Cellulose ether ether ndi kalasi ya ma cellose omwe amasinthidwa mwanjira yamankhwala osinthika. Chifukwa cha kusungunuka kwamadzi abwino kwambiri, kusintha kwa ma vidiyo kukhala ntchito zakunja monga kutentha kwa kutentha ndi pH, amagwiritsidwa ntchito kwambiri pomanga, zokutira, mankhwala, zakudya ndi zodzola. Kuwongolera kwa ma viscle kuwongolera kwa cellulose ether ether ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale ambiri ndi tsiku lililonse.
1. Kapangidwe kake ndi kagulu ka cellulose
Cellulose ether ether amakonzedwa kuchokera ku cellulose yachilengedwe potengera mayere. Cellulose ndi polymer contround yopangidwa ndi monomers shune yolumikizidwa ndi β-1,4-Glycosidic. Njira yokonzekera ya ethel ether ether nthawi zambiri imaphatikizapo kugwiritsa ntchito ma hydroxyl (-Oh) gawo la cellulose ndi ma cellulose omwe amapanga cellulose, hydroxypropyl, etc.).
Kutengera ndi ma celluul ether overtures ofala kumaphatikizapo methyl cellulose (Mc), hydroxethyl celloull (cmc), ndi zinthu zina zosintha zina. Chiwerengerocho ndi udindo wa magawiti sizimangokhudza madzi otetemera a cellulose et, komanso molunjika ndi luso lawo lopanga machenjere.
2. Makina a Vivectotion
Mawonekedwe akuwongolera zotsatira za cellulose edzoza amabwera chifukwa cha kusungunuka kwawo m'madzi ndi machitidwe owonjezera amiyendo. Cellolilose eder amasungunuka m'madzi, magulu otakata amapanga matope a hydrogen ndi mamolekyulu am'madzi, zomwe zimapangitsa kuti maunyolo azitsulo kuti afotokozere m'madzi a cellulose, ndikuwonjezera kusokonekera kwamkati.
Kuchuluka kwa mafayilo kumakhudzana kwambiri ndi kulemera kwa maselo, kulowetsa mtundu wa zolowa m'malo mwa polymerization (DP) ya cellose. Nthawi zambiri, zokulirapo kulemera kwa cellulose etralose ndi kutalika kwa ma molecular, mawonekedwe owoneka bwino. Nthawi yomweyo, osiyanasiyana osiyanasiyana amakhudza hydrophilicity wa cellulose mtunda wa ethel, ndipo motero amakhudza kususuka kwawo ndikukukhumudwitsidwa m'madzi. Mwachitsanzo, HPMC ili ndi madzi abwino osungunuka ndi mawonekedwe a ma vincy chifukwa cha hydroxypyl ndi methyl m'malo. CMC, komabe, imakhala ndi mamasukidwe apamwamba chifukwa imayambitsa magulu osokoneza bongo omwe amalipidwa, omwe amatha kulumikizana kwambiri ndi mamolekyulu amadzi mu yankho la madzi.
3. Eff of East East pa MavisCence
Makutu a cellulose eyeliuluse amatengera kapangidwe kake, komanso chifukwa cha zinthu zakunja, kuphatikiza kutentha, ph mtengo wa pH, ion ndende, en.
3.1 kutentha
Kutentha ndi chinthu chofunikira chokhudza mafayilo a eleulse eyathe. Nthawi zambiri, mafayilo a ethel ether ether sol amachepetsa ndi kutentha kwambiri. Izi ndichifukwa choti kutentha kwambiri kumathandizira kusunthika kwa mamolekyulu, ndikuchepetsa kulumikizana kwa mamolekyulu, kumachepetsa ukadaulo wa cellulose m'madzi kuti muwonjezere mamolekyu amadzi, potero kuchepetsa ufa. Komabe, ma cellulose ena azungu (monga HPMC) Chuma)
3.2 PH mtengo
Mtengo wa pH umakhalanso ndi mphamvu kwambiri pakukweza kwa cellulose. Kwa cellulose enic miniti oyang'anira (monga cmc), mtengo wa pH umakhudza mkhalidwe wa miniti yam'manja, potero akukhudza kulumikizana pakati pa mamolekyulu ndi mafayilo. Pa mfundo zapamwamba Ngakhale kutsika kwa PHO, gulu la Carboxyl silimakhazikika, ma electrostatic amachepetsedwa, ma curls templs, ndipo ma virus amachepa.
3.3 ion ndende
Mphamvu ya ion ndende pakuwoneka kwa cellulose ether ether imawonekera kwambiri. Cellulose ether yokhala ndi ionic magantimitoni azikhudzidwa ndi zotsatira zoyipa za ma ion akunja. Pamene ion ndende yankho limawonjezeka, ma nthiwa yakunja adzafooketsa ma eleluyambitsa ma cellulose, ndikupangitsa kuti ma molekyuki a ma moleclucs ambiri, potero kuchepetsa mafayilo a yankho. Makamaka pamalo amchere chamchere, mawonekedwe a cmc atsika kwambiri, omwe ndi ofunika kwambiri kuti agwiritse ntchito.
4. Kuwongolera mafayilo mu magawo a ntchito
Cellulose ether yagwiritsidwa ntchito kwambiri m'minda yambiri chifukwa cha kusintha kwake kwa Iscment.
4.1 Zomangira
M'mabuku omanga, cellulose ether (monga hpmc) nthawi zambiri amagwiritsidwa ntchito matope osakanizika, putty ufa, zomata za matayala ndi zinthu zina kuti zisinthe madzi ndi zida zankhondo pomanga. Nthawi yomweyo, imathanso kuchedwetsa madzi, kusintha madzi osungirako zinthu, ndikusintha mphamvu ndi kukhazikika kwa chinthu chomaliza.
4.2 Zovala ndi Inks
Cellulose eds amakhala ngati oundana ndi okhazikika m'madzi ndi inks. Mwa kusintha mamasukidwe, amaonetsetsa kuti azolomedwe ndi kutsatira zigamba pomanga. Kuphatikiza apo, zingathandizenso kuwononga kotsutsana ndi zokutira, kumachepetsa kusaka, ndikupanga zomangazo kukhala yunifomu.
4.3 mankhwala ndi chakudya
Mu minda ya mankhwala ndi chakudya, cellulose et (monga hpmc, cmc) nthawi zambiri zimagwiritsidwa ntchito ngati otsatsa, emulsifiers kapena okhazikika. Mwachitsanzo, hpmc, monga zokutira mapiritsi, zitha kukwanitsa kumasula mankhwala pakuwongolera kuchuluka kwa chilengedwe. Mu chakudya, masentimita amagwiritsidwa ntchito kuwonjezera kuwoneka ngati kuwoneka, sinthani kukoma, ndi kuwonjezera moyo wa alumali.
4.4 zodzikongoletsera
Kugwiritsa ntchito cellose etrase mu zodzola kumadalira zinthu monga emulsions, ma gels ndi nkhope. Mwa kusintha mamasukidwe, cellulosese yokhala ndi mitundu yosiyanasiyana yamafuta ndi kapangidwe kake, ndikupanga filimu yonyowa pakhungu kuti iwonjezere chitonthozo.
Cellulose ether ether amatha kuwongolera chidwi cha njira zothetsera mavuto ake komanso kuyankha zachilengedwe zakunja. Izi zadzetsa ntchito yogwiritsidwa ntchito ndi ntchito zambiri m'minda monga zomanga, mankhwala, chakudya, ndi zodzola. Ndi kukula kosalekeza kwa sayansi ndi ukadaulo, ntchito za cellulose edell idzakulitsidwanso kuti ipereke njira yolondola ya ma visa owongolera minda yambiri.
