초록 ▼

An ultra-fine powder formed from a naturally occurring mineral or rock material and having a controlled or “engineered” particle size distribution (PSD) to match the infrared spectra with a maximum particle size in the range of 14-17 microns measured as either D99, or preferably D95, and a minimum particle size D5 in the range of 4-7 microns. Preferably the maximum particle size is about 15 microns, the minimum particle size is about 5 microns and the D50 particle size is about 8-10 microns with the moisture content of the particle size “engineered” powder being less than about 0.20 percent by weight and preferably about 0.05 to 0.08 percent by weight of the powder. This specially “engineered” ultra-fine powder is used to reduce the thermicity of thermal film to a value less than about 20%.

대표청구항 ▼

1. A method of producing an ultra-fine powder, said powder having a targeted maximum particle size D95 and a targeted minimum particle size D5 with a particle size distribution of D5 to D95 of less than 12 microns, said method comprises: (a) providing a ground feedstock formed from a naturally occurring mineral or rock material having a reflective index of about 1.4 to 1.6;(b) grinding said feedstock in a mill;(c) classifying said mill ground feedstock with a first classifier to produce an intermediate powder, said intermediate powder having a targeted D95 maximum particle size with a value, which value is in the range of 14-17 microns;(d) classifying said intermediate powder through a second classifier to remove all particles less than a targeted particle size with a value, which value is in the range of 4-7 microns to produce said ultra-fine powder having a targeted D5 minimum particle size with a selected value in the range 4-7 microns. 2. The method as defined in claim 1 wherein said feedstock is a material selected from the class comprising silica (including ground natural and diatomaceous), cristobalite, feldspar, quartz, nepheline syenite, kaolin, talc, attapulgite, pyrophylite and tridymite. 3. The method as defined in claim 1 wherein said targeted maximum particle size D95 of said ultra-fine powder is 15 microns. 4. The method as defined in claim 3 wherein said targeted minimum particle size D5 of said ultra-fine powder is 5 microns. 5. The method as defined in claim 4 wherein said feedstock in a material selected from the class comprising nepheline syenite, feldspar, silica, quartz, cristobalite and tidymite. 6. The method as defined in claim 1 wherein said first classifier is in said mill. 7. A method of producing an ultra-fine powder, said powder having a targeted maximum particle size D95 and a targeted minimum particle size D5 with a particle size distribution of D5 to D95 less than 12 microns, said method comprises: (a) providing a ground feedstock formed from a naturally occurring mineral or rock material having a Mohs hardness of at least 5;(b) grinding said feedstock in a mill;(c) classifying said mill ground feedstock with a first classifier to produce an intermediate powder, said intermediate powder having a targeted D95 maximum particle size with a value, which value is in the range of 14-17 microns;(d) classifying said intermediate powder through a second classifier to remove all particles less than a targeted particle size with a value, which value is in the range of 4-7 microns to produce said ultra-fine powder having a targeted D5 minimum particle size with a selected value in the range 4-7 microns. 8. The method as defined in claim 7 wherein said targeted maximum particle size D95 of said ultra-fine powder is 15 microns. 9. The method as defined in claim 8 wherein said targeted minimum particle size D5 of said ultra-fine powder is 5 microns. 10. The method as defined in claim 7 wherein said targeted minimum particle size D5 of said ultra-fine powder is 5 microns. 11. The method as defined in claim 7 wherein said first classifier is in said mill.
