Anhydrous calcium sulfate crystallization kinetics of transformation
8 NaCL concentration, the experimental results are in l5C and 20 \NaC1 concentration and the concentration of l0 of the difference is small,air jordan shoes cheap, the late response. 5 NaCI concentration in the velocity of the water slightly faster - more. Theory to explain by crystal hydration rate of CaSO4 concentration appeared optimal NaCI good agreement with the experimental results. 3.5.2 When the NaC1 concentration was higher than l0 time, △ c with the increase of NaCI concentration significantly reduced,air jordans, hydration significantly reduced ability to promote 20,ugg milano, and thus,ed hardy clothing, the water table significantly reduced the rate of reaction. 4CaSO4 NaC1 solution in the hydration kinetic data were fitted by computer fitting the l5c, 2Oc and 39'C when the C-~ O4 in the NaCI solution in the hydration kinetics model for the experimental data,ugg prezzo, the model of mathematical expressions the time when T = 188.15K to 0 =-- 299.12085fc a 0.076l +546.36955 C ~ +17.87024 ~ when T = 293. i5K when o =-- 98.4329lc-o. 078lT +13.77596 ~ time when T = 303.15K. 0 =-- 80.47469lc a 0.078lT +. 38309--: 0.06822 where 0-'-C-DSO ・ converted into CaSO ・ ・ 2H0 conversion rate (calculated) C - NaCI concentration for a reaction time of the experimental data and calculated the average deviation of l0 time, CaSO a hydration rate increases with the NaCl concentration increased slow Reference 1It.
