ʻEtila kelulosa (EC)he ʻetera cellulose nonionic i loaʻa mai ka cellulose kūlohelohe ma o kahi hopena ethylation. Ma muli o kona mau waiwai hana kiʻiʻoniʻoni maikaʻi loa, kūpaʻa wela, a me ka inertness kemika, hoʻohana nui ʻia ia i nā uhi, nā inika, nā lāʻau lapaʻau, nā mea uila, a me nā ʻoihana ʻē aʻe. Eia nō naʻe, ʻo ka ethyl cellulose kuʻuna i hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e hōʻike ana i nā pilikia e like me ka flammability, nā hopohopo kaiapuni, a me nā kumukūʻai hana kiʻekiʻe. No ka hoʻoponopono ʻana i kēia mau pilikia, ua hoʻomohala ʻia nā aqueous ethyl cellulose dispersions (AECDs).
1. Ka wehewehe ʻana a me nā ʻano o nā Aqueous Ethyl Cellulose Dispersions
ʻO nā mea hoʻolaha aqueous ethyl cellulose he mau mea ia e hana i kahi hoʻolaha paʻa i ka wai me ka hoʻohana ʻana i ka emulsification, dispersion, a i ʻole nā ʻano hana hoʻololi. ʻO kā lākou mau hiʻohiʻona koʻikoʻi:
Hoʻokumu ʻia i ka wai a me ke aloha kaiapuni: Hōʻalo lākou i ka hoʻohana ʻana i nā mea hoʻoheheʻe organik kuʻuna, e hoʻokō ana i nā koi o nā uhi ʻoluʻolu kaiapuni hou a me nā ʻoihana kemika ʻōmaʻomaʻo.
Paʻa kiʻekiʻe: Hoʻopuehu like ʻia nā ʻāpana ethyl cellulose i loko o ka dispersion i loko o ka pae wai, e hōʻike ana i ke kūpaʻa mālama maikaʻi loa a kūʻē i ka sedimentation a i ʻole ka aggregation.
ʻO ka Viscosity hiki ke hoʻokele ʻia: Ma ka hoʻoponopono ʻana i ke kekelē o ka pani ʻana, ke kaumaha molekala, a me ka hoʻohuihui dispersant o ka ethyl cellulose, hiki ke loaʻa nā dispersions aqueous me nā viscosities like ʻole e hoʻokō ai i nā koi hana like ʻole.
Nā Waiwai Hoʻokumu ʻAiʻoniʻoni Maikaʻi Loa: Ma hope o ka mahu ʻana o ka wai i ka wā o ke kaʻina hana maloʻo, hana ka ethyl cellulose i kahi ʻaʻahu like a hoʻomau me ka ikaika mechanical maikaʻi loa a me ke kūpaʻa kemika.
Hoʻohālikelike ikaika: Hiki ke kāwili ʻia me nā ʻano mea hoʻohui like ʻole, nā resins, nā pigments, a me nā mea hoʻopihapiha, e kūpono loa ia no ka hoʻohana ʻana i nā pena, nā inika, a me nā uhi hana.
2. Nā ʻAno Hoʻomākaukau
2.1. Ke ʻano hoʻopuehu emulsion
Hoʻoheheʻe ʻia ka Ethyl cellulose i loko o kahi mea hoʻoheheʻe organik a laila, me ka hoʻohana ʻana i kahi emulsifier a me ka hoʻoulu wikiwiki ʻana, hana i kahi emulsion dispersion i loko o ka wai. A laila wehe ʻia ka mea hoʻoheheʻe organik e loaʻa ai kahi dispersion ethyl cellulose aqueous. Hoʻopuka kēia ʻano hana i kahi dispersion me ka liʻiliʻi o ka nui o nā ʻāpana a me ke kūpaʻa maikaʻi loa.
2.2. Ke ʻAno Hoʻopuehu Mekanika
Hoʻopuehu pololei ʻia ka pauka Ethyl cellulose i loko o kahi pae wai ma o ka ʻokiʻoki wikiwiki a i ʻole ka wili ʻana. A laila hoʻohui ʻia kahi mea hoʻolaha a mea hoʻomānoanoa paha e hoʻopaʻa i ka ʻōnaehana. He kūpono kēia ʻano hana no ka hoʻomākaukau ʻana i nā mea hoʻopuehu wai haʻahaʻa-viscosity.
2.3. Ke ʻAno Hoʻololi Kemika
Hoʻololi ʻia ka Ethyl cellulose me ke kemika ma o ka carboxylation hapa a i ʻole hydroxylation e hāʻawi i nā hui hydrophilic ma luna o kona ʻili, e ʻae ana iā ia e hana kūlohelohe i kahi dispersion paʻa i ka wai. Hoʻohana pinepine ʻia kēia ʻano hana i nā uhi hana a i ʻole nā ʻano lāʻau lapaʻau.
3. Nā noi o nā Ethyl Cellulose Aqueous Dispersions
3.1. Nā Uhi Wai
Ma ke ʻano he mau mea hoʻomānoanoa, nā mea kōkua hana kiʻiʻoniʻoni, a i ʻole nā mea hoʻopaʻa, hiki i nā ethyl cellulose aqueous dispersions ke hoʻomaikaʻi i ka laumania o ka uhi, ka hoʻopili ʻana, a me ke kūpaʻa i ka abrasion me ka hōʻemi ʻana i ka hoʻohana ʻana i nā solvents organik a me ka hoʻomaikaʻi ʻana i ka hana kaiapuni.
3.2. Nā ʻīnika wai
I loko o nā ʻīnika paʻi, hiki i nā ethyl cellulose aqueous dispersions ke hoʻomaikaʻi i ka pae ʻana a me ke ʻano like o ke kala, me ka hoʻomaikaʻi pū ʻana i ka wikiwiki o ka maloʻo ʻana a me ke kūpaʻa ʻana i ka wai. He kūpono lākou no ka paʻi ʻana i nā ʻōpala, ka paʻi flexographic, a me nā noi ʻē aʻe.
3.3. Nā lāʻau lapaʻau a me ka meaʻai
Ma ke ʻano he mau membrane hoʻokuʻu lāʻau lapaʻau a i ʻole nā uhi meaʻai, pale aku nā hoʻolaha ethyl cellulose aqueous i nā pilikia palekana o nā mea hoʻoheheʻe organik koena ʻoiai e hiki ai ke hoʻokuʻu i nā lāʻau lapaʻau i kāohi ʻia.
3.4. Nā Mea Uila a me nā Uhi Hana
I loko o nā mea hoʻopili uila a me nā kiʻiʻoniʻoni hana, hiki i nā ethyl cellulose aqueous dispersions ke lawelawe ma ke ʻano he matrices hana kiʻiʻoniʻoni, e hāʻawi ana i nā waiwai mechanical maikaʻi loa a me ke kūpaʻa wela. Hoʻohui maʻalahi ʻia lākou me nā nanomaterials e hana i nā kiʻiʻoniʻoni moakaka a alakaʻi paha.
4. Nā Mālama a me nā ʻAno Hoʻomohala
Ka Mana Paʻa: Hiki i nā hoʻopuehu wai ke maʻalahi i ka mahana, ka pH, a me nā electrolytes. No laila, pono e koho ʻia nā mea hoʻopuehu kūpono a me nā kūlana mālama e pili ana i ka hoʻohana kikoʻī.
Hana Hoʻomaloʻo ʻAna i ka Hana ʻAna i ka ʻIliʻili: ʻO ka mahu nui ʻana o ka wai e hiki ai ke nahā i ka uhi. Pono e hoʻomaikaʻi ʻia ke ʻano o ka uhi ʻana ma o nā mea hoʻohui a i ʻole ka hoʻomaikaʻi ʻana i ke kaʻina hana.
ʻŌmaʻomaʻo a me ka Hana Kiʻekiʻe: I ka wā e hiki mai ana, e hoʻomohala ʻia nā ʻano hoʻolaha wai ethyl cellulose i ka nui o nā mea paʻa, nā VOC haʻahaʻa, a me ka hana (e like me ke kāohi ahi, ke kūpaʻa wai, a me ka conductivity uila) e hoʻokō i nā pono ʻoihana a me nā lāʻau lapaʻau kiʻekiʻe.
Nā cellulose ʻEtilaʻO nā mea hoʻopuehu wai he mau mea hana wai kiʻekiʻe e pili ana i ke kaiapuni e hoʻohui i nā waiwai hana kiʻiʻoniʻoni maikaʻi loa o ka ethyl cellulose me nā pono ʻōmaʻomaʻo o nā ʻōnaehana wai. ʻAʻole wale lākou he mea pono i nā ʻoihana kuʻuna e like me nā uhi, nā ʻīnika, a me nā lāʻau lapaʻau, akā hōʻike pū kekahi i ka hiki i nā kahua e kū mai ana e like me nā mea uila a me nā uhi hana. Me ka hoʻolaha ʻana o nā manaʻo kemika ʻōmaʻomaʻo a me ka holomua o ka ʻenehana mea wai, e lilo ka hoʻopuehu wai ethyl cellulose i kuhikuhi hoʻomohala koʻikoʻi i ke kahua mea e hiki mai ana.
