I-HPMC okanye i-Hydroxypropyl Methylcellulose yi-ether ye-cellulose engeyiyo ionic esetyenziswa kakhulu kushishino lokwakha.Ifunyenwe kwi-cellulose ye-polymer yendalo kwaye iguqulwe ngamachiza ukuvelisa i-cellulose ether.I-HPMC licandelo elibalulekileyo lodaka lomxube owomileyo, ukunika le mixube ukusebenza okugqwesileyo kunye nokuqina.Kwesi sikhokelo, siza kuxoxa ngokusetyenziswa kwe-HPMC kumxube owomileyo wodaka kunye nendlela enokuphucula ngayo ukusebenza kwale mixube yodaka.
Ukusetyenziswa kweHPMC kudaka olomileyo oluxubeneyo:
1. Umthamo ogqwesileyo wokugcinwa kwamanzi: I-HPMC inomthamo olungileyo wokugcinwa kwamanzi, nto leyo ibaluleke kakhulu kudaka oluxubeneyo olomileyo.Xa ixutywe nodaka lomxube owomileyo, lufunxa ukufuma kwaye ngokuthe ngcembe lukhuphe njengoko umxube ubeka.Oku kukhutshwa ngokuthe ngcembe kwamanzi kuqinisekisa ukuba udaka lufumana ukufuma okwaneleyo ukuze lubekwe kwaye lube lukhuni, lunciphisa umngcipheko wokuqhekeka kunye nokushwabana.
2. Ukuphucula ukusebenza: I-HPMC iphucula ukusebenza kodaka oluxutyiweyo ngokubonelela nge-lubrication elungileyo.Kwakhona kwandisa ukunamathela kodaka kwi-substrate.Oku kuphucula ukusebenza kwenza kube lula ukusebenzisa udaka ngokulinganayo kwi-substrate kunye nokunciphisa umngcipheko wemixube engahambelaniyo.
3. Nciphisa ukuthoba: Xa ugalelwe kumphezulu othe nkqo, udaka oluxubeneyo owomileyo luhlala ludilika okanye luhexe, nto leyo ekhokelela kulwakhiwo olungalinganiyo.I-HPMC inciphisa i-sag yodaka ngokwandisa ukuhambelana kunye ne-viscosity yomxube, iyenze ibe zinzileyo.
4. Ukuphucula ukubambelela: I-HPMC iphucula iimpawu zokubambelela kwi-dry-mixed mortar kwaye inceda ukukhusela ukwahlukana kunye nokopha komxube.Ukunyuka kokubambisana komdaka kuphinda kuqinisekise ukuba kuhambelana kakuhle ne-substrate, ukunciphisa umngcipheko wokuqhawula kunye nokuqhekeka.
5. Ukuphucula ukuguquguquka: I-HPMC iphucula ukuguquguquka kodaka oluxutyiweyo oluxutywe, okwenza luxhathise ngakumbi kwi-shrinkage, i-crack, kunye nemozulu.Oku kuguquguquka okunyukayo kwenza ukuba udaka lomelele kwaye luhlale ixesha elide, nakwindawo ezingqongileyo ezinzima.
I-HPMC yinxalenye ebalulekileyo yodaka lomxube owomileyo kwaye idlala indima ebalulekileyo ekusebenzeni kwayo.Iimpawu zayo eziyingqayizivele, ezifana nokugcinwa kwamanzi, ukuphuculwa kokusebenza, ukunciphisa i-sag, ukudibanisa okuphuculweyo kunye nokuguquguquka, kwenza kube yinto efanelekileyo yokuxuba umxube owomileyo.I-HPMC ayiphuculi nje kuphela ukusebenza kodaka lomxube owomileyo, kodwa iphucula ukuqina kwayo, iyenza ibe noqoqosho ngakumbi.Ngophando oluqhubekayo kunye nophuhliso, i-HPMC ikhawuleza ibe sisisombululo esikhethiweyo kumxube owomileyo wodaka kushishino lokwakha.Ndiyathemba ukuba esi sikhokelo siya kukunceda uqonde ukusetyenziswa kwe-HPMC kudaka lomxube owomileyo.
