Choj Galvanized, tseem hu ua choj hluav taws xob galvanized; Feem ntau nkag siab tias yog choj galvanized uas yog choj kub-dip galvanized, qhov tseeb, nws tsis yog, zoo li cov yeeb nkab galvanized, choj galvanized muab faib ua ob hom, uas yog, txias galvanized (hluav taws xob galvanized) thiab kub-dip galvanized (kub-dip galvanized);
Hlau thiab hlau yooj yim xeb hauv huab cua, dej lossis av, lossis puas tsuaj tag nrho. Kev poob hlau txhua xyoo los ntawm kev xeb yog li ntawm 1/10 ntawm tag nrho cov hlau tsim tawm. Ntawm qhov tod tes, txhawm rau ua kom cov khoom hlau thiab cov khoom muaj lub luag haujlwm tshwj xeeb ntawm qhov chaw, thiab muab nws qhov chaw zoo nkauj tib lub sijhawm, yog li nws feem ntau kho raws li txoj kev hluav taws xob galvanizing.
1. Txoj Cai:
Vim tias zinc tsis yooj yim hloov pauv hauv huab cua qhuav, thiab hauv huab cua noo, qhov saum npoo tuaj yeem tsim cov zaj duab xis zinc carbonate uas tuab heev, cov zaj duab xis no tuaj yeem tiv thaiv sab hauv kom tsis txhob xeb. Thiab thaum lub txheej puas tsuaj rau qee qhov laj thawj thiab lub hauv paus hlau tsis loj dhau, zinc thiab cov hlau matrix tsim cov roj teeb me me, yog li cov hlau matrix ua lub cathode thiab tiv thaiv.
2. Cov yam ntxwv ntawm kev ua tau zoo:
1) Cov txheej zinc yog tuab, qhov crystallization yog zoo, sib xws thiab tsis muaj qhov hws, thiab qhov corrosion tsis kam yog qhov zoo;
2) Cov txheej zinc uas tau los ntawm electroplating yog ntshiab thiab corrodes qeeb hauv acid thiab alkali pos huab, uas tuaj yeem tiv thaiv cov hlau matrix zoo;
3) Zinc txheej tsim los ntawm chromic acid passivation dawb, xim, tub rog ntsuab, zoo nkauj, muaj qee yam kho kom zoo nkauj;
4) Vim tias cov txheej zinc muaj cov ductility zoo, nws tuaj yeem ua kom txias, dov, khoov thiab lwm yam kev tsim yam tsis ua rau cov txheej puas tsuaj.
3. Daim ntawv thov:
Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, kev lag luam electroplating muaj ntau qhov chaw dav dua. Tam sim no, kev siv galvanizing tau siv thoob plaws hauv kev tsim khoom thiab kev tshawb fawb ntawm lub teb chaws kev lag luam. Piv txwv li, kev tsim tshuab, khoom siv hluav taws xob, cov cuab yeej siv precision, kev lag luam tshuaj lom neeg, kev lag luam lub teeb, kev thauj mus los, riam phom, aerospace, atomic zog, thiab lwm yam, yog qhov tseem ceeb heev rau lub teb chaws kev lag luam.
Choj kub-dip galvanized(choj zinc kub-dip)
1, kub dip zinc piav qhia:
Kev siv zinc kub yog ib txoj kev zoo tshaj plaws los tiv thaiv cov hlau. Nws nyob hauv lub xeev kua ntawm zinc, tom qab ua haujlwm ntawm lub cev thiab tshuaj lom neeg, tsis yog tsuas yog ua rau cov hlau plating tuab dua, tab sis kuj tsim cov zinc-hlau alloy txheej. Txoj kev plating no tsis yog tsuas yog muaj cov yam ntxwv ntawm kev tiv thaiv corrosion ntawm galvanizing, tab sis kuj muaj cov zinc-hlau alloy txheej. Nws kuj muaj kev tiv thaiv corrosion zoo uas tsis tuaj yeem piv rau galvanizing. Yog li ntawd, txoj kev plating no yog qhov tshwj xeeb tshaj yog rau txhua yam kua qaub, alkali pos huab thiab lwm yam kev tiv thaiv corrosion muaj zog.
2. Txoj Cai:
Cov txheej zinc kub dip yog tsim los ntawm peb kauj ruam hauv qab cov kua kub siab:
1) Qhov chaw hlau yog yaj los ntawm cov kua zinc los tsim cov txheej txheej zinc-hlau alloy;
2) Cov zinc ions hauv cov txheej alloy ntxiv mus rau hauv lub matrix los tsim cov txheej zinc-hlau sib xyaw ua ke;
3) Qhov saum npoo ntawm cov txheej hlau sib xyaw ua ke nrog cov txheej zinc.
3. Cov yam ntxwv ua tau zoo:
(1) Nrog ib txheej zinc tuab tuab uas npog saum npoo ntawm cov hlau, nws tuaj yeem zam kev sib cuag ntawm cov hlau matrix thiab txhua yam kev daws teeb meem corrosion, tiv thaiv cov hlau matrix los ntawm corrosion. Hauv huab cua dav dav, qhov chaw ntawm cov zinc txheej tsim ib txheej zinc oxide nyias thiab ntom ntom, nws nyuaj rau yaj hauv dej, yog li nws ua lub luag haujlwm tiv thaiv ntawm cov hlau matrix. Yog tias zinc oxide thiab lwm yam khoom hauv huab cua tsim cov ntsev zinc tsis yaj, kev tiv thaiv corrosion yog qhov zoo tagnrho.
(2) Muaj cov hlau-zinc alloy txheej, compact, nyob rau hauv Marine ntsev tsuag cua thiab industrial cua kev ua tau zoo tshwj xeeb corrosion tsis kam;
(3) Vim yog qhov sib xyaw ua ke ruaj khov, zinc-hlau sib xyaw ua ke, nrog kev tiv thaiv kev hnav zoo;
(4) Vim tias zinc muaj qhov ductility zoo, nws cov txheej alloy thiab cov hlau puag txuas ruaj khov, yog li cov khoom kub plating tuaj yeem ua rau txias stamping, dov, kos duab, khoov thiab lwm yam yam tsis ua rau lub txheej puas tsuaj;
(5) Tom qab kub-dip galvanizing ntawm cov khoom siv hlau, nws yog sib npaug rau ib qho kev kho mob annealing, uas tuaj yeem txhim kho cov khoom siv kho tshuab ntawm cov hlau matrix, tshem tawm kev ntxhov siab thaum lub sijhawm tsim thiab vuam ntawm cov hlau, thiab yog qhov zoo rau kev tig ntawm cov khoom siv hlau.
(6) Qhov saum npoo ntawm cov khoom siv tom qab kub dip galvanizing yog ci thiab zoo nkauj.
(7) Txheej zinc ntshiab yog txheej yas tshaj plaws ntawm cov txheej kub dip galvanized, nws cov khoom zoo li ze rau zinc ntshiab, ductility, yog li nws yooj ywm.
4. Daim ntawv thov:
Daim ntawv thov ntawm kev kub dip galvanizing nthuav dav nrog kev txhim kho ntawm kev lag luam thiab kev ua liaj ua teb. Yog li ntawd, cov khoom lag luam kub dip galvanized hauv kev lag luam (xws li cov khoom siv tshuaj lom neeg, kev ua roj av, kev tshawb nrhiav hauv dej hiav txwv, cov qauv hlau, kev xa hluav taws xob, kev tsim nkoj, thiab lwm yam), kev ua liaj ua teb (xws li: kev ywg dej, tsev cog khoom), kev tsim kho (xws li: kev xa dej thiab roj, hlau casing, scaffolding, vaj tse, Choj, kev thauj mus los, thiab lwm yam), tau siv dav hauv xyoo tas los no. Cov khoom lag luam kub dip galvanized tau siv dav dua vim lawv qhov zoo nkauj thiab tiv taus corrosion zoo.
Ob, qhov sib txawv ntawmchoj tsuagthiabchoj galvanized
Choj tsuag thiab choj galvanized tsuas yog txawv hauv cov txheej txheem, cov lus qhia, cov qauv, cov duab thiab cov qauv ntawm tus choj zoo ib yam.
Qhov sib txawv ntawm cov txheej txheem ntawm cov choj tsuag thiab cov choj galvanized:
Ua ntej tshaj plaws,choj galvanizedthiab cov yas txau choj yog cov hlau cable choj, galvanized choj yog ua los ntawm galvanized hlau phaj, galvanized phaj kuv ntseeg tias tsis tas yuav piav qhia ntau dhau, thiab cov yas txau choj yog siv los ua ib txheej ntawm electrostatic txau txheej rau ntawm qhov chaw ntawm galvanized choj, yog li nws hu ua yas txau choj, kev nkag siab yooj yim yog tias cov yas txau choj yog qhov hloov kho dua tshiab ntawm galvanized choj, kev tiv thaiv corrosion yog muaj zog dua.
Yog tias koj xav tau cov khoom no, koj tuaj yeem nyem rau ntawm kaum sab xis hauv qab, peb yuav tiv tauj koj sai li sai tau.
