很多门窗厂售后非常头疼的，不是玻璃自爆，而是交工一两年中空层开始起雾。拆开看，二道硅酮胶完好，问题几乎都出在紧贴铝条的这一圈热熔胶上——断胶、缩胶、界面有气线，水汽就是从这些微缝钻进去的。

The biggest headache for many door and window factories' after-sales service is not glass self explosion, but the fogging of the hollow layer after one or two years of delivery. Upon opening, the second layer of silicone adhesive is intact, but almost all of the problems lie in the hot melt adhesive tightly attached to the aluminum strip - breakage, shrinkage, and air lines at the interface. Water vapor has penetrated through these micro cracks.

这台负责“第一道防线”的设备，核心就管三件事：温度、压力、速度。

This device, responsible for the 'first line of defense', focuses on three things: temperature, pressure, and speed.

胶缸一般控制在 110~140℃，胶嘴要比胶缸高5~10℃，温度低了拉丝断胶，高了胶条发软塌边。

The glue cylinder is generally controlled at 110-140 ℃, and the glue nozzle should be 5-10 ℃ higher than the glue cylinder. When the temperature is low, the wire drawing will break, and when the temperature is high, the glue strip will become soft and collapse.

百万文字论坛液压压力决定出胶量，压力波动会让胶条时粗时细；皮带速度和压轮动作建议跟光电信号对齐，不然转角处容易堆胶或露白。

Hydraulic pressure determines the amount of adhesive produced, and pressure fluctuations can cause the adhesive strip to become thicker and thinner; The belt speed and roller action must be aligned with the photoelectric signal, otherwise it is easy to accumulate glue or expose white at corners.

百万文字论坛铝条建议干净无油，涂完30秒内合片，放太久表面结皮，后期会假粘脱落。

百万文字论坛The aluminum strip must be clean and oil-free. Within 30 seconds after coating, it should be laminated. If left for too long, the surface will form a crust, which may cause false adhesion and detachment in the later stage.

现场调试记三个动作就够：

Three actions are sufficient for on-site debugging:

换铝条规格先对中——铝框中心、压轮中心、双胶嘴中心三线重合，不重合就会单边不沾胶。

Align the specifications of the aluminum strip first - the center of the aluminum frame, the center of the pressure wheel, and the center of the double rubber nozzle overlap. If they do not overlap, one side will not stick to the adhesive.

首件必做破坏检查：撕开看断面是否致密黑亮，有没有气泡和白线，宽度全点≥7mm再批量跑。

百万文字论坛The first piece must undergo a destructive inspection: tear open to see if the section is dense, black, and shiny, if there are bubbles and white lines, and if the width is ≥ 7mm at all points before running in bulk.

每班停机前热态清嘴，用铜片刮嘴口（别用铁器敲），超过4小时不开机就把管路余胶顶干净，否则第二天必堵头。

百万文字论坛Before stopping each shift, clean the nozzle in a hot state and scrape the nozzle with a copper sheet (do not use an iron tool to knock). If the machine is not turned on for more than 4 hours, clean the remaining rubber on the pipeline, otherwise it will be blocked the next day.

还有一个容易忽略的坑：冷胶状态千万别推油缸退胶，固态胶会把活塞和胶缸拉伤，维修单就是这么来的。

百万文字论坛There is another easily overlooked pitfall: do not push the oil cylinder to return the glue when it is in a cold state. Solid glue can strain the piston and rubber cylinder, and that's how the repair order comes about.

把“温压速调稳、首件撕检、停机清胶”这三句钉在操作台旁边，起雾返修率通常能降一大半。

百万文字论坛Nail the three sentences of "temperature pressure speed stabilization, first piece tearing inspection, and shutdown cleaning" next to the control panel, and the fog repair rate can usually be reduced by more than half.
