Description
Vynález sa týká spósobu merania elektrického náboja pevných materiálov, najma syntetických vláken a filmov, ako aj zariadenia na meranie elektrického náboja.The invention relates to a method for measuring the electrical charge of solid materials, in particular synthetic fibers and films, and to a device for measuring the electrical charge.
Doterajšie spósoby merania elektrického náboja pevných materiálov sú založené na meraní sily elektrického póla v okolí pevných materiálov, ktoré sa prejavujú ako elektricky nabité. Takýmito spósobmi ako aj zariadeniami sa meria len hustota elektrického náboja pevných materiálov aj to nepresne, nakolko vlastně meranie je ovplyvnené prostředím, kde prebieha meranie, ako aj geometrickým tvarom pevných materiálov, u ktorých sa meria hustota elektrického náboja.Current methods of measuring the electrical charge of solid materials are based on measuring the electric pole strength around the solid materials, which are shown to be electrically charged. In this way as well as devices, only the electric charge density of solid materials is measured even inaccurately, since the measurement is actually influenced by the measurement environment as well as the geometric shape of the solid materials in which the electric charge density is measured.
Naviac týmito metodami nie je možné merať celkový elektrický náboj pevných materiálov. Určenie celkového elektrického náboja na základe merania sily elektrického póla je matematickou záležitosťou a vzhíadom na používané spósoby merania je. tiež nepřesné.Furthermore, it is not possible to measure the total electrical charge of solid materials by these methods. Determining the total electrical charge based on the measurement of the electric pole force is a mathematical matter and considering the measurement methods used is. also inaccurate.
Uvedené nedostatky stanovenia elektrického náboja pevných materiálov odstraňuje spósob podlá vynálezu, ktorý spočívá v tom, že elektrický náboj materiálu vo vnútornej komoře sa prejavuje medzi navzájom elektricky odizolovanou vnútornou a vonkajšou komorou napatím, ktoré je velkosti náboja materiálu.
