Ukunyuka kwamagunya amakhulu ehlabathi onke aqala ekwakhiweni kweenqanawa aze adlule elwandle.Njengophawu olubalulekileyo lwenqanaba lemveliso yelizwe,ishishini lokwakha iinqanawa, njenge "isithsaba samashishini abanzi", inomgangatho ophezulu wokwandiswa kwamashishini kunye nokuqhubela phambili kwezoshishino.Ukusukela kwisiqingatha sokuqala salo nyaka, ukunqongophala komthamo wokuthuthwa kwenqanawa kwihlabathi kukhokelele ekunyukeni kwamaxabiso enqanawa, kwaye ukukhula kwemfuno yokuthumela ngenqanawa kukhokelele ekonyukeni kwee-odolo ezintsha zeenqanawa zamazwe ngamazwe, kuzala “indawo enempumelelo engazange ibonwe iminyaka elishumi” kushishino lokwakha iinqanawa ehlabathini lonke.Kulungile.
Nangona imeko ilungile, ishishini lokwakha iinqanawa lisafuna ukujongana neengxaki ezininzi zokuphucula ishishini phantsi koxinzelelo oluphezulu lokukhuselwa kwendalo.Kwiminyaka yakutshanje, i-International Maritime Organisation (IMO) iye yawukhawulezisa ngokuthe ngcembe umthetho wayo wokukhusela indalo esingqongileyo, kunye nokusebenza kwamandla okufanelekileyo kunye nezalathi zokuqina kwekhabhoni ziseke ngokucacileyo ithayimthebhile yokuqalisa ukusebenza.
Ngexesha elifanayo, injongo ye "carbon peak kunye nokungathathi hlangothi kwekhabhoni" iye yacetywa kwakhona kuphuhliso oluluhlaza kwishishini lokwakha iinqanawa.Ngeemfuno ezintsha, "i-decarbonization" iyimfuneko, kwaye ukusetyenziswa okunzulu kwamandla amatsha, izinto ezintsha kunye nobuchwepheshe obuluhlaza kunye nobukrelekrele buye baba yikhokelo ephambili yokwakhiwa kweenqanawa kunye nokulungiswa kunye nokuthunyelwa kweenqanawa kwixesha elizayo.
Ngokwemveli, ukuhla kwenqanawa yinxalenye ebalulekileyo yokugcinwa nokulungiswa kweenqanawa.Ngaphambili, yayiqhutywa ikakhulu ngehamile yomhlakulo okanye ukuqhushumba komoya.Nangona kunjalo, ngoku kumashishini amakhulu okwakha iinqanawa, ngakumbi nangakumbi ukucocwa kwelaser kusetyenziselwa ukucoca iinqanawa.Ukucoca, kutheni kukho utshintsho olunjalo?Okanye yintoni inzuzooomatshini bokucoca laserxa kuthelekiswa neendlela zokucoca zesintu?
Inkqubo yokucoca yemveli ekwakhiweni kweenqanawa kunye nokulungiswa
Ekwakhiweni kweenqanawa kunye nokulungiswa, kukho inani elikhulu leekhonkco zokucoca, ngokukodwa kubandakanywa ukulungiswa kwangaphambili kwepleyiti yensimbi (phambi kwe-welding nasemva kwe-welding) kunye ne-segmental pretreatment (ngaphambi kokupeyintwa) kweenqanawa ezintsha, kunye nokususwa komhlwa kunye nokususwa ngokubanzi ekulungiseni nasekugcinweni kweenqanawa ezindala.Ipeyinti kunye nokugcinwa kwepeyinti yesibini.
Ukucoca ngokwemveli kunye neenkqubo zokususa ipeyinti ikakhulu zibandakanya ukugaya ngesandla, ukuqhunyiswa kwesanti, ukudubula ukudubula, ukuhlamba kwamanzi kunye nokucoca iikhemikhali.Ezi nkqubo zokucoca zemveli zinokuhlangabezana neemfuno zokucoca i-hull ngokwemigaqo yokusebenza kakuhle kunye nomgangatho wokususwa komhlwa, kodwa ayinakungahoywa.Ewe, zisebenza ngamandla, ukusetyenziswa kwamanzi aphezulu kunye nombane, ngakumbi ukuqhushumba kwesanti kuvelisa umsi omkhulu kunye nothuli, okubangela ungcoliseko olukhulu kwindalo esingqongileyo, kunye nokuphinda kusetyenziswe amanzi amdaka emva kokuhlanjwa kwamanzi ngoxinzelelo oluphezulu, kunye nemisebenzi ethile Iimfuno zococeko eziphezulu azinakugqitywa njl.
Itekhnoloji yokucoca iLaserineenzuzo ezininzi ezifanaakukho monakalo kwi-substrate, ulawulo oluchanekileyo kwinqanaba le-micron, ukugcinwa kwamandla kunye nokukhuselwa kwendalo, ngoko kuye kwaba yindawo yophando kwi-shipbuilding.
1. Ukususwa komhlwa ngesandla
Izixhobo zokususa umhlwa ngesandla zibandakanya iihamile, imihlakulo, iimela zentsimbi, iibhrashi zocingo, njl. njl. Ngokuqhelekileyo, iindawo ezishinyeneyo zerusi zivuthululwa ngehamile emva koko zisuswe ngefotsholo.Amandla aphezulu omsebenzi kunye nokusebenza kakuhle kokususa umhlwa.
2. Ukususwa komhlwa koomatshini
(1) Ukususwa kwerusi encinci ye-pneumatic okanye yombane;(2) Ukuchama kweembumbulu (isanti) ukususwa komhlwa;
(3) Ukutshatyalaliswa ngamanzi oxinzelelo oluphezulu;(4) Ukonakalisa ngokuqhushumba.
3. Ukususwa komhlwa ngeekhemikhali
Ikakhulu yindlela yokususa i-rust esebenzisa i-chemical reaction phakathi kwe-asidi kunye nee-oxide zetsimbi ukususa umhlwa kwi-metal surface, oko kukuthi, okubizwa ngokuba yi-pickling kunye nokususwa kwe-rust, enokuthi iqhutywe kuphela kwi-workshop.Ukususwa komhlwa ngekhemikhali kunomngcipheko omkhulu, ungcoliseko olumandla lwemo engqongileyo, kwaye akuvumelekanga ukuba kusetyenziswe.
4. Ukususwa komhlwa kweLaser
Ukususwa kwe-laser rust yiteknoloji entsha eluhlaza, ehambelana nokusingqongileyo, esebenzayo kwaye ekhuselekileyo, eya kuthi kungekudala ithathe indawo yeenkqubo ezingentla kwaye isetyenziswe ngokubanzi.Ngokukodwa ekususweni kwepeyinti, ukususwa kwe-oyile, ukucocwa komphetho kunye nokususwa komhlwa, kunye nokususwa kwe-oxyde layer, ukucocwa kwe-laser kuya kudlala indima engenakubuyiselwa.
Ngokusekelwe kwinyaniso engasentla, phantsi kweemfuno zemigangatho emitsha ye-EIA, amashishini okwakha iinqanawa kufuneka afune ngenkuthalo iinkqubo ezintsha zokucoca, ezisebenzayo nezicocekileyo kunye neendlela zokusombulula iintlungu zeshishini.
Ukucocwa kweLaser kwenza ukucoca iinqanawa kube yinto ebalulekileyo
Kwiminyaka yakutshanje, phantsi kobhengezo lokusebenza kakuhle kakhulu, ukonga amandla kunye nokukhuselwa kwendalo ukukhuthaza uphuhliso lweshishini, itekhnoloji yokucoca ngelaser iye yavela ngokuthe ngcembe kwizicelo eziphezulu ezifana nezithuthi zamandla amatsha, i-aerospace, kunye ne-elektroniki echanekileyo. iboniswe ngakumbi nangakumbi yesakhono sokwenza isicelo kushishino lolwakhiwo lweenqanawa.
Itekhnoloji yokucoca i-laser ineenzuzo ezininzi ezinjengokungabikho monakalo kwi-substrate, ulawulo oluchanekileyo kwinqanaba le-micron, ukonga amandla kunye nokukhuselwa kwendalo, njl., kwaye inokuhlangabezana ngokupheleleyo neemfuno zokususwa komhlwa kuzo zonke iiprofayili zetsimbi kunye nokulungiswa kwangaphambili nasemva kwe-welding.
Ngokumalunga nokugcinwa kweenqanawa, ukucocwa kwe-laser, njengeteknoloji yokucoca "i-high-precision" yokucoca, ifanelekile ukukrazula i-rust kunye nepeyinti kwiindawo zeekhabhini, iitanki ze-ballast, iitanki zamafutha, njl., kunye nokucocwa kwekhabhoni. iidiphozithi ezifana ne-injini ye-diesel ye-injini ye-cylinder valves Ayilimazi i-substrate, kwaye inokujongana nezikhewu ezincinci ngaphandle kwemiqobo yokususa ngokuchanekileyo isikali, umgangatho wokucoca ophezulu, ukonga amandla kunye nokukhuselwa kwendalo.
Ukuba ufuna ukufunda ngakumbi malunga nokucoca i-laser, okanye ufuna ukukuthengela umatshini wokucoca i-laser, nceda ushiye umyalezo kwiwebhusayithi yethu kwaye usithumelele i-imeyile ngqo!
