Solar vacuum tube how to choose? Which is the best of the three tubes and the purple tube?
Do not listen to blow, give you a few strokes, with a lighter hit, dare to break is not broken the high boron silicon 3.4, which is the best material, or try to use a pipe to lift people can be a good selection of materials to process a good tube. The other is coating, copper, aluminum, steel three layer sputtering coating to ensure that the film does not fall off, fast absorption. The other is vacuum, the thermos bottle container, high vacuum insulation effect is good, a week down to 5 degrees Celsius, three high vacuum tube is ten minus four is one hundred times that of other vacuum tube. In addition, there are some details are the key factors affecting the life of the tube or the use of the results, you like cleaning, dust, etc.. Three executives of the industry is the most advanced processing, the above method can be tried.
Three high tube and the tube is the name of the vacuum tube, from the name is not good or bad. Judge good or bad, the key is to look at technology. Now on the market are generally high vacuum borosilicate glass 3.3, good and bad focus on the film and vacuum. The film technology uses well is better than the interference film, absorption and heat dissipation than gradient film. Of course, the quality of the interference film is also related to the manufacturer's technology, production and other aspects of the ability, it is recommended to choose big brands, more secure. Vacuum is also a very important factor to judge the quality of the vacuum tube, it determines the vacuum tube cooling capacity, the higher the vacuum, the more difficult to heat, the general vacuum tube can reach 0.0005Pa. You don't have to think about it if you don't get it.
Three high tube, the use of interference coating technology, mainly to see the vacuum tube, coating process, etc., it is important that the brand
