Qhov tseem ceeb ntawm adhesives hauv cov khoom sib txhuam
Cov khoom sib txhuam ntawm kev sib txhuam phaj tuaj yeem muab faib ua peb yam: nplaum, ntxiv qhov ntxiv thiab muab tub lim. Ntawm peb cov khoom no, cov khoom tseem ceeb ntawm cov nplaum yog cob thiab hluavtaws roj hmab. Raws li cov khoom tseem ceeb ntawm cov khoom sib txhuam, kev cuam tshuam ntawm qhov zoo ntawm daim ntawv nplaum kev sib txhuam yog nws tus kheej, yog li thaum tsim cov ntawv sib txhuam, nws yuav tsum muaj qee qhov kev xav tau rau cov nplaum thaum xaiv cov khoom. Muaj peb yam uas yuav tsum tau muaj:
1. Txhawm rau xaiv cov resin nrog cov cua sov zoo li cov khoom siv nplaum, ntxiv rau, cov resin kuj yuav tsum muaj qhov kub siab thermal decomposition kub thiab thermal poob qis.
2. Txhawm rau xaiv cov hmoov nplej zoo heev, cov ntsiab lus tshaj lij yog tias cov hmoov nplej uas tau xaiv yuav tsum muaj qhov zoo heev, yog li ntawd nws yuav zoo li qub thaum cov khoom tawg thiab sib xyaw nrog lwm cov ntaub ntawv.
3. Cov resin xaiv yuav tsum muaj kev kho kom haum, khiav deb thiab cov ntsiab lus tsis muaj phenol.
Nws tuaj yeem pom tau tias kev xaiv cov nplaum nplaum yog qhov tseem ceeb ntawm cov khoom siv sib txhuam yog ib leeg, thiab nws yog txhua yam ua los ntawm kev xaiv ntawm cov resin, uas yog, los ntawm cov ntaub ntawv resin uas twb muaj lawm, qhov zoo tshaj plaws haum rau cov yam ntxwv. ntawm kev sib txhuam phaj thiab yog qhov zoo tshaj plaws rau nws txoj haujlwm yog xaiv. Ua si qhov zoo tshaj plaws los ua kom nws lub neej ua haujlwm ntev.
