He aha nā pōmaikaʻi o ka cellulose?

ʻO ka cellulose kahi ʻano cellulose e piʻi wikiwiki ana ka hana a me ka hoʻohana ʻana. He cellulose non-inorganic hui ʻia ether i hana ʻia mai ka pulupulu hoʻomaʻemaʻe ma hope o ka make ʻana, me ka hoʻohana ʻana i ka propylene oxide a me ka methyl chloride ma ke ʻano he etherification agents, a ma o ke ʻano o nā hopena. ʻO ka pae o ka hoʻololi ʻana he 1.2-2.0. ʻOkoʻa kona mau hiʻohiʻona ma muli o nā ʻano like ʻole o nā ʻāpana tert-butyl a me nā ʻāpana hydroxypropyl.

(1) Hiki ke hoʻoheheʻe ʻia ka cellulose i ka wai anuanu, a paʻakikī ke hoʻoheheʻe ʻia i ka wai paila. Akā ʻoi aku ka kiʻekiʻe o ka mahana o ka gelatinization i ka wai paila ma mua o ka carboxycellulose. ʻOi aku ka maikaʻi o ka hoʻoheheʻe ʻana i ka wai anuanu i ka hoʻohālikelike ʻia me ka carboxycellulose.

(2) Ua pili ka viscosity o ka cellulose i ka nui o ka molecular molecular mass, a me ka nui o ka molecular mass, ʻoi aku ka kiʻekiʻe o ka viscosity. E pili ana ka mahana i kona viscosity, piʻi ka mahana, emi ka viscosity. Akā ʻoi aku ka maikaʻi o kona viscosity kiʻekiʻe a me ka wela kiʻekiʻe ma mua o ka carboxycellulose. Paʻa kona ʻoluʻolu wai ke mālama ʻia ma ka mahana wela.

(3) Aia ka wai paʻa a me ka solubility o cellulose i kona nui hoʻohui, viscosity, etc., a ʻoi aku ka kiʻekiʻe o ka paʻa wai ma lalo o ka nui o ka hoʻohui ʻana ma mua o ka carboxycellulose.

(4) He kūpaʻa ʻo Cellulose i ka waikawa a me ka alkali, a paʻa loa kona hopena i ka pae o ka pH = 2 ~ 12. ʻAʻohe mana nui o ka alumini chloride a me ka lime slurry i kāna mau waiwai, akā hiki i ka alkali ke hoʻolōʻihi i kona helu hoʻoheheʻe a hoʻomaikaʻi i kona viscosity. Hiki ke hilinaʻi ʻia ka cellulose i nā paʻakai ʻakika maʻamau, akā ke kiʻekiʻe ka neʻe ʻana o ka hopena paʻakai, piʻi ka viscosity o ka solution cellulose.

(5) Hiki ke hoʻohana ʻia ka cellulose me nā polymers hiki ke hoʻoheheʻe ʻia i ka wai e hana i kahi ʻano like ʻole a kiʻekiʻe-viscosity aqueous solution. E like me ka acrylic emulsion, tapioca starch ether, mea kanu glue, etc.

(6) He ʻoi aku ka ikaika o ka pale ʻana i ka enzyme ma mua o ka carboxycellulose, a ʻoi aku ka liʻiliʻi o ka hoʻoheheʻe ʻia ʻana o ka wai e nā enzymes ma mua o ka carboxycellulose.

(7) ʻOi aku ka kiʻekiʻe o ka hoʻopili ʻana o ka cellulose i ke kūkulu ʻana i ka momi sima ma mua o ka carboxycellulose.
