Example Embodiment
[0044] The present invention has no special restrictions on the preparation method of the glass fiber, and the preparation can be carried out according to the tank kiln method well known to those skilled in the art.
[0045] Calculate the required raw material addition ratio according to the actual glass formula; according to this ratio, the various raw materials are quantitatively transported to the mixing bin, fully mixed uniformly, and qualified batch materials are obtained; the batch materials are transported to the kiln head bin of the tank kiln. The feeder is delivered to the kiln at a uniform speed; the batch materials are heated, melted, clarified and homogenized in the kiln at a high temperature to form a qualified glass liquid; the glass liquid is cooled to the forming temperature through the working channel, and then flows out through the platinum drain plate to form Glass filament: The glass filament is quickly drawn into a glass fiber with a set diameter under the hig...
Example
[0047] Examples 1~6
[0048] The glass fiber is prepared by the tank kiln method.
[0049] The various raw materials are quantitatively transported to the mixing bin according to the proportion, fully mixed and uniform, and qualified batches are obtained;
[0050] The batch materials are transported to the kiln head bin of the tank kiln, and the feeder is fed to the tank kiln at a uniform speed;
[0051] After the batch materials are heated, melted, clarified and homogenized in the kiln at a temperature not exceeding 1330℃, a qualified glass liquid is formed; the glass liquid is cooled to the forming temperature through the working channel, and then flows out through the platinum drain plate to form glass filaments;
[0052] The glass filament is quickly drawn into a glass fiber with a set diameter under the high-speed traction of the wire drawing machine. After spray cooling, coating with sizing agent, and bundling, the wire drawing machine is wound into a cake; in the automatic drying...
