Nā hopena o ka wela ma ka mālama ʻana i ka wai o ka Cellulose Ether

Hiki ke hoʻopili ʻia nā waiwai paʻa wai o nā cellulose ethers, me ka carboxymethyl cellulose (CMC) a me ka hydroxyethyl cellulose (HEC), e ka wela. Eia nā hopena o ka wela ma ka paʻa ʻana o ka wai o nā cellulose ethers:

1. Viscosity: Ma nā mahana kiʻekiʻe, e emi ana ka viscosity o nā hoʻonā cellulose ether. I ka emi ʻana o ka viscosity, emi ka hiki o ka cellulose ether ke hana i kahi gel mānoanoa a mālama i ka wai. Hiki i kēia ke hoʻemi i nā waiwai paʻa wai ma nā mahana kiʻekiʻe.
2. Solubility: Hiki i ka wela ke hoʻopili i ka solubility o nā cellulose ethers i loko o ka wai. Hiki i kekahi mau cellulose ethers ke hoʻemi i ka solubility i nā mahana kiʻekiʻe, e alakaʻi ana i ka emi ʻana o ka mana paʻa wai. Eia naʻe, hiki ke ʻokoʻa ke ʻano solubility ma muli o ke ʻano kikoʻī a me ka pae o ka cellulose ether.
3. Ka Waiwai: Hiki i nā mahana kiʻekiʻe ke hoʻolalelale i ka hydration rate o cellulose ethers i loko o ka wai. Hiki i kēia ke hoʻonui mua i ka mana paʻa wai i ka wā e pehu ai ka cellulose ether a hana i kahi gel viscous. Eia nō naʻe, ʻo ka hoʻolōʻihi ʻia ʻana i nā mahana kiʻekiʻe e alakaʻi i ka hoʻohaʻahaʻa mua ʻana a i ʻole ka haki ʻana o ka hale gel, e hopena i ka paʻa ʻana o ka wai i ka manawa.
4. Evaporation: Hiki i nā wela kiʻekiʻe ke hoʻonui i ka nui o ka hoʻoheheʻe ʻana o ka wai mai ka cellulose ether solutions a i ʻole ka hui ʻana o ka mortar. Hiki i kēia evaporation wikiwiki ke hoʻopau i ka ʻike wai i loko o ka ʻōnaehana me ka wikiwiki, hiki ke hōʻemi i ka pono o nā mea hoʻohui paʻa wai e like me cellulose ethers.
5. Nā Kūlana Noi: Hiki i ka wela ke hoʻopili i nā kūlana noi a me nā ʻāpana hana o nā huahana cellulose ether. No ka laʻana, i loko o nā noi hana e like me nā tile adhesives a i ʻole nā ​​mortar sima, hiki i nā wela kiʻekiʻe ke hoʻolalelale i ka hoʻonohonoho ʻana a i ʻole ka hoʻoponopono ʻana, e pili ana i ka hana a me ka hana o ka mea.
6. ʻO ke kūpaʻa wela: Hōʻike maʻamau nā cellulose ethers i ke kūpaʻa wela maikaʻi ma luna o kahi ākea ākea. Eia nō naʻe, hiki ke hoʻohaʻahaʻa a hoʻoheheʻe ʻia nā kaulahao polymer no ka lōʻihi o ka loaʻa ʻana i nā wela wela, e alakaʻi ana i ka nalowale o nā waiwai paʻa wai. Pono nā kūlana mālama a mālama pono i ka mālama pono a me ka hana o nā cellulose ethers.

ʻoiai hiki i ka mahana ke hoʻopili i nā waiwai paʻa wai o cellulose ethers, ʻokoʻa paha nā hopena kikoʻī ma muli o nā kumu e like me ke ʻano o ka cellulose ether, ka hoʻonā hopena, ke ʻano noi, a me nā kūlana kaiapuni. He mea nui e noʻonoʻo i kēia mau mea i ka wā e hoʻokumu ai a hoʻohana paha i nā huahana cellulose ether-based e hōʻoia i ka hana maikaʻi loa ma lalo o nā kūlana wela.
