PA malzemelerin avantajlar\u0131 ve dezavantajlar\u0131<\/span><\/h2>\n

Avantajlar<\/span><\/h3>\n

1. Y\u00fcksek mekanik mukavemet, iyi tokluk, y\u00fcksek \u00e7ekme ve bas\u0131n\u00e7 mukavemeti. \u00c7ekme mukavemeti akma mukavemetine yak\u0131nd\u0131r, ABS'nin iki kat\u0131ndan daha y\u00fcksektir.<\/p>\n

2. Ola\u011fan\u00fcst\u00fc yorulma direnci, par\u00e7alar tekrar tekrar b\u00fck\u00fcld\u00fckten sonra orijinal mekanik mukavemetini koruyabilir. Yayg\u0131n y\u00fcr\u00fcyen merdiven korkuluklar\u0131, yeni bisiklet plastik tekerlek jantlar\u0131 ve d\u00f6ng\u00fcsel yorulma etkisinin \u00e7ok belirgin oldu\u011fu di\u011fer durumlarda s\u0131kl\u0131kla PA kullan\u0131l\u0131r.<\/p>\n

Dezavantajlar<\/span><\/h3>\n

1. Suyu kolay emer<\/strong>Su emilimi, par\u00e7alar\u0131n boyutunu ve do\u011frulu\u011funu belirli bir \u00f6l\u00e7\u00fcde etkileyecektir, \u00f6zellikle ince duvarl\u0131 par\u00e7alar\u0131n kal\u0131nla\u015fmas\u0131 daha b\u00fcy\u00fck bir etkiye sahiptir; su emilimi ayr\u0131ca plasti\u011fin mekanik mukavemetini b\u00fcy\u00fck \u00f6l\u00e7\u00fcde azaltacakt\u0131r.
