ʻO ka mortar wet-mixed he sima, hui maikaʻi, admixture, wai a me nā mea like ʻole i hoʻoholo ʻia e like me ka hana.Wahi a kekahi hapa, ma hope o ke ana ʻana a hui ʻia i loko o ke kahua hui, lawe ʻia ia i kahi o ka hoʻohana ʻana e kahi kaʻa mixer, a hoʻokomo ʻia i kahi kūikawā.
Hoʻohana ʻia ʻo Hydroxypropyl methylcellulose ma ke ʻano he mea hoʻopaʻa wai a me ka hoʻopaneʻe ʻana i ka momi sima e hana ai i ka mortar pumpable.Hoʻohana ʻia ma ke ʻano he mea hoʻopili i ka plastering plaster, hoʻomaikaʻi ia i ka pālahalaha a hoʻolōʻihi i ka manawa hana.ʻO ka hana paʻa wai o ka hydroxypropyl methylcellulose HPMC e pale i ka slurry mai ka haki ʻana ma muli o ka maloʻo wikiwiki ʻana ma hope o ka noi ʻana, a hoʻonui i ka ikaika ma hope o ka paʻakikī.He hana koʻikoʻi ka paʻa ʻana o ka wai no ka HPMC hydroxypropyl methylcellulose, a he hana hoʻi ia e nānā ʻia ai e ka nui o nā mea hana mokomoko wai.ʻO nā mea e pili ana i ka hopena paʻa wai o ka mortar i hui pū ʻia me ka nui o ka HPMC i hoʻohui ʻia, ka viscosity o HPMC, ka maikaʻi o nā ʻāpana, a me ka mahana o ka hoʻohana ʻana.
ʻO ka hana koʻikoʻi o ka hydroxypropyl methylcellulose HPMC i loko o ka wet-mix mortar he ʻekolu mau ʻano, ʻo ka mea maikaʻi loa ka mālama ʻana i ka wai, ʻo ka mea ʻē aʻe ka mana i ka kūlike a me ka thixotropy o ka wet-mix mortar, a ʻo ke kolu ka pilina me ka sima.ʻO ka hopena paʻa wai o ka cellulose ether e pili ana i ka hoʻopili ʻana o ka wai o ka papa kumu, ka hoʻohui ʻana o ka mortar, ka mānoanoa o ka mortar layer, ke koi wai o ka mortar, a me ka manawa hoʻonohonoho o ka mea hoʻonohonoho.ʻOi aku ka kiʻekiʻe o ke aniani o ka hydroxypropyl methylcellulose, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai.
ʻO nā mea e pili ana i ka paʻa ʻana o ka wai o ka mortar hui pū me ka cellulose ether viscosity, ka nui o ka hoʻohui ʻana, ka maikaʻi o ka ʻāpana a me ka mahana hoʻohana.ʻOi aku ka nui o ka viscosity o cellulose ether, ʻoi aku ka maikaʻi o ka hana paʻa wai.ʻO ka viscosity kahi mea koʻikoʻi o ka hana HPMC.No ka huahana like, ʻokoʻa loa nā hopena viscosity i ana ʻia e nā ʻano hana like ʻole, a ua pālua ʻia kekahi.No laila, i ka hoʻohālikelike ʻana i ka viscosity, pono e hana ʻia ma waena o nā ʻano hoʻokolohua like, me ka mahana, rotor, etc.
ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka hopena paʻa wai.Eia nō naʻe, ʻoi aku ka kiʻekiʻe o ka viscosity a me ke kiʻekiʻe o ke kaumaha molekala o HPMC, ʻo ka emi ʻana o kona solubility e loaʻa i ka hopena maikaʻi ʻole i ka ikaika a me ka hana ʻana o ka mīkini.ʻO ke kiʻekiʻe o ka viscosity, ʻoi aku ka maopopo o ka hopena mānoanoa ma ka mortar, akā ʻaʻole pololei ia.ʻO ke kiʻekiʻe o ka viscosity, ʻoi aku ka viscous o ka mortar pulu, ʻo ia hoʻi, i ka wā o ke kūkulu ʻana, ʻike ʻia ʻo ia e pili ana i ka scraper a me ka hoʻopili kiʻekiʻe i ka substrate.Akā ʻaʻole kōkua ka hoʻonui ʻana i ka ikaika o ke kūkulu ʻana o ka mortar pulu ponoʻī.I ka wā o ke kūkulu ʻana, ʻaʻole maopopo ka hana anti-sag.ʻO ka mea ʻē aʻe, ʻo kekahi hydroxypropyl methylcellulose i hoʻololi ʻia me ka liʻiliʻi a me ka viscosity haʻahaʻa he hana maikaʻi loa i ka hoʻomaikaʻi ʻana i ka ikaika o ke kūkulu ʻana o ka mortar pulu.
ʻOi aku ka nui o ka cellulose ether HPMC i hoʻohui ʻia i loko o ka mortar i hui pū ʻia, ʻoi aku ka maikaʻi o ka hana paʻa wai, a ʻoi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka hana paʻa wai.ʻO ka maikaʻi kekahi ʻōlelo kuhikuhi hana nui o ka hydroxypropyl methylcellulose.
ʻO ka maikaʻi o ka hydroxypropyl methylcellulose kekahi hopena i kona paʻa wai.ʻO ka mea maʻamau, no ka hydroxypropyl methylcellulose me ka like viscosity akā ʻokoʻa ka fineness, ʻoi aku ka maikaʻi o ka ʻoi aku ka maikaʻi ʻO ka hopena paʻa wai ʻoi aku ka maikaʻi.
I loko o ka pulu pulu, ka hoʻohui nui o cellulose etera HPMC he haʻahaʻa loa, akā hiki iā ia ke hoʻomaikaʻi maikaʻi i ka hana o ke kūkulu ʻia ʻana o ka mīkini i hoʻohui ʻia, a he mea hoʻohui nui ia e pili ana i ka hana hana o ka mīkini.ʻO ke koho kūpono o ka hydroxypropyl methylcellulose kūpono ka mana nui i ka hoʻomaikaʻi ʻana i ka hana ʻana o ka hamo-hui ʻia.
