Acrylic adhesive on relevant

Acrylic adhesive is acrylic stand display rack in a critical processing step of the process, how to show the characteristics of crystal clear acrylic, reflecting the sense of the value of acrylic display rack stand, plexiglass acrylic products to maximize the quality and taste, from bonding technology the pivotal role.

Acrylic adhesive is mainly affected by two aspects, one glue itself applicability; Second bonding techniques.

There is currently a lot of glue on the domestic and foreign markets, mainly divided into two kinds, one is a two-component, such as adhesive, epoxy resins; there is a single component, such as CCl3 (chloroform). Generally, two-component adhesive is achieved by a curing reaction adhesive, single-component adhesive is a volatile solvent, and ultimately achieve bonding.

Features two-component adhesive bonding effect is better, no bubbles after bonding, not white, great strength. Disadvantage of complex operation, difficult and long curing time, slow, difficult to adapt to the requirements of mass production. The general characteristics of the one-component adhesive is faster batch production to meet the requirements of the shortcomings of the adhesive after the products easy to produce bubbles, easy white, poor weather, which directly affect the acrylic stand display rack external appearance and product quality, and therefore, in the processing of acrylic display rack stand, how to choose a suitable adhesive, improve the quality and grade of acrylic products, the bonding process is a big problem that must be addressed first.

The following is a bonding techniques:

1, butt: two pieces of acrylic panels need butt on the platform level, close, and at the bottom of a sticky tape, leaving a wide gap of not more than 0.3mm to prepare coated adhesive note. With a syringe from the cracks in the adhesive evenly from side slowly injected until all filled, to be completely cured after the tape can be thrown off.

2, facade bonding: adhesive facade is one of the most widely used bonding technology, been widely used in the production of acrylic display rack IT electronic digital products in the booth. First, the adhesive surface should be required to wipe clean. The best mode to achieve by using adhesive, the adhesive material is not shaking, help to improve the quality of bonding. 3mm thick perspex plate is adhered, the fine metal wire into the pad, the bonding is completed by capillary action, prior to curing of the adhesive drawn wire, tape or adhesive may be used, apply the adhesive bonding method .

3, the slope bonding: adhesive must be used 90o slope angle cam, sticky surface to prevent displacement. Note adhesive coating should be uniform, slowly. After curing can be completely removed by the mold.

4, surface bonding: bonding plane is a special bonding methods. First, wipe the sticky surface is clean, level and placed in the above note on the appropriate amount of adhesive. The side of the diagonal touch another piece of acrylic plate is coated adhesive acrylic board, and then even slow down, from side to complete the air bubbles out and bonding. Acrylic adhesives can be processed acrylic sheet erosion surface, and difficult to eliminate traces left behind, so you can use self-adhesive stickers with ways to protect the site without bond. Grease, dust or pores may hinder a uniform coating of the adhesive leaving bubbles. Excessive use into the air when a small amount of adhesive will bond contraction. Hair edge will direct the adhesive surface of the adhesive due to evaporation and white. Indoor humidity, temperature, etc. have a direct impact on the acrylic plate bonding.
