2the five metals constitutional detail outer surface of pistol after to a blasting treatment spray, between spray gun and coated article surface, there is the inclination angle of 18 degree, rifle mouth is 3-18cm to coated article surface distance; First build is 20 ± 5 μ m, after first dry film surface becomes dry, sprays immediately second; Second build is 30 ± 5 μ m, after second dry film surface becomes dry, and Pen tri-roads immediately; San road build is 40 ± 5 μ m, after dry film surface in San road becomes dry, is for further processing;
After d, secondary spray treatment, use clear dope, carry out three moppings; After three moppings, in 2-3 minute, stick diaphragm; Stick after diaphragm, carry out low temperature drying, complete this preservative treatment.
The anticorrosion treatment technology of the five metals constitutional detail of various embodiments of the present invention, owing to mainly comprising: cleaning is carried out in the surface of pending antiseptic five metals constitutional detail; Adopt freezing sand-blasting machine, the outer surface of five metals constitutional detail is carried out to a blasting treatment; After a blasting treatment, use the epoxy zinc-enriched paint of slaking, carry out secondary spray treatment; After secondary spray treatment, use clear dope, carry out three moppings; After three moppings, in 2-3 minute, stick diaphragm; Stick after diaphragm, carry out low temperature drying, complete this preservative treatment.; Can avoid five metals constitutional detail get rusty and affect service life; Thereby can overcome the defect that in prior art, antiseptic power is poor, cost is high and the feature of environmental protection is poor, to realize the advantage that antiseptic power is good, cost is low and the feature of environmental protection is good.
Other features and advantages of the present invention will be set forth in the following description, and, partly from description, become apparent, or understand by implementing the present invention.
Below by embodiment, technical scheme of the present invention is described in further detail.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
According to the embodiment of the present invention, provide a kind of anticorrosion treatment technology of five metals constitutional detail.
The anticorrosion treatment technology of the five metals constitutional detail of the present embodiment, mainly comprises:
A, cleaning is carried out in the surface of pending antiseptic five metals constitutional detail;
B, adopt freezing sand-blasting machine, the outer surface of five metals constitutional detail is carried out to a blasting treatment;
The operation of a described blasting treatment, specifically comprises: adopting compressed air is that power forms high velocity jet bundle, to the five metals constitutional detail outer surface after cleaning, the appearance of five metals constitutional detail outer surface is changed material spray high velocity jet;
After c, a blasting treatment, use the epoxy zinc-enriched paint of slaking, carry out secondary spray treatment;
The operation of described secondary spray treatment, specifically comprises:
With pressure be 1.5-4.5kg/ ㎝
2the five metals constitutional detail outer surface of pistol after to a blasting treatment spray, between spray gun and coated article surface, there is the inclination angle of 18 degree, rifle mouth is 3-18cm to coated article surface distance; First build is 20 ± 5 μ m, after first dry film surface becomes dry, sprays immediately second; Second build is 30 ± 5 μ m, after second dry film surface becomes dry, and Pen tri-roads immediately; San road build is 40 ± 5 μ m, after dry film surface in San road becomes dry, is for further processing;
After d, secondary spray treatment, use clear dope, carry out three moppings; After three moppings, in 2-3 minute, stick diaphragm; Stick after diaphragm, carry out low temperature drying, complete this preservative treatment.
The anticorrosion treatment technology of the five metals constitutional detail of above-described embodiment, cooling water easily corrodes casing and causes getting rusty using, in storage process can to solve existing five metals structure, and rust wadding stops up water inlet pipe and water outlet pipe, causes the technical problem of five metals structure cisco unity malfunction.Like this, by five metals constitutional detail is carried out to preservative treatment, spray suitable anticorrosive paint, avoid water, air and the corrosion of other corrosive liquids to five metals constitutional detail, can ensure that five metals structure normally works.
The anticorrosion treatment technology of the five metals constitutional detail of above-described embodiment, micro-3 DEG C-45 DEG C of construction environment temperature, the micro-8-50% of relative humidity, construction environment cleaning, without dust and greasy dirt.Coating equipment adopts aerial spraying, uses pressurized tank and the domestic PQ-2 type spray gun with agitator when spraying, spray gun bore 1.3-1.9mm, and it is special that equipment is necessary for water-based.The surface treatment of base material: steel structure surface is more than blasting treatment reaches Sa2.5 level, and roughness reaches 18-23 micron; For preventing that steel from getting rusty, in general 3 hours, spray complete.Coating: first component (liquid): component B (powder)=3:7; Ground temperature requirement, higher than 12 DEG C, in stirring first component solution, slowly evenly adds zinc powder, first component solution must not be poured in zinc powder and is stirred; Mixing time 3-8 minute, after having stirred, coating leaves standstill slaking 30 minutes, then coating is stirred and carries out application, as occurs sagging phenomenon, can proper extension curing time and the suitable emulsion ratio that reduces.Application adopts spraying cube formula, and spraying paint film thickness is followed successively by 10 ± 5 μ m, 20 ± 5 μ m, 40 ± 5 μ m; The pressure of whole pressurized tank is 1.5-6kg/ ㎝ 2, pistol is vertical all the time with coated article surface, rifle mouth is 3-18cm to coated article surface distance, adopt wet spray evenly, in the same way, each covering previous 1/4 ~ 1/3, first build is 20 ± 5 μ m, after first surface drying, should spray immediately second, second build is 30 ± 5 μ m, Pen tri-roads immediately after second surface drying, San road build is 40 ± 5 μ m, should shorten the interval time between three road coatings as far as possible, avoids front one coating surface contaminated.Film thickness detects: application was tested to coating layer thickness with boomerang after 20 hours, and the measured value of coating 85% is not less than the build of regulation, and all the other measured values of 15% are not less than 85% of regulation thickness.
When coating thickness measurement, taking steel member as a measuring unit, in especially big component surface, taking 8 ㎡ as a measuring unit, each measuring unit at least should be chosen three place's reference surfaces, and it is 6 mean values of diagonal interleave on 8 × 8cm area that each reference surface is measured.Surface area is less than the member of 1.5 ㎡, measures 5 points, averages.
Finally it should be noted that: the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
