Hōʻike huahana:
ʻO ka Hydroxypropyl Methylcellulose (HPMC) he pauka keʻokeʻo ʻona ʻole, ʻaʻohe ʻona. Ma hope o ka hoʻoheheʻe ʻia ʻana i loko o ka wai, e hana ia i kahi hopena viscous akaka. ʻO ia ka non-ionic cellulose ether i hana ʻia mai nā mea polymer kūlohelohe ma o ke ʻano o ka hana kemika. Loaʻa iā ia nā hiʻohiʻona o ka mānoanoa, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gelation, surface activity, hoʻopaʻa ʻana i ka moisture a me ka pale o nā colloids.
Noi:
Hiki ke hoʻoheheʻe ʻia ka wai a me ka mānoanoa: hiki ke hoʻoheheʻe ʻia i ka wai anuanu, a hana i kahi hopena viscous akaka.
Hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik: No ka mea aia kekahi mau pūʻulu hydrophobic methoxy, hiki ke hoʻoheheʻe ʻia kēia huahana i kekahi mau mea hoʻoheheʻe organik.
PH waiwai pa'a: 'O ka viscosity o ka HPMC's aqueous solution ua 'ano pa'a ma ka laulā o ka PH waiwai 3.0-11.0.
Haʻawina ʻili: Loaʻa ka hana ʻili o ka wai HPMC. Loaʻa iā ia ka hopena emulsifying, pale i ka hiki ke colloid a me ka paʻa pili.
Thermal gelation: Ke hoʻomehana ʻia ma luna o kekahi mahana, hiki ke lilo i ka wai o HPMC i opaque, hoʻohua i ka ua, a nalowale ka viscosity. Eia naʻe, ua hoʻololi mālie ʻia i ke kūlana hoʻonā kumu ma hope o ka hoʻoluʻu ʻana.
Haʻahaʻa lehu maʻiʻo: ʻAʻole ionic ka HPMC, hiki ke holoi ʻia me ka wai wela i ka wā o ka hoʻomākaukau ʻana a hoʻomaʻemaʻe maikaʻi ʻia, no laila he haʻahaʻa loa kona ʻano lehu.
Ka pale paʻakai: No ka mea ʻo kēia huahana he non-ionic a non-polymeric electrolyte, ʻano paʻa ia i nā wai wai o nā paʻakai metala a i ʻole nā electrolytes organik.
Ka hopena o ka mālama ʻana i ka wai: No ka mea, he hydrophilic ka HPMC a ʻo kona hoʻoheheʻe wai he ʻeleʻele loa. Hiki ke hoʻohui ʻia i ka mortar, gypsum, pena, a me nā mea ʻē aʻe e mālama i ka paʻa wai kiʻekiʻe i ka huahana.
ʻO ke kūpaʻa ʻana o ka maʻi: He kūpaʻa maikaʻi ʻo ia i ka mildew, a he kūpaʻa viscosity maikaʻi i ka wā mālama lōʻihi.
Lubricity: ʻO ka hoʻohui ʻana i ka HPMC hiki ke hōʻemi i ke koena friction a hoʻomaikaʻi i ka lubricity o nā huahana ceramic extruded a me nā huahana sima.
Ka waiwai hana kiʻiʻoniʻoni: Hiki iā ia ke hana i nā flakes ikaika, maʻalahi, ʻike ʻia me ka ʻaila maikaʻi a me ke kūpaʻa ester.
I nā mea hana, hiki ke hoʻohana ʻia ka cellulose HPMC ma ke ʻano he mea mālama wai a me ka retarder no ka slurry sima e hana ai i ka mortar pumpable.
Ma ke ʻano he mea hoʻopili, hiki i ka hoʻohana ʻana i ka HPMC i nā plasters, gypsum, putty pauka a i ʻole nā mea kūkulu hale ʻē aʻe ke hoʻomaikaʻi i ko lākou pālahalaha a hoʻolōʻihi i ko lākou manawa hana.
Hiki i ka paʻa ʻana o ka wai ke pale i ka paʻi ʻana mai ka haki ʻana ma hope o ka uhi ʻana, a hiki ke hoʻonui i ka ikaika o ka uhi ma hope o ka paʻakikī.
Ma waho aʻe, hiki ke hoʻohana ʻia ke kemika HPMC ma ke ʻano he mea hoʻonui adhesion no ka tile, marble, a me nā mea hoʻonaninani plastik i ka ʻoihana kūkulu.
Eia kekahi, hoʻohana ʻia ka pauka HPMC ma ke ʻano he mānoanoa, stabilizer, emulsifier, excipient, a me ka mea mālama paʻa wai i ka hana ʻana o nā ʻoihana ʻē aʻe, e like me ka petrochemicals, coatings, building materials, paint removers, agricultural chemicals, inks, textile printing and dyeing. nā seramika, ka hana pepa, nā mea hoʻonaninani, etc.
Pākē: 25 kgs / ʻeke a i ʻole e like me kāu noi.
E mālama: E kūʻai ma kahi wahi maloʻo.
Nā kūlana i hoʻokō ʻia: International Standard.
