1. Isingeniso ku-hydroxypropyl methylcellulose
I-Hydroxypropyl methylcellulose (HPMC)iyi-non-ionic cellulose ether esetshenziswa kabanzi ekwakheni, kwezokwelapha, ekudleni, ezimonyweni nakwezinye izinkambu zezimboni. Inezakhiwo ezinhle zokuqina, ukwakha ifilimu, ukugcina amanzi, ukubopha, ukugcoba kanye nokuxuba, futhi ingancibilika emanzini ukuze yakhe isixazululo se-colloidal esibonakalayo noma esikhanyayo.
2. Ukusetshenziswa okuyinhloko kwe-hydroxypropyl methylcellulose
Imboni yokwakha
Udaka lukasimende: olusetshenziselwa ukuthuthukisa ukusebenza kokwakhiwa, ukuthuthukisa ukugcinwa kwamanzi nokunamathela, ukuvimbela ukuqhekeka, nokuthuthukisa amandla.
Impuphu ye-putty kanye ne-coating: kuthuthukisa ukusebenza kokwakhiwa, kuthuthukisa ukugcinwa kwamanzi, kuvimbela ukuqhekeka kanye nokuqhekeka.
I-adhesive yethayela: ithuthukisa amandla okubopha, ukugcinwa kwamanzi kanye nokulula kokwakhiwa.
Udaka oluzilinganisayo: luthuthukisa ukugeleza kwamanzi, luvimbele ukuhlukana futhi luthuthukise amandla.
Imikhiqizo ye-Gypsum: ithuthukisa ukusebenza kokucubungula, ithuthukisa ukunamathela kanye namandla.
Imboni yezemithi
Njenge-excipient yemithi, ingasetshenziswa njenge-thickener, stabilizer, emulsifier, i-film former kanye ne-ejenti yokukhulula okuqhubekayo.
Kusetshenziswa njengento eqhekekayo, enamathelayo kanye neyokumboza ekukhiqizweni kwamathebulethi.
Ihambisana kahle nezinto eziphilayo futhi isetshenziswa kabanzi ekulungiseleleni amehlo, ama-capsule kanye nokulungiselela ukukhululwa okuqhubekayo.
Imboni yokudla
Njengesengezo sokudla, sisetshenziswa kakhulu njengesithambisi, i-emulsifier, i-stabilizer kanye ne-ejenti yokwakha ifilimu.
Ifaneleka kumajamu, iziphuzo, i-ayisikhilimu, izinto ezibhakiwe, njll., ukuze iqine futhi ithuthukise ukunambitheka.
Izimonyo nemikhiqizo yokunakekela umuntu siqu
Isetshenziswa njengesithako sokujiya kanye ne-emulsifier, evame ukusetshenziswa emikhiqizweni yokunakekelwa kwesikhumba, i-shampoo, i-toothpaste, njll.
Inezakhiwo ezinhle zokuthambisa nokuqinisa, okuthuthukisa ulwazi lokusetshenziswa komkhiqizo.
Ezinye izindlela zokusebenzisa ezimbonini
Isetshenziswa njengesithambisi, isinamathelisi noma i-emulsifier ezintweni zobumba, izindwangu, ukwenza amaphepha, uyinki, izibulala-zinambuzane kanye neminye imboni.
3. Indlela yokusebenzisa
Indlela yokuncibilikisa
Indlela yokusabalala kwamanzi abandayo: Fafaza kancane i-HPMC emanzini abandayo, uvuselele njalo kuze kuhlakazeke ngokulinganayo, bese ufudumala kufike ku-30-60℃ bese uncibilika ngokuphelele.
Indlela yokuncibilikisa amanzi ashisayo: qala ngokumanzisa i-HPMC ngamanzi ashisayo (ngaphezu kuka-60°C) ukuze ivuvuke, bese ufaka amanzi abandayo bese uvuselela ukuze incibilike.
Indlela yokuxuba okomile: qala uhlanganise i-HPMC nezinye izimpushana ezomile, bese ufaka amanzi bese uvuselela ukuze uyincibilikise.
Inani lokwengeza
Embonini yokwakha, inani elengeziwe le-HPMC ngokuvamile lingu-0.1%-0.5%.
Ezimbonini zokudla nezokwelapha, inani lokwengeza lilungiswa ngokwenhloso ethile.
4. Izinyathelo zokuqapha zokusetshenziswa
Izimo zokugcina
Gcina endaweni epholile, eyomile, enomoya omuhle, gwema umswakama kanye nokukhanya kwelanga okuqondile.
Gcina kude nemithombo yokushisa, imithombo yomlilo kanye nama-oxidant aqinile ukuze uvimbele ukubola nokusha.
Izinyathelo Zokuqapha Zokuhlakazeka
Gwema ukufaka inani elikhulu le-HPMC ngesikhathi esisodwa ukuze uvimbele ukwakheka kwamaqhubu futhi kuthinte umphumela wokuncibilika.
Ijubane lokuncibilika lihamba kancane endaweni enezinga lokushisa eliphansi, futhi izinga lokushisa lingakhushulwa ngokufanele noma isikhathi sokuxuba singandiswa.
Ukuphepha kokusetshenziswa
I-HPMC iyisithako esingenabo ubuthi futhi esingenangozi, kodwa ingabangela ukucasuka kokuphefumula esimweni sempuphu, futhi uthuli oluningi kufanele lugwenywe.
Kunconywa ukugqoka imaski nezibuko ngesikhathi sokwakha ukuze ugweme ukucasuka kothuli endleleni yokuphefumula namehlo.
Ukuhambisana
Uma usebenzisa, qaphela ukuhambisana namanye amakhemikhali, ikakhulukazi lapho ulungiselela izinto zokwakha noma izidakamizwa, kudingeka ukuhlolwa kokuhambisana.
Emkhakheni wokudla nemithi, kumele kuhlangatshezwane nemithethonqubo nezindinganiso ezifanele ukuqinisekisa ukuphepha.
I-Hydroxypropyl methylcelluloseisetshenziswa kabanzi ezimbonini eziningi ngenxa yokusebenza kwayo okuhle kakhulu. Ngesikhathi sokusetshenziswa, kubalulekile ukwazi indlela efanele yokuncibilikisa kanye namakhono okusebenzisa, futhi unake izindaba zokugcina nokuphepha ukuqinisekisa ukuzinza nokusebenza komkhiqizo. Ukusetshenziswa okufanele kwe-HPMC akugcini nje ngokuthuthukisa ikhwalithi yomkhiqizo, kodwa futhi kuthuthukisa ukusebenza kahle kokwakhiwa nokukhiqiza.
