Hydroxypropyl methylcelculose (hpmc)Ngaba i-selsulose esetyenziswa ngamanzi asetyenziselwa amanzi amaninzi, isetyenziswa ngokubanzi ekwakhiweni, amayeza, ukutya kunye nemizi mveliso yemichiza yemihla ngemihla. Kwizinto zokwakha, ngakumbi kwiindawo zeTile, i-fallties yodonga, i-HPM.
1. Iipropathi ezisisiseko ze-HPMC
I-Nuinccel®HPMM yi-selsulose ikhutshiwe ngokulinganayo kwamanzi, i-adhesion kunye neziphumo zokonwaba. Yenza i-colloid emanzini nge-hydroxypropy ye-hydroxyl kunye namaqela e-methyl kwisakhiwo sayo semolekyuli, enokuthi iphucule ngokufanelekileyo ukunamathela, i-gemology kunye nokugcinwa kwamanzi. Ekwakheni imihlambi, ukongezwa kwe-HPMC kunokuphucula amandla amakhulu, ukwandisa ixesha elivulekileyo, kunye nokuphucula ukusasazeka kunye nokuxhathisa kwamanzi. Ke ngoko, isixa se-HPMC sihambelana ngqo nokusebenza kwezi propati, ezichaphazela isiphumo se-bill.
2. Isiphumo se-HPMC Dosage kumandla e-bondile
Amandla oKhuphoso sisikhombisi esiphambili sokuvavanya isiphumo sokwakha amachaphaza. Isixa se-HPMC esongezwe kwi-Adhesive sinokuchaphazela kakhulu amandla aphezulu. Kwelinye icala, isixa esifanelekileyo se-HPMC sinokuphucula ukugoba kunye namandla esamente esekwe. Kungenxa yokuba i-HPMC iphucula udaka lwamanzi, ivumela isamente ukuba iphinde yenze ngcono i-shemically kunye nomphezulu wenkqubo yokuqalisa, ngaloo ndlela kuphuculwe isiphumo sokugqibela. Kwelinye icala, xa isixa se-HPMC sincinci kakhulu, ukugcinwa kwamanzi kwawo akonelanga, okunokubangela isamente ukuba iphulukane namanzi ngaphambi kwexesha, ichaphazela amandla okwenza izinto; Ngelixa imali inkulu kakhulu, inokubangela ukuba ukunamathela ukubambelela kakhulu, kuchaphazele umsebenzi wokwakha kwaye nokubangela ukuncipha kwamandla.
Izifundo zibonise ukuba ezona mali zifanelekileyo ze-HPMC zihlala ziphakathi kwe-0.5% ne-2%, enokuthi iphucule ngokufanelekileyo amandla aphezulu kolu luhlu olufana nolwenzi kunye nokusebenza. Nangona kunjalo, isixa esithile kufuneka silungiswe ngokohlobo lomgangatho kunye nendawo ethile yesicelo.
I-3. Isiphumo se-HPMC Dosage kwintsebenzo yokwakha
Umsebenzi wokwakha yenye yeempawu ezibalulekileyo zokuvavanya abanamathemane, ubukhulu becala kubandakanya ulwalamano, ngokulula kwexesha lokwakha nehlengahlengiselweyo. Isixa se-HPMC sinefuthe elibonakalayo kwezi ndawo. Njengamanani onyuswe i-HPMC, i-viscomosity ye-adhesive nayo inyuka, ibonisa ububi obuqinileyo kwaye ixesha elide elivulekileyo. Nangona ixesha elivulekileyo elivulekileyo linokuthi ngamanye amaxesha linokuphucula ukuguquguquka kokwakhiwa, kunokubangela ukuba indawo yokwakha ibuye ichaphazele kwaye ichaphazele isiphumo sokwabiwa.
Ngeentlobo ezahlukeneyo zendawo eziphantsi, ezinjengeethayile, amatye, iindonga, njl.njl. Umzekelo, kwiimeko apho ixesha elide lokutya kunye nohlengahlengiso luyafuneka, ukwandisa isixa se-HPMC ngokufanelekileyo sinokwandisa ixesha elivulekileyo kunye nokuphepha ukomisa ngokukhawuleza, kukhokelela kubuthathaka buthathaka. Nangona kunjalo, ukuba ixesha elivulekileyo lide kakhulu, linokubangela ukuntywila ngokungeyomfuneko ngexesha lokwakha kwaye kuchaphazele ukuchaneka kokwakha.
I-4. Isiphumo se-HPMC Dossage ekuchanyoneni kwamanzi kunye nokuxhathisa kwemozulu
I-HPMC ayinakuphucula kuphela ukomelela kunye nokusebenza ngokwakhiwa, kodwa kukuphucula ukumelana kwamanzi kunye nokuchasana kwemozulu. I-HPMC iphucula ukugcinwa kwamanzi kwesamente, ukuze isamente esekwe kwisamente asiyi kuphulukana namanzi ngokukhawuleza ngexesha lenkqubo enzima, ngaloo ndlela kuphuculwe ukumelana namanzi kunye nokuchasana nemozulu. Xa idosi ye-HPMC ifanelekile, ukumelana kwamanzi kunye nobomi benkonzo yezixhobo kunokuphuculwe kakhulu, ngakumbi kwiindonga zangaphandle kunye neendawo ezinomswakama, apho amanzi okubulala amanzi abalulekile.
Nangona kunjalo, i-HPMC egqithisileyo ingakhokelela ekutsaleni okugqithisileyo kokunamathela kakhulu, kuchaphazela uzinzo lwezakhiwo zesamente, kwaye zinciphise ukumelana kwamanzi. Ke ngoko, ukwenza i-DPMC ye-HPMC ukulungelelanisa i-hydration kunye nokuchasana kwamanzi kwesamente yeyona nto iphambili ekuqinisekiseni isiphumo sokuqina.
I-5. Iziphumo ze-HPMC Dosage kwezinye iipropathi zomzimba
Ukongeza kumandla okuxhuzula, ukusebenza kwamanzi, ukuxhathisa kwamanzi, njl njl, i-HPMC iya kuchaphazela nezinye iimpawu zomzimba zokuthambeka. Umzekelo, ukonyuka kwedosi ye-HPMC, uzinzo lonongatho lunokuphuculwa kuba i-HPMC ingathintela i-sediment kunye nokuxhuzulwa kukhenketho kunye nokugcina ubumbeko. Ukongeza, idosi yeI-HPMCInxulumene ngokusondeleyo nezinto ezifana nombala, iipropathi ezichasene nezilayidi, kunye nexesha lokunyanga. Imicimbi eyahlukeneyo ye-HPMC inokufikelela kwintsebenzo ebonakalayo emzimbeni phantsi kweemfuno ezahlukeneyo zokwakha.
Njengesongezelelo esibalulekileyo sokwakha izibhengezo, iAnsinccel®hpmc inefuthe elibonakalayo kwifuthe lokuxhoma. Umthamo wayo kufuneka uqinisekiswe ngokweemfuno ezithile zokwakha, iimpawu zenqanaba kunye neemeko zokusingqongileyo. Isixa esifanelekileyo se-HPMC sinokuphucula amandla okusebenza, ukusebenza kwamanzi, ukuxhathisa kwamanzi kunye nokungathinteli kwemozulu, ngelixa kugcinwa uzinzo oluhle lomzimba. Nangona kunjalo, i-HPMC egqithisileyo okanye i-HPMC inokukhokelela kwiipropathi ezingazinzanga kwaye ichaphazele iziphumo. Ke ngoko, kwizicelo ezenziwayo, kuyimfuneko ukufumanisa umthamo we-HPMC ofanelekileyo ngovavanyo kunye nohlengahlengiso ukufezekisa isiphumo esifanelekileyo se-bill.
