itsheyina lentsimbi lilungele iprojekthi yakho Umfanekiso obonisiweyo

ikhonkco lentsimbi lilungele iprojekthi yakho

Inkcazelo emfutshane:

Itsheyina lentsimbi elivuthelweyo yidiphu eshushu eyenziwe yazinki ngesiseko setyathanga lentsimbi elidityanisiweyo (oko kukuthi, i-zinc inyibilikiswa kwimbiza ye-zinc, kwaye ke ikhonkco lintywiliselwa kwi-zinc engamanzi kangangexesha elithile ukuyikhupha, kwaye emva koko ipholise kwaye yomiswe. ).Iindonga zangaphakathi nezangaphandle zekhonkco zinezinki ezincanyathiselwe kwangaxeshanye. Amatyathanga esinyithi enziwe ngegalvanized asetyenziswa ngokubanzi ukuhambisa ulwelo olunoxinzelelo oluphantsi (okt amanzi, igesi elulwelo).

Iinkcukacha zeMveliso

Iithegi zeMveliso

Itsheyini yentsimbi ekhandisiweyo kukusabela kwesinyithi esinyibilikisiweyo kunye ne-matrix yentsimbi ukuvelisa umaleko we-alloy, ukuze i-matrix kunye ne-coating zidityaniswe.Itsheyini yentsimbi ekhandisiweyo yitsheyini yokuqala yokuchola, ukuze kususwe i-oksidi yentsimbi kumphezulu wekhonkco, emva kokuchola, nge-ammonium chloride okanye i-zinc chloride isisombululo esinamanzi okanye i-ammonium chloride kunye ne-zinc chloride exutywe kwitanki yesisombululo esinamanzi sokucoca, kwaye emva koko. kwitanki yokufaka idiphu eshushu.Ikhonkco yentsimbi ene-galvanized ineenzuzo zokugquma okufanayo, ukunamathela okuqinileyo kunye nobomi obude benkonzo.

Itsheyini yentsimbi evundisiweyo yidiphu eshushu efakwe kwisiseko setsheyini yentsimbi edityanisiweyo (oko kukuthi, i-zinc iyanyibilika kwimbiza ye-zinc, kwaye ke ikhonkco lintywiliselwa kwi-zinc engamanzi kangangexesha elithile lokuthatha, kwaye emva koko ukupholisa nokomisa. ).
Iindonga zangaphakathi kunye nezangaphandle zekhonkco zine-zinc layer eqhotyoshelweyo ngexesha elifanayo.Amatyathanga entsimbi asetyenziswa ngokubanzi ukuhambisa ulwelo olunoxinzelelo oluphantsi (oko kukuthi, amanzi, igesi elulwelo).

Iimpawu ezibonakalayo zamatyathanga aqhelekileyo kunye namatyathanga e-galvanized ziyafana, kodwa ngenxa yokuba i-coat surface ihluke, ukuxhathisa ukubola akufani ncam.

Enye, ikhonkco eliqhelekileyo: i-chromium yintsimbi yombala wesilivere, izinzile kakhulu emoyeni, nakwi-alkali, i-nitric acid, i-sulfide, isisombululo se-carbonate inokugcina imeko ezinzileyo.I-Chrome inokwakheka okunzima, ukuxhathisa okuqinileyo, kwaye inokugcina ukukhanya kwayo ixesha elide.Ukungalungi kwe-chromium plating kukuba ayikhuseli isiseko sesinyithi kwi-rust.Ngoko ke ilandelwa yingubo yobhedu okanye i-copper-tin alloy ebophelela kakuhle kwisiseko sesinyithi.Ngokubanzi, ikhonkco le-chrome-plated lineempawu zeendleko eziphezulu, iimoto zasekhaya zodidi oluphezulu, iimoto eziphathwayo zihlala nazo, azikhuthazwa ukuba zisetyenziswe.

Emibini, ikhonkco legalvanized: inkangeleko yetsheyina legalvanized yombala oluhlaza.Esi sisiphumo sokunyanzeliswa kwe-zinc coating elandelwa yi-bleaching.Ingubo ye-zinc itshintsha kancinci emoyeni owomileyo.Kumoya omanzi, emanzini aqulethe i-carbon dioxide kunye neoksijini, umphezulu wayo wenza ifilimu ebhityileyo yesiseko se-zinc carbonate.Le filimu inefuthe lokuthintela ukubola.Inokuthintela ukuhlwa okungaphezulu kwesinyithi.Siyabona ukuba amanye amatyathanga aguquguquka ukusuka kumhlophe ukuya kumdaka ngokukhawuleza emva kokusetyenziswa, kodwa akukho tshintsho lukhulu emva koku, isizathu kukuba.

Xa kuthelekiswa namatyathanga aqhelekileyo, amatyathanga lagalvanized kwimveliso kunye nokucubungula emva konyango olukhethekileyo lwegalvanized, ekusetyenzisweni kweempawu ezigqwesileyo, ukuze nokuba kubomi bemveliso okanye ukusetyenziswa kwangempela koku kungasentla kunemigangatho eyahlukeneyo yokuphucula.Inkqubo yegalvanized ilula, ixabiso liphantsi, ngoko ke uhlobo oluqhelekileyo, ibhayisekile enzima isetyenziswa nayo.

Ngaphambili: intengiso yomzi-mveliso ngqo itheyiphu yokubhalisela

Okulandelayo: isikhonkwane isikhonkwane populat coil iinzipho kunye nezikhonkwane screw
