Intshayelelo

Microcrystalline cellulose (Microcrystallinecellulose, MCC) yi-cellulose yendalo nge-acid hydrolysis ukunciphisa imveliso yeqondo le-polymerization, umbala wayo umhlophe okanye phantse umhlophe ngeChemicalbook, engenabungozi, engenancasa, ubungakanani bamasuntswana ngokubanzi malunga ne-2 ~ 80 microns, Inayo izibonelelo zoxinaniso oluphantsi, iimodyuli eziphezulu, ezinokuhlaziywa, ezinokuthotywa, umthombo obanzi njalo njalo. Ingasetyenziselwa ukuqinisa iarhente ukuphucula iipropathi zezinto ezidityanisiweyo.

Umntu

Ngokubanzi, ukuxinana kwe-microcrystalline cellulose kusezantsi kwi-cellophose ene-lyophilized kwaye iphezulu kwi-cellulose eyomileyo. Umxholo wobumanzi umalunga ne-5%. I-Microcrystalline cellulose iyasasazeka kodwa ayinyibiliki emanzini, ayinyibiliki kwizidibanisi ze-asidi, izinyibilikisi ze-organic kunye neoyile, iyadumba kwaye inyibilika ngokuyinyibilikisa kwizisombululo zealkaline. Ngokusasaza i-microcrystalline cellulose powder emanzini, i-gel emhlophe ebonakalayo okanye unamathisele unokufunyanwa, ohlala uzinzile iminyaka emininzi ngaphandle kwezinto ezinqabileyo kakhulu.
ipropathi yamachiza: L, 4-bonded glucose isiseko sepolymer. Into emhlophe engenancasa engenancasa, equkethe amasuntswana eselulosi, inokucinezelwa kwithebhulethi esasazeka ngokukhawuleza emanzini ngokudibana kwayo. Kukho amanqanaba ngamanqanaba, asusela kwi-powders eshinyeneyo, engena simahla ukuya kurhabaxa, iflu Chemicalbook, izinto ezingahambiyo. Ingenakunyibilika emanzini, inyibilikise iiacidi, kwaye phantse zonke izinyibilikisi eziphilayo. Yinyibilike kancinci kwisisombululo sehydroxidide kunye nesisombululo esine-casein eshushu. Inepropathi ye-hydrophilic kunye ne-lipophilic, enokudumba ibaleke emanzini kwaye ihlawuliswe kakubi, ke iyakwazi ukubhengeza ii-ion zentsimbi kunye nezinto ze-cationic kwisisombululo.

Sebenzisa

Uncedo lwe-1. Ukudityaniswa. Ukophuka; Iyasasazeka; Ukuphucula izicubu; Ukujiya; Ummeli wonyango lomgangatho wamanzi. Imigaqo ye-EEC yokuhlanjululwa kwebhiya. I-GB 2760-96 ichazwa njengoncedo lokuqhubekeka. Imigaqo ye-EEC-HACSG akufuneki isetyenziswe ekutyeni komntwana.
I-2Applicable to textile, impahla, ukupheka, ukutya, iphepha kunye namanye amashishini
3.Iadhesives, disintegrants kunye nezongezo zokutya ezisetyenziselwa ukucofa ngokuthe ngqo kwithebhulethi
4. Ingasetyenziselwa i-ice cream, ukusetyenziswa okuphezulu yi-40g. Ikg; Ingasetyenziselwa ukhilimu omncinci kunye nomgubo onamafutha, ukusetyenziswa okuphezulu yi-20.0g / kg.
Ummeli we-5. Emulsifier; Umatshini; Ukophuka; Iyasasazeka; Ukuphucula izicubu; Igosa elingasondliyo; Ifayibha yokutya; Ukuzinzisa ukungqinisisa; Somlilo Ubushushu; Ukomisa ngokukhawuleza othwala; Umahluko womgubo kunye nethebhulethi yeChemicalbook. Ngokwemigaqo ye-EEC, inokusetyenziselwa isonka esinefayibha ephezulu; Iilekese eziphantsi kweekhalori, iibhiskithi, iikeyiki kunye nezonka; Iifilitha zombala, incasa kunye neeasidi ezityiwayo; Ukutya okungamanzi emzimbeni, ukutya okutyiwa kunye nezilayi zeziqhamo zebionic, njl.
Iimveliso ezininzi eziluncedo zinokufunyanwa kwi-esterification okanye kwi-etherification yamaqela ehydroxyl kwiipholima zeselulosi.
7.Ukwenza i-nitric acid okanye i-cellulose acetate. Ikholam chromatography. Isetyenziselwa ukuhluza
