ʻO ke kuleana o ka hydroxypropyl methyl cellulose i ka mortar

Hydroxypropyl methyl cellulose i loko o ka mortar maloʻo, cellulose ether hoʻohui he haʻahaʻa loa, akā hiki ke hoʻomaikaʻi maikaʻi i ka hana o ka mortar pulu, ʻo ka hana ʻana o ka mortar kekahi o nā mea hoʻohui nui.I kēia manawa, ʻo ka hydroxypropyl methyl cellulose i hoʻohana ʻia i ka mortar cellulose ether ka nui o ka hydroxypropyl methyl cellulose ether (HPMC).ʻO ka Hydroxypropyl methyl cellulose i loko o ka mortar maloʻo HPMC ka mea nui i ka mālama ʻana i ka wai, ka mānoanoa, ka hoʻomaikaʻi ʻana i ka hana o ke kūkulu ʻana.ʻAʻole komo ʻo Hydroxypropyl methylcellulose HPMC i kekahi hopena kemika, pāʻani wale i kahi hana kōkua.ʻO ka pauka Putty i hoʻohui ʻia i ka wai, ma ka paia, he hopena kemika, no ka mea aia ka hana o nā mea hou, ʻo ka pauda putty ma ka paia mai lalo mai ka paia, lepo i ka pauka, a laila hoʻohana ʻia, ʻaʻole ia, no ka mea, ua hana ʻia he mea hou (calcium carbonate).ʻO nā mea nui o ka pauka calcium hina: Ca(OH)2, CaO a me kahi liʻiliʻi o ka hui ʻana o CaCO3, CaO+H2O=Ca(OH)2 – Ca(OH)2+CO2=CaCO3↓+H2O calcium lehu i loko o ka wai. a me ka ea ma lalo o ka hana o CO2, ka hookumu ana o ka calcium carbonate, a me ka HPMC wale ka wai paʻa, auxiliary calcium lehu maikaʻi pane, kona iho 'aʻole i komo i kekahi pane.
 
High quality o hydroxypropyl methyl cellulose hiki uniformly a me ka pono e hoʻopuehu i loko o ka sima a me ka plaster huahana, a puʻupuʻu a pau paʻa particles, a hana i ka papa o ka wetting kiʻiʻoniʻoni, ka makū i loko o ke kumu no ka manawa lōʻihi hoʻokuʻu mālie, a inorganic cementitious mea hydration hopena. , i mea e hōʻoia ai i ka ikaika pili a me ka ikaika compressive o nā mea.No laila, i ke kūkulu ʻana i ke kauwela kiʻekiʻe, i mea e hoʻokō ai i ka hopena paʻa wai, pono e hoʻohui i nā huahana HPMC kiʻekiʻe e like me ke ʻano, inā ʻaʻole, e maloʻo wikiwiki a ma muli o ka lawa ʻole o ka hydration, ka hoʻohaʻahaʻa ikaika, ka haki ʻana, nele. pahu a hāʻule a me nā pilikia maikaʻi ʻē aʻe, akā hoʻonui pū i ka paʻakikī o ka hana ʻana o nā limahana.I ka emi ʻana o ka mahana, hiki ke hoʻemi ʻia ka nui o ka wai i hoʻohui ʻia e HPMC, a hiki ke hoʻokō ʻia ka hopena paʻa wai like.
