Uthelekiso kunye noMahluko phakathi kwe-ASTM A153 kunye ne-ASTM A123 i-Hot Dip Galvanizing Standards.

I-Hot dip galvanizing yinkqubo eqhelekileyo yensimbi yokulwa ne-corrosion esetyenziswa ngokubanzi kwiimveliso zetsimbi ukwandisa ubomi babo benkonzo kunye nokubonelela ngokhuseleko olungcono. I-ASTM (i-American Society for Testing and Materials) iphuhlise imigangatho emininzi yokumisela iinkqubo kunye neemfuno ze-galvanizing ye-hot-dip, kunye ne-ASTM A153 kunye ne-ASTM A123 yimigangatho emibini ephambili. Oku kulandelayo luthelekiso kunye nomahluko phakathi kwale migangatho mibini:

I-ASTM A153:

I-ASTM A153ngumgangatho oshushu-dip galvanized steel hardware. Lo mgangatho uhlala usebenza kwiindawo ezincinci zentsimbi, ezinje ngeebholiti, iinati, izikhonkwane, izikrufu,iingqiniba,izinciphisi, njl.

1. Ubungakanani besicelo: Idiphu eshushu yokufaka igalvanizing yeendawo ezincinci zetsimbi.

2. Ubukhulu be-zinc layer: Ngokuqhelekileyo, ubuncinci be-zinc layer iyafuneka. Ngokuqhelekileyo i-galvanized lightweight, inika ukuxhathisa okulungileyo kokuhlwa.

3. Intsimi yesicelo: Ngokuqhelekileyo isetyenziswe kwiindawo zangaphakathi kunye neemfuneko eziphantsi zokumelana nokubola, njengefenitshala, iingcingo, i-hardware yendlu, njl.

4. Iimfuno zobushushu: Kukho imimiselo yokushisa okushushu kwediphu yezinto ezahlukeneyo.

I-ASTM A123:

Ngokungafaniyo ne-ASTM A153, umgangatho we-ASTM A123 uyasebenza kumacandelo amakhulu olwakhiwo,imibhobho yentsimbi, iintsimbi zentsimbi, njl.

1. Umda wesicelo: Ufanelekile kumacandelo amakhulu okwakhiwa, njengamacandelo ensimbi, iibhuloho, iipayipi, njl.

2. Umaleko we-zinc ubukhulu: Kukho ubuncinci obuphezulu bemfuno yomaleko we-zinc ogqunyiweyo, odla ngokubonelela nge-zinc etyebileyo yokwaleka ukunika ukhuseleko olunamandla.

3. Intsimi yokusetyenziswa: Ngokuqhelekileyo isetyenziselwa izakhiwo zangaphandle kunye neendawo ezicacileyo kwiindawo ezinzima, ezifana neebhuloho, iipayipi, izixhobo zangaphandle, njl.

4. Ukuqina: Ngenxa yokubandakanyeka kwamacandelo abaluleke ngakumbi okwakhiwa, i-galvanized layer iyafuneka ukuze imelane namaxesha amade okuhlwa kunye nokukhukuliseka kwendalo.

Uthelekiso kunye noShwankathelo:

1. Uluhlu lwezicelo ezahlukeneyo: I-A153 ifanelekile kumacandelo amancinci, ngelixa i-A123 ifanelekile kumacandelo amakhulu okwakhiwa.

2. Ubunzima kunye nokuqina kwe-zinc layer yahlukile: I-A123's yokugqoka i-zinc inzima kwaye ihlala ihlala njalo, inika iqondo eliphezulu lokukhusela.

3. Iinkalo ezahlukeneyo zokusetyenziswa: I-A153 isetyenziswa ngokuqhelekileyo kwiindawo zangaphakathi kunye neendawo eziphantsi kwe-corrosion, ngelixa i-A123 ifanelekile kwiindawo ezingaphandle kunye neziphezulu.

4. Iimfuno zobushushu kunye nenkqubo eyahlukileyo kancinane: Le migangatho mibini ineqondo layo lobushushu lediphu kunye neemfuno zenkqubo yeesayizi ezahlukeneyo kunye neentlobo zezinto.

Ngokubanzi, umahluko phakathi kwe-ASTM A153 kunye ne-ASTM A123 ikakhulu ulele kububanzi besicelo, ubukhulu be-zinc layer, indawo yokusetyenziswa, kunye neemfuno zokuqina. Ngokweemeko ezithile zokusetyenziswa kunye neemfuno, abavelisi kunye neenjineli kufuneka bakhethe imigangatho ehlangabezana neemfuno ezihambelanayo zokuqinisekisa umgangatho wemveliso kunye nokuqina.
