[Medium Glass] Phenomenon 1: The butyl rubber strip coated on the aluminum spacer has a burr and is not neat. Cause: There may be impurities at the outlet of the two nozzles or the mouth of the nozzle is not smooth. Solution or suggestion: Check for impurities at the outlet of the two nozzles or whether the nozzle is smooth. Phenomenon 2: A gap (white line) appears between the butyl strip after the splicing and the second sealant. Cause: The second sealant was not properly applied. Solution: When applying the second sealant, it should be applied with force and applied in one direction to prevent air from being wrapped in the glue and reduce the sealing performance of the insulating glass. Phenomenon 3: Extrusion is not smooth after heating, and it is easy to break the glue (broken wire). Reason: The key to the use of butyl sealant is extrusion. The temperature control is very important in the extrusion process. Whether the temperature control is suitable directly affects the rheological state of the butyl sealant during the whole process, which affects the product. The aesthetics of the intrinsic quality should pay special attention to the temperature. If the temperature is too high, the sealant will melt too much, and there will be no strength or even no shape at all (flowing phenomenon); if the temperature is too low, the flow of the glue will be poor, the machine will not squeeze out the glue, which will affect the construction progress, which is the main reason for the unsuccessful extrusion. . Another reason may be that the butyl sealant is trapped in the manufacture of air bubbles and causes breakage during extrusion. Solution: The temperature is generally selected by the manufacturer's extrusion temperature, the extruder temperature, generally set the barrel between 110-140 ° C, the head is between 112-142 ° C. In order to make the host generate a certain pressure and melt the melt evenly, it is required that the temperature of the head is higher than the temperature of the barrel, and the temperature has a certain hysteresis. During the adjustment, it should be noted that the heating and cooling should be carried out gradually before the coating starts. It should be properly vented to reduce internal bubbles and voids and prevent bubbles from being generated during extrusion. Phenomenon 4: The extrusion temperature control is suitable, but the aluminum spacer and the butyl sealant have poor adhesive properties or poor adhesiveness. Reasons: 1. Aluminum spacers or conveyor belts are not clean, oily and dusty. 2. The belt is transported too fast, and the aluminum spacers are too late to be glued. 3. The aluminum frame is skewed, the glue mouth is not easy to pass or the glue position is not correct. 4. The initial viscosity of the sealant itself is poor. Solution: 1. Clean and proof the aluminum spacers and conveyor belts and adjust the speed of the conveyor belt. 2. Proportionally adjust the gap between the two nozzles. 3. When the glue is applied, the aluminum spacer should be placed vertically to prevent the aluminum spacer from sticking due to the difficulty of passing the glue nozzle or the incorrect glue position. 4. Butyl rubber is an elastic and viscous elastomer. It is extruded on a clean aluminum strip by suitable temperature and pressure. The molten butyl rubber diffuses to the surface of the adherend and gradually wets the adherend. The surface penetrates into the surface micropores. This is a physical process in which the butyl rubber is in contact with only the surface of the adherend (aluminum strip) and can only be in surface contact with the adherend after pressing. . Therefore, suitable construction pressures and temperatures facilitate the progress of this process. It is worth noting that the adsorption of the aluminum strip by the glue takes a period of time (3-5 min) to achieve a better adhesion.
