I-NBR iveliswa ikakhulu yindlela yobushushu obuphantsi be-emulsion polymerization, enokuxhathisa okugqwesileyo kwe-oyile, ukuxhathisa okuphezulu kwe-abrasion, ukumelana nobushushu obuhle kunye nokuncamathela okuqinileyo.Ukungalungi kwayo kukunganyangeki kobushushu obuphantsi, ukunganyangeki kwe-ozone, ukusebenza kakubi kokugquma, kunye nokuqina okuncinci.I-NBR isetyenziswa ikakhulu ekwenzeni iimveliso zerabha ezinganyangekiyo kwioyile, iintlobo ngeentlobo zeegaskets ezinganyangekiyo kwioyile, iigaskets, imikhono, ukupakishwa okuthambileyo, ithumbu elithambileyo, ukuprinta kunye nokudaya iirola, izixhobo zerabha yekhebula, njl. njl. kwimizi-mveliso yeemoto, inqwelomoya, i-petroleum, ukukopa kunye namanye amashishini.
I-NBR iveliswa ikakhulu yindlela ye-emulsion ye-polymerization yobushushu obuphantsi, enokumelana ne-oyile okugqwesileyo, ukumelana nokunxiba okuphezulu, ukumelana nobushushu obulungileyo kunye nokuncamathela okuqinileyo.Ukungalungi kwayo kukunganyangeki kobushushu obuphantsi, ukunganyangeki kwe-ozone, ukusebenza kakubi kokugquma, kunye nokuqina okuncinci.I-NBR isetyenziswa ikakhulu ekwenzeni iimveliso zerabha ezinganyangekiyo kwioyile, iintlobo ngeentlobo zeegaskets ezinganyangekiyo kwioyile, iigaskets, imikhono, ukupakishwa okuthambileyo, iityhubhu zerabha ezithambileyo, ukuprinta kunye nokudaya iirola, izixhobo zerabha yentambo, njl.njl. imathiriyeli kwiimoto, inqwelomoya, i-petroleum, ukukopa kunye namanye amashishini.
I-NBR inokumelana ne-oyile ebalaseleyo.I-Butadiene monoma inokudityaniswa ibe yi-copolymerized ibe ngamakhonkco amathathu ahlukeneyo: i-cis, i-trans kunye ne-1,2-焼 amaqela.Ulwakhiwo oluqhelekileyo lwe-NBR lumalunga nama-78%.Ngenxa yobukho be-cyano kwisakhiwo se-molecular chain ye-NBR, ukuxhathisa kweoli (umzekelo, kwi-oyile yamaminerali, i-fuel oils, i-oyile yezilwanyana kunye nemifuno, kunye ne-solvents) ingcono kune-rubber yendalo, i-neoprene, kunye ne-styrene-butadiene irabha.Xa kuthelekiswa nezinye iirubha, i-NBR inoluhlu olubanzi lobushushu benkonzo, ubushushu bayo bexesha elide lenkonzo yi-120oC.Ngeli xesha, i-NBR inokumelana nobushushu obuphantsi, elona qondo lobushushu lisezantsi leglasi linokufikelela kwi -55oC.
I-NBR inozinzo oluhle lweekhemikhali kunye nokusebenza kakuhle kokusebenza.Njengoko ukuxinana kwayo kunyuka kumxholo wepropylene nitrile kwisakhiwo sayo, isantya se-vulcanization siyakhawuleza kwaye ukusebenza kwamandla okuqina kuyaphuculwa, kodwa ukusebenza kokuqina kuyehla kwaye ukumelana nokubanda kuba nzima.I-NBR yirabha ye-semiconductor kuba i-cyano kwi-NBR i-polarized ngokulula ngentsimi yombane, ngoko ke ipropati ye-dielectric iyancipha.I-nBR inokwahlulwa kwiindidi ezi-5 ze-ultra-high, high, medium-high, medium and low propylene nitrile ngokwezinga lomxholo we-ACN.Indlela yokuvelisa ihlukaniswe yaba yindlela eqhubekayo kunye ne-intermittent polymerization.Indlela yepolymerization eqhubekayo idla ngokusetyenziswa kwiindidi ezimbalwa kunye nemveliso yomthamo omkhulu wemveliso kunye nosetyenziso oluphantsi.Indlela ye-polymerization engapheliyo ifanelekile kwiintlobo ezininzi kunye nemveliso encinci ye-batch, uphawu lwe-polymerization usebenzisa inani elincinci lokusetyenziswa okuphezulu kobunjineli kunye nokwakhiwa.Ukuza kuthi ga ngoku, ayiwuboni umkhwa wokutshintshana.
Nangona i-NBR ineempawu ezibalaseleyo zomzimba kunye noomatshini kunye nokusebenza kokusebenza, kodwa ixesha elide kwipetroli ene-asidi kunye nobushushu obuphezulu (150oC) kubume bendawo ayilunganga njengokusebenza kwerabha efana ne-fluorine kunye ne-propionic acid epholileyo, ngenxa yesi sizathu iinkampani zaseJamani. , Iinkampani zaseKhanada kunye neenkampani zaseJapan ukuphuhlisa ukusebenza kakuhle kwerabha ye-nitrile ye-hydrogenated (HNBR).Ukongeza, sikwaphuhlise i-NBR enokuxhathisa okuphakamileyo okubandayo kunye nokucoceka okuphezulu kunye ne-XNBR.
