Zhang Weicheng: I often see your enthusiastic participation, and the quality of your work is quite high – great job! ! Give it a push! !
This is really good:victory:
Hehehe, where’s Hua Lu? I don’t see him anywhere
Can it still work? Not even a shadow was seen! It seems there’s no construction!
Reply to 6# zhx023: Everything is ready; we have set off!
This is quite valuable and worth a look
Thank you to Zhang Weicheng; I am looking for information on polysilicon, as our company is planning to invest in the photovoltaic industry.
Experts: How many cubic meters of hydrogen are required to produce one ton of polysilicon?
This post is very useful; I hope the original poster will post more such practical posts. Thank you to the original poster for providing this! ! !
