器具:推荐用硬壁硬底的容器和宽扁的搅拌工具(专业的搅拌机器更好)

            保证器具干燥无异物,调后尽快进行清洗(可用酒精或二甲苯进行清洗器具)

配比:AB组份胶水须按重量比进行混合,偏差建议小于5%

搅拌:胶水配比混合后,搅拌要充分均匀,保证容器的各个部位都要搅拌到位(搅胶时间没有特别限定,充分混合均交即可,所有部位色泽一致、浓度一致可定为均匀);灌封胶在搅拌后推荐抽一下真空,这样灌封出的产品外观、性能更佳。

上胶:操作时间较长的胶水在搅拌后放致几分钟在进行点胶灌封操作效果会更好;粘接或灌封的产品部位保证清洁、干燥(水下粘接胶水除外),灌封线较密或大型产品时,推荐灌封分两到三次进行,这样可以降低气泡出现的可能性。

固化:胶水点/灌好后,放于平整、通风、阴凉处让其自然固化;若要加温固化最好在点/灌后10-30分钟后放入加温为佳,加温方式最好用缓慢加温法,也可分温度段进行加温(先低温烤到初固,再高温烤)

其它:灌封类AB胶可用灌胶机、点胶机、针筒等进行操作,粘接类AB胶可用AB胶管、点胶机、针筒、塑胶袋等进行操作

Utensils: it is recommended to use containers with hard wall and hard bottom and wide and flat mixing tools (professional mixing machines are better)

Ensure that the appliance is dry and free of foreign matters, and clean it as soon as possible after mixing glue (the appliance can be cleaned with alcohol or xylene)

Proportioning: ab component glue should be mixed according to the weight ratio, and the deviation is recommended to be less than 5%

Mixing: after mixing the glue, the mixing should be fully and evenly to ensure that all parts of the container are stirred in place (there is no special limit for the mixing time, full mixing can be delivered, and all parts with the same color and concentration can be regarded as uniform); it is recommended to vacuum the potting glue after mixing, so that the appearance and performance of the potted products will be better.

Gluing: glue with longer operation time is better after mixing for a few minutes before dispensing and pouring. The bonding or sealing parts of products shall be kept clean and dry (except for underwater adhesive glue). When the pouring line is dense or large products, it is recommended to conduct pouring and sealing in two or three times, so as to reduce the possibility of bubbles.

Curing: put the glue in a flat, well ventilated and cool place for natural curing; if it needs to be heated and solidified, it is better to put it into the heating 10-30 minutes after the point / pouring. The heating method is better to use the slow heating method, or it can be heated by different temperature sections (first low temperature baking to initial setting, then high temperature baking)

Others: pouring type AB glue can be operated by pouring machine, dispensing machine and needle cylinder, while adhesive type AB glue can be operated by ab hose, dispensing machine, syringe, plastic bag, etc
