Okwangoku, izixhobo zombhobho ezisetyenziswa kwimoto zingahlulwa zibe ngamacandelo amathathu: umbhobho wenylon, umbhobho werabha kunye nombhobho wesinyithi.Iityhubhu zenayiloni ezisetyenziswa ngokuqhelekileyo ziyi-PA6, PA11 kunye ne-PA12.Ezi mathiriyeli zintathu ngokudibeneyo zibizwa ngokuba yi-aliphatic Pa. PA6 kunye ne-PA12 ziyi-polymerization yokuvula iringi kunye ne-PA11 yi-polymerization ye-condensation.
1. Iinzuzo zeumbhobho wenayilonizezi zilandelayo: ▼ ukuxhathisa kweoli okugqwesileyo (ipetroli, idizili), i-oyile yokuthambisa kunye negrisi, kunye nokumelana neekhemikhali.▼ ukumelana nefuthe lobushushu obuphantsi: I-PA11 inokumelana nefuthe eliphantsi lobushushu - 50 ℃ kunye ne-PA12 inokumelana nefuthe eliphantsi lobushushu - 40 ℃.▼ Uluhlu olubanzi lobushushu besicelo: uluhlu lobushushu besicelo lwe-PA11 ngu-40 ~ 125 ℃, kwaye indawo ye-PA12 ngu-40 ~ 105 ℃.Emva kovavanyo lokuguga kwi-125 ℃, 1000h, 150 ℃ kunye ne-16h, umbhobho we-PA11 unempembelelo entle yokusebenza kwefuthe lobushushu obuphantsi.▼ ukumelana ne-oksijeni kunye ne-zinc ityuwa ye-corrosion: ukuchasana ne-50% isisombululo se-chloride ye-zinc ngaphezu kwe-200H.▼ ukumelana ne-asidi yebhetri kunye ne-ozone.▼ sisixhobo sokuzithambisa esinokumelana nokungcangcazela, ukuxhathisa ukunxiba, ukumelana nokudinwa kunye ne-coefficient ephantsi yokukhuhlana.▼ Ukuchasana kwe-UV kunye nokuguga kwe-atmospheric: ukuxhathisa kwe-UV yombala wendalo we-PA11 ingasetyenziselwa iminyaka eyi-2.3-7.6 ngokuxhomekeke kwimimandla eyahlukeneyo;Amandla e-anti ultraviolet e-PA11 emnyama anyuke ngokuphindwe kane emva kokongeza i-anti ultraviolet efunxayo.
Inkqubo yokwenziwa kombhobho wenayiloni yile: ① inkqubo yokukhutshwa ② ukwenza inkqubo ③ inkqubo yokuhlanganisa ④ inkqubo yokufumanisa.Nje,umbhobho wenayiloniineenzuzo ezinkulu ekusebenzeni xa kuthelekiswa nombhobho wesinyithi, ngelixa ingcono kwimichiza yokumelana nokubola kunye nokumelana nokunxiba xa kuthelekiswa nayoumbhobho wensimbi engenasici, edlala indima enkulu ekunciphiseni ubunzima besithuthi kunye neendleko zokuvelisa.
2. Zininziithumbu lerabhaizakhiwo zemoto, kunye neziseko ezisisiseko ziquka uhlobo oluqhelekileyo, uhlobo olomeleziweyo kunye nohlobo olugqunyiweyo.
Ulwakhiwo olusisiseko lombhobho werabha okwangoku, ezona zixhobo zisetyenziswa kakhulu kwimibhobho yerabha kwimarike yiFKM, NBR, Cr, CSM kunye ne-eco: ▼ ubushushu benkonzo ye-FKM (fluororubber) yi-20 ~ 250 ℃, esetyenziswa ikakhulu kwi-O- iringi, itywina yeoli, umaleko wangaphakathi weumbhobho wamafuthakunye nezinye iimveliso zokutywina.▼ ubushushu benkonzo ye-NBR (irubha ye-nitrile) yi-30 ~ 100 ℃, esetyenziselwa ikakhulu ithumbu lerabha, umsesane wokutywina kunye nokutywinwa kweoyile.▼ ubushushu benkonzo ye-Cr (irubha ye-chloroprene) yi-45 ~ 100 ℃, esetyenziselwa ikakhulu iteyiphu, ithumbu, i-wire coating, ipleyiti yerabha yegasket 'isigqubuthelo sothuli, njl. njl. ~ 120 ℃, esetyenziselwa kakhulu amatayara, iteyiphu, i-spark plug sheath, iingcingo, iindawo zombane, amakhonkco e-O, imicu yokutywina yocango kunye nefestile, njl. njl. esetyenziswa kakhulu kwiringi eshushu, i-diaphragm, i-shock pad, ithumbu lerabha, njl.
3. Njengohlobo lombhobho oqinileyo,umbhobho wesinyithiineenzuzo zobunzima obunzima, ixabiso eliphezulu kunye nokuphuka okulula.Ngoko ke, amashishini amaninzi nangaphezulu akhetha ukuyeka ukusetyenziswa kombhobho wesinyithi.Okwangoku, umbhobho we-aluminiyamu yesinyithi ufanelekile ngakumbi kwi-air conditioning system.Nangona kunjalo, amandla okuqina, ukugqabhuka koxinzelelo kunye nokumelana nokuguga kwemibhobho yentsimbi kungcono kunemibhobho yenayiloni kunye nemibhobho yerabha.
