Isakhelo sebhulorho esenziwe ngesinyithi:
Ibhuloho eligalelwe igesi, ekwaziwa ngokuba yibhuloho eligalelwe igesi; Ngokuqhelekileyo iqondwa njengebhuloho eligalelwe igesi elibizwa ngokuba yibhuloho eligalelwe igesi elishushu, eneneni, ayilunganga, njengombhobho ogalelwe igesi, ibhuloho eligalelwe igesi lahlulwe laba ziintlobo ezimbini, ezizezi, i-cold galvanized (electric galvanized) kunye ne-hot-dip galvanized (hot-dip galvanized);
Ukugqwala kwentsimbi kunye nentsimbi kulula emoyeni, emanzini okanye emhlabeni, okanye nokuba yonakele ngokupheleleyo. Ukulahleka kwentsimbi yonyaka okubangelwa kukugqwala kubangela malunga ne-1/10 yemveliso yonke yentsimbi. Kwelinye icala, ukuze kwenziwe iimveliso zentsimbi kunye neenxalenye zayo zibe nomsebenzi okhethekileyo kumphezulu, kwaye zinike umphezulu wazo inkangeleko yokuhombisa ngaxeshanye, ngoko ke ngokubanzi iphathwa ngendlela ye-electromagnetic galvanizing.
1. Umgaqo:
Ngenxa yokuba i-zinc ayilula ukuyitshintsha emoyeni owomileyo, nakumoya ofumileyo, umphezulu unokwenza ifilimu ye-zinc carbonate exineneyo kakhulu, le filimu inokukhusela ngokufanelekileyo ingaphakathi ekuboleni. Kwaye xa uphahla lonakele ngesizathu esithile kwaye isiseko sentsimbi singesikhulu kakhulu, i-zinc kunye ne-matrix yentsimbi zenza i-microbattery, ukuze i-matrix yentsimbi ibe yi-cathode kwaye ikhuselwe.
2. Iimpawu Zokusebenza:
1) Ingubo ye-zinc ityebile, i-crystallization ilungile, iyafana kwaye ayinazo iimbobo, kwaye ukumelana nokugqwala kulungile;
2) Umaleko we-zinc ofunyenwe nge-electroplating ucocekile kwaye udla kancinci kwi-asidi kunye ne-alkali fog, nto leyo enokukhusela ngempumelelo i-matrix yentsimbi;
3) I-Zinc coating eyenziwe yi-chromic acid passivation emhlophe, enombala, eluhlaza okomkhosi, entle, inomhombiso othile;
4) Ngenxa yokuba i-zinc coating ine-ductility elungileyo, inokuba yi-blanking ebandayo, i-rolling, i-gobile kunye nezinye izinto ngaphandle kokonakalisa i-coating.
3. Ububanzi besicelo:
Ngophuhliso lwesayensi netekhnoloji, ishishini lokufaka i-electroplating libandakanya amasimi abanzi ngakumbi nangakumbi. Okwangoku, ukusetyenziswa kwe-galvanizing kuye kwasebenza kuwo onke amasebe emveliso nophando kuqoqosho lwesizwe. Umzekelo, ukuveliswa koomatshini, izixhobo ze-elektroniki, izixhobo ezichanekileyo, ishishini leekhemikhali, ishishini lokukhanya, ezothutho, izixhobo, i-aerospace, amandla e-athomu, njalo njalo, zibaluleke kakhulu kuqoqosho lwesizwe.
Ibhuloho egqunywe ngentsimbi eshushu(ibhuloho ye-zinc eshushu)
1, inkcazo ye-hot dip zinc:
I-hot dip zinc yenye yezona ndlela zibalaseleyo zokugquma ukukhusela i-substrate yentsimbi. Ikwimeko yolwelo ye-zinc, emva kokusebenza okuntsonkothileyo ngokwasemzimbeni nangokweekhemikhali, kungekuphela nje kumaleko we-zinc ococekileyo we-plating yentsimbi, kodwa ikwavelisa umaleko we-zinc-iron alloy. Le ndlela yokugquma ayinazo nje kuphela iimpawu zokuxhathisa ukugqwala kwe-galvanizing, kodwa ikwanayo nomaleko we-zinc-iron alloy. Ikwanayo nokuxhathisa ukugqwala okunamandla okungafaniswa ne-galvanizing. Ke ngoko, le ndlela yokugquma ifanelekile ngakumbi kuzo zonke iintlobo ze-asidi enamandla, inkungu ye-alkali kunye nezinye iindawo ezingqonge ukugqwala okunamandla.
2. Umgaqo:
Umaleko we-zinc oshushu wenziwa ngamanyathelo amathathu phantsi kolwelo olushushu kakhulu:
1) Umphezulu wesiseko sesinyithi unyibilikiswa sisicombululo se-zinc ukuze kwenziwe umaleko wesigaba se-zinc-iron alloy;
2) Ii-ion ze-zinc ezikumaleko we-alloy ziyasasazeka ngakumbi kwi-matrix ukuze zenze umaleko oxutywayo we-zinc-iron;
3) Umphezulu womaleko we-alloy ugquma umaleko we-zinc.
3. Iimpawu zokusebenza:
(1) Ngomaleko we-zinc oqinileyo nococekileyo ogqume umphezulu wentsimbi, ingayiphepha i-matrix yentsimbi kunye nayo nayiphi na i-corrosion solution contact, ikhusele i-matrix yentsimbi ekungcoleni. Kwi-atmosphere ngokubanzi, umphezulu womaleko we-zinc wenza umphezulu womaleko we-zinc oxide obhityileyo kakhulu noxineneyo, kunzima ukuwunyibilikisa emanzini, ngoko ke udlala indima ethile yokukhusela kwi-matrix yentsimbi. Ukuba i-zinc oxide kunye nezinye izinto ezikwi-atmosphere zenza ityuwa ye-zinc enganyibilikiyo, ukhuseleko lokungcola lungcono ngakumbi.
(2) Kukho umaleko we-iron-zinc alloy, oxineneyo, kwi-Marine salt spray atmosphere kunye ne-industrial atmosphere ukusebenza kwayo, ukumelana nokugqwala okungaqhelekanga;
(3) Ngenxa yokudibanisa okuqinileyo, i-zinc-iron iyaxutywa, kwaye inokumelana nokuguguleka okunamandla;
(4) Ngenxa yokuba i-zinc ine-ductility elungileyo, umaleko wayo we-alloy kunye nesiseko sentsimbi zinamathele ngokuqinileyo, ngoko ke iindawo zokugquma ezishushu zinokuba zi-cold stamping, rolling, drawing, golding kunye nezinye iintlobo ngaphandle kokonakalisa i-coating;
(5) Emva kokuntywiliselwa ngobushushu kwiindawo zesinyithi, kufana nonyango olunye lokutsalwa, olunokuphucula ngempumelelo iipropati zoomatshini ze-matrix yesinyithi, lususe uxinzelelo ngexesha lokwenziwa nokudityaniswa kweendawo zesinyithi, kwaye lunceda ekujikeni kweendawo zesinyithi.
(6) Umphezulu wezixhobo emva kokufakwa kwe-hot dip galvanizing ukhanya kwaye umhle.
(7) Umaleko we-zinc ococekileyo lolona maleko weplastiki kakhulu womaleko we-hot dip galvanized, iipropati zawo zisondele kakhulu kwi-zinc ecocekileyo, kwaye ziyakwazi ukuguquguquka.
4. Ububanzi besicelo:
Ukusetyenziswa kwe-hot dip galvanizing kuyanda ngophuhliso lweshishini kunye nezolimo. Ke ngoko, iimveliso ze-hot-dip galvanizing kushishino (ezifana nezixhobo zeekhemikhali, ukucubungula i-petroleum, uphando lwaselwandle, isakhiwo sesinyithi, ukuhanjiswa kwamandla, ukwakhiwa kweenqanawa, njl.njl.), ezolimo (ezifana nokunkcenkceshela, i-greenhouse), ulwakhiwo (ezifana nokudluliswa kwamanzi negesi, i-wire casing, i-scaffolding, izindlu, iiBridges, uthutho, njl.njl., ziye zasetyenziswa kakhulu kwiminyaka yakutshanje. Iimveliso ze-hot-dip galvaning zisetyenziswa kakhulu ngenxa yembonakalo yazo entle kunye nokumelana nokugqwala okuhle.
Okwesibini, umahluko phakathiibhulorho yokutshizakwayeibhulorho enesamente
Ibhulorho yokutshiza kunye nebhulorho ye-galvanized zahlukile kuphela kwinkqubo, iinkcukacha, iimodeli, imilo kunye nolwakhiwo lwebhulorho ziyafana.
Umahluko wenkqubo phakathi kwebhulorho yokutshiza kunye nebhulorho ye-galvanized:
Okokuqala,ibhulorho enesamentekwaye ibhulorho yokutshiza yeplastiki yeyebhulorho yentsimbi, ibhulorho eyenziwe ngentsimbi egalelweyo, ipleyiti yegalvanized ndikholelwa ukuba akukho mfuneko yokuchaza okuninzi, kwaye ibhulorho yokutshiza yeplastiki isetyenziselwa ukucubungula umaleko wokutshiza we-electrostatic kumphezulu webhulorho egalelweyo, ngoko ke ibizwa ngokuba yibhulorho yokutshiza yeplastiki, ukuqonda okulula kukuba ibhulorho yokutshiza yeplastiki yinguqulelo yophuculo yebhulorho egalelweyo, ukumelana nokugqwala kunamandla.
Ukuba unomdla kule mveliso, ungacofa kwikona esezantsi ngasekunene, siza kuqhagamshelana nawe ngokukhawuleza.
