Huina kemika: pūhui cellulose ether
ʻO QualiCell™ Hydroxyethyl cellulose ether (HEC) kahi papa o nā polymers hiki ke hoʻoheheʻe ʻia i ka wai. He pauda keʻokeʻo kahe kona ʻano. He ʻano ʻano hydroxylalkyl cellulose ether ʻo HEC i hana ʻia e ka hopena o ka cellulose me ka ethylene oxide i loko o ke ʻano alkaline. Hoʻopaʻa paʻa ʻia ke kaʻina hana e hōʻoia i ka paʻa o ka maikaʻi o nā huahana mai ka pūʻulu a i ka puʻupuʻu. Hoʻohana ʻia ka HEC maʻemaʻe kiʻekiʻe (kaumaha maloʻo) i ka mālama pilikino a me nā ʻoihana hoʻonaninani.
ʻO QualiCell™ hydroxyethyl cellulose solutions he pseudoplastic a i ʻole ka ʻāʻī ʻana i ka wai ʻemi. ʻO ka hopena, mānoanoa nā huahana mālama pilikino QualiCell™ i haku ʻia me ka hydroxyethyl cellulose ke lawe ʻia mai loko mai o ka pahu, akā palahalaha maʻalahi ma ka lauoho a me ka ʻili.
Hiki ke hoʻoheheʻe ʻia ʻo QualiCell™ hydroxyethyl cellulose i ka wai anuanu a i ʻole ka wai wela a hāʻawi i ka ʻike kiʻekiʻe i ka viscosity like ʻole. Eia kekahi, hiki ke hoʻoheheʻe ʻia ka hydroxyethylcellulose haʻahaʻa haʻahaʻa a hiki i ka medium molecular weight i ka glycerol a loaʻa ka solubility maikaʻi i nā ʻōnaehana wai-ethanol (a hiki i 60% ethanol).
Ua hoʻohana ʻia ʻo QualiCell ™ hydroxy ethyl cellulose ma ke ʻano he adhesive, adhesive agent, hoʻopiha i ka sima i hui pū ʻia, ka uhi a me ka fluorescent whitening agent additives, polymer coating, filtration control additives, wet strength agent, protective colloid, springback control and sliding reductant, rheological modifier, lubrication a mea hoʻonui operability, suspension stabilizer, shape keep strengthening agent and thickener.
Hoʻohana ʻia ʻo QualiCell ™ hydroxyethyl cellulose i nā mākeke like ʻole, me nā adhesives a me nā mea hoʻopaʻa, nā seramika kiʻekiʻe, ke kūkulu ʻana a me ke kūkulu ʻana, nā ceramics, ceramics, nā hale kūʻai a me nā lehulehu, ka ʻenehana aila a me ke kinoea, ka hoʻoheheʻe metala a me ka hoʻolei ʻana, nā pena a me nā uhi, nā huahana mālama pilikino. , lāʻau lapaʻau a me ka pepa a me ka pulp.
Structure
ʻO ke ʻano
ʻO ka hoʻoheheʻe wai kiʻekiʻe (ka wai anuanu a me ka wai wela), ka hydration wikiwiki; He ikaika ka hoʻopili ʻana i ka wai, ʻaʻole ʻike i nā ion a me ka waiwai pH; ʻO ka hoʻomanawanui paʻakai kiʻekiʻe a me ka hoʻohālikelike ʻana i ka surfactant.
