E like me nā waiwai o nā huahana i hoʻomākaukauʻia e ka hopena ethiofication, ua hoʻoholo keʻano koho.
I mea e hoʻoholo ai i ke kaʻina hana maikaʻi maikaʻi loa,ʻo keʻano o keʻano o ka antioxidant,ʻo Lyetic Actitic Acoitic ma mua. A laila e hana i ka papahana hoʻokolohua o ka hopena o ka mea hana hoʻokahi, e hoʻoholo i nā mea nui e loaʻa ana i ka hopena o ka huahana 2% Hōʻike nā hopena hoʻokolohua e like me nā mea i kohoʻia e like me ka nui o ka helu i kohoʻia, ka manawa o ka lua o ka lua o ka hana a pau i ka hana ka huahana. ʻO kahi hana hoʻokolohua Orthogonal meʻehiku mau kumu a me nā paeʻekolu i hukiʻia, a ua nānāʻia ka hopena o nā hopena kiʻekiʻe a me ka mana o kēlā me kēia kumu I mea e hoʻomākaukau ai i nā huahana me nā uku kiʻekiʻe he kiʻekiʻe kiʻekiʻe, a ua hoʻoholoʻia kahi hoʻolālā hoʻokolohua ma mua o nā hopena hoʻokolohua.
ʻO nā waiwai o ka mea kūʻai aku i hoʻomākaukauʻiahydroxythyl cellulouseua nānāʻia a ho'āʻoʻia, me ka hoʻoholoʻana o ka viscosity, ash spectory, etc. E kiʻi a hoʻohālikelike i keʻano o ka huahana,ʻo COBITUTUNTUNTED COCHESTUTIONS, MUARTALS CRITERS, CryalSallity, EtC. Crystallinity.
ʻO HydroxyEthyl Cellulouse, he mea nui i loaʻa i ka cedivase koʻikoʻi, ua loaʻa i ka nānāʻana ma muli o kona waiwai nui, revolika ʻO ka viscosity o ka celdroxythiyl cellulouse he hōʻailona koʻikoʻi loa o kāna hana. ʻO ka nānāʻana o ka viscosity o ka celdroxythyl celluluse ma luna o 5 × 104mpa · s, a he liʻiliʻi paha kaʻikepili lehu ma mua o 0.3%.
Ma kēia pepa, ua hoʻomākaukauʻiaʻo ViscosyIty Galcoryethyl Cellulouse e ka wai wai o ka wai ma o ka alkalization a me ka hoowahawaha. ʻO ke kaʻina hana alkalization ka hoʻomākaukauʻana o Alkali cellulouse. Koho mai nā ala alkalizationʻelua. ʻO kekahi ka mea e hoʻokaʻawaleʻia nā mea cellouse me ka acetone e like me ka dilila i kahi hopena sodium sodium ʻO ka mea'ē aʻeʻo ia ka mea e hoʻopauʻia ai keʻano cellousic i loko o ka sodium sodium hydroxide a me ka urea. Pono e laweʻia ka alkali nui loa i ka cellulouse alkali ma mua o ka hopena. Ma kēia pepa, ua aʻoʻia nā cell alkieloses a Alkali e ka maʻi uila a me X-ray diffraction.

I mea e hoʻoholo i nāʻanuʻu e hoʻomākaukau ai i kaʻoliʻana,ʻO nā mea aʻo o Antikolidant, a me nā Alkali a me Antio. ʻO nā mea nui e pili ana i ka hoʻomākaukauʻana i ka hoʻomākaukauʻana o ka celdroxythyl cellulouse e hoʻoholoʻia e nā mea hana hoʻokahi. E pili ana i ka waiwai o ka viscosity o ka huahana ma 2% o ka hopena kūpono. The experimental results show that the volume of diluent, the amount of ethylene oxide, the alkalization time, the temperature and time of the first and second rehydration have great influence on the product performance.
