Titanate coupling agent, as a common material in industry, plays a great role. So when using, we should pay attention to the usage and dosage. Today's edition tells you how to use titanate coupling agent.
Choose titanate coupling agent which need attention 1. First determine the wetness of filler needed, the humidity of titanate coupling agent determines its own characteristics oh, how much amount of titanate coupling agent is used, they are mutually matched, if mismatched, it can not achieve good results, so we must do this step well, and then do it in vain.
2. When choosing titanate coupling agent, many factors should be considered, such as melting point of polymer, crystalline matter, molecular weight, polarity, aromaticity, copolymerization structure and so on. If you use thermosetting polymer, you should also consider its temperature and physical properties.
3. The shape of the filler you use, such as looking at its surface, determining its wet content, acidity and alkalinity, chemical composition, etc., will have a significant impact on the coupling effect.
4. The amount of titanate coupling agent is generally 0% of the physical weight of titanate coupling agent. 5 - 3%, 0. 8 - 1. 5%, its dosage and its effect will not be proportional to oh, if the amount is large, and the coupling agent is excessive, it will be counterproductive, so that other properties decline, the amount is small, titanate coupling agent because of the incomplete inclusion, the effect is not obvious.
Above are the precautions on the dosage of titanate coupling agent. If you are in touch with friends who don't know much about it, please remember.
