3D Printing - The Future is Now

Posted by Elaine Spitz on Mar 16, 2017 10:17:36 AM

  We're fascinated with the possibilities implicated by the rapid development of faster, cheaper, 
more efficient 3D printers. 3D printing had its advent in 1983, with a printer invented by Chuck Hull called a stereolithographer (SL or SLA), that used UV-curable liquids as its media.

Corrosion Control - Corrosion Inhibitors

Posted by Greg Spitz on Feb 16, 2017 9:16:44 AM

This is fifth in a series on corrosion control; find the other posts here.

Corrosion inhibitors is a bit of an unfortunate term. One could rightly suggest that the entirety of corrosion control is focused on inhibiting corrosion, so any technique used within that umbrella could be called a corrosion inhibitor. Within the corrosion industry (yes, it is a proper industry), corrosion inhibitor refers to chemicals which are applied in low concentration, and which act in one or more of three ways:

Stainless Steel Does Rust

Posted by Greg Spitz on Jan 26, 2017 9:47:17 AM

Since the evolution of the homo sapiens brain, individuals blessed with such a biological marvel have attempted to extract fundamental building blocks from the natural world in order to build tools with which to shape that world. Of course humans are not the only animals capable of making tools from the surrounding environment. That behavior has been observed even in crows (with that in mind I suggest we all be nicer to the crows; if Hitchcock's The Birds is going to happen, the crows will certainly be the organizers, and they might have cleverer plans than just poking our eyes out). But because of that particularly adept and curious brain, humans throughout history have delved ever deeper into what the fundamental building blocks of nature are, along the way developing new techniques and altogether new concepts for tools.

Flexible Packaging a Key to Savings

Posted by Joe Spitz on Jan 17, 2017 7:25:08 PM

In a report by market research firm “Markets and Markets”, it is projected that the flexible packaging industry will have an over 5% annual growth rate, to exceed $125 billion by 2021. In 2016 the market was at $98 billion. Packaging is considered flexible packaging if its shape can be easily changed, and includes any one or a combination of: paper, plastic, film, foil, metalized or coated papers.

Air Pollution in Industrial China

Posted by Elaine Spitz on Jan 6, 2017 11:01:04 AM

The air quality in industrial China has been under scrutiny for some time. Early in 2016, China's environmental ministry announced that just 8 of the country's 74 largest cities passed the government's basic air quality standards in 2014. 

Beijing and other Chinese cities are choking under a blanket of smog. It’s so thick in Tianjin that at times, planes can’t land. In December, authorities issued the first “red alert” of 2016, and 1,200 Beijing-area factories were instructed to reduce production or shut down operations temporarily, in an effort to reduce air pollution, according press reports.

The Real Cost of Corrosion

Posted by Greg Spitz on Dec 14, 2016 9:05:02 AM

Corrosion is one of the most underestimated and often misunderstood forces humans deal with on a daily basis. A large part of that underestimation is the image in many people's minds of what corrosion is.  We tend to think and talk about corrosion similar to erosion: it's a geological time-scale force with which humans not only needn't engage but indeed shouldn't even concern ourselves, as it would be a futile waste of time and energy. Such a submissive attitude toward the natural forces may serve as a satisfactory spiritual practice, but to the discerning member of any competitive economic system, it is simply untenable. While the idea of battling corrosion may then conjure an image of poor Sisyphus and his infinite boulder displacement task, corrosion control can be done effectively and without anguish, as we've seen in our series of posts on the subject. Of course images and possibilities are interesting, but only hard data will tell the real story.

Corrosion Control - Coatings

Posted by Greg Spitz on Nov 10, 2016 1:16:02 PM

This is fourth in a series on corrosion control; find the previous posts here.

Within the world of corrosion control, coatings can include a number of different materials and processes, from paints to plating, to enamel and even bio films. Functionally, however, corrosion control coatings are not so different; they mainly serve one or both of two purposes: physical barrier and sacrificial anode. In order to function as a physical barrier, a material must simply prevent the chemicals which cause corrosion, i.e. water, and oxidizers like oxygen, chlorides or sulfur compounds, from touching the metal being protected. We'll see in a moment how difficult this can be.

Anti-counterfeit Packaging Projections at $154 Billion by 2020

Posted by Elaine Spitz on Nov 10, 2016 1:07:13 PM

It seems to be a daily occurrence where there is news of a breach of some sort, into private lives, or a company's "secure" information, and most assuredly the classified information of our governments. It has been well reported that these are systematic attacks. As the world has become more intricately connected, with increasing individual anonymity, and more "treasures" available, opportunities for thieves to prosper abound.

Crypt of Civilization Time Capsule

Posted by Greg Spitz on Nov 2, 2016 10:34:01 AM

Under seven feet of stone, in the foundation of Phoebe Hearst Memorial Hall, lies a small pool-sized room filled with all of humanity's knowledge prior to 1940.  The room is sealed shut with a welded stainless steel door which is not to be opened until 8113 A.D.  This room is the Crypt of Civilization.

Corrosion Control - Impressed Current Cathodic Protection

Posted by Greg Spitz on Oct 25, 2016 8:12:50 AM

This article is third in a series on Corrosion Control. Read the original over-view here and the post on cathodic protection here.

Impressed current cathodic protection (ICCP) uses the principle of cathodic protection to protect large metal objects in corrosive situations like ships or underground tanks.  As a quick reminder from the second article in this series, cathodic protection uses the galvanic reaction as a benefit to protect smaller metals items.  ICCP is used when the items needing protection are especially large or when fine-tuned control of the galvanic reaction is needed, as can be the case with ships which enter waters of varying salinity.
