Description
Wärmeschutzmittel und Verfahren zu seiner Herstellung
Zur Ermittlung der Infrarotreflexion kann z. B. das Fotometer nach Prof. Dr. Mecke Anwendung finden, bei dem das zu prüfende Flächengebilde mit Hilfe einer Ulbrichtschen Kugel diffus, beleuchtet wird. Die von der Probe reflektierte Strahlung wird auf eine Fotozelle gelenkt unter Zwischenschaltung eines Filters, das nur den infraroten Anteil das Lichtes durchläßt. Der Fotostrom der Fotozelle ist ein Maß für die Reflexionsfähigkeit der Probe für infrarotes Licht. Durch Auswahl der Filter kann man das Reflexionsvermögen der Probe in jedem interessierenden Wellenlängenbereich des Infrarotlichtes messen.To determine the infrared reflection can, for. B. the photometer after Prof. Dr. Find Mecke application in which the fabric to be tested with the help an integrating sphere diffuse, is illuminated. The one reflected from the sample Radiation is directed onto a photocell with the interposition of a filter, that only lets through the infrared part of the light. The photocurrent of the photocell is a measure of the sample's reflectivity for infrared light. By choice The filter can measure the reflectivity of the sample in any wavelength range of interest measure the infrared light.
Zur Messung des erzielbaren Wärmeschutzes kann folgende Meßanordnung dienen: Zwei oder mehrere gleichartige Hohlkörper, die gegen Wärmeaustausch mit der Umgebung durch Isolierung geschützt sind, werden mit ihrer offenen Seite in gleichem Abstand vor einer Strahlungsquelle aufgestellt. Sie werden mit einem Thermometer versehen, das die Messung der Temperatur des Hohlraumes gestattet, und an ihrer der Lichtquelle zugekehrten Vorderseite mit dem flächenhaften, flexiblen Gebilde verschlossen, das den Wärmeschutz herbeiführen soll. Beispielsweise wurden drei zylindrische Pappdosen verwendet, deren Öffnungen mit drei verschiedenen Fölien aus Weich-PVC verschlossen und dem Licht einer starken Glühlampe zugekehrt waren. Die drei PVC-Folien unterschieden sich wie folgt: a) Weiße Folie, stark mit Titandioxyd pigmentiert; b) desgleichen, die der Strahlungsquelle zugekehrte Seite bestrichen mit einer Druckfarbe, die mit Ruß pigmentiert war; c) wie b), jedoch die Druckfarbe pigmentiert mit einem Gemisch aus den obengenannten infrarotreflektierenden Pigmenten, deren Farbton im sichtbaren Licht so dunkel erschien wie die Folie b).The following measuring arrangement can be used to measure the achievable thermal protection serve: Two or more identical hollow bodies that prevent heat exchange with the surroundings are protected by insulation, with their open side in placed at the same distance in front of a radiation source. You will be using a thermometer provided, which allows the measurement of the temperature of the cavity, and on their the front facing the light source with the flat, flexible structure closed, which should bring about the thermal protection. For example, three were Cylindrical cardboard boxes are used, the openings of which are covered with three different foils made of soft PVC and turned towards the light of a strong incandescent lamp. The three PVC films differed as follows: a) White film, heavily with titanium dioxide pigmented; b) the same, coated the side facing the radiation source with an ink pigmented with carbon black; c) as b), but the printing color pigmented with a mixture of the above infrared reflecting pigments, whose hue appeared as dark in visible light as film b).
Anfangs befanden sich alle drei Pappdosen mit den vorgespannten Folien
auf der gleichen Temperatur (etwa 20°C). Im Verlauf von einigen Minuten bildeten
sich jedoch im Inneren der drei Pappdosen erhebliche Temperaturunterschiede aus.
Die Temperaturerhöhungen in den einzelnen Dosen und die Differenz zwischen den Temperaturren
der einzelnen Dosen sind in der folgenden Tabelle dargelegt (in Grad Celsius)
