Utsi chitoliro ndi chigawo chofunikira cha njinga yamoto, amene kupanga kutentha kwambiri pa ntchito.Kupopera penti kumatha kuteteza gawo lapansi ku dzimbiri.Chifukwa chogwiritsa ntchito kunja kwa nthawi yaitali, chitoliro chotulutsa mpweya chidzawonetsedwa ndi mphepo ndi mvula, zomwe zidzapangitse dzimbiri pamwamba, osati kukhudza maonekedwe okha, komanso kulowa mu gawo lapansi.

Zovala zolimbana ndi kutentha kwambiri zimafunikira pakupaka chitoliro chamoto chamoto choletsa dzimbiri, ndipo utoto wamba monga utoto wa epoxy ndi utoto wa polyurethane umakhala wopanda kutentha ndipo sungathe kukwaniritsa zofunika kutentha.W61-650 kutentha kugonjetsedwa ndi utoto angagwiritsidwe ntchito poteteza odana ndi dzimbiri ya dongosolo utsi chitoliro, amene ali ndi chitetezo zotsatira zabwino kwambiri pa kutopa chitoliro.

Utoto wa W61-650 wotentha kwambiri umatha kukana kutentha kwa 600 ℃, filimu ya utoto sikophweka kusintha mtundu, imakhala ndi kukana kozizira kwambiri komanso kotentha panjinga, imakhala ndi zida zabwino zamakina pambuyo pakupanga filimu, komanso kumamatira mwamphamvu ku gawo lapansi.Utoto ukhoza kupopera ndi dzanja kapena kupopera mankhwala pogwiritsa ntchito electrostatic mumzere wa msonkhano, womwe uli woyenera njira zosiyanasiyana zopenta.Pamwamba pa zinthu m'munsi ayenera kuchitiridwa bwino, ndi banga mafuta, okusayidi khungu, dzimbiri, ❖ kuyanika akale, etc. adzachotsedwa ndi kuphulika mchenga kufika muyezo Sa2.5 dzimbiri kuchotsa, ndipo roughness adzafika 35-70. μm m.Pambuyo pa sandblasting, imatha kuonetsetsa kuti imamatira bwino ndikutalikitsa moyo wautumiki wa zokutira.

The njinga yamoto utsi chitoliro makamaka opangidwa ndi mpweya zitsulo ndi zitsulo zosapanga dzimbiri.Utoto wa W61-510 wotentha kwambiri ukhoza kugwiritsidwa ntchito popaka utoto wosasunthika wachitsulo chosapanga dzimbiri.Imamatira bwino kugawo lachitsulo chosapanga dzimbiri komanso kukana kutentha kwambiri.Pamwamba pazitsulo zosapanga dzimbiri sizifuna kuphulika mchenga.Ikhoza kutsukidwa ndi zosungunulira kuchotsa madontho a mafuta pamwamba.Mankhwala apamwamba ndi osavuta.
