POM hot water application
ظاهرة المشكلة
POM faucets and pump housings show performance degradation and slight dimensional changes after long-term hot water use
تحليل الأسباب
Long-term use of POM in hot water has minimal effect on mechanical properties, which is its advantage as a plumbing part; but the long-term heat resistance upper limit is about 100°C, and performance decays faster under over-temperature conditions
الحل
①Select hot water parts within a long-term heat resistance of 100°C; ②evaluate copolymer grades for over-temperature conditions (long-term heat resistance is 10°C higher than homopolymer); ③perform life verification for high-temperature plumbing
الخلاصة الأساسية
POM is an excellent material for plumbing parts; the 100°C long-term heat resistance boundary and the overtaking characteristic of copolymer grades are the key points of selection; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
