Description
Technical field
The present invention relates to plastic tube Removal Technology fields, specially a kind of saving heavy duty detergent PPR pipe road cleaning device for inner wall.
Background technique
PPR pipe, i.e. polypropylene random copolymer pipe are that a kind of have many advantages, such as environment-friendly light, plastics corrosion-resistant, the service life is long
Pipe, is widely used in the fields such as building water supply and drainage and agricultural irrigation, in house decoration, many kitchen sewer water pipelines also all use
Be PPR plastic tube, after long-term use, on the inner wall of pipeline, especially the corner of pipeline, greasy dirt to accumulate over a long period etc. are miscellaneous
Object gradually becomes more, will will lead to line clogging without cleaning.
Since the stable material quality of PPR pipe is higher, the method for chemical reaction can be used to be cleared up, commonly use at present
Saleratus power is cleared up, and suitable saleratus power is poured into sewer, then pour into suitable high concentration vinegar, sodium bicarbonate, that is, carbon
Sour hydrogen sodium, the main component of vinegar are acetic acid, and the two, which mixes, to be chemically reacted, equation CH3COOH+NaHCO3
=CH3COONa+CO2+H2O can generate a large amount of gas and water after reaction, can be washed away the sundries in pipeline using air pressure,
To unclog the pipe, but there is also some problems for this method, i.e. saleratus power during falling from top to bottom, distribution
Be not it is reasonable, the saleratus power amount that often will appear pipeline internal upper part point is more, lower part saleratus power amount is few and inner wall
The situation that upper side saleratus power amount is more, other side saleratus power amount is few, it is undesirable that this will lead to final cleaning effect, needs
It is repeatedly cleared up, can be only achieved preferable cleaning effect using more saleratus power and vinegar, cause unnecessary waste.
