Cellulose ndiye gawo lalikulu la makhoma a cell, ndipo ndi polysaride kwambiri komanso kuchuluka kwambiri kwachilengedwe, kumawerengera zoposa 50% ya mpweya womwe uli mu ufumu wa chomera. Pakati pawo, kuchuluka kwa kanyumba ka thonje kuli pafupi ndi 100%, komwe kumakhala korolose kwambiri zachilengedwe. M'matanda ambiri, maakaunti a cellulose pa 40-50%, ndipo pali 10-30% Hemithellulose ndi 20-30% Lignamin. Cellulose ether ndi nthawi yayikulu yochokera ku mitundu yosiyanasiyana yopezeka kuchokera ku cellulose yachilengedwe ngati yophika kudzera kusinthika. Ndi chinthu chomwe chimapangidwa pambuyo pa magulu a hydroxyl pa celrouler macrolecles ndiwosinthidwa pang'ono ndi magulu a ether. Pali maunyolo a intra-ulerogen mu cellulose macromolenules, omwe ndi ovuta kusungunuka m'madzi ndipo pafupifupi madera onse amasungunuka ndipo amawonjezera kusungunuka m'madzi ndi okhazikika. Zosintha.
Cellulose Ether ali ndi mbiri ya "mafakitale a Mafakitale a Mafakitale". Ili ndi chinthu chabwino monga yankho limakulirakulira, madzi osungunuka bwino, kuyimitsidwa kapena kukhazikika kwa mafilimu, kapangidwe ka filimuyo, kusungidwa kwamadzi, kusungidwa kwamadzi. Ilinso yopanda zoopsa komanso yopanda pake, ndipo imagwiritsidwa ntchito kwambiri popanga zinthu zomanga, mankhwala, zovala zamankhwala tsiku lililonse, migodi, mapepala ambiri. Cellulose ether ali ndi maubwino ambiri ogwiritsira ntchito, kugwiritsa ntchito kagawo kameneka, kusintha kwabwino, komanso kucheza ndi chilengedwe. Imatha kusintha kwambiri ndikutha kukweza magwiridwe antchito ake, omwe ali oyenera kusintha magwiridwe antchito ndi ntchito yowonjezera. Zowonjezera zachilengedwe zowonjezera zomwe ndizofunikira m'minda yosiyanasiyana.
Malinga ndi kununkhira kwa cellulose ether, mtundu wa magalamumu komanso kusiyana kwa solubility, cellulose ether amatha kulembedwa m'magulu osiyanasiyana. Malinga ndi mitundu yosiyanasiyana ya magantimiti, cellulose eders amatha kugawidwa kukhala amodzi ndi osakanikirana nawo. Malinga ndi kusungunuka, cellulose ether imatha kugawidwa m'madzi osungunuka ndi osakhazikika. Malinga ndi anization, imatha kugawidwa mu Ionic, zosagwirizana ndi ionic ndi zosakanikirana. Pakati pa cellulose yosungunuka yam'madzi, cellulose yopanda inic imakhala ndi kutentha kwabwino kwambiri kukana ndi kusanthula mchere celluse yolimba eya (cmc).
Kodi ma celluuse erede bwanji ogulitsa?
Cellulose ether imapangidwa kuchokera ku thonje yoyenga kudzera mu ma alkirization, kuyeretsedwa ndi masitepe ena. Kupanga kwa gawo la garmaceutical hpmc ndi chakudya gpmc ndendende. Poyerekeza ndi ma cellulose opanga ma cellulose, njira zopangira ma garmaceutical-greac hpmc ndi kalasi hpmc yomwe imafunikira kuti athetse, ndizovuta kuwongolera, ndipo zimafunikira ukhondo waukulu wopanga.
Malinga ndi zomwe zaperekedwa ndi Cellulose mabungwe omwe sanali opanga ether ether equic celly opanga nyumba, monga Herkles Hussic, Shandong Heda, ndi zina zambiri. Pali mitundu ina yambiri yopanda inic eyer yopanga matani opanga matani 4,000. Kupatula mabizinesi ochepa, ambiri aiwo amapatsana katundu wamba wa celluse, ndikupanga mphamvu zokwanira pafupifupi matani pafupifupi 100,000 pachaka. Chifukwa cha kusowa kwa mphamvu zachuma, mabizinesi ang'onoang'ono ambiri amalephera kukwaniritsa zotetezera zachilengedwe mu chilengedwe m'madzi ndi mankhwala ochizirawo kuti achepetse ndalama zopangira. Monga dzikolo ndi gulu lonselo limalipira kwambiri kutetezedwa kwa chilengedwe, mabizinesiwo m'makampani omwe sangakwaniritse chitetezo zachilengedwe chidzatsekedwa pang'onopang'ono kapena kuchepetsa kupanga. Panthawiyo, kuchuluka kwa malo anga a celluse opanga elewel opanga ma cellose opanga ma celluuse kudzawonjezeka.
Ndondomeko zachilengedwe zachilengedwe zikuyamba kukhazikika, ndipo zomwe zimasungidwa mosamala zimayikidwa patsogolo pazaukadaulo wofunafuna zachilengedwe komanso ndalama zogulitsa mu cellulose ether ether ether ether ether. Njira zotetezera zachilengedwe zimakulitsa mtengo wopanga mabizinesi komanso kupanga njira yayikulu yotetezedwa zachilengedwe. Mabizinesi omwe sangathe kukwaniritsa zofunika kuteteza chilengedwe lidzatsekedwa pang'onopang'ono kapena kuchepetsa kupanga chifukwa cholephera kukwaniritsa miyezo yoteteza zachilengedwe. Malinga ndi kusowa kwa kampani, mabizinesi omwe pang'onopang'ono amachepetsa kupanga ndikusiya kupanga zachilengedwe kumatha kukhala ndi matani pafupifupi 30,000
Kutengera ndi cellulose ether, imapitilirabe mpaka pamapeto okwanira komanso owonjezera owonjezera
