An riga an fenti Galvalume Coil, wanda kuma ake kira Ppgl Coil ko Ppgl Steel Coil, muhimmin abu ne don gina bangon labule, gidajen kayan aiki, da jigilar kayayyaki cikin sanyi. Juriyar tsatsa tana shafar rayuwar sabis na samfurin, farashin kulawa, da aminci. A cikin mawuyacin yanayi kamar yankunan ruwa da wuraren gurɓataccen masana'antu, nemo hanyoyin haɓaka juriyar tsatsa na Ppgl Steel babban abin damuwa ne a masana'antar. Wannan labarin ya ba da dabaru guda biyar masu amfani waɗanda suka dogara da amfani na gaske a duniya.
I. Inganta Tsarin Ƙasa: Farawa Mai Kyau Don Jure Tsatsa
Juriyar tsatsa ta Ppgl Steel ta dogara ne akan substrate ɗinsa, wanda aka yi da aluminum zinc-plated substrate (Galvalume Coil).
1. Kula da Rufin: Kyakkyawan Rufin Karfe na Ppgl yana buƙatar haɗin aluminum (55%), zinc (43.4%), da silicon (1.6%). Silicon yana taimakawa wajen samar da layin ƙarfe kuma yana hana barewa. Rufin zinc na aluminum ya kamata ya zama aƙalla 120 g/m² (gefen biyu). A yankunan bakin teku masu lalata sosai, yana iya kaiwa sama da 150 g/m² don samar da Layer mai ƙarfi na kariya.
2. Zaɓi Tsabtataccen Substrate: Ya kamata substrate ɗin ƙarfe na Ppgl ya kasance yana da ƙarancin gurɓataccen abu kamar carbon da sulfur. Wannan yana rage ƙananan lahani kuma yana hana tsatsa farawa. Ya fi kyau a yi amfani da substrates ɗin zinc da aka lulluɓe da aluminum waɗanda suka cika ƙa'idodin ASTM A792 don rage haɗarin tsatsa.
II. Yi wa saman kyau da kyau: Inganta mannewa a saman
Mannewar ƙarfen Galvalume da aka riga aka fenti yana shafar juriyarsa ga tsatsa. Gyaran saman yana da matuƙar muhimmanci:
1. Tsaftace a Matakai Uku: Ya kamata a yi amfani da sinadarin alkaline don cire mai, a yi amfani da sinadarin acid don cire tsatsa, sannan a yi kurkure don rage tsatsa. Wannan yana tabbatar da cewa saman ya yi tsafta kuma yana dakatar da "tsatsa tsakanin rufin da kuma saman.
2. Haɓaka Passivation: Yi amfani da chromate passivation ko chromium - free passivation (wanda ya fi kyau ga muhalli). Wannan yana samar da fim ɗin passivation iri ɗaya akan murfin Galvalume Steel Coil substrate. Yana taimaka wa murfin ya manne da kyau kuma ya toshe abubuwan da ke lalata.
3. Busar da shi yadda ya kamata: Bayan an riga an yi masa magani, a busar da shi da sauri. A ajiye danshi a saman ƙasa da kashi 0.1% domin hana tsatsa.

III. Zaɓi Shafi Mai Dacewa: Gina Kariya Mai Launi Da Yawa
Rufin shine babban kariya ga Coil Ppgl. Lokacin zabar tsarin rufi, yi tunani game da juriyar yanayi, juriyar sinadarai, da mannewa:
1. Zaɓi Farar Gilashi: Farar Gilashin Epoxy suna da kyau saboda suna mannewa sosai kuma suna toshe abubuwan da ke lalata su. Don matsalolin da ake buƙata, yi amfani da farar Gilashin Polyurethane don sa murfin ya fi sassauƙa kuma ya jure wa feshin gishiri.
2. Zaɓi Topcoat: Zaɓi fenti mai jure yanayi.
– Ga muhalli na yau da kullun: Rigunan polyester masu jure wa yanayi mai zafi zaɓi ne mai kyau. Suna jure wa UV da tsufa sosai kuma ba su da tsada sosai.
– Ga muhalli masu tauri (kamar yankunan ruwa ko masana'antu): Rufin rufin PVDF (polyvinylidene fluoride) ya fi kyau. Suna da juriya sosai ga yanayi da sinadarai kuma suna iya ɗaukar sama da shekaru 20.
3. Kula da Kauri na Rufi: Ya kamata faramin ya kasance kauri 5-7μm, saman rufin kuma ya kasance 15-20μm. Jimillar kauri na rufi ya kamata ya zama aƙalla 25μm don guje wa matsaloli kamar ramukan ramuka.
IV. Bi Kyakkyawan Samarwa da Shigarwa: Guji Tsatsa daga Kurakurai
Ko da kwal ɗin Galvalume mai inganci da aka riga aka fenti zai iya rasa juriyarsa ta tsatsa idan aka sarrafa shi ba daidai ba:
1. Sarrafa Tsarin Rufewa: Yi amfani da murfin nadi don daidaita murfin. A kiyaye zafin da ke warkewa a 230 - 250℃ na tsawon daƙiƙa 30 - 60. Wannan yana hana murfin ya yi rauni sosai.
2. Kare Yayin Shigarwa:
– Kada ka goge saman murfin PPGL. Gyara karce da fenti na musamman nan take.
– A bar haɗin faɗaɗawa yayin shigarwa don hana murfin fashewa saboda canjin yanayin zafi.
– A yankunan bakin teku ko danshi, yi amfani da maƙallan ƙarfe na bakin ƙarfe don guje wa tsatsa daga ƙarfe daban-daban da ke taɓawa.
V. Kulawa A Kai-tsaye: Sa Na'urar Ta Daɗe Tana Daɗewa
Gyara akai-akai na iya rage tsatsa, musamman ga murfin ƙarfe na Galvalume na waje:
1. Tsaftace Sau da Yawa: Tsaftace na'urar da ruwa ko sabulun wanke-wanke mai tsaka tsaki aƙalla sau 1-2 a shekara. Wannan yana cire ƙura, gishiri, da sauran datti waɗanda zasu iya haifar da tsatsa.
2. Gyara Lalacewa Da Sauri: Idan akwai wani ƙage ko lalacewa a kan murfin, yi amfani da fenti mai dacewa nan da nan don hana abubuwa masu lalata shiga ƙarƙashin ƙasa.
3. A ware daga Muhalli: Ga na'urori masu kama da acid ko alkali ko kuma a gefen teku, a yi amfani da shingen kariya ko rufin kariya don rage hulɗa da abubuwa masu lalata.
