Izinto ezithile zisetyenziselwa iinkqubo ezithile. Ngokomzekelo, i-galvanized fingerprint material resistant ayikwazi ukusetyenziswa kwinkqubo ye-electrophoretic, eya kubangela ukuba iindawo ze-electrophoretic zikhutshwe. Indlela yokuchonga ngokukhawuleza ukuba kukho isambatho esicacileyo ebusweni bezinto ezinobumba bubuchule obubaluleke kakhulu.
I-passivation, ukuchasana kweminwe kunye nezinye iindlela zonyango emva kokunyanga kukusebenzisa ifilimu engenambala kunye necacileyo emva kokunyanga kwi-substrate ye-galvanized, okunzima ukuyichonga ngokubonakalayo. Zininzi iindlela zokubona ubuchwephesha, kodwa ukufumana indlela enexabiso eliphantsi nesebenzayo yinjongo yethu.
Iindlela zovavanyo zovavanyo lwemichiza
1. Uhlalutyo lwemigaqo
Undoqo weminwe okanye iimveliso ezixhathisayo kukusebenzisa i-organic coating kwi-galvanized substrate. Ngenxa yobukho bokugquma, sinokufumana i-reagent yekhemikhali ephendula kunye ne-zinc layer endaweni yokugquma, kwaye iyahlula ngokomahluko wesantya sokuphendula.
2. Ipropu yovavanyo - i-5% yesisombululo se-copper sulfate
Emva koko, sisungula ngokumangalisayo i-protagonist yalo mbandela: isisombululo se-copper sulfate. Ngokuqinisekileyo, ukuba i-concentration ayiphezulu kakhulu, i-5% yoxinaniso yanele (ingenambala kunye ne-transparent).
3. Ukufunyanwa kunye nesigwebo
Isisombululo se-sulfate yethusi siya kusabela nge-zinc layer (Zn + CuSO4 = ZnSO4 + Cu), ngolu hlobo lulandelayo:
Yehlisa i-5% yesisombululo se-sulfate ye-copper kwi-fingerprint resistant okanye i-passivation resistant product, kwaye uyivumele ime imizuzu emi-3, kwaye isisombululo sisabonakala.
Yehlisa kwiphepha elingagqunyiweyo kwaye uvumele ukuba lime imizuzu emi-3. Isisombululo siphendula kunye ne-zinc layer kwaye ijika ibe mnyama.
imiba efuna ingqalelo
Ngexesha lomsebenzi wokwenene, umphezulu weplate kufuneka ucinywe ngotywala, kungenjalo i-oyile ye-antirust eseleyo iya kulibazisa isantya sokuphendula.
Ibhotile yesisombululo, yehla ngokuhla, imizuzu emi-5, sombulula zonke iingxaki!
Izisombululo zeFauvist
Oku kungasentla sesona sisombululo silula sezemfundo. Okulandelayo yimpahla yokwenyani eyomileyo. Abafundi abangekagqibi ukufunda abanakuyonwabela le nzuzo!
Enyanisweni, uChaige ngokwakhe wasebenzisa indlela elula kwaye ekhawulezayo: indlela yokuxubha iminwe
Emva kokuba ipleyiti yesampulu yosuliwe, sebenzisa iminwe yakho ngamandla kwaye ngokuphindaphindiweyo uhlikihle kumphezulu wepleyiti (ukukhuhlana, njengesantya sikasathana ~ ~).
Iminwe eyenziwe mnyama (kunye ne-zinc powder ewayo) ngamashiti angafakwanga. Ukuba akukho tshintsho olucacileyo phezu komhlaba, lubonisa ukuba kukho i-coating post-coating.
izimvo
Le ndlela idinga amava amancinci, kodwa iyabiza kwaye ininzi. Sifuna ntoni indawo yemveliso? Ngokukhawuleza, kulula, rhabaxa!!!
