ʻO ka pale ʻana o nā mea maʻamau no nā valve - NBR

Loaʻa ka NBR ma o ka emulsion polymerization o ka butadiene a me ka acrylonitrile, a ʻo ka NBR i hana nui ʻia e ka haʻahaʻa haʻahaʻa emulsion polymerization. ʻO ke kūpaʻa ʻaila maikaʻi, ke kūpaʻa ʻaʻahu kiʻekiʻe, ke kūpaʻa wela maikaʻi, ka adhesion ikaika. ʻO kona mau hemahema, ʻo ia ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, maikaʻi ʻole ozone kūʻē, maikaʻi ʻole ka hana insulation a me ka haʻahaʻa haʻahaʻa haʻahaʻa. Hoʻohana nui ʻia ʻo NBR no ka hana ʻana i nā huahana lāʻau pale ʻaila. ʻO ka NBR kahi ʻano ʻōpala synthetic i hana ʻia mai ka butadiene a me ka acrylonitrile. ʻO ia ka lāʻau synthetic me ke kūpaʻa ʻaila maikaʻi (ʻoi aku ka ʻaila alkane) a me ke kūpaʻa ʻelemakule. ʻO ka maʻiʻo Acrylonitrile (%) ma NBR he 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30 a me 18 ~ 24. ʻO ke kiʻekiʻe o ka mea o ka acrylonitrile, ʻoi aku ka maikaʻi o ka pale ʻana i ka aila, akā ʻoi aku ka haʻahaʻa o ke kū anuanu. Eia kekahi, loaʻa iā ia ka pale wai maikaʻi, ka paʻa o ka ea a me ka hoʻopili maikaʻi. Hoʻohana nui ʻia ia i ka hana ʻana i nā ʻano huahana ʻaila kūʻokoʻa, nā ʻāpana ʻaila kūpaʻa like ʻole, nā ʻeke, nā lima lima, ka paʻi paʻa, ka hose maʻalahi, ka paʻi ʻana a me ka waihoʻoluʻu ʻana i nā moena, nā mea hoʻoheheʻe kelepona, etc. ʻaila, kope a me nā ʻoihana ʻē aʻe.
