Lexan is a registered trademark for SABIC Innovative Plastics' (formerly General Electric Plastics) brand of polycarbonate resin thermoplastic. Polycarbonate polymer is produced by reacting bisphenol A with carbonyl dichloride, also known as phosgene. Lexan is the brand name for polycarbonate sheet and resin in a wide range of grades. Applications are mainly in three domains–building (glazing and domes), industry (machine protection and fabricated parts) and communication and signage. Common usages include space and sports helmets, clear high performance windshields and aircraft canopies, and bullet resistant windows.Fyi - lexan is a Tm trade name for polycarbonate. Plexiglas is the same for acrylic.
Like "pyrex" means "borosilicate glass" - but only Corning can call it Pyrex, Kimble has to call it K-33. Neither plastic has any plasticizer added at manufacture, but some of the catalyst that makes the monomer polymerize might be left, along with whatever mold release agent. Clean before using!
No matter what - I'd ditch the first few batches if that worried me. The nose is pretty good at detecting that kind of thing.
Is that why NASA set up camp there ? :rotflmbo:RB2,
Here in Florida, we do not have the luxury of gravity
Can you explain this term ?I can save a grand if I do the midnight express deal,
Wow. Now you have informed me of something about which I did not know. Thinking about it some more, it makes perfect sense that rainwater or distilled water would perhaps dissolve certain substances and carry them out of the body.My understanding is that rainwater is not ideal for us to drink as it is 'immature' and seeking metal salts that it will strip from the salts in our body.
Distilled water is actually dangerous for us to drink except for short term detox.
The best water is water that has completed its cycle through the ground, picked up the salts it seeks and breaks the surface as a spring. The higher the spring breaks, the better it is for us apparently.
Water from a high mountain spring sounds good and is good for this reason.
Agree that cancer is often triggered by worry /stress, plenty of evidence for this and plenty of evidence for healing cancer with the opposite, with positive thought.
Stopped using big pharma years ago and the more I read the more convinced I become that we fix ourselves, although massive doses of radiation and very high g forces remain outside this approach.
Now researchers from the University of Texas at Austin and the University of Marburg in Germany have developed a “water chip” that creates a small electrical field that separates salt from seawater. The technology, which is still under development and works at the nano scale, uses so little energy it can run off a store-bought battery!
The researchers apply a 3.0 volt electrical charge to the plastic water chip, which has a microchannel with two branches. By creating an “ion depletion zone” with an embedded electrode that neutralizes chloride ions, they are able to redirect the salts in the water down one channel, while the fresh water goes down another.
“Like a troll at the foot of the bridge, the ion depletion zone prevents salt from passing through, resulting in the production of freshwater,” the team wrote in a recent press release.
Less energy-intensive than current desalination plants, the water chip doesn’t rely on a membrane, and can be made portable so that just about anybody living near the sea can purify their own water at home.
Currently the technology purifies just one nanoliter at a time and only has a 25% efficiency rate, but the team is confident that their proof of concept can be first improved and then scaled up.
