Chithandizo chapamwamba

Choyamba, tiyenera kudziwa chifukwa chake malonda amafunikira chithandizo chapamwamba, ntchito yake ndi chiyani, ndipo amathetsa vuto liti.

Choyambirira, njira yothandizira pamwamba pakupanga gawo lapansi pamwamba pa gawo lapansi lomwe ndi losiyana ndi makina, thupi ndi mankhwala a gawo lapansi. Cholinga cha chithandizo chapamwamba ndikukumana ndi kukana kwa dzimbiri, kuvala, kukongoletsa kapena zofunikira zina zofunikira.

Makasitomala ambiri amatifunsa chifukwa chomwe timafunikira chithandizo chapamwamba, ntchito yake ndi chiyani, ndipo ndichifukwa chiti chowonjezera njirayi?

Ogwira ntchito zaukadaulo a Ouzhan:Zinthu mopupuluma ndikuchotsa mitundu yonse yazinthu zakunja (monga mafuta, dzimbiri, fumbi, kanema wakale wa utoto, ndi zina zambiri) zolumikizidwa pamwamba pa chinthucho, ndikupatsanso gawo loyenera loyenera kutsata kuti liwonetsetse kuti pepala lokutira ali ndi chitetezo chabwino. Dzimbiri, magwiridwe antchito okongoletsa ndi ntchito zina zapadera, pamwamba pa chinthucho amayenera kukonzekereratu asanajambule. Ntchito yothandizidwa ndi mtundu uwu wamankhwala amatchulidwa kuti chithandizo cha pre-paint (pamwamba) kapena (pamwamba) chithandizo.

Chithandizo chapamwamba chimalimbikitsa kulimba ndi kukana kwa mankhwala. Pachiyambi, zimawonjezera nthawi yogwiritsira ntchito ndikusunga nthawi yambiri, mtengo ndi ndalama.

NJIRA YOPHUNZIRA Magetsi

Njirayi imagwiritsa ntchito ma elekitirodi kuti apange zokutira pamwamba pake. Njira zazikulu ndi izi:

(1) Kusankha kwamagetsi

Mu yankho la electrolyte, workpiece ndi cathode. Njira yopangira zokutira pamwamba pachitetezo chamtundu wakunja imatchedwa electroplating. Mzere wokutira ukhoza kukhala chitsulo, aloyi, semiconductor kapena wokhala ndi ma particles olimba osiyanasiyana, monga zokutira zamkuwa ndi ma nickel.

(2) Kutsekemera

Mu yankho la electrolyte, workpiece ndiye anode. Njira yopangira okusayidi pamwamba pachitetezo chamtundu wapano imatchedwa anodization, monga anodization of aluminium alloy.
Chithandizo cha okosijeni chachitsulo chitha kuchitika ndi mankhwala kapena njira zamagetsi. Njira yamagetsi ndiyo kuyika chogwirira ntchitoyo mu njira ya oxidizing, ndikudalira zochita zamankhwala kuti apange kanema wa oxide pamwamba pa workpiece, monga blueing of iron.

KUKUMIKIRA CHIKHALIDWE

Njirayi ilibe kanthu pakadali pano, ndipo imagwiritsa ntchito kulumikizana kwa zinthu zamankhwala kuti apange zokutira pamwamba pantchitoyo. Njira zazikulu ndi izi:

(1) Chithandizo chamakina chosinthira

Mu yankho la electrolyte, chitsulo chogwirira ntchito sichikhala ndi zochita zina zakunja, ndipo mankhwala omwe ali munjirayo amalumikizana ndi chojambulacho kuti apange zokutira pamwamba pake, zomwe zimatchedwa mankhwala osinthira makanema. Monga bluing, phosphating, passivation, ndi chromium mchere wothandizira pazitsulo.

(2) Kupaka kopanda magetsi

Mu yankho la electrolyte, pamwamba pa workpiece imathandizidwa popanda kuthandizira pakadali pano. Pothetsera vutoli, chifukwa chakuchepetsa kwa mankhwala, njira yoyika zinthu zina pamwamba pa chopangira ntchito kuti ipangidwe ndiyotchedwa ma electroless plating, monga electroless nickel, ma electroless copper plating, ndi zina zambiri.

KUKUMIKIRA KUTENTHA KWAMBIRI

Njira iyi ndi kusungunula kapena kutentha kwambiri zinthuzo pansi pamawonekedwe otentha kwambiri kuti apange zokutira pamwamba pantchitoyo. Njira zazikulu ndi izi:

(1) Hot kuviika plating

Njira yoyika chitsulo chosungunuka muchitsulo chosungunuka kuti apange zokutira pamwamba pake amatchedwa zotchinga zotentha, monga zotenthetsera-kutentha ndi zotayirira zotentha.

(2) matenthedwe kupopera
Njira yopangira chitsulo chosungunuka ndikuipopera pamwamba pa chopangira ntchito kuti ipangidwe ndimatenthedwe otentha, monga kupopera matenthedwe nthaka ndi zotayirira zotentha.

(3) Kupondaponda
Njira yotenthetsera ndi kukanikiza zojambulazo zachitsulo kuti ziphimbe pamwamba pa chopangira ntchito kuti apange zokutira zotchedwa kutentha kosamphuka, monga kupondaponda kotentha kwa aluminiyamu.

(4) Chithandizo cha kutentha kwa mankhwala
Njira yomwe workpiece imalumikizana ndi zinthu zamankhwala ndikutenthedwa, ndipo chinthu china chimalowa pamwamba pa chopangira ntchito kutentha kwambiri chimatchedwa mankhwala othandizira kutentha, monga nitriding ndi carburizing.

(5) Kuyang'ana
Mwa kuwotcherera, njira yokhazikitsira chitsulo chomwe chidayikidwa pamwamba pa chopangira chopangira chopangira chotchinga chimatchedwa kuwonekera, monga kuwotcherera kotsekemera ndi ma alloys osavala.

KULAMBA NJIRA YA VACUUM

Njirayi ndi njira yomwe zida zimapangidwira kapena kuyika ma ion ndikuyika pamwamba pa workpiece pansi pazitsulo kuti apange zokutira. Njira yayikulu ndi.

(1) Kutulutsa kwa nthunzi (PVD)

Pazinthu zopumira, njira yopangira chitsulo mu maatomu kapena mamolekyulu, kapena kuyiyika mu ayoni, imayikidwa mwachindunji pamwamba pa malo ogwirira ntchito kuti ipange zokutira, zomwe zimatchedwa kuti nthunzi. Dothi lomwe laikidwa limachokera kuzinthu zosagwiritsa ntchito mankhwala, monga evaporation Sputtering plating, ion plating, ndi zina zambiri.

(2) Kuikika kwa Ion

Njira yopangira ma ion osiyanasiyana pamwamba pa workpiece pansi pamagetsi apamwamba kuti isinthe pamwamba amatchedwa kuyika kwa ion, monga jekeseni wa boron.

(3) Chemical Vapor Deposition (CVD)

Mukapanikizika pang'ono (nthawi zina kupanikizika kwanthawi zonse), momwe zinthu zamagesi zimakhalira zolimba pamwamba pa malo ogwirira ntchito chifukwa chamachitidwe am'madzi amatchedwa kutulutsa kwamadzi, monga kutulutsa kwa mpweya wa silicon oxide ndi silicon nitride.

NJIRA ZINA ZOKHUDZA

Makamaka makina, mankhwala, ma electrochemical, ndi njira zakuthupi. Njira zazikulu ndi izi:

Kujambula

Njira yopanda utsi kapena kutsuka ndiyo kugwiritsa ntchito utoto (organic kapena zochita kupanga) pamwamba pa chopangira ntchito kuti apange zokutira, zotchedwa kupenta, monga kujambula, kujambula, ndi zina zambiri.

Impact plating

Njira yopangira zokutira pamwamba pa chopangidwacho ndi mawonekedwe amakina amatchedwa kukongoletsa, monga kukhudzanso kwa galasi.

Chithandizo chamtundu wa Laser

Njira yowunikira pamwamba pa workpiece ndi laser kuti isinthe mawonekedwe ake amatchedwa chithandizo chamtundu wa laser, monga kuzimitsa laser ndikukonzanso kwa laser.

Ukadaulo wapamwamba

Ukadaulo wokonzekeretsa kanema wolimba kwambiri pamwamba pa chojambulacho pogwiritsa ntchito njira zakuthupi kapena zamankhwala amatchedwa ukadaulo wolimba kwambiri wamafilimu. Monga daimondi filimu, kiyubiki boron nitride filimu ndi zina zotero.

ELECTROPHORESIS NDI ELECTROSTATIC KUWALA

1. Electrophoresis

Monga elekitirodi, chojambuliracho chimayikidwa mu utoto wosungunuka m'madzi kapena wopaka madzi, ndikupanga dera limodzi ndi ma elekitirodi ena mu utoto. Pogwira ntchito yamagetsi, njira yovekera idasiyanitsidwa ndi ma resion ions, ma cations amasunthira ku cathode, ndipo anion amapita ku anode. Izi zotayidwa zamitengo, pamodzi ndi tinthu tating'onoting'ono tomwe timatulutsa, timasankhidwa ndi electrophores padziko lapansi kuti apange work kuyanika. Izi zimatchedwa electrophoresis.

2. Kupopera kwa Electrostatic

Mothandizidwa ndi DC yamagetsi yamagetsi yamagetsi yamagetsi, tinthu tating'onoting'ono tomwe timapanga ma atomized amayendetsedwa kuti aziwuluka pa chojambulidwa chotsimikizika kuti atenge kanema wopenta, womwe umatchedwa kupopera mankhwala.
