Description

COMPOSICIÓN LIMPIADORA Y ACONDICIONADORA DE CONTACTOS ELÉCTRICOS COMPOSITION CLEANING AND CONDITIONING OF ELECTRICAL CONTACTS
MEMORIA DESCRIPTIVA CAMPO DE LA INVENCION DESCRIPTIVE MEMORY FIELD OF THE INVENTION
La presente invención consiste en una composición limpiadora y acondicionadora, atóxica y no inflamable, aplicable a todos los contactos o conexiones eléctricas de media y alta tensión, asi como a los de baja tensión y alta corriente como los utilizados en los procesos de electro .obtención y electro refinación de metales.  The present invention consists of a non-flammable and non-flammable cleaning and conditioning composition, applicable to all medium and high voltage electrical contacts or connections, as well as to low voltage and high current contacts such as those used in electro. and electro metal refining.
ANTECEDENTES DE LA INVENCION BACKGROUND OF THE INVENTION
En todos los procesos que utilizan contactos eléctricos como elementos de conexión o conducción eléctrica es frecuente que sobre la superficie de estos se forme una -delgada capa de óxido que cubre el área de contacto eléctrico, la cual inicialmente suele ser un pequeño punto de oxidación que podría tener poco efecto en la conductividad total de los contactos. Sin embargo, cuando la capa de óxido se extiende hasta un área significativa, el área de contacto relacionada con la corriente se reducirá, incrementando de esta manera su resistencia eléctrica. Un aumento en la resistencia eléctrica aumentará la temperatura de contacto, lo cual puede significar en importantes pérdidas de energía y finalmente en la destrucción del contacto. Este fenómeno es especialmente notorio en los procesos de electro obtención (EW) y electro refinación (ER) de metales como el cobre y el zinc, los cuales se realizan en grandes naves que contienen las celdas electrolíticas en las que se electroliza un electrolito compuesto por sulfato de cobre y ácido sulfúrico, conectando el polo positivo de una fuente de poder de corriente continua a un electrodo de plomo en el caso de la EW o de cobre blíster en caso de la ER. Por su parte, el polo negativo de la fuente de poder se conecta a un electrodo de acero inoxidable en el caso de la EW o una delgada lámina de cobre en el caso de la ER. Mediante este proceso, se logra que el' metal presente en el electrolito se deposite en el cátodo. In all processes that use electrical contacts as connection or electrical conduction elements, it is common that a thin layer of oxide is formed on the surface of these that covers the area of electrical contact, which initially is usually a small point of oxidation that It could have little effect on the total conductivity of the contacts. However, when the oxide layer extends to a significant area, the current-related contact area will be reduced, thereby increasing its electrical resistance. An increase in electrical resistance will increase the contact temperature, which can mean significant energy losses and ultimately the destruction of the contact. This phenomenon is especially noticeable in the processes of electro obtaining (EW) and electro refining (ER) of metals such as copper and zinc, which are carried out in large ships containing the electrolytic cells in which an electrolyte composed of Copper sulfate and sulfuric acid, connecting the positive pole of a DC power source to a lead electrode in the case of EW or copper blister in the case of ER. On the other hand, the negative pole of the power source is connected to a stainless steel electrode in the case of the EW or a thin copper foil in the case of the ER. Through this process, it is achieved that the 'metal in the electrolyte is deposited on the cathode.
Los cátodos al interior de las naves de electro obtención se recubren con el metal a obtener por tiempos de entre 6 a 8 días, luego se retiran y son rápidamente reemplazado por otros- nuevos en un proceso llamado cosecha de cátodos.  The cathodes inside the electro-obtaining ships are coated with the metal to be obtained for times between 6 to 8 days, then removed and quickly replaced by new ones - in a process called cathode harvesting.
Tanto en el caso de la EW como en la ER se (deposita el metal con voltajes entre 0,1 a 1,7 Volts e intensidades de entre 100 y 350 amperes por metro cuadrado de cátodo. Producto de la electrólisis se libera al medio ambiente de las naves una importante cantidad de niebla ácida, que se forma al escapar a la atmósfera el oxígeno que genera la electrólisis, arrastrando con él parte del electrolito.  Both in the case of the EW and in the ER the metal is deposited with voltages between 0.1 to 1.7 Volts and intensities between 100 and 350 amps per square meter of cathode. Product of the electrolysis is released to the environment of the ships an important amount of acid fog, which is formed by escaping into the atmosphere the oxygen generated by electrolysis, dragging part of the electrolyte with it.
La niebla ácida conlleva grandes problemas a las empresas mineras debido a lo corrosivo y tóxico de su composición. Genera corrosión en toda la nave y principalmente en los puntos de contacto eléctrico de las celdas formando capas de óxidos y sulfatos que disminuyen la conductividad eléctrica en ellos generando asi importantes pérdidas de energía. Las empresas mineras consideran que cerca de un 2 a 3% de pérdida de la energía es aceptable, sin embargo, esto representa un enorme gasto de recursos económicos y naturales. Acid fog causes major problems for mining companies due to the corrosive and toxic composition. It generates corrosion throughout the ship and mainly at the points of electrical contact of the cells forming layers of oxides and sulfates that decrease the electrical conductivity in them thus generating significant energy losses. Mining companies consider that about 2 to 3% of energy loss is acceptable, however, this represents a huge expense of economic and natural resources.
En el estado del arte se proponen diversas composiciones para la limpieza y preservación de contactos eléctricos, como por ejemplo el documento WO9403934 que propone una composición para la limpieza del contacto eléctrico entre superficies de metal de un dispositivo de batería, en donde dicha composición consiste de un agente de limpieza orgánico volátil capaz de desplazar partículas en una superficie de contacto de metal abrasivo y un agente de oclusión oxidante, contacto adherente, untable y no volátil capaz de formar una película continua en dicha superficie de metal.  Various compositions are proposed in the state of the art for cleaning and preserving electrical contacts, such as WO9403934, which proposes a composition for cleaning the electrical contact between metal surfaces of a battery device, wherein said composition consists of a volatile organic cleaning agent capable of displacing particles on an abrasive metal contact surface and an oxidizing occlusion, adherent, spreadable and non-volatile contact agent capable of forming a continuous film on said metal surface.
Por su parte, el documento US 3421872 divulga una composición limpiadora de contactos que comprende una mezcla viscosa de grafito en polvo entre 2 a 8% en peso, piedra pome entre 25 a 40% en peso y grasa corporal entre 40% a 60% en peso, dicha composición siendo no fluyente a temperatura ambiente.  For its part, US 3421872 discloses a contact cleaning composition comprising a viscous mixture of graphite powder between 2 to 8% by weight, pome stone between 25 to 40% by weight and body fat between 40% to 60% in weight, said composition being non-flowing at room temperature.
Por otro lado, el documento US 6342471 divulga un limpiador en aerosol para uso en tableros de circuito y conectores eléctricos que comprende un solvente con un potencial de agotamiento de ozono bajo; un propulsor de tetrafluoretano , en donde el solvente está presente en concentraciones de a- lo más 50% en peso y el propulsor está préseme en concentraciones de al menos 50% en peso, donde el limpiador exhibe características de limpieza cercanas a 0.25 mi de suciedad por gramo de limpiador entregado. On the other hand, US 6342471 discloses an aerosol cleaner for use in circuit boards and electrical connectors comprising a solvent with a low ozone depletion potential; a tetrafluoroethane propellant, wherein the solvent is present in concentrations of at most 50% by weight and the propellant is me in concentrations of at least 50% by weight, where the cleaner exhibits cleaning characteristics close to 0.25 ml of dirt per gram of cleaner delivered.
A partir de las composiciones del estado del arte, se observa que estas no resultan adecuadas para la mantención de los puntos de contacto eléctrico de modo intensivo, esto porque las formulaciones y presentaciones de los limpiadores de contactos y pule metales conocidos implican el uso de compuestos tóxicos, muchas veces volátiles, inflamables y que provocan daño a la capa de ozono.  From the compositions of the state of the art, it is observed that these are not suitable for the maintenance of the electrical contact points intensively, this because the formulations and presentations of the contact cleaners and polishes known metals involve the use of compounds toxic, often volatile, flammable and causing damage to the ozone layer.
Además, estas composiciones no son aplicables a la exigente industria minera, específicamente al campo de limpieza de superficies de contactos eléctricos utilizados para la electro obtención o electro recuperación ya que sus componentes tóxicos e inflamables contaminan el electrolito y ponen en riesgo la salud de los trabajadores.  In addition, these compositions are not applicable to the demanding mining industry, specifically to the field of cleaning electrical contact surfaces used for electro obtaining or electro recovery since their toxic and flammable components pollute the electrolyte and put workers' health at risk .
Por lo tanto, el objetivo de la presente invención es superar los inconvenientes que presentan los productos limpiadores del estado del arte mediante una composición limpiadora y acondicionadora de contactos eléctricos no tóxica ni inflamable, la que al ser usada sobre los puntos de contacto elimina todo tipo de impurezas incluyendo óxidos y sulfatos y también genera una superficie de contacto más lisa y con mayor cantidad de puntos de contacto.
