ʻO ka sodium carboxymethyl cellulose (CMC) he mau hana koʻikoʻi i ka hana ʻana i nā seramika, ʻoi aku hoʻi i ka hoʻoili ʻana a me ka hana ʻana.Eia ke ʻano o ka hoʻohana ʻia ʻana o CMC i nā ʻano hana like ʻole o ka hana seramika:

1. Hoʻopili i loko o nā kino Ceramic: Hoʻohana maʻamau ʻia ʻo CMC ma ke ʻano he mea hoʻopaʻa i loko o nā kino seramika a i ʻole nā ​​​​mea hana ʻōmaʻomaʻo.Hoʻohui ʻia nā pauka seramika, e like me ka pālolo a i ʻole ka alumina, me ka wai a me ka CMC e hana i ka nui palaki e hiki ke hana ʻia a hoʻoheheʻe ʻia i nā ʻano makemake, e like me nā tile, nā pōhaku lepo, a i ʻole ka ipu lepo.Hana ʻo CMC ma ke ʻano he mea hoʻopaʻa manawaleʻa, e hoʻopaʻa pū ana i nā ʻāpana seramika i ka wā o ka hana ʻana a me ka hoʻomaloʻo ʻana.Hāʻawi ia i ka cohesiveness a me ka plasticity i ka nui seramika, e ʻae ai i ka maʻalahi o ka lawelawe ʻana a me ka hana ʻana i nā ʻano paʻakikī.
2. Plasticizer a me Rheology Modifier: Hoʻohana ʻo CMC ma ke ʻano he plasticizer a me ka rheology modifier i nā slurries seramika a i ʻole nā ​​​​pahue i hoʻohana ʻia no ka hoʻolei ʻana, ka hoʻolei ʻana, a i ʻole nā ​​​​kaʻina extrusion.Hoʻomaikaʻi ʻo CMC i nā waiwai kahe a me ka hana o nā hoʻokuʻu seramika, e hōʻemi ana i ka viscosity a me ka hoʻonui ʻana i ka wai.Hoʻomaʻamaʻa kēia i ka hoʻolei ʻana a i ʻole ka hana ʻana i nā seramika i loko o nā mold a make paha, e hōʻoia ana i ka hoʻopiha piha ʻana a me nā hemahema liʻiliʻi o nā huahana hope.Kāohi pū ʻo CMC i ka sedimentation a i ʻole ka hoʻopaʻa ʻana i nā ʻāpana seramika i ka hoʻokuʻu ʻana, mālama i ka paʻa a me ka homogeneity i ka wā o ka hana.
3. Deflocculant: I ka hana seramika, hana ʻo CMC ma ke ʻano he deflocculant e hoʻopuehu a hoʻopaʻa i nā ʻāpana seramika i nā hoʻokuʻu wai.Hoʻopili ʻia nā molekala CMC ma luna o ka ʻili o nā ʻāpana seramika, e hoʻohuli ana kekahi i kekahi a pale i ka agglomeration a i ʻole flocculation.Ke alakaʻi nei kēia i ka hoʻopuehu maikaʻi ʻana a me ka paʻa ʻana o ka hoʻokuʻu ʻana, e hiki ai i ka hāʻawi like ʻana o nā ʻāpana seramika i nā slurries a i ʻole nā ​​​​pahu hoʻolei.Hōʻike nā hoʻokuʻu deflocculated i ka wai ʻoi aku ka maikaʻi, hoʻemi ʻia ka viscosity, a me ka hoʻomaikaʻi ʻana i ka hana hoʻoheheʻe ʻana, e hopena ana i nā seramika kiʻekiʻe me nā microstructure like ʻole.
4. Binder Burnout Agent: I ka wā o ka puhi ʻana a i ʻole ka sintering ʻana i nā ʻōmaʻomaʻo ceramic, lawelawe ʻo CMC ma ke ʻano he mea hoʻopau puhi.Loaʻa ka CMC i ka hoʻoheheʻe wela a i ʻole ka pyrolysis i nā mahana kiʻekiʻe, e waiho ana i nā koena carbonaceous e hoʻomaʻamaʻa i ka wehe ʻana i nā mea hoʻopili organik mai nā kino seramika.ʻO kēia kaʻina hana, i ʻike ʻia ʻo ka binder burnout a i ʻole debinding, e hoʻopau i nā mea kūlohelohe mai nā seramika ʻōmaʻomaʻo, e pale ana i nā hemahema e like me ka haki ʻana, warping, a i ʻole porosity i ke kī ʻana.Hāʻawi pū nā koena CMC i ka hoʻokumu ʻana o ka pore a me ka hoʻomohala kinoea, e hāpai ana i ka densification a me ka hoʻohui ʻana o nā mea seramika i ka wā sintering.
5. Manaʻo Porosity: Hiki ke hoʻohana ʻia ka CMC e hoʻomalu i ka porosity a me ka microstructure o nā seramika ma o ka hoʻoulu ʻana i nā kinetics maloʻo a me ka hoʻohaʻahaʻa ʻana o ka ʻōmaʻomaʻo.Ma ka hoʻoponopono ʻana i ka neʻe ʻana o ka CMC i ka hoʻokuʻu ʻana i ka seramika, hiki i nā mea hana ke hoʻololi i ka nui o ka maloʻo a me ka emi ʻana o nā seramika ʻōmaʻomaʻo, e hoʻonui ana i ka hāʻawi ʻana i ka pore a me ka nui o nā huahana hope.Pono ka porosity hoʻomalu no ka loaʻa ʻana o nā waiwai mechanical, thermal, a me nā uila i makemake ʻia i nā seramika no nā noi kikoʻī, e like me nā membrane kānana, kākoʻo catalyst, a i ʻole ka insulation thermal.

ʻO ka sodium carboxymethyl cellulose (CMC) ka hana koʻikoʻi i ka hana ʻana i nā seramika ma o ka lawelawe ʻana ma ke ʻano he binder, plasticizer, deflocculant, binder burnout agent, a me porosity control agent.Hāʻawi kona mau waiwai nui i ka hana ʻana, hoʻohua, a me ka maikaʻi o nā seramika, e hiki ai ke hana i nā huahana ceramic kiʻekiʻe me nā waiwai i hoʻohālikelike ʻia no nā noi ʻoihana like ʻole.
