Summer comes, with the increase of sunshine time, ultraviolet ray is also more and more strong. At this time, if the clear pvc pipe manufacturer production of transparent PVC tube after a long time of sun and rain will appear yellow, fading, glossiness decline. So how to make the production of anti-aging, anti-ultraviolet and anti-oxidation of transparent PVC tube? Here is an auxiliary agent.
PVC resin, plasticizer, stabilizer, mixer, RQT-X-1 UV absorber.
All materials to make transparent tube pvc are prepared, and the corresponding weight is determined according to the formula. In a certain order, the prepared materials are poured into the kneader in one time.
The correct order is PVC resin, plasticizer, stabilizer, lubricant, bleaching agent. Generally, the material is kneaded for 45 to 50 minutes at a temperature of 100 to 110 degrees celsius before being removed.
Then you can granulation. In the process of granulationof transparent PVC tube must pay attention to the control of temperature, the highest point of the material temperature is not lower than the melting degree of the material, but also keep lower than the temperature of extrusion molding.
Next is the molding, transparency of transparent PVC tube and molding temperature is closely related. So grasp the molding temperature is the key, the temperature is slightly higher, transparency of forming transparent PVC tube will be relatively high.
Then is traction, the traction speed and the cooling speed of transparent PVC tube will affect its transparency, traction speed is slightly larger, cooling speed is fast, transparency of transparent PVC tube will be higher.
At this time, you can see the transparent PVC tube with RQT-X-1 UV absorber bright color, with more anti-aging antioxidant performance and with eight levels of anti-purple antioxidant color fixing effect.
1. Pay attention to the production temperature of transparent PVC tube, clear pvc tee, anti-aging, anti-ultraviolet and anti-oxidation, it should not be too high.
2. Anti-aging, anti-UV, anti-oxidation raw materials and additives of transparent PVC tube add appropriate and should not be too much.
