Polypropylene ipurasitiki inogona kuparara here?
Mumwe munhu akabvunza kana polypropylene ipurasitiki inoparara?Saka regai nditange ndanzwisisa kuti chii chinonzi purasitiki inoparara?Purasitiki yakasvibiswa rudzi rwechigadzirwa chinosangana nezvinodiwa zvakasiyana-siyana, uye kushanda kwayo hakushanduki panguva yekuchengetedza.Mushure mekushandisa, inogona kuderedzwa munzvimbo yakasikwa kuita zvinhu zvisingakuvadzi kune zvakatipoteredza.Plastiki iyi ipurasitiki inoparara.
Mapurasitiki anoparara akakamurwa kuita mapurasitiki anoomeswa, biodegradable mapurasitiki, nezvimwewo, anowanzo shandiswa mapurasitiki anoshatisa anosanganisira PHA, APC, PCL, zvichingodaro.Polypropylene haisi yeboka remapurasitiki anoparara.Kubva pane tsananguro iri pamusoro yemapurasitiki anoparara, tinogona kuziva kuti musiyano unokosha wemapurasitiki anoparara ndewekuti anogona kushatiswa munzvimbo yakasikwa, uye zvinhu zvinoshatisa hazvikuvadzi uye hazvina kukuvadza kune zvakatipoteredza.Polypropylene particles inowanzowedzerwa ne antioxidants uye degradants, izvo zvakaoma kuderedza.Zvinotora makore 20-30 kuti adzikise, uye mukugadzirisa achabudisa chepfu, kusvibisa zvakatipoteredza uye ivhu.Kana iri polypropylene yakachena, zvigadzirwa zvayo hazvigone kusangana nezvinodiwa zvakasiyana-siyana, hazvina kugadzikana zvakanyanya, uye zviri nyore kuderedzwa uye oxidized.
Nokudaro, polypropylene haisi purasitiki inoparara.Ko polypropylene inogona kuve biodegradable plastiki?Mhinduro ndihongu.Kuchinja iyo kabhoni yemukati yepolypropylene inogona kuita nguva yekushatisa yePP plastiki kutenderedza mazuva makumi matanhatu-600.Kuwedzera hushoma hwephotoinitiator uye zvimwe zvinowedzera kuPP plastiki zvinogona kukurumidza kushatisa polypropylene.Munyika dzekuMadokero, iyi fotodegradable PP zvinhu yakashandiswa zvakanyanya mukurongedza chikafu uye kugadzira fodya, asi nekuita uye nekusimudzira zvirambidzo zvepurasitiki munyika dzakasiyana siyana.Kuvandudzwa kwemapurasitiki anogona kucheneswa kuchapfuura zvine mutsindo.
