?O Sodium Carboxyl methyl Cellulose (Carboxyl methyl Cellulose), i kapa ?ia ?o CMC, he cellulose ether, carboxyl methyl derivative o cellulose, ?ike ?ia ho?i he cellulose gum, ?o ia ka mea nui ionic cellulose gum. Ua hana ?ia ma ?Eulopa i nā makahiki 1910 mua a ua ho?ohana ?ia ma ke ?ano he colloid a me ka mea ho?opili. I ka makahiki 1947, ua ?ae ?ia e ho?ohana ?ia ma ke ?ano he mea ho?ohui i ka ?oihana hana mea?ai a he hopena mānoanoa. ?O ka wai wai o ka sodium carboxymethyl cellulose nā hana o ka mānoanoa, ka ho?opa?a ?ana, ka ho?okumu ?ana i ke ki?i?oni?oni, ka ho?opili pale, ka pa?a ?ana o ka wai, ka emulsification a me ka ho?oku?u ?ana, a me nā mea ?ē a?e. Ma waena o lākou, ua ho?ohana ?ia ka CMC pākaukau ma ke ?ano he mea ho?opa?a no nā pā uila uila lithium, a ua ulu wikiwiki ka makemake o ka mākeke i nā makahiki i hala me ka pi?i ?ana o ka ?oihana ka?a ka?a hou.

?enehana hana

?O ke ka?ina hana o ka sodium carboxymethyl cellulose e pili ana i ke ?ano o ka wai, ke ?ano ha?aha?a ha?aha?a, ke ?ano slurry (ke ?ano solvent lehulehu) a pēlā aku. ?O nā mea kī nui i ho?oma?ema?e ?ia i ka cellulose, a ?o ka ?oko?a ma waena o ke ?ano aqueous a me nā mea hope ?elua ?o ia "?a?ohe mea ho?ohehe?e organik e like me ka wai?ona ma ke ?ano he ?ano hopena i ke ka?ina o ka alkalization a me ka etherification". ?A?ole ki?eki?e ka paepae ?enehana o ke ?ano wai, akā ?a?ole ki?eki?e ka ma?ema?e a me ka ho?ololi ?ana o nā huahana i hana ?ia, a hiki ke ho?opili wale ?ia i ke kahua noi ha?aha?a. ?O nā huahana ma?ema?e ki?eki?e e pono e ho?oma?ema?e ?ia, ?o CMC i ho?oma?ema?e ?ia he pale ki?eki?e - ?oi aku ka maika?i o ka ho?opukapuka ?ana o nā lako hana a me ka ho?onui ?ana i ke ka?ina hana e ho?onui nui i ke kumukū?ai, ?o ke ?ano slurry kahi ka?ina holomua.

Kūlana ?oihana

?O ka ho?olaha ?ana o CMC ma kahi o ho?okahi haneli mau makahiki, ?oi loa ka ?enehana ka?ina hana a ?a?ohe hanana nui no nā makahiki he nui, no nā huahana kemika ma?amau, ?a?ole no ka nānā ?ana o nā ?oihana kemika nui, ?o ka hana ?ana o nā ?oihana ?ē a?e o CMC i kēia manawa he Herklex (Ashland), ho?okūkū Lu, pepa Iapana a pēlā aku. Ua komo ka ?oihana CMC kūloko i ke ala wikiwiki o ka ho?omohala ?ana ma hope o 1998. ?O ka mea nui, i ka ho?omaka ?ana o ke kenekulia 21, ua ulu ka noi no ka sodium carboxymethyl cellulose i loko o nā mākeke kūloko a me ka honua, a ?o ka awelika o ka ulu ?ana o ka makahiki CMC ma waena o 2006 a me 2010 ua hō?ea i 17%, kahi i ho?oulu ai i nā ka?ina hana sodium a me nā mea hana ma?alahi. ma ka piko, ua like loa ka lakou hana. ?O ka ?oko?a ma waena o nā ?oihana ?o ia ka ho?olako pa?a ?ana o nā kumu waiwai maka?u, nā kumukū?ai hana ?olu?olu a me ka maika?i o ka huahana.

Mai ka hi?ohi?ona o ka manawa komo ?oihana, ho?omaka ke komo ?ana o ka ?oihana ma 1998, ho?omau a hiki i 2016, a hiki i kahi ki?eki?e ma 2014. Ma waena o lākou, ?o 2001-2009 ka manawa gula o ka ho?omohala ?ana i ka ?oihana CMC kūloko, ho?omau ?ia nā ?oihana hou, ua komo nā ?oihana haole. Mai 2010 a 2016, ke ho?ololi nei ka wikiwiki a me ka helu o nā ?oihana, me ka manawa ?ole o ka ho?opukapuka kālā a me kahi ki?eki?e o ka ho?opukapuka kālā ma 2014. I ka makahiki 2016, ?oiai ua pi?i mau ka nui o ka lawe ?ana aku i ka home o carboxymethyl cellulose a me kāna mau huahana pa?akai, ua hā?ule ke kumu kū?ai kū?ai aku i kahi ha?aha?a ha?aha?a. Ma hope o ka makahiki 2017, ua malo?o nui ka ho?okomo ?ana i ka ?oihana CMC kūloko, me ?elua mau ?oihana hou. ?Oi aku ka ho?okūkū o kā lākou ?enehana a me nā huahana. No ka la?ana, ua ho?okumu ?ia ?o Hebi Fangrui Chemical ma o ka lawe ?ana i ka DuPont Danisco (Zhangjiagang) hydrophilic colloid hui lako a me nā ?enehana pili a me nā limahana hana. ?O Fujian Meiyarui New Materials Company wale nō ka hana ?ana i nā huahana cellulose ether, no nā pākahi lithium Ningde manawa e hana i nā mea kāko?o.
