Kukonzekera ndi Kuyeretsa Pamwamba
Mumayamba ndi kutsuka mapaipi achitsulo. Gawoli limachotsa dothi, mafuta, ndi zina zodetsa. Ngati simukutsuka, zinc coating sidzagwira bwino. Muyenera kuchotsa weld slag, burrs, mill scale, varnishes, epoxies, mchenga, utoto wochokera ku mafuta, ma crayon marks, ndi sera yokhuthala kapena mafuta. Mumagwiritsa ntchito bafa yochotsa mafuta ndi sodium hydroxide kuti muchotse mafuta ndi mafuta. Mukachotsa mafuta, mutsuka mapaipi ndi madzi. Kenako mumagwiritsa ntchito hydrochloric kapena sulfuric acid kuti muchotse dzimbiri ndi mill scale. Gawoli limatchedwa pickling.
Langizo: Nthawi zonse tsukani mapaipi mukamaliza kutsuka ndi asidi kuti muchotse zotsalira zonse za asidi. Umitsani mapaipiwo musanapite ku gawo lotsatira.
Kusakaniza Mapaipi a Chitsulo
Kenako, mumaviika mapaipi mu njira yothira madzi. Kuthira madzi kumachotsa ma oxide otsala ndikuletsa kukhuthala kwatsopano musanaphike mapaipi ndi zinc. Mumagwiritsa ntchito njira yothira madzi ya zinc ammonium chloride pa sitepe iyi. Kutentha kwabwino kwambiri kothira madzi ndi pakati pa 60 ndi 80 °C. Kutentha kumeneku kumathandiza kuti madzi ayeretse bwino pamwamba pa chitsulo. Zinthu zazikulu zothira madzi ndi zinc chloride ndi ammonium chloride. Mankhwalawa amachotsa iron oxide ndikuwonjezera kuyenda kwa zinc. Kuthira madzi kumakuthandizaninso kugwiritsa ntchito zinc yochepa ndikuchepetsa zinyalala.
- Zinki kolorayidi: 60–80%
- Ammonium chloride: 7–20%
- Zinthu zosinthira madzimadzi: 2–20%
- Mankhwala ena: nickel, cobalt, manganese, lead, tin, bismuth, antimony
Kumizidwa mu Zinc Bath
Kenako mumaviika mapaipiwo mu bafa ya zinc yosungunuka. Zipangizo zotenthetsera zinki zomwe zimagwiritsidwa ntchito pa chitoliro chachitsulo zimasunga bafa ya zinc pa kutentha koyenera, nthawi zambiri pakati pa 825 ndi 870 °F (440–460 °C). Mumasunga mapaipiwo mu bafa kwa mphindi 5 mpaka 15. Nthawi ino zinki imagwirizana ndi chitsulo ndikupanga chophimba cholimba komanso chofanana. Bafa ya zinc imaphimba gawo lililonse la chitolirocho, ngakhale mkati ndi mozungulira ma weld.
Dziwani: Ngati simukulamulira kutentha kapena nthawi, mutha kukhala ndi zolakwika monga ziphuphu, matuza, kapena kutsekeka.
Kuziziritsa ndi Kuyeretsa Komaliza
Mukachotsa mapaipi mu bafa la zinc, mumawaziziritsa mu thanki yozimitsira moto. Kuziziritsa kumaletsa kuyanjana pakati pa zinc ndi mpweya. Kenako mumatsuka mapaipi ndi madzi abwino kuti muchotse mankhwala otsala. Ngati munagwiritsa ntchito kuyeretsa ndi asidi, tsukani mapaipi kachiwiri. Umitsani mapaipi ndi mpweya wotentha kuti muwonetsetse kuti palibe chinyezi chomwe chikutsalira. Gawoli limasunga pamwamba pa madzi kukhala paukhondo komanso kupewa dzimbiri loyera.
- Tsukani ndi madzi abwino
- Umitsani ndi mpweya wotentha
- Sungani mapaipi pamalo ouma
Kuyesa ndi Kuyesa Ubwino
Muyenera kuyang'ana mapaipi kuti muwonetsetse kuti chophimbacho ndi cholimba komanso chofanana. Mumagwiritsa ntchito ma check owoneka bwino, miyeso yokhuthala, ndi mayeso ofanana. Mumayang'ananso ngati pali kuuma, dzimbiri, ndi kuwonongeka. Mumayesa kukula kwa chitolirocho ndikuyang'ana ngati pali kutayikira. Mumatsatira miyezo monga ASTM A500 ndi EN 10219. Miyezo iyi imakuthandizani kuonetsetsa kuti mapaipiwo apitilizabe kugwira ntchito komanso kuti asachite dzimbiri.
Njira Yowunikira Kufotokozera Kuyang'ana kowoneka bwino Yang'anani ngati pali kusalala, zolakwika, ndi dzimbiri Kukhuthala kwa gawo Gwiritsani ntchito mita kuti muyese makulidwe a chophimba Kufanana Yang'anani ngati pali kupotoka kapena kupotoka kosagwirizana Kuuma Kuyesa kuuma kwa pamwamba Kuyang'anira dzimbiri Pezani mikwingwirima kapena kuwonongeka Ubwino wa kuwotcherera Yang'anani ngati pali ming'alu kapena matope Kapangidwe ka mankhwala Yesani kuchuluka kwa zinc ndi chitsulo komwe kuli koyenera Khalidwe la makina Yesani mphamvu ndi kusinthasintha Kuyang'anira miyeso Tsimikizani m'mimba mwake, makulidwe, ndi kutalika Logo ndi kulemba Yang'anani zilembo zolondola Mayeso otayikira Onetsetsani kuti mapaipi alibe ming'alu kapena mabowo Chikumbutso cha Chitetezo: Nthawi zonse tsatirani malamulo a chitetezo mukamagwiritsa ntchito zida zotenthetsera mapaipi achitsulo. Yang'anani mapaipi kuti muwone ngati awonongeka ndipo onetsetsani kuti madzi ndi abwino kuti apewe dzimbiri.
Ubwino wa Chida Chopangira Ma Galvanizing cha Chitoliro cha Chitsulo
Chitetezo Chapamwamba cha Dzimbiri ndi Kudzimbidwa
Mumapeza chitetezo champhamvu ku dzimbiri mukamagwiritsa ntchitozida zotenthetsera zitsulo zotenthetsera chitoliro chachitsuloChophimba cha zinc chimapanga chotchinga cholimba chomwe chimateteza madzi, mpweya, ndi mankhwala kutali ndi chitsulo. Chotchinga ichi chimagwira ntchito bwino kuposa utoto kapena zophimba zopyapyala. Zinc imatetezanso chitsulocho ngati chophimbacho chakanda. Zinc idzayamba kuwononga, zomwe zimapulumutsa chitsulo chomwe chili pansi pake.
- Zinc yokhuthala imapirira nyengo yoipa komanso mankhwala.
- Mukuwona njira iyi ikugwiritsidwa ntchito pa milatho, zipilala, ndi mapaipi akunja chifukwa imatenga nthawi yayitali.
- Chophimba cha zinki chimagwiritsa ntchito zotchinga komanso zoteteza, kotero mapaipi anu amakhala otetezeka ngakhale pamwamba pake pawonongeka.
Kafukufuku wa sayansi akusonyeza kuti zinc imapanga mankhwala apadera, monga ZnO ndi Zn5Cl2(OH)8, omwe amachepetsa dzimbiri ndikusunga mapaipi olimba m'malo ovuta.
Njira Kufotokozera Chitetezo cha Zotchinga Zinc layer imatseka madzi ndi mpweya kuti zisafike kuchitsulo. Chitetezo cha Nsembe Zinc imawononga chitsulo chisanayambe kugwiritsidwa ntchito, ndipo imachiteteza ngakhale chitakanda. Nyengo Yachilengedwe Pakapita nthawi, zinc imapanga zigawo zina zomwe zimawonjezera chitetezo. Kukhalitsa Kwambiri ndi Kukhala ndi Moyo Wautali
Mungayembekezere kuti mapaipi opangidwa ndi galvanized azikhala kwa zaka zambiri. Pamene utoto wa zinc uli wokhuthala, mapaipi anu adzakhalapo kwa nthawi yayitali. Mwachitsanzo:
Mtundu Wokutira Nthawi Yomwe Amayembekezera Kukhala M'malo Ocheperako G30 Zaka 5–10 G90 Zaka 20 kapena kuposerapo Mapaipi ambiri okhala ndi magalasi amakhala zaka 40 mpaka 50. M'malo ouma, amatha kukhala nthawi yayitali. Ngati mugwiritsa ntchito zida zotenthetsera magalasi zotenthetsera paipi yachitsulo, mumathandiza mapaipi anu kuti asawonongeke ndi dzimbiri kwa zaka zambiri.
- Mapaipi omwe ali m'malo opanda chinyezi chochepa amatha kukhala zaka 70.
- M'malo onyowa kapena amchere, nthawi ya moyo wa chinthucho ingakhale yochepa, koma yayitali kwambiri kuposa chitsulo chosaphimbidwa.
Kugwiritsa Ntchito Ndalama Moyenera Komanso Kusamalira Kochepa
Mumasunga ndalama pakapita nthawi pogwiritsa ntchito mapaipi a galvanized. Mtengo woyamba ndi wokwera pang'ono kuposa utoto, koma mumawononga ndalama zochepa pakukonza ndi kukonza. Nayi fanizo lalifupi:
Njira Yotetezera Mtengo Woyamba Chiyembekezo cha Moyo (zaka) Ndalama Zokonzera NPV Kuviika mu Dip Yotentha 100 25 0 100 Dongosolo la Utoto 90 8 169 169 Mapaipi okhala ndi galvanized amafunika kutsukidwa pang'ono komanso kukonzedwa kochepa. Kuphimba kwawo kolimba kumatanthauza kuti simuyenera kuda nkhawa ndi dzimbiri kapena kutuluka madzi nthawi zambiri. Izi zimapangitsa kuti akhale chisankho chanzeru pamapulojekiti akuluakulu komanso malo omwe mukufuna kuti mapaipi akhale nthawi yayitali.
Zipangizo zotenthetsera ma galvanizing zimakuthandizani kuteteza mapaipi achitsulo kwa zaka zambiri. Mumapeza magwiridwe antchito odalirika m'malo osiyanasiyana.
- Kukhalitsa kwa nthawi yayitali kumadalira momwe zinthu zilili.
- Akatswiri amatiGawo lililonse la ndondomeko limakhudzaubwino ndi mphamvu ya chophimba.
Gawo Zotsatira pa Kugwira Ntchito Bwino Kuyeretsa Zimathandiza kuti munthu azigwirizana bwino komanso kupewa zolakwika Kusankha Zimakhudza kusalala ndi khalidwe Kusuntha Zimatsimikizira kuti zinc imayenda mofanana Kumiza Amalamulira makulidwe ndi khalidwe lamkati Kuyendera Kutsimikizira kuti chophimbacho chikukwaniritsa miyezo
