Mu bizinesi yokonza zitsulo, imodzi mwa mitu yomwe yakhala ikukambidwa mobwerezabwereza posachedwapa ndi nkhani yogwirizana pakati paGi Gl PPGIndi China Prepainted Aluzinc Steel Coil. Ogula ambiri, akamasankha ma coil achitsulo okhala ndi utoto, nthawi zambiri amakhala osatsimikiza akamaona mndandanda wautali wa zinthu zomwe zingagwiritsidwe ntchito.Chophimba Chitsulo Chokutidwa ndi Mtundu.
Ndipotu, mfundo yolumikizira iyi ndi yosavuta. Tiyeni titenge chitsanzo cha coil yachitsulo ya PPGL yomwe imapezeka pamsika. Mukaiwona, mudzamvetsa.
PPGL kwenikweni imayimira "kumaliza" pa galvalume (chitsulo chophimbidwa ndi aluminiyamu-zinc). Njira yake yopangira si yachinsinsi: maziko ake amachotsedwa mafuta ndikusintha kuti ayeretse bwino pamwamba pake, kenako amapaka utoto umodzi kapena zingapo, ndipo pamapeto pake amawotchedwa pa kutentha kwakukulu kuti akhazikitse mawonekedwe ake.
Kodi ubwino wochita izi ndi wotani?
Antchito ambiri odziwa bwino ntchito amadziwa kuti ngakhale kuti pepala la zinc lopangidwa ndi aluminiyamu silitha kudzimbidwa, limakhala ndi mavuto ngati lisiyidwa lotseguka kwa nthawi yayitali. Komabe, chophimba cha PPGL chachilengedwe chili ngati suti yotetezera coil yachitsulo. Chimaphimba mwamphamvu gawo la aluminiyamu-zinc ndipo ndi chokongola komanso chotha kuletsa mpweya ndi chinyezi kulowa.
Malinga ndi deta yochokera ku dipatimenti yaukadaulo ya ZZ Group, njira yotetezera iyi yokhala ndi zigawo ziwiri yathandiza kuti nthawi ya moyo wa Color Coated Steel CoilX ikhale yayitali nthawi 1.5 kuposa nthawi ya aluminiyamu wamba. Kwa opanga omwe amapanga nyumba zakunja kapena zipolopolo za zida, izi zikutanthauza kuchepetsa kwakukulu ndalama zokonzera.
Ponena za izi, tiyenera kutchula za Gulu la ZZ.
Mwina anthu ena atsopano omwe amadziwana nawo sakudziwa. Gulu la ZZ linayamba kugwira ntchito zake kumayambiriro kwa zaka za m'ma 1980, ndipo likulu lake lili ku Yangpu District, Shanghai. Popeza linkatha kukhazikitsa malo ake mu bizinesi yogulitsa zitsulo panthawiyo komanso kupitiriza kukula kuti likwaniritse ntchito yokonza zitsulo, zipangizo zopangira, malo ogulitsa nyumba, komanso ndalama zogulira, ndi ndalama zolembetsedwa za ma yuan 200 miliyoni, iyi ndi "mtundu wodziwika bwino" wamphamvu kwambiri mumakampaniwa.
Chinthu chachikulu chomwe akutsatsa panopa,China Prepainted Aluzinc Steel Coil, anatha kukwaniritsa miyezo molondola chifukwa ankamvetsa bwino miyezo ya Gi Gl PPGI. Kuyambira kulemera kwa wosanjikiza wa aluminiyamu-zinc wa maziko (40-275g/m²), mpaka ngati chophimba pamwamba ndi cha PE kapena PVDF, gawo lililonse linkachitidwa mosamala kwambiri.
Chifukwa chake, mukafuna chozungulira chokhala ndi utoto chomwe chingakwaniritse zofunikira zamphamvu komanso chosagonjetsedwa ndi dzimbiri panja, mungafune kuyang'ana PPGL. Si ukadaulo watsopano wosintha zinthu, koma pankhani ya "kulimba", chapita patsogolo kwambiri poyerekeza ndi zinthu zakale.
