Ensimini yokusebenza kwensimbi eshidi, ukwelashwa okungaphezulu akukuthinta kuphela ukubukeka komkhiqizo, kepha futhi kuhlobene ngokuqondile nokuqina kwawo, ukusebenza kanye nokuncintisana kwemakethe. Noma ngabe isetshenziswa emishini yezimboni, ukukhiqiza izimoto, noma izinto ze-elekthronikhi, izinqubo zokwelashwa ezisezingeni eliphakeme zingathuthukisa kakhulu ikhwalithi yomkhiqizo nenani elingeziwe. Amathiphu alandelayo alandelayo angu-10 enzelwe ukukusiza uthuthukise ukugeleza kwenqubo ye-Sheet Surbel Surce Survate Treatment Treatment and Treat Surface Surface Surface Surface Surface Surface Surface Surface Surface Surface Surface Surface Surface Surface Surface Surface Surface Surface Surface Surface Surface Surpace Surface Surface Surface Surface Surface Surpace Surface Surce Ource
Ithiphu 1: Ukwelashwa okunembile kwangaphambili
Ngaphambi kokuthi kuqale noma iyiphi inqubo yokwelashwa engaphezulu, ukuncipha okuphelele komhlaba kuyisisekelo sokuqinisekisa umphumela wokwelashwa okulandelayo.
Ukususa uwoyela ongaphezulu, ama-oxides nokugqwala kuwumsebenzi wokuqala. Ungasebenzisa ama-degreasers abuchwepheshe noma ukususa ukugqwala, okuhlanganiswe nokufaka, ukufafaza noma ukusula kwencwajana.
Ngokungcola ngenkani, ukugaya okwenziwe ngomshini (njenge-sandpaper, isondo lokugaya, njll.) Lingasetshenziswa.
Naka lapho kusebenza:Lawula amandla ukugwema ukulimaza indawo engaphansi, ikakhulukazi izingxenye zensimbi ezishibeni ezincanyana.
Iziphakamiso Zokuthuthuka: Sebenzisa imishini yokuhlekisa ezenzakalelayo (efana namasistimu wokufafaza) ukuqinisekisa ukusebenza kahle nokuvumelana, ikakhulukazi ekukhiqizeni inqwaba.
ICEBISO 2: Khetha impahla efanelekile yokuhlanganisa
Izimo ezihlukile zokusebenzisa zinezidingo ezihlukile zezinto zokwenza izinto zensimbi yensimbi:
Imvelo yangaphandle: Kunconywa ukusebenzisa ukunamathela ngokumelana nesimo sezulu esiphakeme, njengokuhlanganiswa kwe-fluorocarbon noma i-acrylic coating.
Izingxenye eziphakeme zokuphambana: I-Polyurethane Coating noma i-Ceramic Coatic icatshangelwa ukwandisa ukumelana kokugqoka.
Ngasikhathi sinye, ukunakwa kufanele futhi kukhokhelwe ekunamathisweni kwe-coating, engathuthukiswa yi-primer. Ngezimo ezikhethekile zesidingo (ezinjengezindawo ze-antibacterial noma zokufaka inyusa), kubhekwa izigqoko ezisebenzayo.
Amathiphu:Ubungane bezemvelo kanye ne-Voc ephansi (i-veratile organic compound) okuqukethwe kwezinto zokwenza ama-coating kuba yindawo yemakethe, nezingubo eziluhlaza nezemvelo zingakhethwa.
Ithiphu 3: Lungiselela amapharamitha wenqubo yokufafaza
Amapharamitha wenqubo yokufafaza ngokuqondile anqume ikhwalithi nokubukeka kwe-coating:
Ibanga lesibhamu lokufafaza: kufanele ligcinwe phakathi kuka-15-25 cm ukugwema izinhlayiya ze-sagging noma ezihlanganayo.
Ukufafaza ingcindezi: Kunconywa ukuba ube phakathi kuka-0.3-0.6 MPA ukuqinisekisa ukuphuma kwe-atomization efanayo kapende.
Ukufafaza ijubane ne-angle: Ngezisebenzi zomsebenzi ezinobukhulu obuyinkimbinkimbi, lungisa i-angle yesibhamu sokufafaza ukuqinisekisa ukubekelwa okufanayo okuhlanganisiwe emaphethelweni nasemigomweni.
Iziphakamiso Zokuthuthuka:Yenza izivivinyo zesampula zesampula ngesikhathi sesigaba sokuqinisekiswa kwenqubo ukuze uthuthukise izilungiselelo zepharamitha futhi uqinisekise ukuqina ekukhiqizweni okukhulu.
Ithiphu 4: Sebenzisa ubuchwepheshe bokufafaza nge-electrostatic
Ukufafaza nge-electrostatic sekuyisinqumo sokuqala ukwelashwa kwanamuhla komhlaba ngenxa yezinga lazo eliphakeme nokufana:
Umphumela ophansi uyisihluthulelo sekhwalithi yokufafaza, kanye nemishini enesisekelo yobungcweti kufanele isetshenziselwe ukuqinisekisa insimu kagesi ezinzile.
Lungisa i-electrostatic voltage ngokuya ngobulukhuni be-shipe yensimbi, ngokuvamile elawulwa phakathi kuka-50-80 kV.
Kuma-arvices abuyindisi anezimbobo eziyimpumputhe noma ama-cavities angaphakathi, uhlelo oluyisibhamu noma isibhamu esizwakalayo sokufakelwa singasetshenziswa ukugwema izindawo ezibuthakathaka ze-coating eviving emkhakheni kagesi.
ICEBISO 5: Ukwelashwa kwezithombe kuthuthukisa ukusebenza kwe-anti-torposion
Ukwelashwa kwe-phosphating akunakuthuthukisa ukumelana nokugqwayiza kwe-substrate, kepha futhi kuthuthukise ukunamathela kwezingubo ezilandelayo:
Ukulawulwa kokushisa: Ukushisa kwe-phosphating okunconyiwe kwensimbi kuphakathi kuka-50-70 ℃. Kuphezulu kakhulu noma okuphansi kakhulu kuzothinta ukufana kwefilimu ye-phosphating.
Ukuhlelwa kwesikhathi: Ngokuvamile imizuzu emi-3 ukuya kwe-10, kulungiswe ngokuya ngezidingo zezinhlelo zokusebenza.
Ukuphakamisa Ukusikisela: Sebenzisa ubuchwepheshe bezinga lokushisa eliphansi ukunciphisa ukusetshenziswa kwamandla, futhi uhlanganise nesisombululo semvelo esinobungane be-phosphating ukunciphisa umfutho wokwelashwa kwamanzi wezimboni.
Ithiphu 6: Kahle amaphuzu aphezulu wenqubo ye-electroplating
I-ElectroPlating inganikeza izakhiwo ezinhle kakhulu zokuhlobisa nezivikelayo, kepha idinga ukulawulwa okuphezulu kwenqubo:
Ukuqina kwamanje kanye nokushisa kufanele kufane nalo ngokuphelele. Isibonelo, lapho i-galvaning, izinga lokushisa kufanele libe phakathi kuka-20-30 ℃ nokuqina kwamanje kufanele kugcinwe ku-2-4 A / DM².
Ukuqoqwa kwezithasiselo kwikhambi le-electroplating kufanele kubhekwe njalo ukuze kuqinisekiswe ubushelelezi nobuningi bokuhlanganiswa.
QAPHELA: Ukuhlanza Ngemuva kokuthi i-electroplating ibalulekile. Isixazululo se-electroplating esandayo singadala ukugqwala noma ukugqwala ebusweni be-coating.
Ithiphu 7: Anodizing (okukhethekile kwezingxenye ze-aluminium)
I-Anodizing inqubo eyinhloko yokwenza ngcono ukumelana nokukhulisa kanye nomphumela wokuhlobisa wezingxenye zensimbi ye-aluminium eshidi:
I-voltage inconywa ukuthi ilawulwe ngo-10-20 v, futhi isikhathi sokucubungula siyalungiswa ngokuya ngezidingo (imizuzu engama-20-60).
Ukudaya nokubopha ngemuva kokuthi i-oxidation yizinyathelo ezibalulekile zokuthuthukisa umthamo we-antioxidant kanye nokuqina kombala.
Ubuchwepheshe obuthuthukisiwe: Sebenzisa ubuchwepheshe be-micro-arc oxidation (Mao) ukuze uthuthukise ubulukhuni futhi ugqoke ukumelana kwefilimu le-oxide.
Ithiphu 8: Ukugaya okungaphezulu kwe-polishing ukuthuthukisa ukunemba
Ukwelashwa okuphezulu kwekhwalithi ephezulu akuhlukaniswa kusuka ekugayeni nasekupholizweni:
Ukukhetha i-Sandpaper: Ukusuka ekuhlanganiseni kuya kokulungile, isinyathelo ngesinyathelo, ngokwesibonelo, kuqale ukusetshenziswa ngo-320 #, khona-ke uguquko kuya ku-800 # noma i-mesh ephakeme.
Ukusebenza okungaguquki: Isiqondiso sokugaya kufanele singaguquguquki ukuze sigweme ukuklwebheka okuthinta ukubukeka.
Kwemisebenzi yokusebenza ngezidingo eziphezulu eziluhlaza okwesibhakabhaka, isibuko se-polishing singasetshenziswa, kuhlangene ne-polishing paste noma i-chromium oxide paste ukuze uthuthukise umphumela.
ICEBISO 9: Qinisa ukuhlolwa kwekhwalithi nokulawulwa kwenqubo
Ukuqina kwekhwalithi yokwelashwa komhlaba kuhlukaniswe kusuka ekuhlolweni nasekulawuleni:
I-coating reagen gauge: Thola ubukhulu be-coation.
Ukuhlolwa kokunamathela: njengokuhlolwa kokusika noma ukudonsa kokugcina, ukuqinisekisa ukuthi ukuhlanganiswa kuqinile yini.
Ukuhlolwa kosawoti okusawoti: ukuhlola ukumelana nokukhulisa.
Iziphakamiso zokwenza ngcono: Ngokwethula imishini yokuhlola ezenzakalelayo, qinisekisa ukusebenza kahle kokuhlola, futhi kuhlanganise ukuhlaziywa kwedatha yenqubo yenqubo yangempela.
ICEBISO 10: Ukufunda okuqhubekayo nokufunda kwezobuchwepheshe
Ubuchwepheshe bokwelashwa okungaphezulu bushintsha ngoSuku ngalunye lokudlula, futhi ukugcina ubuholi bobuchwepheshe budinga:
Naka izitayela zezimboni: Bamba izitayela zakamuva zenqubo ngokuhlanganyela emibukisweni naseminars.
Ukutshalwa kwemali kweTekhnoloji R & D: Yethula imishini ehlakaniphile kanye nezinto ezintsha zemvelo zokwenza ngcono ukusebenza kahle kanye nokuvikela imvelo.
Isibonelo, ubuchwepheshe obuqhamukayo obunjenge-Nano Coatings kanye nokufafaza kwe-plasma kancane kancane kuyakhuthazwa, kuhlinzeka ngamathuba amaningi emkhakheni wokwelashwa komhlaba.
