Nā hopena o ka hoʻohana pono ʻole ʻana o Hydroxypropyl Methyl Cellulose

E pili ana i ke ʻano noi noi ʻoihana i hoʻohana ʻia e nā huahana kemika, pono ia e huki i ka nānā a me ka nānā ʻana o kēlā me kēia mea hana hana, no ka mea ʻo ia ke kī i ka hoʻoholo maikaʻi ʻana a me ka hoʻopau ʻana o kēlā me kēia papahana kūkulu. Inā pili nui ke ʻano o ka hana ʻana i ka hoʻohana palekana ʻana i ka huahana, no ka laʻana, hydroxypropyl methylcellulose, i kaulana loa i kēia manawa ma nā ʻano ʻano like ʻole, e nānā pū kākou ma lalo.

ʻO ka paʻa ʻana o ka wai o ka methylcellulose e pili ana i kona nui hoʻohui, viscosity, particle fineness and dissolution rate. ʻO ka maʻamau, inā nui ka hoʻohui, liʻiliʻi ka fineness, a nui ka viscosity, kiʻekiʻe ka nui o ka paʻa ʻana o ka wai. I waena o lākou, ʻo ka nui o ka hoʻohui i ka hopena nui loa i ka nui o ka mālama ʻana i ka wai, a ʻaʻole kūlike ka pae o ka viscosity i ke kiʻekiʻe o ka paʻa wai. ʻO ka nui o ka hoʻoheheʻe ʻana ma muli o ke ʻano o ka hoʻololi ʻana o ka ʻili o nā ʻāpana cellulose a me ka fineness. Ma waena o nā cellulose ethers ma luna, ʻo ka methyl cellulose a me ka hydroxypropyl methyl cellulose i ʻoi aku ka nui o ka paʻa wai.

Hiki ke hoʻoheheʻe ʻia ka Methylcellulose i ka wai anuanu, a paʻakikī ke hoʻoheheʻe ʻia i ka wai wela. Paʻa loa kona hopena wai i ka pae o pH=3~12. He kūpono maikaʻi me ka starch, guar gum, etc. a me nā surfactants he nui. Ke piʻi ka mahana i ka mahana gelation, puka ka gelation.

Ma ke ʻano o ka hoʻohana pono ʻana o ka hydroxypropyl methylcellulose a mākou i hōʻike aku ai iā ʻoe ma luna, pono ia e huki i ka nānā a me ka nānā ʻana o kēlā me kēia mea hana, i mea e hōʻoia maikaʻi ai i ka hoʻohana ʻana o kēia huahana kemika.
