GB/T 2910.1 Quantitative chemical analysis of textiles. Part 1. General rules for testing
3 Principle
The polyacrylonitrile fibers are dissolved and removed from the known dry mass mixture with potassium thiocyanate solution, the residues are collected, cleaned, dried and
Weighing. The corrected mass is used to calculate its percentage of the dry mass of the mixture. From the difference, the mass percentage of polyacrylonitrile fiber was obtained.
4 Reagents
Use the reagents specified in GB/T 2910.1 and this standard.
4.1 65% (mass fraction) potassium thiocyanate solution. 65 g of potassium thiocyanate is weighed and dissolved in water to 100 g. Now with the current use.
Warning --- The agent is harmful to the human body and should be used with perfect protection measures.
5 Equipment
Use the equipment specified in GB/T 2910.1 and this standard 5.1, 5.2, 5.3 and 5.4.
5.1 Conical flask with stopper. The capacity is not less than.200mL.
5.2 Water Bath Oscillator. Keep the temperature at 70°C±2°C.
5.3 Glass sand core.
5.4 Vacuum filtration device.
6 test steps
According to the general procedures specified in GB/T 2910.1 for processing, and then follow the method below.
Place the sample in an Erlenmeyer flask and add 100 mL of potassium thiocyanate solution (4.1) per gram of sample. Tighten the stopper and shake the flask to wet it.
