Seeking help with a bachelor’s thesis on water-based polyurethanes
Thread Content
I’m currently working on a graduation project related to the production workshop for water-based polyurethanes. But since this is clearly an already industrialized product, I can’t find any information about it :(? The documents and patents from CNKI and Wanfang are all reviews and various modifications; industrial production processes are rarely discussed. Is there anyone who can give me some guidance? Where should I look to find the manufacturing processes for such mature industrial products?:Q
There seem to be many similar projects for undergraduate graduation theses; if the requirements aren’t too high, one can manage to get by with a shoddy effort.
The manufacturing processes for water-based polyurethanes are kept secret by each manufacturer, and there are slight differences among these processes; the procedures are relatively simple, so it’s sufficient to visit the relevant manufacturers to see them.
