Resisting water, acid and alkali properties of the modified nano-silica-filled vulcanizes can be improved accordingly, and leaching liquor ion form vulcanizes decreases.

The films remain properties of both cardanol-formaldehyde resin and epoxy resin , which are acid-resisting , alkali-resisting and organic solvent-tolerant, and also have good service time.

The specific strength of titanium is high, and has a good corrosion resisting property in most mediums of acid, alkali, and salt service.
