PPSU adhesive bonding assembly
Problem Phenomenon
PPSU bonding strength and durability; adhesive selection and treatment.
Cause Analysis
PPSU can be bonded; adhesive matching; surface treatment; curing conditions; environmental aging.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Adhesive selection; ②surface treatment; ③curing specification; ④strength testing; ⑤aging verification.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
The feasibility of PPSU bonding needs process assurance; adhesive selection and treatment are key; verification ensures long-term.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
