Adhesive for solvent-free use generally is comprised of the adhesive of bi-component, and wherein proportion is larger is called host or A glue, and proportion is little is called fixative or B glue.This adhesive viscosity at room temperature is higher, but still has certain fluidity, and in semisolid, when carrying out compound tense, A glue and B glue carry out the proportioning mixing in proportion, are coated onto base material by applicator roll and get on.Because every kind of composite membrane has own fixing A/B glue proportioning ratio, can not the mixtures' ratio ratio between film, so the proportioning ratio of A/B glue becomes the key technology of joining adhesive process.A/B glue all needs to carry out heat treated before proportioning is mixed, and heating-up temperature is influential to the density of colloid: excess Temperature, and colloid density reduces, and in the unit interval, carries the colloid amount to reduce, and the relative proportioning ratio of A/B glue reduces; Temperature is too low, and colloid density is large, in the unit interval, carries the colloid amount to increase, and the proportioning ratio raises, the relative proportioning ratio of A/B glue raises, too high, too low, all can affect the quality of follow-up composite membrane, so A/B glue is heated in predetermined temperature, and keeps constant temperature, it is the high request of joining adhesive process.
Traditional adhesive mode of heating is to adopt to add a kind of heater at glue bucket outer bottom, and this device is by an aluminium sheet with certain thickness inner hollow, electrothermal tube, controller and be arranged in the thermal resistance composition in the glue bucket.Electrothermal tube is arranged in aluminium sheet inside.When adhesive need to heat, a default temperature value on controller, then controller sends power supply signal, and electrothermal tube starts to obtain electric heating, and the heat sent conducts to aluminium sheet, and aluminium sheet conducts heat to adhesive by barrel soleplate again.The temperature of adhesive starts to rise, and this thermal resistance is passed real time data back controller; When real time temperature reaches preset temperature, controller sends cut-offing instruction, and the electrothermal tube outage, stop heating.Because all there are the physical phenomenon of thermal inertia in electrothermal tube and aluminium sheet, they self heat can not scatter and disappear moment, so their waste heat also can conduct to adhesive, makes the adhesive temperature overheating in bucket, affect the density of adhesive, and then affect the relative proportioning ratio of A/B glue.
