Methylcellulose ndi madzi osungunuka a cellulose omwe amagwiritsidwa ntchito kwambiri muzakudya, mankhwala, zodzoladzola, zomangamanga ndi mafakitale. Lili ndi ntchito zosiyanasiyana monga thickening, emulsification, kusunga madzi, ndi kupanga mafilimu, koma ntchito yake imatsagananso ndi zofooka zina ndi zolephera.
1. Nkhani zosungunuka
Methylcellulose ndi chinthu chosungunuka m'madzi, koma kusungunuka kwake kumakhudzidwa kwambiri ndi kutentha. Nthawi zambiri, methylcellulose imasungunuka bwino m'madzi ozizira, ndikupanga yankho lomveka bwino la viscous. Komabe, kutentha kwa madzi kukakwera kufika pamlingo wina, kusungunuka kwa methylcellulose kudzachepa ndipo ngakhale gelation idzachitika. Izi zikutanthauza kuti kugwiritsa ntchito methylcellulose kungakhale kochepa pa ntchito zina zotentha kwambiri, monga kukonza zakudya kapena mafakitale.
2. Kusakwanira kwa asidi ndi alkali kukana
Methylcellulose imakhala yosakhazikika m'malo okhala acidic kwambiri kapena amchere. Pansi pa pH yoopsa, methylcellulose ikhoza kusokoneza kapena kusintha mankhwala, kutaya ntchito zake. Mwachitsanzo, kukhuthala kwa methylcellulose kumatha kuchepa kwambiri pansi pa mikhalidwe ya acidic, yomwe ndizovuta kwambiri pazogwiritsa ntchito pomwe kusasinthika kokhazikika kumafunikira, monga chakudya kapena mankhwala. Choncho, mphamvu ya methylcellulose ingakhudzidwe pamene kukhazikika kwa nthawi yaitali kumafunika kapena kugwiritsidwa ntchito pamalo omwe ali ndi pH yosakhazikika.
3. Kusawonongeka kwachilengedwe
Ngakhale kuti methylcellulose imatengedwa kuti ndi yochezeka ndi chilengedwe chifukwa imachokera ku cellulose yachilengedwe ndipo ilibe poizoni komanso yopanda vuto, kuwonongeka kwake sikoyenera. Chifukwa methylcellulose imasinthidwa mwamapangidwe, kuwonongeka kwake m'chilengedwe kumakhala kotsika kwambiri kuposa cellulose yachilengedwe. Izi zingapangitse kuti methylcellulose achulukidwe m'chilengedwe, makamaka ngati atagwiritsidwa ntchito mochuluka, zomwe zingakhudze chilengedwe.
4. Zochepa zamakina
Methylcellulose sachita bwino pazinthu zina zomwe zimafuna mphamvu zambiri kapena zida zapadera zamakina. Ngakhale zimatha kupanga mafilimu kapena kukulitsa mayankho, zidazi zimakhala ndi mphamvu zamakina ofooka, zolimba komanso zolimba. Mwachitsanzo, muzinthu zomangira kapena zokutira zogwira ntchito kwambiri, methylcellulose sangapereke mphamvu kapena kulimba kofunikira, ndikuchepetsa magwiridwe antchito ake.
5. Mtengo wapamwamba
Mtengo wopangira methylcellulose ndi wokwera kwambiri, makamaka chifukwa cha zovuta kupanga zomwe zimafunikira kusintha kwamankhwala a cellulose achilengedwe. Poyerekeza ndi zina zokhuthala kapena zomatira, monga wowuma, guar chingamu, ndi zina zotero, mtengo wa methylcellulose nthawi zambiri umakhala wokwera. Choncho, m'mafakitale kapena ntchito zotsika mtengo, methylcellulose sangakhale yotsika mtengo, makamaka pamene zipangizo zina zilipo.
6. Akhoza kuyambitsa ziwengo kwa anthu ena
Ngakhale methylcellulose nthawi zambiri imadziwika kuti ndi yotetezeka komanso yopanda poizoni, anthu ochepa amatha kukhala ndi zotsatira zosagwirizana nayo. Makamaka m'minda yamankhwala kapena zodzoladzola, methylcellulose imatha kuyambitsa kuyabwa pakhungu kapena zovuta zina. Izi ndizovuta zomwe zingachitike pazogwiritsa ntchito komanso kuvomereza kwazinthu. Chifukwa chake, kusamala ndikofunikira mukamagwiritsa ntchito methylcellulose m'magulu ena, ndipo kuyezetsa koyenera kumachitidwa.
7. Kugwirizana ndi zosakaniza zina
M'mapangidwe apawiri, methylcellulose imatha kukhala ndi zovuta zofananira ndi zosakaniza zina. Mwachitsanzo, imatha kuchitapo kanthu ndi mchere wina, zowonjezera kapena zosungunulira organic, zomwe zimapangitsa kusakhazikika kwa kapangidwe kake kapena kuchepa kwa magwiridwe antchito. Nkhani yogwirizanayi imalepheretsa kugwiritsa ntchito methylcellulose muzolemba zina zovuta. Kuphatikiza apo, methylcellulose imatha kuwonetsa kuyanjana koletsana ndi zokhuthala zina, zomwe zimasokoneza kapangidwe kake.
8. Zomverera mu ntchito
M'minda yazakudya ndi mankhwala, kugwiritsa ntchito methylcellulose kumatha kukhudza mphamvu zamtundu wa mankhwalawa. Ngakhale methylcellulose nthawi zambiri imakhala yosakoma komanso yopanda fungo, nthawi zina imatha kusintha kapangidwe kake kapena kamvekedwe ka mkamwa. Mwachitsanzo, methylcellulose ikhoza kupereka kusasinthika kosagwirizana ndi chilengedwe kapena kumamatira kwazakudya, zomwe sizingakwaniritse zomwe ogula amayembekezera. Kuphatikiza apo, kugwiritsa ntchito methylcellulose muzinthu zina zamadzimadzi kumatha kusokoneza kayendedwe kawo kapena mawonekedwe ake, zomwe zimasokoneza kuvomereza kwa ogula.
Monga zinthu zosunthika, methylcellulose imagwiritsidwa ntchito kwambiri m'magawo ambiri, koma zofooka zake ndi zoperewera sizinganyalanyazidwe. Methylcellulose ali ndi zofooka zina mwa mawu a solubility, asidi ndi alkali kukana, biodegradability, makina katundu, mtengo ndi ngakhale ndi zosakaniza zina. Kumvetsetsa ndi kuthana ndi zofooka izi ndizofunikira kwambiri pakuwongolera kugwiritsa ntchito methylcellulose pakugwiritsa ntchito bwino.
