Waste water processing plants are something that no city, or large industrial facility like power station, pulp and paper factory or steel plant, can go without. If one went out of function, it would catch everyone’s attention very quickly and most likely lead to significant losses in downtime, penalties or health and safety issues.

One of the main materials that make parts of a waste water utility plant is concrete. Concrete is seen by most people as a very durable material, and that’s fundamentally true, but it’s far from being absolutely resistant to damages. Most usual kinds of damages that can occur on concrete are mechanical and chemical.

Waste water facilities are made of concrete and metal almost in their entirety. Both materials are prone to wear, while metal is additionally threatened by corrosion. The wear damage is caused by abrasive particles flowing through the plant or chemicals used in the pre-treatment and exploitation processes, and can happen in different parts of the facility. From influent structures through grit chambers – which are especially exposed to highly abrasive grit that can damage the pumps – to centrifuges which are the heart of any such facility.

Replacement of some of these parts is certainly an option, but nowadays there are very efficient ways not only to rebuild and repair damaged parts, but also to protect them (whether as new or after repair) and minimize the effects of future wear, increasing reliability,  extending their service life and decreasing the capital and operational expenditures.

Several waste water facilities in Hungary and Bulgaria already gave these benefits a try and were quite pleased with the results. In Hungarian case, the concrete clarifier shoulders was rebuilt and repaired using Loctite PC 7257. The processes took in average 2 days, but the facilities kept running during the repair undisturbed.

In case of the facility in Sofia, clarifier shoulders were protected from chemical damages using the product Loctite PC 7277.

Another high priority challenge of the modern waste water and water supply facilities in achieving high effectiveness, is energy consumption and equipment efficiency. Million cubic meters of water per day are transported by different types and sizes of pumps. Having in mind the total cost of pump ownership, the energy consumption in such a plant can be significant.

Using Loctite Polymer Composites for rebuilding, renewing and protecting parts subjected to wear, chemicals or weather conditions, some companies from the industry were able to achieve major equipment efficiency and energy saving improvements. Naturally, the products from this range can be used beyond the waste water processing.

Lighting article

It must be one of the things we take for granted the most: lights all around us. We’ve come to take it for granted that our days do not end with the end of the daylight and grown accustomed to just switch on a bunch of miniature (or not so miniature) surrogate suns and just keep on doing whatever we need to do, rarely wondering what it takes to produce them.

Lighting industry is among the ones subject to most increasing regulatory requirements and rising customer expectations. While the customers expect ever improving design and functionality pleasing to the eye, they will also tend to choose products with longer life span and better overall quality. For a manufacturer who wants to achieve all this, but within a reasonable costs and with acceptable impact on the environment, it’s a clear challenge.

Using adhesives and sealants in your manufacturing process can help tackle this challenge. Whether you’re in street lights or residential, industrial or architectural lighting business, there are solutions. And yes, the requirements are numerous, but so are the possibilities. Feel free to explore.

Pineapples, oceans & refrigerated containers

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?

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

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.

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

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.
