Methylcellulose

ʻO ka methyl cellulose, i hoʻopau ʻia ʻo MC, i ʻike ʻia hoʻi he cellulose methyl ether, he nonionic cellulose ether. Loaʻa iā ia ke ʻano o ke keʻokeʻo, ʻulaʻula melemele a ʻulaʻula paha ka pauka, granular a i ʻole fibrous, odorless, tasteless, non-toxic and non-irritating, hygroscopic.

Hiki ke hoʻoheheʻe ʻia ka Methylcellulose i loko o ka ʻakika acetic glacial, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, ether, acetone, a me ka chloroform. Loaʻa iā Methylcellulose nā waiwai gel thermal kūikawā. Ke hoʻoheheʻe ʻia i loko o ka wai wela ma luna o 50 ° C, hiki iā ia ke hoʻopuehu wikiwiki a pehu a hana i kahi gel. Ke hāʻule ka mahana o ka wai ma lalo o 50 ° C, e hoʻoheheʻe ʻia i loko o ka wai e hana i ka wai. Hiki i nā ʻano wai a me nā ʻano gel ke launa pū kekahi me kekahi.

ʻO ka hoʻomākaukau ʻana o ka methyl cellulose e hoʻohana i ka cellulose kūlohelohe e like me ka pulupulu pulupulu a me ka pulp lāʻau e like me nā mea maka, a mālama ʻia me ka alkali (e like me ka sodium hydroxide, etc.) e loaʻa ai ka cellulose alkali, a laila etherified me ka hoʻohui ʻana i ka methyl chloride. ʻO ka hopena ma kahi mahana, ma hope o ka holoi ʻana, neutralization, dehydration, maloʻo a me nā kaʻina hana ʻē aʻe, e like me ka maʻemaʻe o ka huahana a me ka ʻike loea, hiki ke hoʻokaʻawale ʻia ka methyl cellulose i ka methyl cellulose pharmaceutical grade, food grade methyl cellulose, general-purpose methyl cellulose a me nā huahana ʻē aʻe. .

Kū'ē ka Methylcellulose i nā waikawa a me nā alkalis, nā aila, ka wela, nā microorganisms a me ka māmā. Loaʻa iā ia ka mānoanoa maikaʻi, hana kiʻiʻoniʻoni, mālama wai, emulsifying, wetting, dispersing, a me nā waiwai adhesive.

Loaʻa i ka Methylcellulose ka nui o nā noi i lalo, mai nā uhi, nā inika, nā mea hoʻopili i nā textiles, ka paʻi ʻana a me ke kala ʻana i ka lāʻau lapaʻau a me ka hana meaʻai. Nui nā ʻoihana i nā koi noi no nā huahana a loaʻa kahi ākea ākea ākea. Ma hope o ka hoʻomohala mau ʻana i ka wā lōʻihi, ua hoʻokumu ʻia ka ʻoihana methyl cellulose o koʻu ʻāina i kahi pālākiō, a ʻoi aku ka maikaʻi o ka huahana huahana, akā pono e ʻoi aku ka maikaʻi ma ke ʻano o ka unahi a me ka hoʻomohala piha!
