Polypropylene carbonate (PPC), also known as polyethylene carbonate, has the molecular formula (C4H6O3) n,It is based oncarbon dioxideandPropylene OxideA biodegradable and environmentally friendly plastic synthesized from raw materials. becauseIts production utilizes carbon dioxide, and large-scale application helps alleviate the "greenhouse effect" and reduce "white pollution".
PPC can be degraded into H2O and CO2And it has goodofTransparency, non toxicity, degradability, high barrier properties, biocompatibility, etc; Through plastic modification processing, it can be applied to injection molded basic products, fiber products, blow molded products, etc., and is widely used in the fields of food, packaging, and biomedicine.
The Ubbelohde viscometer is a commonly used instrument for quality testing of polypropylene carbonate (PPC) materials, commonly used to measure the intrinsic viscosity values of PPC materials.
IVS200 Micro Viscometer
IVS200 is an economical automatic viscosity analyzer tailored for small businesses, suitable for measuring the kinematic viscosity, intrinsic viscosity, and molecular weight of polymer materials such as oil/polymers. Realize automatic measurement, automatic cleaning and other functions.
Test Process
1. Weighing samples
Weigh a sample of polypropylene carbonate (PPC) using 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 solution into the dissolution bottle;
2. 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;
3. Viscosity measurement
Open the IVS200 viscometer, set the desired water tank temperature, add the solution to the Ubbelohde viscometer, open the software, perform automatic testing and calculation, and the computer can automatically store the test data;
4. Test results
The IVS200 fully automatic viscosity analyzer is connected to the computer end, which can automatically obtain test results and store them for diversified viscosity data analysis;
5. Clean the viscosity tube
The viscosity tube is fixed in the constant temperature water bath of the IVS200 fully automatic Ubbelohde viscometer, without the need for disassembly and removal, and can be automatically cleaned, discharged, and dried.
