Tungsten Wire Application - Tubular Halogen Tungsten Lamp

Tungsten wire application is tubular halogen tungsten lamp. Tungsten wire is an important part of the tubular halogen tungsten lamp. According to circulation principle of halogen tungsten lamps, application of tubular halogen tungsten lamps is very wide, it can be used for: chandeliers, bar, KTV, clothing stores, coffee shops and other places. It looks beautiful with small light source at an affordable price, having directional scattering, diffusion and other forms, it still enjoy great popular in the world.

Tungsten Wire Application - Iodine Tungsten Lamp

Tungsten wire application is iodine tungsten lamp. A small amount of tungsten wire are used as a high-temperature furnace heating material, the heater tubes and composites ribs endures, most of them are used as the electrode of incandescent and halogen lamp filament and a gas discharge lamp. Tungsten wire is mad of tungsten bar by forging and drawing, which is mainly used for incandescent lamps, halogen lamps and other electric light source. Iodine tungsten lamp has high brightness and long-life time. Ordinary iodine lamp is used as a light source for cinematography, stage, factories, buildings, squares and so on.

Iodine Lamp Principle:

Incandescent lamps are filled with iodine vapor, and iodine vapor at this time would compound with tungsten, and then decomposit at a high temperature, which would compound tungsten located in other parts of the the tube, then exploded on the filament, such filament does not burn fast because of the hot.

Tungsten Wire Application - LED Lamp

Tungsten wire application is in LED lamp. An LED lamp is a light-emitting diode (LED) product which is assembled into a lamp (or light bulb) for use in lighting fixtures. LED lamps have a lifespan and electrical efficiency which are several times longer than incandescent lamps, and significantly more efficient than most fluorescent lamps, with some chips able to emit more than 300 lumens per watt (as claimed by Cree and some other LED manufacturers). The LED lamp market is projected to grow by more than twelve-fold over the next decade, from $2 billion in the beginning of 2014 to $25 billion in 2023, a compound annual growth rate (CAGR) of 25%. As of 2016, LEDs use only about 10% of the energy an incandescent lamp requires.

Characteristics:

1. Energy conservation: energy consumption of white LED lamp incandescent lamp is 1/10.
2. Long life time: life time is up to 100,000 hours.
3. It can work at high speed: if people frequently turn off and on the energy-saving lamps, the filament will be black, broken soon.
4. Solid package, it belongs cold-light source type. So it is easy transportation and installation, it can be installed in any micro-and closed equipment.
5. LED technology is the rapid progress, its luminous efficiency is astounding breakthrough, prices have also been reduced.
6. Environmental protection without any mercury harmful substances. Assembly parts of LED lamp can be very easy disamounting.
7. Light distribution technology allows LED lamp light source extended to surface light source to eliminate visual fatigue.
8. Integrated design of lens and lampshade. The design makes it have a protective function, avoid wasteful duplication of light, make the product more simple and beautiful.

Tungsten Granule Delivery

Chinatungsten always deliver its tungsten granule by TNT, DHL, FEDEX when gross weight is under 45kgs, between 45kgs~1000kgs, deliver by air, and over 1000kgs by sea. But there are some special points, such as 30kgs to Taiwan by air would be economical than by express. One point to be assured is that Chinatungsten will calculate all the cost and provide the most reasonable one for clients. Sure, the delivery can also be appointed by the clients.

More details, please contact us by email sales@chinatungsten.com.

Tungsten Granule Packing

Regular packing of tungsten granule is 2kgs/2.5kgs in a plastic bag, and vacuumed. Almost Chinatungsten packs 20bags in a drum. For the saving of delivery cost, the outer packing may be paper box if the quantity or gross weigh is not so heavy, which paper box could bear the weight. Tungsten Granule Marking Chinatungsten sticks its packing list with the information of commodity, lot no, size, quantity, N.W, G.W and contract no. If there, the PO no and other information will be marked on the packing list.

Tungsten Granule Application

Tungsten granule is widely used as carbon sulfur analyzer, sulfur analyzer, and the machine is also called CS analyzer, C&S analyzer. With its property of high density, tungsten granule can be oxidized under high temperature, and emits heat, which will show its high heat and quick response. Tungsten granule, as flux in analyzing carbon and sulfur analyzing, decrease boiling point of combustion and speeding the emitting of carbon and sulfur effectively. The other application is filter for its irregular shape and high density, and can be used as fitting parts for welding for its electrode property.

Tungsten Granule CS Testing – Conductivity Method

Used tungsten granule as catalyst, and conductivity method to test carbon and sulfur content is accurate, quick, and sensitive. This method is widely used in testing low content carbon and sulfur.

Use steel as an example to explain this method.

Under 1250~1350 high temperature put steel sample into oxygen atmosphere and burn. The elements of C and S will change to CO2 and SO2. Let the mixed gases into SO2 absorber, the gas will react with re-acid potassium, then sulfate can be made. The solution conductivity value will be changed after the reaction. After that, inflow the remained gas into C absorber, which will react with NaOH and change to Na2CO3 for conductivity value changed. Last, use conductivity method to test the change value and calculate the percentage of carbon and sulfur.

The reaction processes are
4FeS+7O2=2Fe2O3+4SO2
2Fe3C+5O2=6FeO+2CO2
SO2+H2O=H2SO3
3H2SO3+K2Cr2+H2SO4=Cr2(SO4)3+K2SO4+4H2O
CO2+2NaOH=Na2CO3+H2O

Conductivity method is widely used for testing carbon and sulfur content of alloy steel, high temperature alloy, stainless steel, rare earth ductile iron and other tens alloy.
