Interesting article. Thank you!
However it speaks about coal which, contrary to charcoal, is not a pure carbon. I might be wrong, but these sentences of the article seemingly suggest that the oxidation process doesn't involve C but rather other substances:
"What was immediately apparent from...
A) You are right that in the long term there will be fires if one just dumps a lot of charcoal above the ground. But I was thinking about possible useful ways of utilization of charcoal instead of just burying it. E.g. this patent suggests to use carbon as hydroponic growing medium. This way you...
Thank you!
1. Let's assume we are in a hot climate. 45 degrees Celsius 24/7... Can we still assume that there will be no oxidation of charcoal for all practical purposes?
2. Is humidity a factor here? Or even more - if we put the charcoal regularly into direct contact with water - will this...
I have specifically emphasized that no fire is involved. Only air and rain water. One of the answers I got elsewhere:
"The spontaneous oxidation of charcoal by air at room temperature happens spontaneously. But it is so slow that it can be forgotten. The half-life of the reaction iis much much...
Wikipedia — Carbon sequestration claims that burying charcoal into the soil offsets CO2 and thus reduces the greenhouse effect:
Is it a must to cover charcoal/biochar with the soil to prevent the air and rain water exposure to avoid oxidation, i.e. offset carbon dioxide? Would it otherwise...
Thank you! This is very wise thing to do and I actually wanted to go this way. Just needed to get some general info/direction about the proper material (material groups) to be able to start the conversations with those guys involved in injection molding. That's why I'm here :)
Thank you, and to all the many forum member who try to help. I'll try to follow your advice and be more specific regarding requirements:
1. capable to retain form/shape under pressure (that's what I meant by hard/rigid).
2. non toxic (as close to "food grade" as possible)
3. low chemical...
Can ceramics (and the others - silicate minerals, zeolites, silicon carbide) be used in injection molding? I thought ceramics is more like glass which needs to be blown molded?
1. A good engineer can listen to a non-engineer and understand what he means even when the latter doesn't use precise, correct terminology. You see, you seem to understand what I mean. Quantitative information - comparable to PVC.
2. How will I know? I'll take it in my hands and see whether it...
I saw rubber-like silicones. Are there types of silicone that can be used in injection molding and once the process is finished - become as hard as, let's say, PVC? At the same time they should have all(/majority) of silicone's properties (citing Wikipedia):
- Low thermal conductivity
- Low...
Thank you for all the information. Is there such thing as glass injection molding (instead of blowing)? If yes, then probably both shapes can be mass produced by dividing them into two sub-shapes - the bottle and the bottom. Both could be produced with regular simple double-mold (even holes...
