What problems are prone to occur when using customized Butyl sealing tape?
[Description]Whether the temperature control is appropriate or not directly affects the rheological state of the customized Butyl sealing tape during the entire processing process. If the temperature is too high, the sealant will melt too much, lose strength or even fail to form (flow phenomenon); if the temperature is too low, the fluidity of the sealant will be poor, and the machine will not extrude the sealant, which will affect the construction progress. This is not extrusion. The main reason for success. Another reason may be air bubbles during the manufacturing process of the customized Butyl sealing tape, causing the glue to break.To get more news about Butyl Seal Tape, you can visit senpinghz.com official website.
What problems are prone to occur when using customized Butyl sealing tape? Let's learn about it together!
1. It is easy to break the glue after heating.
Reason: Whether the temperature control is appropriate or not directly affects the rheological state of the customized Butyl sealing tape in the entire processing process. If the temperature is too high, the sealant will melt too much, lose strength or even fail to form (flow phenomenon); if the temperature is too low, the fluidity of the sealant will be poor, and the machine will not extrude the sealant, which will affect the construction progress. This is not extrusion. The main reason for success. Another reason may be air bubbles during the manufacturing process of the customized Butyl sealing tape, causing the glue to break.
Solution: The temperature should be within the extrusion temperature range provided by the manufacturer. In general, the temperature of the extruder is set between 110-130°C in the barrel and 112-132°C in the head. In order to make the host produce a certain pressure and melt uniformly, the temperature of the machine head is required to be higher than the temperature of the cylinder. When adjusting the temperature, it should be noted that heating and cooling should be carried out gradually. Appropriate venting should be carried out before painting to reduce internal bubbles and voids, and prevent bubbles from causing glue breakage during the extrusion process.
2. The adhesion between customized Butyl sealing tape and aluminum spacer is not good.
Reasons: the aluminum belt or conveyor belt is dirty, oily, and dusty; the belt speed is too fast to apply glue; the aluminum frame is skewed, the glue nozzle is difficult to pass or the glue position is incorrect; the initial adhesion of the sealant itself is poor.
Solution: Clean and calibrate the aluminum spacer and the conveyor belt, adjust the speed of the conveyor belt; adjust the gap between the two glue nozzles proportionally; when coating, the aluminum frame should be placed vertically to prevent the glue nozzles from passing through or applying glue The aluminum spacers are not glued due to the incorrect position; the customized Butyl sealing tape is extruded and adsorbed on the clean aluminum strips through proper temperature and pressure, and the melted butyl glue can gradually wet the surface of the adherend and penetrate deeply into the surface. In the hole. Therefore, proper construction pressure and temperature are conducive to this process.
One of the best-selling butyl tapes from General Sealants that meets all of these criteria is the GS# WT-1-300. This sealant is able to form an instant and permanent bond to any clean and dry service, but it remains flexible even after withstanding fluctuating conditions.
This sealant is also extremely weather-resistant because it self-heals, which means bolts and fasteners won’t hinder its sealing abilities. That makes it particularly valuable for roofing applications as installation, and even reinstallation down the line, will not compromise its durability or energy efficiency.
4. Underground Utilities & Pipelines
Municipal and commercial projects require pipes to be run underground where they end up exposed to electrochemical reactions in the soil along with pressure, moisture, and temperature fluctuations. These natural changes throughout the seasons cause movement, contraction, and expansion at the joints of pipelines, which could cause leaks if not properly sealed.
The resiliency of butyl tape makes it the ideal product for protecting pipelines in extreme underground conditions. The flexibility of butyl tape means it will continue to be effective even with movement, while its unique construction makes it resistant to moisture absorption, mold, and mildew.
Ideal for this purpose is GS #79, which is a non-hardening type of butyl tape that is certified for NSF/ANSI 61 -Drinking Water System Components. Its special construction makes it suitable for any potable water application, but it’s also versatile enough to be used for construction, manufacturing, and a variety of other industries.
5. HVAC and Refrigeration Components
When it comes to creating an environmentally-friendly heating or cooling element, be it an air conditioner or a refrigerator, having a tight seal that won’t fail is crucial. GS# CT-15 hits the mark with a permanent bond and proprietary technology that minimizes and even eliminates cold flow, even under extreme pressures.
This sealant stays flexible like other butyl tapes, and it’s self-healing, which improves its efficacy. For outdoor applications, like around outlet ducts and HVAC units, it’s even weather-resistant, creating an air- and water-tight seal that keeps the interior more comfortable.
