idrama yonyango lwangaphambi konyango kunye nokuFudumeza
Ingcaciso yeMveliso
- Unyango lwangaphambi konyango yinkqubo ephambili yokugaya nge-hot-dip, enefuthe eliphambili kumgangatho weemveliso ze-galvanizing. Unyango lwangaphambi konyango luquka: ukususa amafutha, ukususa umhlwa, ukuhlamba ngamanzi, uncedo lokufaka iipleyiti, inkqubo yokomisa, njl.njl.
Okwangoku, kwishishini le-hot-dip galvanizing lasekhaya, itanki ye-granite pickling yekhonkrithi isetyenziswa kakhulu. Ngokuziswa kwetekhnoloji ye-hot-dip galvanizing ephucukileyo eYurophu naseMelika, iitanki ze-PP (polypropylene)/PE (polyethylene) pickling zisetyenziswa ngakumbi kwimigca yemveliso ye-hot-dip galvanizing ezenzekelayo.
Ngokuxhomekeke kubukhali bebala leoyile kumphezulu we-workpiece, ukususwa kwegrisi kuyasuswa kwezinye iinkqubo.
Itanki yokususa amafutha, itanki yokuhlamba amanzi kunye netanki yokuncedisa ukucoca iingcingo ngokubanzi zenziwe ngesamente, kwaye ezinye zenziwe ngezinto ezifanayo netanki yokucoca.
Ukufudumeza kwangaphambi konyango
Sebenzisa ubushushu obungasetyenziswanga begesi yolwelo ukufudumeza zonke iitanki zangaphambi konyango, kuquka nokususa amafutha,ukukhakunye ne-assistant plating. Inkqubo yokufudumala kwenkunkuma ibandakanya:
1) Ukufakelwa kwesixhobo sokutshintsha ubushushu esidibeneyo kwi-flue;
2) Iseti enye ye-PFA heat exchanger ifakelwe kuzo zombini iziphelo zedama ngalinye;
3) Inkqubo yamanzi athambileyo;
4) Inkqubo yokulawula.
Ukufudumeza ngaphambi konyango kuqulathe amacandelo amathathu:
① Umtshintshi wobushushu begesi yolwelo
Ngokwenani lilonke lobushushu obuza kufudunyezwa, i-combined flue heat exchanger yenzelwe kwaye yenziwe, ukuze ubushushu bukwazi ukuhlangabezana neemfuno zokufudumeza. Ukuba kuphela ubushushu obulahlekileyo be-flue abukwazi ukuhlangabezana neemfuno zobushushu bokufudumeza zonyango lwangaphambi konyango, iseti yesithando somoya oshushu singongezwa ukuqinisekisa ubungakanani begesi ye-flue.
Isitshintshi sobushushu senziwe ngentsimbi engagqwaliyo engatshiyo okanye umbhobho wentsimbi ongama-20 # onomphetho omtsha we-infrared nano high-temperature anti-corrosion coating. Amandla okufunxa ubushushu yi-140% yobushushu obufunxwa sisitshintshi sobushushu esiqhelekileyo.
② Isitshintshi sobushushu se-PFA
③I-oven yokomisa
Xa imveliso enomphezulu omanzi ingena kwi-zinc bath, iya kubangela ukuba ulwelo lwezinc luqhume kwaye lutshize. Ke ngoko, emva kwe-plating aid, inkqubo yokomisa nayo kufuneka isetyenziswe kwiindawo.
Ngokubanzi, ubushushu bokomisa akufuneki budlule kwi-100 ° C kwaye akufuneki bube ngaphantsi kwe-80 ° C. Ngaphandle koko, iindawo zinokubekwa kuphela kwindawo yokomisa ixesha elide, nto leyo eya kubangela ukufunxwa lula komswakama we-zinc chloride kwifilimu yetyuwa ye-plating aid kumphezulu weendawo.
