Kodi mbale yachitsulo yopangidwa kale imapangidwa bwanji?

Chifukwa cha kuwonjezeka kwapang’onopang’ono kwa zitsulo zokutidwa ndi mitundu m’ntchito yomanga, chisamaliro cha anthu pa zitsulo zokutidwa ndi mitundu chikukulirakulirabe.

Malinga ndi ziwerengero zosakwanira: Mu 2016, ku China kumagwiritsa ntchito mbale zachitsulo zojambulidwa kale zinali pafupifupi matani 5.8 miliyoni.
Zitsulo zokhala ndi mitundu(omwe amadziwikanso kuti organic coated steel plates ndi zitsulo zokutidwa kale) amatchulidwa kutengera zitsulo zoyambira (zotchedwa substrates) zokutidwa ndi mitundu yosiyanasiyana.
Chitsulo chokhala ndi utoto ndi chinthu chomwe chimakhala ndi nthawi yayitali yopanga.Kuchokera kugudubuza kotentha mpaka kuzizira kozizira, kumakhala ndi makulidwe ake, m'lifupi ndi chitsanzo, ndiyeno kumangirira, kumangiriza ndi kuyanika mtundu kuti apange zokongola.pepala lopaka utoto.Njira zazikulu zopangira gawo lopaka utoto zikuphatikizapo: Njira yopangira mankhwala, kupaka, kuphika
1, Pretreatment ndondomeko
Ndiko makamaka njira yochotsera zonyansa ndi mafuta omwe amamangiriridwa pamwamba pambuyo pa kutsukidwa kwa gawo lapansi;ndikulandira mankhwala ophatikizika a oxidation ndi passivation kuti apange filimu yopangira mankhwala.Kanema wokonzekera bwino ndi njira yabwino yolimbikitsira kulumikizana pakati pa gawo lapansi ndi zokutira.
2, ndondomeko yokutira
Pakadali pano, njira yomwe imagwiritsidwa ntchito kwambiri pakupaka mayunitsi amitundu muzomera zazikulu zachitsulo ndi zokutira zodzigudubuza.Pereka ❖ kuyanika ndi kubweretsa utoto poto poto kuti ❖ kuyanika wodzigudubuza kudzera lamba wodzigudubuza, ndi makulidwe ena a chonyowa filimu anapanga pa ❖ kuyanika wodzigudubuza., Kenako tumizani filimu yonyowa iyi ku njira yokutira ya gawo lapansi. Mwa kusintha kusiyana kwa wodzigudubuza, kuthamanga ndi kuthamanga kwa wodzigudubuza, makulidwe a ❖ kuyanika akhoza kuwonjezereka kapena kuchepetsedwa mkati mwa mitundu ina; Ikhoza kujambulidwa mbali imodzi kapena mbali zonse ziwiri nthawi imodzi.Njirayi ndi yachangu komanso imakhala ndi magwiridwe antchito apamwamba.
3, Kuphika ndondomeko
Njira yophikayi makamaka imakhudza kuchiritsa kwa ❖ kuyanika pamwamba pa mbale yachitsulo, zomwe zikutanthauza kuti chophimbacho chimapangidwa ndi polycondensation, polyaddition, crosslinking ndi zina zomwe zimachitika pansi pa kutentha kwina ndi zina kudzera muzinthu zopangira filimu, zothandizira. filimu kupanga zinthu ndi wochiritsa.Njira yosinthira kuchokera kumadzi kupita ku solid.The ❖ kuyanika ndi kuphika ndondomeko imaphatikizapo ❖ kuyanika koyamba, kuphika bwino ❖ kuyanika ndi njira yofananira ndi gasi yoyaka.
4, Kukonzekera kotsatira kwazitsulo zojambulidwa kalepepala
Kuphatikizira embossing, kusindikiza, laminating ndi njira zina zochizira, kupaka phula kapena filimu yoteteza imatha kuwonjezeredwa, zomwe sizimangowonjezera mphamvu ya anti-corrosion ya mbale yokhala ndi utoto, komanso imateteza mbale yopaka utoto kuti isawonongeke panthawi yogwira kapena kukonza. .
