Kusiyana pakati pa malata amagetsi ndi malata otentha

Magetsi amphamvu:
Chitsulo n'chosavuta kuchita dzimbiri mumlengalenga, m'madzi kapena m'nthaka, kapena kuonongeka.Kutayika kwachitsulo kwapachaka chifukwa cha dzimbiri kumapanga pafupifupi 1/10 ya zitsulo zonse.Kuonjezera apo, kuti apereke pamwamba pazitsulo zazitsulo ndi zigawo ntchito yapadera, ndikuwapatsa mawonekedwe okongoletsera, nthawi zambiri amathandizidwa ndi electro-galvanizing.

① Mfundo:
Popeza nthaka si kophweka kusinthasintha mu mpweya wouma, mu mpweya chinyezi, pamwamba akhoza kupanga wandiweyani kwambiri m'munsi-mtundu carbonate filimu, amene angathe kuteteza mkati salinso dzimbiri.

② Makhalidwe amachitidwe:

1. Chophimba cha zinki ndi chokhuthala, chokhala ndi makhiristo abwino, ofanana komanso opanda porosity, komanso kukana kwa dzimbiri bwino;
2. Zosanjikiza zinki zomwe zimapezedwa ndi electroplating zimakhala zoyera, ndipo zimawononga pang'onopang'ono mumkungu wa asidi, alkali, ndi zina zotero, ndipo zimatha kuteteza gawo lapansi lachitsulo;
3. Kupaka kwa zinki kumadutsa ndi chromic acid kuti apange zoyera, zokongola, zobiriwira zankhondo, ndi zina zotero, zomwe zimakhala zokongola komanso zokongoletsa;
4. Chifukwa chophimba cha zinc chimakhala ndi ductility chabwino, chimatha kupangidwa ndi kuzizira kozizira, kupukuta, kupindika, etc. popanda kuwononga chophimba.

③ Kuchuluka kwa ntchito:
Ndi chitukuko cha sayansi ndi luso kupanga, minda zomwe zikugwira ntchito mu makampani electroplating achulukirachulukira.Pakalipano, kugwiritsa ntchito electro-galvanization kwafalikira m'madipatimenti osiyanasiyana opanga ndi kafukufuku.

Hot malabati:
Ⅰ.Mwachidule:
Mu njira yokutira yamitundu yosiyanasiyana yotetezedwa yachitsulo, kuviika kotentha ndikwabwino kwambiri.Ndi mu boma kumene nthaka ndi madzi, pambuyo ndi zovuta fiziki, mankhwala, osati thicker koyera nthaka wosanjikiza osati yokutidwa pa zitsulo, komanso nthaka wosanjikiza achitsulo.Njira yopukutira iyi sikuti imangokhala ndi kukana kwa dzimbiri kwa galvanization yamagetsi, komanso chifukwa chakusanjikiza kwachitsulo chachitsulo.Ilinso ndi kukana kwambiri kwa electroplated zinc.Choncho, plating njira imeneyi ndi yoyenera makamaka ku malo owononga kwambiri monga mitundu yosiyanasiyana ya asidi amphamvu, mchere wamchere.
Ⅱ.Mfundo Yofunika:
Kutentha-kuviika kanasonkhezereka wosanjikiza ndi zinki mu kutentha madzi madzi, ndipo amapangidwa ndi masitepe atatu:
1. Malo opangidwa ndi chitsulo amasungunuka ndi njira ya zinki kuti apange gawo la zinc-ferrous;
2. Zinc ions mu aloyi wosanjikiza amafalikiranso ku gawo lapansi kuti apange zinki chitsulo intercollation wosanjikiza;
3. pamwamba pa aloyi wosanjikiza watsekedwa mu nthaka wosanjikiza.
Ⅲ.Makhalidwe amachitidwe:
(1) Lili ndi zovundikira zokhuthala kwambiri za zinki pamwamba pa chitsulo, zomwe zimapewa kukhudzana kwa matrix achitsulo kunjira iliyonse ya dzimbiri kuteteza matrix achitsulo kuti asawonongeke.Mu chilengedwe chonse, pamwamba pa nthaka wosanjikiza amapanga wosanjikiza woonda ndi wapamtima zinc oxide wosanjikiza, amene ndi kovuta kusungunula m'madzi, kotero zitsulo masanjidwewo amachita zoteteza.

(2) Ndi chitsulo-zinki aloyi wosanjikiza, kuphatikiza wandiweyani, mu nyanja mchere humex mlengalenga ndi mafakitale m'mlengalenga anasonyeza kukana dzimbiri wapadera;

(3) Popeza kuphatikiza kwake kuli kolimba, zinc-iron imasungunuka, imakhala ndi kukana kolimba;

(4) Popeza nthaka imakhala ndi ductility yabwino, alloy wosanjikiza amamangiriridwa motetezeka ku gulu lazitsulo, kotero kuti zigawo zotentha zotentha zimatha kuzizira, kukulunga, kupukutidwa, kupindika, ndi zina zotero popanda kuwononga zokutira;

(5) Pambuyo kutentha galvanization wa zitsulo finisse, ndi lofanana ndi annealing mankhwala, amene angathe bwino kusintha mawotchi katundu wa masanjidwewo zitsulo, kuthetsa nkhawa zitsulo akamaumba kuwotcherera, amene n'kopindulitsa kutembenuza zitsulo structural membala.

(6) Pamwamba pa zidutswa pambuyo pa galvanization yotentha ndi yowala komanso yokongola.

(7) Zosanjikiza zoyera za zinki ndizosanjikiza kwambiri zamapulasitiki-pulasitiki-zokutidwa ndi malata otentha, omwe ali pafupi kwambiri ndi nthaka yoyera, ductility, kotero amatha kusinthasintha.

Ⅳ.Kuchuluka kwa ntchito:
Kugwiritsa ntchito hot-dip ghanely chitukuko cha chitukuko cha mafakitale ndi ulimi.Choncho, zinthu zotentha zotentha ndi mafakitale (monga zida zamakina, kukonza mafuta, kufufuza m'madzi, zitsulo, kutumiza magetsi, kumanga zombo, etc.), ulimi (monga: kukonkha), zomangamanga (monga madzi ndi gasi, wire set Tube, scaffolding, house, etc.), mlatho, zoyendera, etc. akhala akugwiritsidwa ntchito m'zaka zingapo zaposachedwa.
Popeza zopangira malata otentha zimakhala ndi mawonekedwe okongola, ntchito yabwino yokana dzimbiri, mawonekedwe ake akuchulukirachulukira.
