Car polishing refers to polishing the car before waxing, sealing or coating during car beauty. In the Car Cleaning and car washing industry, Car Wax and car polish are often used alternately. For ordinary people who want to polish their cars, it may be an expensive mistake not to distinguish between car wax and car polish. Polishing is a paint correction process to remove the defects on the surface of your car, while waxing is to lay a protective coating on the paint of the car as a detailed finish.
Car polish is a substance used to improve the appearance of a vehicle's exterior by removing minor scratches, swirl marks, and other imperfections. It is typically made of a combination of abrasive particles and oils or waxes that help to smooth out the surface of the paint and provide a protective layer. Car polish is applied using a soft cloth or polishing pad and is usually buffed off after it has dried to reveal a glossy, shiny finish. It is important to choose the right type of car polish for

As the issue of global greenhouse gas emissions is becoming more and more serious and approaching the critical point of self-regulation of the earth, countries have introduced relevant policies, and governments around the world, including China, must implement energy-saving emission reduction (CO2) without delay. LED lamps are currently the most energy-efficient. Green environmental protection electric light source has naturally become the main choice for lighting energy saving and emission reduction. With the gradual reduction of the cost and price of LED lamps, the popularity of the LED lamps is also accelerating. Before 2020, the market share of LED lamps will exceed 50.
Reducing the cost of LED lights LED chips occupy a major part of the cost of LED lights, so the main way to reduce the cost of LEDs is to reduce the cost of LED chips. The key to the development of LED chip technology lies in the substrate material and epitaxial growth technology. The base material is developed from traditional sapphire materials, silicon and silicon carbide to new materials such as zinc oxide and gallium nitride. In just a few years, LEDs have achieved great breakthroughs in light efficiency with a series of technological improvements including chip structure, surface roughening and multi-quantum well structure design.
The cost of silicon substrate is very low, and the technology is constantly improving. However, the current luminous efficiency is still not satisfactory. If this speed of development is maintained, once the higher level is reached, the silicon substrate becomes the most important technical solution and the enterprise will also become an inevitable choice. Gain huge economic returns.
Improve the light effect of LED lights LED lamp technology development direction with five major factors to improve light efficiency can also start from increasing the proportion of effective light. The thin film chip technology can reduce the light output loss of each side, and the light above 97 is output from the front side by the reflective surface at the bottom, so that most of the light obtained by the electric energy conversion is effective light, which not only significantly improves the light efficiency of the LED, but also Created superior convenience for lens design. Thin film chip technology is the core technology in the production of super bright LED chips.
Increasing the color rendering of LED lamps In high-brightness white LEDs, a small portion of the blue light has a longer wavelength after Stokes shift. This is a good thing because it allows LED lamp manufacturers to use many different color phosphor layers to extend the emission spectrum and effectively increase the color rendering index (CRI) of the LED. High CRI obtained with phosphor white LEDs comes at a price because Stokes shifts cause white LEDs to be less efficient than monochromatic LEDs. However, for most lighting applications, it is preferred to use high CRI and slightly less efficient LED lights.
