化工企业经常排出酸性碱性废水,对管道腐蚀严重。过去我们设计酸碱废水管道多采用陶瓷管,但陶瓷管太脆,易破损,不少化工企业的陶瓷管道用不了几年就因破碎堵塞而废弃。近年来,不少化工企业的酸碱废水排水工程设计中采用了硬聚氯乙烯或聚丙烯等塑料管材。塑料管耐腐蚀,又有相当的强度,是用于酸碱废水排水工程中的理想管材。 Chemical companies often discharge acidic alkaline waste water, causing serious corrosion to the pipeline. In the past, we designed ceramic pipes for acid-alkaline waste water pipes. However, ceramic pipes are too brittle and easy to break. Ceramic pipes of many chemical companies will not be used for a few years because they are clogged. In recent years, many chemical companies have adopted plastic pipes such as rigid PVC or polypropylene in their acid-alkali wastewater drainage design. Plastic pipes are resistant to corrosion and have considerable strength. They are ideal pipes for the drainage of acid-alkali waste water.
