Ukusetshenziswa
Usizo lokuhlunga: I-ejenti yokulwa nokubhaka, i-binder; I-ejenti yokuhlanganisa; I-Disintegrant; I-Dispersant; I-Texture ithuthukisa; I-ejenti yokujiya; I-ejenti yokwelapha amanzi. Ichazwe yi-EEC ukuze kuhlanzwe ubhiya. Njengoba kuchaziwe ku-GB 2760-96, ibhekwa njengosizo lokucubungula. Ngokwemithetho ye-EEC-HACSG, akufanele isetshenziswe ekudleni kwezingane. Njenge-ejenti yokulwa nokubhaka, eShayina, ivunyelwe ukusetshenziswa kuma-flavour ayimpuphu anokusetshenziswa okuphezulu okungu-50g/kg; ingasetshenziswa futhi ku-ayisikhilimu enokusetshenziswa okuphezulu okungu-40g/kg; ingasetshenziswa futhi kukhilimu olula kanye nempuphu yamafutha emifino enokusetshenziswa okuphezulu okungu-20.0g/kg. Lapho amaqembu e-hydroxyl ku-cellulose macromolecule edlula esterification noma etherification reactions, imikhiqizo eminingi ewusizo ingatholakala. Ama-ester e-cellulose asetshenziswayo empeleni afaka: i-cellulose nitrate, i-cellulose acetate, i-cellulose acetate butyrate kanye ne-cellulose xanthate. Ama-ether e-cellulose afaka: i-methyl cellulose, i-carboxymethyl cellulose, i-ethyl cellulose, i-hydroxyethyl cellulose, i-cyanoethyl cellulose, i-hydroxypropyl cellulose kanye ne-hydroxypropyl methyl cellulose, njll. Ngaphezu kwalokho, kunezinhlobo ezixubile ze-ester-ether. I-microcrystalline cellulose ingasetshenziswa ezimbonini ezifana nezendwangu, izingubo, ukwenza ubhiya, ukudla, kanye nokwenza amaphepha.
I-microcrystalline cellulose ngokuvamile inobuningi obuphansi bemikhiqizo eyomisiwe eqandisiwe kanye nobuningi obuphezulu bemikhiqizo eyomisiwe efuthwayo. Okuqukethwe komswakama kungaba ngu-5%. I-microcrystalline cellulose iyahlakazeka kodwa ayincibiliki emanzini, ayincibiliki kuma-asidi ancibilikisiwe, izinyibilikisi eziphilayo kanye namafutha, iyavuvukala futhi incibilike kancane ezixazululweni ze-alkaline ezincibilikisiwe. Ukuhlakaza i-microcrystalline cellulose powder emanzini kuveza ijeli noma i-paste emhlophe ecacile. Ngaphandle kwalezo ezincibilikisiwe kakhulu, ihlala izinzile iminyaka eminingi.
Ukupakisha Nokuthumela
njengezidingo zamakhasimende.
Kungokwempahla evamile futhi kungathunyelwa ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
