Abstract

The invention belongs to the technical field of quantitative test and analysis of glass fiber surface attachments, and particularly relates to a method and a device for simultaneously determining themoisture content and impregnating compound content in glass fibers. The method comprises the following steps: firstly, sequentially carrying out nuclear magnetic resonance analysis on glass fiber samples with known different water contents and impregnating compound contents, and respectively acquiring nuclear magnetic signals of the water contents and the impregnating compounds of the glass fibersamples; according to the collected nuclear magnetic signals, building relation curves between the glass fiber moisture and impregnating compound content and the nuclear magnetic signals respectively;and carrying out nuclear magnetic resonance analysis on a glass fiber sample to be detected, collecting a nuclear magnetic signal of the sample, and obtaining the water content and the impregnating compound content of the sample to be detected by utilizing the relation curve. By adopting the technical scheme provided by the invention, the contents of the moisture and the impregnating compound ofthe glass fiber sample can be simultaneously determined, the operation is convenient, the accuracy is high, the test time can be greatly saved, the glass fiber production process is convenient to control, and the product quality and the stability between batches are improved.

Description

technical field [0001] The invention belongs to the technical field of quantitative testing and analysis of glass fiber surface attachments, and in particular relates to a method and a device for simultaneously measuring the contents of moisture and wetting agent in glass fibers. Background technique [0002] Sizing agent is an indispensable consumable in the process of glass fiber processing and production. Its main functions include lubricating protection, bonding and clustering, preventing the accumulation of net charges on the surface of glass fibers, and providing glass fibers with the characteristics required for further processing and application (such as chopping, banding, dispersibility, etc.) and to make the glass fiber have good compatibility with the substrate and interfacial chemical bonding or chemical adsorption. Currently, the sizing agent is mainly water-based. Therefore, the glass fiber The content of moisture and sizing agent in the fiber is the most criti...
