Yiziphi izici ze-hydroxypropyll methylcellulose (HPMC)?

I-Hydroxypropyl methylcellulose (HPMC)yi-ether ye-anulic cellulose enobubanzi bezicelo. Okulandelayo izici eziphambili ze-HPMC:

1. Izakhiwo zamakhemikhali
I-HPMC iyi-ether ye-annoinic cellulose ether ecwengekile ezintweni zemvelo ze-polymer ngokusebenzisa i-alkalization kanye nokusabela kokuthezeka. Ihlanganiswe ikakhulukazi nge-methoxy (-Och₃) neHydroxypropoxy (-Och₂choHch₃) Amaqembu angenamikhawulo e-Hydroxyl. Izinga lokufaka esikhundleni linquma i-solubity yalo, lokushisa le-gelation, i-viscosity kanye nezinye izici.

2. I-solubility yamanzi kanye ne-gelation eshisayo
I-HPMC iyancibilika emanzini abandayo ukwakha isixazululo esibonakalayo noma esibonakalayo, kepha ama-gels emanzini ashisayo. Njengoba izinga lokushisa likhuphuka, ikhambi le-Kimacell®HPMC elinamanzi kancane kancane lilahlekelwa ukubonakala futhi lakha ijeli. Le mpahla isetshenziswa kabanzi emikhakheni yokwakha, umuthi nokudla. Isibonelo, ezintweni zokwakha, i-HPMC ingathuthukisa ukugcinwa kwamanzi ngodaka, ngenkathi embonini yokudla ingasetshenziswa njengomuntu omkhulu ne-stabilizer.

3. Ukuqina kwempahla
Isixazululo se-HPMC sinempahla enhle kakhulu yokuqina futhi singanikeza i-viscosity ephezulu ekuhlushwa okuphansi. Kusetshenziswa kabanzi ku-coatings, glues, kwakha odongeni kanye nezinye izinkambu. I-viscosity ye-HPMC incike ngezinga layo le-polymerization kanye nokufakwa esikhundleni. Abasebenzisi bangakhetha imikhiqizo ene-viscosities ehlukile ngokuya ngezidingo zabo.

4. Ukugcinwa kwamanzi
Indima ebalulekile ye-HPMC embonini yezokwakha ukuthuthukisa ukugcinwa kwamanzi kwezinto zodaka zodaka ngosimende kanye nezinto zokwakha ama-gypsum, ukunciphisa ukulahleka kwamanzi ngesikhathi sokwakha, kanye nokwenza ngcono ukusebenza kokwakha namandla okugcina. Embonini we-Coating, i-HPMC isiza ukuvikela ukuthambeka kwe-pigment futhi kuthuthukise ukufana.

5. Impahla ekwakheka ifilimu
I-HPMC ingakha ifilimu esobala futhi eguquguqukayo ebusweni. Le mpahla yenza kubalulekile ekuhlanganiseni imithi yezemithi, ukuhlanganiswa kokudla, imboni ye-ceramic kanye nezinye izinkambu. Kungathuthukisa ukuqina kwamathebulethi, kuvikele izidakamizwa ukuthi zingangeni, futhi zinikeze ukunambitheka okuhle.

6. Ukugcona kanye Rheology
I-HPMC ingathuthukisa izakhiwo ze-mbosongo ngodaka, izimbobo nakwezinye izinhlelo zokusebenza, okwenza izinto zibe lula ukuzakha. Isibonelo, kuma-tile anamathela, i-hpmc ingathuthukisa ama-lothlity, inciphise ukumelana nokusebenza kokusebenza nokwenza ngcono ukusebenza kokwakha.

7. Ukuqina kwe-PH
I-HPMC ihlala iqinile kuhlu lwe-PH lwe-3-11 futhi ingathintekiswa kalula nge-acid ne-alkali, ngakho-ke ingasetshenziswa ezindaweni ezihlukile. Kodwa-ke, ukubonakala kwayo kungashintsha noma ukungcolisa ngaphansi kwezimo ezinamandla ze-acid noma i-alkali.

8. Umsebenzi we-Race
I-HPMC inomsebenzi othile ongaphezulu komhlaba futhi ingasetshenziselwa ukufakwa emulsation, ukuhlakazeka kanye nokuzinza kwezinhlelo zokumiswa. Kusetshenziswa kabanzi e-Latex Coatings, izimonyo kanye nezimboni zokudla.

9. Ukuqina nokuphepha
I-HPMC ine-biocomtic enhle kanye nobuthi obuphansi, ngakho-ke isetshenziswa kabanzi kwezokwelapha, ukudla kanye nezimonyo. Isibonelo, emalungiseleleni amakhamithi, i-HPMC ingasetshenziswa njenge-tablet yethebhulethi, i-ejenti yokukhishwa okuqhubekayo, i-ejenti ye-coating, njll.

10. Ukumelana nosawoti
I-KimaCell®HPMC inokubekezelelana okuhle kosawoti ojwayelekile (njenge-sodium chloride, i-sodium sulfate, njll.), Futhi akwenziswa kalula noma kufakwe kalula kutholwa ama-electrolytes, okuvumela ukuthi kusetshenziswe amasistimu aqukethe usawoti.

Izindawo zohlelo lokusebenza
Izinto zokwakha: ezisetshenziswe ku-cunmer data, imikhiqizo ye-gypsum, i-tile anamathela, i-putty powder, ukuthuthukisa ukusebenza kokwakha nokugcinwa kwamanzi.
Imboni yezemithi: Njengomuthi i-pusticant, esetshenziswa kuma-tablet coating, i-ejenti yokukhishwa okuqhubekayo, i-gel, njll.
Imboni yokudla: Njengomkhulu, i-emulsifier, i-stabilizer, esetshenziswe emikhiqizweni yobisi, ukubhaka, jelly, njll.
Imidwebo nopende: Thuthukisa i-Rheology, ukuqina, ukuqina kokumiswa, nokwenza ngcono ukusebenza kokwakha.
Imikhiqizo yamakhemikhali yansuku zonke: isetshenziswa eShampoo, imikhiqizo yokunakekelwa kwesikhumba, amazinyo, njll., Ukuhlinzeka ngokuqina nokuzinza.
I-HPMCUdlala indima ebalulekile ezimbonini eziningi ngenxa ye-solubility yayo enhle kakhulu, ukuqina, ukugcinwa kwamanzi kanye nokuqina.
