I-HPC

I-HPC Hydroxypropyl Cellulose

? I-non-ionic hydroxyalkyl cellulose ether etholwe ku-cellulose ngokusebenzisa i-alkalization, i-etherification, i-neutralization, kanye nokugeza.

? Ihlukaniswe yaba i-low substituted (L-HPC) ne-high substituted (H-HPC) i-hydroxypropyl cellulose ether.

? I-L-HPC isetshenziswa kakhulu njenge-tablet disintegrator kanye ne-binder.

? I-H-HPC isetshenziswa njengesibophezelo sezemithi, izinto zokumboza ifilimu, i-ejenti yokuqina ye-elixir, njll.

Xhumana nathi

imininingwane yomkhiqizo

isingeniso somkhiqizo

I-Hydroxypropyl Cellulose (i-Hydroxypropyl cellulose) iyi-ether ye-cellulose engeyona i-ionic ebonakala njengempushana emhlophe noma emhlophe.

izici zomkhiqizo

Ukuncibilika kwamanzi okuhle kakhulu: kungancibilika ngokushesha emanzini abandayo ukuze kwakheke isixazululo esisobala nesizinzile.

Ukuzinza okuhle kokushisa: isengagcina ukusebenza kwayo okuzinzile emazingeni okushisa aphezulu.

Umsebenzi ongaphezulu: Unomsebenzi othile ongaphezulu, ungathuthukisa ukusebenza kwesixhumi esibonakalayo.

Ukubunjwa okuhle kwefilimu: Ifilimu eyakhiwe iqinile, isobala futhi inomoya omuhle wokungena.

Ukuhambisana okubanzi: kuyahambisana nezinhlobonhlobo zezinhlanganisela ze-organic kanye ne-inorganic.

ukusetshenziswa komkhiqizo

Imboni yezemithi: Njengento yokunamathisela nefilimu yokunameka amaphilisi, ingasetshenziswa futhi ukwenza amalungiselelo akhipha kancane.

Isibonelo, kwamanye amaphilisi akhishwa okuqhubekayo, isivinini sokukhululwa somuthi silawulwa ukuze kuthuthukiswe ukusebenza kahle.

Izimonyo: Isetshenziswa ku-lotions, okhilimu neminye imikhiqizo ukwandisa ukungaguquguquki nokuzinza.

Imboni yokudla: njenge-ejenti yokuqina, i-emulsifier kanye ne-stabilizer, ithuthukisa ukuthungwa nokunambitha kokudla.

Njengaku-ayisikhilimu, ukwenza kube bucayi futhi bushelelezi.

Izinto zokwakha: zingathuthukisa ukunamathela nokusebenza kokwakhiwa kodaka, i-putty, njll.

Inqubo yokukhiqiza

Ngokuvamile kwenziwa nge-cellulose ne-propylene oxide ngokufaka i-etherification ngaphansi kwezimo ze-alkali.

Amathemba emakethe

Ngokukhula kwesidingo sezinto ezingavuthiwe ezisezingeni eliphakeme ezimbonini ezahlukahlukene, iHydroxypropyl Cellulose inemakethe ethembisayo. Iqhutshwa izindinganiso eziqinile emkhakheni wezokwelapha kanye nentuthuko emisha ezimbonini zezimonyo nezokudla, isidingo sayo semakethe siyaqhubeka nokukhula.

sebenzisa izinyathelo zokuphepha

Isitoreji kufanele sibekwe endaweni eyomile, enomoya omuhle, gwema umswakama kanye nokushisa okuphezulu.

Lapho ichitheka, kufanele yengezwe kancane kancane futhi inyakaze ukuze kuqinisekiswe ukuhlakazeka okuphelele futhi kugweme ukuhlangana.

Ngokuya ngezimo ezihlukene zohlelo lokusebenza nokwakheka, ukulungiswa okunengqondo kwenani elingeziwe ukuze kuzuzwe umphumela ongcono kakhulu.

Ngamafuphi, i-Hydroxypropyl Cellulose idlala indima ebalulekile emikhakheni eminingi ngenxa yezakhiwo zayo ezinhle kakhulu, ihlinzeka ngokusekelwa okuqinile kokuthuthukiswa kwekhwalithi nokusebenza kahle kwemikhiqizo ehlobene.
