The difference between galvanized bridge and hot-dip galvanized bridge

Isakhelo sebhulorho ekhandisiweyo:

ibhulorho efakwe igalvanized, ekwabizwa ngokuba yibhulorho yombane; Ngokuqhelekileyo iqondwa njengebhulorho enamazimba eshushu-diphu ibhulorho eyenziwe ngamagalvanized, enyanisweni, ayilunganga, njengombhobho owenziwe amazinki, ibhulorho eyenziwe ngamazimba yahlulwe yazintlobo ezimbini, ezizezi, igalvanized ebandayo (igalvanized yombane) kunye nediphu eshushu (got-dip galvanized). );

Intsimbi kunye nentsimbi zirusa ngokulula emoyeni, emanzini okanye emhlabeni, okanye zonakaliswe ngokupheleleyo. Ilahleko yentsimbi yonyaka ebangelwa yi-corrosion akhawunti malunga ne-1/10 yemveliso yensimbi yonke. Ngakolunye uhlangothi, ukuze wenze iimveliso zetsimbi kunye neengxenye zinomsebenzi okhethekileyo phezu komhlaba, kwaye zinike imbonakalo yayo yokuhlobisa ngexesha elifanayo, ngoko ngokuqhelekileyo iphathwa ngendlela yombane.

1.Umgaqo:

Ngenxa yokuba i-zinc akulula ukuyitshintsha emoyeni owomileyo, kwaye emoyeni omanzi, umphezulu unokwenza ifilimu ye-zinc carbonate ephantsi kakhulu, le filimu inokukhusela ngokufanelekileyo ingaphakathi kwi-corrosion. Kwaye xa iingubo zonakaliswe ngenxa yesizathu esithile kwaye isiseko sensimbi asisikhulu kakhulu, i-zinc kunye ne-matrix yensimbi yenza i-microbattery, ukwenzela ukuba i-matrix yensimbi ibe yi-cathode kwaye ikhuselwe.

2. Iimpawu zoMsebenzi:

I-1) I-coating ye-zinc inzima, i-crystallization ilungile, iyunifomu kwaye ayikho i-pores, kunye nokumelana nokubola kulungile;

2) I-zinc layer efunyenwe nge-electroplating ihlambulukile kwaye i-corrodes ngokukhawuleza kwi-asidi kunye nenkungu ye-alkali, enokukhusela ngokufanelekileyo i-matrix yensimbi;

3) I-Zinc yokugqoka eyenziwe yi-chromic acid passivation emhlophe, umbala, uhlaza lomkhosi, umhle, unomhlobiso othile;

I-4) Ngenxa yokuba i-zinc i-coating ine-ductility enhle, ingaba yi-blank blanking, i-rolling, i-goba kunye nokunye ukubumba ngaphandle kokonakalisa i-coating.

3. Umda wesicelo:

Ngophuhliso lwesayensi kunye nethekhinoloji, ishishini le-electroplating libandakanya amasimi abanzi nangakumbi. Okwangoku, ukusetyenziswa kwe-galvanizing bekuye yonke imveliso kunye nophando lwamasebe oqoqosho lwesizwe. Umzekelo, ukuveliswa koomatshini, i-electronics, izixhobo ezichanekileyo, imboni yekhemikhali, ishishini elilula, ukuthutha, izixhobo, i-aerospace, amandla e-athomu, njalo njalo, zibaluleke kakhulu kuqoqosho lwelizwe.

Ibhulorho efakwe amakhati eshushu-diphu(ibhulorho yezinc eshushu)

1, inkcazo ye-zinc yediphu eshushu:

I-zinc dip eshushu yenye yezona ndlela zibalaseleyo zokugquma zokukhusela i-steel substrate. Ikwimeko yolwelo lwezinki, emva kwentshukumo entsonkothileyo yomzimba kunye neekhemikhali, hayi kuphela kwiplating yentsimbi etyebileyo yomaleko we-zinc esulungekileyo, kodwa ikwavelisa i-zinc - umaleko we-iron alloy. Le ndlela yokucoca ayinayo kuphela iimpawu zokumelana ne-corrosion ye-galvanizing, kodwa inomaleko we-zinc-iron alloy. Ikwanayo nokumelana ne-corrosion eyomeleleyo engenakufaniswa ne-galvanizing. Ke ngoko, le ndlela yokucwenga ilungele zonke iintlobo zeasidi eyomeleleyo, inkungu yealkali kunye nokunye okusingqongileyo okunomhlwa okuqinileyo.

2.Umgaqo:

Umaleko wedip eshushu we-zinc wenziwe ngamanyathelo amathathu phantsi kolwelo lobushushu obuphezulu:

1) Isiseko sesinyithi sichithwa yisisombululo se-zinc ukwenza i-zinc-iron alloy phase layer;

2) I-zinc ion kwi-alloy layer isasazeka ngakumbi kwi-matrix ukwenza i-zinc-iron edibeneyo edibeneyo;

3) Umphezulu woluhlu lwe-alloy uvalela i-zinc layer.

3. Iimpawu zokusebenza:

(1) Ngomaleko oshinyeneyo oshinyeneyo ococekileyo we-zinc ogqume umphezulu wentsimbi, unokunqanda i-matrix yentsimbi kunye naluphi na unxibelelwano lwesisombululo somhlwa, ukukhusela i-matrix yentsimbi ekudlekeni. Kwi-atmosphere jikelele, umphezulu we-zinc layer yenza i-zinc oxide layer layer kakhulu kwaye ixineneyo, kunzima ukuyichitha emanzini, ngoko idlala indima ethile yokukhusela kwi-matrix yensimbi. Ukuba i-zinc oxide kunye nezinye izinto ezisemoyeni zenza ityuwa ye-zinc enganyibilikiyo, ukukhuselwa kwe-corrosion kulungele ngakumbi.

(2) Kukho i-iron - i-zinc alloy layer, i-compact, kwi-Marine i-atmosphere yetyuwa yokutshiza kunye ne-industry atmosphere ukusebenza ukuxhathisa okukodwa kokuhlwa;

(3) Ngenxa yokudibanisa okuqinileyo, i-zinc-iron miscible, kunye nokumelana okunamandla;

(5) Emva kwe-galvanizing eshushu-dip yamalungu esakhiwo sentsimbi, ilingana nonyango olulodwa lwe-annealing, olunokuthi luphucule ngokufanelekileyo iimpawu zomatshini we-matrix yensimbi, ukuphelisa uxinzelelo ngexesha lokuqulunqa kunye ne-welding yamacandelo ensimbi, kwaye ilungele ukujika. yamalungu olwakhiwo lwentsimbi.

(6) Umphezulu wezixhobo emva kokutshisa idiphu galvanizing iqaqambile kwaye intle.

4. Umda wesicelo:

Ukusetyenziswa kokugalelwa kwediphu eshushu kuyakhula ngophuhliso loshishino nezolimo. Ngoko ke, iimveliso ezishushu-dip kushishino (ezifana izixhobo imichiza, processing petroleum, ukuhlola Marine, isakhiwo metal, ukuhanjiswa kwamandla, shipbuilding, njl.), ezolimo (ezifana: zokunkcenkceshela, greenhouse), ulwakhiwo (ezifana: amanzi kunye ukuhanjiswa kwegesi, i-wire casing, i-scaffolding, izindlu, iiBridges, ezothutho, njl. njl., isetyenziswe ngokubanzi kwiminyaka yamuva nje iimveliso ze-galvanized ze-Hot-dip zisetyenziswa ngokubanzi ngenxa yenkangeleko yazo entle kunye nokuxhathisa ukubola.

Isibini, umahluko phakathiibhulorho yokutshizakwayeibhulorho enezibilini

Ibhuloho yokutshiza kunye nebhuloho eneentsimbi zihluke kuphela kwinkqubo, iinkcukacha, iimodeli, imilo kunye nesakhiwo sebhulorho ziyafana.

Umahluko wenkqubo phakathi kwebhulorho yokutshiza kunye nebhulorho enamazimba:

Okokuqala,ibhulorho eyenziwe ngamabatikunye nebhulorho yokutshiza ngeplastiki yeyentsimbi yebhulorho yentambo, ibhulorho eyenziwe ngentsimbi yenziwe ngepleyiti yentsimbi, ipleyiti enabileyo ndiyakholwa ukuba akukho mfuneko yokuchaza kakhulu, kwaye ibhulorho yokutshiza yeplastiki isetyenziselwa ukucwangcisa umaleko wokutshiza nge-electrostatic phezu komhlaba. kwebhulorho amazimba, ngoko ke kuthiwa ibhulorho yokutshiza zeplastiki, ukuqonda elula kukuba ibhulorho yokutshiza iplastiki yinguqulelo yokuphucula ibhulorho amazi, ukumelana umhlwa womelele.
