The difference between galvanized bridge and hot-dip galvanized bridge

Uhlaka lwebhuloho oluphekiwe:

Ibhuloho elinamathayela, elaziwa nangokuthi ibhuloho likagesi; Ngokuvamile liqondwa njengebhuloho elinothayela eliyibhuloho elinothayela elishisayo, empeleni, akulungile, njengepayipi elinothayela, ibhuloho eliwuthayela lihlukaniswe izinhlobo ezimbili, okungukuthi, elibandayo (elifakwe ugesi kagesi) kanye ne-hot-dip galvanized (hot-dip galvanized). );

I-ayoni nensimbi kugqwala kalula emoyeni, emanzini noma emhlabathini, noma konakale ngokuphelele. Ukulahlekelwa kwensimbi yonyaka okubangelwa ukugqwala kubala cishe i-1/10 yayo yonke insimbi ephumayo. Ngakolunye uhlangothi, ukuze wenze imikhiqizo yensimbi kanye nezingxenye zibe nomsebenzi okhethekile ebusweni, futhi unikeze ubuso bayo bokuhlobisa ukubukeka ngesikhathi esifanayo, ngakho-ke ngokuvamile kuvame ukuphathwa ngendlela ye-galvanizing kagesi.

1.Isimiso:

Ngenxa yokuthi i-zinc akulula ukuyishintsha emoyeni owomile, futhi emoyeni onomswakama, indawo engaphezulu ingakha ifilimu eyisisekelo ye-zinc carbonate eqinile, le filimu ingavikela ngokuphumelelayo ingaphakathi ekugqwaleni. Futhi lapho ukugqoka konakalisiwe ngesizathu esithile futhi isisekelo sensimbi asisikhulu kakhulu, i-zinc kanye ne-matrix yensimbi yenza i-microbattery, ukuze i-matrix yensimbi ibe yi-cathode futhi ivikelwe.

2. Izici Zokusebenza:

I-1) I-zinc enamathela iwugqinsi, i-crystallization ilungile, iyunifomu futhi ayinazo izimbotshana, futhi ukumelana nokugqwala kuhle;

2) Ungqimba lwezinc olutholwe nge-electroplating luhlanzekile futhi lugqwala kancane ku-asidi nenkungu ye-alkali, engavikela ngempumelelo i-matrix yensimbi;

3) Zinc enamathela eyakhiwe chromic acid passivation white, umbala, oluhlaza ezempi, enhle, has a zokuhlobisa ethile;

I-4) Ngenxa yokuthi ukugqoka kwe-zinc kune-ductility enhle, kungaba ukuvala okubandayo, ukugoqa, ukugoba nokunye ukwakha ngaphandle kokulimaza ukugqoka.

3. Ububanzi bohlelo lokusebenza:

Ngokuthuthuka kwesayensi nobuchwepheshe, imboni ye-electroplating ibandakanya izinkambu ezibanzi kakhulu. Njengamanje, ukusetshenziswa kwe-galvanizing bekukhona kuyo yonke iminyango yokukhiqiza nokucwaninga emnothweni wezwe. Isibonelo, ukukhiqizwa kwemishini, ogesi, amathuluzi anembayo, imboni yamakhemikhali, imboni elula, ezokuthutha, izikhali, i-aerospace, amandla e-athomu, nokunye, kubaluleke kakhulu emnothweni wezwe.

Ibhuloho elinothayela elishisayo(ibhuloho le-zinc elishisayo)

1, incazelo ye-zinc yediphu eshisayo:

I-Hot dip zinc ingenye yezindlela ezingcono kakhulu zokumboza zokuvikela i-substrate yensimbi. Isesimweni esiwuketshezi se-zinc, ngemva kokusebenza ngokomzimba namakhemikhali okuyinkimbinkimbi, hhayi kuphela kungqimba lwensimbi olujiyile olucwengekile lwezinc, kodwa futhi lukhiqiza ungqimba lwe-zinc - iron alloy. Le ndlela yokucwenga ayinazo kuphela izici zokumelana nokugqwala kwe-galvanizing, kodwa futhi inongqimba lwe-zinc-iron alloy. Ibuye ibe nokumelana nokugqwala okuqinile okungenakuqhathaniswa nokufaka i-galvanizing. Ngakho-ke, le ndlela yokucwenga ifaneleka ngokukhethekile zonke izinhlobo ze-asidi eqinile, inkungu ye-alkali nezinye imvelo eqinile yokugqwala.

2.Isimiso:

Isendlalelo se-zinc dip esishisayo sakhiwa ngezinyathelo ezintathu ngaphansi koketshezi olushisa kakhulu lokushisa:

1) Isisekelo sensimbi sincibilika ngesisombululo se-zinc ukwenza ungqimba lwesigaba se-zinc-iron alloy;

2) Ama-ion e-zinc ongqimba lwengxubevange aphinde asakazeke ku-matrix ukuze akhe ungqimba oluxubene lwe-zinc-iron;

3) Ingaphezulu le-alloy layer lifaka ungqimba lwe-zinc.

3. Izici zokusebenza:

(1) Ngongqimba oluqinile lwezinki oluminyene olumboze ingaphezulu lensimbi, ingagwema i-matrix yensimbi nanoma yikuphi ukuthintana kwesisombululo sokugqwala, ivikele i-matrix yensimbi ekugqwaleni. Emkhathini ojwayelekile, ingaphezulu lengqimba ye-zinc yakha indawo encane kakhulu futhi eminyene ye-zinc oxide layer, kunzima ukuyincibilika emanzini, ngakho idlala indima ethile yokuvikela ku-matrix yensimbi. Uma i-zinc oxide nezinye izakhi ezisemkhathini zenza usawoti we-zinc ongancibiliki, ukuvikela ukugqwala kungcono kakhulu.

(2) Kukhona ungqimba lwensimbi - ingxubevange ye-zinc, ehlangene, emkhathini we-Marine spray spray kanye nomkhathi wezimboni ukusebenza okuyingqayizivele ukumelana nokugqwala;

(3) Ngenxa yenhlanganisela eqinile, i-zinc-iron miscible, enokumelana okuqinile kokugqoka;

(4) Ngenxa yokuthi i-zinc ine-ductility enhle, ungqimba lwe-alloy yayo kanye nesisekelo sensimbi sinamathele ngokuqinile, ngakho izingxenye ezishisayo zokucwenga zingase zibe ukunyathela okubandayo, ukugoqa, ukudweba, ukugoba nezinye izinhlobo ngaphandle kokulimaza ukugqoka;

(5) Ngemva kokushiswa kwe-hot-dip galvanizing yezingxenye zesakhiwo sensimbi, kulingana nokwelashwa okukodwa kwe-annealing, okungathuthukisa ngempumelelo izakhiwo zemishini ye-matrix yensimbi, kuqede ukucindezelwa ngesikhathi kwakhiwa kanye nokushiselwa kwezingxenye zensimbi, futhi kulungele ukuphenduka. yezingxenye zesakhiwo sensimbi.

(6) Ingaphezulu lezesekeli ngemva kokuvuthwa kwediphu elishisayo liyakhanya futhi lihle.

(7) Ungqimba oluhlanzekile lwezinc luwungqimba oluningi lwepulasitiki lwengqimba eshisayo yediphu, izakhiwo zalo zisondelene ne-zinc ehlanzekile, i-ductility, ngakho-ke iyaguquguquka.

4. Ububanzi bohlelo lokusebenza:

Ukusetshenziswa kwe-hot dip galvanizing kuyakhula ngokuthuthukiswa kwezimboni nezolimo. Ngakho-ke, imikhiqizo efakwe emanzini ashisayo embonini (njengemishini yamakhemikhali, ukucutshungulwa kwe-petroleum, ukuhlola olwandle, isakhiwo sensimbi, ukudluliswa kwamandla, ukwakhiwa kwemikhumbi, njll.), ezolimo (njenge: ukuchelela, ukushisa ukushisa), ukwakhiwa (okufana nalokhu: amanzi kanye ukudluliswa kwegesi, i-wire casing, i-scaffolding, izindlu, amabhuloho, ezokuthutha, njll., sekusetshenziswe kabanzi eminyakeni yamuva nje imikhiqizo yama-Hot-dip galvanized isetshenziswa kabanzi ngenxa yokubukeka kwayo okuhle kanye nokuphikisana nokugqwala.

Okwesibili, umehluko phakathiibhuloho lokufuthafuthiibhuloho likathayela

Ibhuloho lokufutha kanye nebhuloho elinothayela kuhlukile kuphela ekusebenzeni, imininingwane, amamodeli, ukwakheka kanye nesakhiwo sebhuloho kuyafana.

Umehluko wenqubo phakathi kwebhuloho lesifutho kanye nebhuloho elinamathayela:

Okokuqala nje,ibhuloho likathayelafuthi ibhuloho lokufafaza ngepulasitiki lingelebhuloho lekhebula lensimbi, ibhuloho elinezinsimbi lenziwe ngepuleti lensimbi, ipuleti likathayela ngikholelwa ukuthi asikho isidingo sokuchaza okuningi, futhi ibhuloho lokufafaza ngepulasitiki lisetshenziselwa ukucubungula ungqimba lwe-electrostatic spraying layer phezu komhlaba. kwebhuloho elinamandla, ngakho-ke kubizwa ngokuthi ibhuloho lokufafaza ngepulasitiki, ukuqonda okulula ukuthi ibhuloho lokufafaza ngepulasitiki liyinguqulo yokuthuthukisa yebhuloho elinamandla, ukumelana nokugqwala kunamandla.
