Galvanizing ndi njira yogwiritsira ntchito chitsulo chosanjikiza cha zinki ku chitsulo kapena chitsulo kuti chiteteze dzimbiri. Njirayi imagwiritsidwa ntchito popanga mapaipi, makamaka omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana monga zomangamanga, mafuta ndi gasi, komanso madzi.galvanizing miyezo ya mapaipindi zofunika kuonetsetsa ubwino ndi kukhalitsa kwa malata mapaipi. Tiyeni tidziŵe tsatanetsatane wa miyeso ya galvanizing ya chitoliro ndi zomwe akutanthauza mu mzere wokometsera chitoliro.
Chitoliro galvanizingMiyezo imakhazikitsidwa makamaka ndi bungwe lapadziko lonse la American Society for Testing and Materials (ASTM). ASTM imayika miyeso yeniyeni ya njira yopangira malata, yomwe imaphatikizapo makulidwe a galvanized layer, kumata kwa zokutira, ndi mtundu wonse wamalatapamwamba. Miyezo iyi ndi yofunika kwambiri kuti pakhale kukhulupirika kwa chitoliro cha malata ndikuwonetsetsa kuti ikugwira ntchito zosiyanasiyana.
Imodzi mwa mfundo zazikulu za chitoliro cha malata ndi ASTM A123/A123M, yomwe imatchula zofunikira zopangira malata pazinthu zachitsulo, kuphatikizapo mapaipi. Muyezo uwu umafotokoza makulidwe ochepera a zokutira, zomatira ndi kumaliza kwa chitoliro cha malata. Limaperekanso malangizo oyendera ndi kuyesa kwazokutira zamabatikuonetsetsa kutsatiridwa ndi miyezo.
In zitoliro galvanizing mizere, kutsata miyezo ya ASTM A123/A123M ndikofunikira kwambiri popanga chitoliro chamalata apamwamba kwambiri. Njira yothira malata imakhala ndi magawo angapo, kuphatikiza chithandizo chapamwamba, kuthirira madzi otentha ndi kukonza pambuyo pokonza. Gawo lirilonse liyenera kutsatira miyezo ya ASTM kuti mukwaniritse makulidwe ofunikira ndi mtundu.
Kukonzekera pamwamba kumaphatikizapo kuyeretsa mapaipi kuchotsa dzimbiri, sikelo kapena zonyansa zina zomwe zingalepheretsegalvanizingwosanjikiza kuchokera kumamatira. Gawo ili ndi lofunika kwambiri kuti mutsimikizire kumamatira koyenera kwazokutira zamabatiku chitoliro pamwamba. Njira yothira mafuta otenthetsera kumaphatikizapo kumiza mipope yoyeretsedwa mu bafa la zinki wosungunuka, zomwe zimamangirira zitsulo kuchitsulo kupanga zokutira zoteteza..
Pambuyo pa galvanizing ndondomeko, chitoliro adzadutsa pambuyo processing, zomwe zingaphatikizepo kuzimitsa, passivation kapena kuyang'ana ❖ kuyanika makulidwe ndi adhesion. Njira zopangira izi ndizofunikira kuti zitsimikizire kuti chitoliro cha malata chikukwaniritsa zofunikira za ASTM ndipo ndi okonzeka kugwiritsidwa ntchito m'njira zosiyanasiyana.
Kutsatirachitoliro galvanizingMiyezo sikuti imangotsimikizira kuti chitolirocho chili chabwino komanso chokhazikika, komanso chimathandizira kuti chitolirocho chizigwira ntchito nthawi yayitali komanso kukana dzimbiri. Chitoliro cha malata chogwirizana ndi ASTM ndi choyenera panja, chinyezi chambiri komanso malo owononga, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito monga kugawa madzi, thandizo la zomangamanga ndi mapaipi a mafakitale.
Mwachidule, miyezo yopangira chitoliro yofotokozedwa ndi ASTM International imakhala ndi gawo lofunikira pakupangira zida zopangira malata. Kutsatira muyezo uwu kumatsimikizira kutichitoliro cha malataamakwaniritsa zofunika ❖ kuyanika makulidwe, adhesion ndi khalidwe lonse. Potsatira miyezo ya ASTM,opangaakhoza kupangaapamwamba kanasonkhezereka chitolirozomwe zimapereka chitetezo chapamwamba cha dzimbiri ndi moyo wautumiki muzinthu zosiyanasiyana zamafakitale ndi zamalonda.
