Description
Technical field
The invention belongs to metal sample process of surface treatment, be specifically related to the surface anticorrosion technique of a kind of metal sample.
Background technology
In modern industry and daily life, corrosion of metal is seen everywhere, and the especially storage of fuel oil harmful influence is held
The destruction of the forms such as crevice corrosion, stress corrosion and the corrosion fatigue occurred in device, causes great safety for people's lives
Hidden danger.
The metal protection method used at present can be roughly divided into three classes: a class is by anodized, i.e. at metal
Surface forms one layer of tens microns of thick anode oxide film, but owing to anode oxidation process power consumption is big, and electrolyte solution is dirty
Dye is serious, it is difficult to processes, uses its application to be restricted；Equations of The Second Kind is chemical composition coating, will be immersed in necessarily by metal parts
In the solution of composition, rely on chemical reaction to form one layer of chemical composition coating at a certain temperature, the most most widely used be
Chromate chemical aoxidizes, but chromate is a kind of carcinogenic toxicant, and world environments protective tissue has pointed out restriction and uses chromium
Hydrochlorate contains chromate compound with other；3rd class is organic coating, i.e. coats one layer of organic coating in metal surface, to improve
The outward appearance of metal and physical and chemical performance.People start to be used in rare earth element the aseptic technic of metal surface in recent years.
Rare-earth conversion coatings film technique develops into today, and people have carried out a large amount of improvement to various film-forming process, the property of film
Raising can be have also been obtained.At present rare-earth conversion coatings technology is mainly immersion treatment, and this technological operation is simple, be easily maintained；But
Being that its drawback is, long period of soaking process treatment time is oversize, and relatively thin and with base material the adhesive force of the film layer formed is poor.
Summary of the invention
Present invention aims to the deficiencies in the prior art, the gold that a kind of technique is simple, antiseptic effect is good is now provided
Belong to the surface anticorrosion technique of sample.
For solving above-mentioned technical problem, the technical solution used in the present invention is: the surface anticorrosion technique of a kind of metal sample,
Its innovative point is: through defat, the first washing, pickling, the second washing, the 3rd washing, surface conditioner, phosphating process,
4th washing and hot water wash step, completes the surface anticorrosion technique of metal sample；Described specifically comprise the following steps that
(1) defat: the clear water of 700-800L is added in Rinsing Area, is heated up to 40 DEG C；Then by the strong base degreasing agent of 20Kg
Add in Rinsing Area, dissolve while stirring, then will add clear water to 1000L, and be heated up to 55-65 DEG C, metal sample is put into clearly
Tank impregnates 10-15min；
(2) first washings: put in rinsing bowl by the metal sample after defat, are tap water in described rinsing bowl, at normal temperatures
Metal sample after defat is entered in rinsing bowl, impregnate 1min；
(3) pickling: mixed with clear water by hydrochloric acid, prepares pickle, by the metal sample through the first washing often
Impregnating 10-20min under the conditions of temperature in pickle, described concentration of hydrochloric acid is 30%；
(4) second washings: the metal sample after pickling be impregnated under normal temperature condition 1min in tap water；
(5) the 3rd washings: the metal sample after washing second impregnated in 0.5min in tap water under normal temperature condition；
(6) surface conditioner: put in treatment trough by the clear water of 700-800L, uses blender persistently to keep under normal temperature condition
Stirring, adds while stirring by the PL-VMA agent of 3kg in the 60L warm water of 40 DEG C, adds treatment trough after becoming pulpous state；Then
The PL-VMB agent of 3kg is dissolved in the 60L warm water of 40 DEG C, is subsequently adding treatment trough；Finally add clear water to 1000L, at room temperature
Under the conditions of, the metal sample after washing the 3rd impregnated in treatment trough, and described dip time is 1min；
(7) phosphatization: the clear water of 700-800L is added in Phosphating Slot, is subsequently adding the manganese phosphate class overlay film synthetics of 140kg, continues
The continuous clear water that adds, to 1000L, stirs, carries out being warming up to 66-71 DEG C, puts into increasing ferrum thing, takes out and increase ferrum thing, institute after 10min
Stating increasing ferrum thing is steel wool or iron and steel cutting, and in detection Phosphating Slot, the ferrum in liquid divides whether reach 0.5pt, reaches post-heating extremely
93-100 DEG C, above-mentioned metal sample is put into Phosphating Slot dipping 5-15min；
In described detection Phosphating Slot, the ferrum in liquid divides and whether reaches calibration method and be: the liquid that will draw in 10ml Phosphating Slot with suction pipe
Body, in beaker, adds the sulphuric acid of 5ml50% concentration, with the potassinm permanganate of volumetric solution titration 0.18ml, will add sulphuric acid and cross manganese
The medicinal liquid of acid potassium is titrated on potassinm permanganate, presents pinkish, till 10 minutes disappear, then it represents that the ferrum in liquid in Phosphating Slot
Divide up to standard；
(8) the 4th washings: the metal sample after phosphatization is put in tap water washing liquid under normal temperature condition and impregnates, described
The time of dipping is 0.5min；
(9) hot water wash: the metal sample after the 4th washing is put in tap water and carries out dipping washing, described tap water
Temperature is 70-80 DEG C, and described dip time is 0.5min.
Beneficial effects of the present invention is as follows: the present invention is simple to operate, technique is simple, energy-conserving and environment-protective, nontoxic, and leads to
Cross increase surface conditioner and phosphating process, substantially increase the anti-rotten effect of metal sample, add making of metal sample
Use the life-span.
