2.1 Ka hopena o nāʻikepili Cellouse Ether i nā waiwai maʻamau
Me ka hoʻonui i kaʻike, ua hoʻomaikaʻi nui ka hana a me nā palu o ka meaʻala, aʻo ke kumu'ekikuʻekuʻe hōʻelima, a me ka wahi hana koʻikoʻiʻo Paena, a me ka pāpū Ua hoʻomaikaʻi nuiʻia a me nā aesthetics. I ka manawa like, uaʻai ka wai o ka lepo i hiki ke hoʻonui nuiʻia. A 52, Piʻi ka wai wai ma 102%,ʻO ka manawa hope e lōʻihi ka lōʻihi o ka 100 min, ia ka 2.5 mau manawa i nā hana maʻamau. ʻO nā mea maʻamau i nā mea hana mua o ka papa o ka papa e hoʻemi nuiʻia me ka hoʻonuiʻana o nāʻike o ka Eter Cellouse Ether. I ka manawa i emi ai kaʻike o ka celloulse eter i ka 5 ‰, ka ikaika o ka ikaika o ka 24 H flexural ikaika a me ka ikaika ʻO ka ikaika o ka mana he 39.47% a me 23.45% o keʻano o keʻano pohō. He mea kūpono kēia me ka hoʻonuiʻiaʻana o ka nui o ka nui o ke ahi, mai 2069 Kg / m3 ma ka emiʻana o 15.56%. ʻO ka nui o ka hōʻino o ka morina i hoʻemi a hoʻonui i ka pososity,ʻo ia kekahi o nā kumu no kaʻikeʻana i nāʻano o nā mea hana.
ʻO Cellouse EterʻO kahi polymerʻaʻohe mea polymer. Hiki i nā pūʻulu hydroxyl ma ke kaula cellouse ether eter a me nā oxygen atoms e hiki ai i ka wai o ka wai i loko o ka wai hydrogen Macroscopically ua hōʻikeʻiaʻo ia ma keʻano he nui o ka pīpī o ka slurry [5]. E hoʻonui i ka hoʻonuiʻana i ka visa slirry I ka wā hoʻohālikelikeʻana i ke kaʻina hana, Hoʻokomoʻia i kahi nui o ka'ōmaka lele. E hana nā voids e like me ka ikaika o ka mortin Ke noʻonoʻo nei i ka hoʻohanaʻana i ka wai unilateral unilateral o keʻano o ka mortar
2.2ʻO ka hopena o ke molela molecular o ka celilouse ether ma ka hana o ka mory
ʻO ka maʻamau,ʻoi aku ka kiʻekiʻe o ka viscosity a me ka nui loa i ka maikaʻi o ka eter,ʻoi aku ka maikaʻi o ka wai. e hanaʻinoʻia ka hana. No laila,ʻo ka mana o nā mea e pili ana i nā kaupaona o nā mollecular'ē aʻe ma nā kumuwaiwai likeʻole o nā kumuwaiwai gypsum Ka nui o ka wai e hoʻonui ai i ka lepo i kahi ākea, akāʻaʻohe hopena maopopo loa i ka manawa a me ka wai. I ka manawa like, ua emi iho ka ikaika o ka pālaha o nā'āpana i nāʻokoʻa'ē aʻe, akā ua liʻiliʻi loa ka decline i ka mana o ka celllues. I ka hōʻuluʻuluʻana, ka hoʻonuiʻana o ka nui o ka molena o ka molulate o ka cellulose eter i ka hopena o ka hana o ka mortar mumternary. Ke noʻonoʻo nei i kaʻoluʻolu o ka kūkuluʻana, e kohoʻia nā vole-mole-mole-mole-molluluse-molouluse
2.3 Ka hopena o ka cellouse ether ma ka wela o ka hydration o ka gypsum despsum
Me ka hoʻonuiʻana o nāʻikepili o ka collulose ether keʻano o ka hydration o ka pānaʻi o ka hydral, aʻaʻole i emi iki ka manawa o ka hywards. Hōʻike kēia i ka celloulse ether ke hiki ke hoʻopau i ka helu hydration a me ka hydration kiʻekiʻe o ka gypsum i loko o 1 ‰. Hiki keʻikeʻia he kiʻi kiʻi o ka colloidal ma hope o nā mea e hālāwai ai ka wai ma hope o ka wai o ka gypsum o ka gypsum ma mua o 2 h. I ka manawa like,ʻo ke kiʻiʻana o kona mau waiʻokoʻa a me nā hopena nui e hoʻolōʻihi i ka neʻeʻana o ka wai o ka wai a me ka weheʻana i keʻano o ka gypsum o ka gypsum. E hōʻuluʻuluʻia, i ka wā e hoʻokeleʻia ai ka Dosage kūpono,ʻo Celoulouse eter i ka hopena o ka helu hydration a me ka hydration kiʻekiʻe o ka gypsum dypsum nona. I ka manawa like, e hoʻonui nuiʻia ka hoʻonuiʻana o ka cellulouse a me ke kaumaha o ka molecular I mea e hōʻoia ai i ka hāʻule o ka uluʻana o Gyrlucuried Gesting, e hoʻonui loa ka holoi lauoho,ʻo ka wai ka wai wai nui, ka mea ma muli o ka manawa e hoʻolōʻihi i ka pae o ka pahū. ʻO ke kumu nui no ka emiʻana o nā waiwai mechaninical.

(1) Aia i ka wa o ka wai me he oihana mana, me ka hoʻonui nuiʻana o ke kuʻikahi enerful ua hoʻohālikelikeʻia me kaʻikepili, ke kaumaha o ka molena o ka celilouse eter ka nui o ka hoʻonuiʻana i nā mea ma luna o ka pastar. Ke noʻonoʻo nei i nā mea i hiki ke kohoʻia, e kohoʻiaʻo Cellouse ether me kahi kaumaha liʻiliʻi (Viscosity ma mua o 20 000 Pa ·
(2)ʻO nā hopena hōʻike o ka wela wela o ka wela o ka gypsum desplirized e hōʻike ana i loko o ka pakuhi o kēia hoʻokolohua a me keʻano hydration o ka gypsum. ʻO ka hoʻonuiʻana i kaʻai wai a me ka hōʻemiʻana i ka nui o ka nui o ka nui o nā mea waiwai nui o nā mea hana o ka gypsum-gypsum.
