Chapter 80: The Problem of Testing

Chapter 80 Experimental Questions

The finished embroidery and spinning work on the Canton Fair side is in progress, Jiang Tingting went to Guangzhou to gather people, and Shen Qiuyun is also refining the drawings, and the embroidery pattern in the middle has been fine-tuned according to Huang He's later opinions.

Liao Muping's research and development of "hot fast" is also progressing almost, and it is expected to be completed tomorrow, and when Huang He arrived at the research room, Liao Muping was installing the hot spiral ring.

The heating spiral is usually made of a thin metal tube, which is equipped with a heating wire, and then poured into an insulating material such as magnesium oxide powder to encapsulate and fix the heating wire in the middle of the tube, so that it does not contact with the pipe wall, and the two ends of the heating wire are connected with the power cord respectively. When energized, an electric current flows through the heating wire, which heats up.

This principle was seen in an industrial magazine in Huang He's previous life, and he wrote it down when he thought it was interesting, but he didn't expect it to be of great use in this life.

Liao Muping was loading the heating wire, and when he saw Huang He coming, he handed the heating wire to Huang He, and raised a few questions of his own.

"Director Huang, I use a nickel-iron alloy of equal power and thickness according to your requirements, but there is a problem, will this alloy wire be too thin, and the melting point will be too low if iron is selected, if heated, the composition of iron in it is easy to melt at high temperature, and it is easy to rust and oxidize when exposed to water. ”

Huang He took the heating wire in his hand and looked at it for a while, and said: "What if the 'hot fast' is immersed in the liquid? The heat will be quickly dissipated through the liquid, so that the liquid will be heated quickly, and the heating wire will not be burned out." Naturally, if the 'hot fast' is allowed to dry burn in the air, the heat is not easy to dissipate, and the metal outer tube will quickly scorch, or even burn red, and the heating wire in the tube will burn off. But who has nothing to do with dry burning, you said that this problem has been considered before, so our products, when using, will make an instruction manual, clearly tell the user to put the "hot fast" into the liquid first, the liquid should at least submerge the heating spiral, but the handle and wire can not be immersed in the liquid, and then turn on the power. After heating, you should also disconnect the power supply first, and after a while, after a while, after the temperature of "hot fast" is reduced, then take it out of the liquid, pay attention to dry the collection, so that you can greatly improve the service life of hot fast. ”

"Even so, if you use it for a long time, according to the current water quality problem, it is easy to produce scale, will the scale affect the heating of the nickel-iron alloy wire, and it will not take long to be unusable?" Liao Muping is a little worried that the service life of the finished product will not be long enough, which will lead to a series of sales problems, if these problems are manifested later, consumers make a fuss, it will be an uncontrollable event, and when the time comes, it will be more difficult to re-establish the product image than to ascend to the sky.

Hearing this, Huang He smiled, and he knew what Professor Liao was worried about, "Naturally, the heating wire in 'Heat Fast' is a filament made of nickel-iron alloy, which is generally brittle and easy to break. Therefore, "hot fast" should not be violently vibrate, and if there is limescale or buildup on the surface, it can be gently brushed off with a small brush, and should not be knocked with a hard object or scraped with a knife. "Heat fast" once the broken wire can not be repaired, only a new one, you said the life problem, at this stage does need to be adjusted, compared with those household appliances, "hot fast" use is indeed shorter. So what if I only sell it for 15 yuan a piece? 15 a piece, but the service life is more than one to two years, isn't that enough?"

"15 pieces?" Liao Muping was a little surprised, Huang He's product innovation is absolutely possible, greatly improving the convenience of boiling water, not much electricity, and high efficiency, fast burning, don't worry about no hot water in winter, because of the development of buildings in Shuzhong, many ordinary people can not use hot water in winter, this is definitely a good sales opportunity. Besides, the salary he asked himself to come over was really heaven and earth compared to the money for this one thing, "Isn't it too little to sell so cheap, as far as I know, there is no research on this in the market now, why don't you take this opportunity to raise the price a little higher?"

"Small profits but quick turnover, have you ever heard of cheap and easy-to-use things, who is not happy to buy them. Huang He paused and continued, "Do you know how many people there are in China now? 118517 million people, if I raise the price, according to China's current economic development, I will lose two-thirds of the source of customers, but now I only need fifteen yuan, I can buy a convenient thing to boil water, use it for two years, you can do this business or not, so that even if only one thousandth of people buy my products, it can also earn more than one million, what is the cost, this Professor Liao is developing, there should be a number in my heart, as for why the service life is controlled between one and two years, this ideal must Professor Liao can also figure it out, two years of generation, circular sales, now we are just a start, if it is in the later stageWhen the economy starts to come up, we can carry out the next step of research and development, and it is not too late to raise the price at that time. ”

Liao Muping listened to Huang He's words, and was a little impressed by Huang He, he just thought that the young man was high-spirited, but he didn't expect Huang He to know so many twists and turns at a young age, but only Huang He himself knew where to learn these things, which was really deserved.

Huang He remembered the "hot fast" fire and murder incident in his previous life, and said: "This thing does have some problems and defects, once the quality of 'hot fast' cannot be guaranteed, and the workers below make mistakes, it is extremely easy to cause safety accidents." There are also some people who may often forget the use time of the hot fast, this product does not have a timing or high temperature dormancy function at this stage, it is afraid that the water has not been pulled out after boiling, causing a fire, but this is the problem we need to solve in the future, at this stage we will develop the product first, and then talk about other problems after testing. ”

Liao Muping listened to Huang He's passionate passion, such a small thing, but it is the way to make a fortune, he has been a physics teacher for so many years, and he only knows how to read dead books, it seems that the times are different, and now it is the world of a new generation of young people.
