Kodi mukudziwa njira zochizira mbale ya dzimbiri yachitsulo?

Chitsulo mbaleKomanso kwambiri zosavuta dzimbiri patapita nthawi yaitali, osati kumakhudza kukongola, komanso zimakhudza mtengo wa mbale zitsulo. Makamaka kuchita laser pa mbale padziko zofunika kwambiri okhwima, bola ngati pali dzimbiri mawanga sangathe kupangidwa, nkhani ya mipeni wosweka, mbale pamwamba si lathyathyathya zosavuta kugunda laser kudula mutu. Ndiye tiyenera kuchita chiyani ndi mbale ya dzimbiri yachitsulo?

1. Kutsitsa koyambira pamanja
Zomwe zimatchedwa primitive descaling ndi kubwereka antchito kuti achepetse pamanja. Iyi ndi njira yayitali komanso yovuta. Ngakhale ndondomeko angagwiritsidwe ntchito fosholo, dzanja nyundo ndi zida zina, koma zotsatira za dzimbiri kuchotsa kwenikweni si abwino. Pokhapokha pokhapokha kuchotsa dzimbiri m'dera laling'ono komanso pakalibe njira zina zogwiritsira ntchito njirayi, milandu ina siyikulimbikitsidwa.

2. Mphamvu chida dzimbiri kuchotsa
Kutsika kwa chida champhamvu kumatanthauza kugwiritsa ntchito mpweya woponderezedwa kapena kugwiritsa ntchito njira zoyendetsedwa ndi mphamvu zamagetsi, kuti chida chotsitsa chizitulutsa mozungulira kapena mobwerezabwereza. Mukakumana ndi pamwamba pa mbale yachitsulo, gwiritsani ntchito kukangana kwake ndi zotsatira zake kuchotsa dzimbiri, khungu la okosijeni ndi zina zotero. Kutsika kwachangu ndi mtundu wa chida chamagetsi ndi njira yomwe imagwiritsidwa ntchito kwambiri pakupenta pakali pano.

Mukakumana ndi mvula, chipale chofewa, chifunga kapena chinyezi, pamwamba pazitsulo ziyenera kuphimbidwa ndi primer kuti dzimbiri zisabwerere. Ngati dzimbiri labwereranso musanagwiritse ntchito choyambira, dzimbiri lichotsedwenso ndipo choyambiracho chiyenera kugwiritsidwa ntchito munthawi yake.
3. Kuchotsa dzimbiri pophulitsa
Kutsika kwa ndege kumatanthawuza kugwiritsidwa ntchito kwapakati pa makina a jet pokoka mpweya ndi nsonga ya tsamba kuti atulutse abrasive kuti akwaniritse kuthamanga kwambiri ndikuwonjezera kukangana kuti akwaniritse kutsitsa kwa mbale yachitsulo.

4. Utsi descaling
Utsi descaling njira ndi ntchito wothinikizidwa mpweya adzakhala abrasive pa mkulu liwiro kasinthasintha kupopera pamwamba pa mbale zitsulo, ndi kudzera abrasive zimakhudza ndi mikangano kuchotsa okusayidi khungu, dzimbiri ndi dothi, kuti pamwamba pa mbale zitsulo. kupeza mlingo wina wa roughness, ndi bwino kulimbikitsa adhesion wa utoto filimu.

5. Chemical descaling
Chemical descaling amathanso kutchedwa pickling descaling. Pogwiritsa ntchito njira pickling mu asidi ndi zitsulo oxides anachita, sungunulani zitsulo oxides kuti kuchotsa zitsulo pamwamba oxides ndi dzimbiri.

Pali njira ziwiri za pickling: pickling wamba ndi pickling mokwanira. Pambuyo pickling, n'zosavuta kuti oxidized ndi mpweya, ndipo ayenera passivated kuti kusintha dzimbiri kukana.

Chithandizo cha Passivation chimatanthawuza mbale yachitsulo pambuyo pa pickling, kuti iwonjezere nthawi yobwerera ku dzimbiri, njira yomwe imagwiritsidwa ntchito popanga filimu yoteteza pamwamba pazitsulo, kuti ipititse patsogolo ntchito yake ya dzimbiri.

Malingana ndi momwe zimapangidwira, njira zosiyanasiyana zothandizira zingagwiritsidwe ntchito. Nthawi zambiri mbale yachitsulo iyenera kutsukidwa ndi madzi otentha kuti isalowerere pambuyo pa pickling, ndiyeno imadutsa. Komanso, zitsulo akhoza kutsukidwa ndi madzi mwamsanga pambuyo pickling, ndiyeno kuwonjezera 5% sodium carbonate njira neutralize njira zamchere ndi madzi, ndipo potsiriza passivation mankhwala.

6. Kutentha kwamoto
Kutsika kwamoto kwa mbale yachitsulo kumatanthawuza kugwiritsa ntchito burashi yachitsulo kuchotsa dzimbiri pamwamba pa mbale yachitsulo itatha kutentha pambuyo potentha moto. Musanachotse dzimbiri pamwamba pa mbale yachitsulo, dzimbiri lambiri lomwe limamangiriridwa pamwamba pa chitsulocho liyenera kuchotsedwa musanachotse dzimbiri ndi kutentha kwamoto.
