Galvanizing metal ngezandla zabo: yeendlela eziphambili

iimveliso Metal ngexesha lomsebenzi ezinokudla. Njengoko nokukhuseleka zinc wire metal. obu bugcisa unyango ekhaya iyafikeleleka kakhulu. Kubalulekile ukuba ukhethe ukhetho unyango ekunene.

Yini galvanizing

Zonke iindawo metal zibethwa namaqondo yeenkqubo entsimbini. Ukwenza ngaphandle. Kwaye le nkqubo singamiswa kuphela. Nale njongo, kwaye usebenzisa unyango kunye zinc. Le ukhetho ezibonakalayo akuyona ngengozi. Ukukhetha kwenziwa ngokususela iimpawu macandelo mabini: i zentsimbi kunye zinc. Izinki omela electronegative ngakumbi, kunokuba kwensimbi. Xa isicelo iimveliso metal zinc ukutyabeka kuyilwa nokuhlangana galvanic phakathi intsimbi kunye zinc. Ngale ndlela, phantsi kwempembelelo yeemeko zangaphandle, kokugquma waphendula a zinc. ekudibaneni kwemichiza kunye inxaxheba ngentsimbi lancipha. Kwaye ngoko ke kuya kuqhubeka ukuba logama nje ukutyabeka zinc lutshatyalaliswe ngokupheleleyo.

Kwiimeko apho ukutyabeka nezinki waphula phantsi, ukuziphendulela iyaqhubeka ukusebenza. Oku kungenxa yokuba zinc idityaniswe oksijini emoyeni. Ngenxa yeenkqubo imichiza zinc hayidroksayidi kwakheka. A into esiyinikwe anazo iipropati zokuzikhusela. Ngenxa yoko, metal kwalenza iyaqhubeka ukusebenza.

tindlela galvanizing

Galvanizing iimveliso but is ndlela ithandwa kakhulu ukujongana umhlwa. Oku kungenxa umlinganiselo ophezulu ngenxa yokuba uvavanyo kunye nexabiso nezifikelelekayo. Ezi ndlela zilandelayo zisetyenziswa metal kwalenza:

• ebandayo;
• hot;
• galvanic;
• thermodiffusion;
• spray emhlabeni.

Ukukhetha le ndlela ifanelekileyo, kufuneka kuqala ukuhlalutya iimeko apho imveliso iza kusetyenziswa kwixesha elizayo. kwizinga Galvanizing kuxhomekeke Ebubanzini ukutyabeka, ixesha kunye nokukhuselwa lobushushu. Galvanizing metal ngezandla zabo kuphela kunokwenzeka ngeendlela ezimbini: ebandayo ngumfanekiswana. Kubalulekile ukuphawula ukuba phakade iindawo ezinjalo ngayo iya kuxhomekeka kwimeko yokusebenza le. Umaleko zinc lulula phantsi umothuko ngoomatshini.

fashion hot

galvanizing Hot ngentsimbi yeyona practical ukhetho. wezenzi imveliso yemichiza esetyenziselwa unyango ephindwe. Bona walungisa ngokusebenzisa ezingundoqo yenkcenkce nkqubo. Kungenxa yoko kukho ingxaki yokusingqongileyo. I-zinc eyandisiweyo esetyenziselwa le nkqubo. Le mveliso uzilungiselele nkxu nje ibe webhate zinc otyhidiweyo.

izixhobo ngokukhethekileyo kule nkqubo. Ngoko ke, le ndlela ayikho ezifanelekileyo metal kwalenza ekhaya.

indlela nokuhanjiswa thermal

metal Isefu yi le nkqubo ibandakanya kwii-athom zinc kwi isakhiwo imveliso metal zenze yentsimbi-zinc ingxubevange kunye nesakhiwo ezintsonkothileyo. yonke le nkqubo ithabatha indawo kwiqondo lobushushu eliphezulu kakhulu. Kubushushu kwama-2600 izidanga nezinki ludlulele kurhulumente sukube. azicenge, apho iimveliso yesinyithi, ezele umgubo zinc aqulethe. indlela efanelekileyo isicelo umaleko, ogama ubukhulu lidlula micrometers-15. kwisiphumo ukutyabeka zokhuselo iyawulwa onokufaniswa umaleko isicelo yi eshushu. Ngenxa yemfuneko ukudala iimeko ezithile akafanelanga kusetyenziselwa self-zokuqonda.

indlela Gas-thermal

Kule ndlela, zinc, leyo ngokohlobo powder, ukuhamba umoya kutshizwa phezu iimveliso zesinyithi. Phambi kokuba izinto zaphela yi amaqondo obushushu aphezulu kwaye kule meko wokutshiza uvikivwa ngokwenkcukacha. metal Galvanizing luphawulwa ngendlela efanayo nezo meko apho iimveliso zesinyithi babe ubukhulu enkulu.

Uphawu le ndlela kukuba umaleko yokhuselo has a lot of pores. Ukugcwalisa imveliso yazo ligutyungelwe ipeyinti. Lo maleko ezimbini engumxube nako igcinwe kangangeminyaka engama-30. Le ndlela akunakuzalisekiswa kweli khaya.

galvanizing Cold ekhaya

Kukho kwakhona kubanda galvanizing. Isefu metal indlela elinjalo isicelo ukuya kwimveliso zinc sisinyithi ngohlobo yepeyinti. Abavelisi abonelele ngeenkalo ezininzi kwezi mali. Kunye core yokwenza (umz, zinc ubunzima iqhezu kwi material) nga kwahluka kakhulu omnye komnye. Kucaca ukuba ifuthe unyango nazo ziya kwahluka.

Kuthetha ukuba galvanizing eziliqela iimpawu. Ezinye zifuna umgangatho ophezulu iimveliso zoqeqesho. Igosa elingumvi oyintloko ukuba unobuchule adhesion ephantsi, ngenxa emva kokuqala iyoma ukuba flake. Kanti abanye ivalwe emva kokuba isicelo "Umsonto" avela neentanda. Okwesine unako ukusebenza ngokudibene kuphela nohlobo izinyibilikisi ezithile. Okwesihlanu kufuna isicelo kwezixhobo ezizodwa.

Esi sixhobo i binary. Ngoko ke, ngaphambi kokuba isicelo izinto ezimbini (luthuthu Umatshini) kufuneka ugalelwe kunye nabanye. Yenza oku umlinganiselo we-3 ukuya-1 okanye 1 ukuya 1. lonke Inkqubo kufuneka luqhutywe kuphela phantsi kweemeko ezithile. Kufuneka ubushushu emoyeni vumelanayo kwaye kuluhlu ukusuka izidanga-5 ukuya kuma-40. Kulo ukufuma tyala ukususela-30 ukuya 98%. Igumbi apho inkqubo kufuneka abe umoya olungileyo. Emva emsebenzini, kufuneka ngocoselelo lidlale. Arhente lisetyenziswa ngokwemaleko ezimbini kudluliswe malunga nemizuzu engama-30. Emva kosuku olunye, imveliso nokuba isale kokwakheka paint. Ngexesha galvanizing kuyimfuneko ukuba uyigcine imithetho yokhuseleko. Wonke umsebenzi wenziwa kunye nokusetyenziswa kwezixhobo zokuzikhusela zobuqu.

Indlela electroplating

metal Isefu ekhaya na kwenziwa electroplating. Kuba le mveliso yokuqala ukuba ucocwe. Emva koko, into lihla imizuzwana embalwa (2 ukuya ku-10), e-sulphuric acid. Emva koko, lo imveliso akuhlanjwanga ngamanzi. Kulo Ukulungiselela le anodization sele kugqityiwe. Kuba ukufakwa phantsi galvanizing izitya kufuneka zikhethwe ngezinto egalelwe, umz, iglasi. Tara olukhethiweyo kwi ngendlela yokuba yokuhlala ku iinkcukacha kunye electrode eziqhotyoshelwe kuyo.

umthombo yangoku itshaja yi 6-12 kwaye 2-6 A. In olunye electrolyte uzilungiselele - isisombululo nawuphi ityuwa, unyityilikiswa emanzini. Nto ithetha ukuba, kungcono ukuthatha ityuwa zinc. Unako ukuthatha sulphuric acid yaze yangxenga ifuthe lomanyano (as in ibhetri) kwaye udibanise zinc. Ngenxa ekudibaneni kwemichiza similise netyuwa asidi ezingenakunyibilika kunye ehlele. A zinc ahlale isisombululo. Le kwenze kufuneka zisuswe, izicoci nje isicombululo.

Izinki electrode wenziwa isiziba zinc inkxaso kwi-wire yobhedu. Ukususela "thabatha" ibhetri itshaja nakwesiphi na workpiece, yaye "dibanisa" - to zinc. Ngoko ke, i electrode izinc iyapheliswa kwaye zonke athom nezinki ezilalisa workpiece.

isiphelo

metal galvanizing ekhaya - yinkqubo wokwenene. Kuba ukuphunyezwa kwayo kuya kufuneka ukuba bathenge ezinye izinto. Ngokomzekelo, omnye ipeyinti zinc-based okanye inkqubo abandayo electroplating isiqwenga zinc. Ke kaloku, zinc zingathengwa kuyo nayiphi na indawo ngeentsimbi ezindala.
