With the further promotion of the "plastic restriction order", the promotion of biodegradable plastics is increasing, and the degradation standards are becoming higher. PGA materials have gradually become the focus of the industry. And viscosity is one of the important indicators in the quality control of PGA material applications.
Polyglycolic acid (PGA), also known as polyhydroxyacetic acid, is a type of alcohol with the least number of carbon units and the ability toThe ester structure of decomposition and the fastest degradation rate of aliphatic polyester polymer materials.
The application of PGA is mainly manifested in two aspects: biomedical and ecological. Biomedical applications mainly include medical sutures, drug controlled release carriers, fracture fixation materials, tissue engineering scaffolds, suture reinforcement materials, etc; Ecological applications are beneficial to the environmentBiodegradable plastics are used to replace non degradable plastics in the traditional plastic industry.
For the increasingly severe 'white pollution',
The natural degradability of polyglycolic acid is of great significance,
Minimize the impact of plastic waste generated in human life on the environment.
IVS800 Fully Automatic Viscosity Measurement System
The Zhongwang fully automatic viscosity measurement system IVS800 achieves a fully automated measurement process based on the Ubbelohde viscosity method as the core measurement method. Significantly improved the accuracy of counting, temperature control range, and temperature field uniformity during the testing process.
Test Process
1
solution preparation
Weigh the polyglycolic acid using a one ten thousandth scale, place it in a dissolution bottle, and use a DP25 automatic liquid dispenser (with a precision of pipetting)≤0.1%）Transfer a quantitative amount of solvent to the dissolution bottle;
2
Dissolve sample
Place the dissolution bottle into the P12 Zhongwang Polymer Dissolver and dissolve the sample using magnetic stirring at the specified temperature and time;
3
Viscosity measurement
Plant polyglycolic acid (PGA)Place the sample dissolution bottle into the IVS800 sample tray with the pre-set water tank temperature, activate the testing function, and automatically obtain the test results;
4
Test results
The IVS800 fully automatic viscosity measurement system 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 IVS800 viscosity analyzer, without the need for disassembly and removal, and can be automatically cleaned, discharged, and dried.
