Common mankhwala pretreatment
Zida zochizira chisanadze malinga ndi mawonekedwe a workpiece ndi voliyumu yosiyana yopanga, mawonekedwe akuluakulu amtundu wa impregnation, ngalande kudzera mumtundu wopopera; mtundu wa impregnation ndi woyenera mbali zazikulu, zopusa, monga kupanga mzere wosakhala waukulu kwambiri; ngalande kudzera mu mtundu wa kupopera ndi oyenera workpieces ang'onoang'ono ndi kupanga mizere lalikulu kupanga.
Zida zogwirizana:akasinja asanayambe chithandizo (zitsulo zosapanga dzimbiri kapena akasinja a konkire, chiwerengerocho ndi chofanana ndi chiwerengero cha njira zochizira), kupopera mbewu mankhwalawa.
Zogwirizana (mankhwala):sulfuric acid, hydrochloric acid, soda ash (Na2CO3) acidic degreasing agent, passivation solution.
Cholinga:Chotsani mafuta, fumbi, dzimbiri pamwamba pa workpiece, ndi kupanga wosanjikiza kukana dzimbiri padziko workpiece ndi kuonjezera adhesion wa kutsitsi ❖ ❖ kuyanika "mankwala wosanjikiza".
Njira zazikuluzikulu zoyendetsera:kuchepetsa, kuchotsa dzimbiri, kutsuka madzi, passivation. Workpiece pambuyo pretreatment sadzakhala ndi mafuta, dzimbiri, fumbi, ndi choyambirira siliva woyera glossy pamwamba kupanga wosanjikiza yunifolomu ndi akhakula zovuta dzimbiri imvi mankwala filimu, osati kupewa dzimbiri komanso kuonjezera adhesion wa ❖ kuyanika kutsitsi. .
Yankho lamadzi onyansa:Gwiritsani ntchito potion yosamalidwa bwino komanso chipangizo chamadzi otayira kuti mukwaniritse kutulutsa kokhazikika pambuyo pa chithandizo.
Kuchiza thupi kofala
Nthawi zambiri pali mitundu iwiri ya kuphulika kwa mchenga ndi kuwombera, palibe madzi otayira omwe amapangidwa, palibe chifukwa chodera nkhawa za chilengedwe.
Kuphulika kwa mchenga nthawi zambiri kumakhala koyenera pazidutswa zowonda kwambiri, kuphulitsa kuwombera nthawi zambiri kumakhala koyenera zida zokhuthala.
Lumikizanani ndi OURS COATING kuti mupange mzere wokonzeratu, ndife kusankha kwanu koyenera!
