Cov txheej txheem ntxuav tseem ceeb rau cov dej kub hauv tsev muaj xws li hauv qab no:
1. Mechanical Descaling
Taw qhia: Haum rau me me cam khwb cia hlau dej kub boilers, tshwj xeeb tshaj yog thaum muaj xoob scale thiab slag nyob rau hauv lub boiler.
Cov kauj ruam: Tom qab kaw lub boiler, txias nws, ntws lub boiler dej, yaug nrog dej huv, thiab ces siv ib tug ca chisel, hlau txhuam, los yog motorized milling tshuab rau lub cev descaling.
2. Acid ntxuav
Taw qhia: Siv cov kua qaub uas muaj cov tshuaj hydrochloric acid lossis nitric acid thiab cov tshuaj tiv thaiv corrosion, txoj kev no tshem tawm cov nplai ntawm lub boiler thaum txo qis corrosion.
Cov kauj ruam: Npaj cov kua qaub, txhaj rau hauv lub boiler, thiab ntxuav raws li lub sijhawm tu thiab qhov kub thiab txias. Tom qab ntxuav, yaug kom huv si nrog dej huv.
3. Alkaline Descaling
Taw qhia: Txawm hais tias cov nyhuv descaling tsawg dua li cov kua qaub ntxuav, nws yooj yim rau kev khiav lag luam, muaj kev phiv tsawg dua, thiab tsim nyog rau ua ntej - kho cov nplai uas nyuaj rau tshem tawm nrog hydrochloric acid.
Cov kauj ruam: Npaj cov alkaline boiling tov, txhaj cov alkaline boiling tov rau hauv boiler, sov nws mus rau lub teev kub thiab tswj nws rau ib lub sij hawm ntawm lub sij hawm kom loosen lub teev, thiab ces yaug nws.
