Nguzogide corrosion nke ihe nkịtị maka valves - NBR

A na-enweta NBR site na emulsion polymerization nke butadiene na acrylonitrile, na NBR na-emekarị site na emulsion emulsion polymerization dị ala. Mmanya mmanu mmanu mmanu, akwa mkpuchi akwa, ezigbo nguzogide okpomoku, adhesion siri ike. Ọdịmma ya bụ nkwụsi ike dị ala na-adịghị mma, nguzogide ozone na-adịghị mma, arụ ọrụ mkpuchi na-adịghị mma yana ngbanwe dị ntakịrị. A na-ejikarị NBR eme ngwaahịa rọba na-eguzogide mmanụ.
