Chimango cha mlatho chagalasi:
Mlatho wamalata, womwe umatchedwanso mlatho wamagetsi wamagetsi; Ambiri kumvetsa ngati kanasonkhezereka mlatho kuti ndi otentha-kuviika kanasonkhezereka mlatho, kwenikweni, n'kulakwa, ngati kanasonkhezereka chitoliro, kanasonkhezereka mlatho anawagawa mitundu iwiri, kutanthauza, ozizira kanasonkhezereka (magetsi kanasonkhezereka) ndi otentha-kuviika kanasonkhezereka (wotentha-kuviika kanasonkhezereka );
Chitsulo ndi zitsulo zimachita dzimbiri mosavuta mumpweya, m'madzi kapena m'nthaka, ngakhale kuonongeka. Kutayika kwachitsulo kwapachaka komwe kumachitika chifukwa cha dzimbiri kumapanga pafupifupi 1/10 ya zitsulo zonse. Kumbali ina, kuti apange zitsulo zopangidwa ndi zitsulo ndi zigawo zake zimakhala ndi ntchito yapadera pamtunda, ndikupereka mawonekedwe ake okongoletsera nthawi imodzi, choncho nthawi zambiri amachitiridwa njira yamagetsi yamagetsi.
1. Mfundo:
Chifukwa nthaka si kophweka kusintha mu mpweya wouma, ndi mu mpweya chinyezi, pamwamba akhoza kupanga wandiweyani kwambiri zofunika nthaka carbonate filimu, filimuyi angathe kuteteza mkati ku dzimbiri. Ndipo pamene chophimbacho chikuwonongeka pazifukwa zina ndipo maziko achitsulo sali aakulu kwambiri, zinki ndi matrix achitsulo amapanga microbattery, kotero kuti matrix achitsulo amakhala cathode ndipo amatetezedwa.
2. Kachitidwe Kachitidwe:
1) Kupaka kwa zinki ndikwambiri, crystallization ndi yabwino, yunifolomu ndipo palibe pores, komanso kukana kwa dzimbiri ndikwabwino;
2) Zinc wosanjikiza wopezedwa ndi electroplating ndi wangwiro ndipo amawononga pang'onopang'ono mu asidi ndi chifunga cha alkali, chomwe chingateteze bwino matrix achitsulo;
3) Zinc ❖ kuyanika wopangidwa ndi chromic acid passivation woyera, mtundu, asilikali wobiriwira, wokongola, ali ndi kukongoletsa zina;
4) Chifukwa zokutira zinki zimakhala ndi ductility zabwino, zimatha kuzizira, kugudubuza, kupindika ndi kupanga zina popanda kuwononga zokutira.
3. Kuchuluka kwa ntchito:
Ndi chitukuko cha sayansi ndi ukadaulo, makampani opanga ma electroplating amaphatikiza magawo ochulukirapo. Pakadali pano, kugwiritsa ntchito galvanizing kwachitika m'madipatimenti onse opanga ndi kafukufuku pazachuma cha dziko. Mwachitsanzo, kupanga makina, zamagetsi, zida zolondola, makampani opanga mankhwala, mafakitale opepuka, zoyendera, zida, mlengalenga, mphamvu ya atomiki, ndi zina zotero, ndizofunika kwambiri pachuma cha dziko.
Hot-kuviika kanasonkhezereka mlatho(mlatho wotentha wa zinc)
1, malongosoledwe a zinki otentha:
Hot dip zinc ndi imodzi mwa njira zabwino zokutira zotetezera gawo lapansi lachitsulo. Ndi mu madzi boma nthaka, pambuyo ndithu zovuta thupi ndi mankhwala kanthu, osati pa zitsulo plating thicker koyera nthaka wosanjikiza, komanso kupanga nthaka - chitsulo aloyi wosanjikiza. Njira yopangira iyi sikuti ili ndi mawonekedwe a kukana kwa dzimbiri kwa galvanizing, komanso ili ndi wosanjikiza wachitsulo-chitsulo. Ilinso ndi kukana kwamphamvu kwa dzimbiri komwe sikungafanane ndi galvanizing. Choncho, plating njira imeneyi ndi yabwino makamaka kwa mitundu yonse ya asidi amphamvu, alkali chifunga ndi zina amphamvu dzimbiri chilengedwe.
2. Mfundo:
Hot dip zinc wosanjikiza amapangidwa masitepe atatu pansi pa kutentha kwamadzimadzi:
1) chitsulo m'munsi pamwamba ndi kusungunuka ndi nthaka njira kupanga nthaka-chitsulo aloyi gawo wosanjikiza;
2) Ma ion a zinki mu aloyi wosanjikiza amafalikiranso ku masanjidwewo kuti apange zinki-chitsulo chosanjikizana;
3) Pamwamba pa aloyi wosanjikiza amatsekereza nthaka wosanjikiza.
3. Makhalidwe amachitidwe:
(1) Ndi wosanjikiza wandiweyani koyera zinki wosanjikiza pamwamba pa chitsulo, akhoza kupewa masanjidwewo zitsulo ndi njira dzimbiri kukhudzana, kuteteza zitsulo masanjidwewo kuti dzimbiri. Mu chilengedwe chonse, pamwamba pa nthaka wosanjikiza amapanga woonda kwambiri ndi wandiweyani okusayidi wosanjikiza pamwamba, n'zovuta kupasuka m'madzi, choncho amatenga mbali yoteteza pa masanjidwewo zitsulo. Ngati nthaka okusayidi ndi zigawo zina mu mlengalenga kupanga insoluble zinki mchere, dzimbiri chitetezo ndi abwino kwambiri.
(2) Pali chitsulo - nthaka aloyi wosanjikiza, yaying'ono, mu Marine mchere kutsitsi mumlengalenga ndi mafakitale m'mlengalenga ntchito wapadera dzimbiri kukana;
(3) Chifukwa cha kuphatikiza kolimba, zinki-chitsulo miscible, ndi kukana amphamvu kuvala;
(4) Chifukwa nthaka imakhala ndi ductility yabwino, wosanjikiza wake wa aloyi ndi zitsulo zomangika mwamphamvu, kotero zigawo zotentha zotentha zimatha kukhala kupondaponda kozizira, kugudubuza, kujambula, kupindika ndi mitundu ina popanda kuwononga zokutira;
(5) Pambuyo otentha-kuviika galvanizing mbali zitsulo structural, ndi lofanana ndi limodzi annealing mankhwala, amene angathe bwino kusintha mawotchi zimatha zitsulo masanjidwewo, kuthetsa nkhawa pa kupanga ndi kuwotcherera mbali zitsulo, ndi yabwino kwa kutembenuka. zigawo zazitsulo zamapangidwe.
(6) Pamwamba pa zowonjezera pambuyo pa kutentha kwa dip galvanizing ndizowala komanso zokongola.
(7) Koyera nthaka wosanjikiza kwambiri pulasitiki wosanjikiza wa otentha kuviika kanasonkhezereka wosanjikiza, katundu wake ali kwenikweni pafupi koyera nthaka, ductility, choncho kusintha.
4. Kuchuluka kwa ntchito:
Kugwiritsiridwa ntchito kwa dip dip galvanizing kumakula ndi chitukuko cha mafakitale ndi ulimi. Choncho, otentha-kuviika kanasonkhezereka mankhwala makampani (monga zida mankhwala, processing mafuta, Marine kufufuza, dongosolo zitsulo, kufala mphamvu, shipbuilding, etc.), ulimi (monga: ulimi wothirira, wowonjezera kutentha), zomangamanga (monga: madzi ndi Kutumiza kwa gasi, chosungira ma waya, scaffolding, nyumba, milatho, zoyendera, ndi zina zambiri, zakhala zikugwiritsidwa ntchito kwambiri m'zaka zaposachedwa zopangira malata a Hot-dip zimagwiritsidwa ntchito kwambiri chifukwa cha mawonekedwe awo okongola komanso kukana kwa dzimbiri.
Awiri, kusiyana pakatispray Bridgendimalata mlatho
Utsi mlatho ndi kanasonkhezereka mlatho zimangosiyana mu ndondomeko, specifications, zitsanzo, mawonekedwe ndi dongosolo la mlatho n'zofanana.
Kusiyana kwa ndondomeko pakati pa mlatho wa spray ndi mlatho wamalata:
Choyambirira,malata mlathondi pulasitiki kupopera mbewu mankhwalawa mlatho ndi zitsulo chingwe mlatho, kanasonkhezereka mlatho anapangidwa ndi kanasonkhezereka mbale zitsulo, kanasonkhezereka mbale ine ndikukhulupirira palibe chifukwa kufotokoza mochuluka, ndi pulasitiki kupopera mlatho ntchito pokonza wosanjikiza electrostatic kupopera wosanjikiza pamwamba. wa kanasonkhezereka mlatho, choncho amatchedwa pulasitiki kupopera mbewu mankhwalawa mlatho, kumvetsa yosavuta ndi kuti pulasitiki kupopera mbewu mankhwalawa Baibulo ndi Baibulo Mokweza la kanasonkhezereka mlatho, kukana dzimbiri ndi wamphamvu.
Ngati muli ndi chidwi ndi mankhwalawa, mutha kudina pakona yakumanja yakumanja, tidzakulumikizani posachedwa.
