Methylcellulose (MC) ndi chochokera ku cellulose kudzera mu mankhwala a methylation ndipo ali ndi mawonekedwe apadera a thupi ndi mankhwala. Monga chowonjezera chogwiritsidwa ntchito kwambiri, chimagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana, kuphatikizapo zipangizo zomangira, chakudya, mankhwala, zodzoladzola ndi zokutira, ndi zina zotero. chinthu chofunikira pakuwongolera ndi kukulitsa mapangidwe amakampani.
1. Kunenepa kwambiri
Kukhuthala kwa methylcellulose kumapangitsa kuti ikhale chowonjezera chofunikira pamafakitale omanga ndi zokutira. M'makampani omangamanga, makamaka mumatope opangidwa ndi simenti ndi gypsum, methylcellulose imatha kukulitsa kugwirizana ndi kukhuthala kwa chilinganizo, potero kumapangitsa kuti zinthuzo zitheke. Kwa zokutira ndi utoto, kuwonjezera kwa methylcellulose kumatha kulepheretsa madzimadzi kukhala amadzimadzi kwambiri ndikuwonjezera kumamatira ndi kufananiza kwa zokutira.
Limagwirira wa thickening makamaka mwa mapangidwe maukonde dongosolo mu njira ndi methylcellulose. Unyolo wa mamolekyulu a methylcellulose amalumikizana kudzera mu zomangira za haidrojeni m'madzi kuti apange yankho ndi kukhuthala kwina. Izi maukonde dongosolo akhoza analanda ndi kukonza madzi mamolekyu, potero kuonjezera mamasukidwe akayendedwe ndi bata dongosolo madzi.
2. Kusunga madzi
Muzinthu zomangira monga matope a simenti ndi gypsum slurries, kusungirako madzi kwa methylcellulose ndikofunikira. Zipangizo zomangira zimafunikira chinyezi chokwanira kuti zichitepo kanthu pochiritsa. Kutaya madzi msanga kumabweretsa kusakwanira kwa mankhwala, kuchepa kwa mphamvu, kapena ming'alu pamtunda. Methylcellulose amapanga filimu yopyapyala pamwamba pa zinthuzo kuti ateteze kuphulika kwa madzi ndikuwonetsetsa kuti simenti, pulasitala ndi zinthu zina zimakhala ndi chinyezi chokwanira panthawi yochiritsa, potero zimawonjezera mphamvu ndi kulimba kwawo.
Kusunga madzi kumeneku kumakhala kofunikira makamaka m'malo owuma kapena otentha kwambiri, kulola methylcellulose kukhathamiritsa magwiridwe antchito a mafakitale pansi pazachilengedwe.
3. Kumanga ndi kukulitsa mphamvu zakuthupi
Zomwe zimagwirizanitsa za methylcellulose zimakhalanso zabwino kwambiri pakupanga mafakitale. Mwachitsanzo, mu zomatira za matailosi ndi mitundu ina ya zomangira zomangira, methylcellulose imatha kupititsa patsogolo kuphatikizika kwa mapangidwewo, kulola kuti zinthu zomangira zigwirizane bwino ndi ntchito. Maselo aatali a methylcellulose amatha kuyanjana ndi matrix kuti apititse patsogolo mphamvu yolumikizirana, motero kumapangitsa kuti zinthuzo zikhale zolimba.
M'mapulasitiki opangidwa ndi fiber-reinforced (FRP), methylcellulose imatha kulimbitsa mphamvu ndi kulimba kwa zinthu zophatikizika kudzera mu kapangidwe kake ka ulusi, kupangitsa kuti zinthuzo zikhale zolimba kwambiri komanso kukana kuvala, motero kumapangitsa kukhazikika kwake pamafakitale. kugonana.
4. Kupanga mafilimu
Methylcellulose ali ndi luso labwino lopanga filimu poyankha, ndipo katunduyu wakhala akugwiritsidwa ntchito kwambiri m'mafakitale ambiri. M'makampani opanga utoto ndi utoto, methylcellulose imatha kupanga filimu yoteteza yunifolomu yomwe imawonjezera kukana kwamadzi ndi kukana kwamankhwala kwa zokutira.
M'makampani azakudya, methylcellulose imagwiritsidwanso ntchito popaka kapena kupanga mafilimu, makamaka pakusunga mwatsopano zipatso, ndiwo zamasamba ndi zakudya zina. Popanga filimu yopyapyala, methylcellulose imachepetsa kutaya kwa chinyezi ndikuteteza chakudya ku chilengedwe chakunja.
5. Kukhazikika ndi emulsification
Methylcellulose imatha kutulutsa njira yowoneka bwino kwambiri ikasungunuka m'madzi, yomwe imakhala ndi kukhazikika komanso kutulutsa. Katunduyu ndi wofunikira makamaka m'mafakitale monga zokutira, utoto, zodzoladzola komanso zokonzekera zamankhwala. Mu utoto ndi utoto, methylcellulose imatha kukhazikika kufalikira kwa ma pigment, kuteteza kukhazikika, ndikuwongolera gloss ndi kufananiza kwa zokutira; mu zodzoladzola formulations, methylcellulose amagwira ntchito ngati emulsifier kukhazikika madzi-mafuta osakaniza dongosolo ndi kupewa Stratification zimachitika.
Pokonzekera mankhwala, methylcellulose nthawi zambiri amagwiritsidwa ntchito kulimbitsa ndi kukhazikika pakukonzekera kwamadzi amkamwa komanso ngati chonyamulira cha mankhwala. Kukhuthala kwake komanso kupanga filimu kungathandize kuti mankhwalawa atulutsidwe pang'onopang'ono, kuwonjezera nthawi ya mankhwala, komanso kusintha bioavailability wa mankhwalawa.
6. Thermal gelling katundu
Chinthu chofunika kwambiri cha methylcellulose ndi khalidwe lake lapadera la matenthedwe, momwe amasandulika gel akatenthedwa. Makhalidwe amenewa zimapangitsa Irreplaceable ena apadera mafakitale formulations. Mwachitsanzo, m'makampani azakudya, methylcellulose imagwiritsidwa ntchito popanga zakudya zopanda mafuta ochepa. Gel yomwe imapangidwa pambuyo pa kutentha imakhala ndi kukoma kofanana ndi mafuta, zomwe zimalola kuti zakudya zopanda mafuta zikhalebe bwino komanso zowoneka bwino. M'makampani omanga, malo otenthetsera a gelling awa amathandizira kukhazikika komanso kukhazikika kwa zida zomangira m'malo otentha kwambiri.
7. Biocompatibility ndi chilengedwe mwaubwenzi
Methylcellulose, monga gawo lochokera mwachilengedwe, ali ndi biocompatibility yabwino komanso kuyanjana ndi chilengedwe. Izi zimapangitsa kuti ikhale yotchuka kwambiri m'mafakitale amakono, makamaka m'madera omwe ali ndi zofunikira zotetezera zachilengedwe, monga nyumba zobiriwira, zokutira zachilengedwe ndi zipangizo zowonongeka. Methylcellulose imatha kunyonyotsoka mwachilengedwe, kuchepetsa kulemedwa kwa chilengedwe ndikugwirizana ndi zomwe zikuchitika m'mafakitale a chitukuko chokhazikika.
8. Kupititsa patsogolo kukonza bwino
Pakupanga mafakitale, methylcellulose imatha kusintha magwiridwe antchito. Mwachitsanzo, muzomangamanga, methylcellulose imatha kupititsa patsogolo madzi ndi kusunga madzi azinthu, potero kumapangitsa kuti zomangamanga zikhale zosavuta komanso zosavuta; mu zodzoladzola ndi kukonzekera mankhwala, methylcellulose akhoza kusintha kukhazikika kwa ma formula ndi kuchepetsa mpweya. ndi delamination, potero kuwonjezera alumali moyo wa mankhwala. Zinthu izi zimalola methylcellulose kuti ipititse patsogolo ntchito zopanga komanso kukhathamiritsa mapangidwe a mafakitale.
Monga chowonjezera chamagulu ambiri, methylcellulose imagwiritsidwa ntchito m'mafakitale ambiri monga zomangamanga, chakudya, mankhwala, zodzoladzola, zokutira, etc. chifukwa cha katundu wake wambiri monga thickening, kusunga madzi, kugwirizanitsa, kupanga mafilimu, kukhazikika, emulsification ndi gelling yotentha. amagwira ntchito yofunika kwambiri m'munda. Iwo sangakhoze kumapangitsanso thupi katundu wa formulations mafakitale, komanso kupititsa patsogolo kupanga Mwachangu ndi kukwaniritsa zosiyanasiyana mafakitale zofunika. Panthawi imodzimodziyo, biocompatibility ndi chilengedwe cha methylcellulose chimapangitsanso kukhala chinthu choyenera chomwe chimakwaniritsa zofunikira za chitukuko chokhazikika. Pogwiritsa ntchito moyenera methylcellulose m'mapangidwe a mafakitale, sizingangowonjezera ubwino wa mankhwala, komanso zimalimbikitsa kupita patsogolo ndi chitukuko cha luso la mafakitale.
