Kodi kupanga methylcellulose ndi chiyani?

Methylcellulose ndi mtundu wa polima wopangidwa ndi cellulose womwe umagwiritsidwa ntchito mosiyanasiyana, kuphatikiza chakudya, mankhwala, ndi zodzola.Ndi ufa woyera, wopanda fungo, wopanda kukoma womwe umasungunuka m'madzi ozizira ndipo umapanga gel pamene watenthedwa.Amapangidwa pochiza cellulose ndi methyl chloride ndi sodium hydroxide.

Njira yopangira methylcellulose imaphatikizapo njira zingapo.Chinthu choyamba ndikupeza zopangira, zomwe nthawi zambiri zimakhala cellulose.Ma cellulose amatha kupezeka kuchokera kuzinthu zosiyanasiyana, monga zamkati zamatabwa, thonje, ndi ulusi wina wazomera.Ma cellulose amathandizidwa ndi methyl chloride ndi sodium hydroxide kupanga methylcellulose polima.

Chotsatira ndikuyeretsa methylcellulose.Izi zimachitika pochotsa zonyansa monga lignin, hemicellulose, ndi zinthu zina zomwe zingasokoneze zomwe zimafunikira za methylcellulose.Izi kawirikawiri zimachitika pochiza methylcellulose ndi asidi kapena alkali, kapena pogwiritsa ntchito njira yotchedwa fractionation.

Methylcellulose ikatsukidwa, imawumitsidwa ndikusinthidwa kukhala ufa.Ufa uwu umakhala wokonzeka kugwiritsidwa ntchito m'njira zosiyanasiyana.

Methylcellulose angagwiritsidwe ntchito ngati thickening wothandizira, emulsifier, stabilizer, kapena gelling wothandizira.Amagwiritsidwanso ntchito pazakudya monga ayisikilimu, mavalidwe a saladi, ndi sosi.Pazamankhwala, amagwiritsidwa ntchito ngati chomangira, choyimitsa, komanso zokutira piritsi.Mu zodzoladzola, amagwiritsidwa ntchito ngati thickener, emulsifier, ndi stabilizer.

Njira yopangira methylcellulose ndiyosavuta komanso yothandiza.Ndi njira yotsika mtengo yopangira zinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito mosiyanasiyana.Ndizinthu zotetezeka komanso zopanda poizoni zomwe zingagwiritsidwe ntchito pazinthu zosiyanasiyana.
