What is spraying ECTFE for pharmaceutical three in one equipment
Information summary：Spraying ECTFE on pharmaceutical three in one equipment is a surface coating technology, as follows:
1. Material properties of ECTFE: ECTFE is an ethylene chlorotrifluoroethylene copolymer, which is copolymerized with chlorofluoroethylene and trifluoroethylene. It has excellent chemical stability, can resist the erosion of strong acid, alkali, organic solvent and other chemical substances, and al
Spraying ECTFE on pharmaceutical three in one equipment is a surface coating technology, as follows:
1. Material properties of ECTFE: ECTFE is an ethylene chlorotrifluoroethylene copolymer, which is copolymerized with chlorofluoroethylene and trifluoroethylene. It has excellent chemical stability, can resist the erosion of strong acid, alkali, organic solvent and other chemical substances, and also has good invisibility, electrical insulation, low friction coefficient, high wear resistance, temperature resistance, aging resistance and environmental protection performance. In addition, the molecular structure of ECTFE is compact and has good permeability resistance.
2. spraying process: first of all, the substrate surface of the pharmaceutical three in one equipment should be pretreated, such as cleaning, polishing and applying the pretreatment agent to ensure that the surface is flat and free of impurities. Then, the ECTFE resin and diluent are mixed evenly in a certain proportion and sprayed through a specific spray gun. During the spraying process, it is necessary to correctly control the selection of spray gun, spraying speed, spraying distance and other parameters to ensure the uniformity and thickness of the spraying layer. After spraying, it is also necessary to carry out post-treatment steps such as curing and trimming to make the sprayed layer meet the required performance requirements.
3. role in pharmaceutical three in one equipment:
Anti corrosion: pharmaceutical production will be exposed to various chemicals. The ECTFE coating can prevent the equipment from being corroded, such as resisting the corrosion of acid and alkali solution in the process of cleaning and disinfection, protecting the equipment substrate and prolonging the service life of the equipment.
Ensure drug quality: the coating has good chemical stability and low permeability, which can prevent substances in equipment and materials from dissolving out and mixing into drugs, prevent drugs from being polluted, and ensure the purity and quality safety of drugs. At the same time, its invisibility makes it difficult for the equipment surface to adhere to drugs, which is convenient for cleaning, reduces drug residues and reduces the risk of cross contamination.
Easy to clean and maintain: the low friction coefficient and non stickiness make the surface of the equipment smooth, and the dirt and drug residues are easy to be removed during cleaning. CIP (in situ cleaning) and SIP (online sterilization) systems can be used for efficient cleaning and sterilization, reducing the workload and difficulty of manual cleaning, improving production efficiency, and meeting the requirements of GMP.
