How to properly seat the heat shrinkable tubing with different tools

In previous articles we have already met with you with heat-shrinkable tubing and learned the main types and characteristics of this products, and in this article we will talk about how to properly seat the heat shrinkable tubing and how at the same time the tool is better use.

The heat shrinkage can be heated

There are several options when heating using different types of heat-shrinkable tube.

The most readily available, but the embodiment is controversial shrinking treatment by conventional cigarette lighters or matches.

For small diameter tubes Lighter yet somehow and fit, but if you need to process thicker Shrink, the lighter (or matches) to do this, of course, possible, but at the same time compression of a tube shape is not quite flavorful.

If the use of a lighter is not possible, some masters are trying to adapt to these goals, conventional hair dryer drying. But the desired temperature for high-quality shrink he is not able to create.

Note. Normal shrinkage temperature may range from 90 to 160 degrees Celsius. Temperature is entirely dependent on the grade of the shrink tube.

A conventional dryer may provide about 70 degrees temperature and then immediately near the nozzle. The use of special nozzles narrowly focused, of course, be able to help with the shrinkage of small diameter tubes, but their use greatly reduces the life of the dryer.

And with thick high-temperature shrinkage of conventional dryer generally can not do anything.

As a result, this can happen with a low-quality compound nedozhatymi cavities in which moisture may penetrate. So it is advisable to use a specialized tool.

Tools for working with heat shrink

At the moment, there are only five kinds of tools, namely:

1. Building a high-temperature dryer.

2. Mobile butane gas burners.

3. Gas soldering irons.

4. Burner propane.

5. Radiant burner.

At the same time industrial dryer just ideal for thin-walled tubes. A variety of the nozzle and the possibility of temperature control greatly simplifies the job.

The disadvantages of the dryer construction is the fact that it requires a mains voltage of 220 V.

And at the beginning of the shrinking process itself have to hold the phone to the hot air flow is not blown away from its location.

Infrared burner without drawbacks building dryer, and heating is very fast.

Note. Please note this feature black tube, it heats up much faster than with color counterparts. Do not forget about this feature, otherwise you can easily burn through the tube.

When using gas burners consider such a time that the shrinkage should be carried out so-called "soft" flame. Understand that the flame for shrinkage can be as follows: in the flame should contain language yellow.

This requirement also applies to gas burners.

But propane burner - is the perfect option for high-quality heating and shrinkage of thick-walled tubes.

Important. When using any of the above listed instruments following algorithm should be observed for shrinking: when warming up, always make rotationally translational movement and do not stay in one place, as can burn tube.

Tool selection depends on the following factors:

- wall thickness.

- Size of the tube.

- Material.

Rules shrink tubing installation

1. If your handset has a considerable length, the warm-up process should begin with its center, and then move to the edge. Such heating will save you from the formation of air bubbles and gaps. In this case, haste can bring to a marriage. First, treat the circle center and only then proceed to further warming

2. Remember, not only shrinking shrinks in diameter, but also along the entire length, so when choosing a heat shrink tubing necessarily pretends stock.

Important. When choosing a stock, note that when the insulation materials with different diameters on height difference also takes a certain length of the product.

In addition, if you are unsure of the correct pick stocks, then warm up the tube is not in the middle, and start with the edges. Such a method reduces the longitudinal contraction of the length.

If you need to insulate any bare metal, pre-heat the metal itself. Thus, you get rid of the so-called "cold scars." This requirement applies more to the heat shrink tubing with thick walls.

If you need to shorten the pipe, then use in this case, a pair of scissors. After the cut edges should be as smooth and does not have cracks or burrs. Only in this way will not tear and shrinkage of the most densely lay down on the product.

Also, if you need to insulate the junction of wires and tubing is not long enough, you should not stretch the tube.

You certainly close the compound itself, but due to the fact that the handset itself is thinned, reduced mechanical and electrical strength, which is not desirable in all cases.

Also, do not try to expand the tube Round, this can lead to the fact that shrinking burst at the most inopportune moment.

That's all I wanted to tell you about the correct shrinking heat shrink tubing.

Thank you for your attention!
