The bonding of plexiglass plate is a very important stage in the production and processing of acrylic products. How to present the characteristics of clear and transparent acrylic, reflect the sense of value of acrylic art, maximize the level and grade of acrylic art, bonding technology here has a crucial effect.
The key to the bonding of plexiglass plate has two difficulties, one is the scope of application of adhesive itself, the other is the method of bonding. At present, there are many adhesives in the domestic and foreign sales market. There are two kinds of adhesives, one is solution type and the other is epoxy resin type. Generally speaking, epoxy type adhesives are bonded by curing, while solution type adhesives are bonded by final evaporation of organic solvent.
In addition, the bonding method is also very key, the following is a common several types of bonding processing technology, analysis of their operation process method.
Firstly, connection.
The two plexiglass panels to be connected are horizontally placed on the control service platform, together, and a adhesive tape is stuck at the bottom, leaving a gap of no more than 0.3mm wide for applying the adhesive. Use an injection needle to introduce clabon adhesive from one side of the symmetrical slow from the gap, until all filled, to be completely cured after the tape can be removed.
Secondly, building facade bonding.
Building facade bonding is one of the most common bonding techniques, which is widely used in the production of various acrylic products. The surface layer to be bonded should be cleaned and tidy first. It is best to use the mold to complete the bonding, so that the bonding does not shake, conducive to improving the quality of bonding. The thickness of the plexigenous glass plate within 3mm can be immediately used by the needle from one side of the symmetrical and slowly introduced clebond adhesive, can be bonded. Thin thickness of more than 3mm plexiglass board bonding, can pad into the fine wire, the use of capillary bonding, before the adhesive curing out of the wire, or can choose not to stick in the position of adhesive tape maintenance, with adhesive position coated with adhesive, and then tilt into the plexiglass board extrusion bubbles can be.
Thirdly, ramp bonding.
The bonding slope must have an Angle of 90 against the mold to avoid the movement of the adhesive surface. When applying Keribon adhesive, it should be symmetrical and slow. To be completely cured can be removed from the mold.
Fourthly, plane adhesion.
Planar bonding is a very unique way. The adhesive surface shall be cleaned and neat first, and placed horizontally, and the appropriate keribon goods shall be noted above. The side of another piece of plexiglas plate oblique touch is coated with adhesive acrylic, then symmetric slow learn to put down, from the side of the bubble extrusion and bonding.
