Background technology
Electroceramics spare long-term exposure on converting equipment, the transmitting line is moved out of doors, and its surface can form the comparatively complicated schmutzband of structure owing to be subjected to the pollution of atmospheric environment for a long time.These dirts all are charged usually, along with the accumulation of dirt, strengthen gradually with the adsorptive power on electroceramics spare surface, and density increases gradually, just can influence the insulation effect of electroceramics spare, even causes the generation of pollution flashover accident.
In order to prevent the generation of power system pollution flashover accident, need regularly electroceramics spare to be cleaned.Traditional electroceramics spare purging method is to wipe examination with dry towel, perhaps dips in water with towel and carries out wiping, and general water is to be difficult to the dirt removal on electroceramics spare surface totally, though expended great amount of manpower and material resources, but cleaning performance is very poor.Therefore, just have to electroceramics spare is carried out a large amount of rotating, and the electroceramics spare major part that wheel is changed is eliminated owing to can not thoroughly cleaning up, and has caused serious waste and pollution.Simultaneously, no matter be to clean or electroceramics spare by turns, all need under power down mode, work the many inconvenience that causes life and produce.So, remove the dirt on electroceramics spare surface how time saving and energy savingly, be a difficult problem for a long time for power department.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of and can thoroughly remove electroceramics spare surface dirt, again the multifuctional cleaning agent that can shield to electroceramics spare.
Electrical porcelain piece multifunctional cleaning agent of the present invention is mainly mixed by the component of following parts by weight and forms:
Tetracol phenixin 50~75 ethanol 10~20
Trolamine 10~15 polyvinyl alcohol 5~10
OP emulsifying agent 0.08~0.15 silicon-dioxide 0.05~0.1.
Its preparation method is that each component is placed encloses container in the lump, and the speed stirring with 20~60 rev/mins under the room temperature was made in 5~15 minutes.
Further, the component that also includes following parts by weight in the electrical porcelain piece multifunctional cleaning agent of the present invention:
Silicone oil 1~5 industrial essence 0.1~0.5.
Its preparation method is earlier that silicone oil and OP emulsifier mix is even, places encloses container in the lump with other components, and the speed stirring with 20~60 rev/mins under the room temperature was made in 5~15 minutes.
In each component among the present invention, the trolamine of adding mainly plays infiltration; Polyvinyl alcohol uses as spreader; And the OP emulsifying agent adds as inhibiter, and it can select the OP type emulsifying agent of any model for use; Silicon-dioxide then adds as dispersion agent.
In addition, the purpose that adds silicone oil is that the electroceramics spare surface after the cleaning is protected, and the adding of industrial essence then is a undesired off taste of eliminating electrical porcelain piece multifunctional cleaning agent.
The concrete using method of electrical porcelain piece multifunctional cleaning agent of the present invention is:
1, clean-out system is even according to 1: 4 volume ratio dilute with water, in the watering can of packing into, can the appropriate concentration that increases clean-out system for the electroceramics spare that filth is serious.
2, evenly spray scavenging solution on the electroceramics spare surface that needs clean, keep after 5~6 minutes, with towel with the careful wiping of electroceramics spare one time.
3, with electroceramics spare of watering can flushing that clear water is housed.
4, still unclean as the electroceramics spare after cleaning, can repeat above-mentioned steps 2,3 once more.
Compared with prior art, the present invention has the following advantages:
1, electrical porcelain piece multifunctional cleaning agent of the present invention is main raw material with the tensio-active agent, be equipped with various washing assistants, carry out oleophylic and hydrophilic active material reasonably combined, cleaning performance is good, can peel off and dissolve coagulability dust such as the oil filth such as iron rust, tar on electroceramics spare surface and cement, and other conductive impurities, strong detergency, speed of response is fast, and is more effective than single chemical solvent cleaning.
2, the soil-removing action of electrical porcelain piece multifunctional cleaning agent of the present invention is that wetting, infiltration, emulsification, dispersion, increase-volume by means of tensio-active agent waits and realize, safe, toughened glass surface or glaze to electroceramics spare do not form corrosion, guarantee that the physics and the electric property of electroceramics spare is constant.
3, do not contain ionogen in the electrical porcelain piece multifunctional cleaning agent of the present invention, have volatility preferably, safe in utilization, do not fire not quick-fried, harmless to HUMAN HEALTH, environment is had no adverse effects.
The physicals of using clean-out system of the present invention front and back porcelain bobbin insulator has been carried out mechanical test, the results are shown in following table, as seen used the mechanical property did not influence of clean-out system of the present invention porcelain bobbin insulator.
