Emkhakheni wokucubungula insimbi yeshidi, ukwelashwa okungaphezulu akuthinti nje kuphela ukubonakala komkhiqizo, kodwa futhi kuhlobene ngokuqondile nokuqina kwawo, ukusebenza kanye nokuncintisana kwemakethe. Noma ngabe isetshenziswa ezintweni ezisetshenziswa ezimbonini, ekwenziweni kwezimoto, noma ezintweni zikagesi, izinqubo zekhwalithi ephezulu zokwelashwa zingathuthukisa kakhulu ikhwalithi yomkhiqizo kanye nenani elengeziwe. Amathiphu angukhiye angu-10 alandelayo aklanyelwe ukukusiza ukuthi uthuthukise ukugeleza kwenqubo yokwelashwa kwendawo yensimbi yeshidi futhi usize ukuzuza imiphumela emihle kakhulu ngokuyimpumelelo.
Ithiphu 1: Ukwelashwa kwangaphambili okunembe
Ngaphambi kokuba noma iyiphi inqubo yokwelapha engaphezulu iqale, ukunakekelwa kahle kwendawo yonke kuyisisekelo sokuqinisekisa umphumela wokwelashwa okulandelayo.
Ukukhipha uwoyela ongaphezulu, ama-oxide nokugqwala kuwumsebenzi wokuqala. Ungasebenzisa ama-degreaser angochwepheshe noma okokususa ukugqwala, okuhlanganiswe nokucwiliswa emanzini, ukufutha noma ukusula ngesandla.
Ukungcola okunenkani, ukugaya ngomshini (okufana ne-sandpaper, isondo lokugaya, njll.) kungasetshenziswa.
Naka lapho usebenza:lawula amandla ukuze ugweme ukulimaza indawo engaphansi, ikakhulukazi izingxenye zensimbi zeshidi ezacile.
Iziphakamiso zokuthuthukisa: Sebenzisa okokusebenza okuzenzakalelayo kokwelapha (njengamasistimu okufuthwa) ukuze uqinisekise ukusebenza kahle nokuvumelana, ikakhulukazi ekukhiqizeni ngobuningi.
Ithiphu 2: Khetha into efanele yokuhlanganisa
Izimo zokusetshenziswa ezihlukene zinezidingo ezihlukene zezinto zokumboza zezingxenye zensimbi:
Imvelo yangaphandle: Kunconywa ukusebenzisa i-coating enokumelana nesimo sezulu esiphezulu, njenge-fluorocarbon coating noma i-acrylic coating.
Izingxenye zokungqubuzana okuphezulu: I-polyurethane coating noma i-ceramic coating ikhethwa ukwandisa ukumelana nokugqoka.
Ngesikhathi esifanayo, ukunakwa kufanele futhi kukhokhwe ekunamatheleni kokugqoka, okungathuthukiswa nge-primer. Ngezimo zokufunwa okukhethekile (ezifana nezindawo zokulwa ne-antibacterial noma insulating), ukunamathela okusebenzayo kungacatshangelwa.
Amathiphu:Ubungane bezemvelo kanye nokuqukethwe okuphansi kwe-VOC (i-volatile organic compound) yezinto zokumboza kuba umkhuba wemakethe, futhi kungakhethwa ukunamathela okuluhlaza okotshani kanye nemvelo.
Ithiphu 3: Lungiselela imingcele yenqubo yokufafaza
Imingcele yenqubo yokufafaza inquma ngokuqondile ikhwalithi nokubukeka kwe-coating:
Futha ibanga lesibhamu: Kufanele ligcinwe liphakathi kuka-15-25 cm ukugwema ukuwohloka noma izinhlayiya ezimahhadla.
Ingcindezi yokufafaza: Kunconywa ukuthi ibe phakathi kuka-0.3-0.6 MPa ukuze kuqinisekiswe i-atomization efanayo kapende.
Isivinini sokufafaza kanye ne-engeli: Ezindaweni zokusebenza ezinomumo oyinkimbinkimbi, lungisa i-engeli yesibhamu sokufutha ukuze uqinisekise ukumbozwa okufanayo koqweqwe emaphethelweni nasemifuleni.
Iziphakamiso zokuthuthukisa:Yenza izivivinyo zokumboza isampula ngesikhathi sesigaba sokuqinisekisa ukuze ulungiselele izilungiselelo zepharamitha futhi uqinisekise ukuzinza ekukhiqizeni okukhulu.
Ithiphu 4: Sebenzisa ubuchwepheshe bokufafaza nge-electrostatic
Ukufafaza nge-electrostatic sekube yinketho yokuqala yokwelashwa kwendawo yesimanje ngenxa yezinga eliphezulu lokunamathela kanye nokufana:
Umthelela wesisekelo uyisihluthulelo sekhwalithi yokufafaza, futhi imishini yokumisa phansi kufanele isetshenziselwe ukuqinisekisa insimu kagesi ezinzile.
Lungisa i-electrostatic voltage ngokuya ngobunkimbinkimbi beshidi lensimbi, ngokuvamile elawulwa phakathi kuka-50-80 KV.
Kuma-workpieces ayinkimbinkimbi anezimbobo eziyizimpumputhe noma izimbobo zangaphakathi, isistimu yezibhamu ezimbili noma isifutho esisizwa ngesandla singasetshenziswa ukuze kugwenywe izindawo ezibuthakathaka zokugqoka okubangelwa umphumela wokuvikela insimu kagesi.
Ithiphu 5: Ukwelashwa kwe-Phosphating kuthuthukisa ukusebenza kwe-anti-corrosion
Ukwelashwa kwe-Phosphating akukwazi nje ukuthuthukisa ukumelana nokugqwala kwe-substrate, kodwa futhi kuthuthukise ukunamathela kwezingubo ezilandelayo:
Ukulawula izinga lokushisa: Izinga lokushisa elinconywayo le-phosphating lensimbi liphakathi kuka-50-70 ℃. Ukuphakama kakhulu noma okuphansi kakhulu kuzothinta ukufana kwefilimu ye-phosphating.
Isikhathi sokusetha: Ngokujwayelekile imizuzu emi-3-10, ilungiswa ngokuya ngezidingo zempahla kanye nenqubo.
Isiphakamiso sokuthuthukisa: Sebenzisa ubuchwepheshe be-phosphating obusezingeni eliphansi ukuze unciphise ukusetshenziswa kwamandla, futhi uhlanganise nesisombululo se-phosphating esivumelana nemvelo ukuze unciphise ingcindezi yokuhlanza amanzi angcolile ezimbonini.
Ithiphu 6: Bamba kahle amaphuzu angumongo wenqubo ye-electroplating
I-Electroplating ingahlinzeka ngezakhiwo ezinhle kakhulu zokuhlobisa nezivikelayo, kepha idinga ukulawulwa okunembayo okuphezulu kwenqubo:
Ukuminyana kwamanje kanye nezinga lokushisa kufanele kufaniswe ngokuqinile. Isibonelo, uma ufaka uthayela, izinga lokushisa kufanele libe phakathi kuka-20-30℃ futhi ukuminyana kwamanje kufanele kugcinwe ku-2-4 A/dm².
Ukugxila kwezithasiselo kusixazululo se-electroplating kufanele kuqashwe njalo ukuze kuqinisekiswe ukushelela nokushuba kwento yokumboza.
Qaphela: Ukuhlanza ngemva kwe-electroplating kubalulekile. Isixazululo se-electroplating eyinsalela singabangela ukugqwala noma ukugqwala ebusweni bento enamathelayo.
Ithiphu 7: I-anodizing (okukhethekile izingxenye ze-aluminium)
I-Anodizing iyinqubo eyinhloko yokuthuthukisa ukumelana nokugqwala nomphumela wokuhlobisa wezingxenye zensimbi ze-aluminium:
I-voltage inconywa ukuthi ilawulwe ku-10-20 V, futhi isikhathi sokucubungula silungiswa ngokuvumelana nezidingo (imizuzu engu-20-60).
Ukudaya nokubeka uphawu ngemva kwe-oxidation yizinyathelo ezibalulekile zokuthuthukisa umthamo we-antioxidant nokuqina kombala.
Ubuchwepheshe obuthuthukisiwe: Sebenzisa ubuchwepheshe be-micro-arc oxidation (MAO) ukuze uqhubeke nokuthuthukisa ubulukhuni nokumelana nokugqoka kwefilimu ye-oxide.
Ithiphu 8: Ukugaya ubuso nokupholisha ukuze kuthuthukiswe ukunemba
Ukwelashwa kwendawo ephezulu akuhlukaniseki ekugayeni nasekupholishweni:
Ukukhetha iphepha lesandpaper: Ukusuka kokumaholoholo ukuya kokucolekile, isinyathelo ngesinyathelo, isibonelo, qala usebenzise u-320#, bese ushintshela ku-800# noma anezikhala eziphezulu.
Ukusebenza okungaguquki: Indlela yokugaya kufanele ihambisane ukuze kugwenywe ukuklwebheka okuphambanayo okuthinta ukubukeka.
Ngezinto zokusebenza ezinezidingo ezicwebezelayo eziphezulu, ukupholishwa kwesibuko kungasetshenziswa, kuhlanganiswe nokunamathisela kokupholisha noma ukunamathisela kwe-chromium oxide ukuze kuthuthukiswe umphumela.
Ithiphu 9: Qinisa ukuhlolwa kwekhwalithi nokulawula inqubo
Ukuzinza kwekhwalithi yokwelashwa okungaphezulu akuhlukaniseki ekuhlolweni nasekulawuleni:
I-coating gauge ukujiya: thola ukujiya kokunamathela.
Ukuhlolwa kokunamathela: okufana nokuhlolwa kokunqamula noma ukudonsa, ukuze kuqinisekiswe ukuthi ukunamathela kuqinile yini.
Ukuhlolwa kwesifutho sikasawoti: ukuhlola ukumelana nokugqwala.
Iziphakamiso zokuthuthukisa: ngokwethula okokusebenza kokuhlola okuzenzakalelayo, qinisekisa ukusebenza kahle kokuhlola, futhi uhlanganise ukuhlaziywa kwedatha ukuze kuthuthukiswe inqubo yesikhathi sangempela.
Ithiphu 10: Ukufunda okuqhubekayo kanye nokuqanjwa kabusha kwezobuchwepheshe
Ubuchwepheshe bokwelashwa kwendawo buyashintsha usuku nosuku, futhi ukugcina ubuholi bezobuchwepheshe kudinga:
Naka okuthambekele embonini: bamba izitayela zakamuva zenqubo ngokubamba iqhaza emibukisweni nasezifundweni.
Ukutshalwa kwezimali kwe-R&D yobuchwepheshe: yethula amathuluzi ahlakaniphile kanye nezinto ezintsha ezingavumelani nemvelo ukuze kuthuthukiswe ukusebenza kahle nezinga lokuvikela imvelo.
Isibonelo, ubuchwepheshe obusafufusa obufana ne-nano coatings kanye nokufafaza kwe-plasma buthuthukiswa kancane kancane, kunikeza amathuba amaningi emkhakheni wokwelashwa okungaphezulu.
