Details: Category: Tungsten Information; Published on Monday, 25 August 2014 14:37; Written by jwy; Hits: 481

For a long time, it has been a persistent pursuit for scientific workers to study and use clean energy. it has been one of research focus to producing hydrogen by using solar water splitting, and the key to achieving this goal is to look for the excellent performance photocatalyst. As tungsten trioxide has good photocatalytic activity in visible range, and it becomes popular, in addition,applications of tungsten trioxide photocatalytic is very extensive, as follows:

1: air purification. In greenhouse tungsten trioxide photocatalyst can remove pollutants in the air by using water vapor and oxygen in the air, such as nitrogen oxides, sulfides, formaldehyde and other harmful gases. In addition, it can also be used to reduce industrial exhaust gas and so on.

2: anti-fog and self-cleaning. Using tungsten trioxide preparation tungsten trioxide film has the same light catalysis, relative to the three tungsten oxide powder with strong hydrophilic, water vapor or liquid droplets in the above form a uniform water film, under ultraviolet light produced by the strong oxidation ability is the adsorption of organic matter is decomposed into carbon dioxide hydrate on anti-fog and self-cleaning effect.

3:antibacterial. Use tungsten trioxide photocatalytic photoproduction of holes and electrons and light catalyst surface adsorption of H2O with strong oxidizing activity of superoxide ion, and bacterial cells or bacteria inside components of biochemical reactions, it can thoroughly kill bacteria, as well as degrade toxic compounds released by bacteria, prevent endotoxin from secondary pollution.

Introduction of Tungsten Filament

Details: Category: Tungsten Information; Published on Monday, 25 August 2014 14:12; Written by jwy; Hits: 452

Brief introduction:

Tungsten filament is widely used as filament for all kinds of lamps.

Tungsten filament is mostly used for making various incandescent and halogen tungsten lamp filament and gas discharge lamp electrode, in addition small amounts of tungsten used for heating material in high temperature furnace, electron tube heater and composite stiffener.

Applications of tungsten filament:

Tungsten-aluminum alloy filament is usually used as filament for high colour temperature lamp and shockproof lamp. Tungsten-aluminum alloy filament is also used as filament for incandescent lamp, high temperature electrodes, tungsten wire in twisted, etc.

We all know the advantages brought by tungsten filament lamp, like tungsten filament can resist high temperature and is able to give out light glows in the current.

At the same time, the disadvantages of tungsten filament are not known to many people. Here are some disadvantages of tungsten filament bulb:

1, Tungsten filament lamp has the mercury pollution in the production process and after using and abandoning it. Nowadays, the western countries attach considerable importance for the mercury pollution.

2. Tungsten filament bulbs are all glass products and glass products are easily to be broken. It is difficult to transport and install tungsten filament bulb.

3. Some of tungsten filament bulbs consume much electricity.

4, Tungsten filament lamp is made of tungsten by drawing. Tungsten filament can easily be damaged and tungsten filament lamp has short service life.

In our daily life, the advantages of tungsten filament lamp are more than the disadvantages of tungsten filament lamp. We cannot live without tungsten filament bulb and the light of tungsten filament bulb!

Characteristics of tungsten filament:

Tungsten filament is featured by high melting point, low vapor pressure. So tungsten filament is suitable to be used in lighting manufacturing. The surface of tungsten filament is smooth and free from any other defects affecting the further uses. The tungsten filament can be easily unwinded. The crystal structure of tungsten filament is compact.

According to the water feature the fishing jigs used in, fishing jigs can be divided into two types, crappie fishing jigs and salty water fishing jigs.

salty-fishing-jigs

And fishing jigs also can be classified into five types due the different head shape of fishing jigs. They are the bullet fishing jigs, football fishing jigs, rocker fishing jigs, mega bite football fishing jig and weedless brush fishing jigs.

rocker-tungsten-jigs

Owing to the different body materials of fishing jigs, there are four types of fishing jigs, bucktail fishing jigs, nylon fishing jigs, Mylar fishing jigs and feathered fishing jigs, of which come in different size and shape. Bucktail jigs, just as the name implies, this kind of fishing jigs have the body made of bucktail .And bucktail jigs are the most popular used between anglers.

Introduction of Tungsten Wire

Tungsten wire applications:

Tungsten wire is usually used to manufacture electric light and electric vacuum components and the high temperature heating body and high temperature structural parts( like filament for all kinds of lamps) and is applied to make vacuum evaporation plating tungsten spiral

Appearance of tungsten wire:

The tungsten wire is coated with colloidal graphite on the surface and tungsten appears uniform black. Tungsten wire appears metal luster if being removed colloidal graphite.

Tungsten wire supply:

We supply pure tungsten wire, tantalum tungsten alloy wire, tungsten copper alloy wire and other tungsten alloy wire. Our tungsten wire supply ability is 10 tons per month.

The delivery time of tungsten wire is 7 to 30 days after confirmation.

Tungsten wire is the best material to make lamp bulb.

In our daily life, there are a lot of metals that can give light besides tungsten filament light bulb, such as copper wire, iron wire, etc.. While, why do we select the tungsten material as the luminous body of bulb? Zhengzhou Sanhui Co., Ltd will explain how tungsten wire give out light to you?

Because the tungsten filament has relatively high electric resistance and melting point, when the electric current goes through the tungsten wire, the electric resistance of tungsten wire rises and gives out heat, then tungsten wire and tungsten alloy wire give out light. At the same time, the melting point of tungsten wire is very high, so tungsten wire is not easily to be burnt out. In addition, inert gas- neon is filled in the bulb, which ensures tungsten wire is not able to be oxidized when the tungsten wire is generating heat. Since the passing of electric current makes the conductor heat. When the temperature of tungsten wire rises, the length of radiated electromagnetic wave becomes short. At room temperature, tungsten wire can radiate ultrared rays. When the temperature rises to a certain degree, tungsten wire begins to radiate visible light, so tungsten wire begins to give out light.

Compared with tungsten wire, other metals would be burnt out before giving out light and also have certain risk. So tungsten wire is the best choice to make bulb.

Fishing Jigs Color Selecting

Details: Category: Tungsten Information; Published on Friday, 22 August 2014 09:11; Written by Sherry; Hits: 563

Generally, a dark colored jig with a big crawfish trailer does a great job imitating a crawfish, and a white color jig does a good job of imitating a baitfish.

It is a reasonable to matching fishing jig color to the water conditions.

In clear water, light colors such as white, chartreuse, green tend to work the best. Because transparent jig skirts and transparent crawfish-type trailers cast less of a silhouette and are less threatening to spooky bass.

While in murky water, black, brown, purple and contrasting dark colors often produce best.
