IHydroxypropyl methylcellulose (HPMC) iyisengezo esisetshenziswa kakhulu futhi sisetshenziswa kabanzi odakeni, kodwa umthelela waso ongaba khona emvelweni nawo udonse ukunaka.
Ukuwohloka kwemvelo: I-HPMC inekhono elithile lokuwohloka enhlabathini nasemanzini, kodwa izinga layo lokuwohloka lihamba kancane. Lokhu kungenxa yokuthi ukwakheka kwe-HPMC kuqukethe i-methylcellulose skeleton kanye namaketango aseceleni e-hydroxypropyl, okwenza i-HPMC ibe nokuzinza okuqinile. Kodwa-ke, ngokuhamba kwesikhathi, i-HPMC izoncishiswa kancane kancane ama-microorganisms nama-enzyme, futhi ekugcineni iguqulwe ibe izinto ezingezona ezinobuthi futhi imuncwe imvelo.
Umthelela endaweni ezungezile: Ezinye izifundo zibonise ukuthi imikhiqizo ewohlokayo ye-HPMC ingase ibe nomthelela othile ku-ecosystem emzimbeni wamanzi. Isibonelo, imikhiqizo yokuwohloka kwe-HPMC ingase ithinte ukukhula nokukhiqizwa kabusha kwezinto eziphilayo zasemanzini, ngaleyo ndlela kuthinte ukuzinza kwayo yonke i-ecosystem yasemanzini. Ukwengeza, imikhiqizo ewohlokayo ye-HPMC ingase futhi ibe nomthelela othile emsebenzini we-microbial kanye nokukhula kwezitshalo emhlabathini.
Ukulawulwa kobungozi bemvelo: Ukuze kwehliswe umthelela ongaba khona we-HPMC endaweni ezungezile, ezinye izinyathelo zingathathwa. Isibonelo, lapho uklama futhi ukhetha izinto ze-HPMC, cabanga ukusebenza kwayo kokucekela phansi bese ukhetha izinto ezisetshenziswayo ezinejubane lokuwohloka ngokushesha. Lungiselela ukusetshenziswa kwe-HPMC futhi unciphise inani lezinto ezisetshenziswayo, ngaleyo ndlela unciphise umthelela wayo endaweni ezungezile. Ukwengeza, ucwaningo olwengeziwe lungenziwa ukuze kuqondwe indlela yokucekelwa phansi kwe-HPMC kanye nomthelela wemikhiqizo ewohlokayo endaweni ezungezile, ukuze kuhlolwe kangcono futhi kulawuleke ubungozi bayo bemvelo.
Ukuhlola umthelela wendawo: Kwezinye izimo, kungase kudingeke ukuba kuhlolwe umthelela wendawo ongase uvezwe ngesikhathi sokukhiqizwa noma ukusetshenziswa kwe-HPMC. Isibonelo, lapho i-Anhui Jinshuiqiao Building Materials Co., Ltd. yenza umsebenzi wokulungisa nokwandisa ngomphumela wonyaka wamathani angu-3,000 we-HPMC, kwakudingeka kwenziwe ukuhlolwa komthelela kwezemvelo ngokuhambisana “Nezinyathelo Zokubamba Iqhaza Komphakathi Kwezemvelo. Ukuhlolwa Komthelela” futhi kushicilele ulwazi olufanele ukuze kuqinisekiswe ukuthi umthelela wephrojekthi endaweni ulawulwa ngendlela efanele.
Ukusetshenziswa endaweni ethile: Ukusetshenziswa kwe-HPMC ezindaweni ezithile nakho kudinga ukucabangela umthelela wayo kwezemvelo. Isibonelo, kusithiyo se-bentonite yenhlabathi engcoliswe ithusi, ukungezwa kwe-HPMC kunganxephezela ngokuphumelelayo ukuncishiswa kokusebenza kwayo kwe-anti-seepage endaweni yensimbi esindayo, ukunciphisa ukuhlanganiswa kwe-bentonite engcoliswe yethusi, igcine isakhiwo esiqhubekayo se-bentonite. , futhi ngokunyuka kwesilinganiso sokuxuba kwe-HPMC, izinga lokulimala kusithiyo liyancishiswa futhi ukusebenza kokulwa nokubona kuyathuthukiswa.
Nakuba i-HPMC isetshenziswa kakhulu embonini yezokwakha, umthelela wayo kwezemvelo awukwazi ukushaywa indiva. Ucwaningo lwesayensi kanye nezinyathelo zokuphatha ezifanele ziyadingeka ukuze kuqinisekiswe ukuthi ukusetshenziswa kwe-HPMC ngeke kube nemiphumela emibi emvelweni.
