Nayiphi na intsimbi evezwe emoyeni ixesha elide ithande ukuba oxidize ekuhambeni kwexesha. Emva kweminyaka yamava aqinisekisiweyo, iFasteners Engineering iye yaphuhlisa kwaye yaphuhlisa uluhlu lwezonyango ezikwaziyo ukusombulula ingxaki ye-oxidation kwiibholithi. Apha ngezantsi sidwelisa iinkqubo ezahlukeneyo zokuvelisa ezisetyenziswayo kunye nohlengahlengiso ngokwesiseko seemfuno zabathengi bethu.

Njengenye yezinto zokuqinisa ezibalulekileyo, izikrufu ngokubanzi zisebenzisa iinkqubo ezahlukeneyo zonyango lomphezulu ukuhlangabezana neemfuno zabathengi. Ndiyathemba ukuba olu lwazi lulandelayo luya kuba luncedo kuwe.

1. Ukufakwa kweZinc.

Ukufakwa kwegalvanizing kunokohlulwa ibe yigalvanizing ebandayo, igalvanizing yomatshini kunye ne-galvanizing eshushu, apho i-galvanizing eshushu ithandwa kakhulu. Ukutshisa igalvanizing, okwakwaziwa njenge hot-dip galvanizing, kukuntywilisela amalungu entsimbi asuswe umhlwa kwisinyibiliko se zinc esimalunga ne 500℃. Ngale ndlela, umphezulu we-workpiece ufakwe kwi-zinc layer, esebenza ngenjongo yokuchasana nokubola. Uncedo lokugalela idiphu eshushu ngolu hlobo lulandelayo:

• Isakhono esinamandla sokuchasa umhlwa.
• Ukubambelela okungcono kunye nobunzima bomgca we-galvanized.
• Ubungakanani be-zinc bukhulu, kwaye ubukhulu be-zinc layer ngamaxesha amaninzi okubanda okubandayo.
• Ixabiso eliphantsi kwaye lihambelana nokusingqongileyo.

2.I-Phosphating yomhlaba.

I-Surface phosphating lunyango oluphantsi kakhulu olusetyenziswa njenge-primer phambi kokupeyinta.

• Injongo ephambili kukubonelela ngokhuseleko kwintsimbi kunye nokukhusela isinyithi ukuba singabikho kumlinganiselo othile.
• Ukuphucula ukubambelela kwifilimu yepeyinti.
• Ukunciphisa ukukhuhla kunye nokuthambisa ngexesha lokusebenza kwentsimbi ebandayo.

I-3.Dacromet luhlobo olutsha lwe-anti-corrosion coating, eyona teknoloji ingcono kakhulu yokubuyisela i-electro-galvanizing yendabuko kunye ne-hot-dip galvanizing enokungcola okunzulu kokusingqongileyo. Iinzuzo zayo zezi zilandelayo:

• Ukumelana nokugqwesa okuphezulu: impembelelo yokumelana nomhlwa ngamaxesha angama-7-10 aphezulu kune-galvanizing yendabuko.
• Ayikho i-hydrogen embrittlement phenomenon, efanelekile kakhulu ukugquma iindawo ezigxininisiweyo.
• Ukumelana nobushushu obuphezulu, ubushushu bokumelana nobushushu bunokufikelela ngaphezulu kwe-300 ℃.
• Ukubambelela okuhle kunye nokusebenza kwakhona
• Akukho manzi amdaka kunye negesi eyinkunkuma iya kuveliswa ngexesha lenkqubo yokuvelisa.

4. Umbungu

I-Ruspert luhlobo lokwaleka olwaqaliswa kwizikrufu zokwakha, i-coating ehambelana nokusingqongileyo ephuhliswe emva kweDacromet. Xa kuthelekiswa neDacromet, iingenelo zeruspert zimi ngolu hlobo lulandelayo:

• Ukumelana nokugqwala okunamandla, kunokumelana novavanyo lokutshiza ngetyuwa kwiiyure ezingama-500-1500
• Ukwaleka nzima
• Ukugqiba umgangatho ongcono kunye nokubambelela
• Imibala emininzi ekhoyo

I-DD Fasteners ineminyaka engama-20 yokuvelisa i-fastener kunye namava okuthengisa.

Ukuba unazo naziphi na iimfuno zesikrufu, nceda uqhagamshelane nathi, siya kukukhonza ngentliziyo epheleleyo.
