Cellulose elter ndi gulu la ma polymer ma polmer omwe amaperekedwa ndi mankhwala a cellulose, omwe amagwiritsidwa ntchito kwambiri popanga zinthu zomanga, mankhwala, chakudya, zokutira ndi minda ina. Zogwirizira za cellulose zimagwirizana kwambiri ndi mtundu wa magalamu, kuchuluka kwa kuloweza ndi kulemera kwamitundu. Ali ndi malo apadera komanso mitundu yosiyanasiyana.
1. Katundu wa cellulose et
Kusalola
Chifukwa cha kukhazikitsidwa kwa magawatimini, cellulose etter zimaswa mabotolo amphamvu pakati komanso mkati mwa mamolekyulu achilengedwe, kuwapangitsa kuti azisungunuka m'madzi kapena okhazikika. Mitundu yosiyanasiyana ya cellulose imakhala ndi kusungunuka kosiyanasiyana:
Hydroxypylmyl nothycellulose (hpmc): kusungunuka m'madzi ozizira, osauzidwa m'madzi otentha, koma mitundu gel m'madzi otentha.
Carboxymethyl cellulose (cmc): kusungunuka mosavuta m'madzi ozizira komanso otentha, ndi zida zabwino kwambiri.
Kukula ndi Nfine
Pambuyo kusungunula, cellulose etress kupanga njira yapamwamba kwambiri ya mafayilo abwino kwambiri. Khalidwe lake lachibelo lazikhalidwe limatha kusintha kusintha kwa kukhazikika kwamitundu ndi kumeta ubweya, kuwonetsa madzi a pseudoplastic, omwe ali oyenera kusintha madzi ndi kukhazikika kwa mafakitale.
Kupanga filimu ndi zomatira
Cellulose Ede amatha kupanga filimu yowoneka bwino pamwamba pa gawo la gawo la gawo limodzi, ndikusinthasintha kwamadzi, ndipo ndioyenera kugwiritsa ntchito zokutira ndi zida zapamalo. Nthawi yomweyo, imakhala ndi kutsatira kwambiri ndipo imatha kugwiritsidwa ntchito ngati binder.
Bata
Cellulose eds ndi okhazikika m'mawu osiyanasiyana ndikulimbana ndi acid acid ndi alkali. Nthawi yomweyo, mphamvu zake zamankhwala zimakhala zokhazikika, sizimawonongeka mosavuta ndi tizilombo tambiri, ndipo zimatha kugwira ntchito kwa nthawi yayitali.
Miyala yotentha
Ma cellulose ena azungu (monga Hopmc) adzapangitsa kuti yankho likhale turbid kapena gel mukatenthedwa. Katunduyu amagwiritsidwa ntchito kwambiri pantchito yomanga ndi chakudya.
2. Kugwiritsa ntchito cellose etrase
Nyumba zomangira
Cellulose eders amagwiritsidwa ntchito ngati otsatsa, madzi osungira madzi ndi ma comanga pomanga zida. Chitetezo chake chamadzi chimakhala bwino pamagetsi omanga matope a simenti ndi gypsum, amathandizira opareshoni, ndipo amalepheretsa ming'alu. Ntchito zapaderazo zikuphatikiza:
Matope a simenti: Sinthanitsani kufooka, kuthandizira zomatira ndi madzi omanga.
Kumatira kwa Tale: Kulimbikitsa kulimbikira mphamvu ndikuwongolera kukhazikika.
Zinthu zofiirira ndi mankhwala a gypsum: Sinthani zomangamanga, kuwonjezera madzi kusungidwa ndi malo osungirako pansi.
Gawo Lachipatala
Cellulose eder amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, makamaka monga othandizira mapiritsi, kusokoneza, osokoneza bongo okhala ndi zoletsedwa ndi zophika. Mwachitsanzo:
Hydroxypropyl methylcellulose (hpmc): Monga zopangira zazikulu za zipolopolo zazikulu, zimalowa m'malo mwa gelatin kuti tikwaniritse zosowa za gelatin.
Hydroxyethyl cellulose (hec): Ankakonda kukonzekera kuyimitsidwa kwa mankhwala ndi madontho amaso.
Makampani Ogulitsa Chakudya
Cellulose edirs ndi zowonjezera zowonjezera mu malonda azakudya, ndikukula, kukhazikika, kukhazikika, emulsization ndi madzi osunga madzi.
Amagwiritsidwa ntchito mu ayisikilimu, soseces ndi ma jellles kuti muchepetse kukoma ndi kapangidwe kake.
Ogwiritsidwa ntchito ngati chonyowa mu katundu wophika kuti muchepetse ukalamba ndi kusweka.
Zovala ndi Inks
Cellulose exem nthawi zambiri amagwiritsidwa ntchito ogulitsa ndi a rheology oyang'anira mu makampani okutira, omwe amatha kukonza mafano ndi zokutira ndikupewa utoto wa pigment. Nthawi yomweyo, monga thandizo lopanga mafilimu, limasintha magwiridwe antchito.
Zogulitsa tsiku ndi tsiku
M'malo otsekemera, zodzoladzola komanso zinthu zosamalira payekha, cellulose stars zimagwiritsidwa ntchito ngati masamba ndi okhazikika. Mwachitsanzo, ma carbostethymethymethyl cellulose (cmc) amatha kupereka kusasinthika koyenera komanso kukhazikika kwa phala.
Magawo ena
Cellulose eder amathanso kugwiritsidwanso ntchito paulimi (mankhwala ophera tizilombo), makampani ogulitsa mafuta (mabowo amadzimadzi) ndi mafakitale opanga mapangidwe (kusindikiza ndi kupangira alexiliaries).
Cellulose engers amachita mbali yofunika kwambiri m'makampani osiyanasiyana ndi ntchito zawo zabwino komanso zosiyanasiyana. Ndi kukula kwaukadaulo wa cellulose eleluse, madera ake ogwiritsa ntchito adzakulitsidwa ndikuchita mbali yofunika kwambiri mu chitukuko chokhazikika komanso chemistry.
