Indima ye-Hydroxypropyl Methylcelceluplose e-Utoty

I-Hydroxypropyl Methylcelcelsele (i-HPMC) yi-polymer eguquguqukayo kunye ne-polymer eguquguqukayo edlala indima ebalulekileyo kwizicelo ezahlukeneyo, kuquka iindlela zokumisa. I-DOTTY yinto esetyenziswayo ekwakhiweni nasekwakheni izicelo ezahlukeneyo zeshishini zokugcwalisa, zokutywina kunye nokuthamba.

I-HydroxypropyTelmethylcelcelcelcelcelcelose i-selsulose ye-selsulose i-syntheled ukusuka kwi-sellulose, i-polymer yendalo ifunyenwe kwiindonga zeseli zezityalo. Inkqubo yemveliso ibandakanya ukunyanga ukunyanga i-sellulose nealkalis kunye neearhente zokuphuma. I-HPMC esemphunga ngumgubo omhlophe okanye ongekho mhlophe onyibilikayo onyibilikayo emanzini kwaye wenza isisombululo se-viscous esibonakalayo.

I-2. Iipropathi zeHydroxypropyl Methylcelcelcelose:

Ngaphambi kokuba iphonononge indima ye-HPMC e-ITPMC, kuyimfuneko ukuze uqonde izinto eziphambili ze-HPMC:

I-Solibuz yamanzi: I-HPMC inyibilikiswa yamanzi kwaye yenze isisombululo esicacileyo nesizinzileyo xa sidityaniswe namanzi. Le propati iququzelela ukufezekisa ukungqinelana okufunekayo kwifom yokubeka.

I-thermal gallge: i-HPMC iphantsi kwenkqubo yokuthintela umva, oko kuthetha ukuba ukubonakala kwayo kunyuka xa kushushu kwaye kuyancipha xa kupholile. Le ndawo ixabiseke kwizicelo ze-putty apho utshintsho lobushushu lunokwenzeka ngexesha lokuxuba kunye nokusetyenziswa.

Ukuqulunqwa kwefilimu: I-HPMC yenza ifilimu emncinci, eguqukayo xa isetyenziselwa umphezulu. Le mpahla inegalelo kwi-Betty's Abetheration kunye nokudibana, ukuphucula ukusebenza kwayo njengempahla yonyango.

I-Thickener: i-HPMC isebenza njenge-tickener esebenzayo, ibonelela ngothintelo olufunekayo kunye nokungqinelana kwendlela yokubeka. Amandla olawulo alawulwayo asasaza ngokulula kwaye anyibilike kumphezulu.

3. Indima ye-Hydroxypropyl Methylcelcelgalose e -toty:

Ukuphuculwa kokuphuculwa: I-HPMC yandisa ukusebenza kwe-putty ngokudlulisela ukwenziwa kwengqondo kunye nokuhlekisa. Iipropathi ezilawulekayo kunye nokugcinwa kwamanzi ukuququzelelwa kwesicelo kunye nokusasazeka kwe-platty kwindawo ezahlukeneyo.

Ukugcinwa kwamanzi: Enye yemisebenzi ephambili ye-HPMC kwifom ye-putty kukukwazi ukugcina amanzi. Eli nqaku lithintela i-putty ekubeni iphume kwangoko, kuqinisekisa ixesha elaneleyo lokufaka isicelo, ukubumba kunye nokugqiba. Ukugcinwa kwamanzi okuphuculweyo kuyanceda ukuphucula ubumbethe kunye ne-propes.

Ukunamathela kunye nokudibana: I-HPMC ikhuthaza ukubambelela ngokwenza ifilimu emdaka kumphezulu we-subtate, ukukhuthaza ulwalamano phakathi kwe-poty kunye nezinto ezisisiseko. Ukongeza, iipropathi ezihlanganisiweyo ze-HPMC nceda ukuphucula amandla apheleleyo kunye nokuqina kwe-putty emva kwesicelo.

Ukunciphisa i-shrinkage: I-Shrinkage yingxaki eqhelekileyo kwifom yokubeka kwaye inokubangela ukuba uqhekekelo kunye nokungafezeki kumphezulu. I-HPMC inceda ukunciphisa ukuncitshiswa ngokulawula ukuphuma kwamanzi ngexesha lenkqubo yokomisa, kukhokelela ekungazinzisweni okuzinzileyo okunganyangekiyo ekuchitheni.

Ixesha eliphuculweyo: Iipropathi ze-thermalges ye-HPMC inokulawula ixesha elimisiweyo kwifom yokubeka. Oku kubaluleke kakhulu kwizicelo apho kufuneka ixesha elithile lexesha lokubekwa nokunyanga.

4. Izibonelelo zokusebenzisa i-hydroxypropyl methylcelgalose e -toty

Ukusebenza kwezinto eziguquguqukayo: I-HPMC inokufakwa kwiindlela ezahlukeneyo zokwenziwa, zenza ukuba zilungele izicelo ezahlukeneyo ezinje ngodonga olunamanzi, i-platy yenkuni kunye nodonga olungaphandle nodonga olungaphandle.

Ukuqina okuphuculweyo: Iipropathi zokuhlaselwa kwe-HPMC kunye ne-HPMC kunye nezona zinto zingenayo zinegalelo kwixesha elide kunye nokusebenza kwe-putty, ukunciphisa amathuba okuba neziphene kunye neziphene ngokuhamba kwexesha.

Ukuhambelana nezinye ii -opultives: I-HPMC iyahambelana noluhlu lweezongezo kunye neefilimu ezixhaphakileyo ezisetyenziswayo kwifom yokubeka, ukuvumela ukuba iimfuno ezithile zomsebenzi.

Ukuqwalaselwa kokusingqongileyo: Njengokukhutshwa kweseli, i-HPMC ithathelwa ingqalelo ngokubanzi. I-biodegrades kwaye ayibangeli ungcoliseko olukhulu kwindalo esingqongileyo.

5. Izicelo ngaphandle kwe-putty:

Ishishini lokwakha: Ukongeza kwi-ITTYE, i-HPMC isetyenziswa ngokubanzi kwizixhobo ezahlukeneyo zokwakha, kubandakanya ukufa, imifuno kunye ne-tiles kunye ne-tiles, ukunceda ukuphucula ukusebenza, ukugcinwa kwamanzi kunye nokuqina kwamanzi kunye nokuqina kwamanzi kunye nokuqina kwamanzi.

Amayeza: I-HPMC isetyenziswa njenge-binder, i-istiongranti kunye ne-arhente yefilimu kwifom yokutsalwa kwe-sumarmaceutication ngenxa yobume bayo bokucoca kunye nepropathi elawulwa.

Umzi-mveliso wokutya: kwishishini lokutya, i-HPMC isetyenziswa njenge-thickener, i-stabilizer kunye ne-emulsifier kwiimveliso ezinjengeesosi, iidesser kunye nempahla ebhakiweyo.

6. ISIQINISEKISO:

I-Hydroxypropyl Methylcelcelgalose yi-polymer eguquguqukayo edlala indima ephambili kwifom yokubeka. Iipropathi zayo ezizodwa, kubandakanya ukubenzela amanzi, ukugcwala kwe-thermal kunye neempawu zokwenza ifilimu, nceda ukuphucula ukusebenza, ukunamathela kunye nokuqina kwe-ifakeli. Njengecandelo eliphambili lezinto zokwakha, i-HPMC iyaqhubeka nokufumana izicelo ezingaphaya kwamashishini ezahlukeneyo, zibonisa ukubaluleka kokufezekileyo kunye nokubaluleke kakhulu kwiindlela zokwakha nezakhiweyo zokwakha. Uphando oluqhubekayo kunye nophuhliso kwicandelo lezenzululwazi le-polymer linokukhokelela kwimilo yolwazi eya kwandisa uluhlu lwezinto ezizayo ze-hydropylcelose.
