Umahluko phakathi kombhobho wentsimbi ofakwe ngaphambili kunye neshushu-dip, ukujonga njani umgangatho wayo?

Umahluko phakathiumbhobho wangaphambilikwayeUmbhobho weNtsimbi oshushu-DIP

1. Umahluko kwinkqubo: Umbhobho wegalvanized wediphu oshushu ufakwa igalvan ngokuntywiliselwa umbhobho wentsimbi kwizinc etyhidiweyo, ngelixa.umbhobho wangaphambiliifakwe ngokulinganayo nge-zinc kumphezulu wentsimbi yentsimbi ngenkqubo ye-electroplating.

2. Umahluko wesakhiwo: Umbhobho otshisiweyo oshushu yimveliso ye-tubular, ngelixa umbhobho wentsimbi wangaphambili uyimveliso yoluhlu olunobubanzi obukhulu kunye nobukhulu obuncinci.

3. Usetyenziso olwahlukileyo: Imibhobho eshushu yamanzi isetyenziselwa ukuthutha ulwelo kunye neegesi, njengemibhobho yonikezelo lwamanzi, imibhobho yeoli, njl.njl., ngelixa imibhobho yentsimbi yangaphambili isetyenziselwa ukwenza iimveliso ezahlukeneyo zentsimbi, ezinje ngeendawo zemoto, ekhaya. amaqokobhe esixhobo njalo njalo.

4. Ukusebenza okwahlukileyo kokuchasana nomhlwa: umbhobho owenziwe yizinki oshushu-dip unomsebenzi ongcono wokuchasa umhlwa ngenxa yomaleko ongqindilili wegalvanized, lo gama umcu wentsimbi owenziwe ngesinyithi usebenza kakubi ngokwentelekiso wokuchasa umhlwa ngenxa yomaleko obhityileyo wegalvanized.

5. Iindleko ezahlukeneyo: inkqubo yokuvelisa umbhobho we-galvanized we-hot-dip inzima kwaye ibiza kakhulu, ngelixa inkqubo yokuvelisa umbhobho wensimbi yensimbi ilula kwaye iphantsi.

Ukuhlolwa komgangatho wombhobho wentsimbi owenziwe ngamagalvanized pre-galvanized and hot-dip
1. Ukuhlolwa kwembonakalo
Ukugqitywa komphezulu: Ukuhlolwa kwembonakalo kuxhomekeke ikakhulu malunga nokuba umphezulu wombhobho wensimbi usicaba kwaye ugudileyo, ngaphandle kwe-zinc slag ecacileyo, i-tumor ye-zinc, ukuhamba okujingayo okanye ezinye iziphene zomhlaba. Umphezulu wemibhobho yentsimbi egudileyo kufuneka ugudiswe, kungabikho amaqamza, kungabikho zintanda, kungabikho zinc tumors okanye zinc flow ejingayo kunye nezinye iziphene.

Umbala kunye nokufana: Khangela ukuba umbala wombhobho wensimbi ufana kwaye uhambelana, kwaye ingaba kukho ukusabalalisa okungalinganiyo kwe-zinc layer, ngokukodwa kwi-seams okanye kwiindawo ezidibeneyo. Umbhobho wentsimbi owenziwe ngesinyithi oshushu-diphu ubonakala umhlophe ngokwesilivere okanye ungekho mhlophe, ngelixa umbhobho wentsimbi wangaphambili unokuba khaphukhaphu kancinci ngombala.

2. Umlinganiselo wobukhulu beZinc
Igeyiji yokutyeba: Ubukhulu bomaleko we-zinc bulinganiswa kusetyenziswa igeyiji yobukhulu obugqunyiweyo (umzekelo: imagnethi okanye i-eddi current). Esi sisilathisi esibalulekileyo sokugqiba ukuba i-zinc coating ihlangabezana neemfuno eziqhelekileyo. Umbhobho wentsimbi owenziwe ngamazinki ashushu udla ngokuba nongqimba olungqindilili lwezinki, phakathi kwe-60-120 yemicrons, kwaye umbhobho wentsimbi wangaphambili unomaleko obhityileyo we-zinc, ophakathi kwe-15-30 yemicrons.

Indlela yobunzima (iisampulu): Iisampulu zilinganiswe ngokwemigangatho kwaye ubunzima bomgangatho we-zinc kwindawo nganye yeyunithi bubalwa ukugqiba ubukhulu be-zinc layer. Oku kudla ngokumiselwa ngokulinganisa ubunzima bombhobho emva kokukhetha.

Iimfuno zoMgangatho: Umzekelo, i-GB / T 13912, i-ASTM A123 kunye neminye imigangatho ineemfuno ezicacileyo zobunzima be-zinc layer, kunye neemfuno zobunzima be-zinc kwimibhobho yensimbi yezicelo ezahlukeneyo zingahluka.

3. Ukufana komgangatho wegalvanized
Umaleko ophakamileyo owenziwe ngamagalvanized ufana nokuthungwa, akukho kuvuza kwaye akukho monakalo we-post plating.

Akukho kuvuza okubomvu kufunyenwe emva kovavanyo ngesisombululo se-copper sulfate, ebonisa ukuba akukho kuvuza okanye umonakalo wasemva kokufakwa.

Lo ngumgangatho ophezulu wokufakwa kwegalvanized ukuqinisekisa ukusebenza kakuhle kunye nenkangeleko.

4. Ukubambelela okuqinileyo komgca we-galvanized
Ukunamathela komgca we-galvanized luphawu olubalulekileyo lomgangatho wombhobho wensimbi, obonisa iqondo lokuqina kokudibanisa phakathi komgca we-galvanized kunye nombhobho wensimbi.

Umbhobho wensimbi uya kwenza uluhlu oluxubekileyo lwe-zinc kunye nentsimbi kunye nesisombululo se-galvanizing emva kokusabela kwibhafu yokuntywila, kwaye ukunamathela kwe-zinc layer kunokwandiswa yinkqubo yenzululwazi kunye nechanekileyo ye-galvanizing.

Ukuba i-zinc layer ayiphumi lula xa icofa nge-mallet yerubha, ibonisa ukubambelela kakuhle.
