Ukulungiswa kwamacandelo kunye nokuhluthwa kwe-hanger kwi-powder coating

Iindlela zokulungiswa kwenxalenye emva yengubo inokubekwa kwiindidi ezimbini: touch-up kunye ne-recoat.
Ukulungiswa kwe-Touch-up kuyafaneleka xa indawo encinci yecandelo elidibeneyo lingagqunywanga kwaye ayikwazi ukuhlangabezana neenkcukacha zokugqiba. Xa amanqaku e-hanger engamkelekanga, kufuneka ucofe phezulu. I-Touch-up nayo ingasetyenziselwa ukulungisa umonakalo omncinci ovela ekuphatheni, kwi-machining, okanye kwi-welding ngexesha lendibano.

I-recoat iyafuneka xa inxalenye ingavunywanga ngenxa yesiphene esikhulu somphezulu okanye xa i-touch-up ingamkelekanga. Kweli nqanaba, kukho iindlela ezahlukeneyo zokukhetha ekufuneka ziqwalaselwe ngononophelo. Ngokuqhelekileyo inxalenye ekhatywayo inokuphinda idibaniswe nesambatho sesibini. Enye inketho kukuhluba kunye nokupeyinta kwakhona inxalenye. Ukuhluba kunokucoca ii-hangers zenxalenye ukunika umhlaba olungileyo
ngenxa yokutshiza kwe-electrostatic.

GQIBEZELA

Ipeyinti ye-liquid touch-up isetyenziswe ngebrashi encinci, i-aerosol spray, okanye umpu ongenamoya. Ipeyinti yomiswe ngomoya. Inkqubo yokumisa inokukhawuleziswa ngebhaka eliphantsi lokushisa. Ipeyinti yokuchukumisa isetyenziswe emva kokuba i-powder powder iphiliswe ngokupheleleyo kwi-oven yokubhaka. Amanqaku e-Hanger, amabala akhanyayo kwiikona kunye ne-seams, umonakalo ovela kwi-welding okanye kwindibano, kunye nezinye iziphene ezincinci zingachukunyiswa. Generallilo, a umbala-ehambelana ne-acrylic enamel okanye i-lacquer isetyenziswa. Ipeyinti yokuchukumisa ayinakusetyenziswa ukuba ayiyi kuhlangabezana neenkcukacha zokusebenza ezifunekayo ngexesha lobomi obulindelekileyo belo candelo.
I-Touch-up akufanele isetyenziswe ukulungisa ukugqiba okuphosakeleyo ngaphandle kokuba imveliso ephumayo idibana nemigangatho yokuhlola.

RECOAT

Ukusebenzisa isambatho sesibini somgubo yindlela eqhelekileyo yokulungisa nokubuyisela iindawo ezikhatywayo. Nangona kunjalo, isiphene kufuneka sihlalutywe ngononophelo kwaye umthombo ulungiswe ngaphambi kokuba uphinde uhlaziywe. Musa ukuphinda uhlawule ukuba ukukhatywa kubangelwa isiphene sokwenziwa, i-substrate ekumgangatho ophantsi, ukucocwa kakubi okanye ukulungiswa kwangaphambili, okanye xa ubukhulu beengubo ezimbini kunye buya kuphelelwa ukunyamezela. Kwakhona, ukuba inxalenye yaliwe ngenxa yokungakhuseleki, kufuneka nje ihlawulwe kwishedyuli efunekayo.

Idyasi yesibini iyasebenza ukugquma iindawo ezikhanyayo, iziphene ezingaphezulu kukungcola kunye nokungcoliseka, amabala arhabaxa ukusuka kwifilimu enzima okanye ukutshicelwa kompu, kunye nokutshintsha kombala kwi-overbake enkulu. Umphezulu orhabaxa kunye neeprotrusions kufuneka zifakwe isanti egudileyo phambi kokuba ziphinde ziqatywe.

Amacandelo ahlolwe kwi-intanethi angashiywa kwi-conveyor ukufumana idyasi yesibini. La malungu angadlula kumanqanaba onyango lwangaphambili anamalungu akrwada. Ukuba iindawo ezihlaziyiweyo zibonisa amabala amanzi okanye amabala, ukulungiswa kunokwenziwa kwinqanaba lokugqibela lokuhlanjululwa.

Ababoneleli bemichiza banokunika iingcebiso. Xa iinxalenye ze-recoat zixhonywe kunye, ukucocwa kunye nokulungiswa kwangaphambili akuyimfuneko. Nangona kunjalo, ukuba iindawo ezikhatywayo zigcinwe ukuqokelela inani elisebenzayo, kufuneka zihlolwe ukungcola kunye nokungcola.

Idyasi yonke inxalenye

Xa usebenzisa isambatho sesibini, ubukhulu obuqhelekileyo be-mil kufuneka busetyenziswe kuyo yonke inxalenye. Impazamo eqhelekileyo kukugquma indawo yesiphene kuphela. Oku kushiya umphezulu orhabaxa apho kukho umaleko obhityileyo wokutshiza ngaphezulu kwenxalenye eshiyekileyo. Ishedyuli efanayo yokunyanga isetyenziselwa isambatho sesibini.

Ukuncamathela kwe-Intercoat kunokujongwa emva kokuphinda kuqatywe kwiisampulu ezikhethiweyo ngokusebenzisa uvavanyo lwe-hatch enqamlezileyo okanye ngokulula ukukrwela umphezulu ukubona ukuba idyasi yesibini ixobuka ngokulula kweyokuqala. Ezinye iingubo zomgubo zingadinga ukuba zenziwe ngesanti encinci ukuze zinike i-ankile efanelekileyo kwisambatho sesibini.

QHUBEKA

Xa inxalenye ingaphantsi ngexesha lengubo yokuqala, inokulungiswa ngokuyibuyisela kwi-oven yokubhaka kwishedyuli eqhelekileyo yonyango ngexesha elichaziweyo kunye nobushushu. Iipropathi ziya kufunyanwa kwakhona xa inxalenye inyangekile ngokufanelekileyo, ngaphandle kwezinye izinto, ezifana nezaleko ezithile ezilawulwa ngokwekhemikhali ezineglosi ephantsi. Unyango olungaphelelanga luya kubangela ukukhazimla okuphezulu, okungehliyo kwinqanaba elifanayo ngexesha lonyango lokugqibela oluya kuba lufunyenwe ngonyango olwaneleyo lokuqala.

UKUHLULA

Ukuhluba kudla ngokuba yeyona ndlela yokugqibela yokulungiswa kwenxalenye kuba ukuhlutywa kwemveliso eyaliweyo kunokongeza kakhulu kwiindleko zemveliso kwaye kuphazamise ukuhamba komgca wemveliso. Ukuhluthwa kwamalungu agqunyiweyo kuba yimfuneko, nangona kunjalo, xa ukwala kubangelwa kukunganyangeki kakuhle okanye xa i-touch-up okanye iidyasi ezimbini zingamkelekanga.
Ngakolunye uhlangothi, ukukrazula kudlala indima ebalulekileyo ekusebenzeni komgca wokugubungela umgubo ngokubonelela ngee-hangers ezicocekileyo kumhlaba omhle wombane. Ii-hangers kufuneka zihlulwe ngamaxesha athile. Iindlela zokukhulula zixutyushwa kule mihlathi ilandelayo. (Qaphela: Kukho umahluko kwimbono yokuba ukuhluthwa kweekhemikhali yeyona ndlela ikhethwayo.)

Izihluli zemichiza ziyafumaneka ukuba zisetyenziswe kushushu (ubushushu obunyusiweyo) okanye kubanda (kwitanki yokudipha). Kukho i-asidi, i-alkaline, kunye neentlobo zetyuwa ezinyibilikisiweyo, kunye nokukhethwa kuxhomekeke kuhlobo lwamalungu kunye nama-hangers kunye nokwaleka okuza kususwa.

Inzuzo ephambili yeekhemikhali strippers lutyalo-mali olusezantsi lwemali yokuqala yezixhobo. Izinto ezingeloncedo ziquka iingozi zokhuseleko lokuphatha imichiza, iindleko eziphezulu zokutshintshwa kweekhemikhali kunye nokulahlwa, kunye neekhemikhali ezilayishwe ipeyinti. Ezinye iindawo, ezinje ngealloyi zealuminiyam, zisenokungakwazi ukumelana nokugqwala kweekhemikhali.

Tshisa ucime

Ukutshisa, okanye i-pyrolysis, ii-oveni zokukhulula zisebenzisa amaqondo obushushu aphezulu ukutshisa i-coating. Zinokuba luhlobo lwebhetshi okanye ii-oveni ze-intanethi ezisebenza malunga ne-800 ° F (427 ″C), kunye nombhobho wokulawula ungcoliseko osebenza kumaqondo obushushu amalunga ne-1200-1300 ° F (649-704 ° C). Ii-oveni ezitshileyo ziphelisa ungcoliseko kunye neengxaki zokulahla. Zisebenza ngokufanelekileyo, kodwa zifuna utyalo-mali olukhulu kwaye zifuna uhlobo oluthile lokucocwa kwesithuba ukususa uthuthu olushiyekileyo. Amalungu kufuneka amelane namaqondo obushushu angama-800°F (427°C). Ezinye iikhemistri zokugquma aziyilungelanga le ndlela yokuhluba. Qhagamshelana nomenzi wezixhobo kunye nee-arhente ezilawulayo zendawo. Kufuneka kwakhona kuqatshelwe ukuba ukuhluthwa okuphindaphindiweyo kwesixhobo kunokufuna uhlobo oluthile lwe-alloy ukunqanda ukuphuka okanye ukuguqulwa.

Ukuqhuma kwe-Shot

Ukudubula, okanye ukugqabhuka, kungasetyenziselwa ukuhluba iindawo okanye ii-hangers xa ezinye iindlela zithintelwe. Le nkqubo icotha kakhulu ngenxa yokuqina komgubo ocoliweyo owenziweyo. Ububi bale nkqubo kukuba ikhukulisa (iyancipha) isixhobo kwaye iveze indawo engaphezulu yomphezulu, ethi ibe nzima ukuyikhulula xa iphinde yagqunywa.

I-Cryogenic

I-Cryogenic stripping imbrittles ifilimu nge-nitrogen engamanzi, emva koko isebenzisa i-nonabrasive shot blast ukususa ngokulula i-coating. Le yindlela ekhawulezayo, engangcolisi, kodwa ifuna izixhobo ezikhethekileyo. Amalungu kufuneka anyamezele -100 ° F (-37 ° C) athathelwe ingqalelo kwisixhobo.

GEZARAL

Kufuneka kuqwalaselwe ukuba ingaba amalungu angakwazi na ukumelana nayo nayiphi na kwezi ndlela zichaziweyo. Abathengisi bemichiza kunye nezixhobo banokutshisa, kwaye uhlobo oluthile lwe-alloy lunokufuneka luncedise ekuzimiseleni. Xa kuziwa kwisixhobo, ukuyila okufanelekileyo kunokunciphisa inani lokucoca okuyimfuneko. I-part hook engabizi kakhulu inokubiza kakhulu ukuba kufuneka itshintshwe rhoqo.
