Izikulufu ze-tantalum bolt ezimelana nezinga lokushisa eliphezulu
I-Tantalum yaziwa ngokumelana nokugqwala okuhle kakhulu, kodwa ezinye izimo nezinto zingagqwalisa i-tantalum. Ezinye izici ezingabangela i-tantalum corrosion zihlanganisa:
1. I-alkali enamandla: I-Tantalum isengozini yokugqwala ezindaweni ezine-alkaline kakhulu, ikakhulukazi emazingeni okushisa aphezulu.
2. I-Hydrofluoric acid: I-Tantalum ihlaselwa yi-hydrofluoric acid, ikakhulukazi ekugxilweni okuphezulu namazinga okushisa.
3. Ama-Halogen athile: I-Tantalum ingasabela ngama-halogen athile (njenge-fluorine ne-chlorine) emazingeni okushisa aphezulu, okubangela ukugqwala okungenzeka.
4. Usawoti Oncibilikisiwe: I-Tantalum isengozini yokuhlaselwa usawoti othile oncibilikisiwe, ikakhulukazi emazingeni okushisa aphezulu.
Kuyaphawuleka ukuthi ezimweni eziningi, i-tantalum ibonisa ukumelana nokugqwala okuhle kakhulu, okuyenza ifanelekele ukusetshenziswa ezindaweni ezigqwalile kakhulu. Kodwa-ke, ngaphansi kwezimo ezithile ezimbi kakhulu ezibandakanya izinto ezingenhla, izinyathelo zokuphepha nokucatshangelwa kungase kudingeke kuthathwe ukuze kuqinisekiswe ukuqhubeka kokubola kwezingxenye ze-tantalum.

Ukwelashwa okungcono kakhulu kwe-anti-corrosion kuma-bolt kuncike ekusetshenzisweni okuqondile kanye nezimo zemvelo lapho amabhawodi azovezwa khona. Okulandelayo ezinye zezindlela zokwelapha ezivamile zokunqanda ukugqwala kwebhawudi:
1. Insimbi engagqwali: Amabhawodi ensimbi engagqwali, ikakhulukazi lawo ane-chromium ephezulu nokuqukethwe kwe-nickel, anokumelana nokugqwala okuhle kakhulu. Amabhothi ensimbi engagqwali afaneleka ezinhlelweni eziningi, ikakhulukazi ezindaweni ezivezwe umswakama kanye namakhemikhali athile.
2. I-Coating: Izingubo ezihlukahlukene zingasetshenziswa kuma-bolt ukuze kuthuthukiswe ukumelana nokugqwala. Lokhu kufaka i-galvanizing, i-galvanizing kanye ne-epoxy coatings. Uhlobo ngalunye lokumboza luhlinzeka ngezinga elihlukile lokuvikela ukugqwala futhi lingakhethwa ngokusekelwe ezimweni ezithile zemvelo.
3. Ama-alloy angagqwali: Amabhawodi enziwe ngama-alloy amelana nokugqwala njenge-titanium, ama-nickel alloys, noma ama-alloys akhethekile njenge-Inconel noma i-Monel alungele ukusetshenziswa okudinga izinga eliphezulu lokumelana nokugqwala.
4. I-polymer coating: Ama-bolts angahlanganiswa ngezinto ze-polymer ezifana ne-PTFE (Teflon) ukuze anikeze umgoqo wokuzivikela ngokumelene nokugqwala. Lezi zembatho ziwusizo ikakhulukazi ekusetshenzisweni okudinga ukuphikiswa kwamakhemikhali kanye nezakhiwo ezingezona izinduku.
5. Ukuvikelwa kwe-Cathodic: Kwezinye izimo, amabhawodi angavikelwa ekugqwaleni ngokusebenzisa izindlela zokuvikela i-cathodic, njengokusetshenziswa kwama-anode omhlatshelo noma amasistimu amanje ahlaba umxhwele.
Uma ukhetha indlela engcono kakhulu yokwelapha yokunqanda ukugqwala kwebhawodi, kubalulekile ukucabangela izimo ezithile zemvelo, izinto zebhawodi, kanye nezidingo zokusebenza zohlelo lokusebenza. Ukubonisana nochwepheshe bokugqwala noma unjiniyela wezinto ezisetshenziswayo kungasiza ekutholeni isisombululo esifanele kakhulu sokuqeda ukugqwala kohlelo lokusebenza oluthile.
