ʻO ka sodium carboxymethyl cellulose (CMC) he anionic, kaulahao pololei, wai-soluble cellulose ether, he derivative o ka cellulose maoli a me ka waikawa chloroacetic e ka hoʻololi kemika.Loaʻa i kāna ʻano wai nā hana o ka mānoanoa, hana kiʻiʻoniʻoni, hoʻopaʻa ʻana, mālama ʻana i ka wai, pale colloidal, emulsification a me ka hoʻokuʻu ʻana, a hiki ke hoʻohana ʻia e like me flocculant, chelating agent, emulsifier, thickener, wai paʻa wai, sizing agent, film forming material, etc. ., ka mea i hoʻohana nui ʻia i ka meaʻai, lāʻau lapaʻau, uila, pesticides, ʻili, plastics, paʻi, keramika, ʻoihana kemika i kēlā me kēia lā a me nā ʻano ʻē aʻe.

ʻO ka sodium carboxymethyl cellulose ka mea maʻamau he pauka paʻa, i kekahi manawa granular a fibrous paha, keʻokeʻo a ʻulaʻula paha i ka waihoʻoluʻu, ʻaʻohe ʻala kūikawā, he mea kemika macromolecular, ikaika ka wettability, hiki ke hoʻoheheʻe i ka wai, i loko o ka wai e hana i kahi hopena viscous me ke kiʻekiʻe. māliko.ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai maʻamau, e like me ka ethanol, etera, chloroform a me benzene, akā hiki ke hoʻoheheʻe ʻia i loko o ka wai, hoʻoheheʻe pololei ʻia i loko o ka wai he mea lohi, akā nui loa ka solubility, a he viscosity ka wai.ʻOi aku ka paʻa o ka paʻa paʻa, no ka mea, loaʻa iā ia kekahi wai absorption a me ka haʻahaʻa, ma kahi maloʻo, hiki ke mālama ʻia no ka manawa lōʻihi.

① Kaʻina hana

1. Keʻano o ka wai

ʻO ke kaʻina hana wai-lāhuhi kahi kaʻina hana mua i ka hoʻomākaukau ʻana o ka sodium carboxymethyl cellulose.Ma keia kaʻina hana, ka alkali cellulose a me ka etherifying mea hana i loko o ka wai hoʻonā i loaʻa manuahi oxygen ions ions, a me ka wai i hoʻohana 'ia ma ke ano o ka hopena i loko o ke kaʻina hana, me ka organic solvents.

2. Keʻano solvent

ʻO ke ʻano solvent ʻo ia ke ʻano solvent organik, ʻo ia ke kaʻina hana i kūkulu ʻia ma ke kumu o ke ʻano kaila wai e hoʻololi ai i ka wai me ka mea hoʻoheheʻe organik ma ke ʻano he ʻano hopena.He kaʻina hana o ka alkalization a me ka etherification o ka cellulose alkali a me ka waikawa monochloroacetic i loko o kahi mea hoʻoheheʻe organik.E like me ka nui o ka hopena, hiki ke hoʻokaʻawale ʻia i ke ʻano kneading a me ke ʻano slurry ʻauʻau.ʻOi aku ka nui o ka solvent organik i hoʻohana ʻia i ke ʻano pulping ma mua o ke ʻano o ka kneading, a ʻo ka nui o ka solvent organik i hoʻohana ʻia i ke ʻano kneading ʻo ia ka ratio o ke kaumaha o ka nui o ka cellulose, aʻo ka nui o ka solvent organik i hoʻohana ʻia. i loko o ka pulping ka lakene o ka leo kaumaha o ka cellulose nui.Ke hoʻomākaukau ʻia ka sodium carboxymethyl cellulose e ke ʻano slurry ʻauʻau, aia ka paʻa paʻa i loko o ka slurry a i ʻole ke kūlana hoʻokuʻu i loko o ka ʻōnaehana, no laila ua kapa ʻia ke ʻano o ka ʻauʻau slurry ʻo ke ʻano hoʻomaha.

3. Slurry ala

ʻO ke ala slurry ka ʻenehana hou loa e hana ai i ka sodium carboxymethyl cellulose.ʻAʻole hiki i ke ʻano slurry ke hana wale i ka sodium carboxymethyl cellulose maʻemaʻe kiʻekiʻe, akā hana pū kekahi i ka sodium carboxymethyl cellulose me ke kiʻekiʻe o ka hoʻololi ʻana a me ka hoʻololi like ʻana.ʻO ke kaʻina hana o ke ʻano slurry e like me kēia: ʻo ka pulupulu pulupulu i kāwili ʻia i ka pauka e hoʻouna ʻia i ka mīkini alkalizing vertical i hoʻolako ʻia me ka isopropyl alcohol, a hoʻohui ʻia ka hopena sodium hydroxide i ka wā e hui ʻia ai ka alkalized, a ʻo ka mahana alkalizing ma kahi o 20. ℃.Ma hope o ka alkalization, hoʻomoʻi ʻia ka mea i ka mīkini etherifying vertical, a hoʻohui ʻia ka waiʻona isopropyl o ka waikawa chloroacetic, a ʻo ka mahana etherifying e pili ana i 65 ℃.E like me ka hoʻohana pono ʻana o ka huahana a me nā koi o ka maikaʻi, hiki ke hoʻoponopono ʻia ka nui o ka alkalization, ka manawa alkalization, ka nui o ka etherifying agent a me ka manawa etherification a me nā kaʻina hana ʻē aʻe.

② Ka laulā noi

1. ʻAʻole ʻo CMC he mea hoʻopaʻa emulsifying maikaʻi a me ka mānoanoa i nā noi meaʻai, akā loaʻa nō hoʻi ka paʻa hau a me ka hoʻoheheʻe ʻana, a hiki ke hoʻomaikaʻi i ka ʻono o ka huahana a hoʻonui i ka manawa mālama.

2. I loko o ka detergent, hiki ke hoʻohana ʻia ka CMC ma ke ʻano he anti-fouling redeposition agent, ʻoi loa no ka hydrophobic synthetic fiber fabric anti-fouling redeposition effect, ʻoi aku ka maikaʻi ma mua o ka carboxymethyl fiber.

3. I ka aila wili hiki ke hoʻohana 'ia e pale aila Wells e like me mud stabilizer, ka wai hoʻopaʻa 'oihana, ka nui o kela a me keia aila luawai he 2 ~ 3t pāpaʻu Wells, hohonu Wells 5 ~ 6t.

4. Hoʻohana ʻia i loko o ka ʻoihana lole e like me ke ʻano nui, ka paʻi ʻana a me ka waihoʻoluʻu slurry mānoanoa, paʻi lole a me ka hoʻopau ʻoʻoleʻa.

5. Hoʻohana ʻia e like me ka uhi ʻana i ka anti-settling agent, emulsifier, dispersant, leveling agent, adhesive, hiki ke hana i ka ʻāpana paʻa o ka pena i hoʻokaʻawale ʻia i loko o ka solvent, no laila ʻaʻole i stratified ka pena no ka manawa lōʻihi, akā hoʻohana pū ʻia i ka putty. .

6. Ma keʻano he flocculant i ka weheʻana i nā ion calcium ma mua o ka sodium gluconate iʻoi aku ka maikaʻi, e like me ka hoʻololi cation, ka hiki ke hoʻololi i ka 1.6ml / g.

7. Ma ka 'oihana pepa i ho'ohana 'ia e like me ka pepa sizing agent, hiki ke ho'omaika'i nui i ka ikaika malo'o a me ka ikaika pulu o ka pepa a me ka aila kū'ē, ink absorption a me ka wai kū'ē.

8. Ma ke ʻano he hydrosol i nā mea hoʻonaninani, hoʻohana ʻia ma ke ʻano he mānoanoa i ka toothpaste, ʻo kona dosage ma kahi o 5%.
