Pa unsembe ndi anagona nsanja structural wa kanasonkhezereka zitsulo kabati, nthawi zambiri anakumana kuti mapaipi kapena zipangizo ayenera kudutsa zitsulo grating nsanja ofukula. 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. Njira yopangira makonda imafunikira dipatimenti yopangira zitsulo kuti ilankhule ndikusinthana zambiri ndi dipatimenti yopangira zitsulo, wopereka zida, ndi dipatimenti yowunikira ndi kupanga mapu. Chifukwa cha zinthu zambiri zokhudzana nazo, komanso kukula ndi malo a zidazo zimakhala ndi zosadziwika bwino. Pakuyika ndi kumanga, nthawi zambiri zimakhala kuti mabowo osungidwa makonda sangathe kukwaniritsa zosowa za malowo. Poganizira izi, pofuna kutsimikizira kuchuluka kwa zokolola zazitsulo zachitsulo ndikuwongolera mapangidwe ndi kupanga bwino kwa kabati yachitsulo. Pamapangidwe apano ndi kupanga, mabowo ang'onoang'ono ang'onoang'ono omwe malo awo ndi ovuta kudziwa nthawi zambiri samasinthidwa makonda ndikukonzedwa. M'malo mwake, njira zachiwiri zogwirira ntchito monga kutsegula, kudula, kuwotcherera, ndi kugaya pa malowa kumachitika malinga ndi momwe zilili panopa panthawi yokonza ndi kumanga zitsulo zachitsulo.
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, processing yachiwiri ndi kuwotcherera nthawi zina chofunika chifukwa cha kufunika unsembe. Kukhalapo kwa nthaka wosanjikiza kumabweretsa zovuta zina pakuwotcherera kwa chitsulo chamalata.
Kusanthula kwa weldability wa kanasonkhezereka zitsulo kabati
Galasi zitsulo kabati ndi kuteteza pamwamba pa kabati zitsulo ku dzimbiri ndi kuwonjezera moyo wake utumiki. Chingwe chachitsulo chachitsulo chimakutidwa pamwamba pa chitsulo chopangira chitsulo, ndipo pamwamba pa chitsulo chosungunuka chidzakhala ngati maluwa. Malinga ndi kupanga ndi kukonza njira, zikhoza kugawidwa m'magulu awa: ① otentha-kuviika kanasonkhezereka pepala; ② chitsulo chopangidwa 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 amasungunuka pamaso pa makolo chuma. Pambuyo kusanthula pamwamba, katundu mawotchi ndi thupi katundu pepala kanasonkhezereka ndi ofanana ndi wamba mpweya zitsulo pepala. Chosiyana chokha ndi chakuti pali galvanized wosanjikiza pamwamba pa kanasonkhezereka zitsulo grating. Kuwotcherera ndondomeko ya kanasonkhezereka zitsulo grating
(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 mu silicon muzitsulo zowotcherera zamoto ziyenera kulamulidwa pansi pa 0.2%. Pazitsulo zotsika za carbon galvanized steel grating, J421 / J422 kapena J423 ndodo zowotcherera ziyenera kugwiritsidwa ntchito poyamba. Mukawotchera, yesani kugwiritsa ntchito arc yaifupi ndipo musalole kugwedezeka kwa arc kuti mupewe kufalikira kwa malo osungunuka a zokutira za zinki, onetsetsani kukana kwa dzimbiri kwa ntchito ndikuchepetsa utsi.
(2) Metallurgical electrode mpweya wotetezedwa kuwotcherera kumagwiritsa ntchito kuwotcherera kwa mpweya wa CO2 kapena kuwotcherera kwa gasi wosakanikirana 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 zokhala ndi malata, utsi wowotcherera ndi wokulirapo kuposa kuwotcherera kwa arc, kotero chidwi chapadera chiyenera kuperekedwa pakutha. Zinthu zomwe zimakhudza kuchuluka kwake komanso kapangidwe ka fumezi ndizomwe zimakhalapo komanso zoteteza mpweya. Zokulirapo zamakono, kapena zazikulu zomwe zili mu C02 kapena 02 mu gasi wotchinga, utsi wowotcherera wokulirapo, komanso zomwe zili mufuko za Zn0 zimawonjezekanso. Zomwe zili mu Zn0 zimatha kufika pafupifupi 70%. Pansi pa zowotcherera zomwezo, kuya kwa chitsulo chosungunuka kumakhala kwakukulu kuposa kabati kopanda chitsulo.
