Dab tsi yog polypropylene? -Ploperties, kev siv thiab cov txiaj ntsig ntawm polypropylene
Dab tsi yog polypropylene (pp)? Polypropylene yog ib thermopoplastic polymer ua los ntawm cov tshuaj pleev roj-propylene monomers thiab yog ib qho ntawm cov khoom siv yas feem ntau hauv ntiaj teb. Vim nws cov khoom lag luam thiab lub cev, polypropylene coj txoj haujlwm tseem ceeb hauv kev lag luam, kev kho mob, tsev neeg thiab ntim zaub mov noj. Hauv tsab xov xwm no, peb coj mus rau hauv-tob saib ntawm cov khoom tseem ceeb ntawm polypropylene, nws cov ntawv thov tseem ceeb thiab nws cov txiaj ntsig.
Cov Khoom Yooj Yim ntawm Polypropylene
Dab tsi yog polypropylene? Nyob rau hauv cov nqe lus ntawm cov qauv tshuaj, polypropylene yog cov polymer tsim los ntawm qhov ntxiv polymerisation ntawm propylene monomers. Nws cov qauv molecular yog ib yam zoo ib yam thiab feem ntau muaj nyob hauv ib daim ntawv semi-crystalline. Qhov kev ua yeeb yam no thiab crystalline qauv muab polypropylene ib tug xov tooj ntawm cov khoom siv lub cev zoo heev, xws li ntom ntom nti, qis tshuaj tsis txaus ntseeg thiab tshuaj lom neeg ruaj khov. Polypropylene lub ntsiab lus melting yog feem ntau ntawm 130 ° C thiab 171 ° C, uas tso cai rau nws kom nyob ruaj khov nyob rau ntawm qhov kub. Nrog qhov ntom ntom ntawm kwv yees li 0.9 g / cmÃ, polypropylene yog sib dua dua li ntau lwm cov plastics xws li polyethylene thiab muaj kev tiv thaiv corrosion zoo heev.
Cov ntawv tseem ceeb rau polypropylene
Dab tsi yog polypropylene? Dab tsi yog nws cov ntawv thov hauv ntau yam kev lag luam? Vim yog nws cov ntau yam khoom, polypropylene yog siv nyob rau hauv ntau cov kev siv. Hauv kev lag luam ntim, polypropylene yog siv nyob rau hauv cov khoom loj rau cov khoom lag luam xws li ntim zaub mov, lub kaus mom thiab cov yeeb yaj kiab. Nws cov tshuaj tiv thaiv thiab noo noo tiv taus ua kom nws zoo tagnrho rau cov zaub mov ntim, ua kom muaj kev nyab xeeb rau kev nyab xeeb thiab txee lub neej. Nyob rau hauv lub rooj tog zaum hauv tsev, polypropylene yog siv los ua cov rooj tog, ntim khoom thiab cov khoom siv hluav taws xob, vim nws yooj yim, nrog rau nws txoj kev tu thiab txij nkawm. Ntxiv mus, hauv kev lag luam kho mob, polypropylene yog siv los ua cov koob txhaj tshuaj, kev sim cov leeg vim tias cov khoom siv kho mob zoo thiab cov tshuaj tiv thaiv kab mob antimicrobial.
Polypropylene cov txiaj ntsig thiab kev txhim kho yav tom ntej
Thaum nws los txog dab tsi polypropylene yog, nws cov txiaj ntsig tseem ceeb tshaj plaws suav nrog cov kub thiab tshuaj tiv thaiv cua, nrog rau cov nqi ntau lawm. Polypropylene lub siab yaj lub siab tau tso cai rau nws siv tau kub dua yam tsis muaj teeb meem ntawm distortion lossis yaj. Nws cov tshuaj zoo heev tiv thaiv polypropylene kom nyob ruaj khov thiab tsis corrode thaum raug rau cov kua qaub, alkalis thiab cov kuab tshuaj organic. Polypropylene qhov yooj yim thiab tsis tshua muaj nqi ntau lawm ua rau nws siv thoob plaws hauv ntau yam khoom hauv lub neej txhua hnub.
Raws li ib puag ncig kev paub txog ib puag ncig loj hlob, polypropylene lub recyclability tau dhau los ua qhov txiaj ntsig tseem ceeb. Niaj hnub niaj hnub thev naus laus zis tso cai rau kev rov ua dua cov khoom siv polyprropylene, uas tau txo cov pov tseg ntawm cov peev txheej thiab ib puag ncig pa paug. Yog li ntawd, kev txhim kho yav tom ntej ntawm polypropylene cov khoom yuav them rau kev tiv thaiv ib puag ncig thiab kev ruaj khov, thiab ntxiv txhim kho nws cov kev ua tau zoo.

Dab tsi yog polypropylene khoom? Cov ncauj lus kom ntxaws ntxaws hauv daim ntawv no qhia tias polypropylene yog ib thermoplicity polymer nrog ntau yam khoom siv thiab ntau yam zoo. Nws lub siab melting taw tes, tshuaj lom neeg kuj, lub teeb yuag, thiab tus nqi qis dua ua rau tseem ceeb hauv ntau qhov kev lag luam. Nrog rau kev txhim kho ntawm cov thev naus laus zis ib puag ncig, polypropylene raug poised rau kev siv ntxiv rau yav tom ntej. Yog tias koj tab tom nrhiav kev ua haujlwm zoo thiab cov khoom siv roj pheej muaj nqis, polypropylene yog qhov kev xaiv tsim nyog txiav txim siab.
