Gå in på länken för att se alla bilder. detta svarade alla mina frågar om färg argumentet, chipsen dom har antänds på låga temperaturer av 430C något det inte ska göra om det är färg, i NIST egna tester är färg stabilt under 800C. chipsen dom har har inte dom rätta ingredienserna i sig som färg ska ha. sedan har vi ju även det som faller ut från tornet strax innan kollapsen som redan är bevisat att det inte kan vara aluminum.

It has been suggested, that the red/grey chips discovered in the dust from the WTC collapse catastrophe1 could originate from rust-inhibiting paint (primer paint) applied to the steel beams in the towers. This letter compares the elemental composition and the thermal stability of the two materials based on the description of the protective paint in the NIST report and observations on the red/grey chips.

CHEMICAL COMPOSITION OF THE PRIMER PAINT

The primer paint applied to the steel beams of WTC is described and characterized in NIST NCSTAR 1-3C appendix D2.

The primer paint is red/orange and was originally applied in order to protect the steel against corrosion.

Examples of typical beams are shown in Figure 1 and Figure 2.

from NCSTAR 1-3C appendix D2.

Figure 2

The color is due to the pigments in the paint. Iron oxide is red and zinc chromate (”zinc yellow”) is – well – bright lemon yellow (Figure 3).

Since the ”vehicle” is obviously fluid, the values for the ingredients in it must refer to the paint before application in w/w percentage.

Even though the composition of the Tnemec pigment is proprietary, the content of this component can be obtained from the Material Safety Data Sheet, from which the pertinent information is reproduced in Figure 4:

Figure 4
Extract from Material Safety Data Sheet for Tnemec pigment3.

Talc is magnesium silicate hydroxide, Mg3Si4O10(OH)2.

The content of calcium silicates and aluminates is inexact, and that the relative contribution of aluminates is not specified.

Since the Tnemec pigment contributed 33.7 % to the wet primer paint, the content of these two ingredients and the solvent in the wet primer paint was:

Talc Mg3Si4O10(OH)2 7 – 10 %
Calcium silicates or aluminates 2 – 3.3 %
Mineral spirits: 7.6 %

After application, the paint was baked at 120 °C. In this process all volatile ingredients evaporate. Thinners (Figure 3) and mineral spirits (from the Tnemec pigment) amount to (32.3 + 7.6) 40 %. If we subtract these from the w/w composition percentages given above, we get a rough estimate of the composition of the hardened paint.

That is, by dividing by 0.6 we get the following values for the decisive ingredients of the hardened paint (dismissing the trivial elements iron, silicon, carbon and oxygen):

Component Composition in wet paint Composition in dry paint
Zinc chromate (ZnCrO4) 20.3 % 34 %
Talc (Mg3Si4O10(OH)2) 7 – 10 % 12 – 17 %
Calcium silicates or aluminates 2 – 3.3 % 3.3 – 5.5 %

COMPARISON WITH THE COMPOSITION OF THE RED/GRAY CHIPS

The elemental composition of the red/gray chips was obtained by means of X-ray Energy Dispersive Spectroscopy (XEDS) in the SEM mode1. Before measurement, the chips were broken (with one exception to be discussed below) in order to secure a fresh uncontaminated surface from which the SEM XEDS was obtained. NONE of these SEM XEDS spectra, taken from four independently collected samples, showed signals from either zinc, chromium or magnesium in intensities significantly above the baseline noise. See the right panel of Figure 5 below in which the intensity scale is expanded. Strong signals from these three elements could be expected from the primer paint according to Table 1.

Figure 7 in Harrit et al.1, showing the four different samples investigated.

The same spectrum as in frame (a) with intensity (vertical) and horizontal scales expanded. Minute signals in level with the noise are observed from sulfur, calcium, chromium and strontium.

Figure 5
SEM XEDS (beam energy 20 keV) spectra from fresh surfaces of red phase of red/gray chips.

In one experiment the chips were to be soaked in methyl ethyl ketone (MEK) and could not – for good reasons – be broken before. The resulting XEDS of this chip (Figure 6, below) displays tiny blips indicating the presence of chromium and zinc. They disappeared after the chips had been soaked/rinsed with the organic solvent. Therefore, they are believed to derive from surface contamination, which very well could have been from the primer paint(!).

Figure 6

SEM XEDS (beam energy 20 keV) from unbroken chip before soaking in MEK. The calcium and sulfur are likely to originate from contamination with wallboard material (gypsum, calcium sulfate). The signals from zinc and chromium could be from surface contamination with primer paint.

Magnesium was never observed, which is another element characteristic of the primer paint (Table 1).

It should also be noticed, that the only possible source of aluminum in the primer paint is the rather vague reference to ”calcium silicates or aluminates” in 3.3 – 5.5 % presence. Without attempting any quantitative estimates (not a trivial matter in XEDS), it is still very hard to accept this component as the source of the bright-and-clear signals for aluminum from the red phase of the red/gray chips.

THERMAL STABILITY OF PRIMER PAINT

NIST was interested in the thermal response of the primer paint since examination of the condition on the recovered steel beams could be indicative of the temperatures they had been exposed to.

NIST carried out temperature studies on selected beams and made the following observations2. The paint is unaffected to temperatures up to 250 °C (Figure 7a). At higher temperatures the paint starts showing ”mud-cracks” as they can be seen in Figure 7b (left). This fracture is due to the different expansion coefficients of the steel and the paint. It gets worse at 650 °C (Figure 7, right) at which temperature black ”scales” (layers) begin to form between the paint and the steel (Figure 8). NIST took the samples beyond 800 °C at which temperature the scale formation and peeling off of the paint from the steel was prevailing. One may hypothesize that formation of the black scales is due to charring of the organic binder.

Notice, that the primer paint – being basically a ceramic material – is chemically stable at temperatures up to 800 °C.

COMPARISON WITH THERMAL STABILITY OF RED/GRAY CHIPS

In contrast to the primer paint, the red/gray chips react violently, igniting in the neighbourhood of 430 °C. The reaction must produce temperatures no less than ca. 1500 °C, since the residues of molten iron are clearly seen in the optical microscope (Figure 9).

CONCLUSION

The properties of the primer paint and the red/gray chips are inconsistent.

The red/gray chips cannot be the primer paint as it is characterized by NIST.

Debunkers, om det är färg, varför fick dom inga starka signaler från zink och krom? och varför fattas magnesium?. hur förklarar ni formationen av järn rika klot av mikro storlek UNDER antändningen. formationen av dessa järn rika klot innebär extremt höga temperaturer. dom utsatte aldrig chipsen för högre temperaturer än 700C, det krävs över 1200C för att smälta järn. Järn-oxid kornen är 100 nm vilket passar kraven för nano-thermite. dom undersökte även chipsen noggrant innan antändningarna och där fanns inga järn klot då.

Kan ni komma med ett enda exempel på något material, som hade ragerat som deras chips i deras experiment?. Kan ni förklara ursprunget av deras aluminium plattor och järn oxid nanopartiklar och hur dom blev mixade på ett silicium lager i relativt rätta proportioner.

Det röda lagret av deras röda/gråa chips innehåller, aluminum, järn och syre komponenter som är mixade på en skala av ca 100nm som passar kraven för nano-thermite. en jämförelse mellan deras tester av chipsen från WTC med ett annat test av en känd super-thermite visar att båda antänds under 560C, alltså är materialet i deras chips från WTC finare då det antänds redan vid 430C

Super-thermite är komponerat av aluminum och järn oxid med åtminstone en komponent som är ca 100 nm eller mindre, ofta tillsammans med silicium och carbon, detta är precis vad dom hittade i deras chips. en rapport ifrån april 2000 visar att teknologin för att göra den här typen av super thermite fanns innan 2001:

“Nanostructured composites are multicomponent
materials in which at least one of the component
phases has one or more dimensions
(length, width, or thickness) in the nanometer
size range, defined as 1 to 100 nm. Energetic
nanocomposites are a class of material that have
both a fuel and oxidizer component intimately
mixed and where at least one of the component
phases meets the size definition. A sol-gel derived
pyrotechnic is an example of an energetic
nanocomposite, in which metal-oxide nanoparticles
react with metals or other fuels in very
exothermic reactions. The fuel resides within
the pores of the solid matrix while the oxidizer
comprises at least a portion of the skeletal ma-trix. As an example, energetic nanocomposites of FexOy and metallic aluminum are easily synthesized. The compositions are stable, safe and can be readily ignited”

“Reaction rates between nanosize aluminum
and metal oxides can be significantly greater
than those observed with traditional micron-size
thermite powders. Reactions occurring between
metal and metal oxide powders are accompanied
by the generation of high temperatures
(>3000 K). Super-thermites, formed by mixing
of aluminum and metal oxide nanopowders result
in energy release rate by two orders of
magnitude higher than similar mixtures consisting
of micron size reactants”
