Ntchito yokonzeratu zokutira vacuum makamaka imaphatikizapo njira zotsatirazi, zomwe zimakhala ndi gawo linalake kuti zitsimikizire mtundu ndi zotsatira za zokutira:
No.1 Njira zochiritsiratu
1. Kupera pamwamba ndi kupukuta
Gwiritsani ntchito ma abrasives ndi ma polishing agents kuti mugwiritse ntchito pamwamba pazigawo zopukutidwa kuti muchotse mawonekedwe amtundu wapamtunda ndikukwaniritsa kutsiriza kwina.
Ntchito: Sinthani kumamatira ndi kufananiza kwa zokutira, pangani pamwamba pa zokutira kuti zikhale zosalala komanso zokongola.
2.Kuchepetsa mafuta
Landirani njira zosungunulira zosungunulira, mankhwala kapena ma electrochemical kuchotsa mafuta ndi mafuta pamwamba pazigawo zopukutidwa.
Ntchito: Pewani mafuta ndi mafuta kuti asatulutse thovu, kuwotcha ndi zolakwika zina pakupaka, ndikuwongolera kumamatira kwa zokutira.
3.Kuyeretsa
Gwiritsani ntchito asidi, alkali, solvents ndi zina mankhwala njira kumiza kapena akupanga, plasma kuyeretsa ya yokutidwa mbali kuchotsa pamwamba oxides, dzimbiri ndi zosafunika zina.
Ntchito: kuyeretsanso pamwamba pazigawo zomatidwa, kuonetsetsa kuti zokutira ndi gawo lapansi pakati pa kuphatikiza kwapafupi.
4.Activation chithandizo
Kuwononga padziko yokutidwa mbali mu ofooka asidi kapena njira yapadera kuchotsa passivation wosanjikiza pamwamba ndi kusintha ntchito padziko.
Udindo: kulimbikitsa machitidwe a mankhwala kapena kuphatikiza kwakuthupi pakati pa zinthu zokutira ndi zokutira pamwamba, kukonza kuphatikiza ndi kulimba kwa zokutira.
No.2 udindo wa pretreatment
1. Sinthani khalidwe la zokutira
Kuchiza koyambirira kungathe kuonetsetsa kuti pamwamba pa zigawo zopukutidwa ndi zoyera, zosalala komanso zopanda zonyansa, zomwe zimathandiza kuti yunifolomu iwonetsedwe zazitsulo zowonongeka ndi kuphatikiza kwapafupi.
Izi zimathandiza kukonza ❖ kuyanika kumamatira, kufanana ndi kuuma ndi zizindikiro zina zogwirira ntchito.
2. Konzani ndondomeko yokutira
Njira yopangira pretreatment imatha kusinthidwa molingana ndi zinthu zomwe zidakutidwa komanso zofunikira zokutira kuti zigwirizane ndi njira zosiyanasiyana zokutira ndi zida.
Izi zimathandiza kukhathamiritsa magawo opangira ❖ kuyanika ndikuwongolera zokolola ndi mtundu wa zokutira.
3. Chepetsani zolakwika zokutira
Pretreatment imatha kuchotsa ma oxides, minofu yotayirira, ma burrs ndi zida zina pamwamba pazigawo zopukutidwa, kulepheretsa kuti zidazi zisakhale gwero la zolakwika panthawi yakuphimba.
Izi zimathandiza kuchepetsa thovu, flaking, ming'alu ndi zina zolakwika mu ❖ kuyanika ndondomeko, ndi kusintha aesthetics ndi magwiritsidwe ntchito ❖ kuyanika.
4. Onetsetsani chitetezo chopanga
Masitepe a mafuta ochotsera mafuta ndi kuyeretsa mankhwala pokonzekera mankhwala amatha kuchotsa zinthu zoyaka moto ndi zophulika ndi zinthu zoopsa komanso zovulaza pamwamba pazigawo zowonongeka.
Izi zimathandiza kuchepetsa chiopsezo cha moto, kuphulika kapena kuipitsidwa kwa chilengedwe ndi ngozi zina zachitetezo pakuphimba.
Mwachidule, ntchito yokonzeratu zokutira vacuum imaphatikizapo kupukuta ndi kupukuta pamwamba, kuchotsera mafuta, kuyeretsa mankhwala ndi njira zochiritsira. Chilichonse mwa njirazi chimakhala ndi gawo linalake kuti zitsimikizire ubwino ndi ubwino wa ndondomeko yophimba. Kupyolera mu pretreatment, khalidwe ❖ kuyanika akhoza kusintha, ndondomeko ❖ kuyanika akhoza wokometsedwa, zofooka ❖ kuyanika akhoza kuchepetsedwa ndipo chitetezo kupanga akhoza kutsimikiziridwa.
