Yintoni unyango olungaphezulu locingo olugoba olu-3d?

Yiyiphi indlela yonyango elungileyo kumphezulu we3d ukugoba ucingo? Ukutshiza iplastiki yindlela exhaphakileyo yonyango lomphezulu wocingo lokubiyela indawo yokugcina impahla. Ukutshiza iplastiki, ukungangcoliseki kokusingqongileyo, okungeyotyhefu kokusingqongileyo, okungeyotyhefu emzimbeni womntu, i-coating inomgangatho obalaseleyo wenkangeleko, ukunamathela okuqinileyo, amandla omatshini aphezulu, ixesha elifutshane lokunyanga, ubushushu obuphezulu kunye nokugquma okuxhathisayo, ukwakhiwa okulula, iimfuno zobugcisa zabasebenzi ziphantsi kakhulu, kwaye iindleko zingaphantsi kwenkqubo yokugquma.
Iplastiki efakwe ngaphakathi inokohlulwa ibe zizixhobo ezibini ezahlukeneyo eziluhlaza, ulwelo kunye nomgubo. Ubunzima bokugquma buphezulu kunolo lwenkqubo yokutshiza, kwaye ukuxhathisa ukubola kulungile. Ihlala isetyenziselwa unyango olungaphezulu kocingo lwangaphandle lwegumbi.

I-Hot-dip galvanizing yindlela esebenzayo yokuthintela ukubola kwesinyithi. Kukumanzisa isisombululo se-zinc esityhidiweyo senxalenye yentsimbi emva kokususwa komhlwa malunga ne-500 degrees Celsius, ngoko isakhiwo sensimbi kunye ne-zinc layer phezu komhlaba, ngoko injongo ye-anti-corrosion. I-Hot-dip galvanizing ineengenelo zokugquma kwe-zinc eshinyeneyo, ixesha elide lokuxhathisa ityuwa kunye nokuxhathisa okuqinileyo ku-corrosion. Isetyenziswa ngokubanzi ekuxhathiseni ukubola kwezixhobo zamashishini, ezinje ngonyango lomphezulu lweebhulorho zentambo, iinqaba zokuhambisa amandla, kunye neebhulorho zentsimbi. Ukumelana nomhlwa kwe-hot-dip galvanizing iphezulu kakhulu kunaleyo ye-galvanizing yediphu ebandayo.
Ukugquma okubandayo kukwabizwa ngokuba yigalvanizing. Isebenzisa izixhobo ze-electrolysis ukususa i-oyile, i-pickling, kwaye emva koko ifakwe kwisisombululo setyuwa ye-zinc, kwaye idibanise i-electrode engalunganga yezixhobo ze-electrolysis. Ipleyiti ye-zinc ibekwe kwelinye icala lombhobho kwaye ixhunywe kwi-cathode yesixhobo se-electrolysis. Ukuhamba kwangoku ukusuka kwi-electrode echanekileyo ukuya kwi-electrode engalunganga iya kutshona phezulu nangaphantsi kumbhobho. Uluhlu lwe-zinc lufakwe, unyango lombhobho obandayo kunye ne-galvanized.
3d ukugoba ucingoindlela unyango umphezulu Le ndlela ibandakanya degreasing alkaline, ukuhlamba amanzi acocekileyo, ukuhlamba acid, ukuhlamba amanzi ashushu, cathode degreasing, imichiza degreasing, activation acid kunye nezinye iinkqubo ezahlukeneyo.
