Qhov sib txawv tseem ceeb ntawm elastomer thiab plastomer yog tias elastomers qhia elasticity, whereas plastomers qhia ob qho tib si yas thiab elasticity.
Polymers yog cov ntaub ntawv macromolecular uas muaj ntau qhov rov ua dua tshiab hu ua monomers. Elastomers thiab plastomers yog cov polymers muaj cov khoom tshwj xeeb. Plastomers, txawm li cas los xij, yog cov khoom siv nrog cov khoom zoo dua qub vim yog kev sib xyaw ntawm ob qho tib si elastic thiab yas cwj pwm.
Elastomer yog dab tsi?
Elastomers yog hom polymers uas muaj cov yam ntxwv tseem ceeb ntawm elasticity. Cov no yog cov ntaub ntawv zoo li roj hmab, uas feem ntau yog amorphous polymers. Qhov ntawd txhais tau tias tsis muaj cov qauv txiav txim hauv lawv. Cov cuab yeej elastic ntawm elastomers yog vim tsis muaj zog txaus Van Der Waal ntawm cov saw hlau polymer (uas ua rau cov qauv tsis zoo txaus). Yog tias Van der Waals rog ntawm cov saw hlau polymer tsis muaj zog, nws muab cov polymer yooj. Ib yam li ntawd, yog tias cov polymer muaj cov qauv tsis sib haum, nws tso cai rau cov polymer hloov tau yooj yim dua. Txawm li cas los xij, txhawm rau kom cov polymer hloov tau yooj yim, nws yuav tsum muaj qee qhov kev sib txuas sib txuas ib yam.

Peb tuaj yeem txheeb xyuas qhov zoo elastomer los ntawm kev soj ntsuam nws cov yas ntws; ib tug zoo elastomer tsis undergo yas ntws. Qhov ntawd txhais tau hais tias cov duab ntawm elastomer yuav hloov pauv thaum muaj kev ntxhov siab, tab sis nws yuav tau txais nws cov duab qub thaum qhov kev ntxhov siab tau txo qis. Ib qho piv txwv zoo ntawm qhov no yog cov txheej txheem roj hmab vulcanization. Ntuj roj hmab ib leeg nyhav dhau los ntawm cov yas ntws. Vulcanization yog cov txheej txheem uas cov sulfur cross-links tau qhia rau cov roj hmab ntuj. Qhov no ua rau txo qis ntawm cov yas ntws thiab tso cai rau cov polymer rov qab los rau nws cov qauv qub thaum ncab thiab tso tawm.
Elastomers muaj nyob rau hauv ob hom xws li thermoplastic thiab thermoset elastomers. Thermoplastic elastomers yog cov ntaub ntawv uas yaj thaum rhuab. Thermoset elastomers yog cov ntaub ntawv uas tsis yaj thaum rhuab.
Plastomer yog dab tsi?
Y Plastomer yog ib hom polymer uas muaj ob qho tib si elastic thiab yas cwj pwm. Hauv lwm lo lus, plastomers yog cov polymers uas muaj cov khoom sib xyaw ntawm elastomers thiab yas. Cov ntaub ntawv no muaj cov khoom zoo li roj hmab nrog lub peev xwm los ua cov yas. Tsis tas li ntawd, lo lus plstomer cov ntaub ntawv tsim ib qho kev sib xyaw ntawm cov yas thiab elastomer. Qee qhov tseem ceeb plastomers suav nrog ethylene-alpha olefin copolymer. Cov ntaub ntawv no muaj txiaj ntsig zoo li cov khoom siv polymer los muab cov khoom tshwj xeeb hauv kev ntim khoom, molded thiab extruded khoom, hlau, thiab cable, thiab foaming compounds.

Cov txiaj ntsig ntawm kev siv cov plastomers suav nrog kev ua kom cov khoom ntim tau yooj yim vim kev txhim kho toughness, clarity thiab sealing kev ua tau zoo, txhim kho kev cuam tshuam lub zog thiab yoog raws, thiab lwm yam. Lawv tuaj yeem siv los tsim cov hlau thiab cable vim lawv lub cev muaj zog. khoom thaum ua ke nrog cov fillers thiab additives.
Qhov txawv ntawm Elastomer thiab Plastomer yog dab tsi?
Qhov sib txawv tseem ceeb ntawm elastomer thiab plastomer yog tias elastomers qhia elasticity, whereas plastomers qhia ob qho tib si yas thiab elasticity. Qee qhov piv txwv ntawm elastomers suav nrog cov roj hmab ntuj, cov roj hmab neoprene, buna-s thiab buna-n. Qee qhov tseem ceeb plastomers suav nrog ethylene-alpha olefin copolymer. Ntxiv mus, elastomers yog siv thaum yuav tsum tau yooj yim thaum lub plasomers siv thaum ob qho tib si, yooj thiab toughness yuav tsum tau.
Hauv qab infographic qhia txog qhov sib txawv ntawm elastomer thiab plastomer hauv daim ntawv tabular.
Summary – Elastomer vs Plastomer
Polymers yog cov ntaub ntawv macromolecular uas muaj ntau qhov rov ua dua tshiab hu ua monomers. Elastomers thiab plastomers yog ob hom polymers. Qhov sib txawv tseem ceeb ntawm elastomer thiab plastomer yog tias elastomers qhia elasticity, whereas plastomers qhia ob qho tib si yas thiab elasticity.
