Zina mwa zinthu zofunika kwambiri za polypropylene ndi izi: 1. Kukana Mankhwala: Maziko ndi ma asidi osungunuka sagwira ntchito mosavuta ndi polypropylene, zomwe zimapangitsa kuti ikhale chisankho chabwino pamabotolo okhala ndi zakumwa zotere, monga zotsukira, zinthu zothandizira oyamba, ndi zina zambiri. 2. Kutanuka ndi Kulimba: Polypropylene imagwira ntchito motakasuka pamitundu ina ya kupotoka (monga zipangizo zonse), koma imakhalanso ndi kusintha kwa pulasitiki kumayambiriro kwa njira yosinthira, kotero nthawi zambiri imaonedwa ngati chinthu "cholimba". Kulimba ndi mawu auinjiniya omwe amatanthauzidwa ngati kuthekera kwa chinthu kupotoka (mwa pulasitiki, osati motakasuka) popanda kusweka. 3. Kukana Kutopa: Polypropylene imasunga mawonekedwe ake itatha kupotoka, kupindika, ndi/kapena kupindika kwambiri. Kapangidwe kake ndi... -
Deta ya malo imachepetsedwa molakwika, ndipo PVC imayatsidwa.
Lolemba, deta ya malo inapitirira kukhala yocheperako, zomwe zinakhudza kwambiri zomwe anthu ankayembekezera pakufuna. Pofika kumapeto, mgwirizano waukulu wa PVC unatsika ndi oposa 2%.

Kusanthula kwa momwe makampani opanga PVC akupitira patsogolo ku North America.
North America ndi dera lachiwiri lalikulu kwambiri padziko lonse lapansi lopanga PVC. Mu 2020, kupanga PVC ku North America kudzakhala matani 7.16 miliyoni, zomwe zikutanthauza 16% ya kupanga PVC padziko lonse lapansi. M'tsogolomu, kupanga PVC ku North America kupitilirabe kukwera. North America ndiye dziko lalikulu kwambiri padziko lonse lapansi logulitsa PVC, zomwe zimapangitsa 33% ya malonda apadziko lonse lapansi a PVC. Chifukwa cha kuchuluka kokwanira kwa zinthu zomwe zimatumizidwa ku North America, kuchuluka kwa zinthu zomwe zimatumizidwa sikudzawonjezeka kwambiri mtsogolo.

Kodi Polypropylene (PP) ndi chiyani?
Polypropylene (PP) ndi thermoplastic yolimba, yolimba, komanso yopangidwa ndi kristalo. Imapangidwa kuchokera ku propene (kapena propylene) monomer. Utomoni wa hydrocarbon wolunjika uwu ndiye polima wopepuka kwambiri pakati pa mapulasitiki onse ogulitsa. PP imabwera ngati homopolymer kapena copolymer ndipo imatha kuwonjezeredwa kwambiri ndi zowonjezera. Imagwiritsidwa ntchito mu ma CD, magalimoto, zinthu zogulira, zamankhwala, mafilimu opangidwa ndi pulasitiki, ndi zina zotero. PP yakhala chinthu chosankhidwa, makamaka mukafuna polima wamphamvu kwambiri (monga, motsutsana ndi Polyamide) mu ntchito zaukadaulo kapena kungofuna phindu la ndalama m'mabotolo opangira zinthu (motsutsana ndi PET).
