Ekukhiqizweni kwezimboni zesimanje, Kungakhathaliseki ukuthi imishini nemishini, izinto zokwakha, noma ngisho nezimoto,upende wezimbonizidlala indima ebalulekile ekuzivikeleni nasekuzihlobiseni. Lesi sihloko sizochaza ngemininingwane izinhlobo zopende bezimboni, izici zazo, izimo zokusetshenziswa kwazo, kanye nendlela yokukhetha upende ofanele, okuzokusiza ukuthi wenze izinqumo ezinolwazi.
1. Izinhlobo Zopende Bezimboni
Izembozo zopende zezimboni zingahlukaniswa ngezigaba ezilandelayo ngokuya ngokwakheka kwazo, inhloso kanye nokusebenza kwazo:
1.1 Izimbozo ezisekelwe ku-solvent
Izembozo ezisekelwe ku-solvent ziyizembozo ezisekelwe ku-solvent eziphilayo ezinokugeleza okuhle nokunamathela. Izembozo ezivamile ezisekelwe ku-solvent zifaka:
Upende we-alkyd: Ufanelekela izindawo zensimbi, ezinokumelana nesimo sezulu esihle kanye nokucwebezela.
Upende we-Epoxy: unokumelana okuhle kakhulu nokugqwala kanye nokunamathela, ofanele imishini yamakhemikhali kanye nemikhumbi kanye neminye imikhakha.
Upende we-polyurethane: Ukumelana nokuguguleka okunamandla, okulungele ukuvikela phansi kanye nemishini yemishini.
1.2 Upende osekelwe emanzini
Upende osekelwe emanzini usebenzisa amanzi njengesinyibilikisi, unobungani nemvelo, futhi unokuqukethwe okuphansi kwe-volitable organic compound (VOC). Upende ovamile osekelwe emanzini uhlanganisa:
Upende we-epoxy osekelwe emanzini: Kufanelekela izindawo zensimbi nezekhonkrithi ngaphakathi nangaphandle, ezinokumelana okuhle kwamakhemikhali.
Upende we-polyurethane osekelwe emanzini: ufanelekela izindawo zokhuni nezensimbi, omelana nokuguguleka okuhle kakhulu futhi ocwebezelayo.
1.3 Izembozo Ezikhethekile
Kukhiqizwa izembozo ezikhethekile zezidingo ezithile, ezivamile zifaka:
Isimbozo esivimbela umlilo: esisetshenziselwa ukuvikela umlilo ezakhiweni, singanciphisa ngempumelelo ukusabalala komlilo.
Ukugqoka okulwa namagciwane: Kufanelekile ezibhedlela, ekucubungulweni kokudla nakwezinye izindawo, kunomsebenzi wokuvimbela ukukhula kwamagciwane.
2. Ukukhethwa kwezingubo zokupenda zezimboni
Ukukhetha upende wezimboni ofanele kudinga ukucabangela izici eziningi, okuhlanganisa indawo yokusetshenziswa, uhlobo lwesisekelo, izidingo zokusebenza, njll.
2.1 Khetha ngokuya ngendawo yokusetshenziswa
Indawo yangaphakathi: Ukuze kusetshenziswe ngaphakathi, kunconywa ukuthi ukhethe upende osekelwe emanzini noma upende osekelwe ku-low VOC solvent ukuze kuncishiswe ukungcola komoya.
Indawo engaphandle: Upende osetshenziswa ngaphandle kudingeka ube nokumelana okuhle nesimo sezulu kanye nokumelana ne-UV. Kunconywa upende olunempuphu ye-polyester noma upende olusekelwe ku-solvent olumelana kakhulu nesimo sezulu.
2.2 Ukukhetha ngokusekelwe ohlotsheni lwesisekelo
I-Metal Substrate: Ezindaweni zensimbi, upende we-epoxy kanye nopende we-polyurethane kuyizinketho ezinhle, ezinamathela kahle futhi ezimelana nokugqwala.
Isisekelo sekhonkrithi: Upende we-epoxy osekelwe emanzini kanye nezingubo ezikhethekile ezingangeni manzi zilungele izindawo zekhonkrithi futhi zingavimbela ngempumelelo ukuvuza kwamanzi nokugqwala.
2.3 Ukukhetha okusekelwe ezidingweni zokusebenza
Ukumelana namakhemikhali: Uma isembozo sidinga ukumelana nokuhlaselwa ngamakhemikhali, upende we-epoxy yisinqumo esingcono kakhulu.
Ukumelana nokuguguleka: Ezitezi kanye nemishini yemishini, upende we-polyurethane kanye nopende wempuphu kunokumelana okuhle kokuguguleka.
3. Amasimu okusetshenziswa kopende bezimboni kanye nopende
3.1 Ukukhiqiza Imishini
Embonini yokukhiqiza imishini, izembozo zisetshenziswa kakhulu ukuvimbela ukugqwala nokuthuthukisa ukubukeka kwemishini. Upende we-Epoxy kanye ne-polyurethane uvame ukusetshenziswa, okwandisa ngempumelelo impilo yemishini.
3.2 Imboni Yokwakha
Isidingo semboni yezokwakha sokugqoka sigxile kakhulu ekuvimbeleni amanzi, ekuvikeleni umlilo, nasekuhlobiseni. Izingubo zokugqoka ezivimbela umlilo kanye nezingubo ezisekelwe emanzini zisetshenziswa kabanzi ekwakheni ukuze kuhlangatshezwane nezidingo zokusebenza ezahlukahlukene.
3.3 Ezokuthutha
Emkhakheni wezokuthutha, izembozo zisetshenziswa kakhulu ekuvikeleni ukugqwala kanye nobuhle bezimoto nemikhumbi. Izembozo ze-Epoxy kanye ne-polyurethane zisetshenziswa kabanzi ngenxa yokumelana kwazo okuhle kakhulu nesimo sezulu kanye nokumelana nokuguguleka.
3.4 Ukukhiqiza Ifenisha
Ekwenzeni ifenisha, upende olusekelwe emanzini kanye nopende we-polyurethane kuvame ukusetshenziselwa ukumboza izindawo zokhuni, okungeke nje kuvikele ukhuni kuphela kodwa futhi kuthuthukise ukubukeka kwalo.
4. Izinyathelo zokuphepha zokwakhiwa kopende wezimboni
Ngesikhathi senqubo yokupenda, ikhwalithi yokwakha ithinta ngqo ukusebenza kanye nokubukeka kwesembozo. Nazi ezinye zezinyathelo zokuphepha zokwakha:
4.1 Ukulungiswa Kwe-Substrate
Ngaphambi kokupenda, i-substrate idinga ukuhlanzwa nokwelashwa ukuqinisekisa ukuthi indawo ayinawo amafutha, uthuli kanye nokugqwala ukuze kuthuthukiswe ukunamathela kwengubo.
4.2 Izimo Zemvelo
Uma upenda, kufanele ukhethe izimo zemvelo ezifanele. Izinga lokushisa kanye nomswakama kunomthelela omkhulu ekomeni nasekuqineni kopende. Ngokuvamile, kunconywa ukufaka upende endaweni enezinga lokushisa elingu-15-30°C kanye nomswakama ongu-40%-70%.
4.3 Ukulingana Kopende
Uma upende udinga ukuhlanganiswa, hlanganisa ngokuqinile ngokwesilinganiso esinikezwe umenzi ukuqinisekisa ukusebenza kanye nomphumela wopende.
4.4 Amathuluzi Okwakha
Khetha ithuluzi lokufaka elifanele, njengesibhamu sokufafaza, i-roller noma ibhulashi, ukuqinisekisa ukuthi i-coat ilingana futhi ugweme ukugeleza namabhamuza.
5. Isifinyezo
Ngokuqonda nokukhetha izinhlobo ezahlukene zokumboza, ungathola umkhiqizo ofanele kakhulu izidingo zakho ezithile. Kungakhathaliseki ukuthi kusemishinini yokukhiqiza, ekwakheni, noma kwezokuthutha, ukukhetha ukumboza okulungile akugcini nje ngokuthuthukisa ukuqina komkhiqizo kodwa futhi kuthuthukisa ubuhle bawo.
