Thermosetting plastic - Plastics Wiki - 0 views

  • Thermosetting plastics (thermosets) refer to a variety of polymer materials that cure, through the addition of energy, to a stronger form.
  • Thermoset materials are usually liquid, powder, or malleable prior to curing, and designed to be molded into their final form, or used as adhesives.
  • The curing process transforms the resin into a plastic or rubber by cross-linking. Energy and catalysts are added that cause the molecular chains to link into a rigid, 3-D structure.

  • Thermoset materials are generally stronger than thermoplastic materials, and are also better suited to high-temperature applications. They do not lend themselves to recycling like thermoplastics, which can be melted and re-molded.
  • Examples Natural Rubber Bakelite, a Phenol Formaldehyde Resin (used in electrical insulators and plastic wear) Duroplast Urea-Formaldehyde Foam (used in plywood, particleboard and medium-density fibreboard) Melamine (used on worktop surfaces) Polyester Resin (used in glass-reinforced plastics/Fibreglass (GRP)) Epoxy Resin (used as an adhesive and in fibre reinforced plastics such as glass reinforced plastic and graphite-reinforced plastic)

Window on the Solid State - Unit Cell - 0 views

  • Note that the edges of these cells all connect lattice points in the structure, points with the same environments.
    • Justin Shorb
       
      Be sure that when you draw a unit cell, if you place the 'left' edge against the 'right' edge, they have the same lattice points touching!
  •  
    Helpful for Exam I #3
  •  
    Useful for understanding how Unit Cells work

Periodic Trends - Effective Nuclear Charge - 0 views

  • Slater's Rules
    • Justin Shorb
       
      Note that this is how you would calculate ENC - Although the nucleus gets MORE positive down the PT, the ENC actually decreases! Not just the compensation part, but actually in it's entirety.
  •  
    A good short synopsis of ENC
  •  
    Good for #8 Exam I

  • LIGHT: ITS SECRETS REVEALED
    • Justin Shorb
       
      This is a fairly large PDF file, but it has some good visual information!
  •  
    Great PDF talking about light. Good images of how to go from wavelength to sizes of various objects.
