ʻO ka sodium carboxymethyl cellulose

ʻO ka sodium carboxymethyl cellulose (CMC-Na) kahi huaʻai carboxymethylated o ka cellulose a ʻo ia ka mea nui ionic cellulose gum. ʻO ka sodium carboxymethyl cellulose ka mea maʻamau he pūhui polymer anionic i hoʻomākaukau ʻia e ka hana ʻana i ka cellulose kūlohelohe me ka alkali caustic a me ka waikawa monochloroacetic, me ke kaumaha molekala mai nā tausani a i miliona. ʻO ka CMC-Na he fibrous keʻokeʻo a i ʻole ka pauka granular, ʻala ʻole, ʻono ʻole, hygroscopic, maʻalahi e hoʻopuehu i ka wai e hana i kahi hopena colloidal akaka.

2. Ka waiwai kino a me ke kemika

ʻO CMC-Na no ka pauka pōkole, keʻokeʻo a i ʻole melemele ʻeleʻele, mea granular a fibrous paha, ikaika hygroscopicity, hiki ke hoʻoheheʻe ʻia i ka wai, a ʻo ka hopena he wai viscosity kiʻekiʻe ke kū ʻole a alkaline paha. Paʻa i nā lāʻau lapaʻau, māmā a me ka wela. Eia naʻe, ua kaupalena ka wela i 80 ° C, a inā lōʻihi ka wela ma luna o 80 ° C, e emi ana ka viscosity a hiki ʻole ke hoʻoheheʻe ʻia i ka wai. He 1.60 kona mānoanoa pili, a he 1.59 ka mānoanoa pili o nā flakes. ʻO ka index refractive he 1.515. Huli ʻeleʻele i ka wā i wela ai i 190-205°C, a i carbonize i ka wā i wela ai i 235-248°C. ʻO kona hiki ke hoʻoheheʻe ʻia i ka wai ma muli o ke ʻano o ka hoʻololi ʻana. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka waikawa a me ka waiʻona, ʻaʻohe ua i ka paʻakai. ʻAʻole maʻalahi ka ferment, he mana emulsifying ikaika i ka ʻaila a me ka wax, a hiki ke mālama ʻia no ka manawa lōʻihi.

3. Ke noi nui

Hoʻohana nui ʻia i ka ʻoihana ʻaila e ʻeli ana i ka mea hoʻomaʻamaʻa lepo, ka mea hoʻomaʻemaʻe synthetic, ka mea hana mea hoʻomaʻemaʻe organik, ka paʻi lole a me ka dyeing sizing agent, ka wai-soluble colloidal tackifier no nā huahana kemika i kēlā me kēia lā, tackifier a me emulsifier no ka ʻoihana lāʻau, mānoanoa no ka ʻoihana meaʻai Thickener, adhesive no ka ceramic ʻoihana, pāpaʻi ʻoihana, mea hoʻonui nui no ka ʻoihana pepa, a me nā mea ʻē aʻe.

ʻO ka sodium carboxymethyl cellulose kekahi ʻano mānoanoa. Ma muli o kāna mau waiwai hana maikaʻi, ua hoʻohana nui ʻia i ka ʻoihana meaʻai, a ua hoʻolaha pū i ka hoʻomohala wikiwiki a me ke olakino o ka ʻoihana meaʻai i kekahi ʻano. No ka laʻana, ma muli o kona ʻano mānoanoa a me ka emulsifying hopena, hiki ke hoʻohana ʻia e hoʻopaʻa i nā inu yogurt a hoʻonui i ka viscosity o ka ʻōnaehana yogurt; ma muli o kāna mau waiwai hydrophilicity a me ka rehydration, hiki ke hoʻohana ʻia e hoʻomaikaʻi i ka ʻai ʻana i ka pasta e like me ka berena a me ka berena mahu. maikaʻi, hoʻolōʻihi i ke ola o nā huahana pasta, a hoʻomaikaʻi i ka ʻono; no ka mea, loaʻa iā ia kahi hopena gel, kūpono ia i ka hoʻokumu ʻana o ka gel i ka meaʻai, no laila hiki ke hoʻohana ʻia e hana i ka jelly a me ka jam; hiki ke hoʻohana ʻia e like me ke kiʻi ʻoniʻoni edible ua hoʻohui ʻia ka mea me nā mea mānoanoa ʻē aʻe a kau ʻia ma luna o ka ʻili o kekahi mau meaʻai, hiki ke mālama i ka meaʻai hou i ka nui loa, a no ka mea he mea ʻai ia, ʻaʻole ia e hoʻopilikia i ka ʻai. hopena i ke ola kanaka. No laila, hoʻohana nui ʻia ka meaʻai CMC-Na, ma ke ʻano he meaʻai meaʻai maikaʻi loa, i ka hana meaʻai i ka ʻoihana meaʻai.
