Ukumelana nobushushu obuphezulu be-tantalum bolts izikrufu
I-Tantalum yaziwa ngokumelana nokugqwesa kwayo okugqwesileyo, kodwa ezinye iimeko kunye nezinto zinokuyonakalisa i-tantalum. Ezinye izinto ezinokubangela i-tantalum corrosion ziquka:
1. I-alkali eyomeleleyo: I-Tantalum isengozini yokubola kwiindawo ezine-alkaline kakhulu, ngakumbi kumaqondo obushushu aphezulu.
2. I-Hydrofluoric acid: I-Tantalum ihlaselwa yi-hydrofluoric acid, ngokukodwa kwiindawo eziphezulu kunye namaqondo okushisa.
3. IiHalogens ezithile: I-Tantalum inokusabela kunye ne-halogens ethile (efana ne-fluorine kunye ne-chlorine) kumaqondo obushushu aphezulu, ebangela ukubola okunokwenzeka.
4. Iityuwa ezinyibilikisiweyo: I-Tantalum isesichengeni sokuhlaselwa ziityuwa ezithile ezinyibilikisiweyo, ngakumbi kumaqondo obushushu aphezulu.
Kuyaphawuleka ukuba kwiimeko ezininzi, i-tantalum ibonisa ukuxhathisa okugqwesileyo kwe-corrosion, iyenza ilungele ukusetyenziswa kwiindawo ezinobungozi kakhulu. Nangona kunjalo, phantsi kweemeko ezithile ezigqithisileyo ezibandakanya ezi zinto zingasentla, izilumkiso kunye noqwalaselo lunokufuneka luthatyathwe ukuqinisekisa ukuqhubeka kokuxhathisa ukonakala kwamalungu e-tantalum.

Unyango olungcono kakhulu lwe-anti-corrosion ye-bolts luxhomekeke kwisicelo esithile kunye neemeko zokusingqongileyo apho iibholiti ziya kuboniswa khona. Olu lulandelayo lunyango oluxhaphakileyo lokunqanda umhlwa:
1. Insimbi engenasici: Iibholiti zentsimbi, ngakumbi ezo zinechromium ephezulu kunye nomxholo wenickel, zinokumelana ne-corrosion. Iibholiti zensimbi ezingenasici zifanelekile kwizicelo ezininzi, ngokukodwa kwiindawo ezivezwe kumswakama kunye neekhemikhali ezithile.
2. Ukwaleka: Iingubo ezahlukeneyo zingafakwa kwiibholithi ukuqinisa ukuxhathisa kwazo. Ezi ziquka i-galvanizing, i-galvanizing kunye ne-epoxy coatings. Uhlobo ngalunye lwengubo lubonelela ngenqanaba elahlukileyo lokukhusela ukubola kwaye lunokukhethwa ngokusekelwe kwiimeko ezithile zokusingqongileyo.
3. Ii-alloys ezinganyangekiyo kwi-Corrosion: Iibholiti ezenziwe kwii-alloys ezinganyangekiyo kwi-corrosion ezifana ne-titanium, i-nickel alloys, okanye i-specialty alloys njenge-Inconel okanye i-Monel zifanelekile kwizicelo ezifuna izinga eliphezulu lokuxhathisa ukubola.
4. I-polymer coating: Iibholiti zinokugqithwa ngezinto ze-polymer ezifana ne-PTFE (Teflon) ukubonelela umqobo wokukhusela kwi-corrosion. Ezi zogquma ziluncedo ngokukodwa kwizicelo ezifuna ukuchaswa kweekhemikhali kunye neempawu ezingezizo.
5. Ukukhuselwa kweCathodic: Kwezinye iimeko, iibholiti zinokukhuselwa kwi-corrosion ngokusebenzisa iindlela zokukhusela i-cathodic, ezifana nokusetyenziswa kwe-anodes yedini okanye iinkqubo zangoku ezichukumisayo.
Xa ukhetha eyona ndlela yonyango ye-bolt anti-corrosion, kubalulekile ukuqwalasela iimeko ezithile zokusingqongileyo, izinto zebholithi, kunye neemfuno zokusebenza kwesicelo. Ukubonisana nengcali ye-corrosion okanye injineli yezinto kunokunceda ukumisela isisombululo esifanelekileyo sokuchasana nesicelo esithile.
