1. Iyini i-hydroxypropyll methylcellulose?
I-Hydroxypropyl methylcellulose (HPMC)Ingabe i-ether ye-cellulose engenabungozi futhi engenangozi futhi engenangozi, esetshenziswa kabanzi kwezinto zokwakha, ukudla, umuthi, izimonyo kanye nezinye izinkambu. Inemisebenzi yokuqina, ukugcinwa kwamanzi, ukwakheka kwamafilimu, ukubopha izibopho, ukuthambisa kanye nokumiswa kwamanzi, futhi kungancibilikisa ngesisombululo se-viscous noma esibonakalayo.
2. Ukusetshenziswa okujwayelekile nokusetshenziswa kwe-HPMC
Inkambu yokwakha
I-HPMC isetshenziswa kakhulu ezintweni zokwakha ezifana nosimende kasimende, i-putty powder, i-tile anamathela, njll.
Umsebenzi: Thuthukisa ukusebenza kokwakhiwa, uthuthukise ukugcinwa kwamanzi, unwebe isikhathi esivulekile, futhi uthuthukise ukusebenza kwe-Bonding.
Indlela yokusebenzisa:
Engeza ngqo ku-wonduka omile oxutshwe, inani elinconyiwe lingu-0,1% ~ 0.5% wesisindo sikasimende noma i-substrate;
Ngemuva kokuvusa ngokugcwele, engeza amanzi bese uvuse ube slurry.
Imboni yokudla
I-HPMC ingasetshenziswa njengesikhulu, i-stabilizer kanye ne-emulsifier, futhi ivame ukutholakala ekudleni okufana no-ayisikhilimu, i-jelly, isinkwa, njll.: Njll.
Umsebenzi: Thuthukisa ukunambitha, qinisa inqubo, futhi uvikele ukuhlukaniswa.
Ukusetshenziswa:
Chaza emanzi abandayo, umthamo onconyiwe uguqulwe phakathi kuka-0.2% no-2% ngohlobo lokudla;
Ukushisa noma ukushukumisa imishini kungasheshisa ukuqedwa.
Imboni yezemithi
I-HPMC ivame ukusetshenziselwa ukuhlanganiswa kwezidakamizwa, i-matrix yokukhipha ithebhulethi eqhubekayo noma igobolondo le-capsule:
Umsebenzi: Ukwakheka kwamafilimu, ukukhishwa kwezidakamizwa okubambezeleka, nokuvikelwa komsebenzi wezidakamizwa.
Ukusetshenziswa:
Lungiselela isisombululo ngenhlanganisela ye-1% kuya ku-5%;
Fafaza ngokulinganayo ebusweni bethebhulethi ukwakha ifilimu elincanyana.
Izimonyo
I-HPMCisetshenziswa njengesikhudlwana, i-emulsion stibilizer noma i-ejenti eyakha ifilimu, evame ukusetshenziswa kumaski ebusweni, i-lotions, njll.
Umsebenzi: Thuthukisa ukuthungwa futhi uthuthukise umuzwa womkhiqizo.
Ukusetshenziswa:
Ngeza kuMatrix wezimonyo ngokwesilinganiso futhi uvuse ngokulinganayo;
Umthamo ngokuvamile u-0,1% kuya ku-1%, alungiswe ngokuya ngezidingo zomkhiqizo.
3. Indlela yokuchithwa kwe-HPMC
I-solubity ye-HPMC ithintwe kakhulu ngokushisa kwamanzi:
Kulula ukuncibilikisa emanzini abandayo futhi kungakha isixazululo esifanayo;
Kuyinto engabonakali emanzini ashisayo, kepha ingahlakazeka futhi yakha i-colloid ngemuva kokupholisa.
Izinyathelo Ezincathuko ezithile:
Fafaza i-HPMC kancane emanzini, gwema ukuthulula ngqo ukuvikela ukukheka;
Sebenzisa i-stitterrer ukuxuba ngokulinganayo;
Lungisa ukugxila kwesixazululo njengoba kudingeka.
4. Izinyathelo zokusebenzisa i-HPMC
I-DOSAGE Control: Ezimweni ezihlukile zohlelo lokusebenza, umthamo uthinta ngqo ukusebenza futhi udinga ukuhlolwa ngokuya ngezidingo.
Izimo Zokugcina: Kufanele zigcinwe endaweni epholile, eyomile, enomoya wokugwema umswakama kanye nokushisa okuphezulu.
Ukuvikelwa Kwezemvelo: I-HPMC iyi-biodegradable futhi ayingcolisi imvelo, kepha isadinga ukusetshenziselwa ngendlela evamile ukugwema imfucuza.
Ukuhlolwa kokuvumelana: Uma kungezwe kuzinhlelo eziyinkimbinkimbi (njengezimonyo noma imithi), ukuhambisana nezinye izithako kufanele kuhlolwe.
I-5. Izinzuzo ze-HPMC
Okungewona ubuthi, enobuntu, ukuphepha okuphezulu;
Ukuguquguquka, kuyavumelana nezidingo ezahlukahlukene zezicelo;
Ukuqina okuhle, kungagcina ukusebenza isikhathi eside.
6. Izinkinga ezijwayelekile nezixazululo
Inkinga ye-Agglomeration: Nakisisa ukwengeza okuhlakazekile ngesikhathi sokusebenzisa futhi uvuse ngokugcwele ngasikhathi sinye.
Isikhathi eside sokuchithwa
Ukuwohloka kokusebenza: Naka imvelo yokugcina ukuze uvikele umswakama nokushisa.
Ngokusebenzisa i-HPMC ngokwesayensi nangokomqondo, izici zayo ezisebenzayo zingasetshenziswa ngokuphelele ukuhlinzeka ngezixazululo ezisezingeni eliphakeme zemikhakha ehlukahlukene.
