Abstract
The descaling agent that a kind of air-conditioning, refrigerating unit heat exchange system are used.Mainly form by mineral acid, inhibitor, washing composition and tensio-active agent.Descaling agent scaling effect of the present invention is remarkable, and is to had no corrosive effect on metals, harmless to HUMAN HEALTH.Behind the snaking, can make the surface form layer protecting film, prevent the coalescent in a large number of grease and incrustation scale, be widely used in the snaking of equipment such as air conditioning machinery, cooler.
Description
The present invention relates to a kind of descaling agent, the descaling agent of particularly a kind of air-conditioning or refrigerating unit.
The heat exchange system of air-conditioning or refrigerating unit can form incrustation scale and greasy dirt on the metal covering of this system after long term operation, cause heat exchanger effectiveness to reduce energy dissipation.At present, the most of employing of the descaling agent of producing both at home and abroad fuming hydrochloric acid, perchloric acid etc. are major ingredient.Though this class descaling agent energy quick descaling is excessive to metal protection, particularly even more serious to corrosion of aluminium alloy.The HCl gas that fuming hydrochloric acid produces when using in addition is harmful to HUMAN HEALTH.
For overcoming the above-mentioned deficiency of existing descaling agent, the purpose of this invention is to provide the quick snaking of a kind of energy, and, HUMAN HEALTH is not had the descaling agent of influence had no corrosive effect on metals.
Descaling agent provided by the invention is formed (weight percent) by following compositions:
1, hydrochloric acid 0-20
2, phosphatase 11 0-20
3, oxalic acid 10-15
4, alkyl imidazoline salt 0-10
5, fatty alcohol-polyoxyethylene ether 0-10
6, sodium sulfate 1-10
7, sea-gull washing composition 0-5
8, deionized water 50-60
The manufacture method of descaling agent of the present invention is: earlier hydrochloric acid, phosphoric acid and oxalic acid are mixed with deionized water, after the dissolving, add alkyl imidazole quinoline salt, fatty alcohol-polyoxyethylene ether, sodium sulfate, sea-gull washing composition again and be heated to 60 ± 2 ℃ promptly.
Descaling agent scaling effect of the present invention is remarkable, and to had no corrosive effect on metals.Owing in the prescription tensio-active agent and washing composition are arranged, therefore described descaling agent has washing and wetting action, can make the surface form layer protecting film behind snaking, to prevent the coalescent in a large number of grease and incrustation scale.
Embodiment 1:
Be grouped into (weight percent) by following one-tenth:
(1), phosphoric acid (industry) 17
(2), oxalic acid 14
(3), alkyl imidazole quinoline salt 5.5
(4), sodium sulfate 3.8
(5), deionized water 59.7
Behind 17kg industrial phosphoric acid and 14kg oxalic acid usefulness 59.7kg deionized water mixed dissolution, add 5.5kg alkyl imidazole quinoline salt and 3.8kg sodium sulfate, be heated to 60 ± 2 ℃ and promptly make descaling agent of the present invention.This prescription is applicable to copper material.
Embodiment 2:
Be grouped into (weight percent) by following one-tenth:
(1), hydrochloric acid (industry) 15.3
(2), phosphoric acid (industry) 14.2
(3), oxalic acid 14.2
(4), fatty alcohol-polyoxyethylene ether 4.1
(5), the sea-gull washing composition 2.5
(6), sodium sulfate 5.2
(7), deionized water 58.7
Behind 15.3kg technical hydrochloric acid, 14.2kg phosphoric acid and 14.2kg phosphoric acid usefulness 58.7kg deionized water mixed dissolution, add 4.1kg fatty alcohol-polyoxyethylene ether, 2.5kg sea-gull washing composition and 5.2kg sodium sulfate, be heated to 60 ± 2 ℃ and promptly get descaling agent of the present invention.This prescription is applicable to the alloy aluminium.
Claims (2)
1, a kind of descaling agent is characterized in that being grouped into (weight percent) by following one-tenth:
(1), hydrochloric acid 0-20

(3), oxalic acid 10-15
(4), alkyl imidazoline salt 0-10
(5), fatty alcohol-polyoxyethylene ether 0-10
(6), sodium sulfate 1-10
(7), sea-gull washing composition 0-5
(8), deionized water 50-60
2, require 1 described descaling agent according to power, it is characterized in that the best proportioning of each composition (weight percent) is:
(1), hydrochloric acid 0-16
(2), phosphatase 11 4-17
(3), oxalic acid 10-14
(4), alkyl imidazoline salt 0-5.5
(5), fatty alcohol-polyoxyethylene ether 0-4.1
(6), sodium sulfate 3.8-5.2
