Abstract

The invention discloses a folding and spraying process of a ship segmented body. The process comprises the following steps: carrying out sandblasting on the ship segmented body; spraying a shop primerwith a thickness of 18-22 micrometers and a width of 148-152 millimeters on a folding port of the ship segmented body; setting apart the shop primer of 148-152 millimeters while spraying a first primer; before spraying a second primer, pasting the edge of the first primer by a masking tape with a width of 48-52 millimeters; then spraying the second primer; and spraying a third primer, a fourth primer and a fifth primer by steps same as that of the second primer. The invention has the advantages of convenient operation, time saving, welding efficiency improvement and secondary corrosion prevention.

Description

The folding and spraying process of ship segmented body

Technical field:

The present invention relates to a kind of folding and spraying process of ship segmented body.

Background technology:

Nowadays, need carry out the streamline preliminary treatment earlier before the folding and spraying of ship segmented body, the seam that closes up with segmented body before exactly ship segmented body being welded together carries out pre-welding treatment, the application shop primer is also wanted secondary rust removal afterwards again, handle the impurity that closes up mouth of segmented body clean, such method is lost time very much, welding quality is lower, and the mouth that closes up of segmented body is corroded the total quality reduction of boats and ships easily once more.

Summary of the invention:

The objective of the invention is in order to overcome above deficiency, provide a kind of easy to operate, save time, improve welding efficiency, prevent the folding and spraying process of the ship segmented body that corrodes once more.

Purpose of the present invention is achieved through the following technical solutions: a kind of folding and spraying process of ship segmented body may further comprise the steps:

A, the ship segmented body is carried out sanding;

After B, sanding are finished, to the shop primer that closes up mouthful spraying 18～22 micron thickness, 148～152 mm wides of segmented body;

C, flow out 148～152 millimeters shop primer during priming paint at spraying first degree;

D, before the spraying second degree priming paint, spend the edge of priming paint with the sticking card first of the U.S. line adhesive tape of 48～52 mm wides;

E, afterwards spray again second the degree priming paint;

F, before spraying the 3rd degree priming paint, spend the edge of priming paint with the sticking card second of the U.S. line adhesive tape of 48～52 mm wides;

G, afterwards spray again the 3rd the degree priming paint;

H, before the fourth priming paint of spraying, spend the edge of priming paint with the sticking card the 3rd of the U.S. line adhesive tape of 48～52 mm wides;

I, spray fourth priming paint more afterwards;

J, before spraying the 5th degree priming paint, glue the edge of obedient fourth priming paint with the U.S. line adhesive tape of 48～52 mm wides;

K, afterwards spray again the 5th the degree priming paint.

The present invention compared with prior art has the following advantages:

1, after sanding is finished,, can save closing up of ship segmented body and segmented body and stitch pre-welding treatment work, improve the quality of welding the shop primer that closes up mouthful spraying 18～22 micron thickness, 148～152 mm wides of segmented body;

2, the edge of segmented body stage each layer of outside plate paint is with the sticking card of the U.S. line adhesive tape of 48～52 mm wides, can obviously tell each layer paint and guarantee the thickness of each layer paint edge.

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 the folding and spraying process of ship segmented body of the present invention may further comprise the steps:

A, the ship segmented body is carried out sanding;

After B, sanding are finished, the shop primer that closes up mouthful spraying 18～22 micron thickness, 148～152 mm wides to segmented body, can save closing up of ship segmented body and segmented body and stitch pre-welding treatment work, improved the quality of welding, prevent that simultaneously corroded once more mouthful position that closes up of segmented body when segmented body from storing, save and close up seam surface in the boats and ships and handle and obtain good processing grade man-hour;

C, flow out 148～152 millimeters shop primer during priming paint at spraying first degree;

D, before the spraying second degree priming paint, spend the edge of priming paint with the sticking card first of the U.S. line adhesive tape of 48～52 mm wides;

E, afterwards spray again second the degree priming paint;

F, before spraying the 3rd degree priming paint, spend the edge of priming paint with the sticking card second of the U.S. line adhesive tape of 48～52 mm wides;

G, afterwards spray again the 3rd the degree priming paint;

H, before the fourth priming paint of spraying, spend the edge of priming paint with the sticking card the 3rd of the U.S. line adhesive tape of 48～52 mm wides;

I, spray fourth priming paint more afterwards;

J, before spraying the 5th degree priming paint, glue the edge of obedient fourth priming paint with the U.S. line adhesive tape of 48～52 mm wides;

K, afterwards spray again the 5th the degree priming paint.

The edge of segmented body stage each layer of outside plate paint is with the sticking card of the U.S. line adhesive tape of 48～52 mm wides, can obviously tell each layer paint and guarantee the thickness of each layer paint edge.
