Protecting Critical Materials from Heat with Powerblanket ICE

Protecting Critical Materials from Heat

Under certain conditions and with certain materials, heat is the enemy: ruining epoxies, and interfering with the brewing process.  You can, however, protect critical materials from heat when the effects of heat are understood and proper precautions are in place.

Epoxy

Epoxy are many types of resins with similar properties and chemical structures. Typically used for adhesives, protective coatings and molds, epoxies are hard and notably inert after curing. Before curing epoxy is more fluid. The chemical reaction that results in epoxy is exothermic, meaning the reaction when epoxy is mixed creates heat. Adding more heat to this reaction makes the reaction advance faster. More heat, whether ambient temperatures or heat accelerators, will speed the chemical reaction.

In general, temperatures below 50°F/10°C are too cold for epoxy to cure properly. Temperatures around 70°F/21°C are ideal. If epoxy is kept in a container or spread in a thick layer, the heat from the reaction dissipates slower, and the heat of the chemical reaction can speed its own curing process (Legget).

Heat speeds everything about the curing process of epoxy.  If there is a need to store the epoxy, some plans for cooling must be in place.

Fermentation

protecting materials from heatHeat is an important part of the fermentation process; however, if heat enters the process at the wrong time, or lasts for too long, it can result in undesired flavors and aromas that compromise the quality of the spirit.  Spirits spend years locked inside barrels during the aging process, undergoing a series of seasonal climatic changes that trigger chemical changes. Controlling the temperature of actively fermenting wort (the sweet infusion of ground malt
or other grain before fermentation, used to produce beer and distilled malt liquors)
can have a major impact on the flavor of the finished beer. Fermenting above the normal temperature range may produce excessive fruity-flavored esters or harsh-flavored fusel alcohols (Stika).

Normal ale fermentation temperatures range from 68-72 °F/20-22 °C and lager fermentation temperatures from 45-55 °F/7-13 °C. The heat generated by an active fermentation can warm a typical 5-gallon batch of beer by 10 to 15°F/5.5 to 8.3°C (Stika).

Epoxy Curing: The Economic Approach

Epoxy curing has its challenges. Most resins for composite construction need post curing heat assistance. There are different approaches you can take for post curing temperature control. But of all the tactics and options available, there are really only two kinds: those that cost a lot of money and those that don’t.

 

Post Curing Epoxy Resins

When it comes to epoxy curing, most every epoxy resin, especially those used in composite and carbon fiber construction, has to cure and post cure at high temperatures. Normal ambient temperatures, even during hottest summer months, are never enough. Take Gold Coast Yachts for example. Gold Coast Yachts manufactures high-end, carbon-fiber yachts. Their assembly process used to involve a very expensive and time-consuming procedure for post curing the large carbon frames.

Before Gold Coast starting using Powerblanket® Curing Blankets, they had to post cure their carbon fiber structures in large ovens. But get this; they had to construct those large ovens themselves. When you have to post cure structures as large as Gold Coast does, you’re not going to find a curing oven big enough. Instead, Gold Coast had to essentially construct rooms around the carbon-fiber body, so they could then pump enough heat into the enclosed space for the post cure to set properly. If this sounds expensive and time consuming, it’s because it was.

Once Gold Coast started using our curing blankets, however, they began saving thousands of dollars and hours (even days) worth of time. We were able to customize the right size curing blankets for them to use in insulating and heating their structures for post curing perfection.

Big yachts made of carbon fiber aren’t the only large-scale dilemmas for epoxy curing. We also have several clients in the wind turbine business who use our blankets to cure the seams in those gigantic blades that go on the wind mills we all see generating so much electricity. Imagine trying to find or build an oven for one of those.

Now, the question is: what can our curing blankets do for your curing needs? Whether you have big or small parts to cure and post cure, Powerblanket curing blankets can save you the time and money associated with curing ovens. Curing ovens are expensive, and they’re limited in size and transportability. Our curing blankets, on the other hand, have no such limitation and are much, much easier on the pocket book. We have many standard sizes and we can quickly design and build custom sizes at a very reasonable cost. So when you have curing needs, look no further than here.

Grave Digging and Ground Thawing

We’re gradually approaching warmer weather now, but it’ll still be some time before the ground thaws and makes digging a lot less difficult. That’s why we’d like to introduce you to our Ground Thawing Blankets. For those in concrete, grave digging, utility maintenance, or any other digging / ground-prep-related project, Powerblanket® Ground Thawing Blankets can be a really big help.

 

image-ground-thawing-blanketsFrom Grave Digging to Concrete Prep

Whether you’re laying concrete or preparing a funeral plot, our ground thawing blankets can make the process a whole lot easier. Powerblanket Ground Thawing blankets help to thaw frozen ground prior to digging. And in the case of preparing ground for a funeral in the winter or early spring, ground-thawing assistance can make the process run a lot smoother. Here are some words from a satisfied customer who used our ground thawing blankets for their business:

“Your blankets are absolutely excellent. Thanks to Powerblanket, we were able to quickly thaw the ground and complete our job. In fact, we estimate a savings of 10 hours per site, equaling a savings of $5,000 already. Calculating this into our thousands of sites, the savings are huge! We are excited about the time and money Powerblanket has saved us and look forward to future savings.”

Our patented blend of technology and our use of durable materials enable us to deliver high watt density throughout the entire area of application, making ground thawing through electrical heat transfer safe and highly efficient. So when it comes to preparing a plot for burial, use our ground thawing blankets to make the task much easier.

 

Why Powerblanket® Ground Thawing Blankets?

  • High watt density thaws frozen ground fast
  • Quickly remove frost prior to digging
  • Melt snow and ice from ground prior to digging
  • Easily installed and removed
  • Easily transportable
  • Safe and certified to national safety standards

 

Some Things to Remember

Remember that thawing ground goes a lot faster if you first manually remove as much snow and ice as you can.  If you have a foot of snow, remove it all, then apply the blankets.  A foot of snow can add a day to the process if not removed first.

Secondly, thawing frozen ground through a layer of grass can be problematic.  The grass tends to hold the blanket up and away from the frozen ground, making the thawing process much longer than it would be with bare ground.  If a Powerblanket ground thawing blanket is left in place too long, it WILL kill the turf. So if keeping the turf healthy and intact is the goal, then don’t use a ground thawing blanket. However, if you’re trying to thaw the ground for digging purposes, then remove the grass first.

9 Things to Consider in an Epoxy Curing Solution 2Post Curing with Powerblanket Curing Blankets

Of course, after talking about the Hot Box, you may be thinking: “yeah, but what if what I need to cure is bigger than 48” x 48”? Well, there are two simple answers to this question. Depending on your application needs, we could build a custom size Hot Box for you. But if one of our flat curing blankets would work better, we would certainly suggest this as an option.

If you have curing needs that go well beyond what our Hot Boxes can handle, in regard to size and temperature, then our curing blankets are the ideal answer. Our high-temp flat blankets have high watt densities and produce higher temperatures for post curing epoxies and resins that require ranges beyond 100° F – 120° F, up to 400°F.  What’s more, these blankets can be made to cover large areas simply and effectively. So whether it’s carbon fiber construction, wind blade repair, floor coatings, or some other resin post curing application, Powerblanket has a solution for it.

Amazon Invests in Wind Power Powerblanket® Invests in Epoxy Curing

That’s right, Amazon, the online retail giant is also concerned with renewable energy. So much so that they’re investing big in new wind turbine projects in North Carolina. Now Powerblanket and Amazon have something in common, with Powerblanket investing plenty of time and resources in proper epoxy curing for the wind power industry.

 

Amazon Invests in Wind Power Powerblanket® Invests in Epoxy Curing

Amazon and Renewable Energy

In 2014, AWS (also known as Amazon Web Services) announced a respectable, and perhaps lofty, goal of running the entire organization on 100 percent renewable energy. How are they going to do so? Well, two wind-power projects in North Carolina and Indiana are a perfect start. AWS recently disclosed the fact that they have contracted with an organization known as Iberdrola Renewables to build wind turbines in a region in North Carolina. This project is expected to come to life sometime in December 2016 and will involve 208 megawatt wind turbines in Perquimans and Pasquotank counties.

This new addition to the landscape will be aptly name the Amazon Wind Farm U.S. East (that U.S. East part will be a good differentiator should Brazil ever decide to build wind turbines anywhere near the rain forest.) The reports state that this new wind farm will produce as much as 670,000 megawatt hours of wind energy per year. As a point of reference, that amount of electrical energy could power a small U.S. town for a whole year. We’re talking a town of roughly 200,000 to 300,000 residents, but the numbers are still impressive. Of course, Amazon isn’t going to be powering small towns. Instead, it will use the energy to power their AWS Cloud data centers.

In addition to this, Amazon announced another wind-farm project to undergo construction in Fowler Ridge in Benton County, Indiana. This one will generate around 500,000 megawatt hours and will come online before the Carolina project. As impressive as these projects are alone, they are still only part of Amazon’s renewable energy efforts. Word has it that the company is investing in solar energy projects too.

 

Powerblanket Also Invests in Wind Power

While we might not be supplying data centers with electrical energy harnessed by the power of wind, we are, nonetheless, vested in the industry of wind power. The construction of large wind blades involves large-scale epoxy curing that would be very costly or nearly impossible without the proper curing solution. This is why Powerblanket is proud to play a part by offering the best curing blankets around. Wind blade manufacturers use our blankets to ensure strong cure joints and fast turnaround times. Now, Powerblanket is happy to welcome Amazon to the wind-power family.

Curing Epoxy Resin On Wind Turbine Blades

Whether it’s for repair or initial construction, curing epoxy resin on wind turbine blades can be a tricky endeavor. However, with the right technology, this arduous process can be a whole lot easier.

 

Curing Epoxy Resin On Wind Turbine Blades

Wind Turbines: A Large Scale Application

The typical wind turbine blade ranges in length from 116 ft. to as much as 148 ft. That accounts for a big hunk of glass-fiber or carbon-fiber reinforced plastic. Either way you look at it, the curing process involved with such a beast is certain to take a lot of space. That’s why wind turbines are often created in pieces and then secured by joints.

Very strong, high-temperature epoxies are used for this process, but as anyone who’s worked with epoxy knows, the proper curing takes some extra heat. Can you imagine building a hot box around the joint of a turbine blade? Better yet, can you imagine having to stick that huge thing in an oven? The idea sounds ludicrous, and it is when you consider that there is a much better way of approaching the problem.

Instead of being left to the need of a hot box or an oven to properly heat cure epoxy resin on wind turbines, you could apply localized heat to the area that needs to be cured. That’s right, localized heat in the form of a revolutionary heat blanket that evenly distributes heat over the entire surface area of application. In addition to the amazing ability this blanket has of transferring heat, it also has the capability to regulate it.

By using thermostatic controllers, you can use such a blanket to cure epoxy at the ideal temperature. It’s simply a matter of setting the temperature range to the proper level for your application and then waiting for it to work its magic. With customization possibilities, this blanket is available in as many sizes as necessary, so you can cure even the largest cure joint. Shoot, you could even cure the whole blade if you want.
