Poly (p-dioxane) (PPDO)It is a biodegradable aliphatic polyether ester biopolymer material.This type of polymer has excellent biocompatibility and biodegradability,Widely used in the preparation of medical materials,Gradually replacing traditional materials in clinical applications.In addition, PPDO can also be used in fields such as tissue engineering and fracture repair. It can provide good structural support and promote tissue regeneration, which helps with wound healing and functional recovery.
PPDO not only has excellent mechanical properties and biodegradability, but also has the characteristic of closed-loop recycling The research and development of polymer materials based on PPDO to replace traditional non biodegradable polymers in the field of disposable products is of great significance for solving the resource and environmental problems caused by disposable polymer material products.
Poly (p-dioxane)The intrinsic viscosity and viscosity average molecular weight of PPDO materials need to be measured using the Ubbelohde viscometer method. Intrinsic viscosity and viscosity average molecular weight are important indicators of PPDO materials.
The Zhongwang Fully Automatic Viscometer IVS400 is designed with the Ubbelohde Viscometer as its core, complying with relevant standards such as ISO, GB, DIN, etc. It realizes fully automated testing processes such as automatic cleaning, automatic measurement, automatic calculation, automatic waste discharge, and automatic drying, and the timing accuracy can be precise within 0.001s. It provides a stable and uniform temperature field of ≤± 0.01 ℃ for testing, ensuring the accuracy of experimental data.
Test Process
Weighing samples
Weigh a sample of poly (p-dioxanone) (PPDO) using a one in ten thousand scale 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 to 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 measurement
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, cleaning reagents are automatically added for automatic cleaning and drying.
