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:
Be 0.5-3.0kg/ ㎝ with pressure
2pistol the five metals constitutional detail outer surface after a blasting treatment is sprayed, have the inclination angle of 15 degree between spray gun and coated article surface, rifle mouth is 8-12cm to coated article surface distance; First build is 10 ± 5 μm, after first dry film surface becomes dry, sprays second immediately; Second build is 20 ± 5 μm, after second dry film surface becomes dry, sprays the 3rd road immediately; Second build is 40 ± 5 μm, after second dry film surface becomes dry, sprays the 3rd road immediately;
After d, secondary spray treatment, use varnish, carry out three moppings, after natural drying, namely complete this preservative treatment.
The method for anticorrosion treatment of the five metals constitutional detail of various embodiments of the present invention, owing to mainly comprising: carry out cleaning to the surface of pending antiseptic five metals constitutional detail; Adopt liquid sandblasting machine, a blasting treatment is carried out to the outer surface of five metals constitutional detail; After a blasting treatment, use the epoxy zinc-enriched paint of slaking, carry out secondary spray treatment; After secondary spray treatment, use varnish, carry out three moppings, after natural drying, namely complete this preservative treatment; Five metals constitutional detail can be avoided to get rusty and affect service life; Thus the defect that in prior art, antiseptic power is poor, cost is high and the feature of environmental protection is poor can be overcome, 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 become apparent from description, 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 is only for instruction and explanation of the present invention, is not intended to limit the present invention.
According to the embodiment of the present invention, provide a kind of method for anticorrosion treatment of five metals constitutional detail.
The method for anticorrosion treatment of the five metals constitutional detail of the present embodiment, mainly comprises:
A, cleaning is carried out to the surface of pending antiseptic five metals constitutional detail;
B, employing liquid sandblasting machine, carry out a blasting treatment to the outer surface of five metals constitutional detail;
The operation of a described blasting treatment, specifically comprises: adopt compressed air to be that power forms high velocity jet bundle, by the five metals constitutional detail outer surface after material spray high velocity jet to cleaning, the appearance of five metals constitutional detail outer surface is changed;
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:
Be 0.5-3.0kg/ ㎝ with pressure
2pistol the five metals constitutional detail outer surface after a blasting treatment is sprayed, have the inclination angle of 15 degree between spray gun and coated article surface, rifle mouth is 8-12cm to coated article surface distance; First build is 10 ± 5 μm, after first dry film surface becomes dry, sprays second immediately; Second build is 20 ± 5 μm, after second dry film surface becomes dry, sprays the 3rd road immediately; Second build is 40 ± 5 μm, after second dry film surface becomes dry, sprays the 3rd road immediately;
After d, secondary spray treatment, use varnish, carry out three moppings, after natural drying, namely complete this preservative treatment.
The method for anticorrosion treatment of the five metals constitutional detail of above-described embodiment, can solve existing five metals structure in use, cooling water easily corrodes casing and causes getting rusty in storage process, rust wadding blocking water inlet pipe and water outlet pipe, causes the technical problem of five metals structure cisco unity malfunction.Like this, by carrying out preservative treatment to five metals constitutional detail, spraying suitable anticorrosive paint, avoiding water, air and other corrosive liquids to the corrosion of five metals constitutional detail, can ensure that five metals structure normally works.
The method for anticorrosion treatment 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 is clean, without dust and greasy dirt.Coating equipment adopts aerial spraying, and use the pressurized tank with agitator and domestic PQ-2 type spray gun during spraying, spray gun bore 1.3-1.9mm, it is special that equipment is necessary for water-based.The surface treatment of base material: steel structure surface reaches more than Sa2.5 level through blasting treatment, roughness reaches 18-23 micron; For preventing steel from getting rusty, spray complete in general 3 hours.Coating: first component (liquid): component B (powder)=3:7; Substrate temperature requires higher than 12 DEG C, while stirring first component solution, slowly evenly adds zinc powder, first component solution must not be poured in zinc powder and stir; Mixing time 3-8 minute, after having stirred, coating leaves standstill slaking 30 minutes, then coating is stirred carries out application, as there is sagging phenomenon, can proper extension curing time and suitably reduce emulsion ratio.Application adopts spraying cube formula, and spraying paint film thickness is followed successively by 10 ± 5 μm, 20 ± 5 μm, 40 ± 5 μm; The pressure of whole pressurized tank is 1.5-6kg/ ㎝ 2, pistol is vertical all the time with coated article surface, rifle mouth is 8-12cm to coated article surface distance, adopt wet spray evenly, in the same way, each covering previous 1/4 ~ 1/3, first build is 10 ± 5 μm, second should be sprayed immediately after first surface drying, second build is 20 ± 5 μm, the 3rd road should be sprayed immediately after second surface drying, 3rd road build is 40 ± 5 μm, 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.
During coating thickness measurement, be a measuring unit with steel beam column, especially big component surface is a measuring unit with 8 ㎡, and each measuring unit at least should choose three place's reference surfaces, and each reference surface measures 6 mean values that on i.e. 8 × 8cm area, diagonal is interleaving.Surface area is less than the component of 1.5 ㎡, measures 5 points, averages.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
