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)!

传力接头怎样防腐蚀?

   传力接头怎样防腐蚀?

  传力接头表面防腐涂料的各种性能之间往往是互相矛盾的、互相制约的。传力接头主要作用于水泵与阀门和管道之间的连接,它在管道运行中有一定的多向位移作用,可以缓解管道运行中的盲板推力,对管道起到一定保护作用,特别是对管道的安装和维修提供了很 大的便利。

  当然,这些被牺牲的技术指标在某些特定的应用里往往又上升为决定性的技术指标了。这就要求我们按照不同的使用目的和技术要求来确定传力接头使用的防腐涂料的品种。例如想要配置介质为自来水的传力接头用防腐涂料,应以耐水性的好坏为依据,而对其耐晒性不必过多考虑。反之,暴晒于大气中的设备防腐蚀则不能应用这一品种,否则容易受紫外线光作用而使传力接头表面防腐涂层发生龟裂。

  为了正确地选择传力接头防腐涂料品种,不仅要求我们熟悉各种涂料的特性,而且还要求我们从树脂结构上熟悉各种基团和化学键对传力接头表面涂层性能的影响,以及各种树脂的相溶性和各种颜料对传力接头表面防腐涂料性能的影响。以便视其使用要求而灵活应用,不断研究传力接头表面使用的防腐涂料新品种。
