Umzi-mveliso wethu ugxininisa kumgaqo othi "uMgangatho wokuQala, uPhuhliso oluZinzileyo", kwaye uthatha "uShishino olunyanisekileyo, iiNzuzo eziBambiseneyo" njengenjongo yethu enokuphuhliswa. Onke amalungu enkosi ngokunyanisekileyo ngayo yonke inkxaso yabathengi abadala nabatsha. Siza kuqhubeka sisebenza nzima kwaye sikunika iimveliso ezikumgangatho ophezulu kunye nenkonzo.
Malunga nekhabhoni yentsimbi edityanisiweyo kunye nombhobho ongenamthungo, ukonyusa isakhono sokumelana nomhlwa, kuya kubakho uhlobo oluthile lonyango lomphezulu wombhobho. Enye yezona zinto zisetyenziswa kakhulu yi-zinc coat (galvanize). Zimbini iintlobo zendlela yokwenza i-galvanizing: i-glavanizing ebandayo (i-electrogalvanizing) kunye ne-galvanizing eshushu. Ngenxa yokuba ingxaki yendalo esingqongileyo, ukukhenkceza okubandayo kuthintelwe e-China, kwaye ukugalela amanzi ashushu nako akunakusetyenziswa njengombhobho wonikezelo lwamanzi, kodwa isetyenziswa ngokubanzi ekucimeni umlilo, umbane kunye nohola wendlela.
I-galvanizing ebandayo i-electrogalvanizing, ngenxa yomda wobugcisa, i-zinc coat ayininzi, ngokukodwa kwi-10-50g / m2, ngoko ke, amandla ayo okumelana nokubola angaphantsi kwe-galvanizing eshushu. I-Ofisi yoMphathiswa wezoKwakha ikuphelise ngokusesikweni ukupheliswa kwemibhobho ebandayo yamazinki ngobuchwephesha obubuya ngasemva, kwaye akuvumelekanga ukusebenzisa imibhobho ebanda yamazinki kwimibhobho yamanzi neyerhasi. Uluhlu lwe-galvanized ye-cold-dip galvanized pipe yi-electroplated layer, kwaye i-zinc layer kunye ne-substrate yombhobho wensimbi ifakwe ngokuzimeleyo. Uluhlu lwe-zinc luncinci, kwaye i-zinc layer ibambelela nje kwi-substrate yombhobho wensimbi kwaye kulula ukuwa. Ke ngoko, ukuxhathisa kwayo kukonakala.
Umbhobho we-alloy we-alloy layer ye-alloy eshushu yenziwa ngokuphendula kwesinyithi esityhidiweyo kunye ne-substrate yentsimbi, ukwenzela ukuba i-substrate kunye ne-plating layer idibaniswe, kwaye i-plating layer akulula ukuwa. I-Hot dip galvanizing ineenzuzo zokugquma okufanayo, ukunamathela okuqinileyo kunye nobomi benkonzo ende. I-substrate yentsimbi yombhobho wentsimbi eshushu-diphu kunye nesisombululo esinyibilikisiweyo se-plating sifumana iimpendulo ezintsonkothileyo zomzimba kunye neekhemikhali ukwenza umaleko we-alloy we-zinc-iron onganyangekiyo kunye nesakhiwo esibambeneyo. Uluhlu lwe-alloy luhlanganiswe ne-zinc ecocekileyo kunye ne-substrate yombhobho wensimbi, ngoko ukuxhathisa kwe-corrosion kunamandla.
Isicelo
Isetyenziswa ikakhulu kumandla kunye noxinzelelo lwamalungu, kunye nenjongo eqhelekileyo yomphunga, amanzi, igesi kunye nemibhobho yomoya.
