NFT Encaps closed Size 100×80 mm.
Close end caps to be kept at input end.
Fill groves with silicon and paste it on lower half of openable channels.
Using silicone sealant to attach end caps to double-layer NFT (Nutrient Film Technique) channels can be an effective way to create a watertight seal. Here’s a step-by-step guide on how to do this:
Materials you will need:
1. Silicone sealant (like the silicone 789 white).
2. Double-layer NFT channels and end caps.
3. A caulking gun.
4. A clean cloth or rag.
5. Isopropyl alcohol or a similar cleaning solution (optional)
6. A utility knife.
1. Clean the surfaces: Make sure the surfaces you will be working with are clean and free of any dirt, grease, or debris. Use isopropyl alcohol or a similar cleaning solution to thoroughly clean both the NFT channel and the end cap.
2. Prepare the silicone sealant: Load the silicone sealant cartridge into the caulking gun and cut the tip of the nozzle at a 45-degree angle. Be sure to use the appropriate silicone sealant for your specific application.
3. Apply silicone sealant: Apply a continuous bead of silicone sealant in groves of the end cap that will come into contact with the NFT channel. Make sure to apply a consistent, even layer and fill groves completely.
4. Insert the end cap: Gently press the end cap onto the NFT channel, ensuring that the silicone-sealed side of the end cap contacts the NFT channel’s lower part. Press firmly to ensure a secure bond.
5. Clean excess sealant: Wipe away any excess silicone sealant that oozes out from the joint using a clean cloth or rag. Be thorough in your cleaning.
6. Allow for curing: Silicone sealant typically takes some time to cure completely. Follow the silicon manufacturer’s instructions regarding the curing time. It’s important to avoid disturbing the joint during this time to ensure a proper seal.
7. Test for leaks: Once the silicone sealant has fully cured, conduct a leak test to ensure that the joint is watertight. You can do this by running water through the NFT channel and checking for any leaks at the end cap.
By following these steps, you should be able to effectively seal the end caps to your double-layer NFT channels, making them leak-proof. Ensure that you use a high-quality silicone sealant designed for your specific application to achieve the best results.
