Ethyl cellulose hydrophilic a i ʻole hydrophobic

ʻO Ethyl cellulose kahi polymer synthetic i hoʻohana nui ʻia i nā ʻoihana like ʻole, me nā lāʻau lapaʻau, nā meaʻai, a me ka mālama pilikino. Ua ʻike ʻia no kāna mau ʻano hana kiʻiʻoniʻoni maikaʻi loa, kūpono kiʻekiʻe me nā mea ʻē aʻe, a me ke kūpaʻa maikaʻi ʻana i nā mea kemika a me nā mea kūlohelohe. ʻO kekahi o nā waiwai koʻikoʻi o ka ethyl cellulose ʻo kona hydrophobicity, ʻo ia ke ana o kona pili ʻana i ka wai.

ʻO ka Hydrophobicity kahi waiwai o kahi mea e wehewehe ana i kona manaʻo e hoʻokuke i nā mole wai. Ma keʻano laulā, ʻaʻole hiki ke hoʻoheheʻe ʻia nā mea hydrophobic i ka wai a makemake e hui pū me nā molekala hydrophobic ʻē aʻe. Hōʻike maʻamau ka Hydrophobicity e ka noho ʻana o nā pūʻulu nonpolar a i ʻole nā ​​​​polarity haʻahaʻa i loko o ke ʻano molekala, e like me nā kaulahao hydrocarbon a i ʻole nā ​​apo ʻala.

Manaʻo ʻia ʻo Ethyl cellulose he polymer hydrophobic ma muli o ka loaʻa ʻana o nā pūʻulu ethyl i kona ʻano mole. ʻO nā hui ethyl he nonpolar a me ka hydrophobic, a ʻo ko lākou hele ʻana e hoʻonui i ka hydrophobicity holoʻokoʻa o ka polymer. Eia kekahi, he haʻahaʻa haʻahaʻa ko ka ethyl cellulose o ka hoʻololi ʻana i nā pūʻulu ethyl, kahi e hoʻonui ai i kona ʻano hydrophobic.

Eia nō naʻe, hiki ke hoʻololi ʻia ka hydrophobicity o ka ethyl cellulose ma o ka hoʻololi ʻana i ke kiʻekiʻe o ka hoʻololi ʻana a i ʻole ma ka hoʻohui ʻana i nā pūʻulu hydrophilic i ka hale polymer. No ka laʻana, hiki i ka hoʻokomo ʻana i nā hui hydrophilic e like me ka hydroxyl a i ʻole nā ​​hui carboxyl hiki ke hoʻonui i ka hydrophilicity o ka polymer a hoʻomaikaʻi i kona solubility i ka wai. Hiki ke hoʻonui ʻia ke kiʻekiʻe o ka hoʻololi e hoʻonui i ka nui o nā pūʻulu hydrophilic a hoʻonui i ka hydrophilicity o ka polymer.

ʻOiai ʻo kona hydrophobicity, ua manaʻo ʻia ka ethyl cellulose he mea pono no nā noi like ʻole, ʻoi loa i ka ʻoihana lāʻau. ʻO kāna ʻano hydrophobic e lilo ia i mea pale maikaʻi loa no nā ʻōnaehana lawe lāʻau, no ka mea hiki iā ia ke pale i ke komo ʻana o ka wai a i ʻole nā ​​​​mea hydrophilic ʻē aʻe i loko o ke ʻano dosage. Hiki i kēia ke kōkua i ka pale ʻana i ke kūpaʻa a me ka pono o ka lāʻau lapaʻau no ka manawa lōʻihi.

I ka hōʻuluʻulu ʻana, ʻo ka ethyl cellulose kahi polymer hydrophobic ma muli o ka loaʻa ʻana o nā pūʻulu ethyl nonpolar i loko o kāna ʻano mole. Eia nō naʻe, hiki ke hoʻololi ʻia kona hydrophobicity ma ka hoʻololi ʻana i ke kiʻekiʻe o ka hoʻololi ʻana a i ʻole ka hoʻohui ʻana i nā pūʻulu hydrophilic i ka hale polymer. ʻOiai ʻo kona ʻano hydrophobic, ʻo ka ethyl cellulose kahi mea pono no nā noi like ʻole, ʻoi loa i ka ʻoihana lāʻau.
