Description
技术领域
本发明属于化工产品技术领域,特别涉及SQ-924高效粘泥剥离剂。
背景技术
在工业用水和民用水中,水体富营养化已成为制约水利用的主要因素之一。细菌和藻类的过度繁殖严重影响水体的功能,一方面污染输水管线,堵塞滤池,造成供水事故;另一方面,会造成水体发臭,影响景观。在工业上,则会造成生物粘泥堵塞换热设备、腐蚀金属,影响工厂的安全生产。因此,对细菌和藻类的控制成为水质的主要水质恶化;此外在工业冷却水的处理中,经常遇到腐蚀、结垢、粘泥问题。随着水处理技术的提高,大部分冷却水的缓蚀、阻垢问题得到了较好的解决,但系统的粘泥和菌藻问题较突出,特别在物料泄漏的情况下,粘泥往往剥离不好。微生物粘泥一旦大量形成,不仅会降低换热器和冷却塔的冷却作用、恶化水质,而且还会引起冷却水系统中设备的腐蚀和降低水质稳定剂的缓蚀、阻垢和杀生作用,直接影响并危害生产,带来经济损失。
目前,工业中使用的粘泥剥离杀菌剂大多是由杀菌剂、表面活性剂、渗透剂、有机溶剂等复配而成,其不但使用起来比较繁琐成本高而且稳定性较差,杀菌与剥离性能也不理想。由于有机溶剂的使用,增加了VOC有机挥发组分,不仅给系统使用环境带来隐患,也影响了操作者的健康状况;此外不容易讲解,污染水体。
目前的粘泥剥离杀菌剂制备工艺比较繁琐,副产物较多、反应步骤较多、反应时间较长,也在一定程度上增加了企业的成本。
发明内容
本发明提供SQ-924高效粘泥剥离剂,可以解决背景技术中所指出的问题。
SQ-924高效粘泥剥离剂,其特征是该SQ-924高效粘泥剥离剂由以下组分按重量比配制而成:环氧氯丙烷10-30份、水5-20份、十二烷基叔胺10-40份、二甲胺10-50份;
非氧化性杀菌剂1-2份、稳定剂0.1-0.2份、非离子表面活性剂1-3份。
作为优选的,非氧化性杀菌剂为异噻唑啉酮,所述稳定剂为硫酸铜或溴化钠,所述非离子表面活性剂为烷基酚聚氧乙烯醚类非离子表面活性剂。
一种生产上述SQ-924高效粘泥剥离剂的方法,包括以下步骤:
步骤1、将环氧氯丙烷10-30份、水5-20份、十二烷基叔胺10-40份,依次抽入反应釜釜底,开动搅拌,高位槽1内抽入10-50分二甲胺,高位槽2内加入1-10份水;30-40分钟后打开冷凝器,待反应釜内升温50-80℃,预反应10-30分钟,降温至30-50℃;开始匀速滴加二甲胺,控温50-80℃以下,滴加6—9小时;滴加完毕,高位槽2加入反应釜内1~10份水,冲洗管路,釜内升温50-80℃,继续反应2-6小时;降温至30-50℃,停止搅拌5-20分钟后,加水稀释,搅拌10-20分钟,过滤放料,即得本产品的主剂;
步骤2:将步骤1中得到的主剂与非氧化性杀菌剂1-2份进行复配,搅拌后加入稳定剂0.1-0.2份、非离子表面活性剂1-3份,搅拌均匀后即得本产品。
在本发明中,步骤1能得到纯度较高的主剂,反应的转化率也比较高,复配过程中加入的异噻唑啉酮属于高效杀菌剂,异噻唑啉酮是通过断开细菌和藻类蛋白质的键而起杀生作用的。异噻唑啉酮与微生物接触后,能迅速地不可逆地抑制其生长,从而导致微生物细胞的死亡,故对常见细菌、真菌和藻类等具有很强的抑制和杀灭作用,同时异噻唑啉酮可以是MIT和CMIT的一种物质或者混合物质;为了防止非氧化性杀菌剂沉淀,异噻唑啉酮里加入稳定剂,稳定剂为硫酸铜或溴化钠,溴化钠,溴化钠复配后产品为无色,硫酸铜稳定剂会使产品成淡蓝色。可以根据使用的环境选择合适的稳定剂;烷基酚聚氧乙烯醚类非离子表面活性剂可以增强产品的黏泥剥离效果,烷基酚聚氧乙烯醚类非离子表面活性剂可以为辛基酚聚氧乙烯醚或壬基酚聚氧乙烯醚。
本发明提供SQ-924高效粘泥剥离剂,杀菌效果优异、广域性、阈值低。对好氧细菌及异养菌均有较强的杀灭效果,还具有优良的剥离去除设备、管道内壁附着的黏泥以及微生物尸体功能,同时还可杀灭循环水系统中的各种细菌、真菌及藻类,可广泛用于循环冷却水处理领域,本发明一剂多效兼具杀菌粘泥剥离,且生物易降解、不污染水体。
此外生产SQ-924高效粘泥剥离剂的方法工艺比较简单,反应的步骤较少,反应时间较短,可以节省劳动时间和劳动成本。
