Kuyaziwa ukuthi izingaamashubhu ayizikwele angu-galvanized kanye nama-rectangularfuthi indlela yokufaka ithinta ngokuqondile ukuzinza kwezakhiwo zensimbi.
Njengamanje, izinto zokusekela emakethe ikakhulukazi yi-carbon steel.Izinto zokusetshenziswa ze-carbon steel ngokuvamile ziyi-Q235 kanye ne-Q345, eziphathwa ngokufaka ama-galvanizing ashisayo.Ukusekelwa kwenziwa nge-strip steel coil ngokusebenzisa ukugoba okubandayo, i-welding, i-galvanizing eshisayo nezinye izinqubo.Ngokuvamile, ukushuba kufanele kube kukhulu kuno-2mm, futhi ikakhulukazi kwezinye izindawo ezisogwini, eziphakeme kanye nezinye izindawo nezindawo ezinomoya, kunconywa ukuthi ukushuba akufanele kube ngaphansi kuka-2.5mm, ngaphandle kwalokho kunengozi yokudabula insimbi. indawo yokuxhumana.
Ezakhiweni ezinkulu zokwakha, forcarbon steel galvanized square namapayipi angama-rectangular, kungakanani ukujiya kwe-zinc okufanele kufinyelelwe ukuze kuhlangatshezwane nezidingo zempilo yesevisi yokugqwala kwemvelo?
Njengoba sonke sazi, ubukhulu be-hot-dip galvanizing iyikhwalithi ebalulekile kanye nenkomba yezobuchwephesheipayipi eliyisikwele elinothayela, okuhlobene nokuphepha nokuqina kwesakhiwo.Nakuba kunezindinganiso zikazwelonke nezomsebenzi, ukushuba kwe-zinc enamathelayo okungafanelekile kuseyinkinga ebanzi yobuchwepheshe yokusekelwa.
Inqubo ye-hot-dip galvanizing iwuhlelo oluzinzile futhi oluthembekile lwensimbi yokwelashwa olumelana nokugqwala kwemvelo.Kunezici eziningi ezithinta i-hot-dip galvanizing, njengokubunjwa kwe-substrate yensimbi, isimo sangaphandle (njengokulukhuni), ukucindezeleka kwangaphakathi kwe-substrate, nosayizi abambalwa.Phakathi nale nqubo, ubukhulu be-substrate bunomthelela omkhulu ebukhulu be-hot-dip galvanizing.Ngokuvamile, uma ipuleti lijiya, ubukhulu be-hot-dip galvanizing buba bukhulu.Ukwesekwa okunogqinsi oluwu-2.0mm kuthathwa njengesibonelo ukukhombisa ukuthi kungakanani ukujiya kwe-zinc enamathelayo okudingekayo ukuze kwanelise izidingo zempilo yesevisi yokugqwala.
Cabanga ukuthi ubukhulu besisekelo sokusekela singu-2mm, ngokuya ngezinga elijwayelekile le-GBT13192-2002 elishisa izikhotha.
Bungakanani ubukhulu bongqimba lukathayela lwepayipi eliyisikwele elidingekayo ukuze kuhlangatshezwane nezidingo zempilo yesevisi?
Umbhobho oyisikwele ophekiwe
Ngokwezidingo zezinga likazwelonke, ukujiya kwesisekelo sempahla engu-2mm akumele kube ngaphansi kuka-45 μ m.Ugqinsi olulinganayo akumele lube ngaphansi kuka-55 μ m. Ngokwemiphumela yokuhlolwa kokuchayeka emkhathini okwenziwa yi-Japanese Hot Dip Galvanizing Association kusukela ngo-1964 kuya ku-1974. Buyini ubukhulu bongqimba lukathayela lwepayipi eliyisikwele elidingekayo ukuze kuhlangatshezwane nezidingo zempilo yesevisi ?
Uma kubalwa ngokwezinga likazwelonke, okuqukethwe kwe-zinc kungu-55x7.2=396g/m2,
Impilo yesevisi etholakala ezindaweni ezine ezahlukene imayelana:
Indawo yezimboni esindayo: iminyaka engu-8.91, ene-corrosion degree yonyaka engu-40.1;
Indawo yogu: iminyaka engu-32.67, enezinga lokugqwala lonyaka lika-10.8;
Ngaphandle: iminyaka engu-66.33, ne-corrosion degree yonyaka engu-5.4;
Indawo yasemadolobheni: iminyaka engu-20.79, ne-corrosion degree yonyaka engu-17.5
Uma kubalwa ngokuvumelana nokuphila kwesevisi ye-photovoltaic yeminyaka engu-25
Bese ukulandelana kwezindawo ezine okungenani:
1002.5270135437.5, okungukuthi 139 μ m, 37.5 μ m, 18.75 μ m, 60.76 μ m.
Ngakho-ke, ngokusatshalaliswa kwezindawo zasemadolobheni, ubukhulu be-zinc coating kufanele okungenani bube ngu-65 μ M bunengqondo futhi buyadingeka, kodwa ezindaweni ezisindayo zezimboni, ikakhulukazi lezo ezine-acid kanye ne-alkali corrosion, kunconywa ukuthi ubukhulu bepayipi yesikwele se-galvanized. futhi i-zinc enamathela kufanele yengezwe kahle.
