Thaum gelation tshwm sim, cov kua nplaum los yog ntau dua cov kua nplaum polymer hloov mus rau hauv cov txheej txheem ntawm cov viscosity tsis kawg, piv txwv li cov gel Ib lub gel yuav suav tau tias yog ib qho elastic heev, roj hmab- zoo li khov. … Thaum txias, cov tshuaj rov gels. Kev tsim ntawm helices feem ntau tshwm sim thaum lub sij hawm gelation txheej txheem.
gelation tshuaj tiv thaiv yog dab tsi?
Gelation (gel hloov pauv) yog kev tsim cov gel los ntawm lub kaw lus nrog polymers… Thaum lub sijhawm ntawd hauv cov tshuaj tiv thaiv, uas txhais tau tias yog gel taw tes, lub kaw lus poob fluidity thiab viscosity yuav loj heev. Qhov pib ntawm gelation, los yog gel taw tes, yog nrog los ntawm kev nce siab ntawm viscosity.
txheej txheem gelling yog dab tsi?
Gels yuav raug categorized raws li qhov chaw ntawm cov gelling agents. … Cov txheej txheem ntawm gelling feem ntau muaj plaub kauj ruam: hydration ntawm tus neeg sawv cev gelling, sib tov nrog lwm cov khoom xyaw, cua sov ntawm cov sol thiab txias ntawm cov sol nyob rau hauv pwm kom cov gel teeb.
Yuav ua li cas cov gelation ntawm cov protein tshwm sim?
1.10.
Gelation phenomena tshwm sim thaum tsawg viscosity SLNs dispersion hloov dua siab tshiab rau hauv viscous gel. Cov txheej txheem tsim gel yog nrawm thiab tsis tuaj yeem pom. Cov txheej txheem yog irreversible thiab feem ntau cuam tshuam qhov poob ntawm colloidal particle loj.
piv txwv ntawm gelation yog dab tsi?
Piv txwv ntawm cov nyiaj tsis muaj zog ntawm lub cev yog cov ntawv cog lus hydrogen, thaiv copolymer micelles, thiab cov koom haum ionic. Ntawm qhov tod tes, tshuaj gelation cuam tshuam nrog tsim covalent bonds thiab ib txwm ua rau muaj zog gel. Peb cov txheej txheem tshuaj gelation tseem ceeb suav nrog condensation, vulcanisation, thiab ntxiv polymerisation
