PE vs PE
Qhov zoo ntawm polypropylene (PP):
Thaum tshav kub kub tsis kam: PP muaj qhov kub thiab txias thiab tuaj yeem tiv taus qhov kub siab dua yam tsis muaj deforming lossis tso tawm cov khoom tsis zoo.
Rigidity thiab cuam tshuam tsis kam: PP lub raj mis dej muaj qhov nruj thiab cuam tshuam, thiab tsis yooj yim tawg lossis deform.
Cov tshuaj tiv thaiv corrosion zoo: PP tuaj yeem tiv thaiv kev yaig ntawm ntau cov tshuaj thiab tsis yooj yim rau corroded.
Sealing kev ua tau zoo: PP muaj kev sib khi zoo, uas tuaj yeem tiv thaiv cov fwj dej kom tsis txhob tawg.
Recyclability: PP cov ntaub ntawv tuaj yeem siv tau thiab rov siv dua, uas yog qhov zoo rau kev tiv thaiv ib puag ncig.
Qhov zoo ntawm polyethylene (PE):
Toughness thiab Durability: PE lub raj mis dej muaj qhov zoo toughness thiab durability, tsis yooj yim rau tawg los yog deform.
Tus nqi qis: cov khoom siv PE kuj pheej yig, thiab cov nqi tsim khoom kuj tsawg.
Chemical stability: PE muaj kev ruaj ntseg rau cov tshuaj siv tshuaj thiab tsis yooj yim corroded los ntawm cov tshuaj lom neeg.
Kev rwb thaiv tsev hluav taws xob zoo: PE muaj cov khoom siv hluav taws xob zoo thiab tsim nyog rau cov khoom siv hluav taws xob lossis cov fwj dej hauv qhov chaw them nqi.
Disadvantages ntawm polypropylene (PP):
Sib npaug nyuaj: PP kuj nyuaj piv rau lwm yam ntaub ntawv, thiab tej zaum yuav tsis mos thiab xis txaus.
Opacity: PP feem ntau yog opaque, ua rau nws tsis pom cov kua theem hauv lub thawv.
Qhov tsis zoo ntawm polyethylene (PE):
Tsis tshua muaj hluav taws kub tsis kam: PE muaj cov cua sov tsis zoo thiab tsis haum rau khaws cov kua kub kub.
Tsawg rigidity: Piv nrog rau lwm cov ntaub ntawv, PE yog mos thiab tej zaum yuav yooj yim deformed.
