I-GB/T6614 ZTA2 Titanium TA2 Ivalve Yebhola Elintantayo
I-Titanium ball valve iyi-valve yebhola eyenziwe nge-titanium ehlanzekile noma i-titanium alloy. I-Titanium inokumelana nokugqwala okuqinile ngenxa yamavalvu ensimbi asebenza kakhulu ngamakhemikhali. I-Titanium isabela nomoya-mpilo ukuze yakhe ifilimu ye-passive oxide eqinile endaweni yayo. Ifilimu ye-oxide ku-valve yebhola le-titanium izinzile futhi kunzima ukuyincibilika. Ngisho noma ilimele, inqobo nje uma kunomoya-mpilo owanele, ingakwazi ukuzilungisa futhi ivuselele ngokushesha.

IZIMPAHLA KA-TA2
Izici zekhemikhali: I-Titanium inomsebenzi wamakhemikhali aphezulu futhi ingasebenza ngezinto eziningi. Emazingeni okushisa aphezulu, ingasabela ne-carbon monoxide, i-carbon dioxide, umhwamuko wamanzi, i-ammonia, nezinhlanganisela eziningi zezinto eziphilayo eziguquguqukayo. I-Titanium ihlangana namagesi athile, ingagcini nje ngokwakha inhlanganisela phezulu, kodwa futhi ingena ku-lettice yensimbi ukuze yakhe izixazululo eziqinile ze-interstitial. Ngaphandle kwe-hydrogen, zonke izinqubo zokusabela azihlehliseki.
Izici ze-Antioxidant: Uma i-titanium ishiswa endaweni yomoya ezingeni lokushisa elivamile lokusebenza, yakha ifilimu ye-oxide ezacile kakhulu, eminyene, futhi ezinzile. Inomphumela wokuvikela futhi ingavimbela i-oksijini ukuthi ingasakazeki ensimbi ngaphandle kwe-oxidation eyengeziwe; Ngakho-ke, i-titanium izinzile emoyeni ngaphansi kuka-500 ° C. Ngaphansi kuka-538 ℃, i-oxidation ye-titanium ilandela iphethini ye-parabolic. Lapho izinga lokushisa lingaphezu kuka-800 ℃, ifilimu ye-oxide iyabola bese ama-athomu omoya-mpilo angena ku-lattice yensimbi nefilimu ye-oxide njengongqimba oluguqukayo, okwandisa okuqukethwe komoyampilo we-titanium futhi kuqiniswe ifilimu ye-oxide. Ngalesi sikhathi, ifilimu ye-oxide ayinawo umphumela wokuvikela futhi izoba brittle.
Forging: Izinga lokushisa lokushisisa lokuvula ingot lingu-1000-1050 ℃, kanti ukuwohloka ngakunye kokushisa kulawulwa ku-40-50%. Izinga lokushisa lokushisa lokubumba okungenalutho liyi-900-950 ℃, futhi ukuguqulwa kulawulwa ngaphakathi kwe-30-40%. Izinga lokushisa lokushisisa le-die forging kufanele libe phakathi kuka-900 no-950 ℃, futhi izinga lokushisa lokugcina lokubumba akufanele libe ngaphansi kuka-650 ℃. Ukuze kuzuzwe usayizi odingekayo wezingxenye eziqediwe, izinga lokushisa lokushisa eliphindaphindiwe elilandelayo akufanele lidlule ku-815 ℃, noma cishe libe ngaphansi kuno-β Izinga lokushisa lokushintsha lingu-95 ℃ m.
Ukusakaza: Lapho kusakazwa i-titanium emsulwa yezimboni, ama-ingots ensimbi noma amabha akhubazekile ancibilikisiwe esithandweni se-arc esisetshenziswayo se-electrode angasetshenziswa njengama-electrode asebenzisekayo, futhi afakwe esithandweni se-arc se-vacuum esetshenziswayo. Isikhunta sokuphonsa singaba uhlobo lokucubungula i-graphite, uhlobo lokucindezela i-graphite, kanye nohlobo lwegobolondo lokutshala imali.
Ukusebenza kwe-Welding: I-titanium yezimboni ifanele ukushisela okuhlukahlukene. Ijoyinti eshiselwe inezici ezinhle kakhulu zokugeleza futhi inamandla afanayo, ipulasitiki, nokumelana nokugqwala njengento eyisisekelo.

Izinhlelo zokusebenza
I-TA2 isesigabeni esisodwa α Uma iqhathaniswa ne-titanium emsulwa yezimboni, inezinzuzo zokuminyana okuphansi, indawo encibilika kakhulu, ukumelana nokugqwala okuqinile, izakhiwo ezinhle zokukhanda kanye nokuvumelana kwe-biocompatibility, futhi isetshenziswa kabanzi ku-aerospace, ukwakhiwa kwemikhumbi, nezinkambu ze-biomedical.
