Nitrile rubber inogadzirwa ne emulsion polymerization yebutadiene uye acrylonitrile.Nitrile rubber inonyanya kugadzirwa ne-low-temperature emulsion polymerization.Iyo ine yakanakisa mafuta kuramba, yakakwirira kupfeka kuramba, yakanaka kupisa kupisa uye kunamatira kwakasimba..Zvayakaipira kusamira zvakanaka kwekushisa kwakadzikama, kushomeka kweozone, kusasimba kwemagetsi, uye kuderera zvishoma.Nitrile rabha inonyanya kushandiswa mukugadzirwa kwemafuta asingaite rabha zvigadzirwa.1) Nhanganyaya Inonzi zvakare NBR.Rabha rekugadzira rinogadzirwa necopolymerization yebutadiene uye acrylonitrile.Irabha yekugadzira ine yakanaka mafuta kuramba (kunyanya alkane mafuta) uye kuramba kuchembera.Kune marudzi mashanu e acrylonitrile content (%) mu nitrile rubber: 42-46, 36-41, 31-35, 25-30, uye 18-24.Iyo yakawanda acrylonitrile yemukati, zviri nani kuramba kwemafuta, asi kutonhora kunoderera kunoderera zvinoenderana.Inogona kushandiswa kwenguva yakareba mumhepo pa120 ° C kana mumafuta pa150 ° C.Uye zvakare, ine zvakare yakanaka kudzivirira kwemvura, kusimba kwemhepo uye yakanakisa bonding performance.Inoshandiswa zvakanyanya mukugadzirwa kweakasiyana mafuta-anodzivirira erabha zvigadzirwa, akasiyana-siyana anodzivirira mafuta gaskets, gaskets, maoko, anochinjika kurongedza, akapfava hose, kudhinda uye dhaya erabha rollers, tambo dzerabha zvinhu, nezvimwewo, uye inove yakakosha mumaindasitiri akadai semotokari. , ndege, petroleum, uye kukopa elastic zvinhu.
1. Kuita Nitrile rabha inonziwo butadiene-acrylonitrile rubber, inodaidzwa seNBR, ine avhareji yehuremu hwemamorekuru hunosvika 700,000.Kunze-kuchena kusvika kuchiedza yero yakakura kana upfu hwakasimba, hukama density 0.95-1.0.Nitrile rabha ine yakanakisa kupikisa mafuta, yechipiri chete kune polysulfide rabha uye fluorine rabha, uye ine yakanakisa kupfeka kuramba uye kusimba kwemhepo.Izvo zvakashata zve nitrile rubber ndezvekuti haigoni kupikisa ozone uye inonhuhwirira, halogenated hydrocarbons, ketones uye ester solvents, saka haina kukodzera kune insulating zvinhu.Kupisa kupisa kuri nani kupfuura ye styrene-butadiene rubber uye neoprene, uye inogona kushanda pa 120 ° C kwenguva yakareba.Air tightness ndeyechipiri chete kune butyl rabha.Kuita kwe nitrile rubber kunokonzerwa nezviri mukati me acrylonitrile.Sezvo zvirimo zveacrylonitrile zvichiwedzera, kusimba kwesimba, kupisa kupisa, mafuta kuramba, kusimba kwemhepo uye kuoma kunowedzera, asi elasticity uye kutonhora kuramba kunoderera.Nitrile rabha ine kushomeka kweozone uye magetsi ekudzivirira zvivakwa, asi yakanaka kudzivirira mvura.
2 Main inoshandisa Nitrile rubber inonyanya kushandiswa kugadzira zvigadzirwa zvisingadzivirirwe nemafuta, senge pombi dzinodzivirira mafuta, matepi, madiaphragms erabha uye mabhegi makuru emafuta, nezvimwe. Inowanzoshandiswa kugadzira zvigadzirwa zvakasiyana-siyana zvinoumbwa nemafuta, seO- zvindori, zvisimbiso zvemafuta, makapu ematehwe, diaphragms, mavharuvhu, mabhero, hose yerabha, zvisimbiso, furo, nezvimwewo, zvinoshandiswawo kugadzira mashizha erabha uye zvikamu zvisingapfekere.
3 Mazano ekuvandudza mashandiro e nitrile rubber Oiri kuramba: Nekuwedzera zviri mukati me acrylonitrile, mafuta ayo anopikisa anogona kuvandudzwa, asi kutonhora kunoderera zvinoenderana.Inogona kushandiswa kwenguva yakareba mumhepo pa120 ° C kana mumafuta pa150 ° C.Uye zvakare, ine zvakare yakanaka kudzivirira kwemvura, kusimba kwemhepo uye yakanakisa bonding performance.Inoshandiswa zvakanyanya mukugadzirwa kweakasiyana mafuta-anodzivirira erabha zvigadzirwa, akasiyana-siyana anodzivirira mafuta gaskets, gaskets, maoko, anochinjika kurongedza, akapfava hose, kudhinda uye dhaya erabha rollers, tambo dzerabha zvinhu, nezvimwewo, uye inove yakakosha mumaindasitiri akadai semotokari. , ndege, petroleum, uye kukopa elastic zvinhu.Kuvandudzwa kwekudzivirira kutonhora uye kushomeka kwekushisa: Nitrile rabha haina kutonhora kutonhora, uye kutonhora kwayo kunowedzera kuwedzera nekuwedzera kweacrylonitrile.Nekushandisa nitrile rubber ine zvakasiyana-siyana zve acrylonitrile uye kugadzirisa kusanganiswa kwevanopesana-kuchembera vamiririri, vamiririri vanosimbisa uye plasticizers, inotonhora inodzivirira nitrile rubber formula ine mafuta akanaka kuramba uye kuneta kuramba inogona kuwanikwa.
