Description
Technical field
The present invention relates to a kind of novel pockmark Pretreatment method of sheet material, especially the pretreatment of ship plate, belongs to boats and ships
Technical field.
Background technology
Hull is all made up of steel plate, and PSPC requires that water soluble salt limits (being equivalent to sodium chloride) 50mg/m2, according to
The regulation of GB/T 18570.9-2005 carries out the mensuration of salinity, and the electrical conductivity measuring steel surface water soluble salt is converted into chlorination
Sodium content.Shipbuilding unit typically to stock up from steel, stack with storage, steeis pretreament, blanking, sectional construction and storage, divide
The aspects such as section construction precision control, the equipment of body section local washing and technique conduct a research, and have carried out stocking up from steel
Whole Process Simulation to delivery, analog result reaches PSPC requirement, and general shipyard, for reaching standard, improves manufacturing process,
Start with from producing design, improve designing quality, coordinate between in-depth specialty, introduce advanced manufacture equipment, improve technological level, carry
High workload efficiency, shortens construction period, accelerates segmentation turnover, makes segmentation be less than one week outdoor standing time as far as possible；Newly-built
The operation area, internal field of 1000 × 250m, by steel material pretreatment until sectional forming all ensures to carry out in indoor, has stopped salt
The rainwater pollution that content is higher, reduces the steel surface salt after sectional forming.Build rain shade to stack temporarily and can not meet turnover
The segmentation required and the segmentation putting construction completion, carry out interim protective measure, to reduce external environment to segmentation salt time inadequate
The impact of part；Substantially it is attained by requirement, but just cannot reach for pockmark plate, but pockmark plate low price, if utilizing
Arrive requirement, the cost of shipbuilding will be substantially reduced, be a urgent problem.
Summary of the invention
It is an object of the invention to provide a kind of novel pockmark Pretreatment method of sheet material.
The problem to be solved in the present invention is the deficiency that existing pockmark plate pretreatment cannot be up to standard.
For realizing the purpose of the present invention, the technical solution used in the present invention is:
A kind of novel pockmark Pretreatment method of sheet material, comprises the following steps
Sheet material is first entered sand washing room by A, carries out derusting by sandblasting；
B places cyclone cluster and pockmark de-burring machine at plate surface, is purged the impurity in pockmark；
C goes up water at plate surface, and sheet material vibrates together with ultrasonic equipment, removes residual impurity；
D high pressure air pressure gun blows plate surface so that it is rapid draing, prevents to get rusty.
Described pockmark de-burring machine includes thimble, movable plate and spring, and thimble is distributed on movable plate, and bottom withstands on pockmark
In, top connects spring, produces variable downforce, along with movable plate moving back and forth on sheet material, and can by thimble not
Break and scrape the removal of impurity in heading into pockmark.
Described thimble bottom is pyramid type, is evenly equipped with 35 altogether.
It is provided with spiral type air channel inside described cyclone cluster so that it is produce whirlwind, strengthens dust removal ability.
Advantages of the present invention: use this technique can remove the impurity in sheet material pockmark very well so that the steel plate of band pockmark
Disclosure satisfy that the requirement of PSPC, the application in later stage also can have the longest service life, reduces shipbuilding cost so that enterprise has
There is the strongest competitiveness, should have market prospect widely.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the present invention is further illustrated.
For the one novel pockmark Pretreatment method of sheet material of ton bulk freighter, comprise the following steps
Sheet material 1 is first entered sand washing room by A, carries out derusting by sandblasting；
B places cyclone cluster 2 and pockmark de-burring machine on sheet material 1 surface, and moves back and forth, and carries out the impurity in pockmark clearly
Remove；
C goes up water on sheet material 1 surface, and sheet material 1 vibrates together with ultrasonic equipment so that impurity departs from steel plate, removes
Residual impurity；
D high pressure air pressure gun blows sheet material 1 surface so that it is rapid draing, prevents to get rusty.
Described pockmark de-burring machine includes thimble 3, movable plate 4 and spring 5, and thimble 3 is distributed on movable plate 4, and bottom withstands on
In pockmark, top connects spring 5, produces variable downforce, along with movable plate 4 moving back and forth on sheet material 1, thimble 3
Constantly enter into back and forth in pockmark, thimble 3 constantly can be scraped the removal of impurity in heading into pockmark.
Described thimble 3 bottom is pyramid type, is evenly equipped with 35 altogether, it is achieved the extensive removal to impurity.
Described cyclone cluster 2 is internal is provided with spiral type air channel so that it is produces whirlwind, similar tornado structure, produces suction, increase
Strong dust removal ability.
By the pockmark steel plate of this technique, the removal of impurity on surface is high, the technique that the steel plate after process has reached PSPC
Requirement, the steel surface grade after now processing should reach the P2 level of regulation in ISO 8501-3:2006, so that the coating selected
Can even spread, reach required NDFT and have enough adhesive force, application leading edge should be processed into radius and be at least 2mm
Fillet, or through three times polishing, or at least through equivalence process so that it is met the requirement of shipbuilding sheet material 1, received ship
The welcome of enterprise.
