I-Hydroxypropyl methylcellulose (HPMC) iyisengezo esivame ukusetshenziswa futhi isetshenziswa kabanzi ku-mortar, kodwa umthelela wayo ongaba khona emvelweni nawo udonsele ukunaka.
Ukubola: I-HPMC inekhono elithile lokubola enhlabathini nasemanzini, kodwa izinga layo lokubola lihamba kancane. Lokhu kungenxa yokuthi isakhiwo se-HPMC siqukethe uhlaka lwe-methylcellulose kanye ne-hydroxypropyl side chains, okwenza i-HPMC ibe nokuqina okuqinile. Kodwa-ke, ngokuhamba kwesikhathi, i-HPMC izobola kancane kancane yizinto ezincane nezincane kanye nama-enzyme, futhi ekugcineni iguqulwe ibe izinto ezingezona ubuthi futhi imuncwe yimvelo.
Umthelela emvelweni: Ezinye izifundo zibonise ukuthi imikhiqizo yokuwohloka kwe-HPMC ingaba nomthelela othile ohlelweni lwemvelo emzimbeni wamanzi. Isibonelo, imikhiqizo yokuwohloka kwe-HPMC ingathinta ukukhula nokuzala kwezinto eziphilayo zasemanzini, ngaleyo ndlela ithinte ukuzinza kohlelo lonke lwemvelo lwasemanzini. Ngaphezu kwalokho, imikhiqizo yokuwohloka kwe-HPMC ingaba nomthelela othile emsebenzini wamagciwane kanye nokukhula kwezitshalo enhlabathini.
Ukuphathwa kwezingozi zemvelo: Ukuze kuncishiswe umthelela ongaba khona we-HPMC emvelweni, kungathathwa izinyathelo ezithile. Isibonelo, lapho uklama futhi ukhetha izinto ze-HPMC, cabanga ngokusebenza kwayo kokuwohloka bese ukhetha izinto ngesivinini sokuwohloka esisheshayo. Lungiselela ukusetshenziswa kwe-HPMC futhi unciphise inani lezinto ezisetshenziswayo, ngaleyo ndlela unciphise umthelela wayo emvelweni. Ngaphezu kwalokho, ucwaningo olwengeziwe lungenziwa ukuze kuqondwe indlela yokuwohloka kwe-HPMC kanye nomthelela wemikhiqizo yokuwohloka emvelweni, ukuze kuhlolwe kangcono futhi kuphathwe izingozi zayo zemvelo.
Ukuhlolwa komthelela wezemvelo: Kwezinye izimo, kungadingeka ukuhlola umthelela wezemvelo ongase uvele ngesikhathi sokukhiqizwa noma ukusetshenziswa kwe-HPMC. Isibonelo, lapho i-Anhui Jinshuiqiao Building Materials Co., Ltd. yenza iphrojekthi yokuvuselela nokwandisa ngomkhiqizo waminyaka yonke wamathani angu-3,000 e-HPMC, kwakudingeka kwenziwe ukuhlolwa komthelela wezemvelo ngokuhambisana "Nezinyathelo Zokubamba Iqhaza Komphakathi Ekuhlolweni Komthelela Wezemvelo" futhi kushicilelwe ulwazi olufanele ukuqinisekisa ukuthi umthelela wephrojekthi emvelweni ulawulwa ngokufanele.
Ukusetshenziswa ezindaweni ezithile: Ukusetshenziswa kwe-HPMC ezindaweni ezithile kudinga futhi ukucabangela umthelela wayo emvelweni. Isibonelo, emgoqweni wenhlabathi-bentonite ongcoliswe yithusi, ukungezwa kwe-HPMC kungabuyisela ngempumelelo ekunciphiseni ukusebenza kwayo kokungangeni kwamanzi endaweni enesihlabathi esindayo, kunciphise ukuhlanganiswa kwe-bentonite engcoliswe yithusi, kugcine isakhiwo esiqhubekayo se-bentonite, futhi ngokwanda kwesilinganiso sokuxuba se-HPMC, izinga lomonakalo emgoqweni liyancishiswa futhi ukusebenza kokungangeni kwamanzi kuyathuthuka.
Nakuba i-HPMC isetshenziswa kabanzi embonini yokwakha, umthelela wayo kwezemvelo awunakushaywa indiva. Ucwaningo lwesayensi kanye nezinyathelo zokuphatha ezifanele ziyadingeka ukuqinisekisa ukuthi ukusetshenziswa kwe-HPMC ngeke kube nemiphumela emibi emvelweni.
