Description
技术领域
本发明涉及化工技术领域,尤其涉及一种中央空调冷媒水超分子缓蚀阻垢剂及其使用方法。
背景技术
目前,中央空调应用越来越普遍,其冷媒水***运行状况很大程度上决定致冷、致热效果。中央空调冷媒水***主要包括冷却水***和冷媒水***,其中冷媒水***更是直接影响空调使用效果。冷媒水***是以水做冷媒介质和空气进行能量交换的密闭式体系,虽然与外界接触较少,但在整个体系的最高处设有膨胀水箱,这样冷媒水介质还是和空气有所接触,使溶解氧和一些营养物进入冷媒水***,加上冷媒水原来的溶解氧,产生氧腐蚀和电化学腐蚀,腐蚀产生的污垢沉积,不仅影响传热,还能加速氧浓差电化学腐蚀,严重的会引起设备的穿孔泄露。中国专利号201610010685.7公开了一种中央空调节能护理剂,并公开了护理剂的具体组份,其中,结垢并清理混在冷媒水流动过程中,护理剂中的高精细石墨粉用于润滑冷媒水中的结垢,避免流动不畅。但是,在实际使用过程中,由于采用高精细石墨粉无法溶于水,高精细石墨粉容易覆盖在形成有结垢的冷媒水***的金属表面,结垢被高精细石墨粉覆盖住造成护理剂无法快速有效的清理结垢,从而无法在冷媒水***的金属表面形成完整的超分子保护膜,导致中央空调冷媒水***的清洁效率和效果较差。如何设计一种中央空调冷媒水***清洁效率和效果更好的清洁剂是本发明所要解决的技术问题。
发明内容
本发明所要解决的技术问题是:提供一种中央空调冷媒水超分子缓蚀阻垢剂及其使用方法,通过向冷媒水中添加超分子缓蚀阻垢剂,实现提高中央空调冷媒水***清洁效率和效果。
本发明提供的技术方案是,一种超分子缓蚀阻垢剂,包括以下重量百分比的组分:脂肪醇聚氧乙烯醚4%~6%、十二烷基二甲基苄基氯化铵5%~10%、苯丙三氮唑4%-6%、氰基乙酸4%~5%、直链烷基磺酸钠盐1%~1.5%、乙二醇2%~3%、盐酸吡哆醇1%~1.5%、磷酸氢二钠2%~2.5%,余量为水。
进一步的,还包括:多聚氧化乙烯壬酚醚3%~6%、对甲苯胺4%~5%、乙二胺三乙酸1%-1.5%。
进一步的,还包括:硅钾酸2%-3%、聚丙烯酸2%-2.5%、十二烷基二甲基苄基氯化铵磷酸氢二钠0.5%-1%、二羟乙基高碳脂肪酰胺0.5%-1%、烷基苯磺酸0.3%-0.8%、二甲基苯磺酸钠1.2%-1.5%。
进一步的,还包括:焦磷酸四钾3%-5%。
本发明还提供一种中央空调冷媒水超分子缓蚀阻垢剂的使用方法,所述中央空调冷媒水超分子缓蚀阻垢剂采用上述中央空调冷媒水超分子缓蚀阻垢剂;其中,中央空调中的冷媒水的加注量为L;使用方法为:直接向中央空调的冷媒水中投放0.1L加注量的中央空调冷媒水超分子缓蚀阻垢剂,中央空调运行3-5天后,从中央空调的排污管取水样观察,如果冷媒水变成深棕色或黑色,则中央空调把冷媒水排净,更换新的冷媒水并再次投加0.05L加注量的中央空调冷媒水超分子缓蚀阻垢剂,如果冷媒水是淡色或浅棕色,则不需换水加药,中央空调直接运行即可。
与现有技术相比,本发明的优点和积极效果是:本发明提供的中央空调冷媒水超分子缓蚀阻垢剂,通过在超分子缓蚀阻垢剂中添加脂肪醇聚氧乙烯醚、十二烷基二甲基苄基氯化铵可以清洗金属表面的铁锈,并对难溶垢进行初步冲洗,而苯丙三氮唑进行缓蚀确保清洗剂防腐蚀性能,不对金属本身造成伤害;重要的是,采用乙二醇和盐酸吡哆醇配合磷酸氢二钠来替代难溶解的石墨粉,磷酸氢二钠溶于水不溶于醇,而乙二醇和盐酸吡哆醇又溶于水中以形成具有润滑作用的液体,混在冷媒水中的结垢能够顺畅的流动;氰基乙酸具有催化作用,加速直链烷基磺酸钠盐等组分协调组装,结合成复杂有组织的聚合体,在金属表面形成一层超分子膜达到延缓结垢的效果,通过向供热冷媒水中添加超分子缓蚀阻垢剂,实现提高中央空调冷媒水***清洁效率和效果,达到零腐蚀、零结垢、零排污的效果。
具体实施方式
本发明提供一种用于中央空调冷媒水用的超分子缓蚀阻垢剂,该超分子缓蚀阻垢剂包括以下重量百分比的组分:脂肪醇聚氧乙烯醚4%~6%、十二烷基二甲基苄基氯化铵5%~10%、苯丙三氮唑4%-6%、氰基乙酸4%~5%、直链烷基磺酸钠盐1%~1.5%、乙二醇2%~3%、盐酸吡哆醇1%~1.5%、磷酸氢二钠2%~2.5%,余量为水。
具体而言,通过超分子缓蚀阻垢剂中的脂肪醇聚氧乙烯醚配合十二烷基二甲基苄基氯化铵可以清洗金属表面的铁锈,对水垢进行吸附和分解,并对难溶垢进行初步冲洗,而苯丙三氮唑进行缓蚀确保清洗剂防腐蚀性能,不对金属本身造成伤害;同时,配合氰基乙酸的催化作用下,能够加速磷直链烷基磺酸钠盐等组分协调组装,再将金属表面各种铁锈、水垢、泥垢等污物清除后,在金属表面组成一层超分子膜,达到缓蚀阻垢的作用。重要的是,采用乙二醇和盐酸吡哆醇配合磷酸氢二钠来替代难溶解的石墨粉,磷酸氢二钠溶于水不溶于醇,而乙二醇和盐酸吡哆醇又溶于水中以形成具有润滑作用的液体,混在冷媒水中的结垢能够顺畅的流动。
进一步的,超分子缓蚀阻垢剂还包括:多聚氧化乙烯壬酚醚3%~6%、对甲苯胺4%~5%、乙二胺三乙酸1%-1.5%。具体的,增加的多聚氧化乙烯壬酚醚与对甲苯胺反应后可以具备良好的化学稳定性,具有理想的协同效应,对许多金属离子如钙、镁、铜等具有优异的螯合能力,提高其抗结垢性能和缓蚀能力;而增加的乙二胺三乙酸对供热冷媒水形成的闭式循环流路中的污垢进行吸附、粘结和分解,从而无需排放废水,还能够阻止水中的溶解氧与金属表面接触腐蚀金属,达到相关设备零腐蚀、零结垢和零排污的目的。优选的,超分子缓蚀阻垢剂还包括:硅钾酸2%-3%、聚丙烯酸2%-2.5%、十二烷基二甲基苄基氯化铵磷酸氢二钠0.5%-1%、二羟乙基高碳脂肪酰胺0.5%-1%、烷基苯磺酸0.3%-0.8%、二甲基苯磺酸钠1.2%-1.5%。具体的,硅钾酸和聚丙烯酸能与冷媒水中的金属离子形成稳定的化合物,对水中的碳酸钙和氢氧化钙有优良的分解作用,从而可以更有效的分解金属表面上形成的结垢,同时,也有利于减缓结垢的形成;而十二烷基二甲基苄基氯化铵磷酸氢二钠、二羟乙基高碳脂肪酰胺、烷基苯磺酸、二甲基苯磺酸钠将进一步的起到组分协同的作用,更有利于实现超分子自组装,满足高温环境下在金属表面形成一层超分子膜达到延缓结垢的效果。另外,超分子缓蚀阻垢剂还包括:焦磷酸四钾3%-5%,焦磷酸四钾可以软化硬水、提高清洗能力、清除污垢,与脂肪醇聚氧乙烯醚和十二烷基二甲基苄基氯化铵协同作用,实现更加全面有效的清除结垢。
最后应说明的是:以上实施例仅用以说明本发明的技术方案,而非对其限制;尽管参照前述实施例对本发明进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
