Unyango lwePickling Phosphating

Yintoni i-picling phosphating
Yinkqubo yonyango lwesinyithi, i-pickling kukusetyenziswa koxinzelelo lwe-asidi ukucoca isinyithi ukususa umhlwa ongaphezulu.I-Phosphating ukucwina isinyithi esihlanjwe nge-asidi kunye nesisombululo se-phosphating ukwenza ifilimu ye-oxide phezu komhlaba, enokuthintela ukugqwala kunye nokuphucula ukunamathela kwepeyinti ukulungiselela isinyathelo esilandelayo.

Ukunqunqa ukususa umhlwa kunye namaxolo yeyona ndlela isetyenziswa kakhulu kwindawo yoshishino.Injongo yokususa i-rust kunye nokususwa kwesikhumba kufezekiswa ngokuchithwa kwe-mechanical ye-hydrogen eveliswa ngokuchithwa kwe-asidi ye-oxide kunye ne-corrosion.Ezona ziqhelekileyo zisetyenziselwa ukukha i-hydrochloric acid, i-sulfuric acid kunye ne-phosphoric acid.Iasidi ye-nitric ayifane isetyenziswe kuba ivelisa igesi yenitrogen dioxide enetyhefu ngexesha lokuchola.I-Hydrochloric acid pickling ilungele ukusetyenziswa kumaqondo aphantsi, akufanele idlule i-45 ℃, ukusetyenziswa koxinaniso lwe-10% ukuya kwi-45%, kufuneka idibanise isixa esifanelekileyo se-acid inhibitor efanelekileyo.I-asidi ye-Sulphuric kwisantya esisezantsi sokuchola isantya sicotha kakhulu, kufuneka sisetyenziswe kwiqondo lobushushu eliphakathi, iqondo lobushushu le-50 ~ 80℃, ukusetyenziswa koxinzelelo lwe-10% ~ 25%.I-advanteji ye-phosphoric acid pickling kukuba ayiyi kuvelisa iintsalela ezonakalisayo (ngaphezulu okanye ngaphantsi kuya kubakho i-Cl-, i-SO42- intsalela emva kwe-hydrochloric acid kunye ne-sulfuric acid pickling), ekhuseleke kakhulu, kodwa ukungahambi kakuhle kwe-asidi ye-phosphoric kukuba ixabiso liphezulu, isantya sokuchola sicotha, ukusetyenziswa ngokubanzi kwe-10% ukuya kwi-40%, kwaye ubushushu bonyango bunokuba lobushushu obuqhelekileyo ukuya kuma-80℃.Kwinkqubo yokukhetha, ukusetyenziswa kwe-acids edibeneyo kuyindlela esebenzayo kakhulu, njenge-hydrochloric-sulfuric acid exutywe ne-acid, i-phospho-citric acid exutywe.Ubungakanani obufanelekileyo be-corrosion inhibitor kufuneka bongezwe kwi-pickling, ukususwa komhlwa kunye nesisombululo setanki yokususa i-oxidation.Kukho iintlobo ezininzi ze-corrosion inhibitors, kwaye ukhetho lulula, kwaye indima yalo kukuthintela ukubola kwesinyithi kunye nokukhusela "i-hydrogen embrittlement".Nangona kunjalo, xa ukhetha "i-hydrogen embrittleness" i-workpieces ebuthathaka, ukhetho lwe-corrosion inhibitors kufuneka lulumke ngakumbi, kuba ezinye ii-corrosion inhibitors zithintela ukuphendula kweeathom ezimbini ze-hydrogen kwiiathom ze-hydrogen, ezizezi: 2[H]→H2↑, ukuze ugxininise. yeeathom ze-hydrogen kumphezulu wesinyithi yanda, ukunyusa ukuthambekela kwe-"hydrogen embrittleness".Ngoko ke, kuyimfuneko ukubonisana nencwadana yedatha ye-corrosion okanye wenze uvavanyo lwe "hydrogen embrittlements" ukuze ugweme ukusetyenziswa kwe-corrosion inhibitors eyingozi.

Ukuphumelela kweteknoloji yokucoca imboni - ukucocwa kwe-laser eluhlaza
Itekhnoloji ebizwa ngokuba yi-laser yokucoca itekhnoloji ibhekisa kusetyenziso lomqa we-laser wamandla aphezulu ukuntywila umphezulu womsebenzi, ukuze umphezulu wokungcola, umhlwa okanye ugqume umphunga okhawulezileyo okanye ukuhluba, isantya esiphezulu kunye nokususwa okusebenzayo komphezulu wento. i-attachment okanye i-surface coating, ukwenzela ukuba kuphunyezwe inkqubo ecocekileyo.Ubuchwephesha obutsha obusekwe kwisiphumo sokusebenzisana kwe-laser kunye ne-substance, kwaye ineenzuzo ezicacileyo xa kuthelekiswa neendlela zokucoca zemveli ezinje ngokucoca ngoomatshini, ukucocwa kwekhemikhali ye-corrosion, ukucoca okuqinileyo okuqinileyo, ukucocwa kwe-ultrasonic frequency.Isebenza kakuhle, ngokukhawuleza, ixabiso eliphantsi, umthwalo omncinci we-thermal kunye nomthwalo womatshini kwi-substrate, kwaye ungonakalisi ukucoca;Inkunkuma inokuphinda isetyenziswe, akukho zingcoliseko zokusingqongileyo ezikhuselekileyo nezithembekileyo, zingonakalisi impilo yomsebenzisi unokususa iintlobo ezahlukeneyo zobunzima, amacandelo ahlukeneyo omgangatho wokucoca inkqubo yokucoca kulula ukufezekisa ulawulo oluzenzekelayo, ukucocwa kokulawula kude kunye nokunye.

Itekhnoloji yokucoca i-laser eluhlaza kunye ne-pollution-free isombulula ngokupheleleyo ukugxekwa kongcoliseko lokusingqongileyo kwi-pickling phosphating technology treatment.Itekhnoloji yokhuseleko lokusingqongileyo kunye netekhnoloji yokucoca eluhlaza - "ukucocwa kwe-laser" kwabakho kwaye kwavuka kunye nomsinga.Uphando lwayo kunye nophuhliso kunye nokusetyenziswa kwayo kukhokelela utshintsho olutsha lwemodeli yokucoca ishishini kunye nokuzisa inkangeleko entsha kushishino lwehlabathi lonyango.
