Ungakuthuthukisa kanjani ukumelana nokushisa kwenjoloba?

Ukumelana nokuguga komoya okushisayo noma ukuguga okushisa kuya ngokuya kubaluleke kakhulu, ikakhulukazi ezingcemeni zezimoto lapho izingxenye zenjoloba zisetshenziswa kakhulu ezikhaleni ezimboziwe ezinamazinga okushisa aphezulu anamazinga aphezulu. Abakhiqizi bezimoto baye bazizwa bekhula kakhulu ngokuzitholela ukuze bakwazi ukuthola insizakalo ende izingxenye zabo zenjoloba. Izakhiwo zokushisa ukushisa kwe-anaerobic nokushisa nezindawo zokuguga komoya zihlukile. Irabha linokumelana nokushisa okungcono, kepha kungenzeka ukuthi alikamelana nokuhlaselwa komoya-mpilo.

Qaphela: Lezi zimiso zokuhlola ezijwayelekile kungenzeka zingasebenzi ecaleni ngalinye elithile. Noma iyiphi enye yezinto eziguquguqukayo ezingathuthukisa ukumelana nokuguga noma ukuguga kokuguga nakanjani kuzothinta ezinye izakhiwo, kungaba ngcono noma kubi.

1. I-Pumpluoroorolastomer

Uma impahla yerabha idingeka ukuba ibe nokumelana kahle nokushisa okuhle kakhulu, kufanele ukhethe irabha ephelele. Kubikwa ukuthi izinga lokushisa elisetshenzisiwe lasePurfuoroolastomer lifinyelela ku-316 ℃.

2, irabha le-fluorine

I-Fluorine Rubber FKM inokumelana kahle nokushisa okuhle kakhulu, futhi ingasetshenziswa emazingeni okushisa afinyelela ku-260 ℃. Ukuze uphinde uqinise ukumelana okuphezulu kwerabha le-fluorine yerabha, udinga ukukhetha ukwamukelwa okulungile kwe-acid (i-acid accesbent), i-calcium oxide, njll. Ngokukhetha iBisphenol af njengohlelo lokuvuselela, ukumelana nokushisa kwenjoloba kuzoba ngcono. Isetshenziswa emvelweni kawoyela ye-Hush Injini, ukumelana nokushisa kokushisa kwe-ternary fluorooelastomer eyenziwe ngeVinylidene Fluoride, iTetrafluoroethylene ne-Phylene ingcono kune-fluorooloromer ejwayelekile. Lokhu kungenxa yokufakwa esikhundleni kwe-hexafluoropropylene nge-propelene kwinqubo ye-polymerization.

3, HNBR

Lapho kukhuphuka izinga le-hydrogenation, okungcono ukumelana nokushisa kwe-HNBR, ngoba cishe asikho isibopho esiphindwe kabili esingesihle ku-Cantenate Chain engazinzile. Amanye ama-HNBR asakwazi ukuvota nge-sulfur ngoba asenezibopho ezithile ezingalawulwa kabili. Kodwa-ke, uma uvikezelwe nge-peroxide, ukumelana nokushisa kwengxenye kuzothuthukiswa. Nge-HNBR Rubber, iTotm inganikeza ukumelana okungcono kokushisa kune-dop ngenxa yokuguquguquka okuphansi kanye nesisindo esiphakeme samangqamuzana sala makhisi e-trioctyl.

4. Neoprene

Uhlobo lwe-W-Neoprene lunokuvimbela okungcono kokushisa okufudumele kune-G-Type neoprene. I-Diphenyyamic Octanoate iyi-antioxidant engcono ye-neoprene, engathuthukisa ngempumelelo ukumelana nokushisa.

I-5, EPDM

I-EPDM isazoba nokumelana nokushisa okuhle ngo-125 ℃ ngemuva kokufanele. Ukusetshenziswa kwe-Peroxide Vulcanized Eppdm, kungenza irabha linokumelana okungcono kokushisa.

I-6, i-viscor ephansi ye-viscor yendlela ye-EPDM

Okuqukethwe okuphezulu kwe-ethylene kanye ne-viscor yesigaba se-Ultra-esiphansi se-ELTRA.

7, Gwema ukusebenzisa i-High Styrene Resin

Gwema ukungeza i-styrene resin ephezulu kurabha esetshenziswe ekushiseni okuphezulu.

I-8, i-talcum powder

Ku-epdm hose irabha, buyisela i-40% yekhabhoni emnyama nge-talcum powder, engathuthukisa ukumelana nokushisa kokushisa kwenjoloba. Amanye amamaki we-talcum powder anezinzuzo ezivelele ukwedlula ubumba oluphathisiwe noma olungalashwa kulokhu.

9, Isimo sePlosini Esiphezulu Esiphezulu

Phakathi kwamapulasitiki, ama-viscositizers aphezulu anamandla anganikeza ukumelana okungcono kokushisa okungcono kunesiphikiso esiphansi sokubona. Ngoba ipulasitiki ephezulu yePlosipizi inesisindo esiphakeme se-molecular, hhayi kulula ukuyisebenzisa, ngaleyo ndlela ukuqina okuhle nokuphikiswa okuhle kokushisa.

I-10, uwoyela wembewu wokudlwengula we-neoprene

Ukuze wenze i-Neoprene ibe nokuqina okungcono, i-oyili ye-canola iyadingeka ngoba inokubona okuphansi, okwenza irabha libe ne-hyteresis eliphansi kanye nokuguquguquka okuphansi, okungenza irabha libe nokumelana nokuguga okuhle.

11, ngempumelelo i-EV / Semi-Isebenza nge-Sev Bulcanization System

Ohlelweni olusebenzayo noma olusebenzayo lwe-Vulcanization, isilinganiso se-accelerator kanye nesibabule siphezulu, okungukuthi, 'Ukuphakanyiswa okuphezulu kanye nesibabule se-sulfur Isistimu, isilinganiso se-Sulfur Bond eyodwa kanye ne-subfur bond ephindwe kabili kune-sulfur bond, ngakho-ke, ukuqina kokuphikiswa kokushisa kwerabha kuyathuthuka futhi ukumelana nokushisa kokushisa kuyathuthuka.

12, Zinc oxide

I-Vulcanization / Sub-Sulfuramide System yerabha, egcwele i-zinc oxide eningi, inganikeza irabha elingcono lokuguga ukushisa kanye nokuphikiswa okungcono ku-post-sulfur.

13, i-peroxide vulcanized irabha le-EPDM

E-Peroxide Vulcanized I-EPDM Compound, iZMTI ikhethwe njenge-antioxidant, enganikeza i-modulus ephakeme ye-modulus kanye nokuvimbela ukushisa.
