冷却塔清洗时使用的中性清洗剂的特征:
The characteristics of neutral detergent used in cooling tower cleaning are:
1、中性清洗无腐蚀:该产品在加入中央空调水系统后不改变水的PH值,对金属无腐蚀损伤,彻底解决了目前普遍使用的强酸性清洗剂对金属的腐蚀隐患,实现了无腐蚀清洗。
1. Neutral cleaning non-corrosive: the product does not change the PH value of the water after joining the central air conditioning water system, no corrosion damage to the metal, completely solved the corrosion hidden danger of the commonly used strong acid cleaning agent to the metal, and realized non-corrosive cleaning.
2、清洗效率高:对各种类型的水垢都有效,尤其对酸洗不净的硫酸盐等难溶垢和藻类生物粘泥也能彻底除去,除垢率95%以上,从而恢复设备原有性能,保持设备清洁运行。
2. Efficiency of cleaning: It is effective for all kinds of scales, especially for insoluble scales such as sulphate and algae bio-slime which can not be cleaned by pickling. The scale removal rate is more than 95%, so as to restore the original performance of the equipment and keep the equipment running cleanly.
3、操作简单:在中央空调正常开机条件下,将中性清洗剂加入水系统运行30天左右将清洗剂排出即可彻底清除水系统内的各种水垢。
3. Simple operation: under the condition of normal start-up of central air conditioning, the neutral cleaning agent is added to the water system to run for about 30 days and the cleaning agent is discharged to completely remove all kinds of scales in the water system.
中性清洗原理:
The principle of neutral cleaning:
根据配位场化学新理论,金属离子的d轨道在某些配位体化合物静电场影响下,可发生分裂而形成能量不同的轨道,当配位体给出孤对电子与中心金属元素形成O健时,若该配位体分子中存在空的π分子轨道或空的p、d分子轨道,且对称性合适,中心元素d轨道上的孤对电了可与配位体形成反馈π键,从而形成稳定的配位化合物。
According to the new theory of coordination field chemistry, the d-orbital of metal ions can split under the influence of the electrostatic field of some ligand compounds to form orbitals of different energies. If the ligand gives a lone pair of electrons to form an O-bond with the central metal element, if there is a hollow pi-orbital or a hollow p, d-orbital in the ligand molecule, The solitary pairs in the central element d orbital can form feedback PI bonds with the ligands, thus forming stable coordination compounds.
基于以上原理,选用能使Ca2+、Mg2+d轨道发生能级分裂且有π分子轨道的化合物作为π接受配位体。当这此化合物与钙、镁水垢作用时,与Ca2+、Mg2+d形成稳定配位化合物,从而破坏了钙、镁水垢的分子结构,将其溶于水中,通过排污除去
Based on the above principle, the compounds which can split the Ca2 +, Mg2 + d orbitals and have the pion molecular orbitals are selected as the acceptance ligands. When this compound reacts with calcium and magnesium scales, it forms stable coordination compounds with Ca2+, Mg2+d, thus destroying the molecular structure of calcium and magnesium scales, dissolving them in water and removing them by sewage discharge.
