Separate design Solar Pendant Light,Double Color Solar Pendant Light,Solar Shed Light,Outdoor Solar Warehouse Lights Shenzhen You&My Electronic Technology Co., Ltd , https://www.youmysolarlight.com
The battery of this item is not installed on the solar panel as traditional outdoor solar lights do, but on the lamp body. With 16.5 feet long wire, it can be used outdoors and indoors.
Connect/Disconnect for flexible use
Disconnect it from the solar panel after fully charged for 8 hours, and you will get a portable lamp. Could be used as temporary light source for camping or be hung anywhere light needed.
Wide applications, Suitable for outdoor & indoor
This solar motion sensor light is made of high-density ABS and IP65 waterproof materials, not easily worn by bad weather (high temperature/rain/snows). Suitable for places where no power supplied like gazebo, shed, workshop, patio, porch, garden, chicken coop, basement, storage, barn, garage, yard, carport, backyard, camp, driveway, greenhouse, loft, van, attic, awning, grill area, pergola, tent, cabin, etc.
How to make a transparent injection molded product?
To measure the transparency of some plastics , there are many standards, such as light transmittance, haze, refractive index birefringence and dispersion, etc., to see if the hardness and strength of the material are required. Transparent injection molding products, generally use PS, PMMA, SNA (AS) materials and other materials, but they all have a brittle problem that needs attention.
PS is a general-purpose plastic and the price is not higher than the price of PP (transparent). If the transparency of PP (crystalline material) is continuously increased, it is necessary to suppress crystallization during material preparation, so the cost is high.
According to the light transmittance of the material, it can be divided into:
Transparent material: the transmittance of visible light with a wavelength of 400nm-800 nm is above 80%;
Translucent material: light transmittance of visible light between 400 nm and 800 nm is between 50% and 80%;
Opaque material: 400 nm -800 nm visible light has a refractive index below 50%.
According to the above classification, the resin can be divided into transparent resin: mainly including PMMA, PC, PS, PET, PES, JD series, CR-39, SAN (also known as AS), TPX, HEMA, BS (also known as K resin). Etc.; Translucent resin: PP, PA; opaque resin: ABS, POM, PTFE, PF, etc.
Improve the principle of plastic transparency: reduce crystallinity, control clean quality, increase refractive index, and reduce birefringence.
Adding improved transparency of the plastic, a nucleating agent can be added, which is the most effective way to increase the transmittance of the transparent resin, which can promote the crystallization of small molecular substances. It can function as a nucleus in the resin.
Blending improves the transparency of plastics by adding other resins to the transparent resin to improve transparency.
The two-way stretching improves the transparency of the plastic, and can break the original crystal particles in the product to make the crystal size smaller, and achieve the purpose of improving the light transmittance.
