Melt in a reactor, a single extruder, cooling tank 2, a traction machine.
2.2 Process approach
Hot melt adhesive formulations according to the proportion of the raw material, said bar is good, added to the autoclave. Warming to melt, stirring evenly. Then the reactor in a good rubber melt cooled to a certain temperature into the running of the extrusion machine, according to the different kinds of plastic, choose the speed of extrusion extruder. Extruder through the hot melt extrusion head squeezed into a storm-shaped extrusion hole sink, hot melt case of cooling water immediately setting, Glue stick, a cooling water tank through the first conducted a preliminary cooling setting, through the traction machine traction entered the second cooling tank, cooling tank in the second gel-like cooling will be fully
Type, Glue stick, running the sink rate of extrusion from the extruder speed control, so that the speed traction traction machine and extrusion machine extrusion speed synchronization. Adjust the control of a good extrusion speed, setting the cooling rate, the relationship between the speed traction and then cool a good Glue stick, cut into finished packing.
2.3 Glue stick performance
Melt-like variety specification is complete, diameter from φ5mm to φ20mm. Exterior color with yellow, light yellow, white, translucent, full transparency and other products. Softening point from 65 ℃ to 135t. Shear strength from 3 MPa to 8 MPa, peel strength from 50N/cm to 150 N / cm. Water absorption of less than 3% and other products.
