Re: What's that black dust in monitors?

[DarkMatter]

25 years ago I got many of my parts from TV sets tossed onto the curb,
so I ahve handled lots of that "electric black dust". I have found it to
usually be a little greasy if you squeeze it and dig into it, although it
is perfectly dry if you touch it lightly.

Oils are non conductive molecules, and are airborne. Cigarette
smoke, cooking smoke... the list goes on. The surface could have
anything short of a conductive material on it. VERY SIMPLE.

Argghh....
to the eternal block-list I hereby consign you all,
"Dark Matter", "Rod Speed" and "Phil Allison"

The only thing more retarded than the stupid Rod Speed poster, is the
stupid twit that thinks that his filter edit announcements have some
meaning or purpose. You be lame, boy. You be that retard.

 

[DarkMatter]

You mean you don't think it's amusing watching three
fools spending hours arguing about... dust?

Mike Harding

You're a fucking retard. Rod Speed is hopelessly arguing. The
others seem to have a grasp on reality. You obviously do not, because
you don't even know that you are a fool for calling others fools.

 

[DarkMatter]

It's a mote point.

Rob

It's a mote in your eye, you fucking clueless retard.

The word is MOOT, dumbshit.

 

[DarkMatter]

Maybe no one actually cares what
some gutless fuckwit chooses to read ?

Block lists do actually work if you dont
announce what's in them, fuckwit.

But then you wouldnt be able to posture, would you ?

And such a poor posture it is.

 

[DarkMatter]

But I have seen it in homes without combustion devices. Maybe it is
possible to get such black dust from neighbors or others upwind, and where
I am I certainly think the atmosphere has some soot from diesel-fueled
trucks and buses!

When I was a kid, I could climb a phone pole in five seconds flat.
Up the guy wire.

OI was in TJ, Mexico a few years ago, and jumped up to grab one of
those guy lines, and the damned thing had a half inch of the blackest,
wettest (oil and grease), nastiest shit on the planet on it. That
place is lame, and full of cooking smoke from the street vendors.

Case closed. Moist particulate turns dry brown dust black. Pretty
simple shit.

In my TV-trashpicking experience, the metal is not as much a target.

In the high field area around the HV components, including the
flyback xformer, the fields are so high that the dust in the field can
settle on any surface the field is impressed on. Including nearby
metal chassis parts. Just not as prevalent.

 

[DarkMatter]

What about me ????

I asked the original question and I still don't know !!!!!

You should have been able to glean from the posts the fact that it
is a dust accumulation that is influenced by the high corona field
present on anode supplies, and the CRTs they attach to.

Learn how not to top post.

A Japanese would at least have the decency to disembowel itself.

Dont make a mess of the carpet.

You're an idiot. At best.

Mine are mostly pretty transparent, very light colored.

I don't know. I know that a dusty surface ribbed
with oily hands moistens and blackens the dust.

When I score lines on a new, plastic project box for cuts to
be made, I can rub the scores with my fingers, and the dirt
on my hands alone will turn the scores to a black line.

Dark line, anyway. Not the jet black soot
you get adjacent to the FBT in a monitor tho.

Clothing colors darken upon getting moist or wet.
Yes.

I am certain that dust will also follow this trend.

Yes, but it doesnt end up jet black like
the soot adjacent to the FBT in a monitor.

And that jet black soot adjacent to the
FBT in a monitor isnt moist or wet anyway.

So, even dust that is not initially black could easily turn that way
if ALSO moisture particles are being drawn to the surface.

Fraid not. And while dust certainly gets darker when
moist or wet, it lightens in color when it drys out again.
That jet black soot adjacent to the FBT in a monitor isnt
wet or moist at all, and is still jet black when completely
dry when the monitor is quite warm when used in summer.

Neons hove nowhere near the corona levels found inside
consumer monitors that have "open air" design HV components.

The military and space organizations have known about
this, and have fully potted HV sources for decades.

Yes, but thats so you dont end up with moist dusty arc paths.

Nothing to do with where the jet black soot
adjacent to the FBT in a monitor is coming from.

And FBTs are epoxy coated themselves.

The only remaining open air stuff is that which
is in transmitters, and they are fully caged.

The fact remains that it is indeed an accumulation,

Just claiming its a fact doesnt make it a fact.

and NOT some kind of emission,

Just proclaiming that cuts no mustard.

Pity what was clearly being discussed
there was 'positively charged surfaces'

Including nearby metal chassis parts. Just not as prevalent.

In fact there is MORE soot on the metal, just because its closer
to the FBT than the inside surface of the case adjacent is.

That was one of those funky plays on words, Joyce.

Learn to answer HIS post when you want to refer to HIS words,
dipshit.

Yes, it can.

Not with water.

Fraid not.

Afraid so, dipshit.

Again, the "moisture" we refer to here is NOT water. Try to keep
up.

You keep grasping at straws. Face it, dipshit... FBTs do NOT give
off any emissions other than electrical or magnetic ones, and the dust
inside a monitor is an accumulation that is caused directly by the
e-fields present in proximity to said accumulations.

Yes, but thats so you dont end up with moist dusty arc paths.

DOH! What have we been discussing, dweeb boy?

Nothing to do with where the jet black soot
adjacent to the FBT in a monitor is coming from.

It is an accumulation FROM the air, dingbat. Nothing more.

And FBTs are epoxy coated themselves.



Just claiming its a fact doesnt make it a fact.

No, but decades of experience and several years of HV experience
DOES.

Just proclaiming that cuts no mustard.

RETARD. FBTs do NOT give of black soot. How can you be soooo
fucking retarded, and claim to have been trained?

Cutting mustard is something that will forever elude a retard such
as yourself.

 

[DarkMatter]

Pity what was clearly being discussed

Pity? Would you please grow the **** up, boy?

A grounded metal chassis has no charge on it. Doh!

If it is in proximity to a high strength field, however, it can
accumulate dust, right along with the charged surfaces. And nobody
ever said what polarity they had, except for your lame ass.

In fact there is MORE soot on the metal, just because its closer
to the FBT than the inside surface of the case adjacent is.

The word for today is FIELD. Learn it. Try to get out of the pit
you are in, boy.

I sure see many thousands of diesel trucks, enough of which spew soot
into the air.

And what about tire rubber and carbon? That rubber goes somewhere...

You dont get much black soot inside houses from those.


Nope. And bugger all of that ends up inside houses anyway.


We dont see much of that anymore, oil fueled.

Very common in and near Philadelphia!

Doesnt mean you import much 'invisible soot'


You claimed you get it everywhere, not just in the TV and monitor.

I dont buy that.


Yes, but that aint necessarily the jet black we are discussing.

Most smog seen with citys is actually brown, not jet black.

The brown color is mainly from nitrogen dioxide, which is usually the
3rd worst pollutant in the Philadelphia area in terms of health even
though it colors the air more than soot and ozone do.

I've seen this black 'stuff' on monitors in the Pacific islands - there sure
as hell weren't enough diesel vehicles (or tyres, for that matter!) to do
this.

No such animal.


Nope.
Nope. No such animal.

Tried web searching... Looks like you're right on that one, and cobwebs
made solely of dust was something that I heard incorrectly before.
My cobwebs are definitely at least part dust and are usually very dark
in color, much darker than most of the dust in my home.

I just tried adding some water to some ordinary dust and rubbing it
with my fingers. It got darker, but not jet black like the dust in TV
sets. I think some kinds of dust particles are more atracted to the high
voltage points in TV sets than other kinds are.
