膠缸中丁基膠沒有排凈即更換加入新的丁基膠。雙組份打膠機(jī)如果在膠缸中存在丁基膠的情況下退出活塞，具有優(yōu)良粘接性的丁基膠。

　　If the butyl rubber is not discharged, the new butyl rubber is replaced. If there is butyl rubber in the rubber cylinder, the piston will have good adhesive properties.

　　在膠缸底部和活塞上會(huì)形成山峰狀，而在推人新的丁基膠后，膠缸和活塞粘接的山峰狀丁基膠與新的丁基膠之間會(huì)存在大量氣泡，區(qū)別只不過是活塞處氣泡比膠缸底部氣泡少一些。因此在涂膠過程中表現(xiàn)為剛剛換膠后氣泡較大，毛刺較多，而在將近結(jié)束時(shí)，氣泡較少的現(xiàn)象。

　　At the bottom of the cylinder and the piston, the peak is formed, and after the new butyl rubber is pushed, there will be a large number of bubbles between the gums and the new butyl rubber. The difference is only that the bubbles at the piston are less than the bubbles at the bottom of the cylinder. Therefore, during the process of gelatinization, the bubbles are bigger and the burrs are more after just changing the glue, and the bubbles are less at the end.

　　成品丁基膠內(nèi)部存在氣泡。因丁基膠為半固體粘稠狀不干膠，在生產(chǎn)過程中如果混入氣泡不加以處理或處理不徹底而把氣泡存留在膠體中，在涂布過程中氣泡可隨膠體從涂膠頭排出從而影響涂布質(zhì)量。

　　There are bubbles inside the finished butyl rubber. Because butyl rubber is a semi solid sticky adhesive, the bubble can be retained in the colloid in the process of production. In the process of coating, the bubble can be discharged with the colloid from the gel head and influence the coating quality.

　　膠缸和膠頭溫度過高。由于丁基膠內(nèi)部存在大分子有機(jī)物質(zhì)，如果溫度過高，有機(jī)物質(zhì)會(huì)發(fā)生裂解，產(chǎn)生小分子物質(zhì)，其中一些在高溫下以氣態(tài)形式存在，如果此時(shí)丁基膠涂布操作，排出膠頭后，即高溫高壓狀態(tài)下的氣體突然降壓，其體積會(huì)迅速膨脹，產(chǎn)生大量微氣泡，使膠條表現(xiàn)為毛刺現(xiàn)象。

　　The temperature of the rubber cylinder and the rubber head is too high. Due to the existence of large molecular organic matter in the butyl rubber, if the temperature is too high, the organic matter will break up and produce small molecules. Some of them exist in the form of gaseous state at high temperature. If the adhesive is coated at this time, the gas will suddenly depressurization at high temperature and high pressure, and the volume will expand rapidly. The bulge produces a large number of micro bubbles, which makes the rubber strip show burr phenomenon.

　　丁基膠體直徑與膠缸直徑相差太大。如果丁基膠直徑大大小于膠缸直徑，丁基膠與膠缸內(nèi)壁存在較大空間并充斥著大量空氣，丁基膠在活塞強(qiáng)大的機(jī)械力擠壓下，膠體外壁不規(guī)則向外膨脹

　　There is too much difference between the diameter of the butyl colloid and the diameter of the cylinder. If the diameter of the butyl rubber is much smaller than the diameter of the cylinder, the inner wall of the butyl rubber and the inner wall of the cylinder is filled with a large amount of air. Under the powerful mechanical force extrusion of the butyl rubber, the outer wall of the colloid outer wall expands outwards.

　　把部分空氣擠壓封閉在膠體與缸壁之間'雖然在擠壓過程中會(huì)有部分空氣從活塞與缸壁之間的縫隙中排出，但被封閉的空氣由于丁基膠的阻礙，不能排出，導(dǎo)致在丁基膠涂布過程中間隔一定時(shí)間就會(huì)有氣泡產(chǎn)生。

　　Part of the air is squeezed between the colloid and the cylinder wall, although part of the air is discharged from the gap between the piston and the cylinder wall during the extrusion process, but the closed air can not be expelled because of the butyl rubber.
