Umhlwa omhlophe yinto eyenzeka emva kwe-galvanizing. Uxanduva lothintelo luxhomekeke kwindlela epakishwa ngayo, iphathwa kwaye igcinwe ngayo phambi kokufakwa kunye nokusetyenziswa kwemveliso eyenziwe ngamagala. Ubukho bomhlwa omhlophe abubonakalisi ukusebenza kweentyantyambo, koko luxanduva lwabo bonke abo babandakanyekayo kwikhonkco lonikezelo lokuqinisekisa ukuba oonobangela bomhlwa omhlophe bayaqatshelwa kwaye imingcipheko yokwenzeka kwayo iyancitshiswa kwintsimbi esanda kwenziwa. Xa kufikwa eTshayina umbhobho ofakwe igalvanized eshushu, apho intsimbi esandul’ ukugalelwa ibhentshiswe kumanzi acocekileyo (imvula, umbethe okanye ukujiya), kwindawo enqongopheleyo yioksijini, amanzi aya kuqhubeka esabelana nezinki kwaye ngokuthe ngcembe asebenzise ukutyabeka. Eyona meko ixhaphakileyo apho kwenzeka khona umhlwa omhlophe ziimveliso ezenziwe ngamathangi ezidityaniswe kunye, zipakishwe ngokuqinileyo, okanye xa amanzi enokungena phakathi kwezinto kwaye ahlale ixesha elide.
Ngokuqhelekileyo, amanzi acocekileyo (H2O) ayinazo iityuwa okanye iiminerali ezinyibilikayo kwaye i-zinc iya kusabela ngokukhawuleza ngamanzi acocekileyo ukwenza i-zinc hydroxide, i-bulky emhlophe kunye ne-oxide engazinzanga ye-zinc. Umbhobho wentsimbi uquka i-conduit encinci ye-zinc edityaniswe kwi-substrate yentsimbi. Olu ludibaniso lubonelela ngezinto ezinomatshini wentsimbi eyongeziweyo ngokumelana nokubola kwe-zinc. Nangona kunjalo, emva kokuba i-galvanized surface ihlaselwe kwaye i-zinc hydroxide compounds yenziwe, kuyinqweneleka ukususa iimveliso ze-oxide ebusweni ngenxa yokuba: 1) ubukho babo buvimbela ukubunjwa kwe-carbonate based oxides; 2) azibukeki.
Ngokubhekiselele kumbhobho wentsimbi epholileyo, ukuphinda udlulise umphezulu we-galvanized lolunye unyango olubaluleke kakhulu kumbhobho wensimbi kwinkonzo. Ngokukodwa, apho kwenzeke khona ukurusa okumhlophe kwaye into leyo inokuba phantsi kokuvezwa okuqhubekayo okunokuthi kwandise ukubola okufanayo, ukuphinda kudlule umphezulu kunokwenziwa ngokuphatha umphezulu ngesisombululo se-5% ye-sodium dichromate 0.1% sulfuric acid, ibrashi yocingo eqinile imizuzwana engama-30 phambi kokuhlanjululwa ngokucokisekileyo komphezulu. Njengomvelisi wetyhubhu yentsimbi yaseTshayina eTshayina, singathanda ukubonelela ngamanyathelo alula anokunciphisa kakhulu okanye aphelise ukwenziwa komhlwa omhlophe ngolu hlobo lulandelayo ukuthelekelela kwakho:
• Gcina umsebenzi opakishiweyo womile
• Pakisha izinto ukuvumela ukujikeleza komoya phakathi komphezulu
• Beka izinto ezipakishiweyo ukuze amanzi aphume
• Phatha umphezulu ngesixhobo sokugxotha amanzi okanye isithintelo sokugquma ukunqanda ukuhlangana kokufuma kumphezulu ofakwe igalvanized.
Thumela umyalezo wakho kuthi:
