ʻO ka hoʻomākaukau a me ka noiʻana o ka hydroxyprooppyl milll cellulose

ʻO Hydroxyproopsl Methill cellulouse ʻO ka huiʻo Hydroxyproopsl He semi-synthetic

Ka hoʻomākaukauʻana o
ʻO ka Praft pepa Praft me nā mea e pono aiʻo α-cellulose o 97%, intrinsic viscosity of 49% Naoh Ua hoʻopauʻia ka pulp hopena e wehe i ka nui o 49% Naoh Aqueous Soluput e loaʻa iā Alkali Celoulouse. ʻO ka nui o ke kaupaonaʻana o (49% Naoh i ka wai) i (ka hopena paʻa ma ka umauma o ka cell) i loko o ka unahi helu) i 1.49. ʻO ka Alkali Cellulose (20kg) i loaʻa i loko o kahi mea kūʻai aku ma keʻano o kaʻoihana kūloko a me ka hoʻomaʻemaʻeʻana me ka oxorgen ma ka oxygen. A laila, ua ho'ōlaʻia ka ma keʻano ma ka rectionso ma 60 ℃, aʻoʻia kaʻano o ka lāʻau kūloko. A laila, 2.4KG o Dimometl Ether a ua hoʻohuiʻia ka mahana ma kaʻaoʻao o ka cectory ʻO ka huiʻana ma Plup) 1.97, aʻo ke ahiahi ma ka hana i kāohiʻia mai ka rectors mai 80 ° a 90 ℃. Eia kekahi, ua mālamaʻia ka hopena ma 90 ° C no 20 mau minuke. A laila, hoʻokuʻuʻia ke kino mai ka reactors, a ua hoʻoneʻeʻia ka curde hydroxypropropyl millroll cellulose mai ka reactors. ʻO keʻano o keʻano o ka crude hydroxypopplayl middlcellse he 62 ℃ i ka wā i laweʻia ai. E ana i ka nui o ka helu o ka nui o ka pā o ka nui o keʻano he nui o keʻano o keʻano he nui o ka moddrocello Ma muli o kahi hopena, ka nui o ka nui o ka nui o nā'āpana paʻakikī o nā'āpana he 6.2mm. ʻO ka mea i loaʻa i ka cound hydroxypopyl methylcelll minika mau ciaxial (t = 10.2, ka wikiwiki o ka letkrcellose. E like me ke anaʻana me ka hoʻohanaʻana i nā kiʻiʻelima me nā'āpana weheʻokoʻa,ʻo ka nui o ka nui ma mua o 1.4mm. Ua loaʻa i ka Slurry ma ka hoʻohuiʻana i ka wai wela ma ka 80 Ua hōʻehaʻia ka slurry i kahi wela o 80 ° C no 60 mau minuke. A laila, hāʻawiʻia ka slurry i kahi kānana slimat single stock (bhs sonthofen huahana) me kahi wikiwiki o 0.5 rpm. Ka hapalua o ka slurry he 93 ℃. Ua hāʻawiʻia ka slurry e kahi pākuʻi me kahi koina e hoʻokuʻu i ka 0.2MPA. ʻO ka nui o ka weheʻana o ka kānana paʻakikī o ke kiʻiʻoniʻoniʻo 80μm, aʻo ka'āpana kānana he 0.12m2. Ua hāʻawiʻia ka mea smury i ka kānana hoʻoweliweli pīhoihoi peʻaka me ka kānana a hoʻohuliʻia i ka pōpoki kānana. Ua hānaiʻia ka pōkole hopena me ka steam o 0.3mpa a me ka wai wela ma 90 Ua hoʻolakoʻia ka wai wela e ka pākuʻi me kahi koina discharge o 0.2mpa. Ma hope o ka pauʻana o ka wai wela, ua hāʻawiʻia 0.3mpa o ka Steam. A hemo ka huahana i loko o ka poʻohiwi o ka kānana, ma laila ma kaʻuʻuku a weheʻia ka mea nāna i pale aku. Nā hana hoʻomau mai ka hāʻawiʻana i ka slurry i ka hoʻokuʻuʻana o ka huahana holoi holoiʻia. ʻO ka wai o ka wai o ka huahana i holoiʻia he 52.8% e like me ke anaʻana e ka hoʻomehana maloʻoʻana i ka hygrometer. Ua hoʻokuʻuʻia nā huahana i holoiʻia mai ka kānana kīwī nui i ka hoʻohanaʻana i kahi hau uila ma 80 ° C i loaʻa i ka maʻi hydrocrelllulose.
