Foreword
This standard replaces GB/T 5548-1985 "solution stability of the resin finishing agent plus catalyst determination."
The main changes compared to 5548-1985 standard and GB/T as follows.
--- Standard name specification "add resin finishing agent solution was measured after the catalyst stability";
--- Define the scope of room temperature (1985 edition, Chapter 4; edition 6.1);
--- The results are expressed content specification (1985 edition, Chapter 4; edition 6.2);
--- Increasing the content of the test report (Chapter 7 of this edition).
The standard proposed by China Petroleum and Chemical Industry Association.
This standard by the National Standardization Technical Committee Dye (SAC/TC134) centralized.
This standard was drafted. Shenyang Chemical Research Institute.
The main drafters of this standard. Kiran Qin, Shen Jiong day.
This standard was first published in 1985.
After the resin finishing agent plus catalyst
Determination of stability of solution
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.

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.
4.1 Magnesium chloride solution. should be consistent with GB/T 672 provides mass fraction of 50%.
4.2 glacial acetic acid solution. should be consistent with GB/T 676 provides that the mass fraction of 98%.
4.3 ammonium nitrate solution. should be consistent with GB/T 659 provides mass fraction of 30%.
4.4 ammonium sulfate solution. should be consistent with GB/T 1396 regulations, mass fraction of 30%.
