Ko nga taputapu a te kaiwhakanao papua: me aro te kowhiringa papu ki te aha?Ko te aukati i te waikura o te kapiti a te hunga rawakore ki te pai o te raupapatanga e whai ake nei: 12% Cr maitai <17% Cr maitai Te waikura taumaha Te waikura Ko te waikura e pa ana ki te waikura o te rohe me te waikura i raro i te ahotea na te taunekeneke taiao.Ko nga tira Austenitic CrNi he kaha ake ki te whakapouri i roto i te reo Cl.Ki te ihirangi Cl, te pāmahana me te ahotea ka kaha ake ki te pirau.General Ko te whai ake 70 ~ 80 ℃ kahore ahotea waikura slurry papu kaihanga.Mehua ki te aukati i te waikura ahotea he tiketike Ni ihirangi (Ni> 25% ~ 30%) Cr ˉ Ni austenitic mangai maitai Kowiri tira slurry kaihanga papu.
Te waikura me te kakahu E pa ana ki te wai tere-tere i runga i te mata whakarewa te waikura.Rerekē te wai abrasive horo waikura me te kakahu na te reo kei roto.He rereke te waikura o nga mea rereke me te aukati mau.Te parenga abrasion ki te waikura na te rereketanga o te hurihanga pai: ferritic austenitic – ferritic steel < austenitic steels .
Te waikura Cavitation Ka puta te Cavitation ina kiia te papu he cavitation erosion na te waikura.Aukati i te waikura cavitation o te tikanga tino mahi me te ngawari ko te cavitation.He maha nga wa ka puta i te wa e whakahaere ana i te papu cavitation, hei karo i te waikura o te cavitation, ka taea te whakamahi i nga rauemi cavitation-resistant,kaihanga papu slurrykoura, parahi ūkuikui, he kowiri tira, 12% te maitai chromium.Inaa, ko te kino o te waikura he maha nga hua o te whakakotahitanga o nga momo waikura, ki te whakatōpū i te take whiriwhiri.Tuarua, ko nga mea whakarewa o te papu me nga tikanga whiriwhiri 1 Rauemi .`
He maha nga rauemi papu.Ko nga mea whakarewa noa he rino, he rino whakarewa, he 12% nga tira chromium, he kowiri tira austenitic 316L konumohe kowiri me etahi atu.I tua atu i reira he rauemi rino maka silicon tiketike mo te pāpāho ha'iriiri , № Re ⒍ st, Monel , B, Hastelloy C, 904, CD4MCu, titanium , titanium alloy.
Common matū hanganga o te rauemi koranu ko te papu noa ki te awhina rauemi kore-whakarewa: Teflon , rapa nitrile, rapa chloroprene, rapa fluorine, rapa waihanga, i roto i te tua FFKM , graphite, muka karaihe ki tonu PTFE me te rite.
