Sinthani mgwirizano wamakina

Mwa kupititsa patsogolo kulowetsedwa ndi kunyowa kwa chophimbacho kupita ku substrate, chophimbacho chimatha kulowa m'mabowo ndi ming'alu ya substrate momwe zingathere. Pambuyo polimba, ma nangula ang'onoang'ono ambiri amapangidwa kuti agwire mwamphamvu substrate, motero amawongolera kumamatira kwa filimu yophimba ku substrate.

Konzani mphamvu ya Van Der Waals

Malinga ndi kuwerengera, pamene mtunda pakati pa ndege ziwirizi ndi 1 nm, mphamvu ya van der Waals imatha kufika pa 9.81 ~ 98.1 MPa. Mwa kukweza kunyowa kwa chophimbacho ku substrate, chophimbacho chikhoza kunyowetsedwa mokwanira momwe zingathere komanso pafupi ndi pamwamba pa substrate chisanatsukidwe, motero kuwonjezera mphamvu ya van der Waals ndikupangitsa kuti filimu yophimbayo ikhale yolimba kwambiri.

Perekani magulu oyankha ndipo pangani mikhalidwe yopangira ma bond a haidrojeni ndi ma bond a mankhwala

Mphamvu ya ma hydrogen bonds ndi ma chemical bonds ndi yamphamvu kwambiri kuposa ya van der Waals forces. Zolimbikitsira ma adhesion monga ma resin ndi ma coupling agents zimapereka magulu osinthika monga amino, hydroxyl, carboxyl kapena magulu ena ogwira ntchito, omwe amatha kupanga ma hydrogen bonds kapena ma chemical bonds ndi ma atomu a okosijeni kapena magulu a hydroxyl pamwamba pa substrate, motero zimathandizira kuti ma adhesion ayambe kugwira ntchito bwino.

Kufalikira

Pamene gawo lophimbidwa ndi polymer, chotsukira champhamvu kapena cholimbikitsira kumatira kwa polyolefin resin chingagwiritsidwe ntchito. Chingathandize kufalikira ndi kusungunuka kwa mamolekyulu ophikira ndi gawo lophimbidwa, zomwe pamapeto pake zimapangitsa kuti mawonekedwe azitha, motero kumathandizira kuti filimu yophimbidwa ndi gawo lophimbidwa ikhale yogwirizana.
