Hoʻohana ʻo CMC i ka ʻoihana pena a me ka uhi

Pena ka sodium carboxymethyl celluloseua loaʻa ʻO ka mānoanoa maikaʻi, ka dispersity a me ke kūpaʻa, hiki iā ia ke hoʻomaikaʻi i ka viscosity a me ka rheology o nā uhi, no laila ua hoʻohana nui ʻia i nā ʻāpana like ʻole, nā latex coatings, nā wai i hoʻokumu ʻia i waho a me nā uhi o loko, ka hoʻolei ʻana a me nā mea ʻē aʻe.

ʻO ka hopena i kapa ʻia ʻo ia ka hiki ke hoʻopuehu ʻia ka pauka CMC a hoʻoheheʻe koke ʻia i loko o ka wai wai ma ka lumi wela, he ʻokoʻa ia mai ke ʻano maʻamau o ka CMC hoʻoheheʻe mālie (pono ke ʻano maʻamau o CMC ma kahi o 2-3 mau hola kiʻekiʻe- e hoʻoheheʻe ʻia ka wikiwiki). ʻAʻole hiki koke ka viscosity o ka carboxymethyl cellulose CMC i kona viscosity maoli me ka wikiwiki o ka pauka, a aia i loko o 10-15 mau minuke ma hope o ka hemo ʻana o ka viscosity, hiki i ka hoʻokumu ʻana o ka viscosity maoli ke hoʻokō i ka colloid. . Eia kekahi, ʻoi aku ka maikaʻi o ka colloid stability o CMC koke ma mua o ka CMC maʻamau me nā kikoʻī like.

Pono opena papa carboxymethyl cellulose:

A) ʻAʻole i hoʻopaʻa ʻia ka uhi a hiki ke mālama ʻia no ka manawa lōʻihi;

B) Hiki iā ia ke hāʻawi i nā huahana kūikawā wikiwiki no ka uhi ʻana i nā noi ma nā kahua kūikawā;

C) Hoʻoponopono maikaʻi i ka rheology o ka slurry glaze, hoʻomaʻamaʻa i ka noi glaze, a hana i ka slurry glaze i kahi kūlana hoʻopuehu paʻa;

D) Hoʻomaikaʻi maikaʻi i ka ikaika glaze a me ka maʻalahi e pale i ka deglazing;

E) E hōʻoia i ke kaʻina hana paʻi i ka hana ʻana i ka paʻi glaze, a maopopo a nani hoʻi nā hiʻohiʻona paʻi;

F) ʻAʻole e hoʻopaʻa ʻia i ke kaʻina paʻi ʻana i ka glaze, ʻoi aku ka maikaʻi o ka hoʻoheheʻe wai ʻana o ka CMC a ʻaneʻane ʻaʻohe mea hiki ke hoʻoheheʻe ʻia e like me nā haumia fiber;

ʻO kapena Ua hui pono ʻia ka carboxymethyl cellulose me ka wai a hoʻomākaukau ʻia i loko o kahi kāpili paʻi no ka hoʻohana ʻana ma hope. Papa i loko o ka hoʻonohonoho hoʻopili ʻana i ka carboxymethyl cellulose paste adhesive, ʻo ka mea mua me ka hui ʻana i nā mea kanu i loko o ka cylinder e hui pū i kahi nui o ka wai maʻemaʻe, ma ke ākea ma lalo o ke ʻano o ka mea hoʻoulu ʻia, ka pae o ka uhi ʻana o ka carboxymethyl cellulose me ka mālie a me ke kaulike i nā mea i loko o ka cylinder. , e hoʻoulu mau, e hana i ka pena carboxymethyl cellulose a me ka hui kiʻekiʻe o ka wai, hiki i ka carboxymethyl cellulose ke hoʻoheheʻe piha i ka pae uhi. Ke hoohehee penapapa ʻO ka carboxymethyl cellulose, ke kumu o ka pālahalaha ʻana, a me ka hoʻoulu mau ʻana, ʻo ke kumu "e pale aku i ka pena kala carboxymethyl fiber a me ka hui wai, agglomeration, agglomeration, hoʻemi i ka pilikia paʻa carboxymethyl cellulose solubility", a hoʻomaikaʻi i ka helu dissolution o ka pena kala carboxymethyl. cellulose. ʻAʻole kūlike ka manawa hoʻoulu ʻana a me ka papa kala carboxymethyl cellulose, ʻelua mau manaʻo, ʻoi aku ka pōkole o ka manawa hoʻoulu ʻana ma mua o ka pena kala carboxymethyl cellulose ka manawa hoʻopau piha, ʻo ka manawa i koi ʻia ma ke kūlana kikoʻī.
