Thank you for your attention to ZhongYuan water supply equipment [Knowledge News Information] column! The summer solstice is one of the early confirmed solar terms in the 24 solar terms. In the seventh century BC, the ancestors used Tugui to measure the sun's shadow, and determined the summer solstice. Although the summer solstice indicates that the hot summer has arrived, it is not hot yet. The temperature will continue to rise for a period of time after the summer solstice. It will be hot in about twenty or thirty days. After the summer solstice, the ground is strongly heated and the air convection is vigorous, and thunderstorms often form from afternoon to evening. ZhongYuan remind you Construction of chemical and municipal pipelines in power plants industry customer friends: the weather is hot, pay attention to heatstroke prevention! Thank you for your attention to the Gongyi Zhongyuan Innovation Pipeline Equipment Co., Ltd website (http://ceshi5.66554433.cn)!

钢制伸缩器表面防腐喷漆处理准则

Time:2019/3/21 0:24:34

    涂料的挑选运用决议着钢制伸缩器维护作用的运用寿命但是在涂料种类确认之后,更为重要的是管道的外表处理和施工工艺是否契合不同涂料种类的各自要求由于任何油漆不行能在处理不良的外表上发挥*的成效。

 

    在锈蚀、油渍等杂质沾污的外表上涂装油漆,任何油漆都将在短期内失效。为了确保所用的重防腐涂料能发挥*的维护功能,对钢板的外表处理是很 其重要的,不能在一点点的忽略。

    钢制伸缩器外表的预处理除掉附着于钢板外表的杂质,用稀释剂或清洗剂除掉油脂等尘垢。 如有硫酸盐或腐蚀性盐类,应以清水洗净,以压缩空气吹干。

    在钢材预处理流水线上、铁锈及其他杂质铲除洁净,然后用真空吸尘器或经净化的压缩空气将钢材外表铲除洁净。

    关于预处理的钢材在除锈质量到达要求后,有必要当即涂装一道车间底漆,以防在贮存、安装涂装过程中钢材生锈,并为涂装后道防锈漆维护好钢板的外表。

    抛丸或喷砂处理后的钢材需求除锈质量至少到达Sa2.5级。 选用分段抛丸或喷砂除锈时,在整个分段的除锈质量到达要求后,可直接涂装道防锈漆,而不需求涂装车间底漆。

    涂有底漆的伸缩器外表处理将车间底漆外表的水、湿气、油腻、锈、锌盐及用粉笔或油漆画下的记号和其他尘垢,用清水洗净后再以溶剂擦试洁净。
