Brass
Kushandiswa kwendarira nemhangura kwakatangira mazana emakore, uye nhasi kuri kushandiswa mune mamwe emazuva ano matekinoroji uye maapplication achiri kushandiswa mamwe echinyakare maapplication akadai sezviridzwa zvemumhanzi, ziso rendarira, zvinyorwa zvekushongedza uye tepi nemasuo hardware.
Brass Yakagadzirwa Nechii?
Brass ialloy yakagadzirwa kubva musanganiswa wemhangura uye zinc kugadzira zvinhu zvine huwandu hwakasiyana hwekushandisa huinjiniya. Brass kuumbwa kunopa simbi kunyungudika kwakakodzera kune akawanda maapplication, kusanganisira akakodzera kujoinha uchishandisa brazing maitiro. Kunyunguduka kwendarira kwakadzikira pane mhangura kunosvika 920 ~ 970 madhigirii celsius zvichienderana nehuwandu hwekuwedzera kweZn. Brass inonyungudika yakadzikira pane iya yemhangura nekuda kweiyo Zn yakawedzerwa. Brass alloys inogona kusiana mukuumbwa kweZn kubva padiki se5% (inonyanya kunzi Gilding Metals) kusvika pamusoro pe40% sekushandiswa mumachining brasses. Izwi risingawanzo shandiswa ibhuronzi, uko kunoshandiswa kumwe kuwedzera kwerata.
Brass inoshandiswa nei?
Brass kuumbwa uye kuwedzerwa kwezingi kune mhangura kunosimudza simba uye kunopa huwandu hwemaitiro, izvo zvinoita kuti mabhurashi ave akasiyana-siyana emhando yezvinhu. Iwo anoshandiswa kune simba rawo, corrosion resistance, chitarisiko uye ruvara, uye nyore kushanda nekubatana. Chikamu chimwe chete che alpha brasses, ine inosvika 37% Zn, inonyatso ductile uye iri nyore kutonhora basa, weld uye braze. Iwo maviri echikamu alpha-beta brasses anowanzo kupisa anoshandiswa.
Pane zvinopfuura imwe brass yakagadzirwa here?
Kune akawanda mabhurasi ane akasiyana maumbirwo uye maitiro akarongedzerwa kune chaiwo maapplication nehuwandu hwekuwedzera zinc. Iwo akaderera mazinga eZn yekuwedzera anowanzo kunzi Guilding Metal kana Red Brass. Nepo iwo epamusoro mazinga eZn ari alloys akadai seCartridge Brass, Yemahara Machining Brass, Naval Brass. Aya mabhurashi akazotevera anewo kuwedzera kwezvimwe zvinhu. Kuwedzerwa kwemutobvu kundarira kwave kuchishandiswa kwemakore akawanda kubatsira machinability yezvinhu nekukwevera chip break point. Sezvo njodzi uye njodzi yemutobvu yakaonekwa ichangobva kutsiviwa nezvinhu zvakaita sesilicon uye bismuth kuti iwane yakafanana machining hunhu. Aya ave kuzivikanwa seakaderera lead kana lead yemahara brasses.
Zvimwe zvinhu zvinogona kuwedzerwa here?
Hongu, zvidiki zvidiki zvezvimwe zvinosanganiswa zvinhu zvinogonawo kuwedzerwa kumhangura nendarira. Mienzaniso yeCommons inotungamira yekugona-muchina sezvataurwa pamusoro, asiwo arsenic yekudzivirira ngura kune dezincification, tin yesimba uye ngura.
Brass Ruvara
Sezvo iyo zinc yemukati inowedzerwa, ruvara runoshanduka. Iyo yakaderera Zn alloys inogona kuwanzoita semhangura muruvara, nepo yakakwira zinc alloys inoratidzika yegoridhe kana yero.
