Phucula ukudibanisa koomatshini

Ngokuphucula ukunyanzeliswa kunye nokumanzisa kwengubo kwi-substrate, i-coating inokungena kwii-pores kunye nokuqhekeka kwe-substrate kangangoko kunokwenzeka. Emva kokuqiniswa, iihange ezincinci ezingenakubalwa zenziwe ukuba zibambe ngokuqinileyo i-substrate, ngaloo ndlela iphucula ukunamathela kwefilimu yokugqoka kwi-substrate.

Ukuphucula amandla kaVan Der Waals

Ngokutsho kwezibalo, xa umgama phakathi kweendiza ezimbini ngu-1 nm, amandla e-van der Waals anokufikelela kwi-9.81 ~ 98.1 MPa. Ngokuphucula ukumanzisa kwengubo kwi-substrate, i-coating inokumanziswa ngokupheleleyo ngokusemandleni kwaye isondele kwi-substrate surface ngaphambi kokunyanga, ngaloo ndlela ikhulise amandla e-van der Waals kwaye ekugqibeleni iphucule ukunamathela kwefilimu yokugqoka kwi-substrate.

Ukubonelela ngamaqela asebenzayo kunye nokudala iimeko zokuqulunqwa kweebhondi ze-hydrogen kunye neebhondi zeekhemikhali

Ukomelela kweebhondi ze-hydrogen kunye neekhemikhali zebhondi zomelele ngakumbi kunoko kwamandla e-van der Waals. Abagqugquzeli be-adhesion ezifana ne-resins kunye ne-coupling agents banikezela ngamaqela asebenzayo afana ne-amino, i-hydroxyl, i-carboxyl okanye amanye amaqela asebenzayo, anokwenza iibhondi ze-hydrogen okanye iibhondi zeekhemikhali kunye ne-athomu ye-oksijini okanye amaqela e-hydroxyl ebusweni be-substrate, ngaloo ndlela iphucula ukubambelela.

Ukusasazwa

Xa i-substrate edibeneyo iyinto yepolymer, i-solvent eyomeleleyo okanye i-chlorinated polyolefin i-resin adhesion promoter ingasetyenziswa. Inokukhuthaza ukusasazwa okufanayo kunye nokuchithwa kwe-coating kunye ne-substrate molekyuli, ekugqibeleni kubangela ukuba i-interface ilahleke, ngaloo ndlela iphucula ukunamathela phakathi kwefilimu yokugqoka kunye ne-substrate.
