The basis of industry is raw materials. The price increase of raw materials directly affects the subsequent industrial development, so product prices will also rise. In the last period of time, some raw materials have risen, especially some metal materials, such as copper, aluminum and iron, which have risen by 38%, 37% and 30% respectively. This kind of increase is still very obvious. Affected by the increase in raw material prices, some industrial products have also begun to experience price increases. In addition, not only the price of metal materials has risen, but the prices of some non-metallic materials have also begun to rise. The more obvious ones are glass and plastics, which have risen by 35% and 30% respectively. This kind of increase is also very large in the past. , So the price of various raw materials has risen by more than 30%. Who is behind it and what is the impact?

A solar water heater is a device that converts sunlight into heat through a collector to heat water. The heater is usually installed in a sunny place and heats the water during the day. The water is stored in an insulated water storage tank for use when needed. The advantages of solar water heaters

When the global supply chain has been affected by the epidemic, the Suez Canal, which accounts for about 12% of global trade, has been interrupted and blocked, causing further pressure on the global supply chain. In recent months, there have been more and more container ships berthed in Los Angeles

The latest news comes from the blocked Suez Canal!At 4:40 on the 29th local time, the map showed that the position of the freighter on the Sesuiz Canal had been corrected, which had previously completely blocked both banks of the Suez Canal. The freighter that blocked the Suez Canal successfully res

The Suez Canal Authority stated on the 29th that the freighter Long Grant, which had been trapped in the Suez Canal for nearly a week, had successfully escaped its stranding. The Long Grant is about the size of the Empire State Building in New York, and after it ran aground last week, it paralyzed o

As the pace of urban construction is getting faster and faster, the floor construction is getting higher and higher. This is a good thing, but it will also have a certain impact on our water use. At this time, in order to ensure normal water use, we need to use it. The hot water has increased pump

Sunlight is a free and infinite source of energy. Solar energy does not produce air pollution or hazardous waste. Solar air conditioning makes sense because it is usually the hottest in the sun... and when air conditioning is most demanded! Switching to solar energy can cut your heating and cooling costs in half. With the spread of green energy and increased affordability, many homeowners are considering solar air conditioners over other cooling devices. Before you commit to using solar air conditioners, please understand what information is relevant to your final purchase decision.

A giant freighter operated by Taiwan Evergreen Shipping ran aground on the Suez Canal, which hindered this busy maritime trade route. Some analysts say that this may affect the transportation of oil, natural gas and other materials from the Middle East to Europe, and even affect the global supply ch

As a renewable energy source, solar energy is becoming more and more widely used in heating swimming pools. On the one hand, in order to solve the too high cost and environmental impact of traditional heating systems (such as gas boilers, oil boilers, electric boilers, etc.), it is more inclined to use clean, renewable solar energy to the swimming pool for heating. On the other hand, the solar heating system can be used both for heating the pool and for heating the swimming pool water for bathing. To a certain extent, reduce operating costs, and more economic and environmental benefits. https://www.1stsunflower.com/SFBP-Solar-Heating-For-Swimming-Pool-Spa-pd73435077.html

[Abstract] If you plan to install your first solar photovoltaic system on the roof, you may encounter problems with monocrystalline and polycrystalline silicon. The same purpose of poly and mono panels is to use energy from the sun and convert it into usable electrical energy. Both use additional si

The difference between single-phase and three-phase inverters in off-grid solar power system

The correct use of solar water heaters:To use solar water heaters correctly, the following aspects should be done:1. Fill up with water before using. During the service life of the water heater, it must be filled with water to avoid drying the solar water heater. Because the internal temperature of
