- Жогорку температура каршылык: Suitable for demanding environments.
- Ар тараптуу өлчөмдөр: Includes 6 common sizes for diverse needs.
Жайгашуу
Proper preparation is essential for effective heat shrink application. Follow these steps to prepare your wires and tubing:
- Туура өлчөмдү тандаңыз: Choose a heat shrink tube that is large enough to slide over the wire or connection, but small enough to shrink down to a snug fit (considering the 3:1 shrink ratio).
- Prepare the Wires: Ensure the wires or connections to be insulated are clean, dry, and free from any debris or sharp edges that could damage the tubing.
- Түтүктү жайгаштыруу: Slide the selected heat shrink tube over the area requiring insulation. Center it evenly over the connection or exposed wire section.

Иштөө нускамалары
Once the heat shrink tubing is correctly positioned, apply heat to initiate the shrinking process. The internal adhesive will melt and create a strong, waterproof bond.
- Жылуулук колдонуу: Use a heat gun for best results. A lighter can be used for smaller tubes, but exercise caution to avoid direct flame contact which can scorch the tubing. Move the heat source evenly back and forth over the tubing.
- Observe Shrinkage: The tubing will begin to shrink rapidly, conforming tightly to the shape of the underlying wire or connection. You may see the adhesive ooze slightly from the ends, indicating a good seal.
- Ensure Even Shrinkage: Continue applying heat until the tubing has shrunk completely and evenly, with no loose spots or air bubbles. The 3:1 shrink ratio ensures a very snug fit.
- Муздатуу үчүн: Once fully shrunk, remove the heat source and allow the tubing to cool completely before handling or stressing the connection. This allows the adhesive to set.

Проблемаларды чечүү
If you encounter issues during the application of your heat shrink tubing, consider the following:
- Tubing Not Shrinking: Ensure the heat source is sufficient and applied evenly. The shrinkage temperature is 212°F (100°C).
- Uneven Shrinkage or Bubbles: This often indicates uneven heat application. Move the heat source continuously to distribute heat uniformly.
- Poor Seal or Adhesive Not Bonding: Verify that the surface of the wire/connection is clean and dry. Ensure adequate heat is applied for the adhesive to melt and flow.
- Tubing Too Loose After Shrinking: The initial size selected might be too large. Choose a smaller diameter tube that still fits over the connection before shrinking.
