Inenge 5 zambere zujuje ubuziranenge Co imizingo ya aluminiyumu (nuburyo bwo kubyirinda)

Mu kwihuta kwihuta-gukora no gukora mubwubatsi, kwakira ibishishwa bya aluminiyumu bifite inenge birashobora gutuma umusaruro utinda cyane, ibikoresho byakuweho, hamwe namakimbirane asaba amafaranga menshi. Haba gukora ibipapuro byerekana imashini, paneli ya sandwich, cyangwa amabati ya aluminiyumu, kwemeza ko ibigega bya zeru bifite inenge ari ngombwa.

Gusobanukirwa nintandaro yamakosa asanzwe atuma abashinzwe gutanga amasoko naba injeniyeri beza bagenzura abaguzi neza kandi bagashyiraho ubuhanga bukomeye. Hano haribintu bitanu byambere bifite ubuziranenge biboneka muri coil ya aluminiyumu hamwe ningamba zifatika zo kubikuraho.

1. Ibara ritandukanye (Delta E Off-Spec)

Ibara ridahuye hagati yingingo zitandukanye - cyangwa no hejuru yumutwe, hagati, numurizo wigiceri kimwe - nimwe mubitera kwangwa mubucuruzi.

Impamvu Imizi: Imihindagurikire yo gukiza ubushyuhe bwitanura (PMT), irangi ridahuye, cyangwa irangi ridakwiye mugihe gikomeza umurongo.

Ingamba zo gukumira: Gutegeka ibizamini bya spekitifotometero hamwe no kwihanganira byimazeyo (urugero, ΔE <0.5 kumabara akomeye, ΔE <1.0 kubirangiza byuma). Menya neza ko uwabikoze agumana irangi rimwe rivanze kubikorwa byumushinga munini.

2. Micro-Cracking na Flaking mugihe cyo gushiraho (Kunanirwa T-Bend)

Iyo ibishishwa bya aluminiyumu byanyuze mu muvuduko wihuse-bipfa gupfa, igipfundikizo gishobora guturika mikoro cyangwa kigahagarara kuri radiyo igoramye.

Impamvu Imizi: Filime irangi yakize cyane, uburebure bwa firime yumye (DFT), cyangwa guhitamo sisitemu yo gutwikira idahagije (urugero, bisanzwe PE aho kuba PU / PA yihariye cyangwa polyester yoroheje).

Ingamba zo gukumira: Kugaragaza imikorere ya 0T - 1T yunamye ukurikije ASTM D4145. Kumwirondoro uhindagurika cyane nka shitingi, koresha ibintu byoroshye bya Polyurethane-Polyamide (PU / PA) hanyuma urebe ibipimo bya PMT mbere yumusaruro rusange.

3. Pinholes, Blisters, na Peel Peel

Ubuso bwimiterere yubuso buhungabanya ubwiza bwamaso kandi bugashyira munsi ya aluminium substrate munsi yubushuhe nibintu byangiza.

Impamvu Imizi: Guhumuka byihuse (guhumeka neza) biterwa nubushyuhe bukabije mukarere gakiza, amavuta / ivumbi ryanduye kumurongo mbisi mbere ya chromating, cyangwa ibintu bitaringaniza muburyo bwo gusiga irangi.

Ingamba zo Kwirinda: Shyira mubikorwa ibyiciro byinshi mbere yo kuvura (gusukura, gutesha agaciro, no guhinduranya ibintu) hamwe no kugenzura umurongo wa interineti wikora. Menya neza ko umurongo utwikiriye ukoresha amashyiga menshi ya convection kugirango uhuze flash-off.

4. Gutwika Ipfunyika hamwe na MEK Rub Kurwanya Kurwanya

Gusiba gusiba bibaho mugihe firime irangi itakaje kwizirika kuri primer cyangwa aluminiyumu fatizo, bikaviramo gucika intege mukibazo cya mashini.

Impamvu Imizi: Kudakira neza (ubushyuhe bwicyuma budahagije), chromate yangiritse / urwego rudasanzwe rwa chromate, cyangwa ibisigazwa byamavuta bisigaye kuri aluminiyumu yambaye ubusa (urugero, 3004, 3105).

Ingamba zo Kwirinda: Kora ibizamini bisanzwe bya MEK solvent ( ASTM D5402) kuri buri gicapo cyerekana umusaruro (> 100 rubs ebyiri kuri PVDF / PUPA). Kugenzura mbere yubuvuzi bwa firime mbere yo gusaba primer.

5. Edge Burr Ibyangiritse na Coil Edge Telescoping

Ubusembwa bwumubiri bukunze kugaragara mugihe cyo gutobora neza no gusubiza inyuma aho gusiga irangi.

Impamvu Imizi: Yambaye ibyuma byacagaguritse, gukuramo ibyuma bitari byo, cyangwa guhagarika umutima ku buryo budasubirwaho mugihe cyo gusubiza hamwe, biganisha ku musego wo kumenagura uduce twa firime ikingira no gushushanya ibipfunyika byegeranye.

Ingamba zo gukumira: Shiraho uburyo bworoshye bwo kwihanganira ubugari (± 0.2 mm) hanyuma ushyire mubikorwa gahunda yo gufata ibyuma. Koresha impagarara zikora kandi ziyobora kuruhande mugihe cyo kwisubiraho kugirango umenye neza, nta burr.

Kugenzura neza no gukumira Matrix

Urashaka Zeru-Yuzuye yabanje gusigwa irangi imizingo ya aluminiyumu ?

Dushimangira 100% kumurongo wo kureba amashusho, kwemeza MEK rub, hamwe no kugenzura ubuziranenge bwa T-bend kuri buri cyiciro cyohereza ibicuruzwa hanze. Menyesha itsinda ryacu ryubuhanga kugirango usabe raporo yubugenzuzi bwuruganda cyangwa ingero zifatika.
