Application of laser particle size analyzer in polylactic acid

Polylactic acid (PLA), as a green and environmentally friendly new material, has expanded its applications from simple packaging and tableware to many fields such as high-tech medical care, textiles and 3D printing. With increasing global emphasis on sustainable development and the control of "white pollution," as well as the continuous progress of PLA modification technology and the gradual reduction in cost, the application prospects of PLA will be even broader.

Particle size distribution is a key bridge connecting PLA materials themselves and their final application performance.

1. For processing, uniform particle size ensures good flowability and uniformity of materials during melt extrusion or injection molding, thereby improving production efficiency and product quality.

2. In 3D printing (such as selective laser sintering), the particle size distribution of the powder directly determines the uniformity of powder spreading and the sintering precision, affecting the details of the finished product.

3. In the field of biomedicine, the particle size of PLA microspheres, which serve as drug carriers, is a core parameter for controlling the drug release rate. A narrow distribution is a prerequisite for ensuring precise and controllable therapeutic effects.

Therefore, particle size testing is an indispensable cornerstone of quality control for optimizing production processes and achieving the expected performance of products.

Laser particle size analyzers play a crucial "quality eye" role in the research and application of PLA. They can quickly and accurately measure the particle size distribution of PLA powder or microspheres, thus directly serving quality control and performance optimization. In 3D printing (such as selective laser sintering, SLS), it ensures that the powder has a uniform and suitable particle size to guarantee smooth powder spreading and sintering accuracy, directly affecting the quality of the molded part. In the biopharmaceutical field, especially for PLA drug carrier microspheres, particle size is the core factor in controlling the drug release rate, and the high-resolution data provided by laser particle size analyzers is the fundamental guarantee for achieving precise sustained-release efficacy. Furthermore, during the production process, it is also a core tool for monitoring the stability of synthesis and pulverization processes, ensuring batch-to-batch consistency of products.

This time, Winner2006 is recommended to test the particle size distribution of polylactic acid. It is mainly used to measure the particle size distribution of particles in solid powders or emulsions, such as cement, ceramics, aerosols, suspensions, etc. This instrument boasts outstanding advantages such as accurate test results, good test repeatability, and high resolution. It is the right choice for wide-distribution particle size testing.
