ʻO ke ʻano o ka hoʻokaʻawale ʻana i ka gel no ka hoʻokaʻawale ʻana i ka serum a me ke koko

ʻO ka mīkini ohoʻokaʻawale gel

Hoʻokumu ʻia ka serum separation gel me nā pūhui organik hydrophobic a me ka pauka silica.He thixotropic mucus colloid.Aia i loko o kona hale ka nui o nā paʻa hydrogen.Ma muli o ka hui ʻana o nā paʻa hydrogen, ua hoʻokumu ʻia kahi ʻōnaehana pūnaewele.Ma lalo o ka hana o ka ikaika centrifugal, ua luku ʻia ka ʻōnaehana pūnaewele a hoʻololi ʻia.No ka wai me ka viscosity haʻahaʻa, i ka wā e nalowale ai ka ikaika centrifugal, hana hou ia i kahi ʻōnaehana pūnaewele, i kapa ʻia ʻo thixotropy.ʻO ia hoʻi, ma lalo o ke kūlana o ka mahana mau, ua hoʻohana ʻia kekahi ikaika mechanical i ka mucus colloid, hiki ke hoʻololi mai kahi kūlana gel viscosity kiʻekiʻe i kahi mokuʻāina haʻahaʻa-viscosity sol, a inā e nalowale ka ikaika mechanical, e hoʻi ia i ka. ke kūlana gel kiʻekiʻe-viscosity kumu.ʻO ka hanana o ka gel a me ka sol interconversion i loaʻa mai ka hana o nā mana mechanical i kapa mua ʻia e Freundlich a me Petrifi.No ke aha i hana ai ka pilina ma waena o ka gel a me ka sol ma muli o ka hana o ka ikaika mechanical?ʻO Thixotropy no ka mea ʻo ke ʻano o ka gel hoʻokaʻawale i loaʻa i ka nui o nā hale pūnaewele paʻa hydrogen.ʻO ke kikoʻī, ʻaʻole i hoʻokumu wale ka paʻa hydrogen i hoʻokahi paʻa covalent hoʻokahi, akā hana pū kekahi i kahi paʻa hydrogen nāwaliwali me nā molekole i hoʻopiʻi maikaʻi ʻia ma lalo o kekahi mau kūlana.Ma ka lumi wela, ua maʻalahi ka ʻoki ʻana i ka paʻa hydrogen i mea e hoʻohui hou ai.ʻO ka ʻili silica he mau hui hydroxyl (SiOH) e hana i nā ʻāpana molekala SiO (nā ʻāpana mua), i hoʻopili ʻia e nā paʻa hydrogen e hana i nā ʻāpana like me ke kaulahao.ʻO nā ʻāpana silica kaulahao a me nā ʻāpana o ka pūhui organik hydrophobic e hoʻokaʻawale ana i ka gel hoʻokaʻawale e hana hou i nā paʻa hydrogen e hana i kahi ʻōnaehana pūnaewele a hoʻokumu i nā molekala gel me ka thixotropy.

ʻO ka'umekaumaha kiko'ī o ka gel hoʻokaʻawale e mālamaʻia ma 1.05,ʻo ka'umekaumaha kiko'ī o ka serum e pili ana i 1.02, aʻo ka'umekaumaha o ke koko koko e pili ana i 1.08.Ke hoʻokaʻawale ʻia ka gel hoʻokaʻawale a me ke koko coagulated i loko o ka pahu hoʻāʻo hoʻokahi, ʻo ka ʻōnaehana kaulahao hydrogen i loko o ka silica aggregate ke kumu o ka ikaika centrifugal i hoʻopili ʻia i ka gel hoʻokaʻawale.Ma hope o ka luku ʻia ʻana, lilo ia i mea like me ke kaulahao, a lilo ka gel hoʻokaʻawale i mea waiwai me ka viscosity haʻahaʻa.ʻOi aku ke kaumaha o ke koko ma mua o ka gel hoʻokaʻawale i lalo o ka paipu, a hoʻohuli ʻia ka gel hoʻokaʻawale, e hana ana i ʻekolu papa o ke koko koko/separating gel/serum ma lalo o ka paipu.I ka pau ana o ka wiliwili ana o ka centrifuge a lilo ka ikaika centrifugal, e houluulu na mea kaulahao o ka silica aggregates i loko o ka separation gel i mea hoohana hou ia e ka hydrogen bonds, e ho'iho'i hou i ke kūlana ki'eki'e viscosity gel mua, a hana i kahi papa kaawale ma waena o nā koko koko i loko o ka pahu. serum.
