Application and advantages of dual planetary mixer in medical adhesive industry

Every year, there are about 114 million surgeries worldwide that cause tissue damage. Surgical patients inevitably suffer from pain during stitches and wound healing, and even infection and inflammation caused by improper wound management. The advent and iteration of biomedical adhesives will hopefully help surgical patients relieve postoperative pain. It can be likened to "human glue" - it can not only bond skin wounds conveniently and quickly, but also repair soft/hard tissue wounds such as internal organs, cardiovascular, bones and teeth, and promote regeneration. With the advancement of medical science, adhesives are increasingly used in the medical field.

There are many types of medical adhesives, which can be divided into the following categories according to their uses:

Soft tissue medical adhesive: Adhesive used to bond skin, organs, nerves, muscles, blood vessels, and mucous membranes.

Hard tissue adhesive: Adhesive used to bond and fix teeth, bones, and artificial joints.

Medical pressure-sensitive adhesive: Basically the same as industrial pressure-sensitive adhesive, the raw materials used are mainly copolymers with acrylate as the main component, combined with natural rubber or synthetic rubber and tackifying resin.

Adhesives for medical devices: The adhesives used are epoxy adhesives, acrylic structural adhesives, UV-curing adhesives, etc.

Adhesives for medical electronic products: Mainly epoxy adhesives, UV-curing adhesives, etc.

The production equipment of medical adhesives is mainly adhesive mixers. Adhesive mixers are classified as follows：

Double planetary mixer

It is suitable for high, medium and low adhesive products (the maximum processing viscosity can reach 1 million cps). For products with different viscosities, there are many different types of agitators, such as paddle type, frame type, twist type, etc., and tooth-type disperser agitators can be added according to the production process; optional configurations include vacuum, heating, cooling and other functions; complete specifications, including laboratory and production equipment, to meet the production of various adhesive products.

Three-shaft mixer

Suitable for medium viscosity adhesive products, with various stirring modes to choose from, including anchor + double dispersion, anchor + dispersion + spiral, anchor + dispersion + paddle, etc.; optional configurations include vacuum, heating, cooling, etc.
