Oyamba ambiri amagwera mumsampha akamagula masikono okutidwa ndi utoto chifukwa samamvetsetsa zinthu zawo. Ndiye, ndi zinthu ziti zomwe zili zabwino pamipukutu yopaka utoto?
Gawo laling'ono la ma koyilo opaka utoto amatha kukhala ma coils ozizira kapena zitsulo zovimbidwa ndi electroplated. Ngakhale kuti zokutira zamtundu wa coil zamitundu zimakhala ndi zotsatira zabwino zotsutsana ndi dzimbiri, pali mipata yaying'ono mu zokutira za organic, zomwe zimatha kulola mpweya ndi chinyezi kulowa ndikuyambitsa dzimbiri la gawo lapansi. Chifukwa chake, zotchingira zamitundu yopangidwa kuchokera ku magawo osakutidwa zimakhala ndi moyo waufupi wautumiki ndipo sachedwa kufalikira komanso kupemba pambuyo pokanda. The gawo lapansi la mtundu TACHIMATA zitsulo koyilo makamaka kanasonkhezereka zitsulo mbale kapena kanasonkhezereka zitsulo aloyi kwa luso mbale zitsulo. M'mizere ina yopangira, kupanga zokutira zamitundu kumagawika m'malo ochiritsira kale, zokutira zosinthira mankhwala (zopaka zitsulo zosakhala organic), zokutira zopanda chitsulo, ndi zokutira positi.

1, gawo lapansi chisanadze mankhwala: Ngati sife kampani kuti mwachindunji kulowa mtundu ❖ kuyanika ndondomeko anthu pambuyo kupanga, kanasonkhezereka mbale zitsulo ntchito monga gawo lapansi akhoza mosalekeza dzimbiri (dzimbiri woyera), fumbi, ndi kuipitsidwa kwina pa mayendedwe ndi chitukuko. . Ngati izi sizingachotsedwe, khalidwe la utoto lidzakhudzidwa. Ubwino wa mipukutu yomalizidwa yamitundu yomalizidwa komanso luso lakuthupi ndi laukadaulo la ophunzira onse ndizogwirizana kwambiri ndi chithandizo chamankhwala chisanadze. Kuonjezera apo, popanga galvanizing, pofuna kupewa dzimbiri ndi mafuta, mafutawa amachotsedwanso asanapange kupaka utoto. Njira yomwe imagwiritsidwa ntchito nthawi zambiri isanalandire chithandizo tsopano ndi njira yochepetsera ya alkaline solution.
2. The mankhwala kutembenuka filimu ali ndi ntchito ziwiri
Chimodzi ndicho kupititsa patsogolo luso lopewa dzimbiri,
Chachiwiri ndikuwongolera kumamatira pakati pa gawo lapansi ndi zokutira, ndikuwongolera magwiridwe antchito a gawo lapansi.

Nthawi zambiri pali njira zitatu:
Imodzi ndi phosphating, yomwe poyamba imapanga makristasi ambiri pamtunda wachitsulo, kenako imapanga filimu ya phosphate pamwamba pazitsulo ndi mchere wa phosphate;
Chachiwiri ndi kungosiya ndi kusindikiza. Filimu ya phosphate idakali ndi ma pores, omwe amapangidwa ndi mankhwala ndi ma chromates kupanga filimu yoteteza. Chachitatu, sambani ndi madzi oyera ndikuchotsa njira yothetsera vutoli ndi madzi a desalinated kapena deionized.
3, zokutira za organic zimagawidwa kukhala zoyambira ndi topcoat. Zofunikira zoyambira sizokwera ndipo zitha kugwiritsidwa ntchito mwanjira yosalala. Komabe, pofuna kupititsa patsogolo chitetezo chazidziwitso zopanga, mabizinesi aku China nthawi zambiri amagwiritsa ntchito njira yosinthira utoto poyambira ndi topcoat.
Ndondomeko yokutira positi: Njira yokutira positi imaphatikizapo kusindikiza, kujambula, filimu yotetezera yotetezera, kugwirizanitsa, ndi zina zotero, zomwe zimathandizira kukongoletsa ndi kutetezedwa kwa bolodi lopaka utoto.
