I-Hydroxypropyl Methylcellulose (HPMC) iyisengezo esisetshenziswa kakhulu futhi isetshenziswa kabanzi ngodaka, kodwa umthelela wawo ongaba khona emvelweni ubuye wadonsela ukunaka.
I-Biodegradeabilibility: I-HPMC inekhono elithile lokuwohloka enhlabathini nasemanzini, kepha izinga lokuwohloka kwalo lihamba kancane. Lokhu kungenxa yokuthi ukwakheka kwe-HPMC kuqukethe amathanga aseceleni we-methylcellose kanye namaketanga aseceleni kwe-hpdroxypropyl, okwenza i-HPMC ibe nokuqina okuqinile. Kodwa-ke, ngokuhamba kwesikhathi, kancane kancane, i-HPMC izodonswa kancane kancane ngama-microorganisms nama-enzyme, futhi ekugcineni yaguqulwa yaba yizinto ezingeyona into enobuthi futhi yamukele imvelo.
Umthelela emvelweni: Ezinye izifundo zikhombise ukuthi imikhiqizo yokucekelwa phansi ye-HPMC ingaba nomthelela othile ohlelweni lwemvelo emzimbeni wamanzi. Isibonelo, imikhiqizo yokucekelwa phansi ye-HPMC ingathinta ukukhula kanye nokukhiqizwa kwezinto eziphilayo zasemanzini, ngaleyo ndlela kuthinte ukuqina kwalo lonke izwe lase-aquatic. Ngaphezu kwalokho, imikhiqizo yokucekelwa phansi ye-HPMC nayo ingaba nomthelela othile kumsebenzi we-microbial kanye nokukhula kwezitshalo enhlabathini.
Ukulawulwa Kwengozi Yezemvelo: Ukuze kuncishiswe umthelela ongaba khona we-HPMC emvelweni, ezinye izinyathelo zingathathwa. Isibonelo, lapho uklama futhi ukhetha izinto ze-HPMC, cabanga ukusebenza kwayo kokuwohloka bese ukhetha izinto zokwenza kahle ngejubane lokonakala ngokushesha. Lungiselela ukusetshenziswa kwe-HPMC futhi unciphise inani lezinto zokwakha ezisetshenzisiwe, ngaleyo ndlela kunciphise umthelela wayo emvelweni. Ngaphezu kwalokho, ukucwaninga okwengeziwe kungenziwa ukuze uqonde indlela yokuhlanza i-HPMC kanye nomthelela wemikhiqizo yokuwohloka emvelweni, ukuze uhlole kangcono futhi uphathe ubungozi bawo bezemvelo.
Ukuhlolwa Komthelela Wezemvelo: Kwezinye izimo, kungahle kudingekile ukuhlola umthelela wezemvelo okungenziwa kwenziwa ngesikhathi sokukhiqiza noma ukusetshenziswa kwe-HPMC. Isibonelo, lapho i-Anhui Jinshuiao wokwakha izinto Co, Ltd yenziwe iphrojekthi yokwakhiwa kabusha neyanda yonyaka ephumayo yonyaka yamathani angama-3,000 e-HPMC, kwakudingeka enze ukuhlolwa komthelela wezemvelo ngokuya nge "Izinyathelo zokubamba iqhaza komphakathi ku-Imvelo Ukuhlolwa komthelela "nokushicilela imininingwane efanele ukuqinisekisa ukuthi umthelela wephrojekthi esemvelweni ulawulwa kahle.
Isicelo ezindaweni ezithile: Ukusetshenziswa kwe-HPMC ezindaweni ezithile nakho kudinga ukubheka umthelela wayo wezemvelo. Isibonelo, esivimbisweni senhlabathi esingcolisiwe se-bentonite, ukungezwa kwe-HPMC kungasinxephezela ngempumelelo ukufakwa kokusebenza kwalo kwe-anti-seepage endaweni yensimbi esindayo, kunciphise ukuhlanganiswa kwe-bentonite engcoliswe yi-petronite, gcina isakhiwo esiqhubekayo se-bentonite , futhi ngokwanda kwesilinganiso sokuxuba kwe-HPMC, izinga lomonakalo kwisithiyo sehlisiwe futhi ukusebenza kwe-anti-seepage kuyathuthuka.
Yize i-HPMC isetshenziswa kabanzi embonini yezokwakha, umthelela wayo wezemvelo awunakunakwa. Ukucwaninga kwesayensi kanye nezindlela zokuphatha ezinengqondo zidingeka ukuqinisekisa ukuthi ukusetshenziswa kwe-HPMC ngeke kube nemiphumela emibi emvelweni.
