Noi ka hana o HPMC
ʻO ka Hydroxypropyl methyl cellulose (HPMC) kahi ʻano o ka non-ionic cellulose ether, i hana ʻia me nā mea polymer kūlohelohe e like me nā mea maka a hoʻomaʻemaʻe ʻia e nā kaʻina hana kemika. I kēia lā e aʻo mākou e pili ana i ka hana noi o HPMC.
● Hiki ke hoʻoheheʻe ʻia ka wai: hiki ke hoʻoheheʻe ʻia i loko o ka wai i kēlā me kēia ʻāpana, ʻo ke kiʻekiʻe kiʻekiʻe e pili ana i ka viscosity, a ʻaʻole i hoʻopili ʻia ka dissolution e PH.l Organic solubility: HPMC hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe kūlohelohe a i ʻole nā mea hoʻonā wai wai e like me dichloroethane, ethanol solution, etc.
● Nā hiʻohiʻona gel wela: E ʻike ʻia ka gel hiki ke hoʻohuli ʻia ke hoʻomehana ʻia ko lākou wai wai i kekahi mahana, me ka hana hoʻonohonoho wikiwiki hiki ke kāohi.
● ʻAʻohe uku ionic: ʻO ka HPMC he cellulose ether non-ionic a ʻaʻole ia e paʻakikī me nā ion metala a i ʻole nā mea ola e hana ai i nā precipitates insoluble.
● Mānoanoa: He mānoanoa kona ʻōnaehana hoʻonā wai, a ʻo ka hopena mānoanoa e pili ana i kona viscosity, concentrate, a me ka ʻōnaehana.
● Paʻa wai: Hiki i ka HPMC a i ʻole kāna mea hoʻonā ke komo a mālama i ka wai.
● Hoʻokumu kiʻiʻoniʻoni: Hiki ke hana ʻia ka HPMC i kahi kiʻiʻoniʻoni ʻoniʻoni, paʻakikī, a elastic, a loaʻa iā ia ka momona maikaʻi a me ke kūpaʻa ʻana.
● Ke kū'ē i ka Enzyme: Loa'a i ka hopena o HPMC ke kū'ē enzyme maika'i a me ke kūpa'a viscosity maika'i.
● Paʻa PH: Paʻa ka HPMC i ka waikawa a me ka alkali, a ʻaʻole pili ka pH i ka laulā o 3-11. (10) Ka hana o ka ʻili: Hāʻawi ʻo HPMC i ka hana ʻili i ka hopena e hoʻokō i ka emulsification pono a me nā hopena colloid pale.
● Waiwai Anti-sagging: Hoʻohui ʻo HPMC i nā waiwai thixotropic system i ka pauka putty, mortar, tile glue, a me nā huahana ʻē aʻe, a loaʻa iā ia ka mana anti-sagging maikaʻi loa.
● Dispersibility: Hiki i ka HPMC ke hoʻemi i ka ʻāʻī ma waena o nā ʻāpana a hoʻopuehu like i ka māhele i hoʻopuehu ʻia i loko o nā droplet o ka nui kūpono.
● Adhesion: Hiki ke hoʻohanaʻia e like me ka mea hoʻopaʻa no ka nui o ka puaʻa: 370-380g / l³ pepa, a hiki ke hoʻohanaʻia i nā uhi a me nā mea hoʻopili.
● Lubricity: Hiki ke hoʻohana ʻia i loko o ka ʻōpala, asbestos, cement, a me nā huahana keramika e hōʻemi i ka friction a hoʻomaikaʻi i ka permeability o ka slurry concrete.
● Hoʻokuʻu: Hiki iā ia ke pale i nā ʻāpana paʻa mai ka ua a kāohi i ka hoʻokumu ʻana o ka ua.
● Emulsification: No ka mea hiki iā ia ke hoʻemi i ka ʻili a me ke ʻano o ka interfacial, hiki ke hoʻopaʻa i ka emulsion.
● Colloid pale: Hoʻokumu ʻia kahi papa pale ma luna o ka ʻili o nā droplets i hoʻopuehu ʻia e pale i nā kulu mai ka hui ʻana a me ka hoʻohui ʻana e hoʻokō i kahi hopena pale paʻa.
