Ndi methyl cellulose orlulose ether ether?

Mafala Akutoma Nawo Elemerese:
Cellulose ndi imodzi mwazinthu zochulukirapo zachilengedwe padziko lapansi, zopezeka m'makoma a cell azomera. Ndipo polysaccharide yopangidwa kuti ikubwereza mayunitsi a glucose omwe adalumikizidwa pamodzi ndi β (1 → 4) zomangira. Cellulose imachokera ku cellulose, komwe mmodzi kapena angapo a magulu a hydroxyl (-Oh) amalowa m'malo ndi madera a Ether (-). Izi zopindika zimasintha zinthu zakuthupi ndi mankhwala a cellulose, zomwe zimapangitsa kuti zikhale zoyenera zamagetsi zosiyanasiyana.

Methyl cellulose: Tanthauzo ndi kapangidwe:
Methyl cellulose ndi ether ether yochokera ku cellulose kudzera m'magulu a hydroxyl ndi methyl. Izi zimapangitsa poilymer ndi kusungunuka bwino mosintha m'madzi ndi polar sol soldent poyerekeza ndi cellulose. Mulingo wazolowa (DS) amatanthauza kuchuluka kwa magulu a hydroxyl omwe adasinthidwa ndi magulu a methelose pa ulalo wa glucose mu cellulose mu celyll cellulose.

Kapangidwe ka mankhwala kwa methyl cellulose amatha kukhala yosiyanasiyana kutengera kuchuluka kwa milingo yolowa m'malo mwa methel m'maguluwo. Nthawi zambiri, methyl cellulose mamolekyulu ndi ma polima okhala ndi maunyolo osinthika, kuwalola kuti apange njira zothetsera mavuto amtundu wambiri.

Kupanga:
Methyl cellulose nthawi zambiri imapangidwa kudzera mu ma cellulose ndi methyl chloride kapena methyl sulfate pamaso pa caltaly. Zomwe zimapangitsa kuti zithandizire magulu a hydroxyl ndi ma ethyl magemu, zomwe zimapangitsa celyl cellulose. Mlingo wazolowa mukhoza kuwongolera mwa kusintha zomwe zimachitika monga kutentha, nthawi ya machitidwe, ndi kuchuluka kwa cellulose ku methylaose wothandizira.

Pambuyo pa kaphatikizidwe, malonda omwe amayeretsa mapulogalamu kuti achotse zodetsa komanso zopangidwa ndi zinthu. Izi zingaphatikizepo kutsuka, kusefera, ndi kuwuma njira kuti mupeze methyl cellulose ufa kapena granules.

Katundu wa methyl cellulose:
Methyl cellulose imawonetsa malo angapo omwe amapangitsa kuti ikhale yoyenera kwa ntchito zosiyanasiyana:

Kusungunuka kwamadzi: methyl cellulose amasungunuka m'madzi ozizira, ndikupanga zomveka, ma viscous. Kusungunuka kumatha kukulimbikitsidwa ndikuwonjezera kuchuluka kwa malo osokoneza.

Kukhazikika kwamafuta: methyl cellulose ndiwokhazikika, ndikusunga zida zamagetsi zosiyanasiyana. Katunduyu amapangitsa kuti ikhale yoyenera pamapulogalamu omwe amafunikira kukana kutentha.

Mapangidwe a filimu: methyl cellulose imatha kupanga mafilimu osinthika, owoneka bwino atachotsa yankho. Makanema awa ali ndi zotchinga zabwino ndikupeza mapulogalamu pazokutira ndi zida zapamalo.

Kukula ndi kuphatikizira: methyl cellose imagwira ntchito yolimbitsa thupi m'matumba am'madzi, kuwonjezera mamasukidwe ndikusintha kapangidwe kake. Ikhozanso kufooketsa ma gels osinthika mozama kwambiri, omwe ndi othandiza pazakudya ndi mankhwala opangira mankhwala.

Ntchito: Methyl cellulose imawonetsa katundu wogwira ntchito, yomwe imatha kugwiritsidwa ntchito mu emulsization ndi kukhazikika kwa makina a Colloidal.

Mapulogalamu a Methyl cellulose:
Methyl cellulose imapeza ntchito zofala pamakampani osiyanasiyana chifukwa cha zomwe zimachitika:

Makampani Ogulitsa Chakudya: Makampani ogulitsa zakudya, methyl cellulose imagwiritsidwa ntchito ngati wothandizira, okhazikika, ndi emulsifier mu zinthu monga msuzi, zovala, zinthu zotsekemera. Imakhala bwino kapangidwe kake, imathandizira pakamwa, ndipo imangokhala kukhazikika kwaulere.

Mankhwala ogulitsa: Methyl cellulose imagwiritsidwa ntchito kwambiri pamitundu yosiyanasiyana monga bander, kusazindikira, ndi kusungiramo mapiritsi ndi makapisozi. Itha kugwiritsidwanso ntchito kwambiri monga ma gels, mafuta, mafuta chifukwa cha kukula kwake komanso kwamitundu.

Ntchito Yomanga: Methyl cellulose imagwiritsidwa ntchito popanga zomanga monga matope, pulasitala, ndi tiles ngati othandizira okhazikika ndi owonjezera madzi. Imakhala bwino ntchito, kutsatira, ndipo imalepheretsa kusanja kwa zosakaniza zonyowa.

Zodzikongoletsera: Mu zodzikongoletsera komanso zopangidwa ndi zinthu zapadera, methyl cellose imagwiritsidwa ntchito popanga monga zonona, zotupa, ma shampoos, ndi mankhwala osungunuka, komanso othandizira mafilimu. Imapereka mphamvu ya ufa, imathandizira kapangidwe kake, ndikusintha magwiridwe antchito.

Ntchito za mafakitale: methyl cellulose imagwiritsidwa ntchito pakugwiritsa ntchito mafayilo osiyanasiyana monga kusindikiza kwa pepala, zokutira pepala, ndi mawonekedwe opindika, komanso mawonekedwe opanga makanema.

Zotsatira za chilengedwe:
Ngakhale methyl cellulose nthawi zambiri amawoneka otetezeka kuti agwiritse ntchito chakudya, mankhwala opangira mankhwala, ndi mapulogalamu ena, zotsatira zake ziyenera kulingaliridwa mosamala. Cellulose elidlers oyipitsidwa ochokera ku zinthu zokonzanso, ndikuwapangitsa kukhala ochezeka poyerekeza ndi oyipitsa ma politymers. Komabe, kupanga kapangidwe kake kungaphatikizepo kugwiritsa ntchito mankhwala ndi mphamvu, kumathandizira kuipitsidwa ndi chilengedwe ndi mpweya wowonjezera kutentha.

Kuyesayesa kukupangitsani kukonza zokhazikika za eleeluse eleather pogwiritsa ntchito njira zobiriwira, mphamvu zobwezeretsedwanso, ndikubwezeretsanso zinthu. Kuphatikiza apo, katundu wa methyl cellulose-yokhala ndi malo opezeka amayenera kuchepetsedwa moyenera kuti muchepetse kuipitsa kwa chilengedwe.

Methyl cellulose ndi ethel ether yokhala ndi zida zapadera zomwe zimathandizira mafakitale osiyanasiyana. Kusungunuka kwamadzi, kukhazikika kwamadzi, kukula, komanso katundu wopanga mafilimu omwe amawapatsanso mapulogalamu osiyanasiyana, kuphatikizapo chakudya, mankhwala opangira mankhwala, zodzoladzola komanso zodzola. Pomwe methyl cellulose imapereka zabwino zambiri, chilengedwe chake chiyenera kugwiritsidwa ntchito mosamala popanga zizolowezi zokhazikika komanso njira zomveka. Pafupifupi celyl cellulose imachita mbali yofunika kwambiri masiku ano, tsiku lililonse m'moyo watsiku ndi tsiku, zimathandizira kukulitsa zinthu zopangidwa ndi njira zatsopano.
