Termoshayby for fixing polycarbonate. How to strengthen? Instructions

The wide use of polycarbonate in various areas has become possible due to the unique characteristics and aesthetic data of this material. When installing products from polycarbonate, it is necessary to take into account some features of this material. In order to maintain the performance of the panels, it is necessary to select the fasteners correctly. How to choose the right thermocouples for fixing polycarbonate, and also how to carry out the installation, this article will tell.

Properties and distinctive qualities of polymer plastics

1. The material has high strength and requires the processing of high-quality tools.
2. Termoshayby for fixing polycarbonate should be resistant to corrosion.
3. When working with plastic, it is necessary to take into account its high coefficient of thermal expansion. Hard fixation can cause a frost in the rupture of the blade, and in the heat, swelling.
4. The fastening elements should not degrade the appearance of the structure.

Fasteners

The optimal option when installing a structure of polycarbonate is the use of thermowells, which help to solve the following tasks:

• Strong and reliable fixation of the web to the supporting structure;
• Sealing of holes drilled in polycarbonate for the installation of washers, which prevents dust, liquid and cold from entering the structure;
• Polycarbonate and the material from which the thermowells are made, expand and contract at the same time;
• Color assortment makes it possible to select fasteners in the color of the design itself.

What are the thermowells used for fixing polycarbonate?

The material for manufacturing is:

• Stainless steel (service life is unlimited);
• Polypropylene (service life - 3-4 years);
• Polycarbonate (will serve up to 20 years).

Termoshayba for fastening polycarbonate from stainless steel are used for fastening large-sized and in areas with strong winds on metal supporting structures. The fastening element has a circular shape with a small depression in the middle and a hole in the center. The seal is made of polyurethane into the recess. For a secure attachment, the distance between the washers is 25-30 cm.

Today, the fasteners on which the plastic washer are in great demand. Although polypropylene fasteners are exposed to ultraviolet radiation, which destroys the material for several years. As a result, the canvas starts to vibrate and can collapse. The advantages include low cost, aesthetic appearance and a wide range of colors. Produced and transparent products.

The most popular are universal thermocouples made of polycarbonate, especially when installing transparent sheets. Such fastening elements:

• Durable due to special treatment from ultraviolet radiation;
• Harmoniously combined with the main material and almost invisible;
• Do not collapse and do not change their physical properties under temperature changes;
• Due to the fact that the washer is flat, it is sealed to the sheet, without damaging it.

Manufacturers produce thermowells with a leg (selected for a specific thickness of the sheet) and without a leg (are universal).

The thermoshow consists of:

• The puck itself with or without a foot;
• Sealant (polymer ring);
• Covers (washer copper or plastic);
• (Usually sold separately).

Polycarbonate fastening rules

1. When drilling holes for thermowells in plastic and the supporting structure, the tool is installed strictly perpendicular. Drilled even at a small angle hole will cause a breach of tightness and crease of the panel.
2. Only sharp drills are used, it is better with a central fixation (a drill is suitable for wood), which will not slip and damage the canvas.
3. The hole for the thermowell is made a couple of millimeters more than the thickness of the self-tapping foot, taking into account the possible deformation of the plastic under the influence of heat.
4. Use only stainless steel screws with a cap.
5. During installation, the seal should be firmly pressed against the polycarbonate surface, but not pressed.
6. The distance between the thermowells is between 25 and 70 cm, depending on the size of the structure and the operating conditions.

Which heat seal is better: with a foot or universal?

Many believe that due to the element such as the stem of the thermowell, more reliable sealing is achieved, the chance to "squeeze" the sheet by the screwdriver (prevents the resting leg) decreases and the risk of "leaks" decreases. It should be remembered that polycarbonate and thermowells are usually available in different places, therefore tolerances for sheet thickness and plastic may vary by about 1 mm. Due to this, there may be conditions for leakage in all attachment points.

Experts advise that when using universal thermowells slightly "clamp" fasteners. In the cold, "clamping" is compensated for by reducing the thickness of the polycarbonate sheet.
