igubu lonyango lwangaphambili & Ukufudumeza

Inkcazelo emfutshane:

I-PRETREATMENT DRUM & HEATING sisiqwengana sesixhobo esisetyenziswa kwimveliso yefektri ukunyanga imathiriyeli ekrwada. Ngokuqhelekileyo iqulethe i-barrel ejikelezayo yonyango kunye nenkqubo yokufudumeza. Ngethuba lokusebenza, izinto eziluhlaza zifakwe kwi-barrel ejikelezayo yonyango yangaphambili kwaye ifudunyezwe yinkqubo yokufudumala. Oku kunceda ukutshintsha izinto eziphathekayo okanye iikhemikhali zezinto eziluhlaza, okwenza kube lula ukuphatha ngexesha leenkqubo zokuvelisa ezilandelayo. Olu hlobo lwezixhobo ludla ngokusetyenziswa kwimichiza, ekusetyenzweni kokutya, kumayeza nakwamanye amashishini ukuphucula ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso.

igubu lonyango lwangaphambili & Ukufudumeza

Unyango lwangaphambili yinkqubo ephambili ye-hot-dip galvanizing, enefuthe eliphambili kumgangatho weemveliso zegalvanized. Ukufudumeza kwangaphambi kokunyanga kubandakanya: ukuhlamba, ukususwa kwe-rust, ukuhlamba amanzi, i-plating aid, inkqubo yokomisa, njl.
Okwangoku, kwishishini lasekhaya le-hot-dip galvanizing, itanki ye-granite pickling yekhonkrithi isetyenziswa kakhulu. Ngokungeniswa kweteknoloji ye-galvanizing ye-hot-dip ephezulu eYurophu naseMelika, i-PP (i-polypropylene) / i-PE (i-polyethylene) i-pickling tanks isetyenziswa ngakumbi kwimigca yokuvelisa i-galvanizing ye-automatic.

Ngokuxhomekeke kubunzima bebala leoli kwindawo yokusebenza, ukukhutshwa kwegreasing kupheliswa kwezinye iinkqubo.

Itanki yokucoca, itanki yokuhlamba amanzi kunye netanki yokuncedisa i-plating ngokuqhelekileyo yesakhiwo sekhonkrithi, kwaye ezinye zenziwe ngezinto ezifanayo njengetanki yokukha.

Ukufudumala kwangaphambili

Sebenzisa inkunkuma yobushushu berhasi yombane ukufudumeza onke amatanki onyango lwangaphambili, kubandakanya nokususa amafutha,ukukhakunye neplating encedisayo. Inkqubo yobushushu benkunkuma ibandakanya:
1) Ukufakwa komtshintshi wokushisa odibeneyo kwi-flue;
2) Iseti enye yePFA yokutshintsha ubushushu ifakwe kuzo zombini iziphelo zedama ngalinye;
3) Inkqubo yamanzi ethambileyo;
4) Inkqubo yokulawula.
Ukufudumeza kwangaphambi kokunyangwa kunamacandelo amathathu:
① Umtshintshi wobushushu berhasi eFlue
Ngokwexabiso elipheleleyo lobushushu eliza kutshiswa, i-flue edibeneyo yokushisa idityanisiwe yenziwe kwaye yenziwe, ukwenzela ukuba ubushushu bukwazi ukuhlangabezana neemfuno zokufudumeza. Ukuba kuphela ubushushu benkunkuma ye-flue ayikwazi ukuhlangabezana nemfuno yokushisa yokufudumala yonyango lwangaphambili, isethi yesithando somlilo esishushu sinokudibaniswa ukuze kuqinisekiswe umthamo wegesi ye-flue.
Umtshintshi wobushushu wenziwe ngentsimbi enganyangekiyo okanye i-20 # ipayipi yentsimbi engenamthungo ene-infrared nano high-temperature-energy-saving-anti-corrosion coating. Amandla okufunxa ubushushu yi-140% yobushushu obufunxwa yinkunkuma eqhelekileyo yokutshintsha ubushushu.
② PFA umtshintshi wobushushu
③Ukomisa i-oveni
Xa imveliso enomhlaba omanzi ingena kwibhafu ye-zinc, iya kubangela ukuba ulwelo lwezinki luqhume kwaye lutshize. Ngoko ke, emva koncedo lokucoca, inkqubo yokumisa kufuneka yamkelwe kwakhona kwiindawo.
Ngokuqhelekileyo, iqondo lokushisa lokumisa akufanele lidlule i-100 ° C kwaye akufanele libe ngaphantsi kwe-80 ° C. Ngaphandle koko, iinxalenye zinokufakwa kuphela emhadini wokomisa ixesha elide, eliya kubangela lula ukufunxa umswakama we-zinc chloride kwityuwa. ifilimu yoncedo lweplating kumphezulu wamalungu.
