ʻO ka HPMC kahi mea hoʻohui hypromellose maʻamau i loko o ka hamo maloʻo. He kuleana koʻikoʻi ka cellulose ether i ka mortar maloʻo, ma muli o ka hana o ka ʻili, ua hoʻolaha maikaʻi ʻia ka mea cementitious i loko o ka ʻōnaehana, a ʻo ka cellulose ether he colloid pale, ka "Enveloping" o nā ʻāpana paʻa a me ka hoʻokumu ʻana o kahi lubricant. ʻO ke kiʻiʻoniʻoni ma ko lākou ʻili waho e hoʻoikaika i ka ʻōnaehana mortar, a hoʻomaikaʻi pū i ka wai o ka mortar i ke kaʻina hui ʻana a me ka maʻalahi o ke kūkulu ʻana. ʻO ka HPMC hypromellose ka mālama ʻana i ka wai, e pale ana i ka makū mai ka hoʻomaka ʻana a i ʻole e komo ʻia e ka papa kumu, e hōʻoiaʻiʻo ana ua hoʻomaʻemaʻe piha ʻia ka sima, a me nā ʻano mechanical o ka mortar, ʻo ia ka mea e pono ai no nā mortar lahilahi a me ka wai- nā papa kumu hoʻoheheʻe, a i ʻole nā morta i kūkulu ʻia ma lalo o nā kūlana maloʻo kiʻekiʻe. Hiki i ka hopena paʻa wai o hypromellose ke hoʻololi i nā ʻenehana hana kuʻuna a hoʻomaikaʻi i ka papa hana. No ka laʻana, hiki ke hana ʻia ka plastering ma luna o nā substrate absorbent me ka ʻole o ka hoʻomaʻemaʻe ʻana. ʻO ka viscosity, content, ambient temperature and molecular structure of hypromellose HPMC he hopena koʻikoʻi i kona paʻa wai. Ma lalo o nā kūlana like, ʻoi aku ka kiʻekiʻe o ka viscosity o cellulose ether, ʻoi aku ka maikaʻi o ka paʻa wai. ʻOi aku ka kiʻekiʻe o ka cellulose ether, ʻoi aku ka maikaʻi o ka paʻa wai. Ke hiki aku ka maʻiʻo o ka cellulose ether i kekahi degere, piʻi mālie ka mana paʻa wai. Me ka piʻi ʻana o ka mahana o ke kaiapuni, e emi mau ana ka mana paʻa wai o ka cellulose ether, akā ʻoi aku ka maikaʻi o kekahi mau cellulose ethers i hoʻololi ʻia i ka wai paʻa i ka wela kiʻekiʻe. ʻOi aku ka maikaʻi o ka paʻa wai o nā cellulose ethers me ka haʻahaʻa haʻahaʻa. Hiki i kā mākou hui ke hāʻawi i kahi ʻano hoʻopaʻa wai hypromellose HPMC e hoʻoponopono i ka hana paʻa wai cellulose ether i kēia manawa ʻaʻole kūpono.
