China Izikhonkwane zokumelana nobushushu obuphezulu tantalum izikrufu Umenzi kunye noMboneleli

Ukumelana nobushushu obuphezulu be-tantalum bolts izikrufu

Izikhonkwane zokumelana nobushushu obuphezulu tantalum izikhonkwane Umfanekiso obonakalayo

Inkcazelo emfutshane:

Iibholiti zeTantalum kunye nezikrufu ziqhele ukusetyenziswa kwiqondo lobushushu obuphezulu kunye neendawo ezidliwayo ngenxa yokumelana nokugqwesa kwayo okugqwesileyo kunye nokukwazi ukugcina iimpawu zoomatshini kumaqondo obushushu aphezulu.

Yintoni enokugqwesa i-tantalum?

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.

Yeyiphi eyona anti corrosion ingcono yeebholiti?

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 zensimbi ezingenasici, ngakumbi ezo zinechromium ephezulu kunye nomxholo we-nickel, zikwazi ukumelana nokugqwala. 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.
