Kodi mukudziwa kusiyana pakati pa blackening ndi black phosphating ya drywall misomali?

Phosphating ndi njira yopangira filimu yotembenuza mankhwala a phosphate pogwiritsa ntchito mankhwala ndi electrochemical reaction, ndipo filimu yotembenuza phosphate imatchedwa filimu ya phosphating. Cholinga chachikulu cha phosphating ndikuteteza zitsulo zoyambira ndikuletsa zitsulo kuti zisawonongeke pamlingo wina; Amagwiritsidwa ntchito poyambira asanapente kuti apititse patsogolo kumamatira ndi kukana kwa dzimbiri kwa filimu ya utoto; Amagwiritsidwa ntchito kuchepetsa kudzoza kwa filimu yamafuta panthawi yachitsulo chozizira.

Phosphating ndi njira yomwe imagwiritsidwa ntchito kwambiri pochiza. M'pofunikanso kuti mankhwala kutembenuka nembanemba mankhwala. Malingana ngati ikugwiritsidwa ntchito ku phosphating yazitsulo zazitsulo, zitsulo zopanda chitsulo monga aluminiyamu ndi zinki zingagwiritsidwe ntchito pa phosphating. Njira yomiza chogwirira ntchito (chitsulo, aluminiyamu, kapena zinki) mu njira ya phosphating (mankhwala ena a acidic phosphate based solutions) ndikuyika filimu yosasunthika ya crystalline phosphate kumtunda imatchedwa phosphating.

Blackening ndi njira yodziwika bwino yochizira kutentha kwachitsulo. Mfundo yake ndi kupanga wosanjikiza filimu okusayidi pa zitsulo pamwamba kudzipatula mpweya ndi kukwaniritsa cholinga kupewa dzimbiri. Pamene zofunikira zowoneka sizikwera, chithandizo chakuda chingagwiritsidwe ntchito. Pamwamba pazitsulo zazitsulo zimakhala zakuda, zina zomwe zimatchedwa buluu. Bluing chithandizo ndi mankhwala pamwamba mankhwala. Ntchito yake yaikulu ndi kupanga wandiweyani okusayidi filimu pamwamba pa workpiece, kupewa dzimbiri ndi dzimbiri, ndi bwino kukana kuvala workpiece. Kuchiza kokha pamwamba sikudzakhudza dongosolo lamkati. Si kutentha mankhwala, ndi kwenikweni osiyana quenching.

Maboti amphamvu kwambiri amagwiritsa ntchito phosphating, yomwe imatha kupewanso zovuta za hydrogen embrittlement. Chifukwa chake, mabawuti opitilira giredi 10.9 m'mafakitale nthawi zambiri amagwiritsa ntchito mankhwala a phosphating pamwamba. Blackening +oiling ndi zokutira zodziwika bwino zamafakitale chifukwa ndizotsika mtengo kwambiri ndipo zimawoneka bwino musanamwe mafuta. Chifukwa chakuda kwake, ilibe mphamvu yoletsa dzimbiri, kotero imachita dzimbiri mwachangu popanda mafuta.

Kuti mudziwe zambiri za misomali yowuma, chonde titumizireni.
