Ukusetyenziswa
Uncedo lokucoca: Iarhente yokuthintela ukugabha, i-binder; Iarhente yokwandisa; I-Disintegrant; I-Dispersant; I-Texture iphucula; Iarhente yokuqinisa; Iarhente yokucoca amanzi. Ichazwe yi-EEC yokucoca ibhiya. Njengoko kuchaziwe kwi-GB 2760-96, ithathwa njengoncedo lokucubungula. Ngokwemigaqo ye-EEC-HACSG, ayizukusetyenziswa ekutyeni kweentsana. Njengearhente yokuthintela ukugabha, eTshayina, ivumelekile ukuba isetyenziswe kwiincasa zomgubo ezinokusetyenziswa okuphezulu kwe-50g/kg; ingasetyenziswa nakwi-ayisikhrim enokusetyenziswa okuphezulu kwe-40g/kg; ingasetyenziswa nakwikhrim ekhaphukhaphu kunye nomgubo wamafutha emifuno enokusetyenziswa okuphezulu kwe-20.0g/kg. Xa amaqela e-hydroxyl kwi-cellulose macromolecule edlula kwiimpendulo ze-esterification okanye ze-etherification, iimveliso ezininzi eziluncedo zinokufunyanwa. Ii-cellulose esters ezisetyenziswayo ziquka: i-cellulose nitrate, i-cellulose acetate, i-cellulose acetate butyrate kunye ne-cellulose xanthate. Ii-ether ze-cellulose ziquka: i-methyl cellulose, i-carboxymethyl cellulose, i-ethyl cellulose, i-hydroxyethyl cellulose, i-cyanoethyl cellulose, i-hydroxypropyl cellulose kunye ne-hydroxypropyl methyl cellulose, njl. Ukongeza, kukho izinto ezixutyiweyo ze-ester-ether. I-microcrystalline cellulose ingasetyenziswa kumashishini afana nempahla yokulahlwa, iimpahla, ukwenza ubhiya, ukutya, kunye nokwenza amaphepha.
I-microcrystalline cellulose ngokubanzi inoxinano oluphantsi kwiimveliso ezomisiweyo ngokuqandisa kunye noxinano oluphezulu kwiimveliso ezomisiweyo ngokufuthwa. Umxholo womswakama umalunga ne-5%. I-microcrystalline cellulose iyasasazeka kodwa ayinyibiliki emanzini, ayinyibiliki kwii-dilute acids, izinyibilikisi ze-organic kunye neeoyile, iyadumba kwaye inyibilike kancinci kwizisombululo ze-alkaline ezinyibilikisiweyo. Ukusasaza i-microcrystalline cellulose powder emanzini kuvelisa ijeli emhlophe ecacileyo okanye i-paste. Ngaphandle kwezo zinyibilikiswe kakhulu, ihlala izinzile iminyaka emininzi.
Ukupakishwa kunye nokuthunyelwa
njengeemfuno zabathengi.
Yeyokwempahla eqhelekileyo kwaye inokuhanjiswa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
