Slippers are in great demand, and everyone has several pairs of slippers at home. In addition to their families' daily needs, people usually have several pairs of slippers at home for their guests. Since people usually wear slippers without socks, the soles of their feet and insoles are in direct contact, and the friction acts directly on the slippers when they walk. Therefore, the quality of slippers determines the length of their service life. The two primary materials of slippers on the market are EVA material and PVC; let's compare the two materials of slippers.

EVA slippers are ethylene (E) and vinyl acetate (VA) copolymer.

PVC slippers are PVC (polyvinyl chloride), plasticizers, foaming agents, and other additives.

EVA slipper's advantages: shock absorption, heat insulation, abrasion resistance and wear resistance, environmental protection and non-toxic, moisture-proof and anti-odor, good breathability, light on the feet.

PVC slippers advantages: soft shoes, comfortable to wear, excellent plasticity, the anti-slip effect is better, also not easy to get dust, cheap.

EVA slippers disadvantages: the material is more slippery (now EVA slippers bottom will take anti-slip measures to increase the anti-slip performance)

PVC slippers disadvantages: strict operation process, complex process, low production efficiency (and evil businessmen are using poor quality materials, the odor is heavy)

In terms of material, EVA slippers are more durable than PVC shoes, comprehensive advantages and disadvantages; EVA slippers are more suitable for people to use, but the price of EVA slippers is higher than PVC slippers, so it depends on the budget and needs of different products.

Translated with www.DeepL.com/Translator (free version), Solar energy is the cleanest energy globally, pollution-free, renewable, and solar panels that can use solar energy also have many advantages. Why do we say that solar panels are energy-saving and environmentally friendly? That's because solar panels can absorb the energy in sunlight and convert it into usable energy, and in this process, they will not produce any harmful substances to the environment.

Here are five advantages of solar panels:

The use of sunlight to generate electricity is inexhaustible and inexhaustible

The operating principle of solar panels is to absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. The primary material of most solar panels on the market is "silicon." The use of sunlight started a long time ago, and the sunlight is inexhaustible.

Solar panels are suitable for the ecological environment.

Solar panels are made of crystalline silicon, the most common type of silica sand. Although some chemicals are used to clean up the semiconductor appearance of the system during production, the leading photovoltaic industry manufacturers strictly abide by environmental regulations and comply with industry waste disposal rules to ensure that they will not cause continuous damage to the health of workers and the ecological environment.

Fossil fuels such as coal, oil, and natural gas are highly polluted because they release chemical substances and harmful elements into the atmosphere when excavated, drilled, or transported. The use of solar panels to generate electricity is very environmentally friendly.

Solar panels slow down climate change.

The use of conventional energy to generate electricity will release a lot of carbon dioxide and greenhouse gases, absorb heat in the atmosphere and increase the surface temperature, and the fuel source of solar panels for power generation is sunlight, so the use of solar charging panels for power generation is an ideal choice for reducing pollution.

Some solar panels and photovoltaic modules use solar energy and high-efficiency energy systems to reduce carbon emissions during the production stage.

Solar panels will not cause water problems.

Water is the basic need of human beings, and water resources are scarce and precious in many drought and turbulent areas. Solar panels use sunlight to generate electricity and will not cause water problems. According to the United Nations Water Mechanism, agriculture requires the most water globally.

Biofuels are called clean fuels by some people. They consume a lot of water resources in irrigation and material processing, and in some cases, have caused people's resistance to land use and water use. Hydropower stations are also called clean power sources and are widely used as renewable energy sources.

Solar panels are as quiet as sunlight and have no noise.

Although wind turbines perform well in terms of power supply, they generate a lot of noise during work. Residents living near wind power plants have a solid reaction to noise, and many people will still not adapt even after a long time. As there are no collisions and noises caused by moving parts, photovoltaic modules of solar panels will not be considered a public hazard.

These prove that solar panels are greener and cleaner than other renewable energy sources in production, operation, environmental impact, and emissions.
