Ntlafatsa tlamahano ea mochini

Ka ho ntlafatsa ho phunyeletsa le ho nosetsa ha ho roala ho substrate, ho roala ho ka kenella ka har'a li-pores le mapetsong a substrate ka hohle kamoo ho ka khonehang. Ka mor'a ho tiisa, liankora tse nyenyane tse se nang palo li thehoa ho tiisa ka thata substrate, ka hona ho ntlafatsa ho khomarela filimi ea ho roala ho substrate.

Ntlafatsa matla a Van Der Waals

Ho ea ka lipalo, ha sebaka se pakeng tsa lifofane tse peli ke 1 nm, matla a van der Waals a ka fihla 9.81 ~ 98.1 MPa. Ka ho ntlafatsa mongobo oa ho roala ho substrate, ho roala ho ka kolobisoa ka hohle kamoo ho ka khonehang 'me ho haufi le sebaka sa substrate pele ho phekoloa, ka tsela eo ho eketsa matla a van der Waals' me qetellong ho ntlafatsa ho khomarela filimi ea ho roala ho substrate.

Fana ka lihlopha tse sebetsang hantle 'me u thehe maemo bakeng sa ho thehoa ha li-hydrogen bond le lik'hemik'hale tsa lik'hemik'hale

Matla a hydrogen bond le lik'hemik'hale tsa lik'hemik'hale li matla ho feta matla a van der Waals. Bahlahisi ba li-adhesion tse kang li-resin le li-coupling agents ba fana ka lihlopha tse sebetsang tse kang amino, hydroxyl, carboxyl kapa lihlopha tse ling tse sebetsang, tse ka etsang li-hydrogen bond kapa lik'hemik'hale tsa lik'hemik'hale tse nang le liathomo tsa oksijene kapa lihlopha tsa hydroxyl holim'a substrate, kahoo li ntlafatsa ho khomarela.

Phatlalatso

Ha substrate e koahetsoeng e le thepa ea polymer, solvent e matla kapa chlorinated polyolefin resin adhesion promoter e ka sebelisoa. E ka khothalletsa ho arohana le ho qhibiliha ha limolek'hule tsa ho roala le tsa substrate, qetellong ea etsa hore sebopeho se nyamele, kahoo se ntlafatsa ho khomarela pakeng tsa filimi ea ho roala le substrate.
