Ke kūlana hoʻomohala o ka ʻenehana hana HPMC a me ke kaʻina o ka hydroxypropyl methyl cellulose ma Kina

Hydroxypropyl methyl celluloseHPMCʻO ka hana o ka home i kēia manawa ua hāʻawi mua ʻia me ka ʻenehana ʻenehana wai, ua hōʻike ʻia kēia ʻenehana e ka wuxi chemical industry research and design institute ma China research unit i nā makahiki 1970, nā mea noiʻi i loaʻa ma ke kumu o ka hoʻolaha ʻana, ʻo ke kumu maoli ke ʻano o ka etherification reaction, no ka mea, ʻaʻole i kūpono nā mea hana i ko mākou ʻāina, a laila hana ʻia ke kaʻina hana wai ʻano etherification reaction. nā mea hana cellulose ether.

Hoʻohana maʻamau ka hana ʻana o ka home hydroxypropyl methyl cellulose HPMC i ka pulupulu i hoʻomaʻemaʻe ʻia e like me ka mea maka (ua hoʻomaka kekahi mau mea hana e hoʻohana i ka pulp lāʻau), a me ka grinder home e wili a hoʻohana pono i ka alkalization pulupulu i hoʻomaʻemaʻe ʻia, etherification me ka hoʻohana ʻana i ka mea hoʻoheheʻe kūlohelohe binary, ka hopena i ka reactor vertical. Hoʻohana ke kaʻina hana hoʻomaʻemaʻe i kahi kaʻina hana e hoʻoneʻe ʻia ai ka mea hoʻoheheʻe organik i loko o kahi reactor a hoʻomaʻemaʻe ʻia ka huahana maʻemaʻe ma o ka holoi ʻana a me ka wai maloʻo ma o nā scrubbers a me nā centrifuges. Hoʻopau ʻia ka hana ʻana o ka huahana me ka granulation intermittent, ma lalo o ke kūlana hoʻomehana (aia kekahi mea hana me ka ʻole o ka granulation), ka maloʻo a me ka ʻoki ʻana i ke ʻano maʻamau, ʻo ka hapa nui o ka hana kūikawā e hoʻopaneʻe wale i ka manawa hydration o ka huahana (wikiwiki hoʻoheheʻe) ka hana ʻana me ka pale ʻole a me ka hoʻoili ʻana, hoʻohana ʻia i ka manual ala.

Loaʻa i ke kaʻina hana wai nā mea maikaʻi aʻe: liʻiliʻi ke kaʻina hana ʻana i ke kaomi kūloko, haʻahaʻa ka pono o ka hiki ke koi, liʻiliʻi ka pilikia; Ma hope o ka hoʻokomo ʻana i ka lye,cellulosehiki ke hoʻonui piha ʻia a like me ka alkalized. ʻOi aku ka maikaʻi o ka infiltration a me ka pehu o ka cellulose. He liʻiliʻi ka reactor etherification, i hui pū ʻia me ka pehu like o ka cellulose alkali, no laila ua maʻalahi ka maikaʻi o ka huahana, hiki ke loaʻa ke degere hoʻololi a me ka viscosity i nā huahana like ʻole, maʻalahi hoʻi ke hoʻololi.

Eia nō naʻe, loaʻa i kēia kaʻina hana nā hemahema: ʻaʻole nui loa ka reactor, ʻo nā palena helu helu e alakaʻi i kahi mea hana liʻiliʻi, i mea e hoʻomaikaʻi ai i ka huahana, pono e hoʻonui i ka nui o nā reactors; Pono nā huahana i hoʻomaʻemaʻe ʻia a hoʻomaʻemaʻe ʻia i nā mea hana hou aku, ka hana paʻakikī, ka ikaika o ka hana; No ka mea, ʻaʻohe anti-mildew a me ka hoʻohuihui ʻana, e hopena i ka paʻa o ka viscosity huahana a pili nā kumukūʻai hana; Packaging ma ke ala lima, ka ikaika o ka hana, ka uku hana kiʻekiʻe; ʻOi aku ka haʻahaʻa o ka pae automation o ka hoʻomalu ʻana ma mua o ke kaʻina hana kinoea, no laila haʻahaʻa loa ka pololei o ka mana. Hoʻohālikelike ʻia me ke kaʻina hana kinoea, pono nā ʻōnaehana hoʻihoʻi solvent paʻakikī.

Me ka hoʻomaikaʻi ʻana o ka home hydroxypropyl methyl celluloseHPMCʻenehana hana, ʻo kekahi mau ʻoihana ma o ka hoʻomau kūʻokoʻa kūʻokoʻa, ua hoʻomohala ʻia ke ʻano hana wai wai nui e ka lele a me nā ʻano, a loaʻa iā ia nā ʻano ʻenehana ponoʻī. Ke hoʻohana nei ʻo Anxin chemistry i ke kaʻina hana HPMC kumu, ʻaʻole wale ke kaʻina hana i kūpono, pololei a hilinaʻi nā ʻāpana hoʻokele hana, ka hoʻohana piha a me ke kūpono o nā mea maka a me nā ʻano ʻē aʻe, a ʻokoʻa ke kiʻekiʻe o ka huahana. Ua hoʻololi ʻia ka laina hana HPMC o kekahi mau ʻoihana, e hoʻokō i nā koi o ka DCS automation control, nā mea e pili ana i ka wai, nā mea paʻa paʻa hiki ke hoʻohana ʻia e ana pololei a hoʻohui i ka ʻōnaehana DCS, ka mahana a me ke kaomi ʻana i ke kaʻina hana ua ʻike ʻia ka DCS mana a me ka nānā mamao mamao, Ma ke ʻano o ka hiki, ka hilinaʻi, ka paʻa a me ka palekana o ka hana, ʻike ʻia ka hoʻomaikaʻi ʻana i ke kanaka, ʻaʻole i hoʻohālikelike ʻia me ka hana maʻamau. hoʻomaikaʻi i ke kaiapuni hana ma ka pūnaewele.
