1. Cellulose imadutsa d-glucopyranose β-mzere polymer wopangidwa ndi kulumikizana kwa 1,4 glycoside. Celluloser nevaner yokha ndi yozungulira kwambiri ndipo siyingakhale gelatinize m'madzi kapena kupangidwa mu nembanemba, motero ziyenera kusinthidwa motero. Hydroxyl yaulere pamalopo C-2, C-3 ndi C-6 amawavuta ndi ntchito yamankhwala ndipo imatha kukhala ndi maxidid, esteriquition ndi konkirelmerization. Kusungunuka kwa cellulose yosinthidwa kumatha kusintha ndipo kumakhala ndi magwiridwe abwino.
2. Mu 1908, ku Switzerena wa ku Switzer Texques Brandenberg adakonza ma cellulose oyamba a cellophalose, yomwe idachita kupanga chitukuko chamakono chofewa. Kuyambira 1980s, anthu anayamba kuphunzira nkhono yodzisinthidwa ngati kanema wabwino komanso wokutira. Cellulose ya celluuse yosinthidwa ndi chinthu cha nembanemba zomwe zimapangidwa kuchokera ku zotumphukira zomwe zidapezeka pambuyo posinthira mankhwala a cellulose. Mitundu iyi ya nembane ili ndi mphamvu yayikulu, kusinthasintha, kuwonekera, kutsutsana kwa mafuta, madzi osaneneka komanso osakaniza ndi mpweya.
3. CMC imagwiritsidwa ntchito mu zakudya zokazinga, monga ma fries achi French, kuti muchepetse kuyamwa kwa mafuta. Pamene imagwiritsidwa ntchito limodzi ndi calcium chloride, zotsatira zake zimakhala bwino. HPMC ndi MC amagwiritsidwa ntchito kwambiri pamafuta, makamaka chakudya chokazinga, chifukwa ndi ma gels. Ku Africa, MC, HPMC, mapuloteni a chimanga ndi Amylose amagwiritsidwa ntchito poletsa mafuta owoneka bwino kwambiri, monga kupopera mbewu mankhwalawa ndi kuwaza mayankho a nyemba zofiira kuti akonzekere mafilimu ofiira. Zinthu zoviikidwa mc membrane ndizothandiza kwambiri pakutchinga mafuta, zomwe zimachepetsa kuyamwa kwa mafuta ndi 49%. Nthawi zambiri, amaviikidwa zitsanzo zowoneka bwino zimawonetsa mafuta ochepera kuposa opopera.
4. MCNdipo HPMC imagwiritsidwanso ntchito pa zitsanzo zowuma monga mipira ya mbatata, kusenda chipika cha mbatata ndi mtanda kuti musinthe zotchinga, nthawi zambiri popopera. Kafukufukuyu akuwonetsa kuti MC ili ndi ntchito yabwino kwambiri yoletsa chinyezi ndi mafuta.it madzi osungitsa madzi makamaka chifukwa cha hydrophilicity yake. Kudzera mu maikulosikopu, zitha kuwoneka kuti filimu ya MC ili ndi chizodero chabwino kwa chakudya chokazinga. Kafukufuku wawonetsa kuti HPMC yokutidwa ndi nkhuku pamipira ya nkhuku imakhala ndi madzi abwino ndipo imatha kuchepetsa kwambiri mafutawo pakukazinga. Madzi omwe ali ndi zitsanzo zomaliza atha kuwonjezeka ndi 16.4%, pamtunda wamafuta amatha kuchepetsedwa ndi 17.9%, ndipo mafuta amkati amatha kuchepetsedwa ndi 33.7%. magwiridwe antchito aHpmc. Pa gawo loyamba la gel, mafayilo amawonjezeka kwambiri, kukhazikika kwa intermar kumachitika mwachangu, ndipo njira yothetsera mavuto a 50-90 ℃. Wosanjikiza gel osanjikira kusamukira kwa madzi ndi mafuta pakukazinga. Powonjezera hydrogeel kupita kunthanja yakunja ya nkhuku zokazinga zomwe zimavimidwa mu zitsamba za mkate zimatha kuchepetsa mavuto am'mawere a nkhuku ndikusunganso mawonekedwe a zitsanzo za sampu.
5. Pali zinthu ziwiri zomwe zimalepheretsa ntchito yake: Choyamba, ndi gel yosalimba ngati gelsicticing ngati gel osakaniza kutentha kwambiri kutentha kwa firiji. Zotsatira zake, matrix ayenera kukhazikitsidwa ndikuwuma pamtunda wapamwamba panthawi yokonzekera. Kupanda kutero, pakupanga makulidwe, kupopera mbewu mankhwalawa kapena kuyika, yankholi ndi losavuta kutsika, ndikupanga zida zosasinthika, zomwe zikukhudza mafilimu osinthika. Kuphatikiza apo, opaleshoniyi kuyenera kuwonetsetsa kuti malo onse opanga mapulogalamu amasungidwa pamwamba pa 70 ℃, kuwononga kutentha kwambiri. Chifukwa chake, ndikofunikira kuchepetsa gel point kapena kuwonjezera chidwi chake kutentha kochepa. Chachiwiri, ndiokwera mtengo kwambiri, pafupifupi 100000 yuan / one.
