I-Viscosity Modifier: I-HPMC isetyenziselwa ukulungisa i-viscosity yamaconsi eliso ukuze inike ukuthambisa okufanelekileyo nokuqinisekisa ixesha elide lokudibana nomphezulu weliso.
Izinto zokufakela iifilimu: ezisetyenziselwa ukuvelisa iimaski zamehlo okanye izinto zokufaka amayeza ukuze kukhutshwe amayeza rhoqo emehlweni.
C. Ukulungiselela izinto ezisetyenziswa apha emzimbeni:
Ukwenziwa kwejeli: I-HPMC isetyenziselwa ukulungiselela iijeli ezisetyenziswa ngelaphu ezibonelela ngoburhabaxa obuthambileyo, obungenamafutha kwaye buphucula ukuthotyelwa kwemigaqo yesigulana.
Izincamathelisi zesikhumba: Kwiinkqubo zokuhambisa amayeza e-transdermal, i-HPMC inika iimpawu zokuncamathelisa kwaye ilawula ukukhutshwa kwamayeza eluswini.
D. Izinto Ezifakwayo Ezibolayo:
Izinto ezisetyenziswa kwi-scaffold: I-HPMC isetyenziselwa ukwenza izinto ezifakwa kwi-biobolid implants ezilawula ukukhutshwa kwamayeza emzimbeni, nto leyo esusa isidingo sokususwa ngotyando.
2. Ishishini lokwakha
A. Isincamathelisi sethayile:
Isiqinisi: I-HPMC isetyenziswa njengesiqinisi kwizincamathelisi zethayile ukuze inike ulungelelwano olufunekayo ukuze kube lula ukuyisebenzisa.
Ukugcinwa Kwamanzi: Iphucula ukugcinwa kwamanzi kwesincamathelisi, ithintela ukuba singami ngokukhawuleza kwaye iqinisekise ukuba sinyangeka ngokufanelekileyo.
B. Udaka lwesamente:
Ukusebenza kakuhle: I-HPMC isebenza njengohlengahlengiso lwe-rheology ukuthintela ukwahlulwahlulwa kunye nokuphucula ukubopha, ngaloo ndlela iphucula ukusebenza kakuhle kweemortars ezisekwe kwisamente.
Ukugcinwa Kwamanzi: Njengento yokuncamathelisa iithayile, inceda ukugcina umswakama kumxube ofaka isamente, nto leyo evumela ukuba kubekho ukufuma okufanelekileyo kunye nokukhula kwamandla.
3. imboni yokutya
A. Izongezo zokutya:
Izinto zokuThibilikisa kunye neziQinisekisa: I-HPMC isetyenziswa njengesiqinisi kunye nesiqinisi kwiintlobo ngeentlobo zeemveliso zokutya, ezinje ngeesosi, iidizethi kunye needizethi.
Ukutshintsha amafutha: Kwizinto zokutya ezinamafutha aphantsi okanye ezingenamafutha, i-HPMC ingasetyenziswa njengento yokutshintsha amafutha ukuphucula ukuthungwa kunye nokuvakala komlomo.
4. Ishishini lezinto zokuthambisa
A. Iimveliso zokhathalelo lomntu:
Ulawulo lweViscosity: I-HPMC isetyenziswa kwiindlela zokuhombisa ezifana neeloshini kunye neekhrimu ukulawula i-viscosity kunye nokuphucula ubume bendalo iyonke.
Izinto ezivelisa iifilimu: Nceda wenze ifilimu kwiimveliso zokhathalelo lweenwele, nto leyo enika umaleko okhuselayo.
5. Ezinye izicelo
A. I-inki yokuprinta:
Isiqinisi: I-HPMC isetyenziswa njengesiqinisi kwii-inki zokuprinta ezisekelwe emanzini ukunceda ekufezekiseni ukuhambelana okufunekayo kunye nokuzinza kwe-inki.
B. Iimveliso ezincamathelayo:
Phucula i-viscosity: Kwiifomyula zokuncamathelisa, i-HPMC ingongezwa ukuphucula i-viscosity kunye nokuphucula iimpawu zokubopha.
5. ekugqibeleni
Ukusetyenziswa kwe-HPMC kwiimveliso ezahlukeneyo kubonisa ukuguquguquka kwayo kunye nokusebenza kwayo. Ukusetyenziswa kwayo kumayeza, ulwakhiwo, ukutya, izinto zokuthambisa kunye nezinye iinkalo kubonisa indibaniselwano yayo eyahlukileyo yeempawu, kubandakanya amandla okwenza ifilimu, iimpawu zokutyeba kunye nozinzo. Njengoko ubuchwepheshe kunye nophando luhambela phambili, i-HPMC isenokuqhubeka nokudlala indima ebalulekileyo kuphuhliso lweemveliso ezintsha kunye neefomyula kumacandelo ahlukeneyo.
