ʻO ka Hydroxypropyl methylcellulose (HPMC) he mau cellulose ethers i loaʻa nā pūʻulu hydroxyl ma ke kaulahao cellulose i pani ʻia no kahi hui methoxy a hydroxypropyl paha.It hana ʻia e ka etherification kūikawā o ka pulupulu maʻemaʻe loa ma lalo o nā kūlana alkaline. I nā makahiki i hala iho nei, ʻo HPMC, ma ke ʻano he hoʻohui hana, ke pāʻani nui neisi ka paʻa ʻana o ka wai a me ka mānoanoa i ka ʻoihana kūkulu hale a hoʻohana nui ʻia idrymix mortars, like tile adhesive, grouts, plastering, wall putty, self leveling, insulation mortar a pela aku.
ʻO ka maʻamau, no ka pauka putty, ka viscosity oHPMClawa ma kahi o 70,000 a 80,000. ʻO ka manaʻo nui ma kāna hana mālama wai, ʻoiai he liʻiliʻi ka hopena mānoanoa. No ka mortar, nā koi noHPMCʻoi aku ka kiʻekiʻe, a pono ka viscosity ma kahi o 150,000, hiki ke hōʻoia i ka hana ʻoi aku ka maikaʻi ma ka mortar sima. ʻOiaʻiʻo, i ka pauka putty, ʻoiai ʻoi aku ka maikaʻi o ka hana paʻa wai o HPMC, ʻoiai inā he haʻahaʻa ka viscosity (70,000 a 80,000), ʻae ʻia. Eia nō naʻe, i loko o ka pahu sima, ʻoi aku ka maikaʻi o ke koho ʻana i ka HPMC me kahi viscosity nui (ʻoi aku ma mua o 100,000), no ka mea, ʻoi aku ka nui o kona hopena paʻa wai i kēia kūlana.
ʻO ka pilikia o ka wehe ʻana i ka pauka putty e hilinaʻi nui ʻia i ka maikaʻi o ka calcium hydroxide a ʻaʻohe mea liʻiliʻi me HPMC. Inā he haʻahaʻa ka helu calcium o ka calcium hydroxide a i ʻole kūpono ʻole ka ratio o CaO a me Ca(OH)2, hiki ke hāʻule ka pauda putty. E pili ana i ka hopena o ka HPMC, ʻike nui ʻia i kāna hana mālama wai. Inā maikaʻi ʻole ka hana paʻa ʻana o ka wai o ka HPMC, hiki ke loaʻa kekahi hopena i ka depowdering o ka pauka putty.
He haʻahaʻa loa nā koi no ka hoʻohana ʻana i ka pauka putty. Ua lawa ka viscosity o 100,000. ʻO ka mea nui ka loaʻa ʻana o nā waiwai mālama wai maikaʻi. Ma ke ʻano o ka mortar, ʻoi aku ka kiʻekiʻe o nā koi a koi ʻia ka viscosity kiʻekiʻe, a ʻoi aku ka maikaʻi o ka huahana 150,000.
(1) ʻOihana hana: Ma ke ʻano he mea hoʻopaʻa wai a me ka hoʻopaneʻe ʻana i ka mīkini sima, hana ia i ka mortar pumpable. E hoʻohana i ka plaster, gypsum, putty pauka a i ʻole nā mea kūkulu hale ʻē aʻe e like me nā mea hoʻopili e hoʻomaikaʻi ai i ka hoʻohana ʻana a hoʻolōʻihi i ka manawa hana.
