Kodi mungapange bwanji ethyl cellulose?

Ethyl cellulose ndi polima wopangidwa kuchokera ku cellulose, organic pawiri yomwe imapezeka muzomera. Ndi ufa woyera, wopanda fungo, wopanda kukoma womwe susungunuka m'madzi ndi zosungunulira zambiri za organic. Ethyl cellulose EC imagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza zokutira, zomatira, ndi mankhwala.

Njira yopanga ethyl cellulose imaphatikizapo njira zingapo. Choyamba ndi kupeza mapadi, omwe angapezeke ku zomera monga thonje, matabwa, kapena nsungwi. Ma cellulose amathandizidwa ndi asidi amphamvu, monga sulfuric acid, kuti aphwanyire cellulose kukhala zigawo zake za shuga. Mamolekyu a shuga amakhudzidwa ndi mowa wa ethyl kupanga ethyl cellulose.

Ethyl cellulose ndiye amayeretsedwa ndi njira yotchedwa fractional precipitation. Izi zimaphatikizapo kuwonjezera zosungunulira mu ethyl cellulose solution, zomwe zimapangitsa kuti cellulose ya ethyl itulukemo. The precipitated ethyl cellulose ndiye amasonkhanitsidwa ndikuwumitsa.

Njira yomaliza ndikusinthira cellulose yowuma ya ethyl kukhala ufa. Izi zimachitika pogaya cellulose ya ethyl kukhala ufa wabwino. Kenako ufawo ndi wokonzeka kugwiritsidwa ntchito zosiyanasiyana.

Ethyl cellulose ndi chinthu chosunthika chomwe chitha kugwiritsidwa ntchito mosiyanasiyana. Amagwiritsidwa ntchito popaka, zomatira, ndi mankhwala, ndipo amatha kupanga mafilimu, ulusi, ndi ma gels. Amagwiritsidwanso ntchito popanga utoto, inki, ndi zinthu zina. Ethyl cellulose imagwiritsidwanso ntchito ngati thickening muzakudya, komanso ngati stabilizer mu zodzoladzola.
