1. Yintoni i-hydroxypropyl methylcelcelceluplose?
Hydroxypropyl methylcelculose (hpmc)Ngaba i-nor-i-no-i-ion-i-ion-i-ionsulsese i-ether, isetyenziswe ngokubanzi kwizinto zokwakha, ukutya, amayeza, cosmetics kunye namanye amasimi. Inemisebenzi yokuthambisa, ukugcinwa kwamanzi, ukuqulunqwa kwefilimu, ukungqubana, ukwenyuka kunye nokunqunyanyiswa, kwaye kunokunyibilika emanzini ukwenza isisombululo esibonakalayo okanye sokudumisa.
2. Ukusetyenziswa okuqhelekileyo kunye nokusetyenziswa kwe-HPMC
Ifildi yokwakha
I-HPMC isetyenziswa ngokuqhelekileyo kwizokwakha izinto ezinjengokuthengiswa kwesamente, umgubo we-posty, i-tile.
Umsebenzi
Indlela yokusetyenziswa:
Yongeza ngokuthe ngqo kudaka oluxubeneyo, isixa esicetyiswayo yi-0.1% ~ 0.5% yobunzima besamente okanye i-subsere;
Emva kokuvuselela ngokupheleleyo, yongeza amanzi kwaye uvuse ukufudumala.
Ishishini lokutya
I-HPMC inokusetyenziswa njenge-tickener, i-stabilizer kunye ne-emulsifier, kwaye ihlala ifumaneka ekutyeni njenge-ice cream, ijelly, isonka, njl.
Umsebenzi: Ukuphucula incasa, ukuzinzisa inkqubo, kwaye kuthintele ukorati.
Ukusetyenziswa:
Nyibilikisa amanzi abandayo, idosi ecetyiswayo ihlengahlengiswa phakathi kwe-0,2% ne-2% ngokodidi lokutya;
Ukufudumeza okanye umatshini wokuvuselela kunokukhawulezisa ukutshitshiswa.
Ishishini lamachiza
I-HPMC ihlala isetyenziswa kwithebhulethi yetafile, ithebhulethi yokukhutshwa kwetafile okanye i-capsule ye-capsule:
Umsebenzi: Ukuqulunqwa kwefilimu, ukulibaziseka ukukhutshwa ngamachiza, kunye nokukhusela umsebenzi weziyobisi.
Ukusetyenziswa:
Lungiselela kwisisombululo kunye ne-1% ukuya kwi-5%;
Phalaza ngokulinganayo kumphezulu wethebhulethi ukwenza ifilimu emdaka.
Cosmetics
I-HPMCisetyenziswa njenge-thickener, i-emulsion stabilizer okanye iarhente yefilimu, isetyenziswa ngokuqhelekileyo kwimaski yobuso, i-lotions, njl njl:
Umsebenzi: Ukuphucula ukuthungwa kunye nokomeleza iimvakalelo zemveliso.
Ukusetyenziswa:
Yongeza kwi-cosmetic matrix ngokulinganayo kwaye uvuselele ngokulinganayo;
Umthamo ngokubanzi yi-0.1% ukuya kwi-1%, uhlengahlengiso ngokweemfuno zemveliso.
I-3. Indlela yokuphelisa i-HPMC
Ukunyibilisela i-HPMC kuchaphazeleka kakhulu kubushushu bamanzi:
Kulula ukunyibilikisa amanzi abandayo kwaye kunokwenza isisombululo esilinganayo;
Inganyibiliki emanzini ashushu, kodwa inokusasazeka kwaye yenze i-colloid emva kokupholisa.
Amanyathelo athile okupheliswa:
Ukutshiza i-HPMC kancinci emanzini, kuphephe ukuthulula ngokuthe gala ukhusela i-cace;
Sebenzisa umnqweno wokudibanisa ngokulinganayo;
Lungisa i-ugxininiso lesisombululo njengoko kufuneka.
4. Izilumkiso zokusebenzisa i-HPMC
Ulawulo lwe-Dosage: Kwimeko ezahlukeneyo zesicelo, umthamo uchaphazela ngqo ukusebenza kwaye kufuneka avavanywe ngokweemfuno.
Iimeko zokugcina: Kufuneka zigcinwe kwindawo epholileyo, eyomileyo, enomoya yokuphepha ukufuma kunye nobushushu obuphezulu.
UKUKHUSELEKO IXESHA: I-HPMC yi-biodegrades kwaye ayingcolise indalo, kodwa kufuneka isetyenziswe ngendlela emiselweyo ukuthintela inkunkuma.
Uvavanyo oluhambelana:
I-5. Izibonelelo ze-HPMC
Engabinayo, ngokusingqongileyo, ukhuseleko oluphezulu;
Ukusebenza kwezinto zokusebenza, eziguquguqukayo kwiimfuno ezahlukeneyo;
Uzinzo oluhle, unokugcina intlalothuba ixesha elide.
I-6. Iingxaki eziqhelekileyo kunye nezisombululo
Ingxaki ye-Agglomeration: Nika ingqalelo ekubonakaliseni okusasazeka ngexesha lokusetyenziswa kunye nokuvuselela ngokupheleleyo ngaxeshanye.
IXESHA LOKUGQIBELA
Ukupheliswa kwentsebenzo: Nika ingqalelo imeko yokugcina ukuthintela ukufuma nobushushu.
Ngokusebenzisa i-HPMC kwaye ngokungxamisekileyo, iimpawu zayo ezininzi zinokusetyenziswa ngokupheleleyo ukubonelela ngezisombululo ezikumgangatho ophezulu kumashishini ahlukeneyo.
