Automotive glass production line

1. Moisture curing Reacts with moisture in the air to crosslink and form an irreversible strong adhesive layer. After curing, the temperature resistance reaches 120-150℃ (far exceeding the 80℃ of EVA hot melt glue). 2. Solvent-free and environmentally friendly 100% solid content, zero VOC emissions, in line with EU REACH and FDA standards. 3. Super strong bonding Excellent adhesion to difficult-to-bond materials such as metal, plastic, wood, glass, etc. (peel strength > 15N/mm). PUR Hot Melt Glue Production Line Equipment Configuration 1. Raw material storage and metering system Storage of raw materials such as polyols, isocyanates (such as MDI/TDI), tackifying resins, additives, etc. Precise metering and delivery. Nitrogen protecting to prevent moisture absorption or oxidation, ensuring the stability of raw materials. 2. Reactor Raw materials undergo polymerization reaction in anhydrous and oxygen-free environment. Control reaction temperature and pressure to form prepolymer. Exclude water to ensure colloid stability and reaction activity. High shear mixing ensures uniform reaction without bubbles. 3. High viscosity delivery pump Stable delivery of high viscosity PUR prepolymer from the reactor to the next step. Ensure constant pipeline pressure to prevent premature solidification of materials due to stagnation. Overall closed design to prevent air and moisture from entering the system. 4. Cooling system Control the product to reach the appropriate packaging temperature before filling. Prevent the packaging material from deforming or causing degradation of active substances at high temperatures. 5. Vacuum/inert gas filling machine
