Intsimbi engagqwaliyo yinto emangalisayo edlala indima ebalulekileyo kumashishini ahlukeneyo, ngenxa yeempawu zayo ezizodwa kunye nokusebenza kwayo okungenakuthelekiswa nanto. Kodwa ngaba ubusazi ukuba kukho imfihlo efihliweyo yokugcina ukusebenza kwayo kunye nobude bayo? Le mfihlo ikwinkqubo eyaziwa ngokuba yi-passivation.

Intshayelelo kwiNtsimbi Engagqwaliyo

Ukuqonda amandla okungasebenzisi kuqala ngokuqaphela iziseko zentsimbi engagqwaliyo ngokwayo. Intsimbi engagqwaliyo ayisiyonto ilula nje;

yingxubevange eyenziwe ngentsimbi, ikhabhoni, kunye nedosi enkulu ye-chromium.

Yintoni Eyenza Intsimbi Engagqwaliyo Ibe Yeyodwa

Isidlali esiphambili kwibali lentsimbi engatyiwayo yi-chromium. Xa ichaphazeleka yioksijini, i-chromium yenza umaleko omncinci nongabonakaliyo we-chromium.

i-oxide kumphezulu wentsimbi. Olu maleko alusebenzi, oko kuthetha ukuba alusebenzi nakweyiphi na enye into.

1. Ukuqonda ukuxhathisa ukugqwala

I-Chromium oxide yingelosi ekhusela intsimbi engagqwaliyo. Ithintela ukugqwala nokugqwala, eziziingxaki eziqhelekileyo kwezinye izinyithi.

Oku kuxhathisa ukugqwala kwenza intsimbi engagqwaliyo igama layo kunye nokusetyenziswa kwayo ngokubanzi.

2. Indima yokudlulisa i-Passivation kwi-Stainless Steel

Ngoku, masingene kwisihloko esiphambili - i-passivation. I-passivation yinkqubo yeekhemikhali ephucula umaleko we-chromium oxide owenzeka ngokwendalo.

Oku kwenza intsimbi imelane ngakumbi nokugqwala nokugqwala.

3. Isayensi Ebangela Ukungabi Namdla

Ngexesha lokungasebenzi, intsimbi engagqwaliyo iphathwa ngesisombululo se-asidi ethambileyo. Oku kususa intsimbi ekhululekileyo kunye nezinye izinto ezingcolisayo kumphezulu,

nto leyo enokuphazamisa ukwakheka komaleko we-chromium oxide.

Ungathanda ukwazi ukuba kutheni intsimbi engagqwaliyo kufuneka ingasebenzi?

Ekuqaleni, kufuneka sazi ukuba ithetha ukuthini intsimbi engatyiwayo nengenasici? Ukungatyiwa kwentsimbi engatyiwayo kubhekisa ekwenzeni umphezulu wentsimbi engatyiwayo uphendule ngearhente yokungatyiwa ukuze kwenziwe ifilimu yokungatyiwa ezinzileyo ekhusela isiseko sentsimbi engatyiwayo ekugqwaleni okubangelwa yi-oxidation kunye nokugqwala. Ukusebenza kwentsimbi engatyiwayo kulunge kakhulu. Nangona kunjalo, kwiindawo ezikunxweme okanye xa zidibene neekhemikhali ze-asidi kunye ne-alkali, ii-ion ze-chloride eziveliswayo zinokungena ngokulula kwifilimu engatyiwayo yentsimbi engatyiwayo. Intsimbi engatyiwayo iya kugqwala kancinci kancinci kwaye igqwale ngokuhamba kwexesha. Ke ngoko, intsimbi engatyiwayo kufuneka igqwale. Intsimbi engatyiwayo egqwalisiweyo inokuphucula isiseko sokuqala sokungatyiwa kwengqwala ngeminyaka emi-3-8, inciphise kakhulu amathuba okugqwala kwentsimbi engatyiwayo.

Isihluzo se-HENGKO sentsimbi engagqwaliyo esifakwe kwi-sintered steel sinobukhulu obuchanekileyo be-air pore, ubungakanani bomngxuma wesihluzo esifanayo kunye nokusasazwa okufanayo; ukungena komoya okuhle, ukujikeleza komoya okukhawulezayo, isiphumo esihle sokubanjwa, ukusebenza kakuhle kokuhluza; ukumelana nokugqwala okuhle, ukumelana nobushushu obuphezulu, ukumelana nokutshayiswa bubushushu, izinto zentsimbi engagqwali zingasebenza kubushushu obuphezulu; ubude betyhubhu yesihluzo esincinci bunokufikelela kwi-800mm, ubungakanani obukhulu besakhiwo sepleyiti yesihluzo bunokufikelela kwi-800mm ubude * 450mm ububanzi, kwaye ububanzi obukhulu besakhiwo sesihluzo esijikelezayo bunokufikelela kwi-450mm. Sikwabonelela ngokudlulisa iindawo zemveliso, Ukuba ufuna ukufaka kwindawo engqongqo yokuxhathisa ukugqwala kunye nokuxhathisa ukugqwala.

Iingenelo zePassivation

Kukho iingenelo ezininzi zokusebenzisa intsimbi engagqwaliyo, zonke ezi negalelo ekusebenzeni kwayo ngcono kwaye ihlale ixesha elide.

Ungayenza njani intsimbi engatyiwayo ye-passivation?Masikuxelele.

Ngenxa yokuba iintlobo ezahlukeneyo zentsimbi engagqwaliyo zisebenzisa imixube eyahlukeneyo yeekhemikhali zokuthambisa, ezinye iinkcukacha ziya kwahluka ngexesha lenkqubo yokuthambisa yentsimbi engagqwaliyo. Ukuthambisa kufuneka kwenziwe ngokwezifiso. Nangona kunjalo, inkqubo esisiseko idla ngokuba namanyathelo afanayo: Qinisekisa ukuba umphezulu wenxalenye ucocekile. Kuphela xa isiseko siveziwe apho inokuthi ithambise ngcono. Beka inxalenye enye okanye ezininzi eziza kuhanjiswa kwisitya. Galela ulwelo lwekhemikhali kwisitya kwaye uvumele iindawo zimanzi kangangexesha elithile. Hlamba ngamanzi abalekayo. Qinisekisa ukuba umphezulu wenxalenye ucocekile kwaye ungenalo ulwelo lokuthambisa oluseleyo.

Ukudluliselwa kwe-asidi ye-nitricyenye yezona teknoloji zisisiseko zangoku zokudlulisa amandla. Ngaphambi kokukhetha iteknoloji yokudlulisa amandla, kufuneka sazi isisombululo seekhemikhali esifunekayo kwimpendulo yokudlulisa amandla yentsimbi engagqwali ukuze siphephe ukusebenzisa isisombululo esingalunganga ukubangela umonakalo kwiindawo ezithile. Kwaye kwangaxeshanye sikhetha iteknoloji yokudlulisa amandla enxulumeneyo ngokwempawu zentsimbi engagqwali eyahlukileyo. Umzekelo, umxholo we-chromium wentsimbi engagqwali ye-austenitic (njengentsimbi engagqwali ye-304) uhlala uphezulu kunowentsimbi engagqwali ye-martensitic (njengentsimbi engagqwali ye-430), okwenza ii-alloys ze-austenitic zikwazi ukumelana nokugqwala kunye nokubola.

Ngaphambi kokuba kufakwe iindawo zentsimbi engagqwaliyo, kufuneka kuqwalaselwe la manqaku alandelayo:

Ii-Weldments zisenokungafaneleki xa zisetyenziswa kwi-passivation. Ifilimu engashukumiyo kumphezulu wentsimbi engatyiwayo yenza ukuba ikwazi ukumelana nokugqwala. I-Arc welding iya kwenza ukuba izinto zikwazi ukumelana nobushushu obuphezulu, ngaloo ndlela zitshabalalise ukumelana nokugqwala.

Kufuneka ibhafu yamakhemikhali eyenzelwe wena. Ubushushu kunye nohlobo lwe-asidi esetyenziswa kwinkqubo yokudlulisa kufuneka zilungiswe ngokwendlela i-alloy esetyenziswa ngayo. Oku kongeza iindleko kunye nobunzima xa kuthelekiswa ne-electropolishing. Ezinye ii-alloy azinakusetyenziswa. Umzekelo, ezinye ii-alloy zentsimbi engagqwaliyo ezinomxholo ophantsi we-chromium kunye ne-nickel ziya kutshatyalaliswa. Ke ngoko, azinakusetyenziswa.

Eyona nzuzo iphambili yokusetyenziswa kwe-stainless steel passivation kukuba inokuphucula ukumelana nokugqwala kweendawo zentsimbi engagqwaliyo, kwaye ixabiso liphantsi kunelo lokusetyenziswa kwe-electropolishing. Eyona ngxaki inkulu yenkqubo yokusetyenziswa kwe-electropolishing kukuba ibiza kakhulu kunenkqubo eqhelekileyo yokusetyenziswa kwe-passivation. Ukongeza, ukusetyenziswa kwe-electropolishing akunampembelelo ibalulekileyo kumaleko we-oxide okhuselayo wentsimbi efana nokusetyenziswa kwe-passivation.

Nangona kunjalo, xa kuthethwa ngemeko yomphezulu weendawo, eyona nto iphambili ekufuneka yenziwe, ukupholisha nge-electropolishing kuseyindlela ekhethwayo. Ukupholisha nge-electropolishing akufani nokupholisha nge-electropolishing ukwenza umphezulu wenxalenye ube mpuluswa, kodwa akutshintshi kakhulu imbonakalo yenxalenye. Ke ngoko, ukupholisha nge-passivation akuyondlela ifanelekileyo ukuba imveliso ifuna umphezulu ogudileyo nonganamatheliyo. Amashishini okutya kunye namayeza adla ngokusebenzisa iindawo zentsimbi engagqwaliyo ezipholishwe nge-electro-polished kuba umphezulu uthambile kwaye kulula ukuwucoca nokubulala iintsholongwane.
