Pasted and Unpasted Wallpaper Gross Calorific Values
Pasted and Unpasted Wallpaper Gross Calorific Values
(OP)
Hi guys,
I've been doing some research into building materials and their calorific values.
I came across the fact that the gross calorific value of unpasted wallpaper is higher than that of pasted wallpaper, which is strange considering the addition of an adhesive to the latter samples? I would have expected pasted wallpaper to have a higher gross calorific value.
Anyone know why this is?
Thanks in advance.

Paste potentially has two effects:
> Incorporated water, which would reduce the gross calorific value, since it takes heat to boil off the water
> General fire retarding effect from the solids within the paste

Why are you looking into the GCV anyway? I don't have any experience burning wallpaper, but I imagine it would be something you want to avoid.

Since some of these "papers" are actually vinyl, burning them would be a really bad idea.

2.) Calorific values for wallpaper seem about as pertinent as caloric values for a slice of pizza: you can find a published calorie value for a slice of pizza, but it is really going to depend on the particular slice. I would be curious about the source of the data on wallpaper. People have a tendency to publish values without knowing much about the source of the data.
