ʻO Hydroxyethyl cellulose (hec) he polymer. I mea e hoʻomaopopo pono ai i kēia, pono mākou eʻimi i nā kuʻuna kumu o nā pupule, keʻano o ka colluluse a me kona mau noi.
1. Nā manaʻo kumu o nā polymers
ʻO nā polyms i hoʻopiliʻia e nā mea hoʻohuihui macromolecular i hoʻokumuʻia e ka helu nui o nā'āpana hou (i kapaʻiaʻo Monomers ʻO kēia mau monors e hana i nā hana lōʻihi loa ma o nāʻano polommomishization e hāʻawi ana i nā polymomer E like me kā lākou mau kumuwaiwai, hiki ke hoʻokaʻawaleʻia nā polymers i loko o nā polymers kūlohelohe a me nā polyhetic. Hoʻokomoʻia nā mea kūlohelohe maoli, he carkein, a me ka'ōpala kūlohelohe; Hoʻokomo pū nā mea hana maikaʻi i ka polyhetic me Polythylene, polystyrene, a me polyvinyl chiredide.
2. Cellulouse a me kānaʻano
ʻO ka cellulouse ka mea nui loa o ka hui pūʻana o ka polymer i keʻano, i loaʻa i ka nui o nā wahi kanu. ʻO Cellulouse kahi polysacCharchider i hoʻopiliʻia i nā hui o β-d-gl-glucose e hoʻopiliʻia e β (1 → 4) i keʻano kiʻekiʻe. Ma muli o kāna mau'āpana glucose i hana houʻia, he cellulouse ia he polymer kūlohelohe maoli.

ʻO Hydroxyethyl cellulouse he derivative o cellulouse, i loaʻa ma o ka hoʻolaunaʻana ma ka hoʻolahaʻana i ka collecular molecular molecular. ʻO nā mea kūpono loa, celoulose e pili ana i ka chlorotate a iʻole chlorotate a iʻole etyl chlorotate i lalo o nā kūlana alkalineth
Hoʻonohonohoʻia,ʻo Hydroxyethyl Cellulouse e hoʻomau i ka hana lōʻihi,ʻo ia hoʻi,ʻo ia hoʻi, he kaulahao nui i hoʻohuiʻia i kahi nui o nā'āpana nui. Eia nō naʻe, ua hoʻololiʻia kekahi mau pūʻulu hydroxyl e nā hui hydroxythiyl, aʻo kēia hoʻololi e lilo i nāʻano collulse a me nā hiʻohiʻona solcosity a me nā hiʻohiʻona viscosit. ʻOiai ka hoʻokumuʻana i nā mea hoʻopukaa, he kīʻaha kiʻekiʻe kīʻaha hydroperathyl, a he mau'āpana mana nui, aʻo konaʻano molulari i hoʻopaʻaʻia, a mau nō hoʻi i ka weheweheʻana o kahi Pollymer.
4.ʻO nā waiwai o ka hydryethyl cellulouse
E like me ka polymer,ʻo ka hydryethyl cellulose i kekahi mau mea maʻamau polymer likeʻole:
ʻO ke kaupaona molela kiʻekiʻe
ʻO nā mea waiwai:ʻo ka celluluseyl hydroese e hiki ai i kahi hopena colcoud colcous colcolidal sollidal ma ke anuanu a me ka wai wela. ʻO ka mākaʻikaʻi o kāna hoʻonā e pili ana i ka mika i ke kaumaha a me ke kiʻekiʻe o keʻano. ʻO kēia waiwai nui ke koʻikoʻi nui i nā noi he nui.
ʻO ka Thermosensities:ʻO keʻano o ka viscosity o ka hopena hydroxythyl e loli me ka mahana, e hōʻike ana i ka mea maʻamau
ʻO kā SPICkening a me nā kiʻi kiʻi kiʻi kiʻi: Ma muli o ke komoʻana a me ka hoʻopiliʻana o kona mau kaulahao poloun
V. Ke noi aku nei o ka cellulose cellulose
Ma muli o kona mau mea 'ano polymerʻokoʻa,ʻo hydryyethyl cellulose i hoʻohana nuiʻia ma nā mahina he nui. Eia kekahi mau noi maʻamau:
ʻO nā mea waiwai: Ma keʻano o ka cement additive, hiki i ka cellulose cellulose e hoʻomaikaʻi i ka flirity a hoʻomaikaʻi i ka hana o ka nohoʻana.
ʻO nā pāpale a me nā pena: i loko o nā coatist, hoʻohanaʻiaʻo hec ma keʻano he skickener, stabilizer a me nā kiʻi kiʻi kiʻi a me ke kiʻiʻana o ka pākeke.
Nā mea hana
ʻO ka hana pepa: Ua hoʻohanaʻiaʻo Hec i ka papaʻaina pepa a me ka hoʻoiliʻana e hoʻomaikaʻi i ka paleʻana i kaʻili a me nā paʻi paʻi o ka pepa.
ʻO nā cosmetics: Ua hoʻohana nuiʻiaʻo Hec i loko o nā aila, nā mea nānā a me nā huahana mālama maka.
ʻO kēia mau noi e hoʻohana pono ai i nā Palmer Properties o ka Celdroxyethyl celclous
ʻO HydroxyEthyl Cellouse kahi polymer i loaʻa ma o ka hoʻololiʻana i keʻano o keʻano o ka cemikina o ka cellouse. ʻO kānaʻano molecular i loaʻa i kahi helu nui o nā hui glucose, e mālama mau ana i nā hiʻohiʻona o ke kaumaha kiʻekiʻe a me ka chaincture ma hope o keʻano o ka chinclus kiʻekiʻe. Hōʻikeʻo Hydroxyethyl Cellulous i nā waiwai polymer maʻamau e like me ka viscosity kiʻekiʻe, ka hopena No laila, hiki ke hoʻomaopopo maopopo iā ia he cellulousthyl cellulouse he polymer koʻikoʻi.
