Pineapples, oceans & refrigerated containers

Standard

Shipping containers

At first you might be wondering what these three things have in common, but the answer is rather obvious. Pineapples will only grow successfully in certain geographical areas. For the rest of us, living in less exotic parts of the world, they become accessible because they are shipped around the world on great big ships, crossing the oceans. All the while, pineapples (and other tropical fruits, naturally) are stored in refrigerated containers. To make sure the produce stays fresh all the way to its final destination, the containers must be sealed really well. Which is where the Teroson branded sealant, Teroson MS 930 comes in.

One of the things that can change the properties of the seal and eventually cause failure of the product used is UV radiation. And there’s plenty of that on ships crossing oceans for weeks at a time. That’s why it’s extremely important that the sealant used is resistant enough to UV radiation to keep its full properties for the duration of the trip. Otherwise the beloved tropical delicacies might reach us looking rather less than appetising.

Is adhesive a solution for you?

Standard

is adhesive a solution

We’ve talked about ways to select the correct adhesive, and what to keep in mind when making a decision. I’ve also mentioned how important it is to have realistic expectations, whether you’re repairing something by using adhesives or producing something completely new.

However, I’m thinking you might want to have it made easier for you and find more information, relating specifically to your type of industry or activity. In which case this web solution finder might be the first place to start. Other than giving an overview of the main adhesive (and sealant) groups and their most important capabilities, you’ll also find examples of industries and industrial items on which they work. In the same site you can see the real life examples of the companies currently using adhesives in their manufacturing. And of course, as always, I cannot stress this enough – for your final decision, always involve an expert.

 

It’s all about trust

Standard

testing equipment

I would like to say a few words this time about what happens with an adhesive between the moment it comes out of the research and development, and the moment the formulation is sent into actual commercial production. People often wonder how much trust they can put in, often a very thin layer of a chemical to withstand loads or temperature variations, moisture or harsh chemicals, such as those occurring on oil platforms, roller-coasters, fire trucks, tunnel drilling equipment… I could keep going for very long just listing different applications. Naturally, every smart engineer will always want to test any adhesive, sealant or other chemical product in real life conditions, and I totally encourage that.

However, I just wanted to point out how much testing, and how rigorous, happens already far before any adhesive goes into sales. When it comes to Loctite products, there are several tests done to observe mechanical properties like shear strength, physical properties like thermal conductivity, or resistance properties like temperature and chemical resistance. You can see more  here. Normally, it’s also possible to design custom made tests on customer request. Locally based technical sales engineers  will be happy to help with that.

We love machines!

Standard

Machinery

 

It’s something that an average person seldom thinks about, but practically everything we use in our every-day lives was made using some sort of a machine. Mechanisation and automation made modern industry what it is today and in fact, started a whole new industry segment: manufacturing of industrial machinery.

Whether we are talking about food processing machines, metal-working, mining and rock processing equipment or sophisticated robots, every manufacturer pretty much wants the same things: to design and manufacture a reliable, efficient and durable machine, which will ensure they never hear back from their customers in the form of claims or complaints. No loose screws allowed, no  leaky threaded fittings, no faulty metal components… That’s where engineering adhesives (or anaerobics as we sometimes call them) come so handy. They help lock all threaded fasteners and seal pipe threads and flanges, without making you keep stock of all the different size gaskets and seals.

But even outside of these, what I would call basics, adhesives can be used in the very structure of your machine and replace some of the traditional joining methods, whether it’s to reduce weight of the machine, achieve more efficient design, increase reliability… In such cases it’s best to involve adhesive experts in early design stages. They will always be happy to work with you on achieving the design both you and your customers will be happy with, but meanwhile you can explore your options in general, or see some examples based on the real life cases.

Splitting atoms: nuclear power generation

Standard

While safety is a crucial point in any of the power plants, in nuclear power generation danger and safety take on a whole new dimension. That’s why any of the maintenance materials used need to be rigorously checked and specially approved. And also suppliers of products need to be more than just a supplier and act as partners and solution providers.

It’s not just about finding the right product to prevent leaks from your pipe systems, to secure bolts on your reactor coolant pumps, lubricate or prevent seizing of your steam turbine parts. It’s about training your expert staff how and when to use them to make sure emergencies do not occur.

Unplanned downtime is just as undesirable in the nuclear power plants as in any others, but a failure in a nuclear plant can have far reaching negative consequences which concern not only the people at the immediate location.

That’s why choosing adhesives, sealants and protective coatings for a nuclear power plant should be a precise operation where experts from both sides are closely involved. High level technical support is what comes as a package deal with the Loctite branded products. Every product recommendation comes with a training for the operational staff who will use it. You can explore options for your power plant, but please be sure to contact an expert for further selection steps.

Coal in the service of power generation

Standard

MRO Power Brochure (GLOBAL)_LR-F-2_small

Producing electricity, which we have all come to take for granted, power plants can’t really afford to stop working. Overhauling operations are carefully planned, making sure that downtime is kept to a minimum and the plant is returned to full capacity functioning quickly.

Something going wrong outside of the scheduled maintenance activities is an absolutely unwanted occurrence. There are certainly considerable differences in maintenance, depending on the type of the power plant.

I’ll be focusing on the traditional thermal, coal fired power plants in this article, but will come back to the other types as well later on. In such a power plant, there are three main maintenance areas:

  • Coal handling plant
  • Boiler maintenance
  • Ash handling

In ash handling where the biggest problems are wear and erosion, while the issues in coal handling and boiler maintenance can be defined under three common denominators: abrasion wear, vibration loosening and frequent leaks.

While the solution for renewal and protection of the metal parts can be found among the Loctite Wearing Compounds, I’ve already previously written about the repair of rubber parts such as conveyor belts. To lock threaded fasteners or seal joints and flanges on your coal crushers, gearboxes, mills and the like, select a product from the range of Loctite engineering adhesives (anaerobics). Find out more about which products best fit the applications for your coal fired power plant. For other types of power plants you can see more here.

Bonding and medicine – closer than you might think

Standard

Medical

Perhaps most people will still believe that adhesives and medicine have absolutely nothing to do with one another. And yet, there is a fair number of medical devices in whose manufacturing adhesives are used on regular basis. Needles, blood filters, catheters, IV sets, anaesthesia masks, blood oxygenators, blood pressure transducers – to name only a few.

The demands that are posed in front of this industry in terms of design are ever increasing, and the use of adhesives allows the designers much more freedom. The diversity of materials that need to be bonded together is on the rise as well, which is why serious adhesive manufacturers will partner with the manufacturers of these materials and provide bonding assessments on which their customers from the medical industry can rely without concerns.

Even though quality and reliability is the unparalleled number one priority when it comes to medical devices, manufacturing efficiency isn’t unimportant. Which is why with Loctite medical adhesives a well thought-through bonding process comes hand in hand, including dispensing, curing, in-line detection and in-line bonding speed. That’s where the key to costs saving can often be.

If the use of adhesives in food industry is highly regulated, medical industry is even more so. The new Medical Device Regulation issued this year is 360 pages long – replacing the one from 1993, which was mere 60 pages.
