I-HydroxyPOpyl Methylcelcelsulose (HPMC) sisifo esibalulekileyo seseluplose i-Etestly esetyenziswe ngokubanzi kwizinto zokwakha, ngakumbi kumngxunya owomileyo. I-HPMC ayiphumi nje ukusebenza kokwakha kodaka, kodwa iphucula iipropathi zomzimba kunye neekhemikhali zemveliso egqityiweyo.
Iimpawu ezisisiseko ze-HPMC
I-HPMC yi-ionic ye-ionic ye-ionic ye-ionic ye-polymer eguqulwe ngekhemikhali kwi-seluplose yendalo. Ipropathi yayo ephambili ibandakanya ukuzola kwamanzi ngokufanelekileyo, iipropathi ezikhalizayo zefilimu, i-adhesion, i-tickeng kunye nokuzinza. Ezi propati zenza i-HPMC igqibelele kwizicelo ezahlukeneyo, ngakumbi ekuqulunqweni kodaka kumzi-mveliso wokwakha.
Indima ye-HPMC ngodaka olwahlukileyo
Ukugcinwa kwamanzi okuphuculweyo
I-HPMC ineepropathi ezifanelekileyo zokugcina amanzi kwaye inokuphucula umgangatho wokugcina amanzi obukhoboka. Ingquba emanzini kwaye iyenza isisombululo esifana nejeli, esinokunciphisa ukuvela kwamanzi kunye nokulahleka kwamanzi, ngaloo ndlela sigcina isidenge. Le ndlela yokugcinwa kwamanzi ibaluleke kakhulu kwinkqubela phambili yokuhamba-hlula-hlula, ukunceda ukuphucula amandla okuzala komhlaba kwaye kuncitshiswe umngcipheko wokuqhekeka.
Isiphumo sokutyibilika
Xa i-HPMC ichithwe emanzini, iya kwenza ulwelo lwe-colloidal ye-viscoidal, ukwandisa i-viscosity yodaka. Isiphumo sobukhulu sinokuphucula ukumelana kwe-SAG yodaka, kokwenza kube lula ukufaka kwaye kubume udaka ngexesha lolwakhiwo. Oku kunceda abakhi bawenze i-fert kwindawo ethe nkqo njengeendonga ukuthintela udaka ukuba lube nokuhamba okanye ukuwa.
Ukuphucula ukusebenza
Kuba i-HPMC iphucula i-thambisa kunye neplasitiki yodaka, yenza kube lula ukuxuba, impompo kunye nokusasazeka. Olu phuculo lwenza ukuba ukwakhiwa kube lula ngakumbi kwaye kwandisa ukusebenza ngokwakha. Kwangelo xesha, kunokuphucula i-Thrixotropy yodaka, esenza udaka ngocorn xa iphantsi kwamandla eshishina kwaye iluncedo xa kusenziwa imisebenzi yokwakha.
Ukuphucula ububi
Isakhiwo se-colloidal eyenziwe yi-HPMC kwi-mpmc kwi-Condirn inokuphucula amandla aphezulu phakathi kodaka kunye nezinto ezisesikweni. Lo mhlatho ophuculweyo ubalulekile kwizicelo ezinje nge-tiles eboleka udaka okanye udaka lokuthintela i-inshorni ukuthintela umbandela ekutyibilikeni kwaye ubazise.
Ukulawulwa kokuqhekeka
Ukususela i-HPMC inokuphucula kakhulu ukugcinwa kwamanzi, kuyanceda ukunciphisa ukumiswa kweendawo zokuhamba kwangoko. Ukongeza, iipropathi zayo zokuthambisa kunye ne-Bonding zikwasasaza uxinzelelo kwaye zinciphise imingxunya ebangelwe kukuguquka kobushushu okanye i-shrintage yendawo ekhuselweyo.
Uhlalutyo lwee-Metrim
Ulwakhiwo lweMolekyuli kunye nokugcinwa kwamanzi
Isakhiwo se-geculari se-HPMC siqulathe inani elikhulu lamaqela e-hydrophilic, njengemidlalo ye-hydroxyl kunye ne-mayipxy. La maqela enza imingxunya ye-hydrogen ngeemolekyuli zamanzi, enika i-HPMC amandla anamandla okufumana kwaye agcine amanzi. Xa i-HPMC ichithwe emanzini, iyenza ubume bothungelwano lweenethiwekhi ezintathu ezigcina amanzi ngokusebenzisa i-adsorption kunye nokubopha kwamachiza.
Ukuqulunqwa kweColloid kunye nokutyibilika
Ebudeni, i-HPMC iyanyibilikisa ukwenza isisombululo seColoidal. Esi sisombululo se-colloidal sigcwalisa i-voids e-fanser kwaye yonyusa i-viscosity iyonke yodaka. I-HPMC molecular thakethe i-foage yenethiwekhi ezinzileyo ngokusebenzisana nokuntywila kunye nokunxulumana ngokwasemzimbeni, ngaloo ndlela yandisa kakhulu umzobo wodaka.
Ukwenza i-yebrication kunye nokusebenza
I-HPMC molecring Stoans isebenza njengeoyile kububele. Banokwenza ifilimu ethambisayo kumphezulu wamasuntswana, ukunciphisa ukungqubana phakathi kwamasuntswana. Esi siphumo se-qubination Yenza ukuba udaka luvuselele kwaye lube njalo, luphucula ukugungqa kolwakhiwo.
I-Adheion engafundanga kunye nokudibana
Ubume be-Colloidal ye-HPMC buza kwenza ifilimu emdaka emva komomo. Le film inqabileyo inokuthobela ngqo kumphezulu wezinto ezisisiseko kwaye iphucule amandla aphezulu phakathi kodaka kunye nezinto ezisesikweni. Esi siphumo sibaluleke kakhulu ekuphuculeni iipropati zodaka lodaka.
IMIYALELO Imizekelo ye-HPMC
I-Tile Bround Arr
Kwi-ceiramic ye-ceirac ibophelela izifakazi, ukugcinwa kwamanzi kunye nokugcina iipropathi ze-HPMC kuqinisekisa ukuba udaka lunemithi ye-cerayic, ekhulisa iithayile ze-ceramic xa i-tearamic iwele ngexesha lenkqubo yokomisa.
Ukubethwa
Kwindawo yokufakelwa phantsi, isiphumo esihle se-HPMC senza kube lula ukusebenzisa udaka eludongeni kwaye uthintele udaka ukuba luwe. Iipropathi zayo ezilungileyo zokugcina amanzi ziya kunciphisa umngcipheko wokuqhekeka kwi-Player.
Ukuthathwa kwenqanaba lokuzimela
Ngomgangatho wokuziqokelela, i-Thtrixipy kunye neepropathi ze-HPMC ziqinisekisa ukuba udaka lunepropathi elungileyo lokuzilinganisa xa uhamba, ngelixa ugcina imisebenzi efanelekileyo xa isebenza khona.
Indima ye-HPMC kwi-hirt-racrage oxutyweyo inomdla. Ayiphuluki kuphela intsebenzo yodaka ngokuphucula ukugcinwa kwamanzi kunye neepropathi ezinkulu, kodwa kukuphucula isiphumo sokwakha ngokuphucula ukusebenza kunye nokunamathela. Ukusetyenziswa kwe-HPMC kuye kwenza udaka luphume lusetyenziswe ngokubanzi kulwakhiwo lwale mihla, luphucule kakhulu umgangatho kunye nokusebenza kakuhle kolwakhiwo. Kwixa elizayo, ngokuqhubela phambili phambili kwiTekhnoloji yeZongezelelo kwiTekhnoloji yeZinto, isiphumo se-HPMC siya kwandiswa kwaye siphuculwe.
