IHydroxypropyl methylcellulose (HPMC) yikhompawundi yepolymer enyibilikayo emanzini ethathwa njengesixhobo sokwakha esihambelana nokusingqongileyo.
I-Biodegradability: I-HPMC ine-biodegradability elungileyo kwindawo yendalo, nto leyo ethetha ukuba inokuboliswa ngama-microorganisms phantsi kweemeko ezithile kwaye ekugqibeleni iguqulelwe kwizinto ezingenabungozi kokusingqongileyo. Ngokwahlukileyo koko, iiplastiki zemveli ezifana ne-polyethylene kunye ne-polypropylene kunzima ukuthotywa kwaye zihlale kwindawo engqongileyo ixesha elide, zibangela "ungcoliseko olumhlophe."
Impembelelo kwi-ikhosistim: Indlela eveliswa ngayo, isetyenziswe kwaye ilahlwe ngayo iplastiki ingcolisa imixokomelwano yokuphilisana kwezidalwa, ibeka emngciphekweni impilo yabantu kwaye iphazamisa nemozulu. Impembelelo yongcoliseko lweplastiki kwi-ikhosistim ibandakanya ungcoliseko lomhlaba, ungcoliseko lwamanzi, ukwenzakala kwizilwanyana zasendle kunye nezityalo, njl.njl. I-HPMC, kwelinye icala, ineempembelelo ezingephi kwixesha elide kwi-ikhosistim ngenxa yokubola kwayo.
Ukukhutshwa kwekhabhoni: Uphando olwenziwa liqela lika-Academician Hou Li'an lubonisa ukuba ukukhutshwa kwekhabhoni yeeplastiki ezibolayo (ezifana ne-HPMC) ebudeni bomjikelo wobomi bonke zimalunga ne-13.53% - 62.19% ngaphantsi kuneemveliso zeplastiki zemveli, ezibonisa amandla okuncitshiswa kwekhabhoni.
Ungcoliseko lweMicroplastic: Inkqubela-phambili yophando kwi-microplastics kwimo engqongileyo ibonisa ukuba impembelelo yamasuntswana eplastiki emhlabeni, kwintlenga, nakumanzi acwengileyo anokuba neempembelelo ezingalunganga zexesha elide kwezi zixokelelwano zendalo. Amasuntswana eplastiki anokuba yingozi ngokuphindwe ka-4 ukuya kwangama-23 emhlabeni kunaselwandle. Ngenxa yokubola kwayo, i-HPMC ayidali iingxaki eziqhubekayo zongcoliseko lwe-microplastic.
Imingcipheko yokusingqongileyo: Impembelelo yezoqoqosho yongcoliseko lweplastiki ibalulekile, kunye neendleko ezinxulumene nokucoca inkunkuma yeplastiki, ukuphumeza iinkqubo zokulawula inkunkuma, kunye nokujongana neempembelelo zokusingqongileyo nempilo yongcoliseko lweplastiki kubeka umthwalo wemali kuluntu noorhulumente. Njengemathiriyeli enokubola, i-HPMC inomngcipheko ophantsi wokusingqongileyo.
Uvavanyo lwempembelelo yokusingqongileyo: Ngokumalunga novavanyo lwempembelelo yokusingqongileyo, ukuveliswa kunye nokusetyenziswa kwe-HPMC kunempembelelo encinci kwi-atmosfera, amanzi kunye nomhlaba, kunye namanyathelo okuvelisa acocekileyo athathwe ngexesha lenkqubo yokuvelisa inokunciphisa ngakumbi impembelelo kokusingqongileyo.
Njengesixhobo sokusingqongileyo, i-HPMC ineenzuzo ezicacileyo ngaphezu kweeplastiki zemveli ngokwempembelelo yokusingqongileyo, ngakumbi malunga nokubola kwezinto eziphilayo, ukukhutshwa kwekhabhoni kunye nongcoliseko lwe-microplastic. Nangona kunjalo, impembelelo yokusingqongileyo ye-HPMC nayo kufuneka ivavanywe ngokubanzi ngokusekwe kwizinto ezifana nenkqubo yayo yokuvelisa, ukusetyenziswa kunye nokulahlwa kwayo.
