Methylcellulose ndi chinthu chosunthika komanso chosunthika chomwe chimagwiritsidwa ntchito m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera.Chochokera ku polysaccharide ichi chochokera ku cellulose ndichotchuka chifukwa cha kuthekera kwake kuchita maudindo osiyanasiyana m'magawo osiyanasiyana.
Mankhwala a methylcellulose:
Methylcellulose amapangidwa kudzera mu etherification ya cellulose, polima wachilengedwe wopezeka m'makoma a cellulose.Ma cellulose amapangidwa ndi mayunitsi a shuga omwe amalumikizidwa ndi β-1,4-glycosidic bond.Njira ya etherification imaphatikizapo kusintha magulu a hydroxyl mu cellulose ndi magulu a methyl.Kusintha kwamankhwala kumeneku kumapangitsa kuti methylcellulose ikhale yapadera, ndikupangitsa kuti isungunuke m'madzi nthawi zina.
Digiri ya m'malo (DS) imayimira kuchuluka kwamagulu a hydroxyl osinthidwa ndi magulu a methyl pagawo lililonse la shuga mu unyolo wa cellulose, zomwe zimakhudza kusungunuka, kukhuthala komanso kupanga gel osakaniza a methylcellulose.Pamene DS ikuwonjezeka, kusungunuka m'madzi ndi kusinthasintha kwakukulu kwa pawiri kumawonjezeka.
Makhalidwe a methylcellulose:
Kusungunuka kwa Madzi: Chimodzi mwazifukwa zazikulu zomwe methylcellulose amagwiritsa ntchito kwambiri ndi kusungunuka kwake m'madzi.Imawonetsa khalidwe lapadera muzitsulo zamadzimadzi - kupanga gel omveka bwino ndi viscous pamene amasungunuka m'madzi ozizira.Katunduyu ndi wofunikira kwambiri pamagwiritsidwe ntchito kuyambira pazakudya mpaka pazamankhwala.
Thermal gelation: Methylcellulose amadutsa njira yosinthira kutengera kutentha.Mukatenthedwa, njira yamadzimadzi ya methylcellulose imapanga gel, ndipo ikazizira, gel osakaniza amabwerera ku yankho.Katunduyu ndi wofunika kwambiri pokonzekera ma gels ndi machitidwe oyendetsedwa operekera mankhwala.
Kuthekera kopanga mafilimu: Methylcellulose amapanga mafilimu omveka bwino komanso osinthika oyenera kugwiritsidwa ntchito pamakampani azakudya monga zokutira, zomatira ndi mafilimu odyedwa.Mafilimu opanga mafilimu amakhudzidwa ndi zinthu monga ndende, kutentha ndi kupezeka kwa zina zowonjezera.
Rheological properties: Methylcellulose amawonetsa kumeta ubweya wa ubweya, zomwe zikutanthauza kuti kukhuthala kwake kumachepa chifukwa cha kumeta ubweya wa ubweya.Katunduyu ndi wopindulitsa muzogwiritsa ntchito monga utoto pomwe ntchito yosavuta imafunikira ndipo zinthuzo zimafunika kuyambiranso kukhuthala kwake mukatha kugwiritsa ntchito.
Biocompatibility: Biocompatibility ya methylcellulose ndiyofunika kwambiri pazamankhwala ndi zamankhwala.Nthawi zambiri amaonedwa kuti ndi abwino kuti agwiritsidwe ntchito pokonzekera mankhwala chifukwa ndi opanda poizoni komanso osakwiyitsa.Izi zapangitsa kuti ziphatikizidwe muzinthu zosiyanasiyana za mankhwala, kuphatikizapo njira zothetsera ophthalmic ndi machitidwe oyendetsedwa operekera mankhwala osokoneza bongo.
Kugwiritsa ntchito methylcellulose:
makampani azakudya:
Thickening agent: Methylcellulose amagwiritsidwa ntchito ngati thickening agent mu zakudya monga sauces, dressings ndi soups chifukwa amatha kupereka mamasukidwe akayendedwe popanda kusintha kukoma kapena maonekedwe a chomaliza.
M'malo mwa mafuta: Pazakudya zopanda mafuta kapena zopanda mafuta, methylcellulose imatha kutsanzira kapangidwe ka mafuta ndi pakamwa, kukulitsa chidziwitso.
mankhwala:
Mapiritsi a Mapiritsi: Methylcellulose amagwiritsidwa ntchito ngati chomangira m'makampani opanga mankhwala kuti apititse patsogolo mgwirizano wa zosakaniza zamapiritsi ndikuwonetsetsa kuti mapiritsi amakhalabe osasunthika panthawi yopanga ndi kugwiritsidwa ntchito.
Ophthalmic Solutions: Kuwonekera kwa methylcellulose mu njira zamadzimadzi kumapangitsa kuti ikhale yoyenera kugwiritsa ntchito maso monga madontho a m'maso ndi ma lens.
Makampani omanga:
Simenti ndi Zowonjezera Zamatope: Methylcellulose amawonjezedwa ku simenti ndi matope kuti apititse patsogolo ntchito, kusunga madzi ndi kumamatira.Zimalepheretsa kuyanika mwachangu, zomwe zimapangitsa kuti zigwiritsidwe ntchito bwino komanso kuchiritsa.
Paints ndi Zopaka:
Thickeners ndi Stabilizers: Methylcellulose amagwiritsidwa ntchito ngati thickener ndi stabilizer mu madzi utoto utoto ndi zokutira kuthandiza kukwaniritsa kugwirizana koyenera ndi kupewa pigment kukhazikika.
Makampani opanga nsalu:
Sizing wothandizila: Pokonza nsalu, methylcellulose imagwiritsidwa ntchito ngati sing agent kuti ipititse patsogolo kusalala ndi mphamvu ya ulusi.Amapereka zokutira zoteteza panthawi yoluka ndipo amalepheretsa kusweka kwa ulusi.
Zosamalira munthu:
Zodzoladzola zodzoladzola: Methylcellulose imaphatikizidwa mu zodzoladzola monga zodzoladzola ndi mafuta odzola chifukwa cha emulsion yake yokhazikika komanso yowonjezera.
Makampani a Mafuta ndi Gasi:
Drilling Fluid Additive: Methylcellulose amagwiritsidwa ntchito pobowola madzi mumsika wamafuta ndi gasi kuti azitha kuwongolera kukhuthala komanso kutayika kwamadzimadzi kuti zitsimikizike kuti kubowola bwino.
Mapepala ndi kulongedza:
Chowonjezera Chophimba: Methylcellulose imagwiritsidwa ntchito ngati chowonjezera chopangira mapepala ndi zokutira zopangira kuti zisindikizidwe, kusalala kwa pamwamba ndi kukana madzi.
Chotsukira:
Ma Stabilizers mu Detergents: Methylcellulose ikhoza kuwonjezeredwa ku zotsukira zamadzimadzi monga stabilizer kuteteza kupatukana kwa gawo ndikuwongolera kukhazikika kwa mapangidwewo.
Ntchito za Biomedical:
Njira Zoperekera Mankhwala Osokoneza Bongo: Methylcellulose amagwiritsidwa ntchito popanga njira zoperekera mankhwala zoyendetsedwa bwino, ndipo katundu wake wa thermogelling amalola kumasulidwa kwa mankhwala pakapita nthawi.
Kusindikiza kwa 3D:
Zida zothandizira: Pakusindikiza kwa 3D, methylcellulose ingagwiritsidwe ntchito ngati chinthu chothandizira, chomwe chimatha kuchotsedwa mosavuta pambuyo pa kusindikiza chifukwa cha kusungunuka kwa madzi.
Methylcellulose ndi chinthu chabwino kwambiri komanso chosunthika chomwe chimagwiritsidwa ntchito m'mafakitale osiyanasiyana.Kuphatikizika kwake kwapadera kwa kusungunuka kwamadzi, kutentha kwa kutentha, luso lopanga mafilimu ndi biocompatibility kumapangitsa kukhala chinthu chofunika kwambiri pazakudya, mankhwala, zipangizo zomangira, utoto, nsalu, zinthu zosamalira munthu ndi zina.Pamene teknoloji ndi mafakitale zikupita patsogolo, kusinthasintha kwa methylcellulose kumatsimikizira kufunika kwake ndikupitirizabe kugwiritsidwa ntchito pokwaniritsa zosowa za mafakitale osiyanasiyana.
