Abstract
The invention discloses a technology for spraying a seawater ballast tank, which comprises the following steps of: firstly scouring the surface of an A level steel plate, and spraying base paint; scouring the surface of the steel plate; spraying workshop base paint after treating the surface of the steel plate; after spraying the workshop base paint, machining the structure of the steel plate, and performing second surface treatment; after the second surface treatment, performing first spraying; mainly spraying first-degree bi-component epoxy paint with a spray gun, and performing second pre-spraying after solidifying at 1.5-15 hours; mainly spraying second-degree bi-component epoxy paint with the spray gun; solidifying the steel plate at 5-7 days, and shutting a segmental structure; and repairing shutting places. The technology has convenient operation, greatly prolongs the service life of the seawater ballast tank, and reduces the maintenance cost.
Description
Technical field:
The present invention relates to a kind of technology for spraying seawater ballast tank.
Background technology:
At present, normally used sea water tank spraying coating process, the anticorrosion time limit is generally 3-5, general boats and ships must keep in repair or spraying once more seawater ballast tank after moving 3-5 at sea, the anticorrosion time limit is lower, far can not satisfy the requirement in boats and ships self life-span, and maintenance cost is very high, the waste resource, cost of idleness.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, provide a kind of easy to operate, greatly improved seawater ballast tank service life, lowered the technology for spraying seawater ballast tank of maintenance cost.
Purpose of the present invention is achieved through the following technical solutions: a kind of technology for spraying seawater ballast tank may further comprise the steps:
A, selection grade are that the steel plate of A level carries out surface erosion, primer spray afterwards;
B, the water-soluble salt of use are tested, and are equal to the content≤50mg/m of sodium chloride
2Abrasive material surface of steel plate is washed away processing, reach the Sa2.5 grade after making the roughness of surface of steel plate handle, roughness is between 30-75 μ m, the dust granule size is 1 grade for the dust abundance of " 3 ", " 4 " or " 5 ", promptly amount of dust is few;
C, surface of steel plate are handled back painting workshop priming paint, and priming paint has compatibility with the coating that needs spray;
Behind D, the painting workshop priming paint, the steel plate of selecting in the steps A is carried out steel plate structure processing, carry out the surface treatment second time after structure machines, the same B-C of step closes up weld seam 200mm place without primer spray close simultaneously;
After E, the surface treatment for the second time, use cylinder or brush to carry out the precoating first time;
F, use spray gun main jet first degree bi-component epoxy paint then, solidifies after 1.5-15 hour use cylinder or brush and carry out the precoating second time;
G, re-use spray gun main jet second degree bi-component epoxy paint, total build reaches more than the 320 ц M:
Closing up of H, the 5-7 days laggard body segmental structures of navigating of curing;
I, the place of closing up is repaired the same B of steps in sequence, E, F, G.
The present invention compared with prior art has the following advantages: use technology of the present invention to carry out spraying seawater ballast tank now, the anticorrosion time limit of target at least 15 years in the service life of having improved seawater ballast tank greatly, has lowered maintenance cost.
The specific embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment, and this embodiment only is used to explain the present invention, do not constitute the qualification to protection domain of the present invention.
A kind of specific embodiment of a kind of technology for spraying seawater ballast tank of the present invention, selecting grade is that the steel plate of A level carries out surface erosion, and primer spray afterwards generally is divided into A level or B level according to the surface cleanness of steel plate, the steel plate of A level is cleaner than the steel plate of B level, does not have rust staining substantially; Use water-soluble salt test afterwards, be equal to the content≤50mg/m of sodium chloride
2Abrasive material surface of steel plate is washed away processing, reach the Sa2.5 grade after making the roughness of surface of steel plate handle, roughness is between 30-75 μ m, the dust granule size is 1 grade for the dust abundance of " 3 ", " 4 " or " 5 ", promptly amount of dust is few; Surface of steel plate is handled back painting workshop priming paint, and priming paint has compatibility with the coating that needs spray; Behind the painting workshop priming paint, the steel plate of selecting in the steps A is carried out steel plate structure processing, carry out the surface treatment second time after structure machines, the same B-C of step, close up weld seam 200mm place without primer spray, because segmentation is closed up by welded seam close simultaneously; After the surface treatment for the second time, use cylinder or brush to carry out the precoating first time; Then, use the spray gun main jet first degree bi-component epoxy paint, solidify and use cylinder or brush to carry out the precoating second time after 1.5-15 hour, when temperature was high, hardening time was shorter, and when temperature was hanged down, hardening time was longer; Re-use the spray gun main jet second degree bi-component epoxy paint, total build reaches more than the 320 ц M; To solidify closing up of the 5-7 days laggard body segmental structures of navigating afterwards; At last the place of closing up is repaired the same B of steps in sequence, E, F, G.Use technology of the present invention to carry out spraying seawater ballast tank, the anticorrosion time limit of target at least 15 years in the service life of having improved seawater ballast tank greatly, has lowered maintenance cost.
