The invention relates to the field of ships, and particularly discloses a preparation method of a galvanized steel sheet and a ship applying the galvanized steel sheet. The preparation method of the galvanized steel plate comprises the following steps that S1, a steel plate is subjected to polishing treatment, acid pickling, water washing and plating assistant treatment, and a pretreated steel plate is obtained; s2, the pretreated steel plate is placed in a galvanizing solution at the temperature of 490-530 DEG C to be soaked for galvanizing, then water cooling and drying are conducted, then the pretreated steel plate is placed in a galvanizing solution at the temperature of 490-530 DEG C to be soaked for secondary galvanizing, then the pretreated steel plate is taken out, insulating resin particles are evenly sprayed on the surface of the pretreated steel plate, the insulating resin particles are subjected to hot melting dispersion to form an insulating film, and a semi-finished product is prepared; s3, the semi-finished product is cooled, passivated and dried, and the galvanized steel sheet is obtained; the device is applied to ships. The galvanized steel sheet has the advantages of being insulated, high in strength and not prone to damage under the thunder and lightning condition, and the service life of the ship is prolonged.
本申请涉及船舶领域,具体公开了一种镀锌钢板的制备方法及应用该镀锌钢板的船舶;一种镀锌钢板的制备方法包括如下步骤:S1、将钢板经过打磨处理、酸洗、水洗、助镀剂处理,得到预处理钢板;S2、预处理钢板置于温度490‑530℃的镀锌液中浸泡进行镀锌,然后经水冷、干燥后,再次置于温度490‑530℃的镀锌液中浸泡进行二次镀锌,然后取出预处理钢板,在其表面均匀喷涂绝缘树脂微粒,绝缘树脂微粒热熔分散形成绝缘膜,制得半成品;S3、半成品经过冷却、钝化处理、烘干,得到镀锌钢板;应用在船舶上;镀锌钢板具有绝缘且强度高、在雷电条件下不易受到损坏的优点,延长船舶使用寿命。
