Kushandiswa
Rubatsiro rwekusefa: Mushonga wekudzivirira kubikwa kwedoro, muchina wekubatanidza; Mushonga wekuwedzera; Mushonga wekubvisa tsvina; Mushonga wekubvisa tsvina; Mushonga wekuvandudza magadzirirwo; Mushonga wekuchenesa mvura. Yakatsanangurwa neEEC yekuchenesa doro. Sezvakatsanangurwa muGB 2760-96, inoonekwa semushonga wekugadzirisa. Sekureva kwemitemo yeEEC-HACSG, haifanirwe kushandiswa muzvikafu zvevacheche. Semushonga wekudzivirira kubikwa kwedoro, muChina, inobvumirwa kushandiswa muzvinonhuwira zveupfu zvine huwandu hwakanyanya hwe50g/kg; inogona zvakare kushandiswa mu ice cream ine huwandu hwakanyanya hwe40g/kg; inogona zvakare kushandiswa mu cream light nemafuta emuriwo ane huwandu hwakanyanya hwe20.0g/kg. Kana mapoka ehydroxyl ari mu cellulose macromolecule akaitwa esterification kana etherification, zvigadzirwa zvakawanda zvinobatsira zvinogona kuwanikwa. Cellulose esters dzinoshandiswa dzinosanganisira: cellulose nitrate, cellulose acetate, cellulose acetate butyrate uye cellulose xanthate. Cellulose ethers dzinosanganisira: methyl cellulose, carboxymethyl cellulose, ethyl cellulose, hydroxyethyl cellulose, cyanoethyl cellulose, hydroxypropyl cellulose uye hydroxypropyl methyl cellulose, nezvimwewo. Pamusoro pezvo, kune zvinhu zvakasanganiswa zve ester-ether. Microcrystalline cellulose inogona kushandiswa mumaindasitiri akadai semachira, mbatya, kugadzira doro, chikafu, uye kugadzira mapepa.
Microcrystalline cellulose inowanzova nehuwandu hwakaderera hwezvinhu zvakaomeswa nechando uye huwandu hwakanyanya hwezvinhu zvakaomeswa nespray. Hunyoro hwayo hunosvika 5%. Microcrystalline cellulose inonyungudika asi hainyungudike mumvura, hainyungudike mu dilute acids, organic solvents nemafuta, inozvimba uye inonyungudika zvishoma mu dilute alkaline solutions. Kuparadzira microcrystalline cellulose powder mumvura kunoburitsa gel chena inoonekera kana paste. Kunze kweiyo yakanyanyiswa zvakanyanya, inoramba yakasimba kwemakore mazhinji.

Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
