Ka hopena o ka Cellulose Ether i ka ikaika o ka mortar

ʻO nā cellulose ethers nā mea hoʻohui multifunctional i nā mea kūkulu hale, me nā morta, a ua hoʻohana ʻia i ka ʻoihana kūkulu hou no nā makahiki he mau makahiki. Loaʻa ia ma nā ʻano a me nā māka, a ʻo ke koho ʻana o ka cellulose ether e pili ana i ka noi i manaʻo ʻia a me nā waiwai o ka huahana hope.

Ma keʻano laulā, hoʻomaikaʻi ka cellulose ether i ka hana o ka mortar ma o ka hoʻonui ʻana i kāna hana hana, paʻa wai a hoʻopili i ka substrate. Ma kēiaʻatikala, e nānā mākou i ka hopena o ka cellulose ethers ma ka mortar adhesion, kahi waiwai nui o nā mortar.

ʻO ka Adhesion ka hiki ke hoʻopili i kekahi mea e like me kahi substrate kahi e hoʻopili ʻia ai ka mortar. He mea koʻikoʻi ka hoʻopili ʻana i ka mortar i ka lōʻihi a me ka hana lōʻihi o nā hale kūkulu hale. ʻO nā mea e pili ana i ka pili ʻana o ka mortar e pili ana i nā waiwai substrate, nā waiwai mortar, a me nā kūlana kaiapuni.

Hoʻomaikaʻi ʻo Cellulose ether i ka hoʻopili ʻana o ka mortar ma o ka hoʻomaikaʻi ʻana i nā waiwai rheological a me nā mechanical o ka mortar. ʻO ka mea mua, hoʻomaikaʻi nā cellulose ethers i ka rheology o nā mortar ma o ka hoʻonui ʻana i kā lākou hana a hoʻemi i ka hoʻokaʻawale. ʻO ka maʻalahi o ka hui ʻana, waiho ʻia a hoʻopau ʻia, ʻoiai ʻo ka hoʻokaʻawale ʻana e pili ana i ka hoʻokaʻawale ʻana o nā ʻāpana mortar i ka wā e hui ai a lawelawe ʻia paha. Hoʻomaikaʻi ʻia ka rheology o ka mortar, hiki iā ia ke kahe a hoʻopiha i nā āpau ma waena o ka substrate a me ka mortar no ka hoʻopili maikaʻi ʻana.

ʻO ka lua, hoʻomaikaʻi nā cellulose ethers i nā waiwai mechanical o ka mortar, e like me kona tensile a me ka ikaika compressive, he mea koʻikoʻi ia no ka hoʻopili ʻana o ka mortar i ka substrate. Hoʻomaikaʻi ʻo Cellulose ether i nā waiwai mechanical o ka mortar ma o ka hoʻomaikaʻi ʻana i kona hydration, ke kaʻina hana e hana ai ka cement i ka mortar me ka wai e hana i kahi hale paʻakikī.

ʻO ka loaʻa ʻana o ka cellulose ether i loko o ka mortar e hoʻolōʻihi i ka wikiwiki o ka hoʻoheheʻe ʻana o ka wai i loko o ka mortar, e hopena i kahi kaʻina hydration lōʻihi. ʻO ke kaʻina hana hydration lōʻihi e hana i kahi paʻa ākea a ikaika ma waena o ka mortar a me ka substrate no ka hoʻopili maikaʻi ʻana.

ʻO nā eter cellulose i hoʻohana ʻia i loko o nā morta e hele mai i nā ʻano like ʻole a me nā ʻano, me ka methylcellulose, hydroxyethylcellulose, a me ka hydroxypropylcellulose. ʻO Methylcellulose ke ʻano maʻamau a kūpono ia no nā ʻano noi like ʻole ma muli o kona kiʻekiʻe kiʻekiʻe o ka paʻa ʻana o ka wai, hiki ke hana, a me ka hoʻopili maikaʻi ʻana. ʻO ka Hydroxyethyl cellulose, ma ka ʻaoʻao ʻē aʻe, he hydrophilic a hiki ke hoʻopaʻa a mālama i ka wai, a laila e hoʻonui ai i ka hana o ka mortar a me kona pili ʻana i ka substrate. He kūpono ʻo Hydroxypropyl cellulose no ka mānoanoa a me ka hoʻonui ʻana i nā waiwai rheological o nā morta, pēlā e hoʻomaikaʻi ai i ka adhesion.

I ka hōʻuluʻulu ʻana, he mea hoʻohui waiwai ka cellulose ether i ka ʻoihana kūkulu hale a he hana koʻikoʻi i ka hoʻomaikaʻi ʻana i ka pili ʻana o ka mortar. ʻO ka loaʻa ʻana o ka cellulose ether i loko o ka mortar e hoʻomaikaʻi i kāna mau rheological a me nā ʻano mechanical, e hopena i ka hana ʻoi aku ka maikaʻi, ka hydration a me ka hoʻopili ʻana i ka substrate. ʻO ke koho o ka cellulose ether e pili ana i ka noi i manaʻo ʻia a me nā waiwai i makemake ʻia o ka huahana hope. Ke hoʻohana nei i ka cellulose ether i loko o ka mortar, pono e hahai ʻia nā ʻōlelo a ka mea hana e hoʻokō i nā hopena maikaʻi loa a hōʻoia i ka paʻa a me ka hana lōʻihi o ka hale kūkulu hale.
