Hoʻohana nui ʻia ʻo Starch ether i ke kūkulu ʻana i ka mortar, hiki ke hoʻopili i ke kūlike o ka mortar e pili ana i ka gypsum, ka sima a me ka lime, a hoʻololi i ke kūkulu ʻana a me ke kū ʻana o ka mortar.Hoʻohana pinepine ʻia nā ethers starch me nā cellulose ethers i hoʻololi ʻole ʻia a hoʻololi ʻia.He kūpono ia no nā ʻōnaehana kūʻokoʻa a me ka alkaline, a kūpono me ka hapa nui o nā mea hoʻohui i ka gypsum a me nā huahana sima (e like me nā surfactants, MC, starch a me polyvinyl acetate a me nā polymers hiki ke hoʻoheheʻe wai).
Nā hiʻohiʻona nui:
(1) Hoʻohana pinepine ʻia ka starch ether me ka methyl cellulose ether, e hōʻike ana i kahi hopena synergistic maikaʻi ma waena o nā mea ʻelua.ʻO ka hoʻohui ʻana i ka nui kūpono o ka starch ether i ka methyl cellulose ether hiki ke hoʻomaikaʻi maikaʻi i ke kūpaʻa sag a me ke kūpaʻa paheʻe o ka mortar, me ka waiwai kiʻekiʻe.
(2) ʻO ka hoʻohui ʻana i ka nui kūpono o ka starch ether i ka mortar i loaʻa i ka methyl cellulose ether hiki ke hoʻonui nui i ka paʻa ʻana o ka pahū a hoʻomaikaʻi i ka wai, e ʻoi aku ka maʻalahi o ke kūkulu ʻana a me ka ʻōpala.
(3) ʻO ka hoʻohui ʻana i ka nui kūpono o ka starch ether i ka mortar i loaʻa i ka methyl cellulose ether hiki ke hoʻonui i ka paʻa ʻana o ka wai o ka pahu a hoʻolōʻihi i ka manawa wehe.
(4) ʻO ka starch ether kahi mea hoʻololi kemika starch ether i hiki ke hoʻoheheʻe ʻia i ka wai, kūpono me nā mea hoʻohui ʻē aʻe i loko o ka lepo maloʻo maloʻo, hoʻohana nui ʻia i nā tile adhesives, hoʻoponopono mortar, plaster plaster, loko a me waho pā putty, gypsum-based embedded Joints and filling materials .
ʻO nā hiʻohiʻona o ka starch ether ka mea nui: (a) hoʻomaikaʻi i ka pale ʻana i ka sag;(b) hoʻomaikaʻi i ka hana;(c) ka hoʻomaikaʻi ʻana i ka nui o ka mālama ʻana i ka wai o ka palaki.
Laulā o ka hoʻohana:
He kūpono ka starch ether no nā ʻano like ʻole (cement, gypsum, lime-calcium) i loko a me waho o ka pā pāpaʻi putty, a me nā ʻano ʻano like ʻole o ka mortar a me ka hamo.
Hiki ke hoʻohana ʻia e like me ka admixture no nā huahana ciment-based, nā huahana gypsum-based a me nā huahana lime-calcium.Hiki i ka Starch ether ke kūpono me nā mea hana a me nā mea hoʻohui ʻē aʻe;kūpono loa ia no ke kūkulu ʻana i nā hui maloʻo e like me ka mortar, adhesives, plastering and rolling materials.Hoʻohana pū ʻia nā ethers starch a me ka methyl cellulose ethers (Tylose MC grades) i ke kūkulu ʻana i nā hui maloʻo e hāʻawi i ka mānoanoa kiʻekiʻe, ka ʻoi aku ka ikaika, ka pale ʻana a me ka maʻalahi o ka lawelawe ʻana.Hiki ke hoemiia ka viscosity o na morta, adhesives, plasters and roll renders i loa'a ka methyl cellulose ethers ma o ka hoohui ana i ka starch ethers.
