Qhov zoo tshaj yuav yog dab tsi ua rau Exude rau lub Plasticizer

Plasticizer tau ntxiv rau lub polymer kom muaj khoom tawg yooj yim, muab khoom softness ntawm tej qhov chaw tshuaj yam khoom, deb li deb tau ntau lawm thiab noj yog cov chiv ib yam. Niaj hnub muab khoom no tag nrho ntxiv lub plasticizer, xws li lub rooj zaum tawv, quilts nqus hnab, kawm nag, khau khiab ua luaj rau.

Tab sis thaum lub sij hawm mus rau plasticizer nyob rau yas kev xa, kev seepage thiab kev xaus lub neej sai migrated rau khoom, ze rau ntawm qhov nruab nrab deg los sis tso rau hauv qhov chaw, yuav muab cov khoom uas kawm poob, neeg tsis mloog hais ntawm qhov kev tes, seepage thiab xaus ntawm plasticizer rau cov ntaub ntawv kawm, nruab nrab thiab raws li tej paug los ntawm kev tiv tauj. Vim ntau hom plasticizer muaj qhov sib txawv compatibility yas, yog cov compatibility phem, tus plasticizer yog qho yooj yim uas yuav muab cais. Yuav cais tawm cov plasticizer uas tau, feem ntau paub tias "tawg"; Nag lossis daus cov kua plasticizer, hu ua "exudation". Qhov tseeb, lub Hoobkas yuav ntxiv cov ntaub ntawv sib txawv plasticizer ua ntej cov khoom yas hardness.

Yog li ntawd, nws tseem yuav analyzed rau yam uas txawv, txawv ntau ntawm seepage plasticizer. Rau cov kev mob ib yam, tus seepage yuav muab ntau zog thaum cov ntawv luam ntawm plasticizer muab ntau rau hauv qhov system Polyvinyl chloride (PVC). Nyob muaj siv, feem ntau ntawm cov plasticizer more than 33% cov ntaub ntawv kom muaj nuj nqis, muag khoom uas yuav cuag 43% ntawm plasticizer. Nws separates tau yooj yim nrog siab kev faib ua feem plasticizer nyob rau hauv cov khoom. Vim hais tias cov plasticzier ntau koj ntxiv, tab sis tus saturation no tas ces nws yuav high meem nag lossis daus. Ntxiv thiab, cov nag lossis daus ntawm plasticizer puas rhiab rau qhov kub thiab txias. Nws yuav cais paub ntxiv nrog rau qhov kub thiab txias siab ntxiv. Tab sis, muaj yog txawv obviously muaj plasticizer ntau rau qhov kub thiab txias.
