Yog tias koj xav paub seb nws puas zoo dua los xaiv qhov kev tsim kho lossis kub qhuav thaum koj yuav tsum nkag siab qhov sib txawv ntawm ob txoj kev sib txuas. Kub qhuav nplaum yog ib hom ntawm thermoplastic nplaum uas muaj cov teebmeem sib txawv raws li txoj kev sib txawv. Dab tsi yog qhov txawv ntawm khaub thuas thiab kub adhesion ntawm kub yaj cov nplaum? Cia peb tham txog qhov sib txawv ntawm ob!
1. Cold Adhesion
Cov nplaum nplaum txias feem ntau yog siv nyob rau hauv daim ntawv thov ntawm ntau lub siab-rhiab kub qhuav cov nplaum. Ntawm lawv, cov neeg sib tw ntau dua yog cov chaw sib khi ntawm cov khoom xa tuaj thiab hnab ntawv muaj txiaj ntsig, uas tau sib raug zoo-rhiab nplaum nplaum. Thov ib txheej ntawm kub yaj cov nplaum nrog thaum pib tack mus rau qhov khoom thiab tom qab ntawd npog nws nrog kev tso zaj duab xis lossis tso cov ntaub li. Thaum siv, daim ntawv tso tawm tuaj yeem raug tshem tawm thiab sib raug zoo, uas ua rau daws tau qhov kev sib raug zoo kom sai. Ntxiv mus, yuav tsis muaj kua nplaum ntxig rau hauv kev ua haujlwm txias, thiab yuav tsis muaj kev puas tsuaj ntau dhau rau saum npoo ntawm substrate. Ntev li cov txheej txheem nplaum yog sib chwv nrog lub substrate thiab maj mam nias cov nplaum, cov txiaj ntsig zoo nplaum tuaj yeem ua tiav.
2. Kub Sticking
Thermal tuam txhab, uas muaj ntau nyob rau hauv cov ntawv thov xws li lub kaus mom lub raj mis, kho tsheb ua lag luam, thiab siv Wicking. Zoo sib xws substrates muaj qee qhov kev xav tau rau cov nplaum kub thiab cov nplaum kom zoo dua, thiab cov nplaum nplaum kom zoo dua los txhawb kev sib xyaw ua ke ntawm colloids thiab substrates. Tshwj xeeb rau cov substrates nrog textured thiab zoo nqaws ntawm sab, uas muaj plua plav ntawm cov nplaum ntawm cov txheej txheem nplaum kom zoo nkauj rau txheej, thiab cov nplaum txheej tom qab ntev. Yog li no, kev siv cov nplaum nplaum kub tau muab cov nplais kub uas sau tau zoo nyob rau saum npoo ntawm substrate, yog li cov kua nplaum thiab yog li txhim kho cov nyhuv zoo tshaj plaws.
3. Qhov sib txawv ntawm cov nplaum nplaum txias thiab cov nplaum kub
Qhov loj tshaj qhov sib txawv ntawm cov nplaum thiab txias dua yog qhov sib txawv hauv kev ua si ntawm cov kua nplaum molecules. Nyob rau hauv lub xeev txias-adhesive, tus kub-melt lub siab-rhiab tau nplaum yog siv, thiab cov kua nplaum tau txias, thiab cov qauv molecular tau dhau los ua qhov ruaj khov, uas yooj yim dua rau kev siv; Txawm li cas los xij, thaum siv cov qauv nplaum kub yaj hauv lub xeev kev ua kom zoo nkauj ntawm cov qauv molecular ntawm cov qauv molecular ntawm cov nyiaj molecular ntawm cov khoom siv molecular ntawm cov khoom siv molecular ntawm cov khoom siv molecular ntawm cov nplaum kub yog qhov ntau dua kev puas tsuaj rau saum npoo ntawm substrate.
Tsawg tsawg lub substtrates tuaj yeem sib khi ob qho tib si txias thiab kub, thiab thaum koj nkag siab qhov rhiab heev ntawm cov txheej txheem kom kub, koj yuav paub txoj kev sib koom tes twg los xaiv.
