I-Hydroxypropyl methylcellulose (HPMC)iyimpahla ye-polymer esebenzayo eyingxenye yemikhiqizo ye-cellulose ether. Ngenxa yezakhiwo zayo ezinhle kakhulu zomzimba namakhemikhali, isetshenziswa kabanzi emkhakheni wokwakha, umuthi, ukudla, amakhemikhali ansuku zonke, njll.
1. Izakhiwo eziyisisekelo
IHydroxypropyl methylcellulose iyinhlanganisela ye-polymer engeyona i-ionic emanzini eyenziwe nge-cellulose yemvelo ngokuguqulwa kwamakhemikhali. Izakhiwo zayo eziyinhloko zihlanganisa:
I-solubility enhle kakhulu yamanzi: Ingancibilika emanzini abandayo ukuze yakhe isisombululo se-viscous esisobala.
Ukuqina komphumela: Kungakhuphula ngempumelelo i-viscosity yoketshezi noma ama-slurries.
Ukugcinwa kwamanzi: Kunomphumela omuhle kakhulu wokugcina amanzi, ikakhulukazi ezintweni zokwakha ukuvimbela ukoma nokuqhekeka ngokushesha.
Isakhiwo sokwenza ifilimu: Ingenza ifilimu ebushelelezi futhi eqinile endaweni enokumelana okuthile nowoyela kanye nokungena komoya.
Ukuzinza kwamakhemikhali: Iyakwazi ukumelana ne-asidi ne-alkali, imelana nokukhunta, futhi izinzile ebangeni le-pH elibanzi.
2. Izindawo zokufaka izicelo eziyinhloko
Inkambu yokwakha
I-AnxinCel®HPMC isetshenziswa kakhulu odakeni oluxutshwe okomile, i-putty powder, i-adhesive tile kanye nezingubo embonini yezokwakha.
Udaka oluxutshwe okomile: I-HPMC ithuthukisa ukusebenza, ukusebenza kokwakhiwa kanye nokugcinwa kwamanzi kodaka, okwenza kube lula ukusebenzisa, kuyilapho ivimbela ukuqhekeka noma ukulahlekelwa amandla ngemva kokoma.
I-adhesive yethayela: Ithuthukisa ukunamathela kanye nezakhiwo zokulwa nokushelela, ithuthukisa ukusebenza kahle kokwakhiwa.
I-Putty powder: Yandisa isikhathi sokwakha, yenza ngcono ukushelela kanye nokumelana nokuqhekeka.
Upende weLatex: I-HPMC ingasetshenziswa njenge-thickener kanye ne-stabilizer ukunikeza upende ukuxubha okuhle kakhulu kanye nezakhiwo zokuleveling, kuyilapho kuvimbela ukuvela kwe-pigment sedimentation.
Inkambu yezemithi
Embonini yezemithi, i-HPMC isetshenziswa kakhulu njengesamukeli sezemithi futhi isetshenziswa kakhulu kumaphilisi, amaphilisi kanye namalungiselelo okukhishwa okuqhubekayo.
Amaphilisi: I-HPMC ingasetshenziswa njenge-ejenti eyenza ifilimu ukunikeza amaphilisi ukubukeka okuhle kanye nezakhiwo zokuzivikela; ingasetshenziswa futhi njenge-adhesive, disintegrant kanye ne-stained-release-release material.
Amaphilisi: I-HPMC ingathatha indawo ye-gelatin ukuze ikhiqize amaphilisi aqinile asekelwe esitshalweni, afanele abantu abadla imifino kanye neziguli ezingezwani ne-gelatin.
Amalungiselelo okukhishwa okuqhubekayo: Ngomphumela we-gelling we-HPMC, izinga lokukhululwa lomuthi lingalawulwa ngokunembile, ngaleyo ndlela kuthuthukiswe ukusebenza kahle.
Imboni Yokudla
Embonini yokudla, i-HPMC isetshenziswa njenge-emulsifier, thickener and stabilizer, futhi ivame ukutholakala ezimpahleni ezibhakwayo, eziphuzweni naseziphuzweni.
Izimpahla ezibhakiwe: I-HPMC inikeza imiphumela yokuswakama nokubumba, ithuthukisa ukusebenza kwenhlama, futhi ithuthukisa ukunambitheka nekhwalithi yemikhiqizo eqediwe.
Iziphuzo: Khulisa i-viscosity yoketshezi, thuthukisa ukuqina kokumiswa, futhi ugweme ukuhlukaniswa.
Okuthatha indawo yemifino: Enyameni esekwe ezitshalweni noma emikhiqizweni yobisi, i-HPMC isetshenziswa njenge-thickener noma i-emulsifier stabilizer ukunikeza umkhiqizo ukunambitheka nokuthungwa okufanele.
Amakhemikhali nsuku zonke
Ekunakekelweni komuntu siqu kanye nemikhiqizo yasendlini, i-AnxinCel®HPMC isetshenziswa kakhulu njenge-thickener, emulsifier stabilizer kanye nefilimu yangaphambili.
Izihlanzi: Nikeza umkhiqizo i-viscosity emaphakathi futhi uthuthukise umuzwa wokusetshenziswa komkhiqizo.
Imikhiqizo yokunakekelwa kwesikhumba: I-HPMC ithuthukisa ukuswakama nokusabalala kumaloshini namakhilimu.
Umuthi wokuxubha: Udlala indima yokujiya nokumisa ukuze uqinisekise ukufana kwezithako zefomula.
3. Amathemba entuthuko
Ngokukhuthazwa kwemiqondo yokuvikela imvelo eluhlaza kanye nokwanda kwezindawo zokufaka izicelo, isidingo se-hydroxypropyl methylcellulose siyaqhubeka nokukhula. Embonini yezokwakha, i-HPMC, njengengxenye ebalulekile yokonga ugesi kanye nezinto ezithinta imvelo, inamathuba emakethe abanzi; emkhakheni wezokwelapha nokudla, i-HPMC isibe isithako esibalulekile ngenxa yokuphepha nokuhlukahluka kwayo; emikhiqizweni yamakhemikhali yansuku zonke, ukusebenza kwayo okuhlukahlukene kunikeza amathuba emikhiqizo emisha.
I-Hydroxypropyl methylcelluloseisibe yinto ebalulekile yamakhemikhali ezimbonini eziningi ngenxa yezakhiwo zayo ezinhle kakhulu kanye nokusetshenziswa okubanzi. Ngokuzayo, ngokuthuthukiswa okwengeziwe kwezinqubo zokukhiqiza kanye nokuvela okuqhubekayo kwezidingo ezintsha, i-HPMC izobonisa inani layo eliyingqayizivele emikhakheni eminingi.
