The present invention relates to a kind of gas phase steam trap connection, belong to aeroge preparing technical field.
Background technology
Aerosil is a kind of is decentralized medium with gas, is mutually built up the nano-porous materials formed, have the feature of low-density, high porosity and high-specific surface area by silica colloidal particles.The skeleton structure that aeroge is made up of nano-scale particle significantly can reduce the solid state heat conduction of material; Its nanoaperture diameter is less than the mean free path of gas molecule, can limit gas molecule heat transfer, and therefore the thermal conductivity of aeroge is lower than the thermal conductivity of still air, is the solid material that current known heat-proof quality is the most excellent.
Many results of study show, when the hole diameter in material is less than 60nm, when being namely less than the freedom of motion journey of air molecule, the air molecule in hole loses free-moving ability, is attached on nanometer hole wall.Aerogel material is made all to have the thermal conductivity lower than still air at high temperature and normal temperature.
Aeroge surface prepared by universal method is containing a large amount of hydroxyls, cause the aerogel material easy moisture absorption in atmosphere, chance aqueous water produces huge capillary force and causes nanometer structure collapse, fragmentation, have impact on its physical property, thus significantly limit the application of aeroge, have impact on SiO
2applying of aeroge.Large quantity research shows, obtains hydrophobic surface by carrying out methyl-monosilane modification to gel, can avoid the mutual condensation between gel pore surface hydroxyl and the irreversible contraction caused.Generally speaking, the water in wet gel first will be removed by solvent swap step.SiO
2containing a large amount of water (60% ~ 90%) in wet gel, need the water removed with the diffusion of a large amount of solvents in nano-pore in gel three-dimensional network, the validity that guarantee modifier reacts the hydroxyl modification of gel surface.But the solvent of this method at substantial and hydrophobic reagent, the hydrophobic grouping quantity of introducing is uncontrollable.Also improve production cost, high-temperature hot unstable properties simultaneously.
It is directly hydrophobic that patent CN201080030822.4 provides a kind of wet gel, and manufacture method and the manufacturing installation of aeroge.After cancellated basket is put into reactor, wet gel is put in basket, at reactor lower part, ultrasonic wave maker is installed, and promote that reaction is carried out from bottom introducing nitrogen, be modified as the aeroge of hydrophobization at short notice.This reaction is carried out at normal temperature and pressure.Adopt hydrophobic reagent (as: n-butanol, n-amyl alcohol, n-hexane), and add the silane compound of 5-10%, and reflux in the reactor, finally produce the aeroge of hydrophobization.
