Ingqele galvanizing izandla zabo

Nokumelana zesinyithi lwenzeka xa zidibene yayo mpilo komoya. Ukuze uphephe oku kwaye wandise ubomi inkonzo iimveliso izihlandlo ezimbalwa, kuyimfuneko ukwenza isethi amanyathelo akhuselayo. Galvanizing isetyenziswa ngokubanzi. Le nkqubo iqulathe ekusebenziseni umaleko zinc phezu komhlaba nqaku. Le nkqubo ingathatha indawo ngeendlela ezahlukahlukeneyo.

imihlobo ukusebenza

Ukuza kuthi ga ngoku, uphuhliso lwabafundi inkqubela ukuvumela ukusetyenziswa ntlobo zilandelayo:

- kubanda galvanizing metal;

- hot;

- nokuhanjiswa;

- Electrolytic;

- shoopirovanie;

- igesi-linamandla.

Ngokwahlukeneyo, malunga indlela nganye ngazo kamva.

Chonga uhlobo galvanizing

Ukunaba kungaba ingqalelo iintlobo ezimbini - ashushu kunye electrolytic. Kule ndlela yokuqala, ebizwa kwakhona electroplated, ifowuni ifuna umgca yonke imveliso kwi. Kodwa le ndlela ayikho kakuhle kakhulu umhlwa. Noko ke, oko kunika imveliso nenkangeleko entle shiny. Ngoko sebenzisa galvanizing electrolytic kuphela ukulungiselela iinjongo zokuhombisa.

Hot-dip indlela galvanizing - umthambo esixabiso likhulu kunene. Ukuphumeza oko, into kufuneka ukuntywiliselwa ngokupheleleyo zinc otyhidiweyo. Le nkqubo yenziwa kuphela kumgangatho mveliso kwaye ifuna amandla amaninzi kunye nomzamo. Umphezulu imveliso ifunyenwe kwi non-ezenziwe matte. Kodwa umaleko ixesha elide ukuze bakwazi ukuthelekisa kwinkcaso umhlwa of insimbi.

galvanizing ashushu nabandayo lusekiwe kakuhle njengendlela ukukhusela metal. Xa isicelo komhlaba powder imveliso nezinki okanye umphunga, esebenzisa ubushushu, le nkqubo ibizwa ngokuba kwe- ngeso lenyama. Ukuba zinc ukwimeko etyhidiweyo lisetyenziswa umpu, ezifana umbala, oko shoopirovanie.

Inkqubo yokwenza isicelo zinc usebenzisa flow supersonic - daka gas-linamandla. Loo ndlela sele adhesion ophezulu kunye kuluncedo kakhulu kule nkalo xa kuthelekiswa nabanye.

Zonke ezi ndlela kube lula eziku ngomlinganiselo yorhwebo kwindawo yemveliso ezikhethekileyo, kodwa apha ekhaya, ezi nkqubo inzima kakhulu ukuyisebenzisa, kwaye kwezinye iimeko akunakwenzeka.

Kubume metal uza kuhlangabezana neemfuno kunye imiqathango yokusebenza, kufuneka zenziwe ngokungqinelana nemiqathango kwamaxwebhu eqhelekileyo. Ngokucacileyo kuchazwa iimfuno utyelelo enjalo.

Dip kwalenza ebandayo - yeyona ndlela iqhelekileyo nezifikelelekayo ukukhusela intsimbi evela umhlwa. It Akuyomfuneko izixhobo ezikhethekileyo kunye neenkqubo zokuvelisa ezintsonkothileyo. Isicelo se ubume zinc aqulethe akukho nzima kakhulu kunonyango ipeyinti. Umxholo ekwakhiweni, apho iveliswa kubanda metal galvanizing, kulawulwa ngokucacileyo ngu GOST. Kufuneka ube ubuncinane 94 ekhulwini zinc.

Yintoni na le nto?

Izinki yinto efunekayo imichiza ngoweqela zesinyithi. Lubonakala ngumntu umbala ubuhle-omhlophe. Xa uhlobo yayo enyulu isiphathele isakhiwo kunokuba ethe-ethe. Idityaniswe emoyeni esesibhakabhakeni, oko kukuthi, kunye namacandelo ayo: icarbon dioxide neoksijini. Ngenxa kule asabela kubonakala phezu komhlaba oxide, leyo amandla aphezulu lib, kwaye ayikho phantsi ngamanyala.

zinc electrochemical izinga enokubakho kuncitshiswa ngesiqingatha xa kuthelekiswa ne-ayini. Ngoko ke, lo ephindeneyo ngeembadada i anode kunye cathode zinc - yentsimbi. Xa baboniswa ukufuma komoya idityaniswe zinc kwi indlela, kunye carbonate kwakhiwa. Yaba yena oxide wakhe lichithakale, kwaye imveliso isale film.
