He aha ka hoʻohana nui o ka hydroxypropyl methylcellulose?
——Pane: Hoʻohana nui ʻia ʻo HPMC i nā mea hana, nā uhi, nā resins synthetic, ceramics, lāʻau lapaʻau, meaʻai, textiles, mahiʻai, mea hoʻonaninani, paka a me nā ʻoihana ʻē aʻe. Hiki ke hoʻokaʻawale ʻia ka HPMC i ka papa hana, ka papa meaʻai a me ka papa lāʻau lapaʻau e like me ke kumu. I kēia manawa, ʻo ka hapa nui o nā huahana home ka pae kūkulu. I ka papa hana, hoʻohana ʻia ka pauka putty i ka nui nui, ma kahi o 90% e hoʻohana ʻia no ka pauka putty, a hoʻohana ʻia ke koena no ka mortar sima a me ke kāpili.
Pehea e hoʻokaʻawale ai i ka maikaʻi o ka HPMC maʻalahi a intuitively?
——Pane: (1) Keokeo: ʻOiai ʻaʻole hiki i ka keʻokeʻo ke hoʻoholo inā he maʻalahi ka HPMC e hoʻohana, a inā hoʻohui ʻia nā mea keʻokeʻo i ka wā o ke kaʻina hana, e hoʻopilikia ia i kona maikaʻi. Eia naʻe, ʻo ka hapa nui o nā huahana maikaʻi he keʻokeʻo maikaʻi. (2) Maikaʻi: ʻO ka maikaʻi o HPMC maʻamau he 80 mesh a me 100 mesh, a he 120 mesh ka liʻiliʻi. ʻO ka hapa nui o HPMC i hana ʻia ma Hebei he 80 mesh. ʻO ka ʻoi aku ka maikaʻi, ʻo ka ʻōlelo maʻamau, ʻoi aku ka maikaʻi. (3) Ka hoʻouna māmā: e hoʻokomo i ka hydroxypropyl methylcellulose (HPMC) i loko o ka wai e hana i kahi colloid māmā, a nānā i kāna transmittance māmā. ʻOi aku ka nui o ka transmittance māmā, ʻoi aku ka maikaʻi, e hōʻike ana he liʻiliʻi nā insolubles i loko. . ʻOi aku ka maikaʻi o ka permeability o nā reactors vertical, a ʻoi aku ka maikaʻi o nā reactors horizontal, akā ʻaʻole ia he manaʻo ʻoi aku ka maikaʻi o nā reactors vertical ma mua o nā reactors horizontal, a ua hoʻoholo ʻia ka maikaʻi o ka huahana e nā kumu he nui. (4) Kaumaha kikoʻī: ʻO ka nui o ka umekaumaha kikoʻī, ʻoi aku ka ʻoi aku ka maikaʻi. Nui ka kikoʻī, maʻamau no ka mea he kiʻekiʻe ka ʻike o ka hui hydroxypropyl i loko, a ʻoi aku ka kiʻekiʻe o ka ʻike o ka hui hydroxypropyl, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai. (5) Ke ʻā: E lawe i kahi ʻāpana liʻiliʻi o ka hāpana a hoʻā i ke ahi, a ʻo ke koena keʻokeʻo he lehu. ʻO ka mea keʻokeʻo keʻokeʻo, ʻoi aku ka maikaʻi o ka maikaʻi, a aneane ʻaʻohe koena i nā waiwai maʻemaʻe.
He aha ke kumu kūʻai o ka hydroxypropyl methylcellulose?
—–Haina; ʻO ke kumukūʻai o ka hydroxypropylmethyl e pili ana i kona maʻemaʻe a me ka lehu. ʻO ke kiʻekiʻe o ka maʻemaʻe, ʻoi aku ka liʻiliʻi o ka lehu, ʻoi aku ka kiʻekiʻe o ke kumukūʻai. A i ʻole, ʻoi aku ka haʻahaʻa o ka maʻemaʻe, ʻoi aku ka nui o ka lehu, ʻoi aku ka haʻahaʻa o ke kumukūʻai. Toni i ka 17,000 yuan no ke tona. ʻO 17,000 yuan kahi huahana maʻemaʻe me ka aneane ʻaʻohe haumia. Inā ʻoi aku ka kiʻekiʻe o ke kumukūʻai ma mua o 17,000 yuan, ua hoʻonui ʻia ka waiwai o ka mea hana. He maʻalahi ke ʻike inā maikaʻi a maikaʻi ʻole paha ka maikaʻi e like me ka nui o ka lehu i loko o ka hydroxypropyl methylcellulose.
He aha ka viscosity o ka hydroxypropyl methylcellulose i kūpono i ka pauka putty a me ka mortar?
—–Haina; ʻO ka pauka putty maʻamau he 100,000 yuan, a ʻoi aku ka kiʻekiʻe o ke koi no ka mortar, a pono ʻo 150,000 yuan e maʻalahi e hoʻohana. Eia kekahi, ʻo ka hana nui o ka hydroxypropyl methylcellulose ka mālama ʻana i ka wai, a ukali ʻia e ka mānoanoa. I ka pauka putty, ʻoiai he maikaʻi ka paʻa ʻana o ka wai a haʻahaʻa ka viscosity (70,000-80,000), hiki nō hoʻi. ʻOiaʻiʻo, ʻoi aku ka kiʻekiʻe o ka viscosity ma lalo o 100,000, a ʻoi aku ka maikaʻi o ka paʻa wai pili. Ke piʻi ka viscosity ma mua o 100,000, he hopena ka viscosity i ka mālama wai ʻAʻole nui ka hopena.
