Ipleyiti yentsimbi eGqwethiweyo ekumgangatho ophezulu
Ipleyiti yentsimbi eyakhiwe yahlulwe yaba yipleyiti eqhelekileyo ye-electrolytic kunye nepleyiti yeminwe exhathisa i-electrolytic.Ipleyiti enganyangekiyo yeminwe yongeza unyango oluxhathisa umnwe ngokwesiseko sepleyiti eqhelekileyo ye-electrolytic, enokumelana nokubila.Isetyenziswa ngokubanzi kwiindawo ngaphandle konyango, kwaye uphawu luyi-secc-n.Ipleyiti eqhelekileyo ye-electrolytic inokohlulwa ibe yipleyiti ye-phosphating kunye ne-passivation plate.I-Phosphating isetyenziswa ngokuqhelekileyo.Ibhrendi yi-secc-p, eyaziwa ngokuba yi-P material.Ipleyiti yePassivation inokwahlulwa ibe yi-oyile kwaye ayifakwanga.Iimfuno zomgangatho wephepha eligqwesileyo legalvanized zibandakanya ukucaciswa kunye nobukhulu, umphezulu, ubungakanani begalvanized, ukwakheka kweekhemikhali, ukumila kweshiti, ukusebenza komatshini kunye nokupakishwa.
Yahlulahlulwe yaba ziindidi ezimbini: ishidi elifakwe igalvanized lisikwe kubude obusisigxina kunye nokupakishwa kwephepha eliqengqelekayo.Ukupakishwa kwamaphepha entsimbi ngokubanzi, afakwe ngephepha elingangenwa bumanzi, ebotshelelwe ngaphandle esinqeni sentsimbi, ebotshelelwe ngokuqinileyo, ukuze kuthintelwe iipleyiti zangaphakathi zamagalvanized ekubeni zikhuhlane.
Imilinganiselo yemveliso efanelekileyo (efana nale ilandelayo kwaye) dwelisa imilinganiselo ecetyiswayo, ubukhulu, ubude, ububanzi kunye neziphene ezivumelekileyo zeshiti legalvanized.Ukongezelela, ububanzi kunye nobude bebhodi kunye nobubanzi bomqulu bunokumiselwa ngokwesicelo somsebenzisi.
Imeko ngokubanzi: ngenxa yeendlela ezahlukeneyo zonyango kwinkqubo yokwaleka, imeko jikelele yephepha elenziwe ngamazinki yahlukile, njengemeko eqhelekileyo yentyatyambo ye-zinc eqhelekileyo, intyatyambo ye-zinc entle, intyatyambo ye-zinc ecaba, intyatyambo engeyiyo i-zinc kunye nonyango lwe-phosphating.I-galvanized sheet kunye ne-galvanized coil enqunywe ubude obusisigxina ayiyi kuba neziphene ezichaphazela ukusetyenziswa (njengoko kuboniswe ngezantsi), kodwa i-coil ivumelekile ukuba ibe neengxenye ze-welding kunye nokunye.
Ixabiso lesikali sobungakanani begalvanized: ubungakanani begalvanized yindlela eyamkelwa ngokubanzi neluncedo yokubonisa ubukhulu be-zinc layer ye-galvanized sheet.Kukho iindidi ezimbini: ubungakanani obufanayo bokugalela kumacala omabini (okt ukugaywa kwegalvanizing ubukhulu obulinganayo) kunye nenani elahlukileyo lokugalela kumacala omabini (okt ukugaywa kwegalvanizing ubukhulu).Iyunithi yobungakanani begalvanizing yi g/m.
(1) Uvavanyo lwe-tensile: Ukuthetha ngokubanzi, ukuba nje iphepha elifakwe igalvanized loyilo, umzobo kunye nomzobo onzulu uneemfuno zomsebenzi oqinileyo.
(2) Ukulinga ukugoba: yinto ebalulekileyo ukulinganisa umsebenzi wenkqubo yepleyiti encinci.Nangona kunjalo, iimfuno zeentlobo ezahlukeneyo zamaphepha ahlukeneyo ahlukeneyo kumazwe ahlukeneyo.Ngokuqhelekileyo kufunwa ukuba emva kokuba i-galvanized sheet igotywe kwi-180, akuyi kubakho umaleko we-zinc oshiywe kumphezulu wangaphandle, kwaye akuyi kubakho ukuqhekeka kunye nokuqhekeka kwisiseko seplate.
Iimfuno zokwakheka kweekhemikhali ze-galvanized substrate ziyahluka kumazwe ahlukeneyo.Ukuba iJapan ayiceli, iUnited States iyakwenza.Ngokuqhelekileyo, ukuhlolwa kwemveliso akuqhutywa.
Kukho iinjongo ezimbini zokulinganisa ubume bepleyiti, ezizezi, ukugoba nokugoba irhengqa.Ukuthe tyaba kwepleyiti kunye nelona xabiso likhulu elivumelekileyo lokugoba irhengqa liyachazwa.Idiphu eshushu iipleyiti zentsimbi eziveliswe ngabavelisi baseTshayina zisetyenziswa ikakhulu kwizinto zokwakha, ishishini elikhanyayo, ezolimo, ezothutho kunye namanye amashishini.Ngenxa yonyino lwemeko ekhoyo yezixhobo zokugalela i- hot-dip, inkqubo yeteknoloji kunye nokusebenza kwepleyiti ekrwada, zimbalwa iipleyiti ezifakwe igalvanized ezifumanekayo zokwenziwa kwemoto.
I-galvanizing inokuthintela ngokufanelekileyo ukubola kwentsimbi kunye nokwandisa ubomi benkonzo.Ishiti lentsimbi elenziwe ngesinyithi (0.4 ~ 1.2mm ubukhulu) likwabizwa ngokuba yi sheet sheet, eyaziwa ngokuba yintsimbi emhlophe.Ishiti lensimbi eliphekiweyo lisetyenziswa ngokubanzi kulwakhiwo, izithuthi, izixhobo zendlu, iimfuno zemihla ngemihla kunye namanye amashishini.
