I-HPMC, eyaziwa nangokuthi i-hydroxypropylllylyly, isengezo esisebenza kahle kakhulu esisetshenziswa kabanzi embonini yezokwakha, ikakhulukazi ekwakheni udonga lwamaPretty. Udonga uPretty lusetshenziselwa ukulungiselela kanye nezindonga zeleveli ngaphambi kokupenda, ngaleyo ndlela kuqedwe ngokuphelele.
Abakhi abaningi baye baba nezinkinga ngokuhlanza phambili phambili. I-SAG yenzeka lapho uPuture eqala ukuslayida odongeni ngenxa yesisindo sawo. Lokhu kuphumela ekuqedeni okungalingani futhi okungafanele okuthatha isikhathi esiningi nomzamo ukulungisa. Kodwa-ke, abakhi bathole isisombululo ngokungeza i-HPMC edongeni uPutty, esiza ukuthuthukisa ukumelana kwe-SAG kanye nekhwalithi ephelele yomkhiqizo wokugcina.
Kunezizathu eziningana zokuthi kungani i-HPMC iyisengezo esisebenzayo kangaka. Okokuqala, isebenza njengomuntu omkhulu, okusho ukuthi kusiza ukukhulisa ukubonakala kwezinto ezisetshenziselwa ukubeka impahla. Lokhu kukhuphuka okwandayo kwenza kube nzima ngokwezinto ezisetshenziselwa ukushelela izindonga futhi kusiza ukunamathela okungcono ukuze uthathe indawo. I-putty ethuthukisiwe yensizwa nayo ikuvumela ukugcwalisa ama-microcracks kanye nemithambo emincane ezindongeni, ukuhlinzeka ngobushelelezi, ngisho nangaphezulu komhlaba. Lesi sici futhi sisiza ukunciphisa inani le-putty elidingekayo ukumboza indawo enikeziwe, okuholele ekuxazululeni izindleko ezingabizi kakhulu.
Okwesibili, i-HPMC idlala indima ebalulekile ekulawuleni ijubane lokomisa odongeni uPutty. Isivinini sokomisa sithinta ngqo ukumelana kwe-putty, kanti i-putty eyomisa kancane iqinile kakhulu futhi ayilula ukugcwala. I-HPMC isiza ukulawula isilinganiso sokuhwamuka kwamanzi ezindaweni ezi-putty, okuthinta isikhathi sayo sokusoma. Lokhu kuhlinzekela kuphumela ku-tutty ezinzile futhi engaguquki eyomile ngokulinganayo, kunciphisa ithuba lokugcwala.
I-HPMC nayo ingasetshenziswa ukuthuthukisa ukunamathela phakathi kodonga uPretty kanye ne-substrate. I-adhesion ibhekisa ezingeni lapho impahla ebeka khona inamathela ebusweni lapho isetshenziswa khona. I-HPMC ingathuthukisa kakhulu ukunamathela ngoba ihlinzeka ngefilimu evikelayo ebusweni, ethuthukisa ukunamathela kwe-putty ku-substrate.
Ngaphezu kwalokho, i-HPMC ingasiza futhi ukugcina umswakama ezintweni zodonga ama-putty. Yize amanzi ephakathi nendawo ephakathi kokucutshungulwa kokuqina nokuqina, futhi imbangela eyinhloko yokuqhekeka nokuhlaselwa kwezinto ezibonakalayo lapho amanzi ephuma ngokushesha okukhulu. I-HPMC isiza ukugcina umswakama ezintweni ezisetshenziselwa isikhathi eside, okuvumela ukuthi i-putty ihlale ngokulinganayo futhi yomile ngaphandle kokugcoba.
Ukufingqa, i-HPMC iyisengezo esibalulekile futhi esisebenzayo edongeni uPutty, odlala indima ebalulekile ekwandiseni impahla elwa nama-polling putty. Ngokulawula kwayo okuqina, ukulola isilinganiso, ukuthuthukiswa kokunamathela kanye nezindawo zokugcina amanzi, i-HPMC inikeza abakhi ikhambi elisebenzayo ezinkingeni ze-SAG futhi lithuthukisa ikhwalithi ephelele yomkhiqizo wokugcina. Inzuzo ayigcini nje ngokubushelelezi, ukuqeda okungaphezulu okuzinzile, kepha futhi nasekusebenzeni kwezindleko zekhambi. Ngakho-ke, kuyadingeka ukubona nokugcizelela iqhaza elingenakufinyeleleka kwe-HPMC embonini yezokwakha.
