現(xiàn)象一：涂敷在鋁隔條上的丁基膠條有毛邊，不整齊。

Phenomenon 1: The butyl rubber strip applied on the aluminum partition strip has rough edges and is not neat.

原因：兩膠嘴出口處可能有雜質(zhì)或膠嘴口不光滑。

Reason: There may be impurities at the outlet of the two glue nozzles or the glue nozzle mouth may not be smooth.

解決辦法或建議：檢查兩膠嘴出口處是否有雜質(zhì)或膠嘴是否光滑。

Solution or suggestion: Check if there are any impurities at the outlet of the two rubber nozzles or if the rubber nozzles are smooth.

現(xiàn)象二：合片后的丁基膠條與第二道密封膠出現(xiàn)一條間隙（白線）。

Phenomenon 2: There is a gap (white line) between the butyl adhesive strip and the second layer of sealant after lamination.

原因：第二道密封膠沒有用正確的涂敷方式。

Reason: The second sealant was not applied correctly.

解決辦法：涂敷第二道密封膠時(shí)，應(yīng)適當(dāng)用力并按一個(gè)方向涂敷，以防空氣裹入膠中，降低中空玻璃的密封性能。

Solution: When applying the second layer of sealant, appropriate force should be applied in one direction to prevent air from getting trapped in the adhesive and reducing the sealing performance of the insulating glass.

現(xiàn)象三：加熱后擠出不順利，容易斷膠（斷線）。

Phenomenon three: The extrusion is not smooth after heating, and it is easy to break the adhesive (wire).

原因：丁基密封膠使用的關(guān)鍵在于擠出，溫度的控制在擠出加工過程中至關(guān)重要，溫度控制是否適宜，直接影響丁基密封膠在整個(gè)加工過程中的流變狀態(tài)，影響著產(chǎn)品的內(nèi)在質(zhì)量的美觀，應(yīng)該對(duì)溫度特別注意。溫度過高會(huì)引起密封膠熔融過大，無(wú)強(qiáng)度甚至根本無(wú)法成型（流淌現(xiàn)象）；溫度過低，膠的流動(dòng)差，機(jī)器擠不出膠，影響施工進(jìn)度，這是擠出不順利的主要原因。另一種原因可能是丁基密封膠在制造中夾雜有氣泡，在擠出過程中造成斷膠。

Reason: The key to using butyl sealant lies in extrusion, and temperature control is crucial during the extrusion process. The suitability of temperature control directly affects the rheological state of butyl sealant throughout the entire processing, affecting the internal quality and aesthetics of the product. Therefore, special attention should be paid to temperature. Excessive temperature can cause the sealant to melt too much, lack strength, or even fail to form (flowing phenomenon); The low temperature, poor flow of the glue, and the inability of the machine to extrude the glue affect the construction progress, which is the main reason for the unsmooth extrusion. Another possible reason may be that butyl sealant contains bubbles during manufacturing, causing adhesive breakage during the extrusion process.

解決辦法：溫度的選定一般以廠家提供的擠出溫度為宜，擠出機(jī)溫度，一般設(shè)定機(jī)筒在110-140℃之間，機(jī)頭在112-142℃之間。為了使主機(jī)產(chǎn)生一定的壓力，使熔融均勻擠出，故要求機(jī)頭溫度高于機(jī)筒溫度，溫度有一定的滯后性，調(diào)整中應(yīng)注意，加溫和降溫應(yīng)逐漸進(jìn)行，涂敷膠開始前，應(yīng)適當(dāng)排氣，以減少內(nèi)部氣泡和空隙，防止擠出時(shí)產(chǎn)生氣泡造成斷膠。

Solution: The selection of temperature is generally based on the extrusion temperature provided by the manufacturer. The extruder temperature is generally set between 110-140 ℃ for the barrel and 112-142 ℃ for the head. In order to generate a certain amount of pressure on the host and ensure uniform extrusion, it is required that the temperature of the machine head is higher than the temperature of the machine barrel, with a certain degree of temperature hysteresis. During adjustment, attention should be paid to gradually heating and cooling. Before applying adhesive, appropriate exhaust should be carried out to reduce internal bubbles and gaps, and prevent bubbles from causing adhesive breakage during extrusion.
