Chitoliro Chothiridwa Ndi Galvanized
Pofuna kukonza dzimbiri kukana kwa mipope zitsulo, ambiri zitsulo mapaipi ndi kanasonkhezereka.Mipope yachitsulo imagawidwa m'mitundu iwiri: galvanizing yotentha ndi electro-galvanizing.Kutentha-kuviika galvanizing wosanjikiza ndi wandiweyani, mtengo wa electro-galvanizing ndi otsika, ndipo pamwamba si yosalala kwambiri.
Chitoliro chowombedwa ndi okosijeni: Chimagwiritsidwa ntchito ngati chitoliro chopangira chitsulo chowuzira mpweya wa okosijeni, mapaipi achitsulo ang'onoang'ono, okhala ndi mawonekedwe asanu ndi atatu kuyambira mainchesi 3/8 mpaka 2.Zimapangidwa ndi chitsulo cha 08, 10, 15, 20 kapena 195-Q235, pofuna kupewa dzimbiri, ndikofunikira kuchita chithandizo cha aluminizing.
Nyumba zambiri zakale zimagwiritsa ntchito mapaipi a malata.Mapaipi achitsulo omwe amagwiritsidwa ntchito popangira gasi ndi kutenthetsa ndi mapaipi amalata.Mipope ya malata imagwiritsidwa ntchito ngati mapaipi amadzi.Pambuyo pa zaka zingapo zogwiritsidwa ntchito, dzimbiri ndi dothi zambiri zimapangidwira m'mipope, ndipo madzi achikasu omwe amatuluka samangoipitsa zinthu zaukhondo., Ndipo kusakanikirana ndi mabakiteriya omwe amaswana pakhoma lamkati lamkati, dzimbiri limayambitsa zitsulo zolemera kwambiri m'madzi, zomwe zimaika pangozi thanzi la munthu.M’zaka za m’ma 1960 ndi m’ma 1970, maiko otukuka padziko lapansi anayamba kupanga mitundu yatsopano ya mapaipi ndipo pang’onopang’ono analetsa mapaipi a malata.Unduna ndi makomiti anayi kuphatikiza unduna wa zomangamanga ku China adaperekanso chikalata chofotokoza kuti mapaipi a malata aletsedwa kuyambira 2000 kupita m'tsogolo.Mapaipi a malata sagwiritsidwa ntchito kawirikawiri popanga madzi ozizira m'madera omwe adamangidwa kumene pambuyo pa 2000, ndipo mapaipi a malata amagwiritsidwa ntchito popanga madzi otentha m'madera ena.

Mapaipi achitsulo amagawidwa m'mapaipi ozizira opaka malata ndi mipope yamalata yotentha.Zakale zaletsedwa, ndipo zotsirizirazo zalimbikitsidwa ndi boma kuti zigwiritsidwe ntchito kwakanthawi.
Hot-kuviika kanasonkhezereka chitoliro
Chitoliro chovimbika chotenthetsera ndicho kupanga chitsulo chosungunuka ndi matrix achitsulo kuchitapo kanthu kuti apange wosanjikiza wa aloyi, kuti matrix ndi zokutira ziphatikizidwe.Hot-kuviika galvanizing ndi pickle zitsulo chitoliro choyamba.Kuchotsa chitsulo okusayidi pamwamba pa chitoliro zitsulo, pambuyo pickling, izo kutsukidwa mu thanki ya ammonium kolorayidi kapena zinki kolorayidi amadzimadzi njira kapena osakaniza amadzimadzi njira ya ammonium kolorayidi ndi nthaka kolorayidi, ndiyeno kutumizidwa In. tanki yothira madzi otentha.Hot-dip galvanizing ili ndi ubwino wa zokutira yunifolomu, kumamatira mwamphamvu komanso moyo wautali wautumiki.
Chitoliro chozizira chamalata
Cold galvanizing ndi electro-galvanizing, ndipo kuchuluka kwa galvanizing ndi kochepa kwambiri, kokha 10-50g / m2, ndipo kukana kwake kwa dzimbiri ndi koipa kwambiri kuposa mipope yotentha yoviika malata.Ambiri mwa opanga zitoliro zokhala ndi malata nthawi zonse sagwiritsa ntchito magetsi opangira magetsi (kuzizira kozizira) kuti atsimikizire mtundu wake.Mabizinesi ang'onoang'ono okha omwe ali ndi zida zazing'ono komanso zakale amagwiritsa ntchito electro-galvanization, ndipo zowonadi mitengo yawo ndi yotsika mtengo.Unduna wa Zomangamanga walengeza kuti mapaipi aziziziritsa okhala ndi ukadaulo wachikale achotsedwe, ndipo mapaipi ozizira sadzaloledwa kugwiritsidwa ntchito ngati mapaipi amadzi ndi gasi mtsogolomo.
Chitoliro chachitsulo chovimbika chotentha: Chitoliro chachitsulo chachitsulo chimakhala ndi zovuta zakuthupi ndi zamankhwala ndi njira yosungunula yosungunuka kuti ipange chosanjikiza chachitsulo cha zinc-iron chosakanikirana.Chosanjikiza cha alloy chimaphatikizidwa ndi wosanjikiza wa zinc koyera ndi matrix achitsulo chitoliro.Choncho, kukana kwake kwa dzimbiri ndi kolimba.
Chitoliro chachitsulo chozizira:Zinc wosanjikiza ndi electroplated wosanjikiza, ndi nthaka wosanjikiza ndi zitsulo chitoliro gawo lapansi ndi wosanjikiza paokha.Zinc wosanjikiza ndi woonda, ndi nthaka wosanjikiza amangotsatira zitsulo chitoliro gawo lapansi ndipo n'zosavuta kugwa.Chifukwa chake, kukana kwake kwa dzimbiri ndikochepa.M'nyumba zomangidwa kumene, sikuloledwa kugwiritsa ntchito mapaipi achitsulo ozizira ngati mapaipi operekera madzi.
Kapangidwe kachitsulo chosapanga dzimbiri ali ndi njira zopangira izi:
a.Kukonzekera zitsulo zozungulira;b.Kutentha;c.Kuboola kotentha kotentha;d.Dulani mutu;e.Pickling;f.Kupera;g.Kupaka mafuta;h.Cold anagubuduza processing;ndi.Kuchepetsa mafuta;j.Solution kutentha mankhwala;k.Kuwongola;l.Dulani chubu;m.Pickling;n.Kuyesa kwazinthu.
Ingoperekani ndondomeko yonse, ndipo zowonjezereka zimakhala zachinsinsi cha wopanga aliyense
1. Brand ndi mankhwala
Magulu ndi mankhwala azitsulo zamapaipi azitsulo zokhala ndi malata ayenera kutsatizana ndi kalasi ndi mankhwala azitsulo zazitsulo zakuda zomwe zatchulidwa mu GB 3092.
2. Njira yopanga
Njira yopangira chitoliro chakuda (kuwotchera ng'anjo kapena kuwotcherera magetsi) imasankhidwa ndi wopanga.Kutentha kwa dip galvanizing kumagwiritsidwa ntchito pokometsera.
3. Ulusi ndi zitoliro olowa
3.1 Kwa mapaipi achitsulo opangidwa ndi malata operekedwa ndi ulusi, ulusiwo uyenera kupangidwa pambuyo pakukomerera.Ulusi uyenera kutsata malamulo a YB 822.
3.2 Mapaipi achitsulo ayenera kutsatira YB 238;mfundo zolumikizira mapaipi achitsulo zosungunuka ziyenera kutsatira YB 230.
4. Zida zamakina Zomwe zimapangidwira zamapaipi achitsulo musanapangire malata ziyenera kukwaniritsa zofunikira za GB 3092.
5. Kufanana kwa gawo la malata Chitoliro chachitsulo chopangidwa ndi chitsulo chiyenera kuyesedwa kuti chikhale chofanana ndi chachitsulo.Chitsanzo cha chitoliro chachitsulo sichidzasanduka chofiira (mtundu wa mkuwa) mutamizidwa mumkuwa wa sulphate kwa nthawi 5 zotsatizana.
6. Cold bend test Chitoliro chachitsulo chokhala ndi malata chokhala ndi m'mimba mwake osapitirira 50mm chiyenera kuyesedwa kozizira.Kopindika ndi 90 °, ndipo utali wopindika ndi 8 kuwirikiza kwakunja.Palibe filler panthawi yoyesera, ndipo weld ya chitsanzo iyenera kuikidwa kunja kapena kumtunda kwa njira yopindika.Pambuyo pa mayeso, sikuyenera kukhala ming'alu ndi kusenda kwa nthaka wosanjikiza pazatsanzo.
7. Mayeso a kuthamanga kwa madzi Mayeso a kuthamanga kwa madzi ayenera kuchitidwa mu clarinet.Kuzindikira zolakwika za Eddy kungagwiritsidwenso ntchito m'malo moyesa kuthamanga kwa madzi.Kuthamanga kwa mayeso kapena kukula kwa chitsanzo chofananitsa cha kuyesa kwamakono kwa eddy kudzakwaniritsa zofunikira za GB 3092.
