Ceramic film technology application for cleaner production in biopharmaceutical industry
With the continuous development of membrane technology, the use of membrane separation technology in the biopharmaceutical field is not uncommon. It has the characteristics of easy operation, energy saving, and does not cause new environmental pollution, especially in the extraction of active ingredients of biopharmaceuticals, protoplasm, microbial separation and recovery, clarification and other processes, membrane separation is one of the essential technologies.

Ceramic membranes are a collective term for oxidizing substances. In the true sense, ceramic membranes are composed of substances such as silicon dioxide, titanium nitride (TiN), etc. The ceramic substances used in automotive membranes include tin oxide, indium oxide, tungsten oxide, etc. These substances have a selective filtering function on the solar spectrum, lower reflection, better stability, and remove the characteristics of metal membranes without blocking signals.

Detailed explanation of precision coating methods
The coating roller is a mesh roller with a diameter generally within Φ 20mm- Φ Between 50mm, it is called micro gravure coating, which is a directional and contact coating method. The rotation direction of the micro coating roller is opposite to the feeding direction of the material film, and the material film is not pressurized by the pressure roller on the coating roller.

Discussion on the flame retardant mechanism and performance of flame retardants
Combustion reactions generally consist of three essential elements: combustibles, oxygen, and a certain temperature, all of which are indispensable. The effective mechanism of flame retardants should suppress the production of one or more elements during material combustion, in order to prevent or slow down combustion. The specific flame retardant mechanism of each flame retardant is different, but the basic principle of flame retardant is the same. It reduces the generation of combustible gases during thermal decomposition and hinders the basic reactions during gas combustion, absorbs heat in
