1. OwauTYDSDSYYSLYLOYLLLYLLLYLLYL CELLULUA
HydrexxypopypoprowlseHeʻano hoʻohāliʻu manuʻa paha i ka hopena o ka mea hana a me kaʻaiʻana e hoʻonui wikiwiki ana. ʻO ia kahi cellulose i huiʻia i huiʻia e ka eter i hanaʻia ma hope o ka paleʻana i ka cotton ma hope o ka alkalization, e hoʻohana ana i nāʻano o ka eteryl. ʻO ke kiʻekiʻe o ka hoʻololiʻana he 1.2 ~ 2.0. ʻO kona mau mea waiwai e hōʻike ai ma muli o ka pae o kaʻike o ka methoxyl i nāʻike i hydroxypropyl.
(1) Ke maʻalahi maʻalahi nā hoʻohemoʻana o ka hydroxxyl mathylChelose i ka wai anuanu, a e hālāwai me ka pilikia ma ka wai wela. Akāʻo konaʻano hoʻonaʻauao nui ma ka wai wela,ʻoi aku ka kiʻekiʻe ma mua o ka makika o Mathyl Cellowse. ʻO ka pale kūlohelohe i ka wai anuanu nui e hoʻolōʻihiʻia ai nā wai me ka huiʻana o ka mollulse.
(2) (2) ka viscosity o ke aniani hydrochespopyl e pili ana i kona kino kūlohelohe, hoʻi ka kiʻekiʻe loa. Pākuʻi pū kahiʻano i kona mau viscomeness, e hoʻonui anaʻo ia mahana. Eia nō naʻe,ʻo ka hopena o kona mau viscosity kiʻekiʻe a me keʻano haʻahaʻa ma lalo o ka materllse cellulose. Ke kūpaʻa nei kona hopena i ka wā i mālamaʻia ai ma ka mahana o ka lumi.
(3)ʻO ka mālamaʻana o ka wai o hydroxxypopall mathrelcelusure e pili ana i kona nui,ʻikeʻia ka nui o ka nui o ka celcoulse.
(4) Ua paʻa nā maʻi hydroxypopall mathrolcelllose i ka ACID lāuaʻo Alkali, a me kona hopena kūpono loa i ka laulāʻo PH = 2 ~ 12. He hopena ka hohonuʻo Caustic a me nā wai liʻiliʻi i kāna hana, akā ho'ōlaʻo Alkanali e kiʻi i konaʻano kuʻeʻana a hoʻonui i konaʻano kapa kolohe. Kūponoʻiaʻo hydroxyprooparluroll
(5) Hoʻokaʻaʻia ka hydroxyprooparllurel mathylChelose me ka wai waiʻalā e hana ai i kahi maʻi homogeneous kiʻekiʻe. E like me ka polyvinyl agan, starch ether
(6)ʻO ka hydroxyprooppopyl midylcelllose iʻoi aku ka maikaʻi ma mua o ka mitzymellse, a emi mai kona hopena ma nā othylcellse.

2, hydrxythyl cellulouse
Hanaʻia ia mai ka paleʻana i ka'ōpala i hanaʻia me Alkali, a ua hanaʻia me Etelenene Offent i keʻano o ka intoproopanol. ʻO kona kiʻekiʻe o keʻano he nui loa 1.5 ~ 2.0. He hydrophinicity ikaika a maʻalahi hoʻi e hoʻopili i ka'ōpū.
(1) He meaʻalaʻo HydroxyEtl ma ka wai anuanu, akā he mea paʻakikī ke hoʻokaʻawale i ka wai wela. ʻO kāna hoʻonā e paʻa ana ma ke kiʻekiʻe kiʻekiʻe me keʻanoʻole. Hiki ke hoʻohanaʻia no ka manawa lōʻihi ma lalo o ka mahana kiʻekiʻe i loko o ka martar, akā he haʻahaʻa ka wai o ka wai ma mua o ka cellulose cellulouse.
(2)Hydroxythyl cellulouseUa hoʻokūkū anei iā Alcali a me Alkali, aʻo Alkali hiki iā Alkili hiki i kona hoʻopaʻapaʻa a hoʻonui aʻe i kona helehelena. ʻO ka mea hoʻowahāwahā i loko o ka wai iʻoi aku ka maikaʻi ma mua o kēlā o ka cellulose cellulouse a me hydroxyproopyl milllulse.
(3)ʻO ka CeldroxyEtyl Cellulouse he maikaʻi anti-sag hana no ka mory, akā he manawa hou loa no ka nohoʻana.
(4)ʻO ka hana o ka Celdroxythyl Cellulouse e hanaʻia e kekahi mau kikowaena home e like me ka mea nui o ka wai
) I kahi mahana e pili ana i ka 40 ° C, e hele mai paha ma loko o 3 a 5 mau lā, e pili ana i kāna hana.
