*Izici Zomkhiqizo:
.Ukumelana okuhle kwamakhemikhali nokumelana namanzi
.Ukumelana nowoyela wamaminerali, amafutha emifino, izinyibilikisi ze-petroleum neminye imikhiqizo ye-petroleum
.Ifilimu kapende iqinile futhi iyacwebezela.Ukushisa kwefilimu, hhayi obuthakathaka, hhayi okunamathelayo

| Inkungu engazweli usawoti (800h) | akukho shintsho kufilimu kapende. |
*Ukusetshenziswa komkhiqizo:
Isetshenziswa ezinhlelweni zokonga amanzi, amathangi kawoyela ongahluziwe, ukugqwala kwamakhemikhali okujwayelekile, imikhumbi, izakhiwo zensimbi, zonke izinhlobo zezakhiwo zikakhonkolo ezimelana nokukhanya kwelanga.
*Upende Olufanayo:
Isetshenziswa ezinhlelweni zokonga amanzi, amathangi kawoyela ongahluziwe, ukugqwala kwamakhemikhali okujwayelekile, imikhumbi, izakhiwo zensimbi, zonke izinhlobo zezakhiwo zikakhonkolo ezimelana nokukhanya kwelanga.
*Ukwelashwa komhlaba:
Ingaphezulu le-primer kufanele lihlanzeke, lome futhi lingangcoli.Sicela unake isikhawu sokumboza phakathi kokwakhiwa kanye ne-primer.
*Umbandela Wokwakha:
Izinga lokushisa elingaphansi kwe-substrate alikho ngaphansi kuka-5 ℃, futhi okungenani li-3 ℃ liphakeme kunezinga lokushisa lendawo yamazolo, futhi umswakama ohlobene ngu-<85% (izinga lokushisa kanye nomswakama ohlobene kufanele ulinganiswe eduze nendawo engaphansi).Ukwakhiwa kwenqatshelwe ngokuphelele kunenkungu, imvula, iqhwa, nesimo sezulu esinomoya.
Gcoba ngaphambili i-primer nopende ophakathi, bese womisa umkhiqizo ngemva kwamahora angu-24.Inqubo yokufafaza isetshenziselwa ukufafaza izikhathi ezingu-1-2 ukuze kuzuzwe ubukhulu befilimu obucacisiwe, futhi ubukhulu obunconywayo bungama-60 μm.Ngemuva kokwakhiwa, ifilimu yepende kufanele ibe bushelelezi futhi ivuleke, futhi umbala kufanele uhambisane, futhi akufanele kube khona ukugoqa, ama-blistering, ikhasi le-orange nezinye izifo zepende.
*Amapharamitha wokwakha:
Isikhathi sokupheka: imizuzu engama-30 (23 ° C)
Ukuphila konke:
| Izinga lokushisa,℃ | 5 | 10 | 20 | 30 |
| Ukuphila konke (h) | 10 | 8 | 6 | 6 |
Isilinganiso esincane (isilinganiso sesisindo):
| Ukufafaza okungenamoya | Ukufafaza komoya | Ibhulashi noma i-roll coating |
| 0-5% | 5-15% | 0-5% |
Isikhathi sokubuyisela (ubukhulu befilimu ngayinye eyomile 35um):
| Izinga lokushisa le-ambient, ℃ | 10 | 20 | 30 |
| Isikhathi Esifushane Kakhulu, h | 24 | 16 | 10 |
| Isikhathi eside kakhulu, usuku | 7 | 3 | 3 |
*Indlela yokwakha:
Ukufafaza: ukufafaza okungewona umoya noma ukufutha ngomoya.Kunconywa ukusebenzisa i-high pressure non gas spraying.
I-brush / roll coating: kufanele ifinyelele ubukhulu befilimu eyomile eshiwo.
*Izinyathelo zokuphepha:
Sicela unake zonke izimpawu zokuphepha emaphaketheni ngesikhathi sokuthutha, ukugcinwa kanye nokusebenzisa.Thatha izinyathelo ezidingekayo zokuvikela nokuvikela, ukuvikela umlilo, ukuvikela ukuqhuma nokuvikela imvelo.Gwema ukuhogela umoya we-solvent, gwema ukuthintana nesikhumba namehlo ngopende.Ungawugwinyi lo mkhiqizo.Uma kwenzeka ingozi, funa usizo lwezokwelapha ngokushesha.Ukulahlwa kukadoti kufanele kuhambisane nemithetho kahulumeni kazwelonke nowendawo yokuphepha.
*Iphakheji:
Upende:20Kg/Ibhakede;
I-ejenti Yokwelapha/I-Hardener: 4Kg/Ibhakede
upende:i-ejenti yokwelapha/i-hardener=5:1 (isilinganiso sesisindo)
