Kodi Chophimba Chopangidwa ndi Galvanized "Chimasintha" Bwanji Kukhala Mtundu - Chophimba cha PPGI?

M'magawo ambiri monga zomangamanga ndi zida zapakhomo, ma PPGI Steel Coils amagwiritsidwa ntchito kwambiri chifukwa cha mitundu yawo yokongola komanso magwiridwe antchito abwino kwambiri. Koma kodi mukudziwa kuti "choyambirira" chake ndi Galvanized Steel Coil? Zotsatirazi zikuwonetsa momwe Galvanized Sheet Coil imapangidwira kukhala PPGI Coil.

1. Kumvetsetsa Ma Galvanized Coils ndi Ma PPGI Coils

Opanga Ma Galvanized Coils amapaka ma Galvanized coils ndi zinc pamwamba, zomwe zimapangitsa kuti chitsulo chisamavutike ndi dzimbiri ndipo zimawonjezera moyo wa ntchito ya chitsulo. Ma PPGI steel coils amagwiritsa ntchito ma galvanized steel coils ngati substrate. Pambuyo pokonza zinthu zingapo, ma organic coatings amaikidwa pamwamba pawo. Sikuti amangosunga dzimbiri ngati ma galvanized steel coils komanso amawonjezera zinthu zabwino kwambiri monga kukongola ndi kukana nyengo.

 

2. Njira Zopangira Zofunikira pa Fakitale ya Zitsulo Zopangidwa ndi Galvanized

(1) Njira Yokonzera Mafuta Asanagwiritsidwe Ntchito - Kuchotsa Mafuta: Pamwamba pa zitsulo zomangira zitsulo zokhala ndi galvanized zitha kukhala ndi zinthu zosafunika monga mafuta ndi fumbi. Zinthu zoipitsazi zimachotsedwa ndi njira za alkaline kapena mankhwala ochotsera mafuta kuti zitsimikizire kuti chophimba chotsatiracho chikugwirizana bwino ndi substrate. Mwachitsanzo, kugwiritsa ntchito njira yochotsera mafuta yokhala ndi surfactant kungathe kuwononga bwino mamolekyu a mafuta.

Chithandizo cha Kusintha kwa Mankhwala: Chofala kwambiri ndi chromization kapena chromium - free passivation treatment. Chimapanga filimu yopyapyala kwambiri ya mankhwala pamwamba pa galvanized layer, cholinga chake ndi kulimbitsa mgwirizano pakati pa substrate ndi utoto pamene ikupititsa patsogolo kukana dzimbiri. Filimu iyi ili ngati "mlatho", zomwe zimathandiza kuti utoto ulumikizidwe kwambiri ndi galvanized steel coil.

(2) Njira Yopaka Utoto - Kupaka Primer: Primer imagwiritsidwa ntchito pa galvanized coil yokonzedwa kale pogwiritsa ntchito roller coating kapena njira zina. Ntchito yayikulu ya primer ndikuletsa dzimbiri. Ili ndi utoto wotsutsana ndi dzimbiri ndi ma resin, omwe amatha kusiyanitsa bwino kukhudzana pakati pa chinyezi, mpweya, ndi galvanized layer. Mwachitsanzo, epoxy primer imakhala yolimba bwino komanso yolimba.

Chophimba cha Topcoat: Sankhani zophimba za topcoat zamitundu yosiyanasiyana komanso magwiridwe antchito ophikira malinga ndi zofunikira. Chophimba cha topcoat sichimangopatsa PPGI coil mitundu yowala komanso chimateteza monga kukana nyengo ndi kukana kukalamba. Mwachitsanzo, chophimba cha polyester chili ndi mitundu yowala komanso kukana bwino kwa UV, zomwe zimapangitsa kuti chigwiritsidwe ntchito panja. Zophimba zina zokhala ndi utoto wamitundu yosiyanasiyana zimakhalanso ndi utoto wakumbuyo kuti ziteteze kumbuyo kwa substrate kuti isawonongeke ndi chilengedwe.

(3) Kuphika ndi Kukonza Chingwe chachitsulo chopakidwa utoto chimalowa mu uvuni wophikira ndipo chimaphikidwa pa kutentha kwina (nthawi zambiri 180℃ - 250℃). Kutentha kwakukulu kumapangitsa utomoni mu utotowo kudutsa mu njira yolumikizirana, kuuma kukhala filimu ndikupanga chophimba cholimba. Nthawi yophikira ndi kutentha ziyenera kulamulidwa bwino. Ngati kutentha kuli kotsika kwambiri kapena nthawi sikokwanira, filimu ya utoto sidzachira kwathunthu, zomwe zimakhudza magwiridwe antchito; ngati kutentha kuli kokwera kwambiri kapena nthawi yayitali kwambiri, filimu ya utoto ikhoza kukhala yachikasu ndipo magwiridwe antchito ake angachepe.

(4) Kukonza Pambuyo (Mwasankha) Ma coil ena a PPGI Steel amakonzedwa pambuyo monga kukongoletsa, kukongoletsa, ndi zina zotero atatuluka mu uvuni. Kukongoletsa kumatha kukongoletsa pamwamba ndi kukangana, ndipo kukongoletsa kumatha kuteteza pamwamba pa chophimba panthawi yonyamula ndi kukonza kuti pasakhale mikwingwirima.

 

3. Ubwino ndi Kugwiritsa Ntchito Ma PPGI Steel Coils Kudzera mu ndondomeko yomwe ili pamwambapa, galvanized steel coil imasinthidwa bwino kukhala PPGI coil. PPGI Coil ndi yokongola komanso yothandiza. Pa ntchito yomanga, ingagwiritsidwe ntchito pa makoma akunja ndi madenga a mafakitale. Ndi mitundu yosiyanasiyana, ndi yolimba ndipo siitha. Pa ntchito ya zipangizo zapakhomo, monga mafiriji ndi zipolopolo za air-conditioner, zonse zimakhala zokongola komanso zosatha. Kugwira ntchito kwake bwino kwambiri kumapangitsa kuti ikhale yofunika kwambiri m'mafakitale ambiri. Kuyambira galvanized coil mpaka PPGI coil, kusintha komwe kumawoneka kosavuta kumaphatikizapo ukadaulo wolondola komanso njira yasayansi. Ulalo uliwonse wopanga ndi wofunikira kwambiri, ndipo pamodzi amapanga magwiridwe antchito abwino a PPGI coil, kuwonjezera mtundu ndi kusavuta kwa mafakitale amakono ndi moyo.
