Production process and raw materials

Crucible wire drawing

Clay crucible wire drawing: relatively primitive, eliminated in 1999
Gold-platinum crucible wire drawing: crucible: platinum-rhodium alloy
Pulling platinum crucible: is a new technology researched and developed by our country.

Crucible: pot body: refractory silicon; drain plate: platinum rhodium alloy
The production process consists of two parts: ball making and wire drawing
In the whole drawing process, the ball adding and drawing temperature control are completed by the automatic control device

Pool kiln wire drawing

Pool kiln drawing is a new process for continuous glass fiber production. Pool kiln drawing is to put glass batches in a melting furnace, and then directly draw them into various quantities of continuous glass fibers.

Pool kiln drawing is an advanced technology for producing glass fiber, and its scale and production capacity are far greater than crucible drawing. The technical feature is that it adopts heavy oil or gas heating unit kiln, the powder is directly melted into glass, and the forming channel heated by gas is used to simultaneously draw various specifications of glass fiber raw materials (tens to hundreds). wire. It has the advantages of large production scale, high efficiency, low energy consumption, and good product quality. It can meet the requirements of 800 to 4000 hole large slat wire drawing. It is the best method to produce high-quality, low-cost glass fiber materials.

Compared with crucible wire drawing, pool kiln wire drawing has the following advantages:
1. The ball making process is omitted, the process flow is simplified, and the efficiency is high;
2. Pool kiln wire drawing One kiln can install 10 to hundreds of slip plates, with large melting capacity and high production capacity;
3. Easy to realize automation;
4. Suitable for the production of coarse fiber suitable for glass fiber reinforced plastic with porous large leakage plate;
5. The waste yarn produced is easy to return to the furnace.
