丁基胶涂布机的常见原因
Common causes of butyl rubber coater
现象1:涂在铝隔条上的丁基胶条有毛刺，不整齐。
Phenomenon 1: The butyl adhesive tape coated on the aluminum spacer strip has burrs and is irregular.
原因:两个喷嘴出口处可能有杂质或喷嘴不光滑。
Cause: There may be impurities at the outlet of two nozzles or the nozzles are not smooth.
方案或建议:检查两个喷嘴出口处是否有杂质或喷嘴是否光滑。
Solution or suggestion: Check whether there are impurities at the outlet of two nozzles or whether the nozzles are smooth.
现象2:层压后，丁基胶带和第二层密封胶之间出现间隙(白线)。
Phenomenon 2: After lamination, there is a gap (white line) between butyl tape and the second layer of sealant.
原因:第二层密封胶涂抹不正确。
Cause: The second layer of sealant is applied incorrectly.
方案:在涂抹第二层密封胶时，应使用适当的力在一个方向上涂抹密封胶，以防止空气包裹在密封胶中，降低中空玻璃的密封性能。
Solution: When applying the second layer of sealant, apply the sealant in one direction with appropriate force to prevent air from wrapping in the sealant and reduce the sealing performance of the insulating glass.
现象3:加热后挤出不顺畅，胶水容易断裂(断线)。
Phenomenon 3: The extrusion is not smooth after heating, and the glue is easy to break (broken wire).
原因:丁基密封胶应用的关键是挤出。温度控制在挤压过程中非常重要。温度控制是否恰当，直接影响密封胶在整个过程中的流变状态，影响产品内在质量的美观。应该特别注意温度。过高的温度会导致密封胶融化过多，没有强度甚根本无法形成(流动现象)；温度过低，胶水流动性差，机器无法挤出胶水，影响施工进度。这是挤压不平滑的主要原因。另一个原因可能是丁基密封胶在制造过程中混入气泡，导致挤出过程中胶水断裂。
Cause: Extrusion is the key to the application of butyl sealant. Temperature control is very important in extrusion process. Whether the temperature control is appropriate will directly affect the rheological state of the sealant in the whole process and the aesthetic appearance of the product's internal quality. Special attention should be paid to temperature. Too high temperature will lead to excessive melting of sealant, no strength or even no formation (flow phenomenon); The temperature is too low, the fluidity of glue is poor, and the machine cannot extrude glue, which affects the construction progress. This is the main reason for unsmooth extrusion. Another reason may be that butyl sealant is mixed with bubbles during manufacturing, resulting in glue fracture during extrusion.

方案:温度通常在制造商提供的挤出温度下选择。挤出机温度一般设定为机筒110-140℃，机头112-142℃。为了使主机产生一定的压力并均匀地熔融挤出，要求机头的温度高于机筒的温度，并且温度具有一定的滞后性。在调节过程中，应注意逐渐加热和冷却。在开始涂胶之前，应进行适当的排气，以减少内部气泡和空隙，并防止挤出过程中产生的气泡导致胶水断裂。
Solution: The temperature is usually selected at the extrusion temperature provided by the manufacturer. The extruder temperature is generally set as 110-140 ℃ for the barrel and 112-142 ℃ for the head. In order to make the host produce a certain pressure and uniformly melt and extrude, the temperature of the die head is required to be higher than the temperature of the barrel, and the temperature has a certain hysteresis. During the adjustment, pay attention to gradually heating and cooling. Before gluing, proper air exhaust shall be carried out to reduce internal bubbles and voids, and prevent bubbles generated during extrusion from causing glue fracture.
