Umgangatho wokuqina kocingo lwentsimbi

Ubunzima buyisalathisi sepropathi esisetyenziswa ngokuqhelekileyo kwiipropati zemishini yezinto zetsimbi.Umzi-mveliso wocingo lwentsimbi wazisa indlela yovavanyo ekhawulezayo neyoqoqosho yovavanyo lokuqina.Nangona kunjalo, ngenxa yokuqina kwezixhobo zetsimbi, akukho nkcazo edibeneyo necacileyo, kubandakanya zonke iindlela zovavanyo ekhaya nakwamanye amazwe.Ngokubanzi, ukuqina kwentsimbi kudla ngokuthathwa njengokuchasana kwezinto kwi-deformation yeplastiki, imikrwelo, ukunxiba, okanye ukusika.

Ikhoyili enkuluucingo lwezinkikwi zinc ukuntywiliselwa kude debugging, gcina isantya yantlandlolo ingatshintshwanga, ngokutsho t = KD ukumisela ixesha lokuntywiliselwa zinc (1), apho: t lixesha lokuntywiliselwa zinc rhoqo, thatha 4-7D yi ububanzi ucingo lwentsimbi mm , kwaye ke uqikelele umgama wokuntywiliselwa zinc.Ngokuhlengahlengisa umgama wediphu ye-zinc, ixesha lokudipha i-zinc yocingo lwetsimbi lweenkcukacha ezahlukeneyo lunokufinyezwa ngama-5 ngokwe-avareji.Ngale ndlela, ukusetyenziswa kwe-zinc ngetoni yocingo lwentsimbi kuncipha ukusuka kwi-61kg ukuya kwi-59.4kg.
Idiphu eshushu yokuntywila ikwidiphu yediphu eshushu enyibilikayo, isantya soveliso, isambatho esityebileyo kodwa esingalinganiyo, imarike ivumela ubukhulu be-microns ezingama-45, ukuya kuthi ga kuma-300 eemicrons ngaphezulu.Imnyama ngombala, itya isinyithi se-zinc ngakumbi, yenza umaleko wokungenwa ngesiseko sentsimbi, kwaye inokumelana nokudumba okulungileyo.Idiphu eshushu yokuntywila ingagcinwa amashumi eminyaka kwindawo yangaphandle.Ukukhuselwa kwe-zinc coating kwi-matrix yensimbi kunemigaqo emibini: kwelinye icala, nangona i-zinc isebenza ngakumbi kwaye ilula i-oxidize kunentsimbi, kodwa ifilimu yayo ye-oxide ayikhululekile kwaye ihlangene njenge-iron oxide.Umaleko oshinyeneyo owenziwe phezu komphezulu unqanda i-oxidation eyongezelelweyo ye-zinc ngaphakathi.
Ngokukodwa emva kokugqithiswa komgangatho we-galvanized, umphezulu womgangatho we-oxide unzima kwaye uhlangene, ngokwawo unokumelana okuphezulu kwe-oxidation.Ngakolunye uhlangothi, xa umphezulu we-galvanized layer wonakalisiwe, uveza i-matrix yentsimbi yangaphakathi, kuba i-zinc isebenza ngakumbi kune-iron, i-zinc iya kuthwala indima yokubingelela i-zinc anode, i-zinc iya kuxutywa phambi kwentsimbi, ukuze ikhusele. umaleko wentsimbi awuyi konakaliswa.
