Chophimba cha Galvalume Chopakidwa Kale, chomwe chimatchedwanso Ppgl Coil kapena Ppgl Steel Coil, ndi chinthu chofunikira kwambiri pomanga makoma a makatani, nyumba zosungiramo zida, komanso mayendedwe ozizira. Kukana kwake dzimbiri kumakhudza moyo wa ntchito ya chinthucho, mtengo wokonza, komanso chitetezo. M'malo ovuta monga m'mphepete mwa nyanja ndi m'malo oipitsa mpweya m'mafakitale, kupeza njira zowonjezera kukana dzimbiri kwa Ppgl Steel ndi vuto lalikulu m'makampani. Nkhaniyi ikupereka njira zisanu zothandiza kutengera kugwiritsidwa ntchito kwenikweni padziko lonse lapansi.
I. Pangani Substrate Kukhala Yabwino: Chiyambi Chabwino cha Kukana Kudzimbiritsa
Kukana kwa dzimbiri kwa Ppgl Steel kumadalira gawo lake, gawo lopangidwa ndi zinc - aluminiyamu (Galvalume Coil).
1. Yang'anirani Zophimba: Chophimba Chachitsulo Chabwino cha Ppgl chimafuna kusakaniza koyenera kwa aluminiyamu (55%), zinki (43.4%), ndi silicon (1.6%). Silicon imathandiza kupanga gawo la alloy ndikuletsa gawo la zinki kuti lisatuluke. Chophimba cha zinki chopangidwa ndi aluminiyamu chiyenera kukhala osachepera 120 g/m² (mbali zonse ziwiri). M'madera a m'mphepete mwa nyanja omwe amawononga kwambiri, imatha kupitirira 150 g/m² kuti ipange gawo loteteza lamphamvu.
2. Sankhani Substrate Yoyera: Substrate ya Ppgl Steel iyenera kukhala ndi zinthu zochepa monga carbon ndi sulfure. Izi zimachepetsa zolakwika zazing'ono ndikuletsa dzimbiri kuti lisayambe. Ndi bwino kugwiritsa ntchito zinthu zopangidwa ndi aluminiyamu zomwe zimakwaniritsa miyezo ya ASTM A792 kuti muchepetse chiopsezo cha dzimbiri.
II. Konzani Chitsime Chapamwamba: Konzani Kumatira Kwake
Kumatirira kwa Prepainted Galvalume Steel Coil kumakhudza kukana kwake dzimbiri. Kukonza bwino pamwamba ndikofunikira kwambiri:
1. Tsukani mu Masitepe Atatu: Chotsukiracho chiyenera kutsukidwa ndi alkaline kuti chichotse mafuta, kutsukidwa ndi asidi kuti chichotse dzimbiri, ndikutsukidwa kuti chichepetse dzimbiri. Izi zimaonetsetsa kuti pamwamba pake pali poyera ndipo zimaletsa "kutupa kwa intercalation" pakati pa chophimbacho ndi chotsukiracho.
2. Sinthani Passivation: Gwiritsani ntchito chromate passivation kapena chromium - free passivation (zomwe zili bwino kwa chilengedwe). Izi zimapanga filimu yofanana ya passivation pa Galvalume Steel Coil substrate. Zimathandiza kuti chophimbacho chizimamatira bwino ndikutseka zinthu zowononga.
3. Umitsani Bwino: Mukamaliza kukonza, umitsani nthaka mwachangu. Sungani chinyezi pamwamba pa nthaka pansi pa 0.1% kuti mupewe dzimbiri.

III. Sankhani Chophimba Choyenera: Pangani Chitetezo Cha Zigawo Zambiri
Chophimbacho ndiye chitetezo chachikulu cha Coil Ppgl. Mukasankha njira yophimba, ganizirani za kukana nyengo, kukana mankhwala, ndi kumatirira:
1. Sankhani Primer: Ma primer a epoxy ndi abwino chifukwa amamatira bwino ndikutseka zinthu zowononga. Pazinthu zofunika kwambiri, gwiritsani ntchito ma primer a polyurethane kuti chophimbacho chikhale chofewa komanso cholimba ku mchere.
2. Sankhani Topcoat: Sankhani zokutira zolimba zomwe sizikutentha ndi nyengo.
– Kwa malo abwinobwino: Ma polyester topcoats osapsa ndi nyengo yabwino ndi chisankho chabwino. Amalimbana ndi UV komanso kukalamba bwino ndipo si okwera mtengo kwambiri.
– Pa malo ovuta (monga m'madzi kapena m'mafakitale): Ma topcoat a PVDF (polyvinylidene fluoride) ndi abwino kwambiri. Amalimbana kwambiri ndi nyengo ndi mankhwala ndipo amatha kukhala zaka zoposa 20.
3. Yang'anirani Kukhuthala kwa Chophimba: Chophimbacho chiyenera kukhala ndi makulidwe a 5 - 7μm, chophimba chapamwamba 15 - 20μm. Kukhuthala konse kwa chophimbacho kuyenera kukhala osachepera 25μm kuti tipewe mavuto monga ma pinholes.
IV. Tsatirani Kupanga ndi Kukhazikitsa Kwabwino: Pewani Kudzimbidwa ndi Zolakwa
Ngakhale cholembera cha Galvalume chopakidwa kale chapamwamba kwambiri chingataye kukana kwake dzimbiri ngati sichikonzedwa bwino:
1. Yang'anirani Njira Yophikira: Gwiritsani ntchito chophikira chozungulira kuti chophimbacho chikhale chofanana. Sungani kutentha kophikira pa 230 - 250℃ kwa masekondi 30 - 60. Izi zimateteza chophimbacho kuti chisasweke kwambiri.
2. Tetezani Panthawi Yoyika:
– Musakanda pamwamba pa PPGL Coil. Konzani mikwingwirima ndi utoto wapadera wokonzanso nthawi yomweyo.
- Siyani malo olumikizirana poika kuti chophimbacho chisasweke chifukwa cha kusintha kwa kutentha.
– M'madera a m'mphepete mwa nyanja kapena m'malo onyowa, gwiritsani ntchito zomangira zosapanga dzimbiri kuti mupewe dzimbiri chifukwa cha kukhudza zitsulo zosiyanasiyana.
V. Sungani Nthawi Zonse: Pangani Coil Kukhala Yaitali Kwambiri
Kukonza nthawi zonse kungathandize kuchepetsa dzimbiri, makamaka pa Galvalume Steel Coil yakunja:
1. Tsukani Kawirikawiri: Tsukani chozunguliracho ndi madzi kapena sopo wosalowererapo osachepera kamodzi mpaka kawiri pachaka. Izi zimachotsa fumbi, mchere, ndi dothi lina lomwe lingayambitse dzimbiri.
2. Konzani Zowonongeka Mwachangu: Ngati pali mikwingwirima kapena kuwonongeka kwa utoto, gwiritsani ntchito utoto wofananira nthawi yomweyo kuti zinthu zowononga zisafike pansi pa nthaka.
3. Dzipatuleni ku Zachilengedwe: Pa ma coils omwe ali pafupi ndi magwero a asidi kapena alkali kapena m'mphepete mwa nyanja, gwiritsani ntchito zotchinga kapena zokutira zoteteza kuti muchepetse kukhudzana ndi zinthu zowononga.
