ʻO HPMC Hydroxypropyl methyl cellulose, ka mea i ʻike ʻia he hydroxypropyl methyl cellulose ether (HPMC), cellulose hydroxypropyl methyl ether, ʻo ia ke koho ʻana o ka pulupulu maʻemaʻe maʻemaʻe ma ke ʻano he mea maka, ma lalo o nā kūlana alkaline e ka etherification kūikawā a me ka hoʻomākaukau.
Hydroxypropyl methyl cellulose HPMC i hoʻohana 'ia i loko o ke kūkulu 'ana, cellulose etera i hoʻohui 'ia ka nui he haʻahaʻa loa, akā hiki ke hoʻomaikaʻi maikaʻi i ka hana o ka pulu pulu, ʻo ka hana ʻana o ka mortar he mea hoʻohui nui. I kēia manawa, ʻo ka hydroxypropyl methyl cellulose i hoʻohana ʻia i ka mortar cellulose ether ka nui o ka hydroxypropyl methyl cellulose ether (HPMC). ʻO ka Hydroxypropyl methyl cellulose i ke kūkulu ʻana i ka mortar maloʻo HPMC ka mea nui i ka mālama ʻana i ka wai, ka mānoanoa, ka hoʻomaikaʻi ʻana i ka hana hana.
1, kūkulu ʻia ʻana i ka hamo hamo hamo
Hiki i ka paʻa ʻana o ka wai kiʻekiʻe ke hoʻomaʻemaʻe piha i ka sima, hoʻonui nui i ka ikaika paʻa, a hiki ke hoʻomaikaʻi kūpono i ka ikaika tensile a me ka ikaika shear, hoʻomaikaʻi nui i ka hopena kūkulu, hoʻomaikaʻi i ka hana pono.
2, ka wai pale putty
I loko o ka putty HPMC hydroxypropyl methyl cellulose ether ka mea nui i ke kuleana o ka paʻa ʻana o ka wai, ka hoʻopaʻa ʻana a me ka lubrication, e pale i ke ʻano o nā māwae a me ka dehydration i hoʻokumu ʻia e ka wikiwiki o ka wai, a hoʻonui i ka adhesion o ka putty, hoʻemi i ke ʻano o ke kahe e kau ana i loko. ke kukulu ana, i maalahi ke kukulu ana.
3, pena gypsum moʻo
I ka gypsum series o nā huahana HPMC hydroxypropyl methyl cellulose ether e pāʻani nui i ka paʻa wai, hoʻonui i ka lubrication a me nā hopena ʻē aʻe, i ka manawa like he hopena lohi, e hoʻoponopono i ke kaʻina hana hana pahu, ʻaʻole hiki i ka ikaika mua ke pilikia, hiki ke hoʻolōʻihi. ka manawa hana.
4, mea hoʻohana pili
Hoʻohana nui ʻia e like me ka mānoanoa, hiki ke hoʻomaikaʻi i ka ikaika tensile a me ka ikaika shear, hoʻomaikaʻi i ka uhi ʻana, hoʻonui i ka adhesion a me ka ikaika paʻa.
5, ka mīkini hoʻokuʻu waho
HPMC Hydroxypropyl methyl cellulose, cellulose ether i loko o ka mea e pili ana i ka hoʻopaʻa ʻana, hoʻonui i ka ikaika, e maʻalahi no ka uhi ʻana i ka mortar, hoʻomaikaʻi i ka hana pono, i ka manawa like ʻoi aku ke kūpaʻa kū i ke kahe, hiki ke hoʻolōʻihi i ka manawa hana o ka mortar. hoʻomaikaʻi i ka shrinkage a me ka thermal fatigue resistance, hoʻomaikaʻi i ka maikaʻi o ka ʻili, hoʻomaikaʻi i ka ikaika paʻa.
6, mea hoʻopaʻa tile seramika
ʻAʻole hiki ke hoʻopaʻa ʻia ka wai kiʻekiʻe ma mua o ka hoʻomaʻemaʻe ʻana a i ʻole ka pulu ceramic tile a me ke kumu, hoʻomaikaʻi nui i kona ikaika paʻa, hiki i ka slurry ke lōʻihi ke kūkulu ʻana i ka pōʻai, palupalu, ʻaʻahu, kūpono ke kūkulu ʻana, a maikaʻi ke kūʻē ʻana i ka makū.
7, seam filling agent, jointing agent
ʻO ka hoʻohui o ka hydroxypropyl methyl cellulose HPMC cellulose ether e loaʻa iā ia ka adhesion lihi maikaʻi, ka haʻahaʻa haʻahaʻa a me ke kūpaʻa lole kiʻekiʻe, pale i ka mea kumu mai ka pōʻino mechanical, e pale i ka hopena o ka infiltration i ka hale holoʻokoʻa.
8, mea hoʻonanea ponoʻī
ʻO Hydroxypropyl methyl cellulose cellulose ether paʻa paʻa e hōʻoia i ka wai maikaʻi a me ka hiki ke hoʻopaʻa pono iā ia iho, e kāohi i ka nui o ka paʻa ʻana o ka wai i hiki iā ia ke hoʻopaʻa koke, hoʻemi i ka haki ʻana a me ka contraction.
9. Pena Latex
Hydroxypropyl methyl cellulose i loko o ka ʻoihana uhi cellulose ether e like me ke kiʻiʻoniʻoni-mua, thickening agent, emulsifier a me ka stabilizer i hoʻohana ʻia, e hana maikaʻi i ka abrasion kūʻē, ka uhi ʻana, adhesive, hoʻomaikaʻi i ka qualitative o ka waiwai PH o ka ʻili o ka ʻili, a me ka hopena o ka hui ʻana o ka ʻili. ʻoi aku ka maikaʻi, hana ʻo Gao Baoshui i ka maikaʻi o ka brushing a me ka waiwai kahe.
10. ʻO nā seramika honeycomb
I ka honeycomb ceramics hou, hāʻawi ʻia ka billet i ka lubricity, ka paʻa wai a me ka hoʻonui ʻana i ka ikaika.
Hiki i nā huahana hydroxypropyl methyl cellulose series maikaʻi ke hoʻoponopono i ka pilikia o ka paʻa ʻana o ka wai ma lalo o ka wela kiʻekiʻe. I ke kau wela kiʻekiʻe, ʻoi aku hoʻi ma nā wahi wela a maloʻo a me ke kūkulu ʻia ʻana o ka papa lahilahi ma ka ʻaoʻao o ka lā, pono ka HPMC kiʻekiʻe e hoʻomaikaʻi i ka paʻa ʻana o ka wai o ka slurry. ʻO ka HPMC kūlana kiʻekiʻe, maikaʻi loa ke kūlike, ʻo kāna mau methoxy a me hydroxypropyl pūʻulu ma ka cellulose molecular chain uniform distribution, hiki ke hoʻomaikaʻi i ka hydroxyl a me ka ether bond ma nā ʻātoma oxygen a me ka hui wai hydrogen hiki ke hoʻopaʻa ʻia, e hana i ka wai manuahi i ka wai hui, i mea e pono ai. e hoʻomalu i ka hoʻoheheʻe ʻana o ka wai ma muli o ke ʻano wela wela, e hoʻokō i ka paʻa wai kiʻekiʻe.
High quality o hydroxypropyl methyl cellulose hiki uniformly a me ka hoʻopuehu maikaʻi i loko o ka sima a me ka plaster huahana, a puʻupuʻu i nā mea paʻa paʻa a pau, a hana i ka papa o ka wetting kiʻiʻoniʻoni, ka makū i loko o ke kumu no ka manawa lōʻihi hoʻokuʻu mālie, a inorganic cementitious mea hydration hopena. , i mea e hōʻoia ai i ka ikaika pili a me ka ikaika compressive o nā mea. No laila, i ke kauwela kauwela kūkulu ʻia, i mea e hoʻokō ai i ka hopena o ka mālama ʻana i ka wai, e like me ke ʻano e hoʻohui i nā huahana HPMC kiʻekiʻe, inā ʻaʻole, e maloʻo wikiwiki ʻia ma muli o ka lawa ʻole o ka hydration, ka emi ʻana o ka ikaika, ka haki ʻana, ka pahu pahu a me hāʻule a me nā pilikia maikaʻi ʻē aʻe, akā hoʻonui pū i ka paʻakikī o ka hana ʻana o nā limahana. I ka emi ʻana o ka mahana, hiki ke hoʻemi ʻia ka nui o ka HPMC, a hiki ke loaʻa ka hopena paʻa wai like.
