Pakuyika ndikuyika nsanja yopangira zitsulo zopangira malata, nthawi zambiri zimakumana kuti mapaipi kapena zida ziyenera kudutsachitsulo kabatinsanja molunjika. Pofuna kuti zipangizo zamapaipi zidutse bwino papulatifomu, nthawi zambiri zimakhala zofunikira kudziwa malo ndi kukula kwa malo otseguka panthawi ya mapangidwe, ndipo wopanga zitsulo zopangira zitsulo adzachita kupanga mwamakonda. The ndondomeko kupanga makonda choyamba amafuna kulankhulana kwambiri ndi kusinthana zambiri pakati zitsulo grating dipatimenti kapangidwe ndi zitsulo kapangidwe dipatimenti, WOPEREKA zida ndi kafukufuku ndi mapu dipatimenti. Chifukwa cha zinthu zambiri zokhudzana ndi zomwe zikukhudzidwa, pali kusatsimikizika kwina mu kukula ndi malo a zipangizo zamakono. Pakuyika, nthawi zambiri zimakhala kuti mabowo osungidwa omwe amasungidwa sangathe kukwaniritsa zosowa za malowo. Poganizira zimenezi, pofuna kuonetsetsa mlingo zokolola za gratings zitsulo ndi kusintha kamangidwe ndi kupanga dzuwa la gratings zitsulo, mu kamangidwe kamakono ndi kupanga ndondomeko, ambiri kulankhula, ena mabowo ndi diameters ang'onoang'ono kuti n'zovuta kudziwa si makonda ndi kukonzedwa, koma m'malo ndi yachiwiri processing ndondomeko monga pa malo kutsegula, kudula, kuwotcherera, ndi kupera malinga ndi mmene unsembe ndi mmene zinthu zilili panopa pomanga zitsulo.
Monga zinthu zatsopano, zitsulo zopangira malata zimagwiritsidwa ntchito kwambiri. Galvanizing wakhala njira yofunika odana ndi dzimbiri zitsulo gratings, osati chifukwa nthaka akhoza kupanga wandiweyani zoteteza wosanjikiza pamwamba zitsulo, komanso chifukwa nthaka ali ndi cathodic chitetezo zotsatira. Pamene kanasonkhezereka zitsulo kabati amatumizidwa ku malo, yachiwiri processing ndi kuwotcherera nthawi zina chofunika unsembe. Kukhalapo kwa nthaka wosanjikiza kumabweretsa zovuta zina pakuwotcherera kwa chitsulo chamalata.
Kusanthula kwa weldability wa kanasonkhezereka zitsulo gratings
Zopangira zitsulo zopangidwa ndi zitsulo zimakutidwa ndi chitsulo chosanjikiza chachitsulo pamwamba pa chitsulo chotchinga kuti chiteteze dzimbiri pamwamba pa kabati yachitsulo ndikuwonjezera moyo wake wautumiki. Pamwamba pa chitsulo chosungunuka pamakhala ngati maluwa. Malinga ndi kupanga ndi kukonza njira, zikhoza kugawidwa m'magulu awa: ① otentha-kuviika kanasonkhezereka pepala; ② pepala lachitsulo lopangidwa ndi electrogalvanized. Malo osungunuka a zinc ndi 419 ℃ ndipo malo otentha ndi 907 ℃, omwe ndi otsika kwambiri kuposa chitsulo chosungunuka, 1500 ℃. Choncho, pa kuwotcherera ndondomeko, kanasonkhezereka wosanjikiza choyamba amasungunula makolo chuma. Pambuyo kusanthula pamwamba, mawotchi ndi thupi katundu pepala kanasonkhezereka ndi ofanana ndi wamba mpweya zitsulo pepala. Chosiyana chokha ndikuti pali zokutira zinki pamwamba pa chitsulo chosungunuka. The kuwotcherera ndondomeko kanasonkhezereka zitsulo kabati
(1) kuwotcherera pamanja
Pofuna kuchepetsa kuwotcherera utsi ndi kupewa m'badwo wa kuwotcherera ming'alu ndi pores, nthaka wosanjikiza pafupi poyambira ayenera kuchotsedwa pamaso kuwotcherera. Njira yochotsera ingakhale yophika moto kapena sandblasting. Mfundo yosankha ndodo zowotcherera ndi yakuti mawonekedwe a zitsulo zowotcherera ayenera kukhala pafupi kwambiri ndi zinthu za makolo, ndipo zomwe zili pa silicon mu ndodo yowotcherera tsiku ndi tsiku zitsulo zosungunuka ziyenera kuyendetsedwa pansi pa 0,2%. Pa galasi lachitsulo chochepa cha carbon steel grating zinki zitsulo, J421/422 kapena J423 ndodo zowotcherera ziyenera kugwiritsidwa ntchito poyamba. Mukawotcherera, yesetsani kugwiritsa ntchito arc yaifupi ndipo musagwedeze arc kuti muteteze kufalikira kwa gawo losungunuka lagalasi, onetsetsani kukana kwa dzimbiri kwa workpiece ndikuchepetsa kuchuluka kwa utsi.
(2) Kuwotcherera zitsulo
Gwiritsani ntchito kuwotcherera kotetezedwa ndi mpweya wa CO2 kapena kuwotcherera kotetezedwa ndi gasi monga Ar+CO2, Ar+02 powotcherera. Kuteteza mpweya kumakhudza kwambiri Zn zomwe zili mu weld. Pamene CO2 yoyera kapena CO2 + 02 ikugwiritsidwa ntchito, Zn zomwe zili mu weld zimakhala zapamwamba, pamene Ar + CO2 kapena Ar + 02 imagwiritsidwa ntchito, Zn zomwe zili mu weld zimakhala zochepa. Zomwe zilipo zilibe mphamvu zochepa pazomwe zili mu Zn mu weld. Pomwe kuwotcherera kukuchulukirachulukira, zomwe zili mu Zn mu weld zimachepa pang'ono. Mukamagwiritsa ntchito kuwotcherera kotetezedwa ndi gasi kuti muwotchere zitsulo zokometsera, kutentha kwapang'onopang'ono kumakhala kokulirapo kuposa kuwotcherera kwa arc, chifukwa chake kuyenera kuperekedwa chisamaliro chapadera pakutha. Zinthu zomwe zimakhudza kuchuluka kwake komanso kapangidwe ka utsi ndizomwe zimakhalapo komanso mpweya woteteza. Zokulirapo zapano, kapena zazikulu za CO2 kapena O2 zomwe zili mu gasi woteteza, utsi wowotcherera, komanso zomwe zili mufuko la ZnO zimawonjezekanso. Zomwe zili mu ZnO zimatha kufika pafupifupi 70%. Pansi pa zowotcherera zomwezo, kuya kwa kulowera kwa zitsulo zopangira malata ndikokulirapo kuposa kabati kopanda chitsulo.
