  Domestic living standards are getting higher and higher. More and more people buy villas and large balcony rooms to enjoy the time of bathing in the sun, but they will be troubled by a problem: what kind of material should be used for balcony tables and chairs? The problem that needs to be considered when choosing balcony tables and chairs is that balcony furniture is vulnerable to wind, sun, and rain. Therefore, the choice of material is different.     Therefore, the material requirements for balcony tables and chairs  are generally higher than those for indoor furniture. Generally, balcony tables and chairs made of teak, cast aluminum, and imitation rattan are selected.         Balcony tables and chairs I personally recommend using rattan-like balcony tables and chairs. The general imitation rattan is made of PE rattan, which is easy to clean, has a smooth surface and strong toughness. The exquisite modern technology makes the lines of the imi...

  Power socket principle : The power socket relies on electric touch to transmit electric energy, and the transmission of electric energy will inevitably lead to a rise in the temperature of the plug and socket combination.   Provided that the temperature increase under full load complies with the upper value of the technical parameter rules, the plug and socket combination works stably when transmitting electrical energy.         For example, the general air conditioner indoor unit has an emergency switch, which is to check the quality of the air conditioner remote control. If the emergency switch can turn on the power, you should choose to replace the remote control. The power socket is cut off or the power cord is disconnected.   Of course, not all electrical equipment uses DC power. Alternating current is used in many appliances, household appliances, notably lamps, washing machines and refrigerators, and is delivered directly from the grid through...

  According to the statistics of the Food and Agriculture Organization of the United Nations, about 1.3 billion tons of food for human consumption are discarded or wasted before reaching the table every year in the world, which is equivalent to 1/3 of the total food production.   About 14 percent of food is lost in transit, 5 percent is thrown away from restaurants, and 2 percent is thrown away from retail outlets.   Dairy products, fruit and vegetables are among the products that require the most special care during transportation and distribution. And all food needs to be properly transported and stored, under strong protection and suitable temperature, in order to reach the destination smoothly. Otherwise, they become wasted 1/3.                     Serious challenges   The production and transportation of food requires vast resources such as water and energy. Wasted food accounts...

  With the implementation of my country's sustainable development strategy, the proportion of compressed natural gas ( CNG ) and liquefied petroleum gas (LPG) as economical and practical green fuels in my country's energy consumption has grown rapidly. The use of clean fuels such as CNG and LPG in place of conventional fuels by automobiles (mainly buses and taxis) has been a national key project since the "Tenth Five-Year Plan" period. Large cities with serious pollution are fully promoted. During the promotion of clean fuel, some problems related to lubricating oil also appeared, which aroused the attention of users. For example, the original engine oil is still used in the refitted vehicle engine, which often has more carbon deposits, more sludge, and shorter oil change intervals. , The engine is prone to many problems such as early wear and tear and shortened overhaul mileage. Here we briefly analyze and introduce these phenomena and countermeasures.      ...
