Analysis of surface treatment technology before aluminum and aluminum alloy coating

[China Aluminium Network] Chemical conversion film treatment is currently used in aluminum and aluminum alloy anti-corrosion surface treatment of a wide range of processes, more than half a century of the development of the chemical conversion film process is maturing, and continue to derive other new treatment method. Undoubtedly, chemical oxidation will still play an important role in the future. However, due to the increasingly serious environmental pollution, higher requirements have been placed on the cleanliness and non-pollution of the surface treatment process. This can be improved from the following directions.

1. Low-temperature metal surface pretreatment An energy-saving surface treatment process has been developed.

2, low chromium and chromium-free treatment.

3, waterless wash treatment: cancel the entire process of washing process, in addition to fundamentally solve the problem of environmental pollution caused by wastewater discharge, but also save water. Japan reported: Chromic acid type surface treatment agent, is a mixture of Cr3+, Cr6+ and water-soluble organic resin, used in aluminum plate, using spraying filming method, no need to wash, even if chromium ion does not pollute the environment; naturally dry, easy to close System treatment; film corrosion resistance and coating adhesion are the same as or better than those of past surface treatments.

4. The pre-treatment process and the film formation process adopt an inter-closed cycle mode, in which all chemical agents in the system are recycled, and do not need to replace the original liquid, but only periodically add the consumables; the water-washing treatment or the non-washing treatment can achieve the sealing. The closed process can greatly improve the on-site operation environment, reduce the discharge of waste slag and waste liquid, save energy and resources, and the economic and social environmental benefits are obvious.

Economical Coutinues Rim Blades
These new blades have diamond throughout the edge and cut aggressively. blades also last a long time, because the diamond isn't just plated on top of the rim. Instead, diamond particles are incorporated into the actual metal of the rim. Cut blades up to 10" in diameter work great with water, but we advise using an additive such as Lube Cool 4800. If you use oil, these long-lasting blades will last even longer! Cut blades have a continuous rim.
Precision Sineterd Saw Blades
Precision Continuous Rim Lapidary Blade is a professional quality blade manufactured using a high concentration of premium grade industrial diamonds.  These blades will cut faster than regular notched rim blades and the smaller size thin core blades can be used when cutting valuable materials to minimize loss of material.  A full diamond sintered blade, The BD 303 blades can be used with rust inhibiting water coolants although oil coolants will result in longer blade life. 
Notched Rim Lapidary Blade
Notched Rim Lapidary Blade are excellent quality commerical grade blades, designed for use on hard lapidary materials like agate, jasper, petrified wood, and geodes.More diamonds in the notched rim and a stiffer core make this blade cut faster and provide a long use-life. Covington Gold blades are a great low cost choice for your lapidary saw.
Coarse Cut Notched Blades
COARSE CUT DIAMOND SAW BLADES IF YOU CUT HARD MATERIAL YOU WILL LOVE MY COARSE BLADES
Red Thin Rim Sintered Saw Blade

These thin rim sintered diamond saw blades last longer than notched blades.The diamonds (325#/400#) are secured into a metal bond that extends the full depth of the rim. Diamonds are continuously exposed as the edge of the blade wears away cut after cut. They offer a long life and clean, thin cuts. Click to enlarge the image to see a close-up of the diamonds secured in the rim.

Precision Diamond Loop Wire Saw and Equipment in producing non-destructive, non-deforming cut or slice.Application used in cutting precious metals, plastics, quartz, glass, graphite and ceramics are just some of the many natural and synthetic materials that in Research and Development, Quality Control, Failure Analysis and Production.

Additional Applications Tire section cutting,geology,archaeology,paleontology,criminology,forensic,biology,pathology,histology,anatomy,dentistry.We also can supply the wire saw suit for the MTI,WELL,Gaoce and others Brand machine.

Diamond Loop Wire Saw is one of the most flexible cutting tools, which can set on the surface of diamond crystals. While cutting, the diamond wire will move from one direction with the speed from 30-60 m/s. It will give users the great advantages. Widely used on cutting the rubber machine and hard surface of materials,such as,tire Section cutting machine,Tyre section cutting machine,artificial crystal (sapphire, silicon),Special Ceramic,Precious metal,graphite and plastic,brittle material. Also used on research field: geology,archaeology,architecture and biology etc. Also supply the diamond loop wire saw for tire section cutting machine.

A) 0.5-1.0mm Diameter application in artificial crystal,gem,ceramic and precious metal etc.

B) 1.0-3mm diameter application in graphite,plastic,rubber,concrete,fiberglass and foamed cement etc. Specification

1. High efficiency on cutting, while the speed from 30 to 60 m/s

2.Diameter from 0.3-3.0 mm,Length from 800-100000 mm and math for the popular machine in current market 3.Cutting fits into both wet or dry environment

4.Cutting directions could change by customer's requirement. And also could apply to cut the curved surface.

5. Operation and Replacement of diamond wire are really convention.
