Iipropathi ezizodwa ze-HPMC zenza isithako esiphambili kwi-raat enesidima esiphezulu

I-HydroxyPOpyl Methylcelcelsele (i-HPMC) yi-polymer yendalo eqhelekileyo esetyenziswa kwimizi-mveliso eyahlukeneyo kubandakanya ukutya, amayeza nolwakhiwo. Kwishishini le-PoASS, i-HPMC ithathwa njengesithako esinqwenelekayo ngenxa yepropathi eyahlukileyo, esenza isithako esingafanelekanga kwimali esebenzayo. I-COASSSONS eyenziwe kwi-HPMC ixabisa ixabiso labo elihle, ukunamathela kunye nokuchasana kwamanzi.

I-1. I-HPMC ineepropathi ezigqwesileyo zamanzi. Kungenxa yokuba yi-volymer ye-hydrophilic, intsingiselo inomtsalane onamandla kwiimolekyuli zamanzi. Xa i-HPMC yongezwa kwi-cayishini, inceda ukugcina umswakama ixesha elide, ekubaluleke kakhulu ukugcina umgangatho kunye nokuzinza kwengubo. I-COASSSS EKUNGAVIYO IINGOZI ZOKUGCINWA ZAMANZI AMANZI AMANYE AMANQAKU AMANYANA AYENZIWE OKANYE OYENZIWEYO AKWENZA UKUZE UZE UVULE UKUZIPHATHA OKANYE UKUFUNDA. Ke ngoko, i-HPMC iphucula ukumelana kwamanzi kwengqumbo, kukwenze ilungele ukusetyenziswa kwiindawo ezinobunzima.

I-2. I-HPMC inepropathi ebalaseleyo yefilimu. Iimolekyuli ze-HPMC zineentambo ezinde ezibavumela ukuba zenze iifilimu ezomeleleyo xa kudibene nezinye izinto zokuhambisana ezinjengee-resins kunye ne-pigments. Oku kuqinisekisa ukuba ipeyinti eyenziwe kwi-HPMC ine-adhec elungileyo kwaye inamathele kakuhle kumphezulu isetyenziswa. Ipropathi yokwakha ifilimu ye-HPMC ikwaphucula ukuqina kwengqumbo, ukwandisa ukumelana nokunganyangeki kumonakalo kunye ne-abrasion.

I-3. I-HPMC ihambelana nokuhambelana nezinye iingubo. Sisithako esiguquguqukayo esinokongezwa kwizinto ezahlukeneyo zokudibana ngaphandle kokuchaphazela intsebenzo yayo. Oku kuthetha ukuba ukurhweba okwenziwe kwi-HPMC kunokwenziwa ngokwezifiso ukuhlangabezana neemfuno ezithile, njengokuxhathisa kwamanzi, glass okanye ukuthungwa. Ukongeza, i-HPMC inokwenziwa ngokuviwa okwahlukileyo, ivumela ukudalwa kwengubo ngepropathi eyahlukileyo.

I-4. I-HPMC inobuhlobo okusingqongileyo kwaye inetyhefu esezantsi. Oku kukwenza ukuba kungabikho nto ikhuselekileyo yokusetyenziswa kwi-cayings ezinxibelelana nokutya, amanzi okanye ezinye izinto ezibuthathaka. I-Coasthings yenziwe kwi-HPMC ayinakuphila kwaye ayikho isoyikiso kwindalo esingqongileyo, ibenzele ukhetho olubonakalayo lwabathengi abaziisimo.

I-5. I-HPMC kulula ukuyisebenzisa kwaye ichaphazele. Iza ngeendlela ezahlukeneyo ezinje ngomgubo okanye isisombululo kwaye inyibilikiswe ngokulula emanzini. Oku kwenza ukuba kube lula ukuxuba nezinye izinto ezihlambulayo kwaye kuqinisekise ukuba iingubo ezenziwe kwi-HPMC zinesityholo esiguquguqukayo kunye notyelelo. Ukongeza, i-HPMC yindawo engeyiyo i-ionic, oko kuthetha ukuba ayichaphazeleki yi-PH yoqulunqwa lokupeyinta. Oku kwenza ukuba isithako esizinzileyo esinokusetyenziswa kwifom ye-acidic okanye i-alkaline yepeyinti.

I-6. I-HPMC isebenza ngokugqibeleleyo phantsi kweemeko ezahlukeneyo zobushushu kunye neemeko zokufuma. I-Coasthings yenziwe kwi-HPMC ayiyi kuba yi-brittle okanye iqhekekile xa ityhilwe kubushushu obuphantsi. Zikwagcina nepropathi yabo xa ityhilwe kwiimeko eziphakamileyo zokufuma. Oku kwenza ukuba iingubo ezenziwe kwi-HPMC ilungele ukusetyenziswa kwiindawo ezahlukeneyo, kubandakanya iimeko zemozulu eziqatha.

I-7. I-HPMC inomelele kakuhle kwizinyibilikisi eziphilayo. Le propati yenza i-HPMC ifakwe ngokulula kwi-cayishini esekwe kwi-Solvent. Ukongeza, kuba i-HPMC yindawo eyi-Ionic ye-Ionic, ayichaphazeli iipropathi zesinyibilikisi okanye uzinzo lokuqulunqwa kwe-COOHE. Oku kwenza i-HPMC i-HPMC isithako esifanelekileyo kwizinto ezahlukeneyo zokucanda, kubandakanya ukusula okusekwe ngokusisiseko.

Iipropathi ezizodwa ze-HPMC zenza isithako esibalulekileyo kwi-cayidings ephezulu. Ukugcinwa kwayo kwamanzi, ukwenziwa kwefilimu, ukuhambelana, ubuhlobo bokusingqongileyo, ukulunga kokusebenza, ukuSebenza ngokuSebenza, ukuSebenza kunye nokuSebenza nokuSebenza kunye nokuSebenza kweSoMubiday kwenza ukuba isetyenziswe ngeendlela ezahlukeneyo zokudibanisa. I-COASSISWEYO YENZIWE I-HPMC ixabiswe ngenxa yokunamathela kwabo ngokuncomekayo, ukuxhathisa kwamanzi kunye nokuqina, kubenza balungele ukusetyenziswa kwiindawo ezinobunzima. Ngenxa yokungaguquguquki, i-HPMC inokwenziwa ngokwezifiso ukufezekisa iimfuno ezithile, zenza ukhetho oludumileyo kwimveliso yempahla. Lilonke, i-HPMC sisiqulatho sokusebenza esiphezulu esibaluleke kakhulu kwimpumelelo yeengubo ezisebenzayo eziphezulu.
