Emikhakheni eminingi efana nezinto zokwakha nezasendlini, amakhoyili ensimbi e-PPGI asetshenziswa kakhulu ngenxa yemibala yawo ecebile nokusebenza okuhle kakhulu. Kodwa bewazi yini ukuthi "eyandulelayo" yiKhoyili Yensimbi Eyinsimbi? Okulandelayo kuzoveza inqubo yokuthi Ikhoyili Yeshidi Elivunyiwe yenziwa kanjani Ikhoyili ye-PPGI.
1. Ukuqonda Amakhoyili Akhandiwe kanye namakhoyili e-PPGI
Amakhoyili Ayisithako Abakhiqizi bagcoba amakhoyili ngongqimba lwezinki ngaphezulu, okusebenza ngokuyinhloko ukugqwala - umsebenzi wokufakaza nokwandisa isikhathi sokusebenza kwensimbi. Amakhoyili ensimbi e-PPGI athatha amakhoyili ensimbi njenge-substrate. Ngemuva kochungechunge lokucubungula, i-organic coatings isetshenziswa ebusweni bayo. Ayigcini nje ngokugcina ukugqwala - izakhiwo zobufakazi bamakhoyili ensimbi kodwa futhi yengeza izici ezinhle kakhulu ezifana nobuhle kanye nokumelana nesimo sezulu.
2. Izinyathelo Ezibalulekile Zokukhiqiza Zefekthri Yensimbi Enguthayela
(1) Inqubo Yokwelapha Ngaphambili - Ukwehlisa amafutha: Ingaphezulu lamakhoyili ensimbi angase abe nokungcola okufana nowoyela nothuli. Lezi zinto ezingcolisayo zisuswa izixazululo ze-alkaline noma ama-chemical degreasing agents ukuze kuqinisekiswe inhlanganisela engcono yokumbozwa okulandelayo ne-substrate. Isibonelo, ukusetshenziswa kwesisombululo sokwehlisa amafutha esine-surfactant kungabolisa ngempumelelo ama-molecule kawoyela.
Ukwelashwa Kokuguqula Amakhemikhali: Okujwayelekile kufaka phakathi i-chromization noma i-chromium - ukwelashwa kwamahhala kwe-passivation. Yakha ifilimu yamakhemikhali emincane kakhulu ebusweni bongqimba olunothayela, ehlose ukuthuthukisa ukunamathela phakathi kwe-substrate nopende kuyilapho ithuthukisa ngokwengeziwe ukumelana nokugqwala. Le filimu ifana "nebhuloho", elivumela upende ukuthi uxhumeke eduze ikhoyili yensimbi.
(2) Inqubo Yokupenda - I-Primer Coating: I-primer isetshenziswa kukhoyili eyase ifakwe uthayela ngokusebenzisa i-roller coating noma ezinye izindlela. Umsebenzi oyinhloko we-primer ukuvimbela ukugqwala. Iqukethe ama-anti-rust pigments nama-resin, angakwazi ukuhlukanisa ngokuphumelelayo ukuxhumana phakathi komswakama, umoya-mpilo, kanye nongqimba lwama-galvanized. Isibonelo, i-epoxy primer inokunamathela okuhle nokumelana nokugqwala.
I-Topcoat Coating: Khetha ijazi lejazi elinemibala ehlukahlukene kanye nokusebenza ukuze kuhlanganiswe ngokwezidingo. Ijazi eliphezulu aligcini nje ngokunikeza ikhoyili ye-PPGI imibala ecebile kodwa futhi inikeza ukuvikeleka okufana nokumelana nesimo sezulu kanye nokumelana nokuguga. Isibonelo, i-polyester topcoat inemibala egqamile kanye nokumelana okuhle kwe-UV, okuyenza ifanele ukwakhiwa kwangaphandle. Amanye amakhoyili anemibala anopende ongemuva ukuze avikele ingemuva le-substrate ekugugulekeni kwemvelo.
(3) Ukubhaka Nokwelapha Umucu wensimbi opendiwe ungena esithandweni sokubhaka bese ubhakwa ezingeni lokushisa elithile (imvamisa engu-180℃ - 250℃). Ukushisa okuphezulu kwenza i-resin kupende ibhekane nesiphambano - ukuxhumanisa ukusabela, iqina ibe ifilimu futhi yenze i-coating eqinile. Isikhathi sokubhaka kanye nezinga lokushisa kufanele kulawulwe ngokunembile. Uma izinga lokushisa liphansi kakhulu noma isikhathi singanele, ifilimu yepende ngeke ilapheke ngokuphelele, ithinte ukusebenza; uma izinga lokushisa liphezulu kakhulu noma isikhathi siside kakhulu, ifilimu kapende ingase ibe phuzi futhi ukusebenza kwayo kungase kunciphe.
(4) I-post - processing (Ongakukhetha) Amanye amakhoyili ensimbi ye-PPGI athunyelwa - acutshungulwa njengokufaka imbossing, i-laminating, njll. ngemva kokuphuma kuhhavini. I-embossing ingakhuphula ubuhle nokungqubuzana kwendawo, futhi i-laminating ingavikela indawo yokumboza ngesikhathi sokuthutha nokucubungula ukuvimbela imihuzuko.
3. Izinzuzo kanye nokusetshenziswa kwamakhoyili ensimbi e-PPGI Ngokusebenzisa lolu hlelo olungenhla, ikhoyili yensimbi “iguqulwa” ngempumelelo ibe ikhoyili ye-PPGI. Ikhoyili ye-PPGI yinhle futhi iyasebenza. Emkhakheni wokwakha, zingasetshenziselwa izindonga zangaphandle nophahla lwamafektri. Ngemibala ehlukahlukene, zihlala isikhathi eside futhi azibuni. Emkhakheni wemishini yasendlini, njengeziqandisi namagobolondo e-air-conditioner, zombili zibukeka kahle futhi zigqoka - zimelana. Ukusebenza kwayo okuhle kakhulu kuyenza ibe nesikhundla esibalulekile ezimbonini eziningi. Ukusuka kukhoyili eyakhiwe ngamagalani kuya kukhoyili ye-PPGI, uguquko olubonakala lulula empeleni lubandakanya ubuchwepheshe obunembile kanye nefomula yesayensi. Isixhumanisi ngasinye sokukhiqiza sibalulekile, futhi ngokuhlangene bakha ukusebenza okuhle kakhulu kwekhoyili ye-PPGI, bengeza umbala kanye nokwenza lula embonini nempilo yesimanje.
