Definitions

  • the temperature, the pH, the induced (sonic) energy, and the ratio of carbamaldehyde, alcohol, or DAA-to-the ratio of the precursor are among the most critical parameters which determine the characteristics of the resulting aerogel, e.g., the Kalgel aerogel. Those parameters control OH dissociation, hydrolysis, and polycondensation, and thus they can control the final characteristics of the resulting aerogel product.
  • the washed gel (e.g., alcogel) is then dried at a temperature of about 150 0 F (65.6 0 C) for about 6 hours, followed by drying at a temperature of about 220 0 F (104.4 0 C) for 6 hours, followed by drying (e.g., annealing of the aerogel) at a temperature of about 392 0 F (200 0 C) for up to 6 hours, e.g., typically between about 0.5-2 hours.
  • the dried product is collected and screened, per the specific requirements, to obtain the final nanogel.
  • one of the top, bottom and side walls 52, 54, 56, 58 is provided with an opening to facilitate filling of the internal volume of the insulating panel 50 with the aerogel and this opening is covered by a cover 66, after sufficient filling with the aerogel, to seal the aerogel therein.

Abstract

L'invention concerne un procédé à pression ambiante et à faible durée de cycle, pour la synthèse et la fabrication d'un nanogel hydrophile et hydrophobe, à base d'un métal de transition à faible densité, hautement isolant, hautement translucide, et à faible coût. Les aspects importants portent sur le procédé de synthèse, l'étape consistant à impartir une hydrophobicité, et le procédé de fabrication. Le procédé comprend les étapes de mélange d'une solution de précurseur refroidie avec une solution de catalyseur refroidie, de façon que le mélange présente un pH compris entre 9,5 et 12,2. Le mélange est maintenu à une température de 34 °F- 55 °F pendant 1 à 120 minutes, de manière à former un gel. Le gel est silylé pendant environ 120 minutes, lavé dans un fluide de lavage, puis séché et recuit pour former l'aérogel.
