Sezvo iyo yekuputira inopedzwa nezvinoita corrosive, pendi inorasikirwa nekunamatira kwayo uye inoputika kana kuputika kubva pamusoro. Kukobvura kwesimbi kupfekedzwa, kunonokesa kukurumidza kwepasi uye kunonokesa kukurumidza kwekucheka-cheka.
Kana iri galvanizing, kukosha kwe zinc coating ukobvu, kunyanya pamatenga, ndicho chimwe chezvikonzero nei vazhinji vanogadzira mapeji ezvigadzirwa zvemarata vachikurudzira ASTM A653 yakajairwa mataurirwo ekupisa-dip galvanized (galvanized) kana zinc-iron alloy steel sheet. dipping process (galvanized annealed), uremu hwekunamira (kureva uremu) zita reG90 (kureva 0.90 oz/sqft) Z275 (kureva 275 g/m2) yakakodzera kune akawanda akapendirwa mapendi emarata ekushandisa. Kune pre-coatings ye55% AlZn, dambudziko rekukora rinowedzera kuoma kune akati wandei zvikonzero. ASTM A792/A792M, Standard Specification yeSimbi Plate, 55% Kupisa Dip Aluminium-Zinc Alloy Coating Weight (kureva Misa) Dhizaini AZ50 (AZM150) ndiyo inowanzorongedzerwa jaketi sezvo yakaratidza kuti yakakodzera kushanda kwenguva refu.
Chinhu chimwe chekuchengeta mupfungwa ndechekuti roll coating operations kazhinji haigone kushandisa simbi-yakavharwa shiti iro rakapfuudzwa nemakemikari ane chromium. Makemikari aya anogona kusvibisa ma cleaners uye pre-treatment solutions for painted mitsara, saka mabhodhi asina-passivated anonyanya kushandiswa. 3
Nekuda kwekuoma kwayo uye brittle hunhu, Galvanized Treatment (GA) haishandiswe mukugadzira pre-painted simbi mapepa. Chisungo chiri pakati pepende neiyi zinc-iron alloy coating chakasimba kupfuura chisungo chiri pakati pekupotera nesimbi. Panguva yekuumba kana kukanganisa, GA inotsemuka uye kudonhedza pasi pepende, zvichiita kuti zvidimbu zvese zvibviswe.
Paint System Mafungiro Zviripachena, chimwe chezvakakosha zvakanyanya mukuona kuita kwakanaka ipende inoshandiswa pabasa racho. Semuenzaniso, munzvimbo dzinogamuchira chiedza chezuva chakawanda uye kuratidzwa kwakanyanya kweUV, zvakakosha kuti usarudze kupera-kusagadzikana kwekupedzisira, nepo munzvimbo dzine hunyoro hwakanyanya, kusati kwaitwa uye kupedzisa kwakagadzirirwa kudzivirira unyoro ingress. (Nyaya dzine chekuita nekushandisa-chaiyo coating system dzakawanda uye dzakaoma uye dziri pamusoro pechikamu chechinyorwa ichi.)
Kupokana kwekuora kwesimbi yakapendwa inokanganiswa zvakanyanya nekemikari uye kugadzikana kwemuviri kweiyo interface pakati pezinc pamusoro uye organic coating. Kusvika nguva pfupi yadarika, zinc plating yakashandisa yakasanganiswa oxide kemikari kurapwa kuti ipe interfacial bonding. Zvishandiso izvi zviri kuramba zvichitsiviwa nekukora uye kuonda kusingaite zinc phosphate coatings izvo zvinogara zvisingaite kukora pasi pefirimu. Zinc phosphate inonyanya kushanda munzvimbo dzegungwa uye mumamiriro ekunyorova kwenguva refu.
ASTM A755/A755M, gwaro rinopa kutarisisa kwezvipfeko zviripo kune zvigadzirwa zvesimbi-yakavharidzirwa simbi, inonzi "Steel Sheet, Hot Dip Coated Metal" uye pre-yakaputirwa necoil coil yezvigadzirwa zvekuvaka zvinoiswa pasi pesimba re mamiriro ekunze.
Maitiro ekufunga kwekuputira pre-coated rolls Imwe yakakosha shanduko inokanganisa hupenyu hwechigadzirwa chakafanovharwa in situ kugadzirwa kwepepa rakavharwa. Iyo yekupfekedza maitiro e-pre-coated rolls inogona kukanganisa zvakanyanya kuita. Semuenzaniso, kunamatira kwakanaka kwependi kwakakosha kudzivirira kusvuuka kana kuputika kwepende mumunda. Kunamatira kwakanaka kunoda yakanyatsodzorwa roll coating kubata maitiro. Nzira yekupenda mipumburu inokanganisa hupenyu hwebasa mumunda. Nyaya dzakafukidzwa:
Vagadziri vanogadzira ma roll coating vanogadzira pre-pendi mapepa ezvivakwa vane masisitimu emhando yakanyatsogadziriswa anovimbisa kuti nyaya idzi dzakadzorwa nemazvo. 4
Profileing uye mapanera dhizaini maficha Kukosha kwepanera dhizaini, kunyanya inopeta radius padivi pembabvu yekuumba, ndiyo imwe nyaya yakakosha. Sezvambotaurwa, zinc corrosion inoitika apo firimu repende rakakuvadzwa. Kana iyo mapaneru akagadzirwa nediki bend radius, pachagara paine kuputika mupende. Izvi zvinoputika zvinowanzova zviduku uye zvinowanzonzi "microcracks". Nekudaro, iyo simbi yekuputira inofumurwa uye kune mukana wekuwedzera kwehuwandu hwekuora pamwe nekukotama radius yepaneru yakatenderedzwa.
Iko mukana we microcracks mumabhendi hazvireve kuti zvikamu zvakadzika hazvigoneke - vagadziri vanofanirwa kupa iyo yakakura inogoneka bend radius kuti igare zvikamu izvi.
Pamusoro pekukosha kwepaneru uye roll yekugadzira muchina dhizaini, kushanda kweiyo roll yekugadzira muchina kunokanganisawo kubudirira mumunda. Semuenzaniso, nzvimbo yeroller set inokanganisa chaiyo bend radius. Kana kurongeka kukasaitwa nemazvo, mabhendeti anogona kugadzira akapinza kinks paprofile bend pachinzvimbo ches smooth smooth bend radii. Izvi "zvakaoma" zvinokotama zvinogona kutungamirira kune zvakanyanya kuoma microcracks. Izvo zvakakoshawo kuti mating rollers arege kukwenya pendi, nekuti izvi zvinoderedza kugona kwependi kuenderana nekushanda kwekukotama. Cushioning nderimwe dambudziko rakabatana rinoda kuzivikanwa panguva yekunyorwa. Iyo yakajairika nzira yekubvumidza springback ndeye "kink" pani. Izvi zvinodikanwa, asi kukotama kwakanyanya panguva yekushanda kweprofiling kunokonzeresa mamwe ma microcracks. Saizvozvo, kuvaka mapaneru ekugadzira ekugadzirisa maitiro akagadzirirwa kugadzirisa nyaya idzi.
Mamiriro anozivikanwa se "magaba emafuta" kana "homwe" dzimwe nguva anoitika pakukungurusa pre-painted simbi mapaneru. Mapanel profiles ane madziro akafara kana zvikamu zvakati sandara (eg maprofiles ekuvaka) anonyanya kutapukirwa. Mamiriro ezvinhu aya anogadzira chimiro chisingagamuchirwi chewavy paunenge uchiisa mapaneru pamatenga nemadziro. Magaba emafuta anogona kukonzerwa nezvikonzero zvakasiyana-siyana, zvinosanganisira kusadzikama kwebepa rinouya, roller press mashandiro uye nzira dzekukwira, uye zvinogona zvakare kuve mhedzisiro yekusungirirwa kwepepa panguva yekugadzira sezvo kumanikidza kudzvanywa kunogadzirwa munzira yekureba. sheet. panel. 5 Iyi elastic buckling inoitika nekuti simbi ine yakaderera kana zero goho simba elongation (YPE), iyo stick-slip deformation inoitika kana simbi yakatambanudzwa.
Panguva yekukungurutswa, shizha rinoedza kutetepa munzira yekukora uye kuderera munzira yekureba munharaunda yewebhu. Mune yakaderera YPE simbi, iyo isina kuchinjika nzvimbo iri padyo nebend inodzivirirwa kubva pakureba shrinkage uye iri mukumanikidza. Kana iyo compressive stress ichidarika iyo inodzikamisa elastic buckling stress, masaisai ehomwe anoitika mudunhu remadziro.
