Focus on Cellulose ethers

E ʻokoʻa anei ka paʻa wai o ka hydroxypropyl methylcellulose (HPMC) i nā kau like ʻole?

ʻO ka Hydroxypropyl methyl cellulose ether (HPMC) ka hana o ka paʻa ʻana o ka wai a me ka mānoanoa i ka mortar sima a me ka gypsum-based mortar, a hiki ke hoʻomaikaʻi maikaʻi i ka adhesion a me ke kūpaʻa kūpaʻa o nā mea mortar.

ʻO nā mea e like me ke kinoea wela, ka mahana a me ka piʻi ʻana o ka ea he hopena maikaʻi ʻole i ka wikiwiki o ka hoʻoheheʻe ʻana o ka wai mai ka mortar sima a me nā huahana gypsum. No laila, i kēlā me kēia kau, aia kekahi mau ʻokoʻa i ka hoʻohui ʻana i ka nui like o nā huahana hydroxypropyl methylcellulose ether (HPMC) no ka mālama pono ʻana i ka wai.

I ka ninini ʻana, hiki ke hoʻoponopono ʻia ka hopena paʻa wai ma o ka hoʻonui ʻana a me ka hoʻohaʻahaʻa ʻana i ke kahe ʻāpana. ʻO ka nui o ka mālama ʻana i ka wai o ka hydroxypropyl methyl cellulose ether i ka wela kiʻekiʻe ke kumu helu kuhikuhi e ʻike ai i ka maikaʻi o ka hydroxypropyl methyl cellulose ether.

Hiki i nā huahana hydroxypropyl methylcellulose (HPMC) kiʻekiʻe ke hoʻoponopono i ka pilikia o ka mālama ʻana i ka wai wela. I nā kau wela, ʻoi aku hoʻi ma nā wahi wela a me ka haʻahaʻa a me ka hana chromatography, pono ka hydroxypropyl methylcellulose ether (HPMC) kiʻekiʻe e hoʻomaikaʻi i ka paʻa ʻana o ka wai o ka slurry.

ʻO ka hydroxypropyl methylcellulose ether (HPMC) kiʻekiʻe ka maikaʻi loa, a ua māhele like ʻia kāna methoxyl a me nā hui hydroxypropyl ma ke kaulahao molecular structure o ka methylcellulose, hiki ke hoʻoikaika i ka hana o nā moleke oxygen ma nā paʻa hydroxyl a me ether. ʻO ka hiki ke hana me nā kaula covalent.

Hiki iā ia ke hoʻomalu pono i ka evaporation o ka wai i hoʻokumu ʻia e ka wā wela a hoʻokō i kahi hopena paʻa wai kiʻekiʻe. Hiki ke hoʻohana ʻia ka hydroxypropyl methylcellulose (HPMC) kiʻekiʻe i loko o ka palaki hui ʻia a me ka hana plaster.

E hoʻopili i nā mea paʻa paʻa a pau e hana i kahi kiʻiʻoniʻoni, a e hoʻokuʻu mālie ʻia ka maʻamau o ka hana maʻamau no ka manawa lōʻihi, a e pane me ka mea organik a me ka collagen e hōʻoia i ka ikaika paʻa a me ka ikaika tensile.

No laila, i mea e mālama ai i ka wai ma ke kahua kūkulu i ke kauwela wela, pono mākou e hoʻohui i nā huahana hydroxypropyl methylcellulose (HPMC) kiʻekiʻe e like me ka meaʻai, inā ʻaʻole ia, no ka nele o ka coagulation, hoʻemi ʻia ka ikaika, Cracking, gas drum. a me nā pilikia maikaʻi ʻē aʻe o ka huahana ma muli o ka maloʻo wikiwiki loa.

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) i mea e loaʻa ai ka ʻoluʻolu like.
