摘要:
Gypsum panels, panel cores, and methods for the manufacture thereof are provided herein. A gypsum panel core includes gypsum and fiberglass, the fiberglass being present in the core in an amount of from about 1 lb/msf to about 6 lb/msf. The core has a thickness of about 1/2 inch, a weight of from about 1400 lb/msf to about 1750 lb/msf, and an ASTM E-119 wood stud fire test rating of at least 30 minutes.

Gypsum based compositions, processes for making same, and articles made therefrom. In one example, the gypsum based composition can include about 1.5 wt % to about 3 wt % of a starch, about 11 wt % to about 14 wt % of a paper, about 0.7 wt % to about 2.3 wt % of vermiculite, about 1.3 wt % to about 3 wt % of a plurality of reinforcing fibers, about 7 wt % to about 10 wt % of a binding agent, about 2 wt % to about 4 wt % of perlite, and about 65 wt % to about 75 wt % of a calcium sulfate, where all weight percent values are based on a combined weight of the starch, paper, vermiculite, plurality of reinforcing fibers, binding agent, perlite, and calcium sulfate.
摘要:
A method and device for producing lightweight panels with a core of gypsum or of cement and gypsum, with pores for decreasing volumetric weight, and with a covering made of cardboard or of a sheet of glass fibers. The production line does not change except for the addition of a device which forms closed hollow cavities within a suspension in an area where an upper sheet covers the suspension. Air pressure which is fed into the formed cavities is slightly higher than the hydraulic pressure of the suspension, so as to prevent the gaps being filled by the suspension. The layers are less thick, and the type and dimensions of the cavities and the thickness of the walls are varied depending on the desired qualities of the panels.

摘要:
A method for identifying the source of vermiculite insulation in situ using a portable spectrometer with a light-emitting contact probe and a personal computer. Identification is accomplished using NIR reflectance spectroscopy and absorption band depth ratios to differentiate between vermiculite sources and to test for the presence of amphibole, talc, or serpentine contaminants in vermiculite insulation.
摘要:
The present invention relates to a pearl pigment obtained by coating the surface of a flaky powder with a colored metal or a colored metal oxide and further coating the surface of the above colored metal- or colored metal oxide-coated flaky powder with a colorless metal or a colorless metal oxide, wherein when the pearl pigment is applied onto the surface of black artificial leather in an average amount of 0.05 mg/cm2 and the intensity of light reflected from the pearl pigment is measured using illuminant C at a 2° viewing angle with a spectrophotometric colorimeter which is provided with a sheet polarizer S on the light incident side and a sheet polarizer P on the light receiving side, the powder reflection light which is incident to the pearl pigment as a measurement sample at an angle of 45° to the direction normal to the surface of the sample and is received in the direction normal to the surface of the sample has absolute values a* and b* of 10 or less, and make-up cosmetics containing the pearl pigment.
