He aha ka Starch Etera?

Starka eteraHoʻohana nui ʻia i ka mīkini hana, hiki ke hoʻopili i ka 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 cement (e like me nā surfactants, MC, starch a me nā polymers wai-soluble e like me polyvinyl acetate).

ʻO ka hana nui

(1) Hiki i ka mānoanoa wikiwiki maikaʻi: ka viscosity waena, ka paʻa wai kiʻekiʻe;

(2) He liʻiliʻi ke ʻano, a he hopena maikaʻi ka hopena haʻahaʻa;

(3) E hoʻomaikaʻi i ka hiki anti-sag o ka mea pono'ī;

(4) Loaʻa iā ia ka lubricity maikaʻi, hiki ke hoʻomaikaʻi i ka hana hana o ka mea a hoʻomaʻamaʻa i ka hana.

Main hiʻona

Aia nā hiʻohiʻona o ka starch ether i loko o:

(a) Hoʻomaikaʻi i ka pale sag;

(b) Hoʻomaikaʻi i ke kūkulu ʻana;

(c) E hoʻomaikaʻi i ka nui o ka mālama ʻana i ka wai o ka palaki.

ʻO ka hui ʻana

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. ʻOi aku ka waiwai o ka hua.

I loko o ka mortar i loaʻa ka methyl cellulose ether, hiki i ka hoʻohui ʻana i kahi nui kūpono o ka starch 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 ʻoi aku ka maʻalahi o ka ʻōpala.

I loko o ka mortar i loaʻa ka methyl cellulose ether, hiki ke hoʻonui i ka nui o ka starch ether e hoʻonui i ka paʻa ʻana o ka wai a hoʻolōʻihi i ka manawa wehe.

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 i ka mortar, plaster plaster, loko a me waho o ka paia putty, gypsum-based caulking a me ka hoʻopiha ʻana i nā mea, nā mea hoʻopili, pā pōhaku lepo.

He kūpono ka starch ether no nā ʻano like ʻole (cement, gypsum, lime calcium-based) o loko a me waho o ka pā pā, a me nā ʻano like ʻole o ka mortar plastering mortar.

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 ia no ke kūkulu ʻana i nā hui maloʻo e like me ka mortar, adhesives, plastering and rolling materials. Starch ether a me methyl cellulose ether (KimaCellMC grade) hoʻohana pū ʻia i ke kūkulu ʻana i nā hui maloʻo e hāʻawi i ka mānoanoa kiʻekiʻe, ʻoi aku ka ikaika o ke ʻano, 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.
