Recently, MIT author pointed out that its scientific research team obtained a formula, according to the formula in the glass production process to add specific materials, make the glass through the tensile force to obtain the corresponding light transmittance. Specifically, this material is called polydimethylsiloxane (dimethicone, also known as polydimethylsiloxane) and is a hydrophobic silicone material used in medicine, daily chemical products, food, construction and other fields. There are applications.

The characteristic of this material is that it normally has dark areas that are opaque to light but gradually become transparent when stretched. Then, the team began to calculate the light transmittance of this material at different doses and degrees of stretching, and explored the light transmittance formula of this material. Thus, as long as this material is added to the glass, the corresponding transparent effect can be obtained by the formula, and the “display” of the glass without electric driving can be realized.

Admittedly, this is a beautiful thing. However, the reality is always cruel. This kind of glass can be used in the window to achieve indoor temperature control, saving electricity, but the pressure on the glass to promote the polydimethylsiloxane in which the change in light transmittance, is the use of electricity?

Screws

The product range of Hongchuang hardware fasteners includes hexagon head screws, full thread and half thread hexagon socket head cap screws, hexagon wood screws, hexagon socket head cap screws, full thread and half thread hexagon socket countersunk head screws, hexagon socket head flange screws, set screws, etc. We provide products conforming to DIN, ANSI and JIS standards.

Stainless steel of grade 304 contains nickel of 8% and chromium of 18% and is the most commonly used grade for the production of fasteners. It possesses an excellent combination of strength, corrosion resistance and fabricability. Fasteners of this grade are being extensively used today in almost every industry.
