Polypropilene ni plastiki ibora?
Umuntu yabajije niba polypropilene ari plastiki yangirika?Reka rero mbanze nsobanukirwe niki plastiki yangirika?Plastike yangirika ni ubwoko bwibicuruzwa byujuje ibisabwa bitandukanye, kandi imikorere yabyo ntabwo ihinduka mugihe cyo kubika.Nyuma yo kuyikoresha, irashobora kwangirika mubidukikije karemano mubintu bitangiza ibidukikije.Iyi plastiki ni plastiki yangirika.
Plastike yangirika igabanijwemo plastike ishobora gufotorwa, plastiki ibinyabuzima ishobora kwangirika, nibindi, plastiki ikoreshwa cyane yangiza harimo PHA, APC, PCL, nibindi.Polypropilene ntabwo iri mubyiciro bya plastiki yangirika.Duhereye ku bisobanuro byavuzwe haruguru bya plastiki yangirika, dushobora kumenya ko itandukaniro ryibanze rya plastiki yangirika ari uko rishobora kwangirika mu bidukikije, kandi ibintu byangirika ntacyo bitwaye kandi nta byangiza ibidukikije.Ibice bya polipropilene byongewemo hamwe na antioxydants na degradants, bigoye kuyitesha agaciro.Bifata imyaka 20-30 kugirango biteshwe agaciro, kandi murwego rwo kurekura uburozi, bwangiza ibidukikije nubutaka.Kubijyanye na polypropilene yuzuye, ibicuruzwa byayo ntibishobora kuba byujuje ibyangombwa bisabwa bitandukanye, ntibihungabana cyane, kandi byangiritse kandi byoroshye.
Kubwibyo, polypropilene ntabwo ari plastiki yangirika.Polypropilene irashobora guhinduka plastike ibora?Igisubizo ni yego.Guhindura karubone ya polypropilene irashobora gukora igihe cyo kwangirika kwa plastike ya PP muminsi 60-600.Ongeramo umubare muto wa fotoinitiator nibindi byongera kuri plastike ya PP birashobora gutesha agaciro polypropilene.Mu bihugu by’iburengerazuba, ibi bikoresho bya PP bifotorwa byakoreshejwe cyane mu gupakira ibiryo no mu itabi, ariko hamwe no gushyira mu bikorwa no guteza imbere ibihano bya pulasitike mu bihugu bitandukanye.Iterambere rya plastike ibinyabuzima bizarenga ubuziranenge.
