Ukulungiswa kwezingxenye kanye ne-hanger stripping embotsheni yempushana

Izindlela zokulungisa ingxenye ngemuva i-powder coating zingahlukaniswa izigaba ezimbili: touch-up futhi recoat.
Ukulungiswa kokuthinta kufanelekile uma indawo encane yengxenye eboshiwe ingamboziwe futhi ayikwazi ukuhlangabezana nezincazelo zokuqeda. Uma izimpawu zokuphanyeka zingamukelekile, ukuthinta-up kuyadingeka. I-Touch-up nayo ingase isetshenziselwe ukulungisa umonakalo omncane osuka ekuphathweni, ekwenzeni imishini, noma ekushiseleni ngesikhathi sokuhlanganisa.

I-recoat iyadingeka lapho ingxenye yenqatshwa ngenxa yokulimala kwendawo enkulu noma lapho ukuthinta kungamukeleki. Kuleli qophelo, kunezinhlobonhlobo zezinketho okufanele zicatshangelwe ngokucophelela. Ngokuvamile ingxenye enqatshiwe ingaphinde ihlanganiswe nejazi lesibili. Enye inketho ukuhlubula nokupenda kabusha ingxenye. Ukukhumula kungase futhi kuhlanze ama-hangers ukuze kunikeze indawo enhle
isifutho se-electrostatic.

THINTA

Upende othintwayo owuketshezi usetshenziswa ngebhulashi elincane, isifutho se-aerosol, noma isibhamu esingenamoya. Upende womiswe ngomoya. Inqubo yokomisa ingasheshiswa ngokubhaka okuphansi kwezinga lokushisa. Ipeyinti yokuthinta isetshenziswa ngemuva kokuthi i-powder coating selapheke ngokugcwele kuhhavini wokubhaka. Izimpawu zokuphanyeka, izindawo ezikhanyayo emakhoneni nasezintanjeni, umonakalo ovela ekushiseleni noma ekuhlanganiseni, nokunye ukukhubazeka okuncane kungathinteka. Generally, a umbala-Kusetshenziswa koqweqwe lwawo lwe-acrylic noma i-lacquer. Upende othintwayo awukwazi ukusetshenziswa uma ungeke uhlangabezane nezicaciso zokusebenza ezidingekayo phakathi nokuphila okulindelekile kwaleyo ngxenye.
Ukuthinta akufanele kusetshenziselwe ukulungisa isiphetho esinephutha ngaphandle kwalapho umkhiqizo ophumayo uhlangabezana nezindinganiso zokuhlola.

RECOAT

Ukufaka ijazi lesibili lempushana kuyindlela evamile yokulungisa nokubuyisela izingxenye ezinqatshiwe. Kodwa-ke, inkinga kufanele ihlaziywe ngokucophelela futhi umthombo ulungiswe ngaphambi kokuhlanganisa kabusha. Ungaphindi uma ukwenqatshwa kubangelwe iphutha lokwenziwa, i-substrate yekhwalithi engeyinhle, ukuhlanzeka okungeyikho noma ukulungiswa kwangaphambili, noma uma ukujiya kwamajazi amabili kuhlangene kuzobe kungabekezeleleki. Futhi, uma ingxenye yenqatshwa ngenxa yokungasebenzi kahle, idinga nje ukubhakwa kabusha ngeshejuli edingekayo.

Ijazi lesibili lisebenza kahle ukumboza izindawo ezikhanyayo, ukonakala okungaphezulu kokungcola nokungcoliswa, amachashaza amaholoholo avela ekwakhiweni kwefilimu esindayo noma ukuphalaza kwesibhamu, kanye nokushintsha kombala ekushiseni okukhulu. Izindawo ezimahhadlahhadla kanye nama-protrusions kufanele zigaywe ngesihlabathi bushelelezi ngaphambi kokubuyisela.

Izingxenye ezihlolwe ku-inthanethi zingashiywa ku-conveyor ukuze zithole ijazi lesibili. Lezi zingxenye zingadlula ezigabeni zokwelashwa ngezingxenye ezingavuthiwe. Uma izingxenye eziboshwe kabusha zibonisa amachashaza amanzi noma amabala, ukulungiswa kungenziwa esigabeni sokugcina sokuhlanza.

Abahlinzeki bamakhemikhali banganikeza izincomo. Lapho izingxenye ze-recoat zilenga ndawonye, ​​ukuhlanza nokwelashwa kwangaphambili akudingekile. Kodwa-ke, uma izingxenye ezinqatshiwe zigcinwe ukuze ziqongelele inombolo engokoqobo, kufanele zihlolwe ukungcola nokungcoliswa.

Ijazi Yonke Ingxenye

Uma usebenzisa ijazi lesibili, ubukhulu obujwayelekile be-mil kufanele busetshenziswe kuyo yonke ingxenye. Iphutha elivamile ukugqoka kuphela indawo enesici. Lokhu kushiya indawo engamatshe lapho kunongqimba oluncane kakhulu lwe-spray engxenyeni esele. Uhlelo olufanayo lokwelapha olunconyiwe lusetshenziselwa ijazi lesibili.

Ukunamathela kwe-Intercoat kungabhekwa ngemva kokwembozwa kabusha kumasampuli akhethiwe ngokusebenzisa ukuhlolwa kwe-cross hatch noma ngokumane ukunwaya indawo engaphezulu ukuze kubonakale ukuthi ijazi lesibili liyaxebuka yini ukusuka kwelokuqala. Ezinye izimbobo eziyimpushana zingase zidinge ukuthi zifakwe isihlabathi esincane ukuze zinikeze ihange elihle lejazi lesibili.

BUYISA

Uma ingxenye ingasebenzi kahle ngesikhathi sejazi lokuqala, ingalungiswa ngokuyibuyisela kuhhavini wokubhaka ukuze uthole uhlelo olujwayelekile lokwelapha ngesikhathi esibekiwe kanye nezinga lokushisa. Izakhiwo zizobuyiswa lapho ingxenye yelashwe kahle, ngaphandle kokunye okuhlukile, okufana nezimbotshana ezithile ezilawulwa ngamakhemikhali ezicwebezelayo. Ukwelapha ngokwengxenye kuyophumela ekucwebezeleni okuphezulu, okungehli kufinyelele ezingeni elifanayo phakathi nokwelashwa kokugcina obekungatholakala ngokwelashwa okwanele kokuqala.

UKUHLULA

Ukukhumula ngokuvamile kuyindlela yokugcina yokulungisa ingxenye njengoba ukukhumula umkhiqizo owenqatshiwe kungangeza kakhulu ezindlekweni zokukhiqiza futhi kuphazamise ukugeleza komugqa wokukhiqiza. Ukukhumula izingxenye ezimboziwe kuba kudingekile, noma kunjalo, lapho ukwenqatshwa kubangelwa ukungaphathwa kahle noma lapho ukuthinta noma amajazi amabili kungamukeleki.
Ngakolunye uhlangothi, ukukhumula kudlala indima ebalulekile ekusebenzeni komugqa we-powder coating ngokunikeza ama-hangers ahlanzekile endaweni enhle kagesi. Ama-Hangers kufanele asuswe ngezikhathi ezithile. Izindlela zokukhumula kuxoxwa ngazo ezigabeni ezilandelayo. (Qaphela: Kukhona umehluko wemibono yokuthi ukukhumula amakhemikhali kuyindlela ekhethwayo.)

Ama-stripper amakhemikhali ayatholakala ukuze asetshenziswe kushisa (izinga lokushisa eliphakanyisiwe) noma amakhaza (ama-ambient) ethangini lokucwilisa. Kukhona i-asidi, i-alkaline, nezinhlobo zikasawoti oncibilikisiwe, nokukhethwa kuye ngohlobo lwezingxenye nama-hangers kanye nokunameka okufanele kukhishwe.

Inzuzo enkulu yama-stripper amakhemikhali ukutshalwa kwezimali okuphansi kokuqala kwemishini. Okubi kuhlanganisa izingozi zokuphepha zokuphatha amakhemikhali, izindleko eziphezulu zokushintshwa kwamakhemikhali nokulahlwa kwawo, namakhemikhali agcwele upende. Ezinye izingxenye, njengama-alloys e-aluminium, zingase zingakwazi ukumelana nokugqwala kwamakhemikhali.

Shisa

Ukushisa, noma i-pyrolysis, amahhavini okukhumula asebenzisa amazinga okushisa aphezulu ukushisa okunamathelayo. Kungaba uhlobo lwe-batch noma ohhavini abaku-inthanethi abasebenza cishe ku-800°F (427″C), abakhipha umoya wokulawula ukungcola osebenza emazingeni okushisa acishe abe ngu-1200-1300°F (649-704°C). Ohhavini abashile baqeda ukungcola kanye nezinkinga zokulahla. Asebenza kahle uma kuqhathaniswa, kodwa adinga ukutshalwa kwezimali okukhulu futhi adinga uhlobo oluthile lokuhlanzwa kweposi ukususa umlotha osele. Izingxenye kumele zimelane nezinga lokushisa elingu-800°F (427°C). Amanye amakhemikhali okugcoba awayilungele le ndlela yokukhumula. Xhumana nomkhiqizi wezisetshenziswa kanye nama-ejensi alawulayo wendawo. Kufanele futhi kuqashelwe ukuthi ukuhlubula okuphindaphindiwe kwamathuluzi kungase kudinge uhlobo oluthile lwe-alloy ukuvimbela ukuphuka noma ukonakala.

Ukuqhuma kwe-Shot

Ukuqhunyiswa kwesibhamu, noma ukuhushulwa, kungasetshenziswa ukukhumula izingxenye noma iziphanyeko lapho ezinye izindlela zingavunyelwe. Le nqubo ihamba kancane ngenxa yokuqina kwe-powder coating. Ububi bale nqubo ukuthi iguguleka (yenza ibe mncane) into esetshenziswayo futhi iveze indawo engaphezulu, okuba nzima ukuyikhumula uma ihuqwe kabusha.

I-Cryogenic

Ukukhumula i-Cryogenic kuhlobisa ifilimu nge-nitrogen ewuketshezi, bese kusebenzisa isibhamu esiqhumayo ukuze kususe kalula ukunamathela. Lena indlela esheshayo, engangcolisi, kodwa idinga imishini ekhethekile. Izingxenye kufanele zibekezelele -100°F (-37°C) zicatshangelwe ukuze zisetshenziswe.

GeneRAL

Kumelwe kucatshangelwe ukuthi izingxenye zingakwazi yini ukumelana nanoma yiziphi izindlela ezichaziwe. Abahlinzeki bamakhemikhali nemishini bangashisa, futhi uhlobo oluthile lwengxubevange kungase kudingeke lusize kulokho kunqunywa. Uma kuziwa ekusetshenzisweni kwamathuluzi, ukuklama okufanele kunganciphisa inani lokuhlanza okudingekayo. I-part hook engabizi ingabiza kakhulu uma kufanele ishintshwe njalo.
