Ishubhu elingenamthungo le-hot-dip galvanized elenza insimbi encibilikisiwe isabelane ne-iron matrix ukuze ikhiqize ungqimba lwengxubevange, ukuze i-matrix kanye nokunamathela kuhlanganiswe. I-hot-dip galvanizing iwukugcoba ipayipi lensimbi kuqala. Ukuze kukhishwe i-iron oxide ebusweni bepayipi lensimbi, ngemva kokukhetha, ihlanzwa ethangini le-ammonium chloride noma i-zinc chloride isixazululo samanzi noma isixazululo esinamanzi esixutshwe se-ammonium chloride ne-zinc chloride, bese sithunyelwa okugeza okushisayo kwediphu. I-hot-dip galvanizing inezinzuzo zokunamathela okufanayo, ukunamathela okuqinile nokuphila isikhathi eside.

1. Ukumelana nokucindezela okuphezulu: ithubhu elingenamthungo elishisayo-dip lingamelana nengcindezi ephakeme.
2. Impilo yesevisi emaphakathi ende: opende abanesilinganiso sokunamathela esingu-500g/m2 bangagcinwa iminyaka engaphezu kwengu-50 ngaphandle kokunakekelwa ezindaweni ezomile nezingaphansi kwedolobha.

3. Akukho ukunakekelwa okudingekayo ngesikhathi sokusetshenziswa: Amashubhu angenamthungo ashisayo-dip anokumelana nesimo sezulu esihle kakhulu nempilo ende yesevisi, futhi awadingi izindleko zokuwalungisa. Uma kuqhathaniswa nokudweba, kudinga ukulungiswa njalo, okugcina imali eningi kanye nezindleko zomphakathi.
4. Ukuqina okuhle, kungamelana nokulimala komshini ekuphathweni nasekuphakanyisweni: Isendlalelo samagalati siyisakhiwo se-alloy esinokuqina okuhle kakhulu kanye nezakhiwo zemishini.

5. Ukulimala kwendawo noma ukukhubazeka okuncane kusavikela: Njengoba i-zinc isebenza kakhulu ngamakhemikhali kune-iron, ngisho nokukhubazeka okuncane kungavikela insimbi eveziwe, eyisivikelo se-anode yomhlatshelo.

6. Ukuvikelwa okuphelele, akukho engeli efile: izici zokusebenza zeshubhu elingenamthungo elishisayo-dip kufanele licwilise ngokugcwele ucezu lokusebenza ku-zinc ewuketshezi, ukuze wonke amakhona ocezu lokusebenza axhumane, ikakhulukazi i-engeli ebukhali kanye ne-concave surface. ingajiya i-coating, okuyiyona futhi indawo engenakufinyelelwa ngokufutha.

7. Akuthinti izakhiwo zemishini zomklamo wokuqala: i-hot-dip galvanizing ayinawo umthelela kuzakhiwo zemishini zeshubhu engenamthungo (SMLS).

Umehluko phakathi kokushisayogalvanizingkanye nama-galvanizing abandayo:

Ishubhu elingenamthungo le-hot-dip galvanized: ukusabela okuyinkimbinkimbi ngokomzimba namakhemikhali kwenzeka phakathi kwe-matrix yepayipi lensimbi nesixazululo sokucwenga esincibilikisiwe ukuze kwakhe ungqimba lwengxube ye-zinc-iron engagqwali enesakhiwo esiqinile. I-alloy layer ihlanganiswe nesendlalelo se-zinc ehlanzekile kanye ne-substrate ye-steel tube. Ngakho-ke, inokumelana nokugqwala okuqinile.

Ishubhu elibandayo eliqinile elingenamthungo: Ungqimba lwezinki luwungqimba lwe-electroplating, futhi ungqimba lwezinc lugqitshwe ngokuzimela ne-substrate yepayipi lensimbi. Isendlalelo se-zinc sincane, futhi ungqimba lwe-zinc lumane lunamathele ku-substrate yepayipi yensimbi futhi kulula ukuwa. Ngakho-ke, ukumelana nokugqwala kwayo kubi. Ezindlini ezisanda kwakhiwa, akuvunyelwe ukusebenzisa amapayipi ensimbi abandayo njengamapayipi okuhambisa amanzi.
