Pure acrylic light transmittance of up to 95%, with crystal-like quality, so many acrylic products are treated and treasured as crystal products. How to show the clear and transparent characteristics of acrylic, reflect the value of acrylic crafts, maximize the grade and taste of acrylic crafts, bonding technology plays a decisive role here.
The bonding process of acrylic sheets is mainly affected by two aspects:
1. Applicability of the adhesive itself.
2. Bonding operation skills.
There are many kinds of adhesives in the domestic and foreign markets, mainly in two types, one is two-component, such as universal adhesive, epoxy resin; and the other is one-component. Generally, the two-component adhesive is bonded by a curing reaction, and the one-component adhesive is a final volatilization of a solvent to achieve bonding. The two-component adhesive is characterized by good bonding effect, no bubbles after bonding, no whitening, and high strength. The disadvantages are complicated operation, high difficulty, long curing time, slow speed, and difficulty in adapting to mass production. The general one-component adhesive is characterized by high speed and can meet the process requirements of mass production. The disadvantage is that the bonded product is easy to generate bubbles, easy to be white, and has poor weather resistance, thereby directly affecting the outer part of the acrylic product. In terms of aesthetics and product quality.
Therefore, in the processing of acrylic products, how to choose a suitable adhesive to improve the grade and grade of acrylic products is a big problem that must be solved first in the bonding process.
