Pehea e koho ai i ka hydroxypropyl methylcellulose mai ka paʻa wai

ʻO ka paʻa wai mai ka hydroxypropyl methylcellulose kekahi o nā waiwai nui o ka hydroxypropyl methylcellulose. ʻO nā mea e like me ke ea wela, ka mahana a me ka wikiwiki o ka makani e hoʻopili i ka nui o ka volatilization o ka wai i loko o ka mortar sima a me nā huahana gypsum. No laila, i nā kau like ʻole, aia kekahi mau ʻokoʻa i ka hopena paʻa wai o nā huahana me ka nui o ka hydroxypropyl methylcellulose i hoʻohui ʻia.

ʻO ka maʻamau, ʻoi aku ka kiʻekiʻe o ka viscosity o ka hydroxypropyl methylcellulose, ʻoi aku ka maikaʻi o ka hopena o ka mālama ʻana i ka wai, akā e hoʻemi ʻia ka hopena o ka viscosity i ka paʻa ʻana o ka wai ke ʻoi aku ka viscosity ma mua o 100,000 mpa.s. No ka hydroxypropyl methylcellulose me ka viscosity oi aku ma mua o 100,000, pono e hoʻonui i ka nui o ka hydroxypropyl methylcellulose e hoʻonui nui i ka pae paʻa wai.

I ke kūkulu kikoʻī, hiki ke hoʻoponopono ʻia ka hopena paʻa wai o ka slurry ma ka hoʻonui a hoʻemi ʻana i ka nui o ka hydroxypropyl methylcellulose. Hiki i nā huahana Hydroxypropyl methylcellulose series ke hoʻoponopono pono i ka pilikia o ka paʻa ʻana o ka wai ma lalo o ke kiʻekiʻe kiʻekiʻe. I nā kau wela kiʻekiʻe, ʻoi aku hoʻi ma nā wahi wela a maloʻo a me ka hana ʻana i ka ʻāpana lahilahi ma ka ʻaoʻao o ka lā, koi ʻia ka hydroxypropyl methylcellulose kiʻekiʻe e hoʻomaikaʻi i ka paʻa ʻana o ka wai o ka slurry.

ʻO ka hydroxypropyl methylcellulose kūlana kiʻekiʻe he kūlike maikaʻi loa. Hoʻokaʻawale ʻia kāna mau pūʻulu methoxyl a me hydroxypropoxyl ma ke kaulahao mole cellulose. Hiki iā ia ke hoʻomaikaʻi i nā ʻātoma oxygen ma nā paʻa hydroxyl a me ether. ʻO ka hiki i ka hui wai ke hana i nā paʻa hydrogen e hoʻohuli i ka wai manuahi i wai i hoʻopaʻa ʻia, a laila e hoʻomalu pono i ka hoʻoheheʻe ʻana o ka wai ma muli o ke anuanu kiʻekiʻe a loaʻa ka paʻa wai kiʻekiʻe.

High-quality hydroxypropyl methylcellulose hiki like a me ka hoʻopuehu maikaʻi i loko o ka mortar sima a me nā huahana gypsum-based, ʻōwili i nā mea paʻa paʻa a pau, a hana i kahi kiʻi ʻoniʻoni, a e hoʻokuʻu mālie ʻia ka wai ma ke kumu no ka manawa lōʻihi. Loaʻa ka hopena hydration me ka mea gelling inorganic, a laila e hōʻoia i ka ikaika paʻa a me ka ikaika compressive o ka mea. No laila, i ke kūkulu ʻana i ke kauwela kiʻekiʻe, i mea e hoʻokō ai i ka hopena paʻa wai, pono ia e hoʻohui i nā huahana hydroxypropyl methylcellulose kiʻekiʻe i ka nui e like me ke ʻano, inā ʻaʻole, lawa ʻole ka hydration, hoʻemi ʻia ka ikaika, a hiki mai ka haki. i ka maloʻo nui. ʻO nā pilikia maikaʻi e like me ka hollowing, hollowing a me ka hāʻule ʻana e hoʻonui i ka paʻakikī o ke kūkulu ʻana no nā limahana. Ke hāʻule nei ka mahana, hiki ke hoʻemi iki ʻia ka nui o ka hydroxypropyl methylcellulose i hoʻohui ʻia, a hiki ke hoʻokō ʻia ka hopena paʻa wai like.
