Ka mālama ʻana i ka wai maiʻO ka Hydroxypropyl Methyl Celluloseʻo ia kekahi o nā waiwai koʻikoʻi o Hydroxypropyl Methyl Cellulose. ʻO nā mea e like me ka mahana o ka ea, ka mahana a me ka wikiwiki o ke kaomi makani e hoʻopilikia i ka nui o ka volatilization o ka wai i loko o ka sima 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 like o Hydroxypropyl Methyl Cellulose i hoʻohui ʻia.
Ma keʻano laulā, ʻo ke kiʻekiʻe o ka viscosity o Hydroxypropyl Methyl Cellulose, ʻoi aku ka maikaʻi o ka hopena paʻa wai, akā e emi ana ka hopena o ka viscosity ma ka paʻa wai ke ʻoi aku ka viscosity ma mua o 100,000 mpa.s. No ka Hydroxypropyl Methyl Cellulose me ka viscosity ma mua o 100,000, pono e hoʻonui i ka nui o Hydroxypropyl Methyl Cellulose e hoʻonui nui i ka nui o ka paʻa wai.
I ke kūkulu ʻana kikoʻī, hiki ke hoʻoponopono ʻia ka hopena paʻa wai o ka slurry ma ka hoʻonui ʻana a i ʻole ka hoʻemi ʻana i ka nui o Hydroxypropyl Methyl Cellulose. Hiki i nā huahana moʻo Hydroxypropyl Methyl Cellulose ke hoʻoponopono pono i ka pilikia o ka paʻa wai ma lalo o ke ana wela kiʻekiʻe. I nā kau wela kiʻekiʻe, ʻoi aku hoʻi i nā wahi wela a maloʻo a me ke kūkulu ʻana i ka papa lahilahi ma ka ʻaoʻao lā, pono ka hydroxypropyl methylcellulose kiʻekiʻe e hoʻomaikaʻi i ka paʻa wai o ka slurry.
He ʻano like maikaʻi loa ka Hydroxypropyl Methyl Cellulose kiʻekiʻe. Ua hoʻolaha like ʻia kona mau hui Methoxy a me Hydroxypropoxy ma ke kaulahao molekala cellulose. Hiki iā ia ke hoʻomaikaʻi i nā ʻātoma oxygen ma nā pilina hydroxyl a me ether. ʻO ka hiki ke hui pū ʻia ka wai e hana i nā pilina hydrogen e hoʻohuli i ka wai manuahi i wai paʻa, no laila e kāohi pono ana i ka mahu wai i hoʻokumu ʻia e ke aniau wela kiʻekiʻe a hoʻokō i ka paʻa wai kiʻekiʻe.
Kūlana kiʻekiʻehydroxypropyl Methyl Cellulosehiki ke hoʻopuehu like a maikaʻi i loko o ka sima sima a me nā huahana gypsum-based, e kāʻei i nā ʻāpana paʻa a pau, a hana i kahi ʻili pulu, a e hoʻokuʻu mālie ʻia ka makū i loko o ke kumu i kahi manawa lōʻihi. Hana ʻia kahi hopena hydration me ka mea gelling inorganic, no laila e hōʻoiaʻiʻo ana i ka ikaika o ka hoʻopaʻa a me ka ikaika compressive o ka mea. No laila, i ke kūkulu ʻana i ke kauwela wela kiʻekiʻe, i mea e hoʻokō ai i ka hopena paʻa wai, pono e hoʻohui i nā huahana Hydroxypropyl Methyl Cellulose kiʻekiʻe i nā nui lawa e like me ke ʻano, inā ʻaʻole, ʻaʻole lawa ka hydration, ka ikaika i hoʻemi ʻia, a me ka haki ʻana ma muli o ka maloʻo nui. ʻO nā pilikia maikaʻi e like me ka hollowing, hollowing a me ka hāʻule ʻana e hoʻonui pū i ka paʻakikī o ke kūkulu ʻana no nā limahana. I ka hāʻule ʻana o ka mahana, hiki ke hoʻemi mālie ʻia ka nui o Hydroxypropyl Methyl Cellulose i hoʻohui ʻia, a hiki ke hoʻokō ʻia ka hopena paʻa wai like.
