ʻO Hydroxypropyl methylcellulose, ʻike ʻia hoʻi he hypromellose a me cellulose hydroxypropyl methyl ether, i hana ʻia mai ka pulupulu pulupulu maʻemaʻe loa a ua hoʻomaʻamaʻa kūikawā ʻia ma lalo o nā kūlana alkaline.
ka ʻokoʻa:
ʻano ʻokoʻa
Hydroxypropyl methylcellulose: keʻokeʻo a keʻokeʻo paha e like me ka pauka a i ʻole granules, nona nā ʻano non-ionic i loko o ka hui cellulose, ʻo kēia huahana he semi-synthetic, inactive viscoelastic polymer.
ʻO ka hydroxyethyl cellulose he keʻokeʻo a melemele paha, ʻaʻohe ʻala, ʻaʻohe mea ʻawaʻawa a i ʻole ka pauka paʻa, ʻo ka mea kumu nui he alkali cellulose a me ka ethylene oxide etherification, ʻo ia ka non-ionic soluble cellulose ether.
He ʻokoʻa ka hoʻohana ʻana
I loko o ka ʻoihana pena, hydroxypropyl methylcellulose ka hoʻoheheʻe maikaʻi ʻana i ka wai a i ʻole nā mea hoʻoheheʻe organik e like me ka mānoanoa, dispersant a me ka stabilizer. Hoʻohana ʻia ʻo Polyvinyl chloride e like me ka wehe ʻana i ka pena no ka polymerization suspension e hoʻomākaukau ai i ka polyvinyl chloride, i hoʻohana nui ʻia i ka ʻili, nā huahana pepa, nā huaʻai a me ka mālama ʻana i nā mea kanu, nā textiles a me nā ʻoihana ʻē aʻe.
Hydroxypropyl methylcellulose: aneane hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol piha, ether, acetone; hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a i ʻole turbid colloidal solution, hoʻohana nui ʻia i nā uhi, inks, fibers, dyeing, papermaking, cosmetics, pesticides, minerals Product processing, oil recovery and pharmaceutical industry.
ʻokoʻa solubility
Hydroxypropyl methylcellulose: aneane hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol piha, ether, acetone; hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a i ʻole ka wai anuanu.
Hydroxyethyl cellulose (HEC): Hiki iā ia ke hoʻomākaukau i nā hāʻina ma nā pae viscosity like ʻole, a loaʻa iā ia nā waiwai hoʻoheheʻe paʻakai maikaʻi no nā electrolytes.
