ʻO ke kuleana o ka hydroxypropyl methyl cellulose i ka mortar pulu

ʻO ke kuleana o ka HPMC i ka mortar pulu

Wet mix mortar: Mixed mortar is a kind of cement, fine aggregate, admixture a me ka wai, a e like me ka waiwai o na mea like ole, ma kekahi mahele, ma hope o ke ana ana ma ke kahua hui, huikau, laweia i kahi i hoohanaia e ka kalaka, i loko o kahi pahu mālama i hoʻolaʻa ʻia, a hoʻohana ʻia i ka manawa i ʻōlelo ʻia i ka hui ʻana i hoʻopau ʻia.

Hoʻohana ʻia ʻo Hydroxypropyl methyl cellulose ma ke ʻano he mea mālama wai no ka mortar sima, retarder mortar pumping.I ka gypsum e like me ka binder e hoʻomaikaʻi i ka noi a hoʻolōʻihi i ka manawa hana, hydroxypropyl methylcellulose HPMC ka paʻa wai i hiki ʻole i ka slurry ma hope o ka hoʻomaloʻo ʻana ʻaʻole wikiwiki loa a māwae, paʻakikī e hoʻomaikaʻi i ka ikaika.He waiwai koʻikoʻi ka paʻa ʻana o ka wai o ka HPMC hydroxypropyl methyl cellulose, a ʻo ia hoʻi ka mea e hopohopo nei i ka nui o nā mea hana pahū wai.ʻO nā mea e pili ana i ka hopena paʻa wai o ka mortar pulu ʻo ia ka nui o ka HPMC i hoʻohui ʻia, ka viscosity o ka HPMC, ka maikaʻi o nā ʻāpana a me ka mahana o ke kaiapuni hoʻohana.
ʻO Hydroxypropyl methyl cellulose HPMC i loko o ka mortar pulu ka hana nui i ʻekolu mau ʻaoʻao, ʻo ka mea maikaʻi loa ka paʻa ʻana o ka wai, ʻo ka lua ka paʻa ʻana o ka mortar a me ka thixotropy o ka mana, ʻo ke kolu ka pilina me ka sima.ʻO ka paʻa ʻana o ka wai cellulose ether e pili ana i ka nui o ka hoʻoheheʻe ʻana o ka wai o ke kumu, ka hoʻokumu ʻana i ka mortar mortar, ka mānoanoa o ka mortar layer, ka koi wai mortar, ka manawa hoʻonohonoho.ʻOi aku ka kiʻekiʻe o ke aniani o ka hydroxypropyl methyl cellulose, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai.
ʻO nā mea e pili ana i ka paʻa ʻana o ka wai o ka mortar pulu ʻo ia ka viscosity o cellulose ether, ka hoʻohui ʻana i ka nui, ka nui a me ka mahana.ʻOi aku ka nui o ka viscosity o cellulose ether, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai.He mea nui ka viscosity no ka hana HPMC.No ka huahana like, me ka hoʻohana ʻana i nā ʻano hana like ʻole e ana i ka viscosity o nā hopena i ʻokoʻa like ʻole, ʻo kekahi ma ka helu ʻelua.No laila, pono e hana ʻia ka hoʻohālikelike viscosity i ke ʻano hoʻāʻo like, me ka mahana, rotor, etc.

ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai.Eia naʻe, ʻoi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka kiʻekiʻe o ka molecular paona o HPMC, a me ka haʻahaʻa o ka solubility o HPMC, kahi hopena maikaʻi ʻole i ka ikaika a me ka hana ʻana o ka mortar.ʻO ke kiʻekiʻe o ka viscosity, ʻoi aku ka maopopo o ka hopena mānoanoa o ka mortar, akā ʻaʻole pili pono.ʻOi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka paʻa o ka mortar pulu, ka hana hana maikaʻi, ka hana scraper viscous a me ka hoʻopili kiʻekiʻe i ka substrate.Eia naʻe, ʻaʻole i kōkua ka hoʻomaikaʻi ʻana i ka ikaika o ke kūkulu ʻana o ka mortar pulu ponoʻī.ʻO ke kūkulu ʻana ʻelua, ʻaʻole maopopo ka hana anti - kau ʻana i ka hana.ʻO ka ʻokoʻa, ʻoi aku ka maikaʻi o ka hoʻomaikaʻi ʻana i ka ikaika o ke kūkulu ʻana o ka mortar pulu.
ʻOi aku 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 ka kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai.ʻO ka maikaʻi kekahi ʻōlelo kuhikuhi hana nui o ka hydroxypropyl methyl cellulose.
ʻO ka maikaʻi o ka hydroxypropyl methyl cellulose kekahi mana i kona paʻa wai.Ma lalo o nā kūlana maʻamau, ʻo ka viscosity like a me ka fineness like ʻole o ka hydroxypropyl methyl cellulose, ma lalo o ka nui o ka hoʻohui, ʻoi aku ka liʻiliʻi o ka fineness o ka hopena paʻa wai.
I loko o ka pulu pulu, ka hoʻohui o cellulose ether HPMC he haʻahaʻa loa, akā hiki iā ia ke hoʻomaikaʻi maikaʻi i ka hana o ke kūkulu ʻana i ka mortar pulu, ʻo ia ka mea hoʻohui nui e pili ana i ka hana o ka mortar.Hoʻopili nui ʻia ka hana ʻana o ka mortar pulu e ke koho kūpono o ka hydroxypropyl methyl cellulose.
