dicho segundo recubrimiento sobre dicho primero. said second coating on said first.
El segundo depósito es una capa de SiOxCyHz (o recubrimiento) de algunos nanómetros de espesor. Más precisamente, el espesor de dicho segundo recubrimiento SiOxCyHz es de aproximadamente 10 nanómetros a aproximadamente 100 nanómetros, preferentemente de 15 a 50 nanómetros, y más preferentemente aproximadamente 30 nanómetros. The second deposit is a layer of SiOxCyHz (or coating) some nanometers thick. More precisely, the thickness of said second SiOxCyHz coating is about 10 nanometers to about 100 nanometers, preferably 15 to 50 nanometers, and more preferably about 30 nanometers.
Usando una relación de aproximadamente 4,5 entre oxígeno y tetrametilsilano en dicho volumen interno del recipiente que forma la cámara de reacción, la composición química de este segundo recubrimiento de SiOxCyHz es la siguiente (análisis de ESCA, FTIR y ERD): Using a ratio of approximately 4.5 between oxygen and tetramethylsilane in said internal volume of the vessel that forms the reaction chamber, the chemical composition of this second SiOxCyHz coating is as follows (ESCA, FTIR and ERD analysis):
Si: 28,5 % Yes: 28.5%
O: 50,55 % O: 50.55%
C: 12,55 % C: 12.55%
H: 8,35 % H: 8.35%
en la fórmula SiOxCyHz siendo x 1,77, siendo y 0,44 y siendo z 0,29 in the formula SiOxCyHz being x 1.77, being y 0.44 and being z 0.29
Usando una relación de aproximadamente 8,5 entre oxígeno y TMS, la composición química de este segundo recubrimiento de SiOxCyHz es la siguiente (análisis de ESCA, FTIR y ERD): Using a ratio of approximately 8.5 between oxygen and TMS, the chemical composition of this second SiOxCyHz coating is as follows (ESCA, FTIR and ERD analysis):
Si: 28,75 % Yes: 28.75%
O: 54,95 % O: 54.95%
C: 8,9 % C: 8.9%
H: 7,4 % H: 7.4%
en la fórmula SiOxCyHz siendo x 1,91, siendo y 0,31 y siendo z 0,257. in the formula SiOxCyHz being x 1.91, being y 0.31 and being z 0.257.
Después del segundo depósito del segundo recubrimiento de SiOxCyHz, la atmósfera reducida se aumenta a la atmósfera ambiente. After the second deposit of the second SiOxCyHz coating, the reduced atmosphere is increased to the ambient atmosphere.
El presente inventor ha descubierto sorprendentemente que el artículo moldeado obtenido tiene una tendencia muy baja a ser teñido durante su vida, siendo este artículo moldeado lavable en un lavavajillas, y pudiendo también ponerse en un refrigerador, un congelador o un horno microondas. The present inventor has surprisingly discovered that the molded article obtained has a very low tendency to be dyed during its life, this molded article being washable in a dishwasher, and also being able to be placed in a refrigerator, a freezer or a microwave oven.
Se hicieron 125 lavados a 85 ºC usando un detergente llamado Neodisher Alka 300 y un agente líquido de aclarado llamado Neodisher TS, suministrado por Dr Weigert Cie. 125 washes were done at 85 ° C using a detergent called Neodisher Alka 300 and a liquid rinse agent called Neodisher TS, supplied by Dr Weigert Cie.
Con el fin de verificar la característica anti-tinción del recubrimiento según la presente invención, se han llenado tazones con diferentes tipos de salsas alimentarias agresivas y productos colorantes y a continuación se suministran a un horno a 80 ºC durante 24 horas. In order to verify the anti-staining characteristic of the coating according to the present invention, bowls have been filled with different types of aggressive food sauces and coloring products and then supplied to an oven at 80 ° C for 24 hours.
La tendencia a ser teñido se observó visualmente antes y después del lavado en lavavajillas. The tendency to be dyed was observed visually before and after dishwashing.
Se obtuvieron resultados muy buenos con los recipientes tratados por el método anteriormente descrito, es decir, se ha observado visualmente que los tazones con un recubrimiento según la invención no se tiñen en comparación con cualquier otro tazón. Very good results were obtained with the containers treated by the method described above, that is, it has been visually observed that the bowls with a coating according to the invention do not stain compared to any other bowl.
El solicitante también ha observado que después de lavar en lavavajillas la superficie del recubrimiento se vuelve muy hidrófila. The applicant has also observed that after dishwashing the surface of the coating becomes very hydrophilic.
El solicitante también ha observado que una relación demasiado alta entre oxígeno y tetrametilsilano implica la formación de un recubrimiento similar a SiOx, que no es resistente al lavado después de varios lavados en un lavavajillas, especialmente a mayores temperaturas. The applicant has also observed that an excessively high ratio between oxygen and tetramethylsilane involves the formation of a coating similar to SiOx, which is not resistant to washing after several washes in a dishwasher, especially at higher temperatures.
El método para la fabricación de un artículo de polímero que tiene un recubrimiento fino formado sobre al menos una de sus caras por plasma comprende sucesivamente: The method for manufacturing a polymer article having a thin coating formed on at least one of its faces by plasma successively comprises:
-un tratamiento con plasma sobre dicho artículo de polímero, ventajosamente un tratamiento con plasma de - a plasma treatment on said polymer article, advantageously a plasma treatment of
argón; -una deposición de un primer recubrimiento de SiOxCyHz por generación de un plasma de tetrametilsilano, argon; -a deposition of a first SiOxCyHz coating by generating a tetramethylsilane plasma,
preferentemente en presencia de un gas oxidante, preferentemente oxígeno O2 o dióxido de carbono, estando el preferably in the presence of an oxidizing gas, preferably O2 oxygen or carbon dioxide, the
valor x entre 0 y 1,7, estando el valor y entre 0,5 y 0,8, estando el valor z entre 0,35 y 0,6 para dicho primer x value between 0 and 1.7, the value being between 0.5 and 0.8, the z value being between 0.35 and 0.6 for said first
