Nā ʻano huahana o ka hydroxypropyl methylcellulose no ke kūkulu ʻana

Hiki ke hoʻoheheʻe ʻia i ka wai a hiki ke hoʻoheheʻe ʻia kekahi mau mea hoʻoheheʻe organik i ka wai anuanu, ʻo kona ʻano kiʻekiʻe loa e hoʻoholo wale ʻia e ka viscosity, hoʻololi ka solubility me ka viscosity, ʻo ka haʻahaʻa o ka viscosity, ʻo ka nui o ka solubility.

Ke kūpaʻa paʻakai: ʻO ka Hydroxypropyl methylcellulose no ke kūkulu ʻana he ether cellulose non-ionic a ʻaʻole ia he polyelectrolyte, no laila he paʻa loa ia i loko o ka hopena wai ke loaʻa nā paʻakai metala a i ʻole nā ​​​​electrolytes organik, akā ʻo ka hoʻohui nui ʻana o nā electrolytes hiki ke hana i ka condensation Glue a me ka ua.

Hana ʻili: ma muli o ka hana ʻili o ka hopena wai, hiki ke hoʻohana ʻia ma ke ʻano he mea pale colloidal, emulsifier a me ka dispersant.

Ke hoʻomehana ʻia i kahi mahana, lilo ka hopena wai o ka hydroxypropyl methylcellulose no ke kūkulu ʻana i ka gel thermal i opaque, gels, a precipitates, akā ke hoʻomaʻalili mau ʻia, hoʻi ia i ke kūlana hopena mua, a hana ʻia kēia condensation. ʻO ka mahana o ke kāpili a me ka ua e hilinaʻi nui ʻia i kā lākou lubricants, suspending agents, protective colloids, emulsifiers, etc.

Nā Hiʻohiʻona Huahana

Anti-mildew: Loaʻa iā ia ka hiki ke pale aku i ka mildew a me ka paʻa maikaʻi o ka viscosity i ka wā mālama lōʻihi.

Paʻa PH: ʻAʻole i hoʻopilikia nui ʻia ka viscosity o ka hydroxypropyl methylcellulose aqueous solution no ke kūkulu ʻana e ka waikawa a i ʻole ka alkali, a he paʻa loa ka waiwai pH ma ka pae o 3.0 a 11.0. Paʻa ʻana i ke ʻano No ka mea, he mau waiwai viscoelastic kūikawā ka hydroxypropyl methylcellulose aqueous i hoʻopaʻa nui ʻia no ke kūkulu ʻana i hoʻohālikelike ʻia me nā solution aqueous o nā polymers ʻē aʻe, hiki i kona hoʻohui ke hoʻomaikaʻi i ka hiki ke mālama i ke ʻano o nā huahana seramika extruded.

Ka paʻa ʻana o ka wai: ʻo ka hydroxypropyl methylcellulose no ke kūkulu ʻana he hydrophilicity a me ka viscosity kiʻekiʻe o kāna hopena wai, he mea paʻa wai kiʻekiʻe.

Nā waiwai ʻē aʻe: mea hoʻomānoanoa, mea hana kiʻiʻoniʻoni, mea hoʻopaʻa, mea lubricant, mea hoʻokuʻu, colloid pale, emulsifier, a pēlā aku.
