Hoʻoheheʻe ʻia o nā huahana Methyl Cellulose

ʻO ka methyl cellulose he polymer hiki ke hoʻoheheʻe ʻia i ka wai i hoʻohana nui ʻia i nā noi ʻoihana like ʻole. ʻO ka solubility o nā huahana methyl cellulose e pili ana i nā kumu like ʻole, me ke ʻano o ka hoʻololi ʻana, ke kaumaha molekala, ka mahana, a me ka pH.

ʻO nā huahana methyl cellulose me kahi haʻahaʻa haʻahaʻa o ka hoʻololi a me ke kaumaha molecular haʻahaʻa i ʻoi aku ka maʻalahi i ka wai ma mua o nā huahana me kahi kiʻekiʻe o ka hoʻololi a me ke kaumaha molecular kiʻekiʻe. ʻO nā huahana methyl cellulose me kahi kiʻekiʻe o ka hoʻololi ʻana a me ke kaumaha molekala kiʻekiʻe ke koi aku i nā mahana kiʻekiʻe a i ʻole nā ​​manawa hui ʻoi aku e hoʻoheheʻe loa i ka wai.

Hiki i ka pH o ka hopena ke hoʻopili i ka solubility o ka methyl cellulose. Hiki ke hoʻoheheʻe ʻia nā huahana Methyl cellulose i loko o nā ʻoluʻolu kūʻokoʻa a i ʻole ka ʻakika liʻiliʻi. Ma nā koina pH kiʻekiʻe, emi ka solubility o ka methyl cellulose. ʻO kēia ma muli o ka ionization o nā pūʻulu hydroxyl ma ka iwi kuamoʻo cellulose, hiki ke hoʻemi i ka hiki o nā mole wai wai e launa pū me nā kaulahao polymer.

Ma waho aʻe o ka wai, hiki ke hoʻoheheʻe ʻia nā huahana methyl cellulose i kekahi mau mea hoʻoheheʻe kūlohelohe, e like me ka ethanol, methanol, a me ka acetone. Eia nō naʻe, ua kaupalena ka solubility o ka methyl cellulose i loko o kēia mau mea hoʻoheheʻe a hilinaʻi i ke degere o ka hoʻololi ʻana a me ke kaumaha molekala o ka huahana.

I ka hopena, pili ka solubility o nā huahana methyl cellulose i nā kumu like ʻole, me ke ʻano o ka hoʻololi ʻana, ke kaumaha molekala, ka mahana, a me ka pH. ʻO nā huahana methyl cellulose me kahi haʻahaʻa haʻahaʻa o ka hoʻololi ʻana a me ka haʻahaʻa haʻahaʻa molekala ʻoi aku ka hoʻoheheʻe ʻana i ka wai, ʻoiai nā huahana me kahi kiʻekiʻe kiʻekiʻe o ka hoʻololi ʻana a me ke kaumaha molekala kiʻekiʻe ke koi aku i nā mahana kiʻekiʻe a i ʻole nā ​​​​manawa hui ʻoi aku e hemo loa. Hiki ke hoʻoheheʻe ʻia nā huahana Methyl cellulose i loko o nā ʻoluʻolu kūʻokoʻa a liʻiliʻi paha, a hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe kūlohelohe, akā ua kaupalena ʻia ka solubility i loko o kēia mau solvents.
