CMC papa seramika

CMC Sodium carboxymethyl cellulosehiki ke hoʻoheheʻe ʻia ka hopena me nā mea hoʻopili wai-soluble a me nā resins. Ke emi nei ka viscosity o ka solution CMC me ka piʻi ʻana o ka mahana, a e hoʻihoʻi hou ka viscosity ma hope o ka hoʻoilo. ʻO ka wai wai CMC he wai non-Newtonian me ka pseudoplasticity, a ke emi nei kona viscosity me ka piʻi ʻana o ka ikaika tangential, ʻo ia hoʻi, ʻoi aku ka maikaʻi o ka wai o ka hopena me ka piʻi ʻana o ka ikaika tangential. ʻO ka sodium carboxymethyl cellulose (CMC) solution he ʻano pūnaewele kū hoʻokahi, hiki ke kākoʻo maikaʻi i nā mea ʻē aʻe, no laila e hoʻopuehu ʻia ka ʻōnaehana holoʻokoʻa.

Hiki ke hoʻohana ʻia ka CMC grade ceramic i ke kino seramika, pulp glazing, a me ka glaze nani. Hoʻohana ʻia i ke kino seramika, he mea hoʻoikaika maikaʻi ia, hiki ke hoʻoikaika i ka moldability o ka lepo a me nā mea one, hoʻomaʻamaʻa i ke kino a hoʻonui i ka ikaika pelu o ke kino ʻōmaʻomaʻo.

Nā noi:

1. Hoʻohana ʻia i ka paʻi seramika glaze

Hiki ke hoʻoheheʻe maikaʻi ʻia ka CMC, ʻike ʻia ka hopena kiʻekiʻe a ʻaneʻane ʻaʻohe mea kūpono ʻole. Loaʻa iā ia ka dilution shear maikaʻi a me ka lubricity, hiki ke hoʻomaikaʻi nui i ka hiki ke paʻi a me ka hopena hope o ka paʻi ʻana i ka glaze. I kēia manawa, loaʻa i ka CMC ka mānoanoa maikaʻi, ka hoʻopuehu a me ka hopena paʻa i ka wā i hoʻopili ʻia i ka paʻi ceramic glaze:

* Rheology paʻi maikaʻi e hōʻoia i ka paʻi paʻi;

* Akaka ke ʻano paʻi a paʻa ke kala;

* ʻO ka maʻalahi o ka hopena, ka lubricity maikaʻi, ka hopena hoʻohana maikaʻi;

* Hiki ke hoʻoheheʻe ʻia i ka wai, aneane pau nā mea i hoʻoheheʻe ʻia, ʻaʻole ʻupena paʻa, ʻaʻole paʻa i ka ʻupena;

* He kiʻekiʻe ke aniani a me ke komo ʻana i ka ʻupena maikaʻi;

* ʻO ka dilution shear maikaʻi, hoʻomaikaʻi nui i ka hiki ke paʻi ʻia o ka paʻi glaze;

 

2. No ka hoʻohana ʻana i ka ceramic infiltration glaze

Embossing glaze loaʻa i ka nui o nā mea paʻakai hiki ke hoʻoheheʻe ʻia, a me ka acidic, embossing glaze CMC i ʻoi aku ka maikaʻi o ka waikawa a me ka paʻakai paʻakai paʻa, no laila ka embossing glaze i ka hoʻohana ʻana a me ke kaʻina hana e mālama ai i ka viscosity paʻa, e pale i ka loli o ka viscosity a pili. ka ʻokoʻa kala, hoʻomaikaʻi nui i ka paʻa o ka embossing glaze:

* Hiki ke hoʻoheheʻe maikaʻi, ʻaʻohe plug, permeability maikaʻi;

* Hoʻohālikelike maikaʻi me ka glaze, no laila e kūpaʻa ka pua glaze;

* ʻO ke kūpaʻa waika maikaʻi, ke kūpaʻa alkali, ka paʻakai paʻakai a me ke kūpaʻa, hiki ke mālama i ka viscosity o ka infiltration glaze paʻa;

* He maikaʻi ka hoʻokō ʻana o ka hoʻonā ʻana, a maikaʻi ke kūpaʻa viscosity, hiki ke pale i nā loli viscosity i ka ʻokoʻa kala.

 

3. Hoʻohana i loko o ke kino seramika

Loaʻa i ka CMC kahi hanana polymer linear kūʻokoʻa. Ke hoʻohui ʻia ʻo CMC i ka wai, ua hui pū ʻia kāna hui hydrophilic me ka wai e hana i kahi papa i hoʻoheheʻe ʻia, no laila e hoʻopuehu mālie ʻia nā molekala CMC i ka wai. Ke hilinaʻi nei nā polymers CMC i ka paʻa hydrogen a me ka ikaika van der Waals e hana i kahi ʻōnaehana pūnaewele, no laila e hōʻike ana i ka pili. Hiki ke hoʻohana ʻia ʻo CMC no ke kino embryo ceramic ma ke ʻano he excipient, plasticizer a me ka mea hoʻoikaika ikaika no ke kino embryo i ka ʻoihana seramika.

* ʻO ka liʻiliʻi liʻiliʻi, ʻike ʻia ka hoʻonui ʻana i ka ikaika o ka ʻōmaʻomaʻo;

* E hoʻomaikaʻi i ka wikiwiki o ka hana ʻōmaʻomaʻo, hoʻemi i ka hoʻohana ʻana i ka ikehu;

* ʻO ka nalowale maikaʻi o ke ahi, ʻaʻohe koena ma hope o ke ahi ʻana, ʻaʻole pili i ke kala ʻōmaʻomaʻo;

* Maʻalahi ka hana, pale i ka ʻōwili ʻana o ka glaze, nele i ka glaze a me nā hemahema ʻē aʻe;

* Me ka hopena anti-coagulation, hiki ke hoʻomaikaʻi i ka wai o ka glaze paste, maʻalahi e hoʻopuʻi i ka hana glaze;

* Ma ke ʻano he billet excipient, hoʻonui i ka plasticity o nā mea one, maʻalahi e hana i ke kino;

* ʻO ke kūpaʻa ʻana o ka mīkini ikaika, ʻoi aku ka liʻiliʻi o ke kaulahao molekala i ke kaʻina o ka wili pōleʻa a me ka hoʻoulu ʻana mechanical;

* Ma ke ʻano he mea hoʻoikaika billet, hoʻonui i ka ikaika kulou o ka billet ʻōmaʻomaʻo, hoʻomaikaʻi i ke kūpaʻa o ka billet, hoʻemi i ka helu pōʻino;

* ʻO ka hoʻokuʻu ikaika a me ka hoʻopuehu ʻana, hiki ke pale i nā mea waiwai maikaʻi ʻole a me nā ʻāpana pulp e hoʻonoho ai, i hoʻopuehu ʻia ka slurry;

* E hoʻoheheʻe ʻia ka wai i loko o ka billet, pale i ka maloʻo a me ka haki ʻana, ʻoi aku ka nui o ka hoʻohana ʻana i nā bilets papahele papahele nui a me nā bilets brick poni, ʻike ʻia ka hopena.

 

4. Hoʻohana i loko o ka ceramic glaze slurry

No ka CMC ka papa polyelectrolyte, ka mea i hoʻohana nui ʻia ma ke ʻano he binder a me ka hoʻokuʻu ʻana i ka slurry glaze. I ka CMC i loko o ka glaze slurry, ka wai e komo i loko o ka CMC plastik apana i loko, hydrophilic hui hui me ka wai, hana wai absorption hoʻonui, oiai ka micelle i ka hydration hoonui, loko waho hui me ka wai papa i hoʻokumu 'ia, micelle i ka wā mua hemo i loko. ʻO ka hopena pili, no ka nui, ka ʻano asymmetry, aci hui pū ʻia me ka wai i hoʻokumu ʻia i ka ʻōnaehana pūnaewele, nui ka nui, no laila, he ikaika adhesion ikaika:

* Ma lalo o ke ʻano o ka haʻahaʻa haʻahaʻa, hoʻoponopono pono i ka rheology o ka glaze paste, maʻalahi e hoʻopili i ka glaze;

* Hoʻomaikaʻi i ka hana hoʻopaʻa ʻana o ka blank glaze, hoʻomaikaʻi nui i ka ikaika glaze, pale i ka deglazing;

* ʻO ka maikaʻi o ka glaze kiʻekiʻe, ka paʻi paʻa paʻa, a hiki ke hōʻemi i ka pinhole ma ke aniani sintered;

* ʻO ka hoʻopuehu maikaʻi a me ka hana colloid pale, hiki ke hana i ka slurry glaze i kahi kūlana dispersion paʻa;

* Hoʻomaikaʻi maikaʻi i ka ʻili o ka aniani, pale i ka wai mai ka hoʻoheheʻe ʻana o ka glaze i ke kino, hoʻonui i ka maʻalahi o ka glaze;

* Hōʻalo i ka haki ʻana a me ka paʻi ʻana i ka haki ʻana ma muli o ka hāʻule ʻana o ka ikaika o ke kino ma hope o ke aniani.
