Foam with all water. The sound insulation effect of the filling is particularly good. Since the combined polyether uses water as the foaming agent, the water as the foaming agent is also green and environmentally friendly.

We may be very surprised to hear honeycomb, but in fact, this is also a very common material in security doors. It has the advantage that it is very cheap, very lightweight, and very well insulated. This is completely different from the paper shell door we imagined.
The sound insulation effect of this filling is also very good, not only safe and environmentally friendly, but also the security door produced by the all-water foam material has the characteristics of high temperature resistance, which can withstand high temperatures of more than 200 degrees. This security door has a very long service life and is suitable for use in places where fire is susceptible.

I don't think I have any outstanding strengths, and I think the most important thing I learned in my five years at university was that I learned some ways to analyze problems and look at things. I studied architectural design, and in design, especially when designing large and complex public buildings, it often involves the simplification of some complex problems, and often needs to be repeatedly verified from the whole to the part, from the part to the whole, so as to be able to grasp the main contradiction of the problem and find a suitable solution. I think it's very beneficial to me. >>>More
The better ones are filled with polyurethane foam, some are made of rock wool, and some are made of straw and cardboard.
