Control Of Pre-Cured Product Moisture For Formaldehyde-Free Fiberglass Products
US Patent:
7435444, Oct 14, 2008
Filed:
Jul 23, 2004
Appl. No.:
10/897804
Inventors:
Charles John Freeman - Littleton CO, US
Mark William Charbonneau - Littleton CO, US
Richard Thomas Packard - Elbert CO, US
Mark William Charbonneau - Littleton CO, US
Richard Thomas Packard - Elbert CO, US
Assignee:
Johns Manville - Denver CO
International Classification:
B05D 3/00
US Classification:
427 8, 4273898
Abstract:
A system for controlling the residual moisture in pre-cured binder coated glass fibers. The moisture of the binder coated glass fibers is measured after the process water is extracted in a collection box. Based on the level of moisture found in the coated glass fibers, adjustments are made to the process upstream of the moisture measurements. The adjustments include, but are not limited to, adjusting the amount of water used to make the binder composition; adjusting the amount of heat applied to the binder composition as it is applied to the glass fibers and adjusting the vacuum conditions used to extract the process water from the binder coated glass fibers. Control of the residual moisture in the precured binder coated glass fibers helps ensure proper curing of the binder during the subsequent curing step.
Infrared Methods Of Measuring The Extent Of Cure Of A Binder In Fibrous Products
US Patent:
7435600, Oct 14, 2008
Filed:
Jun 23, 2004
Appl. No.:
10/874671
Inventors:
Richard Thomas Packard - Elbert CO, US
Assignee:
Johns Manville - Denver CO
International Classification:
G01N 33/44
US Classification:
436 85, 436128, 436129, 436171
Abstract:
A method of measuring the extent of cure of a binder in a fibrous product is provided. The method comprises (a) providing a sample of a fibrous product, the fibrous product comprising fibers and a binder, (b) subjecting the sample to infrared spectroscopy to generate a spectral analysis, and (c) determining a binder cure ratio of the binder in the sample using the spectral analysis. The binder has carboxylic acid groups and alcohol groups that crosslink to form ester groups as the binder cures, and the binder cure ratio comprises a ratio between infrared absorption corresponding to a bond of the carboxylic acid groups in the binder and infrared absorption corresponding to a bond of the ester groups in the binder.

US Classification:
700198, 700109, 700204, 700208, 702173, 264 404
Abstract:
A method for determining the extent of cure of binder in a product comprising heating a sample of the product to vaporize free moisture in the sample and expel vaporized free moisture from the sample, measuring cure moisture content of the product, measuring binder content of the product, calculating a product ratio of cure moisture content to binder content, and comparing the product ratio of cure moisture content to binder content to a predetermined desirable ratio of cure moisture content to binder content.
