Chapter 163: PY transaction

　　 It seems that searching on the Internet does not work this way.
　　 In fact, Xu Qiu originally had concerns about this approach.
　　Because it is difficult to know the roots of the manufacturers, they may go bankrupt one day and run away. Most domestic companies have only a few years of life.
　　 It’s okay to buy an oil bath for a few hundred yuan. This instrument worth tens of thousands of yuan is bought online. If you encounter after-sales problems later, it will be very troublesome.
　　 It seems that I can only find offline channels.
　　 Offline channels, how can I find them?
　　 Xu Qiu asked Chen Wanqing next to him tentatively:
　　 "Senior sister, do you have a channel to buy a heating glue machine?"
　　 "No, there don't seem to be many domestic manufacturers doing this," Chen Wanqing shook her head and said:
　　 "I will send a message to the sales of several optoelectronic materials companies and ask, but don't hope too much."
　　 "This can only be done." Xu Qiu said.
　　 This is difficult. If you can't buy ready-made instruments, is it possible to learn Duan Yun and DIY an instrument yourself?
　　 is not bad, but considering the time cost, it is not a good choice.
　　Moreover, someone in the literature used this kind of glue spreader with heating function, indicating that this kind of instrument must exist.
　　 It's just that they didn't give the model of the instrument in the experimental part.
　　 I don’t know if they forgot to write, or some other reason.
　　……
　　 Just as Xu Qiu was tangled, the sound of Teacher Wei's leather shoes suddenly came from the corridor.
　　 A few seconds later, Wei Xingsi appeared at door 216.
　　 It looks like he should have just returned from the outside, passing through the laboratory, and making routine inspections.
As soon as 　　 entered the door, he saw Xu Qiu staring at the computer screen in a daze, and asked:
　　 "What are you up to?"
　　 Now that Teacher Wei asked, Xu Qiu simply told the truth directly:
　　"My P4T derivative system requires a special spin coating method, thermal spin coating method, to obtain high photoelectric performance.
　　 The basic principle is to maintain a high temperature environment during the spin coating process, such as 100 degrees Celsius.
　　 But our current ordinary glue spreading machine cannot realize this process. It can only simulate approximately, heating the solution and the substrate to the temperature we need, and then spin coating quickly.
　　 However, the operation of this method is very difficult and rough, and the actual conditions of spin coating will be slightly different each time.
　　 I’m thinking, if you buy a homogenizer that integrates constant temperature heating, it will be much more convenient to do related experiments and the data stability will also be improved. "
　　 "Then buy it, at what price?" Teacher Wei said.
　　 "It's estimated to be tens of thousands of yuan, but I searched on the Internet, but I didn't find the relevant manufacturer." Xu Qiu looked in the direction of Chen Wanqing and continued:
　　 "I beg Chen Wanqing, senior sister, to find some optoelectronic materials companies to ask, it is the companies we usually buy monomers and polymers, they..."
　　 After finishing speaking, he winked at the senior sister.
　　 Chen Wanqing understood, and said:
　　 "I asked five companies, and three of them responded, saying that there are no relevant channels, and the other two have not yet responded to me. I guess..."
　　 Teacher Wei interrupted:
　　 "Okay, I see, I will solve it, Xu Qiu, come with me."
　　……
　　 218 room.
　　 After Wei Xingsi entered the door, he took out two bottles of Nongfu Sanquan from under the coffee table, unscrewed the cap and poured it into the kettle, and said:
　　 "The heating and homogenizing machine you mentioned just now, is the suction table of the ordinary homogenizing machine converted into a heating table?"
　　 "That's right." Xu Qiu responded:
　　 "Or you can close the glue secretly, do a good job of heat insulation, and then heat the inside to keep the temperature constant."
　　 "Well, there are two kinds of things you said. Relatively speaking, the former is more commonly used. However, I have never used the two, I just heard of them." Wei Xingsi thought for a few seconds and continued:
　　 "Let me make a call and ask."
　　 After speaking, he took out his cell phone and flipped up and down in the address book.
　　 stopped for a while before a name, he shook his head slightly, and continued to flip down.
　　 Finally, he stayed at Gong Yuanjiang's name and pressed the dial key.
　　 He didn't use the speakerphone, and the two were far apart, so Xu Qiu could only hear Teacher Wei's voice.
　　 "Hey, Yuan Jiang, it's me, Wei Xingsi."
　　 "How's it going, it's not going well recently."
　　 "I, I have just returned to China and I am very busy. When I have time, I must go there."
　　 "Yes, everything is difficult at the beginning."
　　 "By the way, I have a student who has a little problem doing experiments and wants to buy a glue spreader with heating function. Do you have any channels? We want to get one.
　　 "Yes, that's great."
　　 "Yes, it's the kind with its own heating station."
　　 "Okay, okay, when you send me the contact information, I let my students contact your students, thank you so much."
　　 "Okay, keep in touch when you have time, goodbye."
　　 The phone hangs up.
　　 The water just boiled has already boiled. Wei Xingsi opened a packet of tea leaves, first flushed the teapot with boiling water, then put the tea leaves, pour the boiling water, pour out the first bubble, and start the second bubble.
　　 "It's done," Wei Xingsi laughed:
　　 "Gong Yuanjiang is a friend I met in the early years. He has been doing organic work in China for more than ten years.
Now you are a big man in the field of organic photovoltaics, you should usually read a lot of his articles~EbookFREE.me~ Xu Qiu nodded. The name of Gong Yuanjiang, Xu Qiu, is no stranger. He is a leader in the field of organic photovoltaics in China. For one, you can often see articles about him as the corresponding author in top journals such as AM.
　　"He said that there is no manufacturer of this kind of heating and homogenizing machines in China, and they have to be imported from abroad.
　　Their group is relatively large, and there will be more of this equipment, so I ‘lent’ the spare one to us, wait for you... "
　　 At this time, Teacher Wei's cell phone lit up, it was a text message.
　　 He glanced, and continued:
　　 "This is the phone number of a student in Gong Yuanjiang's group. I will send it to you. You can contact him and tell him our address. We need to send it by mail, and we will pay the courier fee."
　　 "Have you received the text message?"
"received."
　　 "Any other things?"
　　 "No more."
　　 "Okay, then go ahead and contact me if you have any questions."
　　……
　　 Leaving from Teacher Wei's office, Xu Qiu couldn't help feeling, he was busy for a long time, and Teacher Wei resolved it with just a call.
　　 If I knew earlier, I might as well take a mouth and go straight to him.
　　 Xu Qiu also realized the importance of the team again.
　　 Teacher Wei has been in the field of scientific research for more than 20 years. Although he mainly develops abroad, he still has certain resources and contacts in China, and he will make more use of it in the future.
　　 After all, as the leader of the entire scientific research team, Xu Qiu has made achievements. For him, it is also a win-win situation.
　　 As for Gong Yuanjiang and Teacher Wei PY an instrument, what is the nature of this and what process should be followed.
　　 Xu Qiu didn't know, anyway, he just did his own experiment.
