Nws yog qhov paub zoo tias cov khoom siv raw ntawm cov ntaub thaiv nyom kev lag luam yog polypropylene, thiab qee zaus yuav muaj qee qhov polyethylene PE. Txawm hais tias peb txhua tus paub tias cov khoom siv raw no yog dab tsi thiab hom kev thov nws yog dab tsi, puas muaj qhov tob txaus rau nws txoj kev nkag siab? Peb paub dab tsi txog nws cov khoom siv tshuaj? Los ntawm cov nram qab no series ntawm kev tsom xam thiab kev lim ntshav qhia rau peb saib lub ntsej muag tseeb ntawm cov ntaub ntawv nyom PP PP.
Poly (propylene) yog cov thermoplastic resin npaj los ntawm polymerization ntawm propylene. Nws tuaj yeem muab faib ua peb qhov kev teeb tsa: isometric, tsis xwm yeem thiab intermetric. Cov khoom lag luam siv isometric ua cov khoom tseem ceeb. Qee lub sij hawm polypropylene, suav nrog cov copolymer ntawm propylene nrog me me ntawm ethylene, muaj nyob rau hauv cov ntaub pua tsev, thiab cov zej zog no feem ntau yuav raug siv dua. Cov khoom siv yas no, feem ntau yog cov xim tsis muaj xim, tsis muaj ntxhiab thiab tsis muaj tshuaj lom, ntau tus phooj ywg xav tias tsis muaj tshuaj lom, ntawm no tuaj yeem qhia meej rau koj,
Tom qab dhau qhov kev ntsuam xyuas yooj yim saum toj no, peb tau ua tib zoo saib xyuas cov ntaub ntawv raw cov ntaub ntawv los tiv thaiv nyom
