How To Seal A Crack In Plastic
Gabriel Litke
in this video I want to show you how simple it is to reuse an old hair straightener to obtain hermetically sealed bags, all without the use of a bag sealing machine, which although it can cost little is still an extra object to use
if you have important documents or comics that you want to keep intact this is one of the best ways to keep them safe, here I also show how in case they end up in the water this is not entered and our document is safe
These plastic fillers work much in the same way as polyester fillers yet are specifically designed for the repair of plastics. Use in conjunction with your plastic welder or our XWT for the strongest repairs on tears and holes.
Leave your soldering to get hot and put the baking paper on the plastic bag you want to Seal!
Now use the Tip of welder to draw the part if you want to seal (like the photo) Be careful with this part, because the tip of welder it's really hot and you can burn your skin!
After you can test the seal with pull the two extremity of the bag
But whats happening at the plastic?
the Source of heat on the soldering melt the plastic and Link the two part of plastic together... this create a new piece of plastic and nothing can get out and nothing get in
Now the best part: The final Test for waterproof
Seal a little bit of water or another things and try to press on top of this, if you want see the liquid get out you had made a good Job
This it's a good tips when you have to reapir an important document or item you won't get wet.
Another application is for ice! You can seal the water inside and after put in the refrigerator
Stay tuned for other project, because i will post other interesting instructables and check my channel here for other special video:
Plastic pockets, such as sheet protectors, photo sleeves and card collection binder sheets, can be filled with photos, glitter, keepsakes, charms, dried flower petals, etc. If you want to seal the pocket, all you need is a glue gun. No glue. A friend of mine learned this and told me about it. I finally tried it, and it works!
Quietly, a team from The Marine Mammal Center climbed down onto the sand to help one seal in particular: a young female with a plastic strap cinched so tightly around her head it was cutting deep wounds into her blubber.
They took photos and reported her location to the Center. They recognized her from last fall, when she was photographed in October with that same strap around her head. A team tried to reach her then, but she escaped back to the ocean when she saw them coming.
Additionally, going onto the beach to rescue an entangled seal requires special permission from National Oceanic and Atmospheric Administration, the federal agency with responsibility for wildlife in national marine sanctuaries. Permission depends on a variety of factors, such as where the seals are in their annual life cycle.
On the day of, the six members of the team approached the seal from the ocean side. Two carried herding boards and shuffled the other seals away to isolate the entangled seal. The other four were directly involved in caring for the target seal.
Necklace may be difficult to identify among thousands of seals at Piedras Blancas, but the viewpoint is always open. Visitors can see her and the rest of the seals as they molt their skin in May. Friends of the Elephant Seals docents even have samples of shed skin for visitors to handle.
Teams are on call to rescue stranded mammals, as well as providing support services. Friends of the Elephant Seal docents have regular training programs so they can educate the public, as well as positions serving in the San Simeon Visitor Center.
Two-part plastic adhesives and epoxies come in tubes with plungers. These types of sealants require you to either mix the two properties before application, or prime the surface before applying the adhesive. These types of plastic adhesives are rigid, strong, and designed to adhere to hard-to-bond surfaces like PP and PE plastics.
Some plastic sealants come in single tubes, and require one step application. These plastic sealants provide a flexible seal and are intended for use with softer plastics like pool floats, umbrellas, and camping gear.
For bigger jobs that require watertight adhesion to a number of different plastics and other materials, reach for Loctite PL Marine Fast Cure Adhesive Sealant. This waterproof sealant is ideal for boats and other underwater applications. It can be used to seal out both salt water and fresh water, keeps a watertight and flexible bond, and will not shrink when cured.
For a ridged, high strength bond that is impact-resistant and will not shrink, reach for Loctite Plastic Bonder. This acrylic epoxy can be used with most plastics, but shines with PC, ABS, PVC, and much more.
The general goal here is to work with the temperatures we might see about a month before and a month after our first and last frosts. To get a useable greenhouse in the shoulder seasons.
Conceptually, the idea we settled on was to create sort of a hoop house within our greenhouse. We wanted to line the interior studs of our greenhouse with UV rated plastic, giving us the best of both worlds.
So, we started looking at various raw materials that we might be able to do what we wanted. We liked the idea of the furring strips, as it would be secure and effective, but we wanted to get the overall cost down.
It was synthetic, so it would hold up to the elements. The cording had really high tensile strength. It could easily be penetrated with a staple, meaning the cord would take the bulk of the tension instead of the plastic. Best of all, it was cheap and readily available!
We desired to have a single, contiguous piece of UV rated plastic. This would reduce overall areas where we had to join the plastic together, which create less opportunities for air exchange.
To find the center, we folded the plastic in half. And then in half again the opposite way. Similar to how you might find the center of a piece of paper without actually measuring anything.
We had pre-cut a few measured pieces of our strapping cord. We also pre-staged our staple gun with a full load of stainless steel staples. These were placed near the center of our greenhouse, where we intended to start, prior to bringing in the plastic.
With one of us under the greenhouse plastic, we found the center of the plastic. We used our orientation markers to make sure we installed the plastic relatively close to how it was intended.
The first line of strapping cord was then stapled to our greenhouse studs. We decided to do the entire top of the greenhouse first, then move down the to the sides. We have a gambrel style greenhouse, so we had two roof angles to deal with.
As we continued to attach the cording to each stud with stainless steel staples, the job became easier and easier. We no longer had to fight the plastic to move around.
So, from there, we tested heating our sealed greenhouse using a basic 1,500 watt space heater in the fall. We needed to get an idea of what might be possible before we put our plants on the line.
We set up our temperature controllers so one would kick on at a lower temperature than the other. One heater would try to maintain a minimum of 45 degrees, the second would maintain a minimum of 40 degrees.
We started putting our spring plants into the greenhouse in early April. To start with, we put out our most cold hardy plants (onions, celery, etc.) to minimize potential risk.
Due to the way it was crafted, it should be easy to tear out the cording and staples, all by hand. We can simply remove the securing mechanisms, remove the plastic and replace everything.
Also, one last thought. When we eventually resheathe our greenhouse, I am going to put plastic on the outer layer as well and then sheathe over it. (So, basically two layers of plastic.) This will make an even better airtight seal and will make it work even more effectively.
