Nqus electroplating hluav taws xob cua sov raj daws qhov teeb meem ntawm cov xim tev

Cov yas adhesion txhawb nqa tsim ib txheej ntawm adhesion ntawm cov yas thiab cov xim txheej los txhawb kev sib xyaw ntawm cov substrate thiab txheej los ntawm cov ntsiab lus ntawm kev siv tshuab occlusion, intermolecular quab yuam, pab pawg ua haujlwm, thiab lwm yam, thiab txau ntau qhov chaw ntawm tib lub koob. ntawm cov ntaub ntawv yas. Cov xim muaj cov nyhuv adhesion zoo. Nyob rau hauv cov txheej txheem tshuaj tsuag yas, adhesion promoters feem ntau yog siv los tshuaj tsuag ntawm cov substrate thiab cov xim los txhim kho cov adhesion ntawm cov khaubncaws sab nraud povtseg thiab daws qhov teeb meem ntawm cov xim tev. Tom qab kuaj adhesion, cov xim tsis poob.

Nyob rau hauv txheej txheej txheej, kev ua tau zoo ntawm txheej txheej ntawm lub substrate muaj kev cuam tshuam zoo rau cov txheej txheem kho saum npoo ntawm cov yas. Cov adhesion tsis zoo yuav ua rau kev ua haujlwm thiab cov khoom zoo nkauj ntawm cov xim tsis zoo, thiab cov tshuaj tsuag yuav poob nws lub ntsiab lus. Yog li ntawd, txheej txheej txheej thiab lwm yam yuav tsum tau tswj xyuas cov txheej txheem kev ua haujlwm. Tom qab cov ntsiab lus tsim tawm tiag tiag, nws pom tias qhov teeb meem ntawm cov yas nws tus kheej thiab kev ntseeg siab ntawm kev sib xyaw nrog cov xim yog cov ntsiab lus tseem ceeb los daws qhov teeb meem ntawm cov xim tev.

Yuav ua li cas cov tshuaj tsuag yas txhim kho qhov adhesion ntawm cov xim pleev xim kom daws tau cov teeb meem ntawm cov xim pleev xim yas thiab lwm yam tsis zoo? Peb yam ntawm crystallinity, polarity thiab lub zog saum npoo ntawm cov ntaub ntawv yas muaj kev cuam tshuam zoo rau kev adhesion. Piv txwv li, cov khoom siv PP yog cov khoom siv tsis-polar nrog lub zog qis, thiab cov khoom siv nylon muaj crystallinity siab thiab lub zog me me. Yog li ntawd, yuav ua li cas ua kom lub ntsej muag ntawm cov khoom nquag thiab muaj kev sib raug zoo nrog cov xim yog qhov tseem ceeb los daws.
