Pomanga odana ndi dzimbiri pomanga mapaipi amafuta ndi gasi, chithandizo chapamwamba cha chitoliro chachitsulo chowongoka ndi chimodzi mwazinthu zazikulu zomwe zimatsimikizira moyo wautumiki wa payipi yolimbana ndi dzimbiri. Pambuyo pofufuza ndi mabungwe ofufuza akatswiri, moyo wa anti-corrosion wosanjikiza umadalira zinthu monga mtundu wa zokutira, zokutira bwino ndi malo omanga. Zomwe zimafunikira pamwamba pa chitoliro chachitsulo chowongoka zimasinthidwa nthawi zonse, ndipo njira zochizira pamwamba pa chitoliro chachitsulo chowongoka zimasinthidwa mosalekeza. Njira zochotsera zokongoletsa za chitoliro chachitsulo chowongoka makamaka zimaphatikizapo izi:

1. Kuyeretsa
Gwiritsani ntchito zosungunulira ndi emulsions kuyeretsa pamwamba zitsulo kuchotsa mafuta, mafuta, fumbi, lubricant ndi ofanana organic zinthu, koma sangathe kuchotsa dzimbiri, oxide sikelo, kuwotcherera flux, etc. pa zitsulo pamwamba, choncho kokha ntchito ngati wothandiza. amatanthauza mu ntchito zotsutsana ndi dzimbiri.

2. Kutola
Nthawi zambiri, njira ziwiri za pickling mankhwala ndi electrolytic ntchito pickling, ndi pickling mankhwala okha ntchito payipi anticorrosion, amene angathe kuchotsa oxide sikelo, dzimbiri, ndi ❖ kuyanika akale. Ngakhale kutsuka kwa mankhwala kumapangitsa kuti pamwamba pakhale ukhondo komanso kuuma, mawonekedwe ake a nangula ndi osaya ndipo ndikosavuta kuwononga chilengedwe.

3. Chida dzimbiri kuchotsa
Makamaka ntchito zida monga maburashi waya kupukuta pamwamba pa zitsulo, amene angathe kuchotsa lotayirira okusayidi sikelo, dzimbiri, kuwotcherera slag, etc. Kuchotsa dzimbiri kwa zida pamanja kungafikire Sa2 mlingo, ndi kuchotsa dzimbiri zida mphamvu akhoza kufika Sa3 mlingo. Ngati chitsulo chachitsulo chimatsatiridwa ndi chitsulo cholimba cha oxide, mphamvu yochotsa dzimbiri ya zidazo si yabwino, ndipo kuya kwa nangula komwe kumafunika kuti pakhale zomangamanga sikungatheke.

4. Utsi kuchotsa dzimbiri
Jet derusting ndikuyendetsa ma jet kuti azizungulira pa liwiro lalikulu kudzera mu mota yamphamvu kwambiri, kotero kuti ma abrasives monga kuwombera chitsulo, mchenga wachitsulo, zigawo za waya wachitsulo, mchere, ndi zina zotere zimapopera pamwamba pazitsulo zowongoka. chitoliro pansi amphamvu centrifugal mphamvu ya galimoto, amene sangathe kwathunthu kuchotsa oxides , dzimbiri ndi dothi, ndi molunjika msoko zitsulo chitoliro akhoza kukwaniritsa chofunika yunifolomu roughness pansi pa zochita za chiwawa ndi mikangano ya abrasive.

Pambuyo kupopera mbewu mankhwalawa ndi kuchotsa dzimbiri, izo sizingakhoze kuwonjezera adsorption thupi pamwamba pa chitoliro, komanso kumapangitsanso makina adhesion pakati odana ndi dzimbiri wosanjikiza ndi pamwamba pa chitoliro. Chifukwa chake, kupopera kwa jet ndi njira yabwino yochepetsera ma pipeline anticorrosion. Nthawi zambiri, kuphulika kwa mfuti kumagwiritsidwa ntchito kwambiri pochiza mipope yamkati, ndipo kuphulika kumagwiritsidwa ntchito kwambiri pochiza mipope yachitsulo ya msoko.

Popanga, zizindikiro zoyenera zaumisiri zochotsa dzimbiri ziyenera kufunidwa mosamalitsa kuteteza kuwonongeka kwa chitoliro chachitsulo chowongoka chifukwa cha zolakwika zantchito. Embroidery ndi njira yomwe imagwiritsidwa ntchito mobwerezabwereza m'makampani azitsulo.
