Qhov sib txawv tseem ceeb ntawm copolymer thiab homopolymer polypropylene yog tias copolymer polypropylene yog tawv thiab ruaj khov dua li homopolymer polypropylene.
Polypropylene yog ib qho polymer ua los ntawm propene monomer. Nws yog linear hydrocarbon resin. Polypropylene muaj cov tshuaj formula (C3H6)n, qhov twg n yog tus naj npawb ntawm monomers hauv cov polymer. Ntxiv mus, cov khoom siv polymer no yog ib qho ntawm cov yas pheej yig tshaj plaws uas muaj hnub no. Polypropylene muaj qhov ntom ntom ntawm lwm cov khoom yas. Thaum polymerized, nws muaj peev xwm muaj peb txoj hauv paus saw hlau raws li txoj hauj lwm ntawm methyl pawg: atactic, isotactic, thiab syndiotactic polypropylene. Ob daim ntawv tseem ceeb ntawm polypropylene yog homopolymer daim ntawv thiab daim ntawv copolymer.
YCopolymer Polypropylene yog dab tsi?
Copolymer polypropylene yog ib hom polymer compound uas yog softer me ntsis tab sis muaj kev sib piv zoo zog. Ntxiv mus, nws yog tawv thiab ruaj khov dua li homopolymer daim ntawv ntawm polypropylene. Cov khoom siv polymer no muaj peev xwm ua kom muaj kev ntxhov siab zoo dua thiab qhov kub tsis tshua muaj zog piv rau homopolymer, tab sis ntawm tus nqi qis me me hauv lwm cov khoom tseem ceeb.
Daim duab 01: Isotactic Polypropylene
Peb tuaj yeem faib cov copolymer polypropylene rau hauv cov copolymer random thiab thaiv cov copolymer uas yog tsim los ntawm polymerization ntawm propene thiab ethane. Lub polypropylene random copolymer yog npaj los ntawm polymerization ntawm ethane thiab propene ua ke. Nws yog ib qho yooj yim thiab optically ntshiab cov khoom uas ua rau nws tseem ceeb nyob rau hauv daim ntawv thov yuav tsum tau transparency thiab cov khoom yuav tsum tau ib tug zoo heev tsos. Ntxiv mus, polypropylene thaiv copolymer muaj cov ntsiab lus siab ntawm ethane. Muaj ib qho qauv ntawm kev npaj ntawm co-monomer units hauv cov khoom no. Yog li ntawd, nws yog ib qho nyuaj thiab tsawg nkig piv rau random polypropylene copolymer.
Muaj lwm hom copolymer polypropylene uas tsis tshua muaj. Nws yog qhov cuam tshuam copolymer. Cov khoom siv no yog qhov tseem ceeb hauv kev siv xws li ntim khoom, khoom siv hauv tsev, kav dej, thiab ntu tsheb thiab hluav taws xob.
Y Homopolymer Polypropylene yog dab tsi?
Homopolymer polypropylene yog ib hom polymer compound uas sib piv tsis tshua muaj zog thiab tsis tshua muaj zog. Nws yog qib siv dav dav tshaj plaws. Feem ntau, cov khoom siv polymer no tsuas yog muaj cov polypropylene monomers nyob rau hauv semi-khoom crystalline khoom. Homopolymer polypropylene yog qhov tseem ceeb hauv kev ntim khoom, textiles, kho mob, kav, tsheb, thiab hluav taws xob siv.
Thaum xav txog cov khoom ntawm homopolymer polypropylene, nws muaj lub zog-rau-hnyav piv thiab muaj zog thiab muaj zog dua piv rau cov copolymer. Ntxiv mus, nws qhia tau hais tias cov tshuaj tiv thaiv zoo thiab weldability, uas ua rau nws cov khoom haum rau ntau cov qauv corrosion-resistant.
Qhov txawv ntawm Copolymer thiab Homopolymer Polypropylene yog dab tsi?
Homopolymer daim ntawv thiab daim ntawv copolymer yog ob lub ntsiab ntawm polypropylene. Copolymer polypropylene yog ib hom polymer compound uas yog mos mos tab sis muaj lub zog zoo dua, thaum homopolymer polypropylene yog ib hom polymer compound uas tsis yog tawv lossis ruaj khov raws li nws daim ntawv copolymer. Qhov sib txawv tseem ceeb ntawm copolymer thiab homopolymer polypropylene yog tias copolymer polypropylene yog tawv thiab ruaj khov dua li homopolymer polypropylene.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm copolymer thiab homopolymer polypropylene hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Copolymer vs Homopolymer Polypropylene
Copolymer polypropylene yog ib hom polymer compound uas yog me ntsis muag tab sis muaj lub zog zoo dua, thaum homopolymer polypropylene yog ib hom polymer compound uas tsis yog tawv lossis ruaj khov raws li nws daim ntawv copolymer. Qhov sib txawv tseem ceeb ntawm copolymer thiab homopolymer polypropylene yog tias copolymer polypropylene yog tawv thiab ruaj khov dua li homopolymer polypropylene. Tsis tas li ntawd, copolymer polypropylene muaj lub zog muaj zog ntau dua li homopolymer polypropylene.
