When a toilet is flushed, the wastewater flows into a septic tank or sewage system and from there to a sewage treatment plant. A flush toilet may be colloquially called a lavatory, water closet (abbreviated W.C.), loo, comfort room (abbreviated C.R.), and many other names.
N verify (what is: Y/N?) Infobox references Polyvinylidene fluoride, or polyvinylidene difluoride (PVDF) is a highly non-reactive and pure thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. PVDF a synthetic resin produced by the polymerization of vinylidene fluoride (CH 2 =CF 2). A tough plastic that is resistant to flame, electricity, and attack by most chemicals,... Sigma-Aldrich offers Aldrich-427152, Poly(vinylidene fluoride) for your research needs.
Copolymers of PVDF are also used in piezoelectric and electrostrictive applications. One of the most commonly used copolymers is P(VDF-trifluoroethylene), usually available in ratios of about 50:50 wt% and 65:35 wt% (equivalent to about 56:44 mol% and 70:30 mol%).Another one is P(VDF-tetrafluoroethylene).VDF has a glass transition temperature (T g) of about â35 Â° C and is typically 50â60% crystalline. To give the material its piezoelectric properties, it is mechanically stretched to orient the molecular chains and then poled under tension.
