Yuav ua li cas to taub cov polymer molecules ua ntej tsim cov tshuaj pwm?
Yas txhaj tshuaj pwm yog cov khoom siv plawg feem ntau siv, uas tsim tau cov yas thiab cov khoom ua kom zoo dua qub. Ua ntej tsim cov yas pwm, peb yuav tsum muaj kev paub txog cov yas. Lub ntsiab tivthaiv ntawm cov yas yog polymer.Such li ABS yas yog peb hom acrylonitrile, butadiene, styrene monomer los ntawm emulsion los yog rho tawm polymerization, ontology, muaj cov kev kawm zoo ntawm peb hom monomers thiab tuaj yeem molded, nyob rau hauv tej yam kub thiab siab txhaj rau cov kab noj hniav, thiab ua kom muaj kab noj hniav, tuav cov khoom yas, tom qab txias txias.Polymer molecular saw qauv hauv feem ntau, txoj kab hlau thiab cov ceg ntoo molecules xam cov thermoplastics, 39 thiab rov ua dua, txias / cua sov thiab tom qab cua sov , ntau hom kev sib cav sib cav sib ceg, txuas mus rau hauv cov qauv ntawm cov yas mesh loj feem ntau yog ib zaug, tsis rov ua cov zauv, thermosetting yas uas tau hais.Vim yog cov qauv saw, li ntawd cov kev coj ntawm cov yas shrinkage thaum ua thiab polymer molecule chains nyob rau hauv cov nyhuv ntawm cov kev taw qhia kev nyuab siab thiab txias contraction muaj feem xyuam rau txoj kev khiav ncaj nyob rau ntawm qhov ntswg contraction.Product shrinkage kuj yog hais txog khoom zoo, rooj vag, thermal expansion thiab txias shrinkage, kub, lub siab ceev lub sij hawm thiab kev ntxhov siab nrog.Feem ntau, tus shrinkage tus nqi muab nyob rau hauv phau ntawv yog heev thoob plaws. Nyob rau hauv daim ntawv thov, khoom lub phab ntsa thickness, qauv, kub, siab thiab orientation xam tau tias.Yog hais tias cov khoom tsis tau muaj cov tub ntxhais yug, qhov contraction yog correspondingly loj.
