A backboard is a piece of basketball equipment. It is a raised vertical board with an attached basket consisting of a net suspended from a hoop. It is made of a flat, rigid piece of, often Plexiglas or tempered glass which also has the properties of safety glass when accidentally shattered.
Tempered glass; Tempered glass is easier to erase. Most tempered glass white boards have no frame. Polypropylene film; Polypropylene film is temporary and uses static electricity to cling to existing surfaces. It works with dry whiteboard markers and wipes. Whiteboards are reusable and materials are recyclable.
A hydrogel is a biphasic material, a mixture of porous and permeable solids and at least 10% of water or other interstitial fluid. [1] [2] The solid phase is a water insoluble three dimensional network of polymers, having absorbed a large amount of water or biological fluids.
Enamel is glass, not paint, so it does not fade under ultraviolet light. [28] A disadvantage of enamel is a tendency to crack or shatter when the substrate is stressed or bent, but modern enamels are relatively chip- and impact-resistant because of good thickness control and coefficients of thermal expansion well-matched to the metal.
Water-repellent glass (WRG) is a transparent coating film fabricated onto glass, enabling the glass to exhibit hydrophobicity and durability. [1] WRGs are often manufactured out of materials including derivatives from per- and polyfluoroalkyl substances (PFAS), tetraethylorthosilicate (TEOS), polydimethylsilicone (PDMS), and fluorocarbons .
Similarly, when the surface of chemically strengthened glass is deeply scratched, this area loses its additional strength. Another negative of chemically strengthened glass is the added cost. While tempered glass can be made cheaply through the fabrication process, chemically strengthened glass has a more expensive route to the market. These ...
This Rosco gel has a low transmittance at long wavelengths. There are also gels for color correction, such as CTB (color temperature blue) and CTO (color temperature orange). Color correction gels alter or correct the color temperature of a light to more closely match the color temperature of a film negative or the white balance of a digital ...
As a result of its safety and strength, tempered glass is used in a variety of demanding applications, including passenger vehicle windows, shower doors, architectural glass doors and tables, refrigerator trays, as a component of bulletproof glass, for diving masks, and various types of plates and cookware. In the United States, since 1977 ...
