I-ASTM A179umbhobho wentsimbi epholileyo otsalweyoisetyenziswa ikakhulu kumacandelo ahlukeneyo okwakhiwa kwezakhiwo zesinyithi, ngakumbi emva kokugqwala kwamaqhekeza entsimbi antywiliselwe kwi-440 ~ 460.℃isisombululo se-zinc esinyibilikayo, ukwenzela ukuba indawo yentsimbi ifakwe kwi-zinc layer, edlala injongo yokulondoloza.Le yindlela esebenzayo yokubola kwesinyithi, ukusetyenziswa kweempawu eziphambili zezi zilandelayo:

(1) I-ASTM A179 ebandayo abavelisi bemibhobho engenamthungo onomaleko oshinyeneyo oshinyeneyo we-zinki ogqunywe kumphezulu wetyhubhu otsalwa ngokubanda ongenamthungo, unokunqanda imatriksi yetyhubhu etsalwa ngokubanda engenamthungo kunye naluphi na unxibelelwano nesisombululo somhlwa ukukhusela imatrix yentsimbi ekudlekeni.Kwi-atmosphere jikelele, umphezulu we-zinc layer ukwenza umaleko we-zinc oxide obhityileyo kwaye oxineneyo, kunzima ukunyibilika emanzini, ngoko ke i-matrix yensimbi idlala indima yokukhusela.Ukuba i-zinc oxide kunye namanye amacandelo omoya avelisa ityuwa ye-zinc enganyibilikiyo, i-anti-corrosion effect ifunwa kakhulu.

(2) Ngentsimbi - i-zinc alloy layer, idibene ne-dense, kunye ne-anti-corrosion ekhethekileyo kwi-atmosphere yolwandle kunye ne-atmospheric atmosphere.

(3) I-ASTM A179 ebandayo itsalwa umbhobho ongenamthungo kunye nokunganyangeki okuqinileyo ngenxa yokudibanisa okuqinileyo, i-zinc - intsimbi edibeneyo.

(4) Ekubeni i-zinc ine-ductility efanelekileyo, i-alloy layer kunye nesiseko sentsimbi eqhotyoshelwe kwisiqina, ngoko ke iindawo ezishushu ezishushu zinokubanda, ziqengqeleke, zizoba, zigobe kunye nokunye ukubumba ngaphandle komonakalo wokugquma.

(5) I-Hot-dip galvanized galvanized steel structural pipe, elingana nonyango lwe-annealing, inokuphucula ngokufanelekileyo iimpawu zomatshini ze-matrix yensimbi ukuphelisa uxinzelelo lwentsimbi yokwenza i-welding, ihambelana nesakhiwo sentsimbi yokujika.

(6) Umphezulu wombhobho otsalwa ngokubanda ongenamthungo emva kwegalvanized eshushu uyaqaqamba kwaye mhle.

(7) Umaleko we-zinc ococekileyo ngowona maleko ashushu kakhulu wegalvanized layer, indalo yawo ngokusisiseko isondele kwi-zinc ecocekileyo, kunye ne-ductility, ngoko igcwele ukuguquguquka.
