Cellulose ethers, ʻoi aku hoʻi nā hypromellose ethers, nā mea nui o nā morta kalepa.No ka cellulose ether, ʻo kona viscosity kahi kuhikuhi koʻikoʻi o nā ʻoihana hana mortar, ua aneane lilo ka viscosity kiʻekiʻe i ke koi kumu o ka ʻoihana mortar.Ma muli o ka mana o ka ʻenehana, kaʻina hana a me nā mea hana, paʻakikī ke hōʻoia i ka viscosity kiʻekiʻe o ka homecellulose eteranā huahana no ka manawa lōʻihi.Hoʻohana ʻia ʻo Cellulose ether ma ke ʻano he mea mālama wai, mānoanoa a me ka mea hoʻopaʻa i nā huahana mortar, he hopena nui i ka hana hana, viscosity pulu, manawa hana a me ke ʻano hana o ka ʻōnaehana mortar.Hoʻokō nui ʻia kēia mau hana e ka paʻa hydrogen ma waena o ka mole mole eter cellulose a me ka mole wai a me ka hana wiliwili o cellulose ether mole, ʻoiaʻiʻo, lawe ia i kahi ʻāpana o ka paʻa hydrogen i loko o ke kaulahao molekula cellulose ether a hoʻonāwaliwali i ka entanglement o cellulose ether, ka mea e hoʻonāwaliwali ai i ka paʻa ʻana o ka wai a me ka hiki ke hoʻomaʻemaʻe i ka cellulose ether.ʻAʻole manaʻo ka poʻe hana mortar i kēia wahi, ma ka ʻaoʻao hoʻokahi, ʻoi aku ka paʻakikī o nā huahana mortar home, ʻaʻole naʻe i makaʻala e hoʻolohe i ke ʻano o ka hana hana, ma kekahi ʻaoʻao, koho mākou i ka viscosity ʻoi aku ka kiʻekiʻe. ma mua o ka ʻenehana koi viscosity, ua uku ʻia kēia ʻāpana no ka nalowale o ka paʻa ʻana o ka wai, akā i ka wettability ua pōʻino.
Hoʻopili ʻia ka hana ʻana o ka mortar e ka cellulose ether i loaʻa i ka mea hoʻopili adhesive i ke kaʻina hana, i loko o kēia pepa, ua hōʻoia ʻia ka ʻokoʻa o ka ikaika tensile adhesive ma waena o ka huahana cellulose a me ka huahana cellulose ether i hoʻohui ʻia me ka tackifier i loko o ka mea hoʻopili seramika.ʻO Tackifier kahi ʻano mea i hoʻohui ʻia e kekahi mau mea hana cellulose ether i mea e hoʻopau ai i ka hemahema o ka ʻenehana hana, ʻenehana a me nā mea hana.ʻO ka noho ʻana o ka tackifier e hana ai i nā molekole kaulahao lōʻihi o cellulose ether cross-link a lilo i ʻupena-like, e pili ana i ka wikiwiki o ka hoʻokumu ʻana o ka cellulose ether film a me ke kūlana o ke kiʻiʻoniʻoni, no laila e pili ana i ke kuleana o ka cellulose ether i loko o ka mortar, ka pololei- ʻO ka mana o ka nānā ʻana ʻo ia: ua loli ka ikaika tensile adhesive ma lalo o kēlā me kēia kūlana hoʻōla;ua hooloihiia ka manawa hoomoe o ka hamo.
1. Ma lalo o ke kūlana ho'ōla maʻamau, ʻo ka hoʻohui ʻana o ka tackifier a me ka cellulose ether me ka ʻole o ka tackifier i ke kaʻina hana i kekahi hopena i ka ikaika tensile adhesive o ka ceramic tile adhesive, nā huahana i hoʻohui ʻia me ka tackifier i ke kaʻina hana he kiʻekiʻe kiʻekiʻe ka ikaika tensile adhesive. .
2. Ma ke ʻano o ka pale wai, ʻoi aku ka maikaʻi o ka tensile adhesive ikaika o ka ceramic tile adhesive me ka cellulose ether i hoʻohui ʻia i ka tackifier i loko o ke kaʻina hana i ʻoi aku ka hewa ma mua o ka huahana me ka ʻole o ka tackifier i ke kaʻina hana maʻamau, ʻo ka cellulose ether i loaʻa i ka tackifier pili i ka wai. kū'ē i ka paʻa tile.
3.Ma ke ʻano o ka manawa hoʻonohonoho ea,cellulose eterame ka tackifier i hoʻohana ʻia i ka tile adhesive, ʻoi aku ka haʻahaʻa o kona ikaika tensile adhesive ma mua o ka huahana me ka ʻole o ka tackifier, a ua pōkole ka manawa wehe.
4. No ka hoʻonohonoho ʻana i ka manawa, ʻoi aku ka wikiwiki o ka hoʻōla ʻana o ka cellulose ether ceramic tile adhesive me ka ʻole o ka hoʻohui ʻana i ka tackifier ma lalo o ke kaʻina hana maʻamau.I ka hōʻuluʻulu ʻana, ʻo ka hiki ʻana o kahi tackifier, ʻo ka hana cross-linking e hana ai ka cellulose ether aqueous solution i kahi kiʻekiʻe steric hindrance, i hōʻike ʻia ʻoi aku ka kiʻekiʻe o ka hoʻāʻo, akā ʻo ke ʻano o ka tackifier e pili ana i nā waiwai noi nui o cellulose. ether, e like me ke kūpaʻa wai, ka manawa wehe, wettability a pēlā aku.ʻO kaʻoiaʻiʻo,ʻo ka viscosity kahi wale nō o nā kuhikuhina hana o ka cellulose ether,ʻaʻoleʻo ka viscosity he kuhikuhi koʻikoʻi no ka hana piha o ka cellulose ether, akāʻo keʻano a me nā mea o nā hui e pono ke nānā i nā mea hana mortar.
5. ʻO ia hoʻi no ka nānā nui ʻana o nā mea hana mortar i ka viscosity, e koi ana i kekahi mau ʻoihana hana cellulose ether e hoʻonui i ka viscosity ma o nā mea hou aku e hoʻokō ai i nā koi o nā mea hana mortar, a ʻo kēia ʻano huahana wale nō ka viscosity kiʻekiʻe. ʻO ka hana kūpono i ka nānā ʻana o nā mea hoʻohana, a ʻo ka viscosity kiʻekiʻe i ʻike ʻia e ka hoʻonui ʻana i ka viscosity ʻaʻole hiki ke hoʻokō i ke kumumanaʻo "High viscosity haʻahaʻa haʻahaʻa" i manaʻo ʻia e nā mea hana mortar, akā ʻaʻole i ʻoiaʻiʻo.I mea e koho ai i ka cellulose ether, he mea waiwai nui ia i loko o ka mortar, pono e ʻike nā ʻoihana mortar e ʻimi nei i ka maikaʻi kiʻekiʻe a paʻa i kekahi mau ʻike ma hope, e kōkua kēia i nā mea hana e hoʻomohala i nā huahana kiʻekiʻe, e hōʻoia i ka paʻa o ka huahana.
