Mechanism Ntawm Yasizer

Cov mechanism ntawm cov yas limizer yog qhov uas yuav muab cov khoom yas rau yas rau hauv polymer molecular chains, uas tsis muaj zog ntawm txoj kev nyuab siab ntawm cov xaim hluav taws xob molecular chains. Yog li, cov kev sib txuas ntawm cov xaim hluav taws xob polymer molecular chains ntau zog thiab cov crystallinity ntawm polymer molecular chains yog txo, thiaj li hais tias cov yas ntawm polymer yog nce, uas yog, qhov tseem ceeb tshaj rau tiv thaiv kev lag luam yog qhov kev nyuaj siab ntawm polymer molecular chains thiab crystallization cov polymer molecular chains. Lawv vam khom lub tshuaj thiab lub cev ntawm lub polymer. Intermolecular quab yuam ntawm polymer ntawm www.wpcsino.com: Thaum cov yas caws pliav ntxiv rau polymers ntawm www.wpcsino.com, nws yog qhov tseem ceeb uas cov yas cij plhaub ua ke sib koom ua ke thiab cov hnab yas ywj pheej muab kev sib txuas lus rau polymer molecules. Tshwj tsis yog tag nrho cov kev sib txuam no (nruab nrab ntawm cov yas yas thiab cov yas yas, cov yas yas thiab cov polymers, thiab nruab nrab ntawm polymers thiab polymers) yog tib yam me me, tej zaum yuav tsis muaj cov yas los tiv thaiv thiab yas los tiv thaiv. Www.wpcsino.com 1.Van der Waals quab yuam yog ib qho tsis muaj zog attraction ntawm cov molecules nyob hauv lub xeev uas muaj teeb meem. Van der Waals quab yuam muaj xws li kev qoj ib ce, kev quab yuam kom khaus thiab kev muaj peev xwm. Van der Waals quab yuam tsuas muaj qee cov teebmeem. Www.wpcsino.com (1) Dispersion force tshwm sim ntawm tag nrho cov ncov qaumteb qabteb los yog cov tsis muaj hnub sawv cev. Nws yog ib qho kev tuaj yeem tshwm sim los ntawm kev sib txuam ntawm cov me nyuam yaus, uas ua rau cov uas nyob ib sab nyob hauv heteropo uas nyob ib sab. Txawm li cas los xij, tsuas yog nyob hauv cov tshuab tsis-ncov, xws li benzene, polyethylene los yog polystyrene, cov dispersion force yog lub ntsiab tivthaiv. Ww.wpcsino.com (2) Inductive force Thaum ib lub lwg me me nrog cov dipole taag lawm ua rau lub plhom dipole nyob hauv ib qho chaw sib txoos tsis sib luag, qhov attraction ntawm qhov ntxeem tau dipole thiab qhov dipole uas yog qhov tseem ceeb yog hu ua quab yuam. Cov kua tsw qab muaj ib lub zog muaj zog vim tias lub siab ntawm lub tshuab hluav taws xob, xws li cov quab yuam ntawm lub cev tsis sib haum thiab cov polystyrene lossis benzene thiab polyvinyl acetate.
