Zn Hotplating

Iibhulorho kunye noLwakhiwo lwentsimbi:

Isetyenziselwa ukudibanisa iindawo ezinjengeebhodi eziphambili zebhulorho, iitrasi, iindawo zokugada, njl., ukuxhathisa ukubola kumanzi emvula kunye nee-agent ezinyibilikisa ikhephu (iityuwa ze-chloride).

Ngokomzekelo, iibholithi zebhulorho enqumla ulwandle kufuneka zikwazi ukumelana nokufuma nokhukuliseko lwesitshizi setyuwa, yaye umaleko owenziwe ngamazinki ashushu unokukhusela ngaphezu kweminyaka engama-20.

Oohola bendlela kunye noololiwe:

Iintsimbi zokugada ezizinzileyo, iipaneli zokugquma isandi, kunye neziqhoboshi zokulandelela ukujongana nemvula eneasidi, umbhobho wemoto (i-sulphur dioxide), kunye nongcoliseko lwemizi-mveliso.

Iinqaba zothumelo kunye neenqaba zonxibelelwano:

Isetyenziselwa ukudibanisa iziseko zentsimbi kunye neengalo ezinqamlezayo, inokumelana imitha ye-ultraviolet, iindudumo, kunye nemekobume yenkungu yeasidi kwiindawo eziphakamileyo.

2. Ubunjineli baseLwandle kunye nePort
Izixhobo zedokhi:

Iifender ezilungisiweyo, iintsika zokuhombisa, iimfumba zentsimbi, kunye nokuntywiliselwa ixesha elide emanzini olwandle ukuxhathisa ukubola kwe-ion yekloride.

Ukugcinwa rhoqo (okufana nokupeyintwa ngokutsha ngepeyinti enqanda umhlwa) kuyafuneka ukwandisa ubomi.

Iinqanawa kunye namaqonga angaphesheya kolwandle:

Uqinisekiso lwezixhobo zedekhi kunye nezixhaso zemibhobho kufuneka luphumelele uvavanyo lwe-ISO 9227 lokutshiza ngetyuwa (akukho rusa ebomvu ngaphezu kweeyure ezili-1000).

Qaphela: Ubume bolwandle bunzulu bunokufuna ukuphuculwa ukuya kukhuseleko oluntlu-mbini lwe-galvanizing yediphu eshushu kunye nokwaleka kwe-epoxy.

3. Amacandelo oshishino kunye namandla
Izixhobo zekhemikhali:

Isibiyeli setanki yokusabela esisigxina, i-flange yombhobho, ukumelana ne-acidic kunye neegesi ze-alkaline (ezifana ne-hydrogen sulfide), ubushushu obuphezulu kunye nemekobume yokufuma okuphezulu.

Iimeko ezisebenzayo: Izixhobo zangaphandle kwizityalo zekhemikhali kunye neendawo zokucoca.

Amandla omoya kunye ne-photovoltaics:

Iibholiti ze-injini yomoya kufuneka zimelane nokungcangcazela komthwalo womoya, isitshizi setyuwa elunxwemeni, kunye nomahluko wobushushu (-30 ° C ukuya ku-50 ° C).

Iibholithi zebrakethi ye-photovoltaic kufuneka zixhathise ukuguga kwe-UV kwaye zigweme ukugquma umgubo (i-hot-dip galvanizing ingcono kune-electroplating galvanizing).

Amaziko ezolimo:

I-Greenhouse steel frame kunye nezixhobo zokunkcenkceshela izixhobo zokunkcenkceshela ukuthintela ukubola okubangelwa yimeko efumileyo yexesha elide.

4. Amaziko kamasipala kunye noluntu
Izibane zesitalato kunye nezibane zemiqondiso:

Isiseko sesibane sesibane kunye ne-cantilever zilungiswe ukuxhathisa ukukhukuliseka kwemvula ye-asidi yasezidolophini kunye nee-agent ezinyibilikayo zekhephu.

Indawo yokucoca ugutyulo:

Isakhiwo sentsimbi esidibanisa itanki yomoya kunye ne-sedimentation tank iyamelana negesi ye-hydrogen sulfide kunye nokutshiza kwamanzi amdaka.

5. Iimeko eziKhethekileyo kunye neZilumkiso
Iindawo zealkali ezinetyuwa eninzi:

Umzekelo, kumntla ntshona kumhlaba wealkali onetyuwa kunye neendawo eziselunxwemeni lwentlango yoMbindi Mpuma, iibholithi ezishushu zediphu kufuneka zigqunywe ngongqimba olungqindilili (≥ 80 μ m).

Indawo yokungcangcazela:

Iibholithi zemizila kaloliwe kunye noomatshini basemigodini kufuneka zitshatiswe namandongomane anqanda ukukhulula (afana namandongomane okutshixa inayiloni) ukunqanda ukuhexa ngenxa yokungcangcazela.

Indawo yobushushu obuphezulu:

Iimeko zexesha elide ezingaphezulu kwe-200 ° C, ezinje ngeebhoyila, zinokukhawulezisa i-oxidation ye-zinc layers kwaye ifune ukusetyenziswa kwentsimbi engatyiwa okanye iibholiti ezifakwe kwi-zinc.

Iingcebiso zokukhetha
Imekobume erhabaxa: Beka phambili iibholiti ezishushu zediphu kwaye usebenzise izinto zokutywina (ezifana nonyango lwe-phosphating) okanye izinto ezidityanisiweyo.

Iimeko ezinovakalelo lweendleko: Iiprojekthi zexesha elifutshane okanye iimeko ezingqongileyo zomhlwa (ezifana neendawo ezomileyo zangaphakathi) zingakhetha ukwenza igalvanizing, kodwa ukuhlolwa rhoqo kuyafuneka.

Imfuneko yamandla aphakamileyo: Iibholiti zebanga le-10.9 nangaphezulu kufuneka zingene kunyango lwe-dehydrogenation ukuphepha umngcipheko we-hydrogen embrittlement kunye nokwaphuka.

shwankathela
Iibholiti ezishushu zediphu lukhetho "lwenqanaba lokhuselo" kwindawo ezonakalisa kakhulu, ngakumbi zilungele ngaphandle, elwandle, kwiikhemikhali kunye nezinye iimeko. Ixabiso layo elingundoqo lixhomekeke ekutshintshiseni ngeendleko eziphezulu zokuqala ngeendleko eziphantsi kakhulu zokugcinwa kwesithuba, oko kuyenza ifanelekele iiprojekthi ezineemfuno eziphezulu zokhuseleko kunye nokuqina.
