Safeguard Your Cameras

Cameras and lenses are very susceptible to moisture damage.

Moisture is the enemy of camera equipment because it causes rust, mildew, corrosion, and even nurtures the growth of lichens and mold.Today’s digital cameras have delicate electronic circuitry which is susceptible to even trace amounts of moisture. Camera collectors know that older cameras have parts made of felt, cloth, leather, and water-soluble glue.These materials act like sponges, holding enough moisture to create an environment where something may eventually grow in your camera or lens.

191ec462090ac24f55f231d416aef6af.jpgExcess humidity is destructive to cameras.

Mold, mildew, and even lichens can actually feed on lens coatings as well. They create a spidery tracing on the surface of your lens elements, and eventually creep inside the lens! Even though lenses are made of materials that won’t absorb moisture, they need to be protected from a moist environment.

You need to protect your camera gear from moisture no matter how old or new it is. It doesn’t take much moisture to cause damage.

955e7f1c9a63c4a550bda1d3b8ae05c8.jpgFungus that forms between lens elements and under lens coatings in humid, dark environments is either practically impossible or extremely expensive to remove.

Our sealed Camera Lens Super Dessicant get units dehumidify long-term storage and offer protection from sudden downpours or other water contact with cameras and lenses. When the color indicator shows that the unit is saturated, pop it in the oven to bake out the moisture, and put it right back in your camera.

About Alumina ceramics   Al2O3

Alumina ceramics Al2O3 are one of the most durable ceramics available. The outstanding properties of alumina ceramics make it one of the most widely used ceramics in structural, wear and corrosion environments. In addition, high purity alumina ceramics have become one of the commonly used materials for semiconductor cavity applications due to their excellent electrical properties.

Application

Al2O3 is an electrical insulator but has a relatively high thermal conductivity (30 Wm−1K−1)for a ceramic material. Aluminium oxide is insoluble in water.
In its most commonly occurring crystalline form, called corundum or α-aluminium oxide, its hardness makes it suitable for use as an abrasive and as a component in cutting tools.

2. wafer transmission parts

3. Parts for production equipment of Flat panel display

4. thermal and electrical insulating parts


Other Application:


A. illers

Being fairly chemically inert and white, aluminium oxide is a favored filler for plastics. Aluminium oxide is a common ingredient in sunscreen and is sometimes also present in cosmetics such as blush, lipstick, and nail polish.

B. Glass

Many formulations of glass have aluminium oxide as an ingredient.

C. Catalysis

Aluminium oxide catalyses a variety of reactions that are useful industrially. In its largest scale application, aluminium oxide is the catalyst in the Claus process for converting hydrogen sulfide waste gases into elemental sulfur in refineries. It is also useful for dehydration of alcohols to alkenes.

Aluminium oxide serves as a catalyst support for many industrial catalysts, such as those used in hydrodesulfurization and some Ziegler-Natta polymerizations.

D. Water purification

Aluminium oxide is widely used to remove water from gas streams.

E. Abrasive

Aluminium oxide is used for its hardness and strength. It is widely used as an abrasive, including as a much less expensive substitute for industrial diamond. Many types of sandpaper use aluminium oxide crystals. In addition, its low heat retention and low specific heat make it widely used in grinding operations, particularly cutoff tools. As the powdery abrasive mineral aloxite, it is a major component, along with silica, of the cue tip "chalk" used in billiards. Aluminium oxide powder is used in some CD/DVD polishing and scratch-repair kits. Its polishing qualities are also behind its use in toothpaste.

F. Paint

Aluminium oxide flakes are used in paint for reflective decorative effects, such as in the automotive or cosmetic industries.

G. Composite fiber

Aluminium oxide has been used in a few experimental and commercial fiber materials for high-performance applications, Alumina nanofibers in particular have become a research field of interest.

H. Body armor

Some body armors utilize alumina ceramic plates, usually in combination with aramid or UHMWPE backing to achieve effectiveness against even most rifle threats. Alumina ceramic armor is readily available to most civilians in jurisdictions where it is legal, but is not considered military grade.

I. Abrasion protection

Aluminium oxide can be grown as a coating on aluminium by anodizing or by plasma electrolytic oxidation. Both the hardness and abrasion-resistant characteristics of the coating originate from the high strength of aluminium oxide, yet the porous coating layer produced with conventional direct current anodizing procedures is within a 60-70 Rockwell hardness C range which is comparable only to hardened carbon steel alloys, but considerably inferior to the hardness of natural and synthetic corundum. Instead, with plasma electrolytic oxidation, the coating is porous only on the surface oxide layer while the lower oxide layers are much more compact than with standard DC anodizing procedures and present a higher crystallinity due to the oxide layers being remelted and densified to obtain α-Al2O3 clusters with much higher coating hardness values circa 2000 Vickers hardness.

J. Electrical insulation

Aluminium oxide is an electrical insulator used as a substrate (silicon on sapphire) for integrated circuits but also as a tunnel barrier for the fabrication of superconducting devices such as single electron transistors and superconducting quantum interference devices (SQUIDs).

For its application as an electrical insulator in integrated circuits, where the conformal growth of a thin film is a prerequisite and the preferred growth mode is atomic layer deposition, Al2O3 films can be prepared by the chemical exchange between trimethylaluminum (Al(CH3)3) and H2O:

2 Al(CH3)3 + 3 H2O → Al2O3 + 6 CH4

H2O in the above reaction can be replaced by ozone (O3) as the active oxidant and the following reaction then takes place:

2 Al(CH3)3 + O3 → Al2O3 + 3 C2H6

The Al2O3 films prepared using O3 show 10~100 times lower leakage current density compared with those prepared by H2O.
