Hoʻopau i ka HPMC

I loko o ka ʻoihana kūkulu, hoʻokomo pinepine ʻia ka HPMC i ka wai kū ʻole, a hoʻoheheʻe ʻia ka huahana HPMC wale nō e hoʻoponopono i ka helu hoʻoheheʻe.

Ma hope o ka waiho ʻia ʻana i loko o ka wai kū ʻole wale nō, ʻo ka huahana e puʻupuʻu koke me ka ʻole o ka hoʻopuehu ʻana he huahana me ka mālama ʻole ʻia o ka ʻili;ma hope o ka waiho ʻia ʻana i loko o ka wai kūʻokoʻa wale nō, ʻo ka huahana hiki ke hoʻopuehu a ʻaʻole hui pū kekahi huahana me ka mālama ʻana i ka ʻili.

Ke hoʻoheheʻe ʻia ka huahana HPMC i mālama ʻole ʻia, hoʻoheheʻe ʻia kona ʻāpana hoʻokahi a hana wikiwiki i kahi kiʻiʻoniʻoni, ʻaʻole hiki i ka wai ke komo i nā ʻāpana ʻē aʻe, e hopena i ka hoʻohui a me ka hoʻohui.Kapa ʻia ʻo ia ka huahana koke ma ka mākeke i kēia manawa.ʻO nā hiʻohiʻona o ka HPMC ʻaʻole i hoʻoponopono ʻia ʻo ia: hiki ke hoʻoheheʻe ʻia nā ʻāpana pākahi i nā kūlana kūʻokoʻa, alkaline, a me ka ʻakika, akā ʻaʻole hiki ke hoʻopuehu ma waena o nā ʻāpana i loko o ka wai, e hopena i ka agglomeration a me ka hui ʻana.Ma ka hana maoli, ma hope o ka hoʻopuehu kino ʻana o kēia pūʻulu o nā huahana a me nā ʻāpana paʻa e like me ka pauka rubber, cement, one, etc., wikiwiki loa ka dissolution rate, ʻaʻohe agglomeration a i ʻole agglomeration.I ka wā e pono ai e hoʻoheheʻe i nā huahana HPMC ma kahi kaʻawale, pono e hoʻohana ʻia kēia pūʻulu o nā huahana me ka akahele, no ka mea, e agglomerate a lilo i mau puʻupuʻu.Inā pono e hoʻopau kaʻawale i ka huahana HPMC ʻole, pono e hoʻopuehu like ʻia me ka wai wela 95 ° C, a laila hoʻomaloʻo e hoʻoheheʻe.

ʻO nā ʻāpana huahana HPMC i mālama ʻia i ka ʻili, i ka wai kūʻokoʻa, hiki ke hoʻopuehu ʻia nā ʻāpana pākahi me ka ʻole o ka agglomeration, akā ʻaʻole e hoʻopuka koke i ka viscosity.Ma hope o ka hoʻoulu ʻana no kekahi manawa, ua luku ʻia ke ʻano kemika o ka mālama ʻana i ka ʻili, a hiki i ka wai ke hoʻoheheʻe i nā ʻāpana HPMC.I kēia manawa, ua hoʻopuehu piha ʻia nā ʻāpana huahana a ua lawa ka wai, no laila ʻaʻole e hōʻuluʻulu a agglomerate ka huahana ma hope o ka hemo ʻana.ʻO ka wikiwiki o ka hoʻopuehu ʻana a me ka wikiwiki o ka hemo ʻana ma muli o ke ʻano o ka mālama ʻana i ka ʻili.Inā liʻiliʻi ka hoʻomaʻamaʻa ʻana i ka ʻili, lohi ka wikiwiki o ka hoʻopuehu ʻana a me ka wikiwiki pipili;ʻoiai ʻo ka huahana me ka mālama ʻili hohonu he wikiwiki ka hoʻopuehu ʻana a me ka wikiwiki pipili.Inā makemake ʻoe e hoʻoheheʻe koke i kēia pūʻulu o nā huahana i kēia mokuʻāina, hiki iā ʻoe ke hāʻule i kahi liʻiliʻi o nā mea alkaline ke hoʻoheheʻe ʻia lākou.ʻO ka mākeke o kēia manawa ka mea maʻamau i kapa ʻia he huahana hoʻoheheʻe lohi.ʻO nā hiʻohiʻona o nā huahana HPMC i mālama ʻia i ka ʻili: i loko o ka wai wai, hiki i nā ʻāpana ke hoʻopuehu me kekahi, hiki ke hoʻoheheʻe koke i ke kūlana alkaline, a hoʻoheheʻe mālie i ke kūlana kūʻokoʻa a me ka acidic.

Ma ka hana hana maoli, hoʻoheheʻe pinepine ʻia kēia pūʻulu o nā huahana ma hope o ka hoʻopuehu ʻia ʻana me nā mea ʻāpana paʻa ʻē aʻe ma lalo o nā kūlana alkaline, a ʻaʻole ʻokoʻa kona helu dissolution me nā huahana i mālama ʻole ʻia.He kūpono no ka hoʻohana ʻana i nā huahana i hoʻoheheʻe wale ʻia, me ka ʻole o ka caking a i ʻole lumps.Hiki ke koho ʻia ke kumu hoʻohālike kikoʻī o ka huahana e like me ka helu dissolution i koi ʻia e ke kūkulu ʻana.

I loko o ke kaʻina hana, ʻo ia ka mortar sima a i ʻole ka gypsum-based slurry, ʻo ka hapa nui o lākou he ʻōnaehana alkaline, a ʻo ka nui o ka HPMC i hoʻohui ʻia he liʻiliʻi loa, hiki ke hoʻopuehu like ʻia i waena o kēia mau ʻāpana.Ke hoʻohui ʻia ka wai, e hemo koke ka HPMC.ʻO ka hydroxypropyl methylcellulose maoli wale nō hiki ke kū i ka hoʻāʻo o nā kau ʻehā: ke kaʻina hana e hoʻomalu pono ʻia e hana i ka HPMC, a ua paʻa kona pani ʻana a ua maikaʻi loa ke ʻano like.He akaka a ʻākala kona ʻano wai, me ka liʻiliʻi o nā fiber manuahi.ʻO ka hoʻohālikelike ʻana me ka pauka rubber, ka sima, ka lime a me nā mea nui ʻē aʻe he ikaika loa, hiki ke hana i nā mea nui i ka hana maikaʻi loa.Eia nō naʻe, ʻo HPMC me ka hopena maikaʻi ʻole he nui nā fibers manuahi, ka puʻunaue like ʻole o nā mea pani, paʻa wai maikaʻi ʻole a me nā waiwai ʻē aʻe, ka hopena i ka nui o ka wai i ka wā wela.Eia naʻe, ʻo ka HPMC i kapa ʻia me ka nui o nā mea hoʻohui he paʻakikī ke hoʻonohonoho pū kekahi me kekahi, no laila ʻoi aku ka maikaʻi o ka hana o ka mālama ʻana i ka wai.Ke hoʻohana ʻia ka HPMC maikaʻi ʻole, e hoʻoulu ʻia nā pilikia e like me ka ikaika slurry haʻahaʻa, ka manawa wehe pōkole, ka pauka, ka māhā, ka hollowing a me ka hoʻokahe ʻana, e hoʻonui ai i ka paʻakikī o ke kūkulu ʻana a hoʻemi nui i ka maikaʻi o ka hale.ʻO ia ka cellulose ether, hiki ke loaʻa nā hopena like ʻole.
