I-HPMC noma i-hydroxypropyl methylcellulose iyinhlanganisela evame ukusetshenziswa ezimbonini ezihlukahlukene ezihlanganisa ezemithi, izimonyo nezokwakha.Nayi eminye imibuzo evame ukubuzwa mayelana ne-HPMC:
Iyini i-hypromellose?
I-HPMC iyi-polymer yokwenziwa eyenziwe nge-cellulose, into engokwemvelo etholakala ezitshalweni.Yenziwe ngokushintsha amakhemikhali i-cellulose ngamaqembu e-methyl kanye ne-hydroxypropyl ukuze kwakhiwe impushana encibilika emanzini.
Isetshenziselwa ini i-HPMC?
I-HPMC inokusetshenziswa okuningi ezimbonini ezahlukene.Embonini yezemithi, isetshenziswa njenge-binder, thickener kanye ne-emulsifier yamaphilisi, amaphilisi namafutha okugcoba.Embonini yezimonyo, isetshenziswa njenge-thickener, emulsifier kanye ne-stabilizer kumakhilimu, ama-lotions kanye nokwenza-up.Embonini yezokwakha, isetshenziswa njenge-binder, i-thickener kanye ne-ejenti yokugcina amanzi kusimende nodaka.
Ingabe ama-HPMC aphephile?
I-HPMC ngokuvamile ibhekwa njengephephile futhi engeyona into enobuthi.Isetshenziswa kakhulu ezimbonini zemithi nezimonyo lapho ukuphepha nokuhlanzeka kubaluleke kakhulu.Nokho, njenganoma iyiphi ikhemikhali, kubalulekile ukuphatha i-HPMC ngokucophelela futhi ulandele izinyathelo zokuphepha ezifanele.
Ingabe i-HPMC iyabola?
I-HPMC iyakwazi ukubola futhi ingahlukaniswa ngezinqubo zemvelo ngokuhamba kwesikhathi.Kodwa-ke, izinga lokubola kwezinto eziphilayo lincike ezintweni ezihlukahlukene ezifana nezinga lokushisa, umswakama kanye nokuba khona kwama-microorganisms.
Ingabe i-HPMC ingasetshenziswa ekudleni?
I-HPMC ayigunyaziwe ukuthi isetshenziswe ekudleni kwamanye amazwe, kuhlanganise ne-United States.Kodwa-ke, kuvunyelwe njengesengezo sokudla kwamanye amazwe anjengeJapan neChina.Isetshenziswa njenge-thickener ne-stabilizer kokunye ukudla, okufana no-ayisikhilimu nezinto ezibhakwayo.
Yenziwa kanjani i-HPMC?
I-HPMC yenziwa nge-cellulose eshintsha amakhemikhali, into engokwemvelo etholakala ezitshalweni.I-Cellulose iqala ukuphathwa ngesisombululo se-alkaline ukuze isuse ukungcola futhi iyenze isebenze kakhulu.Ibe-ke isabela ngengxube ye-methyl chloride ne-propylene oxide ukwenza i-HPMC.
Ayini amabanga ahlukene e-HPMC?
Kunamabanga amaningana e-HPMC, ngalinye linezakhiwo nezakhiwo ezihlukile.Amabanga asekelwe ezintweni ezifana nesisindo samangqamuzana, izinga lokushintshwa, kanye nezinga lokushisa le-gelation.Amabanga ahlukene e-HPMC asetshenziswa ezinhlelweni ezahlukene ezimbonini ezahlukene.
Ingabe i-HPMC ingaxutshwa namanye amakhemikhali?
I-HPMC ingaxutshwa namanye amakhemikhali ukuze kukhiqizwe izakhiwo nezici ezahlukene.Ivamise ukuhlanganiswa namanye ama-polymers njenge-polyvinylpyrrolidone (PVP) ne-polyethylene glycol (PEG) ukuze kuthuthukiswe izici zayo zokubopha nokujiya.
Igcinwa kanjani i-HPMC?
I-HPMC kufanele igcinwe endaweni epholile, eyomile ekude nomswakama kanye nokukhanya kwelanga okuqondile.Kufanele igcinwe esitsheni esingangenisi umoya ukuze kuvinjelwe ukungcoliswa.
Yiziphi izinzuzo zokusebenzisa i-HPMC?
Izinzuzo zokusebenzisa i-HPMC zihlanganisa ukuguquguquka kwayo, ukuncibilika kwamanzi, kanye nokubola kwemvelo.Futhi ayinabo ubuthi, izinzile, futhi iyahambisana namanye amakhemikhali amaningi.Ngokushintsha izinga lokushintshwa kanye nesisindo samangqamuzana, izakhiwo zayo zingashintshwa kalula, zenze zifaneleke ezihlukahlukene zezicelo.
