Uyini umehluko phakathi kwe-Dacromet ne-hot dip galvanizing?

I-Dacromet kanye ne-hot-dip galvanizing zombili izindlela ezivame ukusetshenziswa ze-electroplating, ngakho-ke yini umehluko phakathi kwazo? Vumela umhleli afunde ngakho nawe namuhla.

1. Izithako ezihlukene:

I-Dacromet ikakhulukazi iqukethe i-zinc powder, i-aluminium powder, i-chromic acid namanzi angenalutho;

I-hot-dip galvanizing ukucwilisa izinsimbi ezifana nensimbi, insimbi engagqwali, kanye nensimbi ejikijelwe ensimbi encibilikisiwe yoketshezi noma ama-alloys.

2. Izimiso zihlukile:

I-Dacromet ibangelwa izingqimba ezigqagqene ze-flake zinc kanye ne-aluminium, evimbela inqubo yemidiya egqwalayo efana namanzi nomoya-mpilo ofinyelela ku-substrate, futhi ingenza njengomphumela wokuvikela ozimele;

I-hot-dip galvanizing iyindlela yokucwilisa izingxenye zensimbi ku-zinc encibilikisiwe ukuze kutholwe ukunamathela kwensimbi.

3. Izinhlelo zokusebenza ezehlukene:

I-hot-dip galvanizing isetshenziswa kakhulu emibhoshongweni kagesi, emibhoshongweni yokuxhumana, ezitimeleni, ekuvikelweni komgwaqo onguthelawayeka, izigxobo zezibani zasemgwaqweni, izikhungo ezihambisana nesiteshi esincane, imboni yokukhanya, njll.;

I-Dacromet isetshenziselwa ikakhulukazi ukulwa nokugqwala kwezingxenye ezihlukahlukene zokunwebeka emalolini kanye nokunqanda ukugqwala kwezingxenye zensimbi ezindaweni ezishisa kakhulu njengezinjini.

4. Ngokwesikhathi sokufutha usawoti, isikhathi sokuhlola ukumelana nosawoti ka-Dacromet side kakhulu, kodwa ukuhlolwa kusendaweni engathathi hlangothi; mayelana nemvelo yangaphandle yomoya, i-hot-dip galvanizing inekhono elingcono lokulwa nokugqwala.

Ngaphezu kwalokho, i-hot-dip galvanized coating iwugqinsi futhi ibukeka ilukhuni, kodwa inokunamathela okuhle futhi ukwelashwa kwendawo kungamelana namazinga okushisa aphezulu;

I-Dacromet inombala omncane nokubukeka okukhanyayo, kodwa ukwelashwa okungaphezulu akukwazi ukumelana namazinga okushisa aphezulu.

I-hot-dip galvanizing, ebizwa nangokuthi i-hot-dip galvanizing kanye ne-hot-dip galvanizing: kuyindlela ephumelelayo yokunqanda ukugqwala kwensimbi futhi isetshenziselwa ikakhulukazi izakhiwo zensimbi ezimbonini ezihlukahlukene. Kuwukucwilisa izingxenye zensimbi ezikhishwe ukugqwala oketshezini lwezinki oluncibilikisiwe cishe cishe ku-500 ° C, ukuze ungqimba lwe-zinc lunamathele ebusweni bezingxenye zensimbi, ngaleyo ndlela kufezeke injongo yokulwa nokugqwala.

Ukugeleza kwenqubo yokufaka i-galvanizing yediphu eshisayo: ukukha imikhiqizo eqediwe - ukugeza amanzi - ukwengeza isixazululo sokucwenga - ukomisa - ukufakwa kwama-rack - ukupholisa - ukwelashwa ngamakhemikhali - ukuhlanza - ukupholisha - ukucwenga kwediphu okushisayo kuqediwe.

I-hot-dip galvanizing yasungulwa kusukela endleleni yakudala ye-hot-dip. Njengoba iFrance yafaka ugesi oshisayo embonini ngo-1836, inomlando weminyaka engaphezu kuka-170.

I-Dacromet ukuguqulwa kwamaletha nesifinyezo se-DACROMET, esifushanisiwe njenge-Dacromet, i-Dacromet, ne-Dickron. Igcokama lasekhaya eliqanjwe nge-chrome, wuhlobo olusha lwe-anti-corrosion coating izingxenye zalo eziyinhloko okuyimpushana ye-zinc, i-aluminium powder, i-chromic acid namanzi akhishwe yi-deionized.

Ukugeleza kwenqubo ye-Dacromet: i-organic solvent degreasing--mechanical polishing--spraying--baking--secondary spraying--baking--drying
