Dab tsi yog cov Cheebtsam ntawm Adhesive Strength ntawm Ib Zaj Yeeb Yam Tiv Thaiv?

Cov nplaum nplaum, tack, thiab cohesive quab yuam ntawm cov yeeb yaj kiab tiv thaiv qhov txawv ntawm cov nplaum nplaum ntawm cov yeeb yaj kiab tiv thaiv thiab cov nplaum, lub zog tev tom qab siv, thiab cov nplaum nplaum ntawm nws tus kheej. Kev nkag siab lub ntsiab lus ntawm cov rog no tso cai rau kev nkag siab zoo ntawm kev ua haujlwm ntawm cov yeeb yaj kiab tiv thaiv, ua kom muaj kev siv tag nrho ntawm cov khoom siv tiv thaiv zaj duab xis sib txawv.

Adhesion: Qhov no yog hais txog lub zog sib txuas ntawm cov nplaum thiab zaj duab xis. Yog hais tias lub tack quab yuam ntau dua lub adhesion quab yuam, cov bonds ntawm cov nplaum molecules thiab zaj duab xis yuav tawg thaum cov zaj duab xis tiv thaiv yog tev tawm, ua rau delamination.

Tack: Qhov no yog hais txog lub zog yuav tsum tau tev cov yeeb yaj kiab tiv thaiv los ntawm qhov chaw tom qab lub sijhawm. Tack muaj feem xyuam rau cov khoom siv, siab, lub sij hawm thov, tev lub kaum sab xis, thiab kub. Feem ntau, tack nce nrog lub sijhawm thiab siab. Lub tack ntawm cov yeeb yaj kiab tiv thaiv yuav tsum tsis txhob nce ntau dhau kom tsis muaj qhov seem seem tom qab tev. Kev kuaj 180-degree feem ntau yog siv los ntsuas tack.

Cohesion: hais txog lub zog sab hauv ntawm lub colloid. Kev sib koom ua ke ntawm cov colloid siv los ua cov yeeb yaj kiab tiv thaiv yuav tsum siab heev; txwv tsis pub, thaum cov yeeb yaj kiab tiv thaiv tau tawg, cov kab nrib pleb sab hauv ntawm cov colloid yuav ua rau cov khoom seem. Txoj kev ntsuas kev sib koom ua ke yog txhawm rau txuas cov yeeb yaj kiab tiv thaiv mus rau qhov chaw stainless hlau, tshem tawm qee qhov hnyav ntawm cov yeeb yaj kiab tiv thaiv, thiab ntsuas ntev npaum li cas rau cov yeeb yaj kiab tiv thaiv kom rub tawm los ntawm qhov hnyav. Yog tias qhov adhesion ntau dua li kev sib koom ua ke, cov kev sib txuas ntawm cov colloid molecules yuav tawg thaum cov yeeb yaj kiab tiv thaiv tau tawg, ua rau cov khoom seem.
