The full name of aramid fiber is aromatic polyamide fiber, also known as aromatic nylon. It is a linear polymer composed of aromatic and amide groups, which has excellent mechanical properties, stable chemical structure, ideal mechanical properties, ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, light weight, wear resistance and other advantages.
According to different chemical structures, aramid fibers are divided into para aramid, meta aramid, and heterocyclic aramid. Among them, para aramid and meta aramid have a wide range of applications.
Whether it is para aramid or meta aramid, controlling the synthesis of polymers is crucial, with viscosity control being a crucial step
IVS400-6 Fully Automatic Viscometer
Test Process
Weighing samples
Weigh the aramid sample with a one ten thousandth balance and place it in a dissolution bottle. Use a DP25 automatic liquid dispenser (with a transfer accuracy of ≤ 0.1%) to transfer a quantitative concentrated sulfuric acid solution into the dissolution bottle;
Dissolve sample
Place the dissolution bottle into the P12 Zhongwang Polymer Dissolver (which can dissolve multiple samples simultaneously), and use magnetic stirring to dissolve the samples at the specified temperature and time;
Viscosity Test
Open the IVS400 viscometer, set the desired water tank temperature (25 ℃± 0.01 ℃), add the solution to the Ubbelohde viscometer, open the software, perform automatic testing and calculation, and the computer can automatically store the test data;
Test results
The IVS400 fully automatic viscosity analyzer is connected to the computer end, which can automatically obtain test results and store them for diversified viscosity data analysis;
Clean the viscosity tube
After automatic waste disposal, add cleaning reagents for automatic cleaning and drying.
