Methylcellulose

Methyl cellulose, yofupikitsidwa ngati MC, yomwe imadziwikanso kuti cellulose methyl ether, ndi nonionic cellulose ether. Imakhala ndi mawonekedwe a ufa woyera, wachikasu kapena wotuwa wonyezimira, wonyezimira kapena wonyezimira, wopanda fungo, wopanda pake, wopanda poizoni komanso wosakwiyitsa, wa hygroscopic.

Methylcellulose amasungunuka mu glacial acetic acid, koma osasungunuka mu zosungunulira za organic monga ethanol, ether, acetone, ndi chloroform. Methylcellulose ali ndi mawonekedwe apadera a gel osakaniza. Ikasungunuka m'madzi otentha pamwamba pa 50 ° C, imatha Kumwaza Mofulumira ndikutupa kupanga gel osakaniza. Pamene kutentha kwa madzi kutsika pansi pa 50 ° C, amasungunuka m'madzi kuti apange njira yamadzimadzi. Mayankho amadzimadzi ndi mawonekedwe a gel amatha kulumikizana wina ndi mnzake.

Kukonzekera kwa methyl cellulose kumagwiritsa ntchito mapadi achilengedwe monga zamkati za thonje ndi zamkati zamatabwa monga zopangira, ndipo amathandizidwa ndi alkali (monga sodium hydroxide, etc.) kuti apeze alkali cellulose, kenako etherified powonjezera methyl kolorayidi. Zochita pa kutentha kwina, pambuyo kutsuka, neutralization, kutaya madzi m'thupi, kuyanika ndi njira zina, malinga ndi mankhwala chiyero ndi okhutira luso, methyl mapadi akhoza kugawidwa mu mankhwala kalasi methyl mapadi, chakudya kalasi methyl mapadi, ambiri cholinga methyl cellulose ndi zinthu zina. .

Methylcellulose imagonjetsedwa ndi asidi ndi alkalis, mafuta, kutentha, tizilombo toyambitsa matenda ndi kuwala. Ili ndi kukhuthala bwino, kupanga filimu, kusunga madzi, emulsifying, kunyowetsa, kufalitsa, ndi zomatira.

Methylcellulose ili ndi ntchito zambiri zotsika pansi, kuyambira zokutira, inki, zomatira ku nsalu, kusindikiza ndi utoto kupita kumankhwala ndi kukonza chakudya. Mafakitale ambiri ali ndi zofunikira zogwiritsira ntchito malonda ndipo ali ndi malo okulirapo. Pambuyo pa chitukuko chokhazikika chanthawi yayitali, makampani amtundu wa methyl cellulose mdziko langa apanga sikelo inayake, ndipo mtundu wazinthuzo umakhala wabwino kwambiri, koma uyenera kukhala wabwino kwambiri potengera kukula ndi chitukuko chonse!
