1. Nā hola wehe
Ke noho pū nei ka pauda lāʻau a me ka cellulose etera i loko o ka mortar pulu, hōʻike kekahi mau hiʻohiʻona ʻikepili i ʻoi aku ka ikaika o ka ikehu kinetic e hoʻopili ai i nā huahana hydration cement, a ʻoi aku ka nui o ka cellulose ether i loko o ka wai interstitial, kahi e hoʻopili ai i ka viscosity Mortar a me ka manawa hoʻonohonoho.ʻOi aku ka nui o ka ʻili o ka cellulose etera ma mua o ka pauka lāʻau, a ʻoi aku ka nui o ka cellulose etera i hoʻonui ʻia ma ka pānaehana mortar e pōmaikaʻi i ka hoʻokumu ʻana i nā paʻa hydrogen ma waena o ka ʻili kumu a me ka cellulose etera.
I loko o ka mortar pulu, evaporates ka wai i loko o ka mortar, a hoʻonuiʻia ka cellulose ether ma luna o kaʻili, a e hanaʻia kahi kiʻiʻoniʻoni ma luna o ka ili o ka pahū i loko o 5 mau minuke, e hoʻemi ana i ka helu evaporation ma hope, no ka mea, nui ka wai. wehe 'ia mai ka mānoanoa manoanoa hapa o ia e neʻe aku i ka thinner mortar papa, a me ka kiʻiʻoniʻoni i hanaia ma ka hoʻomaka 'ana i hapa hoʻoheheʻe, a me ka neʻeʻana o ka wai e lawe hou cellulose etera enrichment ma luna o ka mortar ili.
ʻO ka hana kiʻiʻoniʻoni o cellulose ether ma ka ʻili o ka mortar he mana nui i ka hana o ka mortar:
1. ʻO ke kiʻiʻoniʻoni i hanaʻia he lahilahi loa a e hoʻoheheʻeʻia iʻelua manawa, hikiʻole ke kaupalena i ka hoʻoheheʻeʻana o ka wai a hoʻemi i ka ikaika.
2. ʻO ke kiʻiʻoniʻoni i hanaʻia he mānoanoa loa.He kiʻekiʻe ka manaʻo o ka cellulose ether i loko o ka wai interstitial mortar a kiʻekiʻe ka viscosity.ʻAʻole maʻalahi ka haki ʻana i ke kiʻiʻoniʻoni i ka wā e paʻi ʻia ai nā tile.
Hiki keʻikeʻia heʻoi aku ka nui o ka hopena o nā mea hana kiʻiʻoniʻoni o cellulose ether i ka manawa wehe.ʻO keʻano o ka cellulose ether (HPMC, HEMC, MC, a me nā mea'ē aʻe) a me ka degere o ka etherification (substitution degree) pili pono i nā mea hana kiʻiʻoniʻoni o cellulose ether, a me ka paʻakikī a me ka paʻakikī o ke kiʻi.
