What are the applications of sizing agents in fiberglass?
Lubrication protection function:
Wet lubrication: During the fiberglass pool kiln drawing process, the lubricant component in the impregnating agent can maintain a certain lubrication between the fiberglass precursor and the oiler and the clustering groove, reducing wear.
Dry lubrication: In the post-processing process, it can avoid uneven tension of the original fiber caused by excessive friction coefficient between the fiberglass original fiber and the textile machinery, which will cause flying fibers and difficulty in unwinding the original fiber.
Enhancement:
The film-forming agent bonding component in the sizing agent can bond the fiberglass monofilaments into a bundle of fiberglass raw yarns, ensure the integrity of the raw yarns, avoid stress concentration on one or several monofilaments, reduce broken or scattered yarns, and facilitate the decomposition of the raw yarn tube and the post-spinning processing of the fiberglass yarn.
The impregnation agent can also make the fiberglass reinforcement and the resin matrix have good interfacial compatibility and interfacial chemical bonding properties, thus achieving a reinforcing effect.
Give special properties:
The sizing agent can also give the fiber certain special properties, such as bundling, choppability, and dispersion, according to the different process requirements of the molded products. These properties are crucial to the subsequent processing and application of fiberglass.
Eliminate static electricity:
The antistatic agent component in the sizing agent can eliminate or weaken the static electricity on the fiber surface, ensuring the smooth progress of the production process.
