Hoʻohana i ka sodium carboxymethyl cellulose a me ka hydroxyethyl cellulose i nā huahana kemika i kēlā me kēia lā

ʻO Carboxymethylcellulose sodium (CMC-Na) he mea olaola, he carboxymethylated derivative o cellulose, a me ka mea nui loa 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.

Inā kū ʻole a alkaline paha, ʻo ka hoʻonā he wai viscosity kiʻekiʻe. Paʻa i nā lāʻau lapaʻau, māmā a me ka wela. Eia naʻe, palena ka wela i 80°C, a inā lōʻihi ka wela ma luna o 80°C, e emi ana ka viscosity a hiki ole ke hooheheeia i ka wai.

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 hoʻonui i ka ʻono.

No ka loaʻa ʻana o kekahi hopena gel, ʻoi aku ka maikaʻi o ka meaʻai e hana i kahi gel maikaʻi, no laila hiki ke hoʻohana ʻia e hana i ka jelly a me ka jam; hiki ke hoʻohana ʻia ma ke ʻano he mea uhi meaʻai, hui pū ʻia me nā mea mānoanoa ʻē aʻe, a hoʻolaha ʻia Ma kekahi mau ʻaoʻao meaʻai, hiki iā ia ke mālama i ka meaʻai i ka nui loa, a no ka mea he mea ʻai ia, ʻaʻole ia e hoʻopilikia i ke kanaka. olakino. 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.

ʻO ka Hydroxyethylcellulose (HEC), ka hoʻohālikelike kemika (C2H6O2)n, he melemele keʻokeʻo a māmā paha, ʻaʻala ʻole, ʻaʻohe mea ʻawaʻawa a paʻa paʻa, i haku ʻia me ka cellulose alkaline a me ka ethylene oxide (a i ʻole chlorohydrin) Hoʻomākaukau ʻia e ka etherification reaction, no ka non- ionic soluble cellulose ethers. No ka mea he waiwai maikaʻi ʻo HEC o ka mānoanoa, hoʻokuʻu, hoʻopuehu, emulsifying, hoʻopaʻa ʻana, hana kiʻiʻoniʻoni, pale i ka wai a hāʻawi i ka colloid pale.

Hiki ke hoʻoheheʻe ʻia i ka wai ma 20°C. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe maʻamau. Loaʻa iā ia nā hana o ka mānoanoa, hoʻopaneʻe, hoʻopaʻa, emulsifying, dispersing, a mālama i ka makū. Hiki ke hoʻomākaukau ʻia nā hoʻonā i nā pae viscosity like ʻole. Loaʻa i ka hoʻoheheʻe paʻakai maikaʻi loa no nā electrolytes.

Hoʻololi iki ka viscosity i ka laulā o ka waiwai PH 2-12, akā e emi ana ka viscosity ma mua o kēia pae.
