Cellulosesua hoʻohana nui ʻia i nā mea sima, ʻoi aku hoʻi i nā morta maloʻo, ma muli o ko lākou paʻa wai maikaʻi a me nā hopena mānoanoa.No laila, nā waiwai a me ka hoʻokumu ʻana ocellulose etera i hoʻololi ʻia nā mea hana sima a me ka pilina ma waenacellulose etera a ua lilo mālie ka slurry sima i mea nui o ka nānā ʻana ma nā kahua o nā mea kūkulu hale a me nā ʻenekinia i nā makahiki i hala.Nui nā hopena noiʻi i loaʻa.I ka hui ʻana i ka holomua noiʻi ma ka home a me nā ʻāina ʻē, aia nō nā pilikia ma hope o ka noiʻi a me ka noi ʻanacellulose etera i hoʻololi ʻia nā mea hana sima:
1. He nui na ano ocelluloses.ʻOiaicelluloses hoʻohana ʻia i nā mea hana sima ua māhele ʻia i nā ʻano he nui e like me HEC, HEMC a me HPMC ma muli o ko lākou pae o ka hoʻololi.ʻO ke ʻano like ocellulosesloaʻa nā ʻokoʻa he nui i ka hoʻolālā molekala, ke kaumaha molekala, ke degere o ka hoʻololi ʻana a i ʻole ka mea pani.I kēia manawa, ʻo ka hapa nui o ka noiʻi ʻana ma ka home a ma waho e pili ana i hoʻokahi a i ʻolecelluloses.ʻO ke koho ocellulose ether i kaupalena 'ia i ko lakou mau kahua o ka noi.Nā hiʻohiʻona molecular structure ocelluloses ʻaʻole i hōʻike ʻia, a ʻaʻole i hōʻike ʻia ko lākou ʻelele.ʻO ka hopena ka hopena hikiʻole ke "hoʻololi hapa", a aia nā kū'ē a me nā hoʻopaʻapaʻa ma waena o nā hopena hōʻike.No laila, pono e hoʻopaʻa pono i ka hoʻokaʻawale ʻana a me nā ʻano hana a me nā mīkini o nā ʻano ʻano like ʻolecellulose etera nā mea gelling i hoʻololi ʻia.
2. Ua aʻo ʻia nā palapala e kū nei i ka hopena ocelluloses ma nā ʻano waiwai like ʻole o nā mea sima, a ua hana i kekahi loiloi o kona ʻano hana, akā ʻaʻole hiki ke hoʻoholo i ka pilina ma waena o ka molecular structure ocelluloses a me nā waiwai o ka slurry sima i hoʻololi ʻia.maʻamau, a aia nā ʻokoʻa ʻokoʻa i kā lākou mau hana.Mawaenacellulose etera- nā mea i hoʻololi ʻia i ka sima, he liʻiliʻi nā haʻawina e pili ana i nā mea me nā ʻano molekala like ʻole, ʻaʻole hiki ke wehewehe maoli i ke ʻano o ka hoʻokumu ʻana o nā waiwai like ʻole.cellulose etera- nā mea hoʻololi i hoʻololi ʻia i ka sima..ʻOiai ua ʻike kekahi mau palapalacelluloses me nā ʻano molekala like ʻole i nā hopena like ʻole i ka hydration o ka sima, ʻaʻole i wehewehe hou ʻia nā kumu kumu.
3.The mechanical o ka mana ocellulose etera e aʻo hou ʻia ana nā kinetics hydration cement.I kēia manawa, e pili ana i ka hana hydration lohi ocellulose etera, ʻoiai ua manaʻo ʻia ʻo adsorption ke kumu maoli o ka hydration lohi ocellulose etera, ʻike ʻia ʻoi aku ka ikaika o ka hiki adsorption ma waena o nā huahana hydration acellulose etera, ʻoi aku ka lōʻihi o ka hydration o ka sima.ʻO ka hana adsorption ma waenacelluloses a me nā huahana hydration sima, a me nā kumu o nā mana adsorption like ʻolecelluloses a me nā huahana hydration sima, ʻaʻole i aʻo hou ʻia.
4. Hōʻike nā palapala e kū neicelluloses hiki ke hoʻololi nui i ka hoʻolālā pore o nā mea hoʻokumu sima.Celluloses ua manaʻoʻiʻo ʻia hoʻi he ʻeleʻele a loaʻa ka hopena ea i nā slurries sima hou, ma laila e hoʻonui ai i ka porosity o nā slurries sima paʻakikī.Eia naʻe, ka mana ocelluloses ʻAʻole i kamaʻilio pinepine ʻia ke ʻano maʻamau a me ka hoʻokumu ʻana o ka puʻupuʻu pore sima.
5. ʻO nā waiwai Rheological kekahi mea nui o ka hoʻohana ʻana ocelluloses i nā mea hana sima.ʻO ka mea pōʻino, he liʻiliʻi nā haʻawina e pili ana i nā waiwai rheological ocellulose etera slurry sima i hoʻololi ʻia ma ka home a ma waho.
