Ukumelana Nokugqwala Kwentambo Yensimbi Engagqwaliyo Kwiindawo Eziselunxwemeni

Iindawo ezikufutshane nolwandle zaziwa ngeemeko zazo ezinzima, apho zihlala zichatshazelwa ngumoya onetyuwa, ukufuma okuphezulu, kunye nokutshiza amanzi olwandle ngamanye amaxesha. Kwiinkqubo ezikufutshane nolwandle—nokuba kubunjineli bezolwandle, uyilo lwezakhiwo zonxweme, okanye izixhobo zezibuko—intambo yocingo yentsimbi engagqwaliyoIhlala iyinto ekhethwayo ngenxa yokumelana kwayo nokugqwala ngendlela emangalisayo. Kweli nqaku, liziswe kuwe ngui-sakysteel, siza kuphonononga indlela intambo yentsimbi engagqwali esebenza ngayo kwiindawo ezikufutshane nonxweme, zeziphi izinto ezichaphazela ukumelana kwayo nokugqwala, kunye nendlela yokukhetha nokugcina imveliso efanelekileyo ukuze ihlale ixesha elide.

Kutheni Ukumelana Nokugqwala Kubalulekile Kwiindawo Eziselunxwemeni

Ukubola yinkqubo yendalo eyonakalisa isinyithi xa isabela kwizinto ezingqongileyo ezifana neoksijini, ukufuma, kunye neetyuwa. Kwimimandla eselunxwemeni, ukuxinana kweekloridi (ezivela kwityuwa yolwandle) kukhawulezisa ukubola, okukhokelela koku:

• Umthamo wentambo yocingo ophantsi wokuthwala umthwalo.

• Umngcipheko okhulayo wokungaphumeleli phantsi komthwalo.

• Ukuwohloka kobuhle, ingakumbi kwizicelo zokwakha.

• Iindleko zokulungisa eziphezulu kunye nokuphindaphinda kokutshintshwa.

Ukukhetha intambo yentsimbi engagqwaliyo efanelekileyo kunye nokusebenzisa iindlela ezifanelekileyo zokunyamekela kunceda ekunciphiseni le mingcipheko kwaye kuqinisekiswe ukhuseleko kunye nobude bexesha.

Indlela Intsimbi Engagqwaliyo Exhathisa Ngayo Ukugqwala

Intambo yentsimbi engenasici ayimelani nokugqwala ngenxa yokubaumaleko we-chromium oxide ongasebenziyoXa ibekwe kwioksijini, intsimbi engatyiwayo yenza ifilimu ye-oxide ebhityileyo, engabonakaliyo ekhusela isinyithi esingaphantsi kwizinto ezirhabaxa. Umgangatho kunye nokuzinza kwale maleko yokukhusela kuxhomekeke koku kulandelayo:

• Iumxholo we-chromium(ubuncinci i-10.5% kwintsimbi engagqwaliyo).

• Ubukho bei-molybdenum kunye ne-nickelukomeleza ukumelana nokugqwala kwemingxuma kunye nemingxuma.

Iiklasi zeNtsimbi Engagqwaliyo eziBalaseleyo kwiindawo ezikunxweme

Intsimbi Engagqwaliyo ye-AISI 316 / 316L

• Ukwakhiwa: 16-18% ye-chromium, 10-14% ye-nickel, 2-3% ye-molybdenum.

• Iingenelo: Ukumelana okugqwesileyo nokugqwala okubangelwa yikloridi kunye nokubola kwemingxuma.

• Izicelo:

  • Izixhobo zokuloba zaselwandle.

  • Iintambo zokwakha zaselunxwemeni.

  • Imigca yokubambelela.

  • Izixhobo zokuphakamisa iinqanawa kunye needokhi.

I-316L, enomxholo ophantsi wekhabhoni, inciphisa umngcipheko wokuna kwe-carbide ngexesha lokuwelda, inika ukumelana okuphezulu kokugqwala kwiindawo eziweldayo.

Intsimbi Engagqwaliyo ye-AISI 304 / 304L

• Ukwakhiwa: 18-20% i-chromium, 8-10.5% i-nickel.

• Iingenelo: Ukumelana nokugqwala kakuhle kwiimeko ezingcolisayo kancinci elunxwemeni.

• Imida: Inokutsalwa yimingxuma xa ichaphazeleka ngqo ngamanzi anetyuwa.

• Izicelo:

  • Izithintelo zonxweme (ngaphezulu kwendawo yokutshiza).

  • Iibhalustrade.

  • Izixhobo zaselwandle ezilula.

Izinto Ezichaphazela Ukumelana Nokugqwala

1. Uxinzelelo lweTyuwa

   • Okukhona i-chloride iphezulu, kokukhona umngcipheko wokubola kwemingxuma uphezulu.

2. Ubushushu

   • Iimozulu ezifudumeleyo zaselunxwemeni zinokukhawulezisa ukugqwala ngenxa yeziphumo ezikhawulezayo ze-electrochemical.

3. Inqanaba lokuvezwa

   • Intambo yocingo esetyenziswa kwiindawo zokutshiza okanye kwiindawo ezingaphantsi kwamanzi ijongene nomngcipheko ophezulu wokugqwala xa ithelekiswa nokufakelwa ngaphezulu komda wamanzi.

4. Ulondolozo

   • Intambo yentsimbi engahoywanga, nokuba yenziwe ngentsimbi engagqwaliyo, inokubola ngokukhawuleza ngenxa yeetyuwa eziqokelelweyo kunye nezinto ezingcolisayo.

Indlela Yokuphucula Ukusebenza Kwentambo Yentambo Kwiimeko Zonxweme

1. Khetha iBanga eliLungileyo

Soloko ukhethaIntambo yentsimbi engagqwaliyo engama-316 okanye engama-316Lukuze kubonakale ngqo kwiindawo zaselwandle naselunxwemeni. Kwizicelo zoyilo olukhanyayo ngaphezulu kwendawo yokutshiza, i-304 inokwanela, kodwa i-316 inika ukuthembeka okungcono kwexesha elide.

2. Sebenzisa ulwakhiwo oluchanekileyo

Ukwakhiwa kwentambo yocingo (umz., 7×19 yokuguquguquka, 1×19 yokuqina) kufuneka kuhambelane nosetyenziso ukuze kuncitshiswe ukuguguleka koomatshini okunokwaphula umaleko ongasebenziyo.

3. Faka iiCoatings eziKhuselekileyo

Nangona intsimbi engagqwaliyo imelana nokugqwala, unyango olongezelelweyo olufana neengubo zepolymer okanye ii-lubricants lunokubonelela ngokhuseleko olongezelelweyo kwiindawo ezinzima kakhulu.

4. Yenza Ulondolozo Rhoqo

• Hlamba iintambo rhoqo ngamanzi amatsha ukuze ususe iityuwa ezigciniweyo.

• Hlola iimpawu zokuqala zokugqwala, ezinje ngokutshintsha kombala okanye ukuqhekeka komphezulu.

• Phinda ufake ii-lubricants zokukhusela njengoko kucetyisiwe.

5. Liqabane naBaboneleli abaThembekileyo

Umgangatho ubalulekile. Ukufumana intambo yentsimbi engagqwaliyo kubavelisi abaziwayo abafanai-sakysteelkuqinisekisa ukuba ufumana izixhobo ezihlangabezana nomgangatho ongqongqo kunye nemigangatho yokumelana nokugqwala.

Imigangatho Efanelekileyo Kwizicelo Zonxweme

Imigangatho eliqela yamazwe ngamazwe ichaza iimfuno zokusebenza kweentambo zentsimbi engagqwaliyo kwiindawo zaselwandle nakwiindawo ezikunxweme:

• I-EN 12385: Iintambo zentsimbi zentsimbi ngeenjongo ngokubanzi — Ukhuseleko.
