IHydroxypropyl methylcellulose (HPMC) iyinhlanganisela ye-polymer encibilika emanzini ngokuvamile ethathwa njengempahla yokwakha evumelana nemvelo.
I-Biodegradability: I-HPMC inokubola okuhle kwemvelo endaweni yemvelo, okusho ukuthi ingaboliswa ama-microorganisms ngaphansi kwezimo ezithile futhi ekugcineni iguqulwe ibe izinto ezingenabungozi emvelweni. Ngokuphambene, amapulasitiki endabuko afana ne-polyethylene ne-polypropylene kunzima ukuwohloka futhi ahlale endaweni ezungezile isikhathi eside, okubangela "ukungcola okumhlophe."
Umthelela kuma-ecosystem: Indlela ipulasitiki ekhiqizwa ngayo, esetshenziswa ngayo futhi ilahlwa ngayo ingcolisa imvelo, ibeka impilo yabantu engozini futhi ikhubaze isimo sezulu. Umthelela wokunukubezeka kwepulasitiki ku-ecosystem uhlanganisa ukungcoliswa komhlabathi, ukungcoliswa kwamanzi, ukulimala kwezilwane zasendle nezitshalo, njll. I-HPMC, ngakolunye uhlangothi, inomthelela omncane wesikhathi eside ku-ecosystem ngenxa yokubola kwayo.
Ukukhishwa kwekhabhoni: Ucwaningo olwenziwa yithimba le-Academician Hou Li'an lubonisa ukuthi ukukhishwa kwekhabhoni kumapulasitiki abolayo (njenge-HPMC) phakathi nawo wonke umjikelezo wempilo cishe kungaphansi ngo-13.53% - 62.19% kunemikhiqizo yepulasitiki yendabuko, okubonisa amandla amakhulu okunciphisa isikhutha.
Ukungcoliswa Kwepulasitiki: Intuthuko yocwaningo lwama-microplastics endaweni ezungezile ibonisa ukuthi umthelela wezinhlayiya zepulasitiki emhlabathini, inhlabathi, namanzi ahlanzekile ungase ube nomthelela omubi wesikhathi eside kulezi zinhlelo zemvelo. Izinhlayiya zepulasitiki zingase zibe yingozi ngokuphindwe ka-4 kuya kwezingu-23 emhlabeni kunasezilwandle. Ngenxa yokubola kwayo, i-HPMC ayidali izinkinga eziqhubekayo zokunukubezeka kwe-microplastic.
Izingozi zemvelo: Umthelela wezomnotho wokungcoliswa kwepulasitiki ubalulekile, nezindleko ezihambisanayo zokuhlanza imfucumfucu yepulasitiki, ukusebenzisa izinhlelo zokulawula imfucuza, nokubhekana nemithelela yemvelo nempilo yokungcoliswa kwepulasitiki okubeka umthwalo wezezimali emiphakathini nakohulumeni. Njengempahla ebolayo, i-HPMC inezingozi eziphansi zemvelo.
Ukuhlolwa komthelela kwezemvelo: Mayelana nokuhlolwa komthelela kwezemvelo, ukukhiqizwa kanye nokusetshenziswa kwe-HPMC kunomthelela omncane emkhathini, emanzini nasenhlabathini, futhi izinyathelo zokukhiqiza ezihlanzekile ezithathwe phakathi nenqubo yokukhiqiza zingase zinciphise umthelela emvelweni.
Njengempahla ehambisana nemvelo, i-HPMC inezinzuzo ezisobala ngaphezu kwamapulasitiki endabuko ngokomthelela wendawo, ikakhulukazi mayelana nokubola kwezinto eziphilayo, ukukhishwa kwekhabhoni kanye nokungcoliswa kwe-microplastic. Kodwa-ke, umthelela wemvelo we-HPMC nawo udinga ukuhlolwa ngokuningiliziwe ngokusekelwe ezintweni ezifana nenqubo yayo ethile yokukhiqiza, ukusetshenziswa kanye nokulahlwa kwayo.
