Iyo nzira yekuparadzanisa gel yekuparadzanisa serum neropa

The mechanism ofkupatsanura gel

Iyo serum yekuparadzanisa gel inoumbwa nehydrophobic organic compounds uye silica poda.Ndiyo thixotropic mucus colloid.Chimiro chayo chine nhamba huru yehydrogen zvisungo.Nekuda kwekubatana kwehydrogen bonds, network network inoumbwa.Pasi pechiito che centrifugal simba, network network inoparadzwa uye inoshandurwa.Kune mvura ine yakaderera viscosity, kana iyo centrifugal simba inonyangarika, inoumbazve network network, iyo inonzi thixotropy.Ndiko kuti, pasi pemamiriro ekupisa nguva dzose, imwe simba remagetsi rinoshandiswa kune mucus colloid, iyo inogona kuchinja kubva kune yakakwirira-viscosity gel state kusvika kune yakaderera-viscosity sol state, uye kana simba remagetsi rinopera, richadzokera kune iyo yepakutanga yepamusoro-viscosity gel state.Chiitiko chegel uye sol interconversion chinokonzerwa nekuita kwemasimba masimba chakatanga kutumidzwa na Freundlich naPetrifi.Sei kuwirirana pakati pe gel ne sol kuchiitika nekuda kwekuita kwe mechanical force?Thixotropy imhaka yekuti chimiro chegeri chinoparadzanisa chine nhamba huru ye hydrogen bond network structures.Kunyanya, iyo hydrogen bond haisi kungogadzira imwechete covalent bond, asi zvakare inoumba isina kusimba hydrogen bond nemamwe mamorekuru anopomerwa zvisina kunaka pasi pemamwe mamiriro.Patembiricha yemumba, iyo hydrogen bond iri nyore kudimburwa kuti ikonzere kusanganiswa.Iyo silica surface ine silyl hydroxyl mapoka (SiOH) kuti iite SiO molecular aggregates (primary particles), ayo akabatanidzwa nehydrogen bonds kuti aite cheni-yakafanana zvidimbu.Iyo cheni silica particles uye zvimedu zvehydrophobic organic compound inoumba iyo inoparadzanisa gel inowedzera kuumba hydrogen zvisungo kugadzira network chimiro uye kuumba gel mamorekuru ane thixotropy.

Iyo chaiyo giravhiti yejeru yekuparadzanisa inochengetedzwa pa1.05, iyo chaiyo giravhiti yeserum inenge 1.02, uye iyo chaiyo giravhiti yeropa clot inenge 1.08.Kana gel rekuparadzanisa neropa rakabatana zviri centrifuged mune imwechete test tube, hydrogen chain network structure mu silica aggregate inokonzerwa ne centrifugal force inoshandiswa kune gel inoparadzanisa.Mushure mekuparadzwa, inova chimiro-chetani, uye gel rinoparadzanisa rinova chinhu chine viscosity yakaderera.Ropa reropa rinorema kudarika gel rinoparadzanisa rinofamba kusvika pasi pechubhu, uye gel rinoparadzanisa rinodzokera shure, richiita zvikamu zvitatu zveropa rekuvhara / kupatsanura gel / serum pasi pechubhu.Kana iyo centrifuge ikamira kutenderera uye ichirasikirwa ne centrifugal simba, cheni zvidimbu zve silica aggregates mugeri rekuparadzanisa zvinogadzira network network zvakare nemabhondi ehydrogen, inodzoreredza yekutanga high viscosity gel state, uye kugadzira yekuzviparadzanisa pakati pemagwamba eropa serum.
