GB/T 5548-2007Resin finishing agent - Determination of the sability of solution after adding catalyst (English PDF)

1 Scope

This standard specifies the method for measuring the stability of solution after adding catalyst resin finishing agent.

This standard applies to the determination of the stability of the solution a catalyst for the resin finishing agent.

2 Normative references

The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent

Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research

GB/T 659 chemical reagent ammonium nitrate

GB/T 672 chemical reagent magnesium chloride hexahydrate (magnesium chloride)

GB/T 676 chemical reagent acetic acid (glacial acetic acid)

GB/T 1396 chemical reagents sulfate

GB/T 6682 analytical laboratory use specifications and test methods (GB/T 6682-1992, neq ISO 3696. 1987)

Principle 3

Adding an acidic reaction in aqueous solution of a certain amount of resin finishing agent, the catalyst is placed at a certain temperature to observe whether there is cloudy

Or precipitation. In time turbidity or precipitation indicates its stability.

4 Reagents and materials

Unless otherwise specified, use only water for the three confirmed analytically pure chemical reagents and GB/T 6682 stipulated.
