Polypropylene yog cov yas polymer nrog cov tshuaj formula C3H6. Nws siv ntau qhov chaw sib txawv, ob qho tib si hauv kev lag luam thiab hauv cov khoom siv khoom siv, thiab nws tuaj yeem siv ob qho tib si ua cov yas ua thiab ua fiber ntau. Cov yas no feem ntau siv rau cov khoom noj khoom haus, tshwj xeeb yog cov uas xav tau lub tshuab ntxuav tais diav.
Lub npoo ntawm cov pob zeb polypropylene yog piv siab heev rau lwm yam, ntawm 320 ° F (160 ° C), uas txhais tau hais tias cov dej kub siv thaum ntxuav tais diav yuav tsis ua cov khoom ntim tawm ntawm cov yas no. Qhov no yog sib txawv nrog polyethylene , lwm nrov yas rau ntim, uas muaj ib qho qis dua melting point. Polypropylene kuj yog ib qho yooj yim ntxiv rau kev ntxiv dyes rau, thiab nws yog feem ntau siv los ua fiber ntau nyob rau hauv ntaub pua tsev uas yuav tsum tau muaj kev sib zog thiab kav, xws li siv rau cov pas dej da dej los yog hauv cov hoob kawm me me golf. Tsis zoo li nylon , uas yog feem ntau siv los ua fiber ntau rau rugged carpeting, nws tsis ntub dej, ua nws zoo rau qhov twg nws yuav tsum tau tas li mus txog ya raws.
Kev tshawb fawb yog sib txuas nrog polypropylene, raws li kev xyaum ua tej yam sib txawv rau kev sib txuas ntawm nws. Qee qhov kev sim no yog lo lus cog tseg ntawm kev pom zoo tshiab ntawm cov yas, nrog cov tshiab thiab muaj kev sib txawv ntawm cov qauv ceev xwm txheej uas feem ntau yog siv rau. Cov tshiab elastic versions yog rubbery heev, ua rau lawv txawm tias ntau tshaj ntawm cov tawv nqaij tawg thiab qhib ntau yam kev siv rau ib lub hnab yas pervasive.
Polypropylene tsis yog khov kho raws li polyethylene, tab sis nws muaj txiaj ntsig uas ua rau nws muaj kev xaiv zoo hauv qee lub sijhawm. Ib qho ntawm cov xwm txheej no yog tsim cov hinges los ntawm ib lub yas, xws li lub hau yas ntawm lub tebchaws . Txij lub sij hawm, plastics hnav tawm ntawm qhov kev ntxhov siab ntawm qhov pib thiab kaw, thiab thaum kawg yuav tawg. Polypropylene tiv thaiv qhov kev nyuab siab no heev, thiab nws yog cov yas uas feem ntau siv rau cov hau thiab lub kaus mom uas yuav tsum tau muaj txoj hlua khawm.
Zoo li ntau yam yas, polypropylene tau siv kev siv tsis txawj zoo, thiab nws txoj kev loj hlob tsis tau qeeb txij thaum nws cov kev nrhiav pom. Seb puas siv cov pwm ua pwm, cov ntaub pua chaw, lub tsheb qhov chaw, los yog cov ntim cia , nws yog ib lub tswv yim ntawm lub ntiaj teb tau los ua ib ncig.
