打膠機工作完后中空膠固化慢的原因
打膠機打完膠后對于中空膠固化慢這個問題,根據(jù)
濟南雙組份打膠機廠家多年技術服務經驗,大多數(shù)是以下兩類原因:
According to the technical service experience of Jinan two-component gluing machine manufacturer for many years, the problem of slow curing of hollow glue after gluing is mainly caused by the following two reasons:
1、環(huán)境溫度低所造成的固化速度慢。解決方法:提高使用環(huán)境和養(yǎng)護環(huán)境溫度,如采用密閉空間設置暖房、空調升溫等方法;
1. The curing speed is slow due to low ambient temperature. Solution: improve the temperature of the use environment and the maintenance environment, such as setting a warm room in a closed space and heating the air conditioner;
2、非環(huán)境溫度低所造成的固化速度慢。解決方法:通過拉斷時間確認A、B組分的比例是否正常,在生產廠家允許調節(jié)比例范圍內可適當增大B組分的比例以加快固化速度。
2. Slow curing speed caused by low ambient temperature. Solution: confirm whether the proportion of component A and component B is normal through the breaking time, and properly increase the proportion of component B within the range allowed by the manufacturer to speed up the curing speed.
注意:
be careful:
目前市面上中空膠通常都是雙組分,雙組份膠與單組分膠在固化機理上是有明顯區(qū)別的。雙組份膠配方中已含有固化所需要的水分,不受空氣中水汽的影響,混合好后里外同時固化,可深度固化,但雙組分膠在環(huán)境溫度偏低、B組份偏少時,固化速度會變慢。
At present, the hollow rubber in the market is usually two-component, and there is a clear difference in the curing mechanism between the two-component rubber and the one-component rubber. The two-component adhesive formula already contains the moisture required for curing, which is not affected by the water vapor in the air. After mixing, the two-component adhesive can be cured at the same time inside and outside, and can be deeply cured. However, the curing speed of the two-component adhesive will be slow when the ambient temperature is low and the component B is small.
因此,打膠機打完膠后一定要注意使用和養(yǎng)護時的環(huán)境溫度以及A、B組分的混合比例,以確保固化正常。此外,一些非正常情況,如密封膠在不合理的貯存條件或者超過保質期時,或者不同廠家的中空膠混用也會出現(xiàn)固化慢的情況。
Therefore, it is necessary to pay attention to the ambient temperature during use and curing and the mixing ratio of components a and B after the gluing machine is finished to ensure normal curing. In addition, some abnormal conditions, such as unreasonable storage conditions of sealant or beyond the shelf life, or mixing of hollow adhesives from different manufacturers, may also cause slow curing.
此外如果熔膠溫度過高,如果你使用的熱熔膠粘度高(較稠),這個溫度熔出來的膠更加稠,生活經驗我們都知道,稠的東西流動性差,所以這個是有可能出現(xiàn)斷膠的情況之一。
In addition, if the melt temperature is too high, if the hot melt adhesive you use has a high viscosity (thicker), the glue melted at this temperature will be thicker. As we all know from life experience, the fluidity of thick things is poor, so this is one of the situations that may lead to glue breaking.
膠槍堵了,膠槍膠管長時間使用沒有清洗過,使得膠的積碳堵了槍口。膠的軟化點高,這個165的工作溫度熔膠慢,導致出膠速度慢。膠箱發(fā)熱管是否存在故障.這些都是廠家給出的可能導致出膠速度變慢的原因。
The rubber gun is blocked, and the rubber tube of the rubber gun has not been cleaned for a long time, which makes the carbon deposit of the rubber block the muzzle. The softening point of the glue is high, and the working temperature of 165 is slow to melt the glue, resulting in the slow speed of the glue. Whether there is a fault in the heating pipe of the rubber box. These are the reasons given by the manufacturer that may lead to the slow speed of glue delivery.
We have made clear the reasons for the slow curing of hollow glue after the glue applicator works and the relevant precautions. If you have any questions or needs, please come to our website http://dejiansw.cn Consultation and attention!
