Whether the extruded plastic board ceiling is soundproof and harmful

There is a certain sound insulation effect, the harm is not a big problem, the main home ventilation is good, there is no problem, please rest assured.

Let's start with that. I sell extruded plastic panels.

About whether it can be soundproofed.

Then relatively speaking, you can say whether you have achieved your ideal effect.

and not play soundproofing.

The so-called ideal effect is.

You feel like it's soundproofing.

Then it acts as sound insulation.

There are also standards for noise.

The ordinary effect is still there.

That's all I can do.

Question 2.

Whether it is harmful.

The raw material of extruded plastic board is polystyrene.

So. It is a toxic substance in itself.

And there is. How far away is the extruded plastic board from the hot object?

For example, light bulbs. The explanation is as follows.

The temperature resistance of extruded plastic board is up to 78C degrees.

So. It is recommended not to place it close to the hot object.

Also, don't be greedy when buying extruded plastic boards.

The best price is 450 per cubic plate.

This way you will have a longer lifespan.

If the buy price is between 250 300.

It is still recommended that you use EPS

20 grams is more realistic.

The performance is already good with the 250 300 extruded board.

These are just some of the things I've learned from doing this business.

FYI.

It is sound insulation, and the raw material of the extruded board is polystyrene hex, so it itself is a toxic substance, so it is harmful.

Polystyrene foam is divided into two kinds of intumescent EPS and continuous extrusion type XPS, compared with EPS board, XPS board is the third generation of hard foam insulation material, from the process it overcomes the complicated production process of EPS board, with the superior performance that EPS board can not replace. It is made of polystyrene resin and other additives through the extrusion process to produce a continuous uniform surface layer and closed-cell honeycomb structure of the board, these honeycomb structure of the thick plate, there will be no voids at all, this closed-cell structure of the insulation material can have different pressures (150-500Kpa) and has the same low value of thermal conductivity (only and enduring excellent thermal insulation and compressive performance, compressive strength up to 220-500Kpa.

Of course, there will be some heavy metal elements in this, the sound insulation effect is still OK, there is a kind of mineral wool board, the project is mainly used for this, you can understand it, sound insulation, fire prevention, moisture-proof effect is very good.

The old process used freon or liquefied gas as a blowing agent. After the production is completed, these two gases will slowly emit out from the extruded plastic board, fluorine gas is a toxic gas, which can harm everyone's health, and the common disease is cataract. At present, most domestic manufacturers still use this backward process.

Some manufacturers have already started using CO2 (carbon dioxide) as a new blowing agent. CO2 itself does not burn and does not support combustion, so it is relatively safe to use CO2 in both the production process and the installation process of extruded plastic panels. Make our living space more environmentally friendly.

The harm of not catching fire is not too large, and once a fire occurs, it will be great.

In the case of not being heated and not combusting, the polymer generally does not automatically decompose, nor does it release toxic gases, and the volatilization of various additives is also minimal, and the main indoor fire is prone to occur, and the consequences are very serious, so I will tell you seriously.

The sound insulation effect is average.

It must be harmful.

I'm also looking at this issue, and I don't think so.
