He aha nā waiwai o ka methyl cellulose ether?
Pane: He wahi liʻiliʻi wale nō o ka methyl cellulose ether i hoʻohui ʻia, a e hoʻomaikaʻi nui ʻia ka hana kikoʻī o ka gypsum mortar.
(1) Hoʻoponopono i ke kūlike
Hoʻohana ʻia ʻo Methyl cellulose ether ma ke ʻano he mānoanoa e hoʻoponopono i ke kūlike o ka ʻōnaehana.
(2) Hoʻoponopono i ka makemake wai
I loko o ka ʻōnaehana gypsum mortar, ʻo ke koi wai kahi mea koʻikoʻi. ʻO ka pono wai maʻamau, a me ka hoʻopuka ʻana i ka mortar pili, pili i ka hana ʻana o ka mortar gypsum, ʻo ia hoʻi ka nui o ka limestone, perlite, etc. Hiki i ka hoʻohui ʻana o ka methyl cellulose ether ke hoʻoponopono pono i ka koi wai a me ka hoʻopuka ʻana o ka mortar gypsum mortar.
(3) Paʻa wai
ʻO ka paʻa wai o ka methyl cellulose ether, hiki i kekahi ke hoʻololi i ka manawa wehe a me ke kaʻina coagulation o ka ʻōnaehana gypsum mortar, i mea e hoʻoponopono ai i ka manawa hana o ka ʻōnaehana; hiki i ka methyl cellulose ether ke hoʻokuʻu mālie i ka wai no ka manawa lōʻihi.
(4) Hoʻoponopono i ka rheology
Hiki i ka hoʻohui ʻana o ka methyl cellulose ether ke hoʻoponopono pono i ka rheology o ka ʻōnaehana plastering gypsum, no laila e hoʻomaikaʻi ai i ka hana hana: ʻoi aku ka maikaʻi o ka hana ʻana o ka gypsum mortar, ʻoi aku ka maikaʻi o ka anti-sag performance, ʻaʻohe adhesion me nā mea hana a me ka hana pulping kiʻekiʻe, etc.
Pehea e koho ai i ka methyl cellulose ether kūpono?
Pane: Loaʻa i nā huahana methyl cellulose ether nā ʻano like ʻole e like me kā lākou ʻano etherification, degere o ka etherification, viscosity o ka hoʻonā wai, nā waiwai kino e like me ka fineness particle, nā ʻano solubility a me nā ʻano hoʻololi. No ka loaʻa ʻana o ka hopena hoʻohana maikaʻi loa, pono e koho i ka brand cellulose ether kūpono no nā kahua noi like ʻole, a ʻo ka brand i koho ʻia o ka methyl cellulose ether pono e kūpono me ka ʻōnaehana mortar i hoʻohana ʻia.
Loaʻa nā methyl cellulose ethers i nā viscosities like ʻole e kūpono i nā pono like ʻole. Hiki i ka methyl cellulose ether ke pāʻani wale i ka hana ma hope o ka hoʻoheheʻe ʻia ʻana, a pono e hoʻololi ʻia kona helu dissolution i ke kahua noi a me ke kaʻina hana. Ua kūpono ka huahana pauda maikaʻi no nā ʻōnaehana momi maloʻo hui pū ʻia (e like me ka plaster plastering plaster). Hiki i nā ʻāpana maikaʻi loa o ka methyl cellulose ether ke hōʻoia i ka hemo wikiwiki ʻana, i hiki ke hoʻokō pono ʻia kāna hana maikaʻi i ka manawa pōkole ma hope o ka hoʻokumu ʻia ʻana o ka mortar pulu. Hoʻonui ia i ka paʻa a me ka paʻa ʻana o ka wai o ka mortar i ka manawa pōkole loa. He kūpono loa kēia hiʻohiʻona no ka hana mechanical, no ka mea ma keʻano laulā, pōkole loa ka manawa hui ʻana o ka wai a me ka maloʻo maloʻo i ka wā hana mechanical.
He aha ka paʻa wai o ka methyl cellulose ether?
Pane: ʻO ka hana koʻikoʻi o nā māka like ʻole o ka methyl cellulose ether (MC) ʻo ko lākou hiki ke paʻa wai i nā ʻōnaehana mea kūkulu. I mea e loaʻa ai ka maikaʻi o ka hana, pono e mālama i ka wai i loko o ka mortar no ka manawa lōʻihi. No ka hana ʻana o ka wai ma ke ʻano he lubricant a me ka mea hoʻoheheʻe ma waena o nā ʻāpana inorganic, hiki ke kāleka ʻia nā morta ʻāpana lahilahi a hiki ke hoʻopaʻa ʻia i nā morta i hoʻopaʻa ʻia me nā trowels. ʻAʻole pono e hoʻomaʻemaʻe mua ʻia nā paia absorbent a i ʻole nā tile ma hope o ka hoʻohana ʻana i ka cellulose ether-added mortar. No laila hiki iā MC ke lawe i nā hopena kūkulu wikiwiki a me ka waiwai.
No ka hoʻonohonoho ʻana, pono e hoʻomaʻemaʻe ʻia nā mea cementitious e like me ka gypsum me ka wai. Hiki i ka nui kūpono o ka MC ke mālama i ka wai i loko o ka mortar no ka manawa lōʻihi, i hiki ke hoʻomau i ka hoʻonohonoho a me ka paʻakikī. ʻO ka nui o ka MC i koi ʻia no ka loaʻa ʻana o ka mana paʻa wai kūpono e pili ana i ka absorptivity o ke kumu, ka haku ʻana o ka mortar, ka mānoanoa o ka papa mortar, ke koi wai o ka mortar, a me ka manawa hoʻonohonoho o ka mea sima.
ʻOi aku ka maikaʻi o ka nui o ka MC, ʻoi aku ka wikiwiki o ka mānoanoa o ka mortar.
