Isitshixo sokwenza izixhobo zombhobho ezipolishiweyo ezikumgangatho wokutya sikwinyani yokuba inkqubo yokupolisha ijongana
ezona zinto zimbini zibalulekileyo ekukhuselekeni kokutya: ukukhula kweentsholongwane kunye nokucoca intsalela.
Yenza umphezulu ongaphakathi wezixhobo zombhobho ube bushelelezi kakhulu, ungashiyi ndawo yokuba iintsholongwane zizimele,
ngelixa ikwaphucula ukumelana nokugqwala ukuqinisekisa ubunyulu bolwelo.
Ukufumaneka kwesi sifakelo sepayipi kunokuqinisekiswa kwiinkalo ezine.
Thintela ukukhula kweentsholongwane ezincinci
Eyona mfuneko ibalulekileyo yokufakelwa kweepayipi ezikumgangatho wokutya kukuba udonga olungaphakathi kufuneka lube bushelelezi kakhulu,
kungekho ndawo zincinci apho ukungcola neentsholongwane zinokuqokelelana khona.
Ukugqitywa komphezulu kuphezulu kakhulu: izixhobo zombhobho ezikumgangatho wokutya zihlala zifuna uburhabaxa bodonga lwangaphakathi (iRa) obungaphantsi kwe-0.8 μm,
kwaye abo bapholisha nge-electrolytic banokufikelela kwi-Ra ≤ 0.4 μm.
Oku kuthamba okufana nesipili kwenza kube nzima ukuba iintsholongwane kunye nothuli zinamathele kwaye zikhule.
Ukususa iikona ezifileyo: Ukupolisha kunye nokuwelda okuchanekileyo kunye noqhagamshelo kususa iikona ezifileyo
kunye neengxondorha ngaphakathi kwemibhobho, nto leyo ethintela ngokwasemzimbeni intsalela yezinto.
2. Qinisekisa ukuba kulula ukuyicoca nokubulala iintsholongwane.
Umgca wemveliso yokutya ucocwa ngokungqongqo (CIP) kwaye ubulala iintsholongwane (SIP) yonke imihla,
kwaye iimpawu zomphezulu wezixhobo zombhobho zimisela ngokuthe ngqo ukusebenza kakuhle kokucoca.
Ixhasa ukucocwa kwindawo: umphezulu ogudileyo kakhulu uvumela isisombululo sokucoca ukuba sinxibelelane
kwaye uhlambe intsalela ngaphandle kwesiphazamiso, ukuqinisekisa ukuba akukho zicoci zicocayo.
Ixhasa iinkqubo zokucoca ezikwi-situde ze-CIP (ukucoca endaweni) kunye ne-SIP (ukubulala iintsholongwane endaweni).
Ithintela "ukunamathela eludongeni": ngakumbi kwiziselo ezixineneyo ezifana nobisi kunye nejusi,
ukupolisha kunokuthintela ukwakheka kokunamathela eludongeni kwezinto ngaphakathi kombhobho,
ukuphepha ungcoliseko lweemveliso zebhetshi ngenxa yexesha elide kunye nokuwohloka.
3. Ukuphucula ukusebenza kokumelana nokugqwala
Izinto ezi-asidi kunye ne-alkaline ezidibana nokutya (ezifana ne-acetic acid kunye nezinto zokucoca)
zidla ngokugqwala imibhobho. Ukwenza umaleko wokuthambisa: Ukupolisha kudla ngokwenziwa ngaxeshanye
ngeenkqubo zokuhlamba kunye nokukhupha iasidi. Oku kungenza ifilimu ye-oxide etyebileyo kwi-chromium engaphezulu kwentsimbi engagqwaliyo,
ukukhusela izixhobo zemibhobho ekungcoleni ngaloo ndlela kususa umngcipheko wokufuduka kwesinyithi esinzima kunye nongcoliseko lokutya.
Ukususa iziphene zomphezulu: Ukupholisha ngoomatshini okanye ukupholisha nge-electrolytic kunokususa imifantu emincinci,
izikali ze-oxide, kunye namasuntswana afakwe ngaphakathi (njenge-polishing paste) kumphezulu wombhobho,
ezidla ngokuba ziindawo zokuqala ukugqwala.
4. Izixhobo ezicocekileyo kunye nokuthobela imithetho
Izinto ezisisiseko ezikumgangatho wokutya: Izixhobo zombhobho ezinokusetyenziselwa ukupolisha ukutya zenziwe ngezinto ezikumgangatho wokutya ngokwazo,
ikakhulu intsimbi engagqwaliyo engama-304 okanye engama-316L, kwaye iyahlangabezana neemfuno ezisemgangathweni zesizwe zemilinganiselo yezinto zesinyithi ezifana ne-GB 9684.
Inkqubo yokuthobela imithetho: Emva kokupolisha, kufuneka basebenzise ioyile engqongqo
ukucoca ukususa amabala e-oyile aseleyo ngexesha lokucubungula kwaye kuhlolwe yi-grease analyzer ukuqinisekisa ukuba baya kuyenza loo nto.
zingangcolisi ukutya.
