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)!

传力接头涂装防腐层时现场温度如何控制

Time:2019/4/4 14:37:17

    限位传力接头涂装防腐层的优点便是可以使其在各种恶劣的环境和不同的介质间运用,那么限位传力接头在涂装防腐层时涂装现场的温度湿度控制在多少范围内呢?限位传力接头在室内进行涂装防腐涂层时温度应控制在20-25摄氏度,相对湿度视限位传力接头的原料的不同而不同,一般以65百分之左右为宜。

 

    在室外施工时,应无风沙、细雨;气温不宜低于5摄氏度,相对湿度不宜大于85百分之。限位传力接头运用的各种防腐涂层的枯燥、固化温度相差很大,一般环氧树脂系涂料在10摄氏度以下固化十分缓慢,故不宜冬天施工。在限位传力接头未透彻固化的涂层上结霜、降露、下雨、砂尘等都是十分有害的,应尽量防止。

    限位传力接头假如合理运用,它的运用寿命能到达十年乃至十年以上,那么在运用过程中答应呈现裂缝吗?它的质量定性规范是什么呢?限位传力接头外壁非工作面答应有宽度不大于1毫米,深度不大于壁厚四分之一,长不超越60毫米的裂缝,但不该多于5处。

    限位传力接头内壁工作面呈现开裂起泡不得多于2个,且起泡直径不大于10毫米,呈现未开裂气泡不得多于3个,且气泡凸起高度不超越壁厚四分之一,直径不大于40毫米;限位传力接头外壁答应呈现直径不大于20毫米开裂气泡3个,未开裂气泡5个。

    限位传力接头内壁工作面答应有直径不大于8毫米,深度不超越壁厚五分之一的岩洞,但不得超越3个,外壁答应呈现2个深度不超越壁厚四分之一,直径不大于15毫米的岩洞。限位传力接头硬度高,但性脆,转移和堆积都应当心轻放,内壁不答应碰伤。
