Itandukaniro riri hagati yimifuka ya PE na PP

Ibikoresho bitandukanye, PE: polyethylene, PP: polypropilene

PP ni plastike irambuye ya polipropilene, ni ubwoko bwa thermoplastique.Imifuka ya PP mubyukuri ni imifuka ya plastiki.Ibiranga imifuka ya PP ntabwo ari uburozi kandi ntiburyohe.Ubuso bwumufuka wa PP buroroshye kandi bubonerana, kandi bukoreshwa cyane mugupakira amavuta yo kwisiga, ibiryo, ibikinisho, imyambaro, ibikoresho, ibikoresho bya elegitoroniki, ibikoresho byinganda nizindi nganda.Ibara ryumufuka wa PP rirasobanutse, ryiza, gukomera, gukomera, kandi ntushobora gushushanya.Igiciro cyo gutunganya imifuka ya PP kirahendutse cyane, kandi ibiranga ni: byoroshye gutwika, urumuri rurashonga kandi rutonyanga, hejuru ni umuhondo naho hepfo ni ubururu, nyuma yo kuva mumuriro, haboneka umwotsi muke kandi gutwika birakomeza.

PE ni impfunyapfunyo ya polyethylene, ni ubwoko bwa resinoplastique resin ikozwe na polymerisation ya Ethylene.Polyethylene nta mpumuro nziza, idafite uburozi, yumva ari ibishashara, ifite ubushyuhe buke bwo kurwanya ubushyuhe (ubushyuhe bwo hasi burashobora kugera kuri -70 ～ -100 ℃), bufite imiti ihamye, kandi irashobora kwihanganira aside nyinshi na alkalis (ntibishobora kurwanya okiside) Acide), idashonga mumashanyarazi muri rusange mubushyuhe bwicyumba, kwinjiza amazi make, ibikoresho byiza byamashanyarazi;ariko polyethylene yunvikana cyane nibidukikije (ingaruka za chimique na mashini), kandi ifite ubukana buke bwo gusaza.Imiterere ya polyethylene iratandukanye bitewe nubwoko, ahanini bitewe n'imiterere ya molekile n'ubucucike.Uburyo butandukanye bwo kubyaza umusaruro burashobora gukoreshwa kugirango ubone ibicuruzwa bifite ubucucike butandukanye (0.91 ～ 0,96g / cm3).Byongeye, gupfunyika plastike yibikoresho bya PE birashobora kandi kwitwa umufuka wa PE.Menya ko igipfunyika cya plastiki gihuye neza nibiryo bigomba kuba bikozwe mubikoresho bya PE, bifite umutekano kumubiri wumuntu.
