Ipayipi elishisayo elishisayo

Insimbi encibilikisiwe ihlangana ne-matrix yensimbi ukukhiqiza ungqimba lwe-alloy, ukuze i-matrix kanye nokuhlanganiswa kuhlanganiswe. I-hot dip galvaning ukuqala ukucosha ipayipi lensimbi, ukuze ususe i-iron oxide ebusweni bepayipi lensimbi, ngemuva kokukhanyisa, nge-ammonium chloride noma ithangi le-ammonium chloride kanye ne-zinc chloride yethangi elihlanganisiwe lokuhlanza, bese kuthi ungene ethangi elishisayo le-dip twis. I-hot dip galvanizing inezinzuzo zokuhlanganiswa okufanayo, ukunamathela okunamandla nempilo yenkonzo ende. Iningi lezinqubo eziseNyakatho zamukele inqubo ye-Zinc Replish ye-Galvanized Belt Direct Coil Pipe.

Ipayipi elibandayo elibandayo

I-Cold Gallanized i-Electric galvanized, i-galvanized mali incane kakhulu, yi-10-50g / m2 kuphela, ukumelana kwayo kokugqwala kuhluke kakhulu kunepayipi elishisayo elishisayo. Abakhiqizi bepayipi evamile be-galvanized, ukuze baqinisekise ikhwalithi, iningi alisebenzisi i-geraning kagesi (amaplanethi abandayo). Lawo mabhizinisi amancane kuphela anemishini engapheli esetshenziswa ngogesi we-Galvanizing, iqiniso, amanani abo ashibhile. Esikhathini esizayo, amapayipi abandayo aqhekekile awavunyelwe ukusetshenziswa njengamapayipi amanzi namagesi.

Ukusabela okuyinkimbinkimbi ngokomzimba nakokhemikhali kwenzeka phakathi kwensimbi yeshubhu substrate kanye nokugeza okuncibilikisiwe ukwakha ungqimba oluqinile lwe-zinc-iron alloy ngokumelana nokugqwala. Isendlalelo se-Alloy sihlanganiswe ne-pure Zinc urder kanye ne-matrix yensimbi yensimbi. Ngakho-ke, ukumelana kwalo ukugqwala kunamandla.

Ngemuva kokuthuthukiswa kwepayipi lensimbi eshisayo ngeminyaka yo-1960 kuya ku-1970, ikhwalithi yomkhiqizo iye yathuthukiswa kakhulu, ngo-1981 kuya ku-1989 yanikezwa uMnyango Wezensimbi Wezinye izinga lezwe, ukukhiqizwa nakho kukhuphuke kakhulu Kunamathani angama-400,000, okukhishwayo ka-1999 kwamathani angaphezu kuka-600,000, futhi athunyelwa eSoutheast Asia, Africa, e-United States, eJapan, amazwe aseJapan naseJalimane kanye nezifunda. Amapayipi e-hot-dip galvanised asetshenziswa kakhulu njengamapayipi amanzi namapayipi egesi, futhi imininingwane ejwayelekile yi- + 12.5 ~ + 102 mm. Ngemuva kweminyaka yama-1990s, ngenxa yokungavikeleka koMbuso ekuvikelweni kwemvelo, ukuphathwa kwamabhizinisi okungcola okuphezulu kuya ngokuya kuqinile, "imfucumfucu emithathu" ekhiqizwa kumapayipi e-hot-galvanized kunzima ukuwaxazulula, ahlanganiswe ne Ukuthuthukiswa okusheshayo kwamapayipi wensimbi engagqwali, amapayipi e-PVC namapayipi ahlanganisiwe, kanye nombuso ukukhuthaza ukusetshenziswa kwezinto zokwakha amakhemikhali, ukusetshenziswa kwe Amapayipi ensimbi we-Galvanized avinjelwe, okwenza ukuthuthukiswa kwamapayipi ashise ama-welvanized ashibhile athinteke kakhulu ugongolo futhi abeke umkhawulo, ipayipi elishisayo elishisayo kamuva lakhiwa kancane.

Ipayipi lensimbi elibandayo elibandayo

I-Zinc under ingukuhlanganiswa kukagesi, futhi isendlalelo seZinc sibekwa ngokuzimela ngensimbi matrix yensimbi. Isendlalelo se-zinc mncane, futhi isendlalelo se-zinc sinamathele kuma-matrix ensimbi futhi kulula ukuwa. Ngakho-ke, ukumelana kwalo ukugqwala kumpofu. Ezakhiweni ezintsha zokuhlala, kuvinjelwe ukusebenzisa amapayipi ensimbi ebandayo njengamapayipi okuhlinzeka ngamanzi.
