Amashishini amaninzi asebenzisa intsimbi ekhandiweyo kuba ihlala ixesha elide. Balandela imigangatho efana ne-ASTM A123/A123M kunye ne-ASTM A653.
Izinto eziphambili zokuThatha
Ishiti lentsimbi ekhandiweyo linomaleko otyebileyo we-zinc. Lo maleko unqanda amanzi nomoya ukuba ungachukumisi intsimbi. Oku kugcina intsimbi ingavuthwa.
I-Zinc inikezela ngokwayo ukugcina intsimbi. Iyarusa kuqala ukuze intsimbi ihlale ikhuselekile ekonakaleni.
Ukuba umaleko we-zinc uyakrweleka, unokuzilungisa ngokwawo. Igcina ikhusela intsimbi phantsi kwayo.
Ubukhulu be-zinc bubalulekile ukuba intsimbi ihlala ixesha elingakanani. I-zinc etyebileyo ithetha ukhuseleko olungcono lwentsimbi.
Ukucoca kunye nokujonga intsimbi efakwe igalvanized inceda ukuba ihlale yomelele. Ngokunyamekela, inokuhlala iminyaka engaphezu kwama-50.
UKhuseleko lwe-Zinc Coating
Isithintelo Isiphumo
Ishiti lentsimbi ekhandiweyo linekhaka eliqinileyo kulo. Ingubo ye-zinc isebenza njengodonga phakathi kwentsimbi kunye nomoya. Olu donga lugcina amanzi nomoya kude nentsimbi. Ukuba amanzi kunye nomoya akanakuchukumisa intsimbi, umhlwa awuyi kwenzeka.
IZinc ima phakathi kwamanzi, umoya, kunye nentsimbi ukuyikhusela.
I-Zinc yenza ikhaka lentsimbi, ukumisa umoya, amanzi, kunye nezinye izinto ekufikeni kuzo.
I-Shandong Sino Steel Co., Ltd isebenzisa igalvanization efakwe eshushu ukwenza umaleko oshinyeneyo we-zinc. Olu luhlu lugubungela zonke iintsimbi. Inceda intsimbi ukulwa nomhlwa kwaye ihlale ixesha elide kwiindawo ezinzima.
Oosonzululwazi bajonga ukuba iintsimbi zigada kakuhle kangakanani na izinki. Itheyibhile engezantsi ibonisa indlela ezahlukeneyo zokugquma ezisebenza:

Ixabiso elikhulu le-impedance lithetha ukhuseleko olunamandla. Uyabona ukuba i-zinc layer igcina intsimbi ikhuselekile ixesha elide.
Isenzo Sombingelelo
I-Zinc yenza okungakumbi kunokuvala nje amanzi nomoya. Ikwakhusela intsimbi ngokuzinikela kuqala. Xa iintsimbi ezimbini zichukumisa, njenge-zinc kunye nentsimbi, enye iya kuhlwa ngaphambi kwenye. I-Zinc ayinabunewunewu kunentsimbi, ngoko iyarusa kuqala. Oku kubizwa ngokuba yi-galvanic corrosion.
Ukonakala kwegalvanic kwenzeka xa umbane uhamba phakathi kweentsimbi ezimbini ezahlukeneyo. Isinyithi esine-anodic ngakumbi siya kugqwala ngokukhawuleza, ngelixa enye isinyithi ihlala ikhuselekile. I-Zinc ine-anodic kakhulu kunentsimbi, ngoko ke iyarusa kuqala xa ibamba into efana namanzi olwandle, igcina intsimbi ikhuselekile kumhlwa.
Ungakubona oku kwimigangatho yabo yokunciphisa enokwenzeka:
Isinyithi |
Amandla okuNcitshiswa okuMgangatho (V) |
Zinc |

Intsimbi |
-0.44 |
I-Zinc inamandla okunciphisa angaphantsi kunentsimbi.
Oku kuthetha ukuba i-zinc iyarusa phambi kokuba intsimbi yenze.
Xa i-zinc irusi, igcina i-iron ingavuthwa.
Umaleko we-zinc kwiphepha lentsimbi ekhandisiweyo uyazinika ukugcina intsimbi ikhuselekile. Yiyo loo nto abantu besebenzisa isinyithi ngaphandle kunye nokwakha izinto.
Ukuziphilisa
Ngamanye amaxesha, umaleko we-zinc uyakrweleka okanye ukrwele. Usenokucinga ukuba umhlwa ungaqala kwangoko. Kodwa intsimbi efakwe igalvanized inokuziphilisa. Xa i-zinc layer yonakele, i-zinc isakhusela intsimbi engaphantsi.
Inkcazo yobungqina |
Iziphumo eziphambili |
Ukukhuselwa kweCathodic ye-zinc |
I-Zinc isebenza njenge-anode kwaye izinikele ukukhusela intsimbi xa i-coating yonakalisiwe. |
Ubuninzi bomgama wokhuseleko |
I-Zinc inokukhusela intsimbi ukuya kuthi ga kancinane kune-1/4' (7 mm) kude, kodwa oku kuyehla njengoko umkrwelo usiya uba mkhulu. |
Impembelelo yomsebenzi womphezulu |
Ukuba i-zinc isebenza ngakumbi, ikhusela kude. Ukuba i-zinc ayisebenzi, ayikhuseli kakhulu. |
Kwintsimbi eshushu yokudipha, i-zinc kunye nentsimbi zithintana kakuhle.
Ukuba i-zinc layer yonakele kwaye kukho amanzi, iifom ze-galvanic cell. I-Zinc iba yi-anode kwaye ikhusela intsimbi.
Ekuqaleni, i-rust encinci ingabonakalisa kwintsimbi, kodwa kungekudala, i-zinc yenza umaleko omtsha okhusela intsimbi. Oku kubizwa ngokuba 'kuziphilisa'.
Oku kuziphilisa kugcina intsimbi yomelele kwaye ikhuselekile kumhlwa, nokuba iyakrweleka. Unokuthembela kwintsimbi ye-galvanized ukuze uzikhusele kwaye uhlale ixesha elide kwiindawo ezininzi.
Imiba echaphazela uKunyangwa kokuMhlwa
Okusingqongileyo
Kubalulekile ukucinga malunga nalapho usebenzisa khona intsimbi. Indawo oyikhethayo inokwenza i-zinc coating ihlale ixesha elide okanye iguge ngokukhawuleza. Ezinye iindawo zinamanzi amaninzi, ityuwa, okanye umoya omdaka. Ezi zinto zinokwenza ukuba i-zinc layer ihlehle ngokukhawuleza.
Nantsi itheyibhile ebonisa indlela izinto ezahlukeneyo zokusingqongileyo eziyichaphazela ngayo intsimbi enamazimba:
Umba wokusiNgqongileyo |
Inkcazo |
Ukubonakaliswa kweTyuwa |
Ityuwa kwintsimbi ngamanzi yenza umxube onxiba i-zinc coating ngokukhawuleza. |
Izingcolisi zemizi-mveliso kunye nezomoya |
Umoya omdaka onegesi kunye namanzi wenza iiasidi ezilimaza i-zinc layer. |
Ukufuma kunye Nokufuma |
Umoya omanzi ugcina amanzi kwintsimbi, enceda izinto ezibangela umhlwa kwaye yenza ukuba i-zinc layer iguge ngokukhawuleza. |
Iindawo zokutshiza ityuwa |
Izakhiwo ezikufuphi nolwandle okanye iindlela ezinetyuwa zinokugqwala ngokukhawuleza. |
Iigesi eziphuma kwimizi-mveliso |
Intsimbi ekufutshane nemizi-mveliso ibethwa ziigesi ezimbi ezikhawulezisa umhlwa. |
Ukuba sesichengeni semvula eneasidi |
Imvula eninzi eneasidi ingahlamba umaleko we-zinc kwintsimbi. |
Ukuba usebenzisa i-galvanized sheet sheet kufutshane nolwandle, ityuwa kunye nomoya unokuguga ngokukhawuleza. Umzekelo, intsimbi eshushu-dip galvanized isebenza kakuhle kufutshane nolwandle, kodwa ukuba ihlala ixesha elingakanani kuxhomekeke kwindawo. Ukuba ubeka isakhiwo esingaphantsi kweemayile ukusuka elwandle, sisenokuqalisa ukugqwala kwiminyaka emi-5 ukuya kwe-7 ukuba siye sabethwa sisitshizi solwandle. Ukuba uyibeka kwindawo enekhava, ingahlala iminyaka eyi-15 ukuya kwengama-25. Umoya, iqondo lobushushu, kunye nokuba ukufutshane kangakanani nolwandle konke oku kubalulekile kwindlela olulwa ngayo nomhlwa.
Ukutyeba kokutyabeka
Indlela ejiyile ngayo i-zinc ityabeka yenza umahluko omkhulu ekubeni intsimbi yakho efakwe igalvanized ihlala ixesha elingakanani. Ingubo etyebileyo inika ukhuseleko ngakumbi kwaye inceda ukuba ihlale ixesha elide. Unokujonga ukuba ukuqina kwengubo ngokujonga imigangatho efana ne-ASTM A653 okanye i-EN 10346.
Nantsi itheyibhile ebonisa ukuba ubukhulu bokutya butshintsha njani ukuba intsimbi ihlala ixesha elingakanani:
