Ke kuleana oHPMCi loko o ka mortar pulu
ʻO ka mortar hui pulu: ʻO ka mortar hui ʻia he ʻano sima, ʻāwili maikaʻi, hui ʻia a me ka wai, a e like me nā waiwai o nā ʻāpana like ʻole, ma kahi ʻāpana i koho ʻia, ma hope o ke ana ʻana ma ke kahua hui ʻana, hui ʻia, lawe ʻia i kahi i hoʻohana ʻia e ke kalaka, i loko o kahi pahu mālama i hoʻolaʻa ʻia, a hoʻohana ʻia i ka manawa i kuhikuhi ʻia no ka hui pulu i hoʻopau ʻia.
Hoʻohana ʻia ka Hydroxypropyl methyl cellulose ma ke ʻano he mea paʻa wai no ka sima sima, ka hoʻopaʻa ʻana i ka sima. I loko o ka gypsum ma ke ʻano he mea hoʻopaʻa e hoʻomaikaʻi i ka noi a hoʻolōʻihi i ka manawa hana, hydroxypropyl methylcellulose HPMC paʻa wai i ʻole e wikiwiki loa ka slurry ma hope o ka maloʻo ʻana a me ka haki ʻana, e hoʻopaʻakikī ana e hoʻomaikaʻi i ka ikaika. ʻO ka paʻa wai kahi waiwai koʻikoʻi o ka hydroxypropyl methyl cellulose HPMC, a he mea hopohopo nō hoʻi ia no nā mea hana sima pulu he nui. ʻO nā mea e hoʻopilikia ai i ka hopena paʻa wai o ka sima pulu, ʻo ia ka nui o ka HPMC i hoʻohui ʻia, ka viscosity o HPMC, ka maikaʻi o nā ʻāpana a me ka mahana o ke kaiapuni hoʻohana.
ʻO ka hana nui o ka Hydroxypropyl methyl cellulose HPMC i loko o ka mortar pulu i ʻekolu mau ʻano, ʻo ka mea mua ka maikaʻi loa o ka paʻa ʻana i ka wai, ʻo ka lua ka like ʻana o ka mortar pulu a me ka thixotropy o ka mana, ʻo ke kolu ka launa pū ʻana me ka sima. ʻO ka paʻa ʻana o ka wai o ka cellulose ether e pili ana i ka nui o ka omo wai o ke kumu, ka haku mele mortar, ka mānoanoa o ka papa mortar, ke koi wai mortar, a me ka manawa hoʻonohonoho. ʻO ke kiʻekiʻe o ka transparency o ka hydroxypropyl methyl cellulose, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai.
ʻO nā mea e hoʻopilikia ai i ka paʻa ʻana o ka wai o ka mortar pulu e komo pū me ka viscosity o ka cellulose ether, ka hoʻohui ʻana i ka nui, ka nui o ka ʻāpana a me ka mahana. ʻO ka nui o ka viscosity o ka cellulose ether, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai. ʻO ka viscosity kahi mea nui no ka hana HPMC. No ka huahana like, ʻokoʻa loa ka hoʻohana ʻana i nā ʻano hana like ʻole e ana i ka viscosity o nā hopena, ʻo kekahi ma kahi o ʻelua. No laila, pono e hoʻokō ʻia ka hoʻohālikelike viscosity ma ke ʻano hoʻāʻo like, me ka mahana, ka rotor, a pēlā aku.
Ma ke ʻano laulā, ʻo ke kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai. Eia nō naʻe, ʻo ke kiʻekiʻe o ka viscosity, ʻoi aku ke kiʻekiʻe o ke kaumaha molekala o HPMC, a ʻoi aku ka haʻahaʻa o ka solubility o HPMC, kahi hopena maikaʻi ʻole i ka ikaika a me ka hana kūkulu o ka mortar. ʻO ke kiʻekiʻe o ka viscosity, ʻoi aku ka maopopo o ka hopena mānoanoa o ka mortar, akā ʻaʻole pili pololei. ʻO ke kiʻekiʻe o ka viscosity, ʻoi aku ka pipili o ka mortar pulu, hana kūkulu maikaʻi, hana scraper viscous a me ke kiʻekiʻe o ka hoʻopili ʻana i ka substrate. Eia naʻe, ʻaʻole i kōkua ka hoʻomaikaʻi ʻana o ka ikaika kūkulu o ka mortar pulu ponoʻī. ʻO ke kūkulu ʻana, ʻaʻole maopopo ka hana anti-hanging. I ka hoʻohālikelike ʻana, ʻo kekahi viscosity waena a me ka haʻahaʻa akā ʻo ka hydroxypropyl methylcellulose i hoʻololi ʻia he hana maikaʻi loa i ka hoʻomaikaʻi ʻana i ka ikaika kūkulu o ka mortar pulu.
ʻO ka nui o ka cellulose ether PMC wet mortar i hoʻohui ʻia, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai, ʻoi aku ke kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai. ʻO ka fineness kekahi helu hana koʻikoʻi o ka hydroxypropyl methyl cellulose.
Loaʻa i ka maikaʻi o ka hydroxypropyl methyl cellulose kahi mana i kona paʻa ʻana i ka wai. Ma lalo o nā kūlana maʻamau, ʻo ka viscosity like a me ka fineness ʻokoʻa o ka hydroxypropyl methyl cellulose, ma lalo o ka nui like o ka hoʻohui, ʻoi aku ka liʻiliʻi o ka fineness o ka hopena paʻa wai.
I loko o ka mortar pulu, ka hoʻohui ʻana o ka cellulose etherHPMChe haʻahaʻa loa ia, akā hiki iā ia ke hoʻomaikaʻi nui i ka hana kūkulu ʻana o ka mortar pulu, ʻo ia ka mea hoʻohui nui e hoʻopilikia nui i ka hana o ka mortar. Hoʻopilikia nui ʻia ka hana o ka mortar pulu e ke koho kūpono o ka hydroxypropyl methyl cellulose
