactly in order to improve flocculating effect.
Beneficial effect of the present invention: the phosphatize phosphate coat used oil purifying method that contains of the present invention, can carry out used oil effectively and purify, have the used oil purification speed fast, purify that cost is low, the advantage of good purification, have promotional value.
Embodiment
Below by embodiment, invention is further described.
Embodiment
A kind of phosphatize phosphate coat used oil purifying method that contains, its purifying step is:
A. will contain the phosphatize phosphate coat used oil and in purification pot, be warmed to 150 ± 2 ℃;
B. stop to heat, leave standstill, when treating that the oil temperature drops to 115 ± 2 ℃ naturally, slowly add atlapulgite, the ratio that adds atlapulgite is 3% of useless cold-heading oil, the stirring that does not stop when adding atlapulgite;
When c. oily temperature being warmed to 130 ± 2 ℃, filter, obtain processed oil with common pressure filter.The machine oil that the extruding of steel, cold-heading processing are used, the high speed multi-station cold-heading oil that adopts Shanghai petroleum goods Applied Research Laboratory to produce is good.
