How To Identify The Quality Of PVC Raw Materials

Tricks 1
Using muffle furnace to burn ash
In everyone's attention, some PVC manufacturers even began to add a small amount of calcium powder, you believe it? With Muffle, you can all of your raw materials are tested again Oh, muffle economic and affordable, what calcium carbonate, calcium granules, talcum powder, all too muffle "Samadhi real fire."
Tricks 2
Measuring melting point with melting point instrument
Lubricant of a relatively important performance indicators, such as PE wax melting point in general in 105-110 ℃, some manufacturers doped paraffin or hardened oil, melting point will be reduced.
Tricks 3
Determination of stability of raw materials by torque rheometer
The use of Rheometer is broader, can determine the processing of ACR, can also determine the stability of various raw materials, if the quality is different, the curve will certainly show, but also to determine the stability of the dynamic stability of the stabilizer, is a machine in hand, buy material worry-free.
Tricks 4
Testing PVC by Oven method
Some raw materials may be doped PVC, are hard to identify the powder, using oven contrast detection, 150° a certain time, first discoloration and red, raw materials may contain PVC.
Tricks 5
Smell to determine the waste added
If the purchase of raw materials have a pungent odor, the raw material may be mixed with foreign waste, or the production process using cheap or inferior raw materials produced, perhaps not too much for your production, but the subsequent performance of the products have a greater impact.
