ʻO ke kuleana o ka starch ether i ka mortar

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 nui 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; He 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.
