Ngaphambi kokuqonda abagqugquzeli bokunamathela, kufanele siqale siqonde ukuthi yini ukunamathela.

Ukunamathela: Isenzakalo sokunamathela phakathi kwendawo eqinile kanye nokuxhumana kwenye into ngokusebenzisa amandla amangqamuzana. Ifilimu yokumboza kanye ne-substrate ingahlanganiswa ndawonye ngokusebenzisa i-mechanical bonding, i-adsorption ebonakalayo, i-hydrogen bonding kanye ne-chemical bonding, ukusabalalisa okufanayo neminye imiphumela. Ukunamathela okukhiqizwa yile miphumela kunquma ukunamathela phakathi kwefilimu kapende kanye ne-substrate. Lokhu kunamathela kufanele kube isamba samandla ahlukahlukene okubopha (amandla okunamathela) phakathi kwefilimu kapende ne-substrate.
Kuyimpahla eyinhloko yezingubo zokugqoka ukudlala indima yokuvikela, ukuhlobisa kanye nemisebenzi ekhethekile. Ngisho noma i-coating ngokwayo inezakhiwo ezinhle kakhulu zomzimba namakhemikhali, ngeke ibe nenani eliwusizo kakhulu uma ingakwazi ukubopha ngokuqinile ne-substrate surface noma i-base coat. Lokhu kubonisa ukubaluleka kokunamathela ekusebenzeni kwe-coating.
Lapho ukunamathela kwefilimu kapende kungalungile, izinyathelo ezinjengokugaya i-substrate, ukunciphisa i-viscosity yokwakha enamathela, ukwandisa izinga lokushisa lokwakha, nokomisa kungathathwa ukuze kuthuthukiswe amandla okubopha ngomshini kanye nomphumela wokusabalalisa, ngaleyo ndlela kuthuthukiswe ukunamathela.

Ngokuvamile umgqugquzeli wokunamathela uyinto ethuthukisa isibopho phakathi kwezindawo ezimbili, okwenza isibopho sibe namandla futhi sihlale isikhathi eside.
Ukwengeza abagqugquzeli bokunamathela ohlelweni lokumboza nakho kungenye yezindlela eziphumelela kakhulu zokuthuthukisa ukunamathela.

Abagqugquzeli bokunamathela banezindlela ezine zokwenza:
I-Chemical anchoring yakho kokubili ifilimu kapende kanye ne-substrate;
I-Chemical anchoring yefilimu kapende nokugoqa ngokomzimba kwe-substrate;
Ukugoqa okungokomzimba kwefilimu kapende kanye ne-anchoring yamakhemikhali ye-substrate;
Ukugoqa okungokoqobo kokubili ifilimu kapende kanye ne-substrate.

Ukuhlukaniswa kwabagqugquzeli bokunamathela abavamile
1. Abagqugquzeli bokunamathela kwe-polymer Organic. Abagqugquzeli abanjalo bokunamathela ngokuvamile baqukethe amaqembu okunamathisela e-substrate njenge-hydroxyl, carboxyl, phosphate, noma izakhiwo ze-polymer ezinochungechunge olude, okuthuthukisa ukuguquguquka kwefilimu kapende futhi kuthuthukise ukunamathela kwefilimu kapende ku-substrate.
2. Abagqugquzeli bokunamathela ejenti yeSilane. Ngemuva kokuthi ukugqoka ngenani elincane le-agent yokuhlanganisa i-silane kusetshenziswe, i-silane ithuthela esibonakalayo phakathi kokugqoka kanye ne-substrate. Ngalesi sikhathi, lapho ihlangana nomswakama ebusweni be-substrate, ingafakwa nge-hydrolyzed ukuze yakhe amaqembu e-silanol, bese yenza izibopho ze-hydrogen namaqembu e-hydroxyl ebusweni be-substrate noma i-condense ibe yi-Si-OM (M imele indawo engaphansi) izibopho ezihlangene; ngesikhathi esifanayo, amaqembu e-silanol phakathi kwama-molecule e-silane ahlanganisana ukuze enze isakhiwo senethiwekhi esimboza ifilimu.

Izinto okufanele zicatshangelwe lapho ukhetha abagqugquzeli bokunamathela
Ukuhambisana kwesistimu;
Ukuqina kwesitoreji;
Ithonya ezintweni eziyisisekelo ezingokomzimba namakhemikhali zokumboza;
Ukwelashwa kwe-surface substrates;
Ukuhlanganisa nezinye izinto zokusetshenziswa ukuze kuthuthukiswe ukwakheka kokunamathela.
