He cellulose ether anei ka carboxymethyl cellulose?

Hoʻomaka i ka Carboxymethyl Cellulose (CMC)

ʻO Carboxymethyl cellulose, i hoʻopau pinepine ʻia e like me CMC, he mea hoʻohana maʻamau o cellulose, he polymer kūlohelohe i loaʻa i loko o nā paia cell o nā mea kanu. Loaʻa ia ma o ka hoʻololi kemika o ka cellulose, ma ka hoʻokomo ʻana i nā hui carboxymethyl (-CH2-COOH) ma luna o ka iwi kuamoʻo cellulose.

Hoʻolālā a me nā waiwai

Mālama ʻo CMC i ke ʻano kumu o ka cellulose, ʻo ia ke kaulahao laina o nā molekole glucose i hoʻopili ʻia e nā paʻa β(1→4) glycosidic. Eia naʻe, ʻo ka hoʻokomo ʻana i nā hui carboxymethyl e hāʻawi i nā waiwai koʻikoʻi i CMC:

Hoʻoheheʻe wai: ʻAʻole like me ka cellulose maoli, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia ka CMC i ka wai wela a me ka wai anuanu ma muli o ke ʻano hydrophilic o nā hui carboxymethyl.

Mānoanoa Mānoanoa: ʻO ka CMC kahi mea mānoanoa kūpono, e hana ana i nā hopena viscous ma nā haʻahaʻa haʻahaʻa. He waiwai kēia waiwai i ka nui o nā noi, me nā meaʻai, nā lāʻau lapaʻau, a me nā huahana mālama pilikino.

Hiki ke hana kiʻiʻoniʻoni: Hiki i ka CMC ke hana i nā kiʻiʻoniʻoni ke waiho ʻia mai ka hopena, e hoʻohana pono ai i nā noi kahi e koi ʻia ai kahi kiʻiʻoniʻoni lahilahi a maʻalahi, e like me ka uhi a me nā adhesives.

Paʻa a me ka hoʻohālikelike: Paʻa ʻo CMC ma luna o kahi ākea o ka pH a me nā kūlana wela, e hoʻohālikelike ʻia me nā ʻano mea like ʻole a kūpono i nā noi like ʻole.

Nā noi

Loaʻa nā waiwai nui o CMC i ka noi ma nā ʻoihana he nui:

ʻOihana Meaʻai: Hoʻohana nui ʻia ʻo CMC ma ke ʻano he mānoanoa, stabilizer, a me ka emulsifier i nā huahana meaʻai e like me nā kīʻaha, nā lole, ice cream, a me nā mea bakena. Hoʻomaikaʻi ia i ke ʻano, ka waha, a me ka paʻa o ka papa.

ʻO nā lāʻau lapaʻau: I loko o nā hana lāʻau lapaʻau, lawelawe ʻo CMC ma ke ʻano he mea hoʻopaʻa, disintegrant, a me ka hoʻokuʻu hoʻokuʻu ʻia i nā papa a me nā capsules. ʻO kona hiki ke hana i nā gels paʻa e hoʻohana pono ai ia i nā ʻano kumuhana e like me nā ʻaila a me nā lotions.

Nā Huahana mālama pilikino: He mea maʻamau ka CMC i nā huahana mālama pilikino e like me ka toothpaste, shampoos, a me ka creams, kahi e hana ai ʻo ia he mānoanoa, stabilizer, a me ka mālama mau.

ʻOihana Pepa: Ma ka hana pepa, hoʻohana ʻia ʻo CMC ma ke ʻano he mea hoʻonui i ka ʻili e hoʻomaikaʻi i ka ikaika o ka pepa, ka maʻalahi, a me ka ʻae ʻana i ka inika. He mea kōkua hoʻi ia e hoʻopaʻa ai, e kōkua ana i ka hoʻopaʻa ʻana i nā ʻāpana maikaʻi a me nā mea hoʻopiha i ka pepa.

Textiles: Hoʻohana ʻia ʻo CMC i ka paʻi lole a me nā kaʻina hoʻoluʻu ma ke ʻano he mānoanoa a me ka rheology hoʻololi no ka paʻi ʻana i nā paʻi a me nā ʻauʻau wai.

ʻO ka ʻaila ʻaila: Ma ka ʻoihana ʻaila ʻaila, ua hoʻohui ʻia ʻo CMC i nā wai wili e hāʻawi i ka mana viscosity, hoʻemi ʻana i ka wai, a me ka lubrication o nā pahu drill.

Hoʻohana nui ʻia ka hoʻohana nui ʻana o ka carboxymethyl cellulose i kāna hui kūʻokoʻa o nā waiwai, e hiki ai ke hoʻohana ʻia ma nā ʻano ʻano like ʻole. ʻO kona biodegradability a me ka non-toxicity e hāʻawi hou aku i kona hoʻopiʻi ʻana ma ke ʻano he ʻano hoʻomau a me ke kaiapuni i nā polymers synthetic i nā noi he nui.

ʻO ka carboxymethyl cellulose he cellulose ether me ka nui o nā noi ma muli o kona hoʻoheheʻe wai, nā waiwai mānoanoa, kūpaʻa, a me ka launa pū me nā mea ʻē aʻe. ʻO kona koʻikoʻi e pili ana i nā ʻoihana, e lilo ia i mea waiwai i nā huahana a me nā kaʻina hana.
