1. Ukuphucula ukugcinwa kwamanzi kwidaka
IHydroxypropyl methylcellulose (HPMC) i-arhente egqwesileyo yokugcina amanzi efunxa ngokufanelekileyo kwaye igcine amanzi ngokwenza i-uniform network structure kudaka. Oku kugcinwa kwamanzi kunokwandisa ixesha lokuphuphuma kwamanzi kudaka kunye nokunciphisa izinga lokulahlekelwa kwamanzi, ngaloo ndlela kulibazisa isantya sokusabela kwe-hydration kunye nokunciphisa umthamo wokuqhekeka kweentanda ezibangelwa kukuphuma kwamanzi ngokukhawuleza. Kwangaxeshanye, ixesha elide elivulekileyo kunye nexesha lokwakha likwanceda ekuphuculeni umgangatho wokwakha nokunciphisa amathuba okuqhekeka.
2. Ukuphucula ukusebenza kunye ne-rheology yodaka
I-HPMC inokulungelelanisa i-viscosity yodaka, iyenze kube lula ukusebenza. Olu phuculo aluphuculi kuphela ulwelo kunye nokusebenza kodaka, kodwa luphucula ukunamathela kunye nokugubungela kwi-substrate. Ukongeza, i-AnxinCel®HPMC inokunciphisa ukwahlula kunye nokuphuma kwamanzi kwi-mortar, yenza amacandelo omdaka asasazwe ngokulinganayo, ugweme ukugxilwa kwengcinezelo yendawo, kunye nokunciphisa ngokufanelekileyo amathuba okuqhekeka.
3. Ukuphucula ukubambelela kunye nokumelana nokuqhekeka kodaka
Ifilimu ye-viscoelastic eyenziwe yi-HPMC kwi-mortar ingazalisa iipores ngaphakathi kodaka, iphucule ukuxinwa kodaka, kwaye ikhulise ukunamathela kodaka kwi-substrate. Ukuqulunqwa kwale filimu akugcini nje ukuqinisa isakhiwo esipheleleyo sodaka, kodwa kunempembelelo yokuthintela ekwandiseni i-microcracks, ngaloo ndlela iphucula kakhulu ukuchasana nokuqhekeka komdaka. Ukongeza, i-polymer structure ye-HPMC inokusasaza uxinzelelo ngexesha lokunyanga udaka, ukunciphisa uxinzelelo olubangelwa yimithwalo yangaphandle okanye i-deformation ye-substrate, kwaye incede ukukhusela ukuphuhliswa okuqhubekayo kweentanda.
4. Lawula i-shrinkage kunye ne-plastic shrinkage yodaka
Umdaka uqhelene nokuqhekeka kweentanda ngenxa yokuphuma kwamanzi ngumphunga ngexesha lenkqubo yokomisa, kwaye ipropathi yokugcina amanzi ye-HPMC inokulibazisa ukulahleka kwamanzi kunye nokunciphisa ukucutha komthamo obangelwa kukuncipha. Ukongeza, i-HPMC nayo inokunciphisa umngcipheko wokuqhekeka kweentanda zeplastiki, ngakumbi kwinqanaba lokuqala lokumisela udaka. Ilawula isantya sokufuduka kunye nokuhanjiswa kwamanzi, inciphisa uxinzelelo lwe-capillary kunye noxinzelelo lwangaphezulu, kwaye inciphisa ngokufanelekileyo amathuba okuqhekeka kumphezulu wodaka.
5. Phucula ukuxhathisa ukunyibilika kodaka
Ukongezwa kwe-HPMC nako kunokomeleza ukuxhathisa ukunyibilika komkhenkce. Ukugcinwa kwayo kwamanzi kunye nokukwazi ukwenza ifilimu kunceda ukunciphisa izinga lokukhenkceza kwamanzi kumdaka phantsi kweemeko zokushisa eziphantsi, ukuphepha umonakalo kwisakhiwo sodaka ngenxa yokwandiswa komthamo weekristale zeqhwa. Ukongeza, ukwenziwa ngcono kwesakhiwo sepore sodaka yi-HPMC kunokunciphisa ifuthe lemijikelo yokunyibilika komkhenkce kuxhathiso lokuqhekeka kodaka.
6. Yandisa ixesha le-hydration reaction kwaye ulungise i-microstructure
I-HPMC yongeza ixesha lokusabela kwe-hydration yodaka, ivumela iimveliso zesamente zokugalela amanzi ukuba zizalise imingxuma yodaka ngokulinganayo ngakumbi kwaye iphucule ukuxinana kodaka. Oku kulungiswa kwe-microstructure kunokunciphisa ukuveliswa kweziphene zangaphakathi, ngaloo ndlela kuphuculwe ukuxhathisa kokuqhekeka ngokubanzi kodaka. Ukongeza, ikhonkco le-polymer ye-HPMC inokwenza intsebenziswano ethile kunye nemveliso ye-hydration, iphucule ngakumbi amandla kunye nokumelana nokuqhekeka kodaka.
7. Ukuphucula ukuchasana kwe-deformation kunye neempawu zokufunxa amandla
I-AnxinCel®HPMC inika udaka ukuguquguquka okuthile kunye nokuchasana nokuguqulwa, ukuze ikwazi ukuziqhelanisa kakuhle nemeko yangaphandle xa iphantsi kwamandla angaphandle okanye utshintsho lobushushu. Le propati yokufunxa amandla ibaluleke kakhulu ekuxhathiseni ukuqhekeka, okunokunciphisa ukubunjwa kunye nokwandiswa kweentanda kunye nokuphucula ukuqina kwexesha elide lodaka.
HPMC iphucula ukuxhathisa kokuqhekeka kodaka kwiinkalo ezininzi ngokugcina amanzi awodwa, ukuncamathela kunye nobuchule bokwenza ifilimu, kubandakanywa nokuphucula ukusebenza kodaka, ukunciphisa ukuncipha kunye nokuqhekeka kweentanda zeplastiki, ukomeleza ukunamathela, ukwandisa ixesha elivulekileyo kunye nobuchule bokuchasana nomkhenkce. Kwizinto zokwakha zale mihla, i-HPMC iye yaba yingxubevange ebalulekileyo yokuphucula ukuxhathisa kokuqhekeka kodaka, kwaye amathuba esicelo sayo abanzi kakhulu.
