Activated Zeolite Powder Q&A PART 2

Publisher:adminDate:2017-07-31

Q6:What is the temperature that the activated zeolite powder can absorb in the glue?
A6:500 degrees below no problem, the original molecular sieve powder at 550 degrees, high temperature baking will lose crystallization water, when the temperature dropped to room temperature, will slowly absorb moisture recovery.When the calcination temperature is 900 degrees, the crystal structure is destroyed and can not be recovered, nor is it water absorbent. So the activation powder is acceptable at temperatures below 500 degrees celsius.

Q7:What is the recommended amount of activated zeolite powder?
A7:The amount of activating powder is determined according to the amount of water needed to be removed from the system. The static water absorption at 24 means that in the ideal state, the water absorbed by the activated powder is 24%. of its own weight.

Q8:Will the ctivated zeolite powder affect the viscosity of the glue?
A8:The activated zeolite powder does not have the effect of increasing viscosity, and the effect on the viscosity of the system is only the influence of other inorganic materials

Q9:Can the activation powder be added to polyols?
A9:The two-component polyurethane A component is generally polyester polyol and polyether polyol, activation powder is generally added to the A component.

Q10:Will the activation powder spit water, for example, in ink?
A10:No. Activation powder is also a kind of molecular sieve, which belongs to static molecular sieves and can not be regenerated in the system. Molecular sieve adsorption, desorption is conditional, desorption needs high temperature and low pressure, the use of the customers, the activated molecular sieve powder is formed of resin with homogeneous material, does not have the desorption conditions, which is why the activation powder not renewable. (resin is one of the materials of certain inks).
