Kagwiritsidwe Ntchito
Chithandizo cha zosefera: Choletsa kukhetsa, chomangirira; Chowonjezera mphamvu; Chochotsa madzi m'thupi; Chochotsa mpweya m'thupi; Chowonjezera kapangidwe kake; Chowonjezera mphamvu; Chothandizira kukonza madzi. Chimayikidwa ndi EEC kuti chiyeretse mowa. Monga momwe zalembedwera mu GB 2760-96, chimaonedwa ngati chothandizira kukonza. Malinga ndi malamulo a EEC-HACSG, sichiyenera kugwiritsidwa ntchito mu chakudya cha ana. Monga choletsa kukhetsa, ku China, chimaloledwa kugwiritsidwa ntchito mu ufa wokhala ndi mphamvu yokwana 50g/kg; chingagwiritsidwenso ntchito mu ayisikilimu wokhala ndi mphamvu yokwana 40g/kg; chingagwiritsidwenso ntchito mu kirimu wopepuka ndi ufa wamafuta a masamba wokhala ndi mphamvu yokwana 20.0g/kg. Pamene magulu a hydroxyl mu cellulose macromolecule akumana ndi esterification kapena etherification, zinthu zambiri zothandiza zimatha kupezeka. Ma cellulose esters omwe amagwiritsidwa ntchito ndi awa: cellulose nitrate, cellulose acetate, cellulose acetate butyrate ndi cellulose xanthate. Ma cellulose ethers akuphatikizapo: methyl cellulose, carboxymethyl cellulose, ethyl cellulose, hydroxyethyl cellulose, cyanoethyl cellulose, hydroxypropyl cellulose ndi hydroxypropyl methyl cellulose, ndi zina zotero. Kuphatikiza apo, pali zinthu zosakanikirana za ester-ether. Microcrystalline cellulose ingagwiritsidwe ntchito m'mafakitale monga nsalu, zovala, kupanga mowa, chakudya, ndi kupanga mapepala.
Maselo a microcrystalline cellulose nthawi zambiri amakhala ndi kuchuluka kochepa kwa zinthu zouma mufiriji komanso kuchuluka kwakukulu kwa zinthu zouma mufiriji. Chinyezi chake ndi pafupifupi 5%. Maselo a microcrystalline cellulose amatha kusungunuka koma sangasungunuke m'madzi, sangasungunuke mu ma acid osungunuka, zinthu zosungunuka zachilengedwe ndi mafuta, amatupa ndikusungunuka pang'ono mu mayankho a alkaline osungunuka. Kutulutsa ufa wa microcrystalline cellulose m'madzi kumapanga gel yoyera yowonekera kapena phala. Kupatula omwe amasungunuka kwambiri, amakhalabe olimba kwa zaka zambiri.
Kulongedza ndi Kutumiza
monga zofunikira kwa makasitomala.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
