Hay\u0131r, temelde nitril kau\u00e7uk ile EPDM ayn\u0131 m\u0131d\u0131r? Kesinlikle de\u011fil. <\/p>\n\n\n\n

Her ikisi de s\u0131zd\u0131rmazl\u0131k uygulamalar\u0131nda yayg\u0131n olarak kullan\u0131lan sentetik elastomerler olmas\u0131na ra\u011fmen, temel kimyasal yap\u0131lar\u0131 tamamen farkl\u0131d\u0131r ve bu da \u00e7e\u015fitli ortamlara kar\u015f\u0131 performanslar\u0131n\u0131 belirler. <\/p>\n\n\n\n

NBR, akrilonitril ve b\u00fctadienin bir kopolimeridir ve bu \u00f6zelli\u011finden dolay\u0131 ola\u011fan\u00fcst\u00fc ya\u011f direncine sahiptir. <\/p>\n\n\n\n

EPDM: Su ve Hava Durumu Ustas\u0131<\/h2>\n\n\n\n

EPDM, su, buhar, ozon ve hava ko\u015fullar\u0131na maruz kalma gibi uygulamalar i\u00e7in standart kau\u00e7uk haline gelmi\u015ftir. <\/p>\n\n\n\n

Ancak EPDM ve NBR tart\u0131\u015fmas\u0131ndaki en \u00f6nemli dezavantaj \u015fu: EPDM, ya\u011flar ve yak\u0131tlar taraf\u0131ndan h\u0131zla bozunur. <\/p>\n\n\n\n

NBR veya Nitril B\u00fctadien Kau\u00e7uk, tamamen farkl\u0131 bir malzemedir. <\/p>\n\n\n\n

Yak\u0131t, ya\u011flama ya\u011f\u0131 veya hidrolik s\u0131v\u0131 ta\u015f\u0131yan sistemlerdeki s\u0131zd\u0131rmazl\u0131k elemanlar\u0131n\u0131 d\u00fc\u015f\u00fcn\u00fcrken, arad\u0131\u011f\u0131n\u0131z malzeme NBR'dir. <\/p>\n\n\n\n

Bu nedenle bu uygulamalarda s\u0131kl\u0131kla EPDM yerine NBR valf yuvas\u0131 tercih edilir; nitril gerekli kimyasal direnci sa\u011flar. <\/p>\n\n\n\n

Yak\u0131t hatlar\u0131nda ve ya\u011f sistemlerinde genellikle varsay\u0131lan tercih, dayan\u0131kl\u0131 NBR oturma y\u00fczeyine sahip kelebek vanad\u0131r.<\/p>\n\n\n\n

S\u0131cakl\u0131k aral\u0131\u011f\u0131 genellikle EPDM'ye g\u00f6re biraz daha dard\u0131r ve genellikle -30 santigrat dereceden yakla\u015f\u0131k 100 veya 120 santigrat dereceye kadar iyi \u00e7al\u0131\u015f\u0131r. <\/p>\n\n\n\n

NBR'nin ya\u011f direnci ola\u011fan\u00fcst\u00fc olsa da, baz\u0131 kritik alanlarda yetersiz kalmaktad\u0131r. <\/p>\n\n\n\n

Do\u011fru elastomeri se\u00e7mek genellikle \u015fu temel soruya dayan\u0131r: S\u0131v\u0131 polar m\u0131 (su gibi) yoksa polar olmayan m\u0131 (ya\u011f gibi)? <\/p>\n\n\n\n

"Nitril mi yoksa EPDM mi daha iyi?" sorusuna tek bir cevap yok. Performans tamamen ak\u0131\u015fkan ortama ba\u011fl\u0131d\u0131r.<\/p>\n\n\n\n

Nitril kau\u00e7u\u011fun kimyasal yap\u0131s\u0131 hidrokarbonlara maruz kald\u0131\u011f\u0131nda stabildir, yani \u015fi\u015fmez veya bozulmaz. Buna kar\u015f\u0131l\u0131k, EPDM petrolle temas i\u00e7in kesinlikle uygun de\u011fildir.<\/p>\n\n\n\n

Sonu\u00e7 olarak, EPDM ve NBR tart\u0131\u015fmas\u0131nda "daha iyi" bir elastomer diye bir \u015fey yoktur; sadece i\u015fe uygun do\u011fru malzeme vard\u0131r. <\/p>\n\n\n\n
