PPGI COIL/Chophimba Chitsulo Chokhala ndi Mtundu

1. Chiyambi chachidule

Chitsulo chopakidwa kale chimakutidwa ndi zinthu zachilengedwe, zomwe zimapangitsa kuti chikhale cholimba kwambiri komanso chikhale ndi moyo wautali kuposa chitsulo chopakidwa ndi galvanized.
Zitsulo zoyambira za pepala lachitsulo lopakidwa utoto woyambirira zimakhala ndi zokutidwa ndi alu-zinc zozizira, zopakidwa ndi electro-galvanized HDG komanso zokutidwa ndi alu-zinc zotentha. Ma coat omalizidwa a mapepala achitsulo opakidwa utoto woyambirira amatha kugawidwa m'magulu motere: polyester, silicon modified polyester, polyvinylidene fluoride, high-durability polyester, ndi zina zotero.
Njira yopangira yasintha kuchoka pa kuphika kamodzi mpaka kuphika kawiri, komanso kuphika katatu ndi katatu.
Mtundu wa pepala lachitsulo lopakidwa kale uli ndi mitundu yosiyanasiyana, monga lalanje, kirimu, buluu wakuda, buluu wa m'nyanja, wofiira wowala, wofiira wa njerwa, woyera wa m'nyanga, buluu wa porcelain, ndi zina zotero.
Mapepala achitsulo opakidwa kale amathanso kugawidwa m'magulu malinga ndi mawonekedwe awo pamwamba, monga mapepala opakidwa kale, mapepala ojambulidwa ndi mapepala osindikizidwa.
Mapepala achitsulo opakidwa kale amaperekedwa makamaka pazinthu zosiyanasiyana zamalonda kuphatikizapo zomangamanga, zida zamagetsi zapakhomo, mayendedwe, ndi zina zotero.

2. Mtundu wa kapangidwe ka zokutira
2/1: Phikani pamwamba pa pepala lachitsulo kawiri, phimbani pansi kamodzi, kenako phikani pepalalo kawiri.
2/1M: Phikani ndi kuphika kawiri pamwamba ndi pansi.
2/2: Phikani pamwamba/pansi kawiri ndikuphika kawiri.

3. Kugwiritsa ntchito mitundu yosiyanasiyana ya zokutira
3/1: Mphamvu yoletsa dzimbiri komanso kukana kukanda kwa chophimba chakumbuyo cha single-layer ndi yofooka, komabe, mphamvu yake yomatira ndi yabwino. Chitsulo chopakidwa kale chamtunduwu chimagwiritsidwa ntchito makamaka pa sandwich panel.
3/2M: Chophimba chakumbuyo chili ndi mphamvu yolimbana ndi dzimbiri, kukana kukanda komanso kugwira ntchito bwino popanga zinthu. Kupatula apo, chili ndi mphamvu yomatira bwino ndipo chimagwiritsidwa ntchito pa gulu limodzi ndi pepala la masangweji.
3/3: Mphamvu yoletsa dzimbiri, kukana kukanda ndi mphamvu yokonza zinthu za pepala lachitsulo lopakidwa kale ndi yabwino, kotero imagwiritsidwa ntchito kwambiri popanga mipukutu. Koma mphamvu yake yomatira ndi yofooka, kotero siigwiritsidwa ntchito ngati gulu la masangweji.
