1. Maganin Kafin a Yi Amfani da Substrate: "Gargadin Asali" na Daidaito Mai Girma
Ingancin substrate donna'urar ƙarfe ta galvalumekai tsaye yana shafar aikin ƙarshe na girma. Tsarin aikin ya haɗa da tsinken tsinkewa da daidaita shi:
* Tsarin Tsaftacewa: Idan lokacin tsaftacewa ya yi tsayi ko kuma yawan sinadarin acid ya yi yawa, zai haifar da tsatsa mai yawa a saman substrate, wanda zai iya haifar da raguwar gida da kuma karkacewa cikin sauƙi yayin sanyaya bayan an shafa shi. Akasin haka, tsaftacewa mara cikakke zai bar sikelin oxide, wanda zai haifar da rashin mannewa mai kyau kuma yana shafar daidaiton girma a kaikaice. Manyan coils na ƙarfe na galvalume galibi suna amfani da tsarin "tsaftacewa mara zurfi + gogewa ta yanar gizo", wanda ke sarrafa yawan sinadarin acid (18-22%) da lokacin magani (30-40s) don guje wa lalacewar substrate.
* Tsarin Daidaita ...
2. Tsarin Shafawa Mai Zafi: "Daidaitaccen Daidaito" na Zafin Jiki da Sauri
Rufin da aka tsoma a cikin ruwan zafi shine babban matakin samar da murfin galvalume na ƙarfe. Sigogin aikin sa suna shafar daidaiton kauri na rufi da nakasawar substrate kai tsaye: Kula da zafin tukunyar zinc: Matsakaicin zafin murfin zafi shine 600-620℃. Idan canjin zafin jiki ya wuce ±5℃, zai haifar da rashin daidaituwa na haɗin murfin, wanda ke haifar da lahani kamar "gefe masu kauri" da "substrate da aka fallasa," don haka yana shafar juriyar kauri gaba ɗaya na nada. Daidaita saurin tsiri: Gudun tafiyar tsiri dole ne ya dace da saurin mannewa na rufi (yawanci 10-15m/min). Girman gudu da yawa zai iya haifar da sirara da rashin daidaituwa cikin sauƙi, yayin da ƙarancin gudu zai haifar da rufewa mai kauri da nakasa mai zafi na substrate. Layukan samar da coils na ƙarfe na galvalume suna da tsarin auna zafin jiki na infrared da tsarin sarrafa saurin rufewa don tabbatar da daidaiton sigogi.
3. Tsarin Sanyaya: Babban Mataki wajen Hana Nakasa
Sanyaya cikin sauri bayan an tsoma galvanizing a cikin ruwan zafi yana da mahimmanci don hana lalacewar zafi na coil ɗin ƙarfe na galvalume. Idan an yi amfani da sanyaya ta halitta, bambancin da ke cikin ma'aunin faɗaɗa zafi tsakanin substrate da shafi (ƙarfe: 11.5 × 10⁻⁶/℃, aluminum-zinc alloy: 23 × 10⁻⁶/℃) zai haifar da matsananciyar damuwa ta zafi, wanda ke haifar da warping na coil da kuma yawan waveness. Masu samar da coil ɗin galvalume masu inganci suna amfani da tsarin sanyaya mai sassauƙa: da farko, sanyaya iska yana rage zafin jiki zuwa 300℃, sannan sanyaya ruwa mai atom ya rage shi zuwa zafin ɗaki, tare da sarrafa saurin sanyaya a 15-20℃/s, wanda hakan ke rage damuwar zafi yadda ya kamata. Manyan masu samar da coil ɗin galvalume a China sun ƙara gabatar da tsarin sanyaya mai wayo waɗanda ke daidaita ƙarfin sanyaya a ainihin lokaci bisa ga kauri na tsiri don tabbatar da daidaiton girma.
4. Tsarin Kammalawa: Daidaita Ma'aunin Ƙarshe
Kammalawa bayan an gama shafa kai tsaye yana ƙayyade daidaiton girma nagalvalume na coilTsarin aikin ya haɗa da matakai biyu: daidaita matsin lamba da kuma rage gefen. Daidaita matsin lamba: Ana amfani da ƙimar matsin lamba ta kashi 1-2% ta amfani da injin daidaita matsin lamba don kawar da damuwa da ke cikin na'urar da kuma gyara ɗan karkacewa, don tabbatar da cewa takardar ta kai matsayin da ya dace. Gyaran Gefen: Ana amfani da injin gyaran gefen CNC don daidaita juriyar faɗin na'urar (ɓacewa ≤ ±2mm), don guje wa matsaloli a shigarwa da haɗakarwa daga baya saboda gefuna marasa daidaito. Tsarin kammalawa na na'urorin ƙarfe na Prime galvalume suma sun haɗa da duba girman kan layi; ana mayar da samfuran da suka lalace kai tsaye don sake yin aiki.
III. Sayayya da Zaɓe: Ta Yaya Ake Yin Alƙawarin Daidaito Tsakanin Tsarin Aiki?
Ga kamfanoni da ke siyan kayayyakin galvalume don siyarwa, ana iya amfani da waɗannan maki uku don tantance samfuran masu inganci: Nemi rahotannin sigogin tsari daga masu samar da coil na galvalume, mai da hankali kan mahimman alamomi kamar daidaiton daidaita substrate, kewayon canjin zafin jiki na tukunyar zinc, da hanyar sanyaya; Ba da fifiko ga coils na ƙarfe na galvalume na Prime, saboda tsarin samarwarsu yana amfani da cikakken sarrafawa ta atomatik, yana tabbatar da mafi kyawun haƙurin girma; Kula da cancantar masu samar da kayayyaki na galvalume coil na china. Manyan masu samar da kayayyaki galibi suna da kayan aikin gwaji na daidai (kamar ma'aunin kauri na laser da kayan aikin auna siffa) kuma suna iya samar da rahotannin dubawa na ɓangare na uku.
Kwanciyar hankali na girman galvalume na ƙarfe sakamakon "sarrafa matakin milimita" ne a cikin tsarin samarwa. Daga gyaran substrate kafin zuwa kammalawa da jigilar kaya, karkacewar sigogi a kowane mataki na iya shafar ingancin ƙarshe. Ga masu samar da galvalume coil, haɓaka tsari shine mabuɗin haɓaka gasawar samfura; ga masu siye, fahimtar alaƙar da ke tsakanin tsari da kwanciyar hankali na girma yana da mahimmanci don zaɓar madaidaicin murhun ƙarfe na galvalume wanda ya dace da buƙatunsu. A nan gaba, tare da sake fasalin fasaha na masana'antar galvalume coil ta China, kwanciyar hankali na girma zai zama babban alamar da ke bambanta samfuran inganci daga samfuran yau da kullun, wanda ke haifar da aikace-aikacen galvalume na ƙarfe a cikin yanayi mafi daidaito.
