Abstract

本发明公开一种适用于海底管线清管试压过程中检查泄漏点的染色剂及生产方法，它包括有如下组份及重量份数比：染料0.5~8份；荧光组份0.5~11份；增强溶剂5~16份；清水65~94份；该染色剂是海管清管试压过程中检漏专用药剂，它同时具有染色和荧光两种功能。对白色纯棉指示带的具有很强的染色能力，染色剂中的紫色染料对纯棉指示带有很强的着色能力，一旦吸附就很难洗掉，是检漏功能之一。另一种就是利用该药剂的荧光功能进行检漏，在海底利用灯光照射焊口或法兰连接处上方的海水，如果有漏点，光照射下就会出现绿色荧光或者其它颜色荧光，表明此处有泄漏。

Description

一种染色剂及生产方法
技术领域
本发明属于管道防腐检漏技术领域，具体地说是一种适用于海底管线判定漏点的染色剂及生产方法。
背景技术
在海底管线施工过程中会有焊口及法兰连接处，施工完成后要进行海底管线清管试压操作，清管是清除施工过程中管线内的残留物及管线内壁浮锈，利用投球方法进行；试压是检查管线焊口及法兰连接处是否有泄漏点，因为管线内压力高于管线外部（海洋环境——管线外的海水中），一旦有漏点，检漏剂（染色剂）就会随着管线内海水一起泄漏到海水中，通过指示带和或灯光（白炽灯、LED灯、紫外灯等）就会发现染色剂成份，来判定漏点的。
目前，市场上应用的同类产品一般只具有单一荧光或染色功能，而且其价格也比较昻贵。
发明内容
本发明的目的是提供适用于海底管线判定漏点的染色剂及生产方法。
本发明的目的是通过如下技术方案来实现的：一种适用于海底管线清管试压过程中检查泄漏点的染色剂，它包括有如下组份及重量份数比：染料 0.5 ~ 8份；荧光组份0.5~ 11份；增强溶剂5 ~ 16份；清水65~94份；
所述的染料是指碱性紫（也称品紫，5BN）；荧光组份是指吡唑啉型荧光剂、荧光素钠、香豆素型荧光剂中的一种或两种以上的混合物；增强溶剂是指工业乙醇。
上述染色剂的生产方法是将0.5~8重量份的染料先采用5~16重量份的增强溶剂溶解完全，再与65~94重量份的清水，0.5~11重量份的荧光组份，在合成釜中充分搅拌均匀即为成品。
本发明是通过实验室的大量试验最终研制并生产出染色剂产品，该染色剂是海管清管试压过程中检漏专用药剂，它同时具有染色和荧光两种功能。对白色纯棉指示带的具有很强的染色能力，染色剂中的紫色染料对纯棉指示带有很强的着色能力，一旦吸附就很难洗掉，是检漏功能之一。另一种就是利用该药剂的荧光功能进行检漏，在海底利用灯光照射焊口或法兰连接处上方的海水，如果有漏点，光照射下就会出现绿色荧光或者其它颜色荧光，表明此处有泄漏。
该产品为非危化产品，不燃不爆，运输更安全。无毒，对水环境无污染、使用后可以直接排海，不需要做任何处理，使用操作更简单方便。
