stretch ceilings have long been no surprise, but not everyone knows that their production is consistent and relatively complicated process to be executed without special equipment impossible.In this case, this machine spikes suspended ceilings.
welding PVC film is produced with high frequency current - hence the name "HD machine."The instructions in this article will introduce you to the general technology soldering.
your attention will also be invited to a video on the topic: "Machine ceilings stretch."
What is HDTV machine
high-frequency welding of the film, is considered today the most qualitative way connection polihlorvinidnyh paintings.This seams to be not only sealed, but virtually invisible.
Creating durable welded joint is the main requirement for high frequency machines:
- soldering The method is as follows: rapid heating produced welded edges of the film, their merger is carried out at the molecular level.Since the heating point, the material itself is not warmed up, and thus spoil it is then impossible.
- machine for the manufacture of stretch ceiling is composed of two main elements.This welding press and the generator, the power of which should be determined by the size of joined fabrics.At the point where the spike will be produced, the material is clamped press.
- Since the electric machine, in it there are devices and components that prevent accidental damage to the material.They also provide safety equipment in general.One of them - is a device to suppress the occurrence of an electric arc, which represents a danger not only for the material but also to the electrode.
All machines are equipped with HD-magnetic lenses to suppress the noise that produce electromagnetic emissions, and interfere with other electrical appliances.In fact, the working environment carefully screened.
And, of course, impossible to do without a fuse.On power failure, the machine protects the special relay.
electrodes for welding PVC
As with any welding electrodes are also used, only a special kind.They resemble a flat metal ruler, one edge of which is clamped in the press, and the second affects the weld material.
Take a look at the photo below - it can be clearly seen, as it happens: the edges of the film are combined, and the red line shows where the seam will be held.
- Electrodes for high frequency welding are made of aluminum, brass or steel.Depending on the thickness of the fabric, they can have a different design and size.Their peculiarity is that they not only heat seam welded material passing on the press and the current pressure, but it is cooled after soldering.
- Very convenient that the fabric can be welded to the electrode positioned at any angle.This makes it possible to minimize the amount of waste material, and marriage work.By applying the fabric to the series capacitor plates (the second title of the electrode), you can get your inseam large extent.
But not every polymeric material responds well to this type of welding.The more there PVC content, the better.The minimum content in the tissue - 30%.
materials containing polyester, polyethylene and polypropylene are not suitable for high frequency welding.
process of working on the machine
itself HDTV machines in operation is quite simple and reliable.They are two types of drives: a foot or air.
They can be programmed to perform multiple operations.Adjustable as the duration of the welding process and the pressure of the press, and all this is done by the control unit.
- Automation allows you to speed up the work to create any desired size sheet, as well as dispense with the minimum number of staff - that is, one operator.With such equipment, to make the suspended ceiling with your hands is not difficult.
- this and enjoy the many private operators providing these services to the population.Acquire Machine HD for ceilings, b / y, and engaged in business.The price ceiling in this case is lower than the specialized firms, but not the fact that the quality is on the level.
In principle, the method of welding PVC film can be not only a point, but the roller.It looks like this: two rotating disk material is moved evenly, increasing pressure and temperature.
appearance of weld in this case may significantly differ, but the quality of the connection is not affected.
- There is a pressing and welding method, which is considered universal.This method can not only produce solder-joint, but also overlapping, or perform a gusset.Type weld depends on the thickness and quality of the material to be welded, and the anticipated loads during its operation.
- main load of tension ceilings is own weight fabric, which in a large square room can be quite significant.The thickness of the weld has a great influence on its mechanical strength.It should not be too thin, or, conversely, to stand out in relief.To avoid this, the electrodes must be adjusted correctly.
- way, sealed web tension not only in the case when their width is not enough for the whole room, but also to ceiling decoration.Thus, it is often carried out design, one of the options which we can see in the picture above.
In this case, the welded two kinds of cloth, differing not only in color but also the texture of the surface: one glossy, other matte.So you can make a rainbow, and checkered, and geometric design made up of triangles.
turns out very nice, the main thing - that the welding quality was excellent.
