Umahluko phakathi kombhobho wentsimbi ogqunywe nge-galvanized pre-galvanized kunye nombhobho wentsimbi oshushu, ungawujonga njani umgangatho wawo?

Umahluko phakathiumbhobho ofakwe i-galvanized kwangaphambilikwayeUmbhobho weNtsimbi oshushu ofakwe kwi-DIP

1. Umahluko kwinkqubo: Umbhobho we-galvanized oshushu ugqunywa ngokuntywilisela umbhobho wentsimbi kwi-zinc enyibilikisiweyo, ngelixaumbhobho ofakwe i-galvanized kwangaphambiliigqunywe ngokulinganayo nge-zinc kumphezulu wentsimbi ngenkqubo ye-electroplating.

2. Umahluko kwisakhiwo: Umbhobho we-galvanized oshushu yimveliso yetyhubhu, ngelixa umbhobho wentsimbi osele ugqityiweyo yimveliso yestrip enobubanzi obukhulu kunye nobukhulu obuncinci.

3. Iindlela ezahlukeneyo zokusetyenziswa: Iipayipi ezishushu ezigqunyiweyo zisetyenziselwa kakhulu ukuthutha ulwelo kunye neegesi, ezifana neepayipi zokuhambisa amanzi, iipayipi zeoyile, njl.njl., ngelixa iipayipi zentsimbi ezigqunyiweyo zisetyenziselwa kakhulu ukuvelisa iimveliso ezahlukeneyo zesinyithi, ezifana nezixhobo zeemoto, amaqokobhe ezixhobo zasekhaya njalo njalo.

4. Ukusebenza okwahlukileyo kokulwa nokugqwala: umbhobho we-galvanized oshushu oditywayo unamandla okulwa nokugqwala ngenxa yomaleko we-galvanized otyebileyo, ngelixa umcu wentsimbi we-galvanized unamandla okulwa nokugqwala ngenxa yomaleko we-galvanized obhityileyo.

5. Iindleko ezahlukeneyo: inkqubo yokuvelisa umbhobho we-galvanized oshushu iyinkimbinkimbi kwaye ibiza kakhulu, ngelixa inkqubo yokuvelisa umbhobho wentsimbi we-galvanized ilula kwaye ixabisa kancinci.

Ukuhlolwa komgangatho wombhobho wentsimbi ogqunywe nge-galvanized kunye ne-hot-dip
1. Ukuhlolwa kwenkangeleko
Ukugqitywa komphezulu: Ukuhlolwa kwenkangeleko kuxhomekeke kakhulu ekubeni umphezulu wombhobho wentsimbi uthe tyaba kwaye ugudile na, ngaphandle kwe-zinc slag ecacileyo, i-zinc tumor, ukuxhoma kokuhamba kwamanzi okanye ezinye iziphene zomphezulu. Umphezulu wombhobho wentsimbi oqinisiweyo olungileyo kufuneka ube bushelelezi, kungabikho maqamza, kungabikho mifantu, kungabikho zithumba ze-zinc okanye ukuxhoma kokuhamba kwamanzi kunye nezinye iziphene.

Umbala kunye nokufana: Jonga ukuba umbala wombhobho wentsimbi uyafana kwaye uhambelana, kwaye akukho mahluko angalinganiyo kumaleko we-zinc, ingakumbi kwiindawo ezidityanisiweyo okanye kwiindawo ezidityanisiweyo. Umbhobho wentsimbi egqunyiweyo eshushu ngokubanzi ubonakala umhlophe njengesilivere okanye umhlophe, ngelixa umbhobho wentsimbi ogqunyiweyo ngaphambili unokuba nombala okhanyayo kancinci.

2. Umlinganiselo wobukhulu beZinc
Igeyiji yoBungqingqwa: Ubukhulu bomaleko we-zinc bulinganiswa kusetyenziswa igeyiji yobukhulu obugqunywe nge-coated (umz. i-magnetic okanye i-eddy current). Olu luphawu oluphambili lokumisela ukuba i-zinc coating iyahlangabezana neemfuno ezisemgangathweni. Umbhobho wentsimbi egqunywe nge-hot-dip uhlala unomaleko we-zinc ongqindilili, oqhele ukuba phakathi kwe-60-120 microns, kwaye umbhobho wentsimbi ogqunywe nge-pre-galvanized unomaleko we-zinc ongqindilili, oqhele ukuba phakathi kwe-15-30 microns.

Indlela yobunzima (iisampulu): Iisampuli zilinganiswa ngokwemigangatho kwaye ubunzima beleyara ye-zinc kwindawo nganye yeyunithi bubalwa ukuze kuchongwe ubukhulu beleyara ye-zinc. Oku kudla ngokugqitywa ngokulinganisa ubunzima bepayipi emva kokuyikha.

Iimfuneko ezisemgangathweni: Umzekelo, i-GB/T 13912, i-ASTM A123 kunye neminye imigangatho ineemfuno ezicacileyo zobukhulu bomaleko we-zinc, kwaye iimfuno zobukhulu bomaleko we-zinc kwiipayipi zentsimbi kwizicelo ezahlukeneyo zinokwahluka.

3. Ukufana komaleko we-galvanized
Umaleko we-galvanized osemgangathweni ophezulu ufana ngobume, akukho kuvuza kwaye akukho monakalo kwi-post plating.

Akukho mphunga ubomvu ufunyenweyo emva kokuvavanywa ngesisombululo se-copper sulfate, nto leyo ebonisa ukuba akukho kuvuza okanye umonakalo emva kokufakwa kweplati.

Lo ngumgangatho wezixhobo ze-galvanized ezikumgangatho ophezulu ukuqinisekisa ukusebenza kakuhle kunye nenkangeleko efanelekileyo.

4. Ukunamathela okuqinileyo komaleko we-galvanized
Ukunamathela komaleko we-galvanized luphawu olubalulekileyo lomgangatho wombhobho wentsimbi ye-galvanized, olubonisa ubungakanani bokuqina komxube phakathi komaleko we-galvanized kunye nombhobho wentsimbi.

Umbhobho wentsimbi uza kwenza umaleko oxutyiweyo we-zinc kunye ne-iron kunye nesisombululo se-galvanizing emva kokusabela kwebhafu yokuntywila, kwaye ukunamathela komaleko we-zinc kunokuphuculwa yinkqubo yesayensi nechanekileyo ye-galvanizing.

Ukuba umaleko we-zinc awuphumi lula xa ucofwa ngesando serabha, oko kubonisa ukunamathelana okuhle.
