ʻO ka Hydroxypropyl methylcellulose ether (HPMC) ka paʻa ʻana o ka wai a me nā hopena mānoanoa i ka pahu sima a me ka gypsum-based mortar, a hiki ke hoʻomaikaʻi maikaʻi i ka hoʻopili ʻana a me ke kūpaʻa kūpaʻa o ka mortar.
ʻO nā mea e like me ke kinoea wela, ka wela, a me ka piʻi ʻana o ke kinoea e hōʻino i ka wikiwiki o ka hoʻoheheʻe ʻana o ka wai i loko o nā morta sima a me nā huahana gypsum.No laila, ʻokoʻa ka huina like o ka hydroxypropyl methylcellulose ether (HPMC) pāʻoihana no ka mālama ʻana i ka loaʻa o ka wai i kēlā me kēia kau.
I ka ninini ʻana i ka koneki, hiki ke hoʻoponopono ʻia ka hopena o ka laka wai e like me ka hoʻonui a i ʻole ka emi ʻana o ke kahe kahe kiʻekiʻe.ʻO ka laka paʻa wai o ka hydroxypropyl methylcellulose ether i ka wela kiʻekiʻe kahi waiwai hōʻailona nui e ʻike ai i ka maikaʻi o ka hydroxypropyl methylcellulose ether.
Hiki i nā huahana hydroxypropyl methylcellulose ether (HPMC) kiʻekiʻe ke mālama i ka pilikia o ka laka wai wela.I nā kau wela kiʻekiʻe, ʻoi aku ka nui o nā wahi wela a me nā wahi haʻahaʻa a me nā hale ʻenekinia chromatography, pono e hoʻohana i ka hydroxypropyl methylcellulose ether (HPMC) kiʻekiʻe e hoʻomaikaʻi i ka hoʻoheheʻe wai o ka slurry.
ʻO ka māhele o ka hydroxypropyl methylcellulose ether (HPMC) kiʻekiʻe loa he ʻano like ʻole, a ua māhele like ʻia kāna mau methoxy a me nā hui hydroxypropyl ma ke kaulahao molecular structure o ka methyl cellulose, hiki ke hoʻonui i ka hanauna o nā moleke oxygen ma nā paʻa hydroxyl a me ether.ʻO ka hiki ke hana i nā mea paʻa covalent.
Hiki iā ia ke hoʻomalu pono i ka evaporation o ka wai i hoʻokumu ʻia e ka wā wela a hoʻokō i ka hopena maoli o ka laka wai kiʻekiʻe.Loaʻa ʻia ka Hydroxypropyl Methylcellulose Ether (HPMC) kiʻekiʻe ma nā morta hui ʻia a me ka plaster o nā mea hana Paris.
Hoʻopili ʻia nā ʻāpana paʻa a pau e hana i kahi kiʻiʻoniʻoni pulu.Hoʻokuʻu mālie ʻia ka wai maʻamau no ka manawa lōʻihi a loaʻa i kahi hopena coagulation me nā mea inorganic a me nā mea collagen e hōʻoia i ka ikaika compressive paʻa a me ka ikaika tensile.
No laila, ma nā kahua kūkulu wela kiʻekiʻe i ke kauwela, i mea e hoʻokō ai i ka hopena maoli o ka mālama ʻana i ka wai, pono nā kānaka e hoʻohui i nā huahana hydroxypropyl methylcellulose ether (HPMC) kiʻekiʻe e like me ka mea huna huna, inā ʻaʻole lākou e pōkole ka wai ma muli o nele wai.ʻO nā pilikia o ka maikaʻi o ka huahana e like me ka paʻa, hoʻemi ʻia ka ikaika compressive, nā māwae, nā ea bulges, a pēlā aku e hoʻomaloʻo nui ai.
Hoʻonui kēia i ka paʻakikī o ke kūkulu ʻana i nā limahana.I ka emi ʻana o ka mahana, hoʻemi mālie ka nui o ka hydroxypropyl methylcellulose ether (HPMC) no ka loaʻa ʻana o ka makū like.
