雙組份打膠機(jī)更常見問題的處理方法
雙組份打膠機(jī)作為中空玻璃設(shè)備中常常運(yùn)用的產(chǎn)品，在購買低或者二手的設(shè)備有時(shí)會(huì)呈現(xiàn)一些問題，針對這些問題該是如何處理的呢?
As a product often used in insulating glass equipment, two-component gluing machine sometimes presents some problems when purchasing low-cost or second-hand equipment. How to deal with these problems?
Analysis of the treatment of the most common problems of the two-component gluing machine -- non sticking
1、事前是否按標(biāo)準(zhǔn)做相容性測驗(yàn)
1. Is the compatibility test conducted according to the standard in advance
2、維護(hù)時(shí)間短就進(jìn)行剝離性粘結(jié)測驗(yàn)，維護(hù)溫度較低(尤其在冬天)
2. Peel bond test for short maintenance time, low maintenance temperature (especially in winter)
3、中空玻璃打膠機(jī)泵的氣壓缺乏，導(dǎo)致膠混合不勻，粘結(jié)作用要差些，同時(shí)容易形成槍頭壓力缺乏，打的膠縫不細(xì)密(密實(shí)度不行)
3. Due to the lack of air pressure in the pump of the insulating glass gluing machine, the glue mixing is uneven, and the bonding effect is poor. At the same time, it is easy to form a lack of gun head pressure, and the glue seam is not fine (the density is not good)
4、設(shè)備故障問題，導(dǎo)致膠混合作用欠安。假如打膠機(jī)的氣缸密封墊磨損的時(shí)分，就會(huì)導(dǎo)致不一致的固化劑混合入膠內(nèi)，AB泵工作行程不同步或者不匹配，AB組分混合不均勻，呈現(xiàn)花膠情況。有些在剛打完膠時(shí)還查看不出來，等膠干透了，就會(huì)透過玻璃看到花膠?？蛇x用接連擠出測驗(yàn)來判斷一下，即在一張平板上來回打出一條蛇形的密封膠，時(shí)間維持在三到五分鐘，讓泵少運(yùn)轉(zhuǎn)2個(gè)周期，查看是否存在異常情況(即所謂的軟點(diǎn))。
4. Equipment failure, resulting in the rubber mixing function is not safe. If the cylinder gasket of the glue machine is worn, it will lead to inconsistent curing agent mixed into the glue, the working stroke of AB pump is not synchronous or mismatched, and ab components are not mixed evenly, showing the situation of flower glue. Some of them can't be seen when the glue is just finished. When the glue is dry, you will see the flower glue through the glass. Continuous extrusion test can be selected to judge, that is, a snake shaped sealant is punched back and forth on a flat plate for three to five minutes, and the pump is allowed to run for at least two cycles to check whether there are abnormal conditions (i.e., the so-called soft spot).
5、雙組份打膠機(jī)不同廠家的AB膠混用
5. Mixing of AB glue from different manufacturers
6、溶劑不符合要求，或未干透等。特別需求留意的一點(diǎn)是膠在維護(hù)的階段，膠的固化和膠的粘結(jié)性建立是獨(dú)立的，就是說就是膠到達(dá)徹底固化，并不意味著膠和基材建立了徹底的粘結(jié)性。尤其對雙組份來說特別顯著。因而，玻璃單元接受應(yīng)力前要答應(yīng)有滿足的時(shí)間來建立粘結(jié)性，這一點(diǎn)非常重要。
6. The solvent does not meet the requirements or is not dry. Special attention should be paid to the fact that during the maintenance stage, the curing of the adhesive and the establishment of the adhesion of the adhesive are independent, that is to say, the complete curing of the adhesive does not mean that the adhesive and the substrate have established a thorough adhesion. Especially for two components. Therefore, it is very important to allow a sufficient time to establish the adhesion of the glass unit before accepting the stress.
