Each machine must be operated strictly according to the operating procedures during use. This is not only for the maintenance of multiple machines, extending their lifespan, but also for the safety protection of operators. During use, X-ray fluorescence melting instrument What are the precautions to take before operation?
As we all know, the X-ray fluorescence melting instrument is a professional supporting equipment for the fusion method of X-ray fluorescence analyzer. It adopts a touch screen control method. The machine interface is user-friendly and easy to operate. The automation degree of the whole machine is relatively high. It can be widely used in sample preparation in the steel, chemical, geological, metallurgical, cement, and ceramic industries, as well as in the detection of refractory materials. The X-ray fluorescence melting instrument has the characteristics of fast heating, temperature control, energy saving, and stable operation. The temperature can reach as high as 1100℃, which has a different melting effect on refractory materials. The selection and use of crucibles for the X-ray fluorescence melting instrument is also a key aspect. During use, it should be noted that the X-ray fluorescence melting instrument cannot be used to process halogens or substances that can release halogens in platinum containers, such as aqua regia, bromine water, and oxidant mixtures, because ferric chloride solution has a significant corrosive effect on platinum. Moreover, platinum crucibles must not come into contact with any other metals during heating. All platinum containers should be heated or burned in an electric furnace or gas lamp oxidizing flame, and should not come into contact with smoky flames or the inner cone of the flame to avoid the formation of brittle platinum carbide.
The safety precautions during the use of the X-ray fluorescence melting instrument are mandatory for both manufacturers and users. First, the instrument must be grounded, which is very important. The instrument has already connected the ground wire to its shell to ensure safety. During use, do not directly observe the high-temperature furnace with the naked eye, as this will damage the eyes due to hot gas and radiation, causing unnecessary harm. Before starting the melting process, make sure the furnace door is closed. During the melting process (while the furnace is moving), do not open the furnace door or place your hands or other objects near the furnace door to prevent injury and damage caused by the furnace movement! When opening and closing the furnace door cover, do so gently to prevent the glass door from breaking. According to user needs, the furnace door cover can be removed. For customers who use the X-ray fluorescence melting instrument for more than 6 hours a day, the instrument top cover should be opened during operation. When placing and removing samples with crucible tongs, wear gloves. Be extra careful when using crucible tongs to prevent burns, sample drops causing burns, damage to other items, and sample damage.
