*Izici Zomkhiqizo:
Ukumelana okuhle kwamakhemikhali nokumelana namanzi
. Ayimelani namafutha amaminerali, amafutha emifino, izinyibilikisi zephethiloli kanye neminye imikhiqizo yephethiloli
Ifilimu yokupenda iqinile futhi iyacwebezela
Ukushisa kwefilimu, akubuthakathaka, akunamatheli
*Imininingwane Yobuchwepheshe:

| Inkungu engamelani nosawoti (800h) | akukho shintsho efilimini yopende. |
*Ukusetshenziswa Komkhiqizo:
Isetshenziswa kumaphrojekthi okulondolozwa kwamanzi, amathangi kawoyela ongahluziwe, ukugqwala kwamakhemikhali okuvamile, imikhumbi, izakhiwo zensimbi, zonke izinhlobo zezakhiwo zekhonkrithi ezingamelana nokukhanya kwelanga.
*Upende Ohambisanayo:
Isetshenziswa kumaphrojekthi okulondolozwa kwamanzi, amathangi kawoyela ongahluziwe, ukugqwala kwamakhemikhali okuvamile, imikhumbi, izakhiwo zensimbi, zonke izinhlobo zezakhiwo zekhonkrithi ezingamelana nokukhanya kwelanga.
*Ukwelashwa Komphezulu:
Ubuso be-primer kufanele buhlanzeke, bome futhi bungabi nokungcola.
Sicela unake isikhathi sokugqoka phakathi kokwakhiwa kanye ne-primer.
*Isimo Sokwakha:
Izinga lokushisa le-substrate alikho ngaphansi kuka-5 ℃, futhi okungenani liphakeme ngo-3 ℃ kunezinga lokushisa le-air dew point, kanti umswakama ohlobene ungaphansi kuka-85% (izinga lokushisa kanye nomswakama ohlobene kufanele kulinganiswe eduze kwe-substrate). Ukwakhiwa akuvunyelwe ngokuphelele enkungwini, emvuleni, eqhweni, nasesimo sezulu esinomoya.
Gcoba kusengaphambili i-primer kanye nopende ophakathi, bese womisa umkhiqizo ngemva kwamahora angama-24. Inqubo yokufafaza isetshenziselwa ukufafaza izikhathi ezingu-1-2 ukuze kufezwe ubukhulu befilimu obubekiwe, kanti ubukhulu obunconywayo bungu-60 μm. Ngemva kokwakhiwa, ifilimu yopende kufanele ibe bushelelezi futhi ibe yisicaba, futhi umbala kufanele uhambisane, futhi akufanele kube nokugoba, ukuqhakaza, ikhasi le-orange kanye nezinye izifo zopende.
*Amapharamitha Okwakha:
Isikhathi sokupholisa: imizuzu engama-30 (23 ° C)
Isikhathi sokuphila:
| Izinga lokushisa, ℃ | 5 | 10 | 20 | 30 |
| Isikhathi sokuphila (h) | 10 | 8 | 6 | 6 |
Isilinganiso Esincane (isilinganiso sesisindo):
| Ukufutha Okungenamoya | Ukufutha Komoya | Isembozo sebhulashi noma sokugoqa |
| 0-5% | 5-15% | 0-5% |
Isikhathi sokuphinda simboze (ukujiya kwefilimu ngayinye eyomile 35um):
| Izinga lokushisa elizungezile, ℃ | 10 | 20 | 30 |
| Isikhathi Esifushane Kakhulu, h | 24 | 16 | 10 |
| Isikhathi eside kakhulu, usuku | 7 | 3 | 3 |
*Indlela Yokwakha:
Ukufutha: ukufutha ngaphandle komoya noma ukufutha ngomoya. Kunconywa ukusebenzisa ukufutha ngaphandle komoya ngomfutho ophezulu.
Isembozo sebhulashi/sokugoqa: kumele sifinyelele ubukhulu obubekiwe befilimu eyomile.
*Izinyathelo zokuphepha:
Sicela uqaphele zonke izimpawu zokuphepha ezikuphakheji ngesikhathi sokuthuthwa, ukugcinwa kanye nokusetshenziswa.
Thatha izinyathelo ezidingekayo zokuvimbela nokuvikela, ukuvimbela umlilo, ukuvikela ukuqhuma kanye nokuvikela imvelo.
Gwema ukuhogela umusi oncibilikisayo, gwema ukuthintana nesikhumba namehlo ngopende.
Ungagwinyi lo mkhiqizo.
Uma kwenzeka ingozi, funa usizo lwezokwelapha ngokushesha.
Ukulahlwa kwemfucuza kufanele kuhambisane nemithethonqubo yokuphepha kazwelonke neyendawo kahulumeni.
*Iphakheji:
Upende: 20Kg/Ibhakede;
I-ejenti yokwelapha/i-Hardener: 4Kg/Ibhakede
upende: i-ejenti yokwelapha/i-hardener = 5:1 (isilinganiso sesisindo)
