Drying effect of temperature

When done properly, systematic studies of sol-gel synthesis and processing can facilitate the search for new materials, particularly silica aerogels, with desired properties such as low thermal conductivity, high optical transparency, improved mechanical properties, or reduced dust release behavior.

The effect of drying temperature on the surface hydroxyl concentration for Manosil VN3 slurried with 25 ml toluene and treated with excess Zr(7r-allyl)4 is shown in Figure 8. The discrepancy between these results and literature determinations of surface hydroxyl concentrations (20, 49, 50) prompted an investigation of the experimental technique. It was found that the concentration of the silica slurry had a profound effect on the degree of reaction with the organometallic. The results for Aerosil 380 dried at 200°C for 2 hrs under vacuum, slurried with toluene, and allowed to react with excess Zr(7r-allyl)4 or CH3MgI are shown in Figure... 

The effect of drying temperature on the available surface hydroxyl concentration of a silica is shown in Figure 8. A constant slurry concentration of 4% silica/toluene was used in these experiments. These results are comparable with other data (20, 62), and they indicate that the surface hydroxyl group concentration is reduced with increasing drying temperatures. The reaction of metal hydrocarbyl compounds with strained siloxane groups is illustrated in Reaction 4. 

To determine the effect of the aging of degraded starch and the effect of drying temperature, a series of tests were run In which fermentation age was varied from 7 to 40 days and drying from 20 C to 100 C (Table III), The relatively small variations observed In the data Indicated that neither aging nor temperature produced any significant effect on yarn properties.

The effects of drying temperature, bed thickness, and recycle ratio on water content and ascorbic acid/carotenoids retention were studied. Energy consumption per mass of water evaporated was evaluated considering only the energy used for heating ambient air to the inlet temperature. 

Two types of wood samples (namely Guilan spruce and pine) were selected for drying investigation. Natural defects such as knots, checks, splits, etc which would reduce strength of wood are avoided. All wood samples were dried to a moisture content of approximately 30%. The effect of drying temperature and drying modes on the surface roughness, hardness and color development of wood samples are evaluated.

The effect of drying temperature and pressure of Mg on the catalytic activity can be seen clearly by looking at Fig. 3 for polymerization runs at 5 atm. monomer pressure. As published before (22), silica dried at 600"C and having Isolated hydroxyl groups produce catalysts with higher activities, compared with those prepared on silica dried at 150 C. In both cases, acceleration-type kinetic curves were obtained with maximum activities (A ) of 2000 and 200 gPE x gTi x h x atm." respectively. 

The effect of drying temperature, nozzle gas mass flow, and suspension mass flow was studied for each investigated Suspension 1 and 2 using design of experiments (DoE).
