He aha ka ʻokoʻa ma waena o HPMC E a me K?

ʻO HPMC (Hydroxypropyl Methylcellulose) kahi ʻano cellulose ether i hoʻohana ʻia i nā ʻano noi like ʻole, me nā lāʻau lapaʻau, nā meaʻai, nā mea hoʻonaninani, a me ke kūkulu ʻana.ʻO ka HPMC he polymer non-ionic, hiki ke hoʻoheheʻe ʻia i ka wai mai ka cellulose, a loaʻa i nā ʻano ʻelua: HPMC E a me HPMC K.

ʻO HPMC E kahi papa haʻahaʻa viscosity o HPMC, a hoʻohana nui ʻia i nā noi lāʻau.Hoʻohana ʻia ia ma ke ʻano he mea hoʻopaʻa, disintegrant, a me ka suspending agent i nā papa, capsules, a me nā granules.Hoʻohana ʻia ia ma ke ʻano he mānoanoa i nā syrups, creams, a me nā ʻaila.ʻO ka HPMC E he haʻahaʻa viscosity haʻahaʻa, ʻo ia hoʻi he haʻahaʻa viscosity ke hoʻoheheʻe ʻia i ka wai.He mea kūpono kēia no ka hoʻohana ʻana i nā lāʻau lapaʻau, no ka mea he maʻalahi ka hui ʻana a hoʻopuehu i ka wai.

ʻO ka HPMC K he papa kiʻekiʻe-viscosity o HPMC, a hoʻohana nui ʻia i ke kūkulu ʻana a me nā noi meaʻai.Hoʻohana ʻia ia ma ke ʻano he mea hoʻopaʻa, mānoanoa, a me ka mea hoʻopaneʻe i nā mea hana, e like me nā tile adhesives, grouts, a me nā plasters.Hoʻohana ʻia ʻo ia ma ke ʻano he mea mānoanoa i nā huahana meaʻai, e like me nā jams, jellies, a me nā kīʻaha.ʻO ka HPMC K he papa viscosity kiʻekiʻe, ʻo ia hoʻi, he viscosity kiʻekiʻe ke hoʻoheheʻe ʻia i ka wai.ʻO kēia ka mea kūpono no ka hoʻohana ʻana i ke kūkulu ʻana a me nā noi meaʻai, no ka mea hiki iā ia ke hāʻawi i kahi mānoanoa, viscous kūlike.

ʻO ka ʻokoʻa nui ma waena o HPMC E a me HPMC K ka viscosity.ʻO ka HPMC E he haʻahaʻa viscosity haʻahaʻa, ʻo ia hoʻi he haʻahaʻa viscosity ke hoʻoheheʻe ʻia i ka wai.He mea kūpono kēia no ka hoʻohana ʻana i nā lāʻau lapaʻau, no ka mea he maʻalahi ka hui ʻana a hoʻopuehu i ka wai.ʻO ka HPMC K he papa viscosity kiʻekiʻe, ʻo ia hoʻi, he viscosity kiʻekiʻe ke hoʻoheheʻe ʻia i ka wai.ʻO kēia ka mea kūpono no ka hoʻohana ʻana i ke kūkulu ʻana a me nā noi meaʻai, no ka mea hiki iā ia ke hāʻawi i kahi mānoanoa, ʻano like ʻole.

Ma waho aʻe o ka viscosity, ʻokoʻa ka HPMC E a me HPMC K ma ke ʻano o kā lākou hana kemika.He haʻahaʻa koʻikoʻi ko HPMC E ma mua o HPMC K, e hāʻawi ana i ka viscosity haʻahaʻa.Loaʻa i ka HPMC K ke kaumaha molekala kiʻekiʻe, e hāʻawi iā ia i kahi viscosity kiʻekiʻe.

ʻO ka hope, ʻokoʻa ka HPMC E a me ka HPMC K ma ke ʻano o ko lākou solubility.Hiki ke hoʻoheheʻe ʻia ka HPMC E i ka wai anuanu, ʻoiai ʻo HPMC K e hoʻoheheʻe ʻia i ka wai wela.ʻO kēia ka HPMC E kūpono no ka hoʻohana ʻana i nā noi lāʻau lapaʻau, no ka mea hiki ke hoʻohui maʻalahi a hoʻopuehu ʻia i ka wai anuanu.He kūpono ka HPMC K no ka hoʻohana ʻana i ke kūkulu ʻana a me nā noi meaʻai, no ka mea hiki ke maʻalahi a hoʻopuehu ʻia i ka wai wela.

I ka hopena, ʻo ka ʻokoʻa nui ma waena o HPMC E a me HPMC K ka viscosity.ʻO ka HPMC E he haʻahaʻa haʻahaʻa haʻahaʻa, ʻoiai ʻo HPMC K he māka kiʻekiʻe-viscosity.Eia hou, HPMC E he haʻahaʻa molekala kaumaha ma mua o HPMC K, a hiki ke hoʻoheheʻe 'ia i loko o ka wai anuanu, oiai HPMC K i ka wai wela.Hana kēia mau ʻokoʻa iā HPMC E a me HPMC K i kūpono no ka hoʻohana ʻana i nā noi like ʻole.
