Glass fiber production process

There are two kinds of glass fiber production process: two molding - crucible drawing method, a molding - pool rolling method.

Crucible drawing process a wide range of glass raw materials at high temperature into a glass ball, and then the second glass ball melting, high-speed drawing made of glass fiber precursor. This process has high energy consumption, molding process instability, low labor productivity and other drawbacks, basically a large glass fiber manufacturers eliminated.

Pool kiln drawing method to pyrophyllite and other raw materials in the furnace melting into a glass solution, remove the bubbles after the passage through the transport to the porous hole, high-speed drawing into glass fiber. Kiln can be connected through a number of access to hundreds of leaks at the same time production. This process is simple, energy saving, forming stability, high efficiency and high yield, easy to large-scale fully automated production, become the international mainstream production technology, with the production of glass fiber production accounts for more than 90% of global production.
