Description

一种球墨铸铁管件内衬的防腐工艺
技术领域
本发明属于钢铁产品的制造工艺的技术领域，涉及球墨铸铁管的产品制造技术。更具体地，本发明涉及一种球墨铸铁管件内衬的防腐工艺。
背景技术
在现有技术中，对于球墨铸铁管件内衬的防腐有以下几种技术方案：
1、水泥内衬涂层防腐：这是一种传统的防腐工艺，该工艺操作繁琐，水泥内衬涂层容易产生离鼓、开裂等质量缺陷，该防腐工艺常使用于球墨铸铁管道内防腐。
2、环氧树脂、聚氨酯：该工艺操作繁琐，使用该涂料喷涂之前需要对产品进行抛丸、表面处理、加热、喷涂及固化等工艺环节；原材料使用率较低，成本较高；成品涂层韧性较差，磕碰时涂层易损坏。
3、防腐沥青漆：该防腐工艺虽然成本较低，但不符合环保和卫生的要求。
发明内容
本发明提供一种球墨铸铁管件内衬的防腐工艺，其目的是提高铸管内衬的防腐效果。
为了实现上述目的，本发明采取的技术方案为：
本发明的球墨铸铁管件内衬的防腐工艺，采用的8710防腐涂料；该防腐工艺的方法是：
将配置好的8710防腐涂料采用刷涂、浸涂或喷涂等方式，涂覆在表面干净、干燥的球墨铸铁管件的内表面；
对于堆积的8710防腐涂料要及时修平；
通过多次刷涂、浸涂或喷涂，增加8710防腐涂料的涂层厚度，以达到规定的涂层厚度要求。
在涂覆所述的8710防腐涂料之前，对球墨铸铁管件进行预热处理。
所述的8710防腐涂料分为IPN8710-1防腐涂料和IPN8710-3防腐涂料两种。
所述的IPN8710-1防腐涂料应用于供水管道的内层，即防腐底漆。
所述的IPN8710-3防腐涂料应用于给水管道的外层，即防腐面漆。
本发明采用上述技术方案，操作简便；相比环氧粉末、聚氨酯等原材料使用成本更低，降低制造和使用成本；卫生、环保性能更好；涂层附着力强，铸件的防腐性能更好，提高产品质量。
具体实施方式
下面通过对实施例的描述，对本发明的具体实施方式作进一步详细的说明，以帮助本领域的技术人员对本发明的发明构思、技术方案有更完整、准确和深入的理解。
本发明是一种球墨铸铁管件内衬的防腐工艺，主要是8710涂料对于球墨铸铁管件内衬的防腐应用。为了克服现有技术的缺陷，实现提高铸管内衬的防腐效果的发明目的，本发明采取的技术方案为：
本发明的球墨铸铁管件内衬的防腐工艺，采用的8710防腐涂料；该防腐工艺的方法是：
将配置好的8710防腐涂料采用刷涂、浸涂或喷涂等方式，涂覆在表面干净、干燥的球墨铸铁管件的内表面；
对于堆积的8710防腐涂料要及时修平；
通过多次刷涂、浸涂或喷涂，增加8710防腐涂料的涂层厚度。
8710防腐涂料(即IPN8710防腐涂料)是一种有着化学惰性、耐酸、碱、盐腐蚀且涂膜结构致密，防水渗透性好，附着力强且坚韧丰满的一种供水管道防腐涂料。
为了提高涂层固化速度，在涂覆所述的8710防腐涂料之前，可以对球墨铸铁管件进行预热处理。
所述的8710防腐涂料分为IPN8710-1防腐涂料和IPN8710-3防腐涂料两种。
所述的IPN8710-1防腐涂料应用于供水管道的内层，即防腐底漆。IPN8710-1防腐涂料有着涂膜结构致密，而酸、碱、盐、防锈性能优异、附着力强等特点，所以IPN8710-1防腐涂料一般会应用于供水管道的内层，也就是底漆。
所述的IPN8710-3防腐涂料应用于给水管道的外层，即防腐面漆。而IPN8710-3防腐涂料具有着无毒、抗微生物分包等特点，所以此种IPN8710防腐涂料常应用于给水管道的面漆使用。
使用8710防腐涂料的工艺技术，其操作简便，卫生环保性能好，相比环氧粉末、聚氨酯等原材料使用成本更低，涂层附着力基本能达到6兆帕以上，提高管件内衬的质量，是一种较好的环保卫的防腐涂层。
上面对本发明进行了示例性描述，显然本发明具体实现并不受上述方式的限制，只要采用了本发明的方法构思和技术方案进行的各种非实质性的改进，或未经改进将本发明的构思和技术方案直接应用于其它场合的，均在本发明的保护范围之内。
