Ua like anei ka hydroxymethylcellulose me ka hydroxypropyl methylcellulose?

Hoʻokumu ʻia ʻo Carboxymethyl cellulose (Carboxymethyl cellulose) e ka hopena o ka hui hydroxyl o ka hui anhydroglucose ma ke kaulahao cellulose me ka hui etherification (chloro Z acid a i ʻole ethylene oxide);

He mea amorphous kala ʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai, ka wai alkali wai, ka ammonia a me ka cellulose solution, hiki ʻole ke hoʻoheheʻe ʻia i loko o ka hopena organik a me ka ʻaila mineral; hiki ke hoʻohana ʻia e like me ka nui, calendering a me ka mānoanoa ma ka ʻoihana textile;

Mea hoʻonohonoho i ka hana pepa a me ka papa;

Reabsorption o nā haumia i loko o nā mea hoʻomaʻemaʻe synthetic;

ʻO ka mea hoʻoheheʻe no ke koho ʻana i ka copper-nickel a me ka potassium ore;

ʻO ka mānoanoa a me ka stabilizer viscous i ka wā e wili ai i ka ʻaila a me nā luawai kinoea;

ka hoʻohui ʻana i ke kāpili no ka wallpaper;

nā mea hui hana maloʻo;

Nā mea pena wai latex, etc.

ʻO ka Hydroxypropyl methylcellulose (Hypromellose, Cellulose) i hana ʻia me ka pulupulu maʻemaʻe maʻemaʻe ma ke ʻano he mea maka, i hoʻoheheʻe ʻia ma lalo o nā kūlana alkaline, ʻaʻole i loaʻa i nā mea hana e like me nā kino holoholona a me nā aila. Hiki ke hoʻoheheʻe ʻia i loko o ka wai a me ka hapa nui o ka polar a kūpono o ka ethanol/wai, propanol/wai, dichloroethane, etc., hiki ʻole ke hoʻoheheʻe ʻia i ka etera, acetone, a me ka ethanol paʻa, a pehu ʻia i loko o kahi hopena colloidal maʻemaʻe a liʻiliʻi paha i loko o ka wai anuanu. Loaʻa i ka hoʻonā wai i ka hana ʻili, ke ʻike kiʻekiʻe a me ka hana paʻa.

Loaʻa i ka HPMC ka waiwai o ka thermal gelation. Hoʻomaʻamaʻa ʻia ka hopena wai wai e hana i kahi gel a hoʻoheheʻe ʻia, a laila hoʻoheheʻe ʻia ma hope o ka hoʻoilo. ʻOkoʻa ka mahana gelation o nā kikoʻī like ʻole. ʻokoʻa ka solubility me ka viscosity. ʻO ka haʻahaʻa o ka viscosity, ʻoi aku ka nui o ka solubility. Loaʻa i nā kikoʻī like ʻole o HPMC kekahi mau ʻokoʻa i kā lākou mau waiwai. ʻAʻole pili ka hoʻoheheʻe ʻana o HPMC i ka wai e ka waiwai pH.
