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)!

松套伸缩接头作为管道的柔性衔接

    松套弹性接头作为管道的柔性衔接其意图便是更好的处理管道的仅有问题,例如,冬冷夏热时,管道的热胀冷很明显,管道与管道之间的距离有所改变,更重要的便是管道与管道质之间力的添加。

 

    松套弹性接头*的差异不在表面而是在其内部,由于内部的质量对松套弹性接头的寿数有着很重要的联络。以下是上海骆盈专家为咱们介绍几种较为常见的,简略的区分松套弹性接头原料的物理及化学办法。

    耐介质增重实验:制品取样之后,浸泡在选定介质中,时刻改变限制之后,用调查的办法来断定松套弹性接头的主体质量。100度机油中24小时这个环境下,NBR、氟胶?ECO、CR的质量硬度改变率都是不明显的,而NR、EPDM、SBR都会呈现增重和硬度改变、体积会有胀大焚烧区分法:少数的样品进行实验。

    正常般放在空气里焚烧,然后调查现象。一般的像氟胶、CR、CSM脱离火焰后,不会再持续焚烧,焚烧的火焰也是很 端小的,NR、EPDN这两种的火焰较大。当然在专业店便是气味和色彩以及焚烧时的状况有关了空气老化实验。

    从制品中取样,放在老化箱中老化一度那时刻,调查断定,150度环境下,CR、NR、SBR都会呈现开裂的现象,NBR还会有弹性,180度线一般的NBR会呈现脆断,230度下EPDM会呈现脆断。

    测比重:用电子称和高精度天平,核算他们的比重,例如氟胶的比重会到达1.8以上。而CR、ECO的比重在1.3以上低温断定法:制品取样,干冰和酒精制作低温环境,经过低温环境处理后感觉不同橡胶的软硬度。
