PTFE Poor Wear Resistance
ظاهرة المشكلة
Pure PTFE friction parts wear fast with short life; although the friction coefficient is low, the wear amount is large.
تحليل الأسباب
Although PTFE's friction coefficient is low, its wear resistance is poor; pure resin has low hardness and is easily abraded by abrasive particles; PV value (pressure × speed) exceeding limits accelerates wear; rough mating surfaces aggravate loss.
الحل
①Add reinforcing fillers such as carbon fiber and bronze powder to improve wear resistance; ②Control PV value within the design range; ③Optimize mating surface finish; ④Switch to filled modified grades when necessary.
الخلاصة الأساسية
PTFE's low friction does not equal high wear resistance; filled modification is the premise of wear-resistant applications; PV value management is a design specification.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
