Acryklic chemical name is also called PMMA polymethylmethacrylate or inferior strength,derived from English organic glass(organic glass),is a kind of development early important plasticity of polyme -r materials,has good transparency,chemical stability and weather resistance,easy dyeing,easy process -ing,nice appearance,has been widely used in the handicraft industry.Pure acrlic transmittance up to 95%,with the same crystal quality,so many acrylic products are treated as crystal products to treat and treasure.How to show the clear and transparent characteristics of acrylic,reflect the value of acrylic han -dicrafts,maximize the quality and taste of acrylic handicrafts,adhesive technology plays a decisive role here.
The bonding process of acrylic plates is mainly affected by two aspects:
1.Applicability of the adhesive itself.
2.Operation skills of adhesion.
There are many adhesives in the market at home and abroad,there are two main types,one is a two -component,such as universal adhesive,epoxy resin;and then there's a single component.In general,tw -o-component adhesive is through the curing reaction to achieve bonding,single-component adhesiv -e is the final volatile solvent and achieve bonding.The characteristics of two-component adhesive are good bonding effect,no bubble,no whitening,high strength.Disavantages are complex operation,diffic ulty,long curing time,slow speed,difficult to adapt to the requirement of mass production.And the cha -racteristics of the general single component adhesive is fast,can meet the process requirements of ba -tch production,the disadvantage is that after the bonding of the product easy to product bubbles,whi -t,poor weather resistance,which directly affects the appearance of acrylic products quality.
Accordingly,in the processing of yakeli product,how to choose appropriate adhesive,raise the grad -e of yakeli product and class,it is a big problem that must solve above all in sticking technology.
