Izinto Eziphambili Ezichaphazela Umgangatho Weld
Emva kokuwelda, umaleko wokuqala wetin okhuselayo kumthungo we-weld ususwa ngokupheleleyo, kushiyeke isinyithi esisisiseko kuphela.
Ngoko ke, kufuneka igqunywe nge-molecule ephezulu ye-organic coating ukuthintela ukugqwala ekudibaneni kwentsimbi kunye nomxholo kunye nokuphepha ukutshintsha kombala okubangelwa kukugqwala.
1. Iintlobo zeengubo
Iingubo zokulungisa zinokwahlulwa zibe ziingubo zolwelo kunye neengubo zomgubo. Uhlobo ngalunye luneempawu ezizodwa ngenxa yokwahluka kwendlela ezibunjwe ngayo, ezisetyenziswa ngayo, kunye neenkqubo zokunyanga.
1. Iingubo zolwelo
Ezi ziquka i-epoxy phenolic, i-acrylic, i-polyester, i-organosol, kunye neengubo ezinombala, ezifanelekileyo ukulungiswa komthungo we-weld kwiinkonkxa ezininzi zokutya neziselo.
▶ Ii-Epoxy Phenolic Coatings: Zine-micropores ezimbalwa, ziyakwazi ukumelana neekhemikhali kunye nokubulala iintsholongwane, kodwa zifuna ubushushu obuphezulu bokubhaka. Ukubhaka okunganelanga kukhokelela ekungaphelelini kakuhle, okubangela ukuba i-coat ibe mhlophe emva kokubulala iintsholongwane, okuchaphazela ukusebenza kunye nokhuseleko lokutya. Ukubhaka kakhulu kunciphisa ukuguquguquka kunye nokunamathela, okwenza i-coat ibe buthathaka kwaye ithambekele ekuqhekekeni.
▶ Iingubo ze-Acrylic kunye nePolyester: Zibonelela ngokunamathela okuhle kakhulu, ukuguquguquka, ukumelana neekhemikhali, kunye nokumelana nokubulala iintsholongwane. Nangona kunjalo, iingubo ze-acrylic zinokufunxa imibala yokutya kwaye zingamelani nokugqwala kwe-sulfide.
▶ Iingubo ze-Organosol: Zibonakala ngomxholo ophezulu oqinileyo, zenza iingubo ezixineneyo kwi-weld seams ngaphandle kwamaqamza, zinokuguquguquka okugqwesileyo kunye nokusebenziseka lula. Zifuna ubushushu obuncinci bokubhaka kunezinye iingubo kodwa azinawo amandla okungena kwaye zisengozini yokubola kwe-sulfide, nto leyo eyenza ukuba zingafaneleki ukutya okune-sulfur.
▶ Iingubo Ezinemibala: Ngokwesiqhelo zenziwa ngokongeza i-titanium dioxide okanye umgubo we-aluminium kwiingubo ze-organosol, epoxy, okanye ze-polyester ukufihla amabala okugqwala phantsi kwefilimu, ezifanelekileyo ukulungiswa komthungo we-weld kwiitini ezifana nenyama yesidlo sasemini.
2Iingubo zomgubo
Iingubo zomgubo zenza iifilimu ezingqindilili nezipheleleyo, ezibonelela ngokhuseleko olungcono kwii-weld seams. Azinazo izinyibilikisi ezikhutshwayo ngexesha lokucubungula, zinciphisa ungcoliseko lokusingqongileyo, kwaye zisetyenziswa kakhulu kwiitini zokutya neziselo ezineemfuno eziphezulu zokumelana nokugqwala. Iingubo zomgubo zahlulwe zibe ziintlobo ze-thermoplastic kunye ne-thermosetting.
▶ Iingubo zeThermoplastic: Ziqulathe ikakhulu umgubo wepolyester, i-titanium dioxide, i-barium sulfate, njl. Ukwenziwa kwefilimu yinkqubo elula yokunyibilika, ngoko ke ngexesha lokubhaka emva kokutshiza nge-full-can, xa ubushushu bufikelela kwinqanaba lokunyibilika kwengubo yepowder, ingubo yokulungisa iya kunyibilika kwaye yakheke. Ezi ngubo ziguquguquka kakhulu kwaye zimelana neenkqubo ezahlukeneyo zoomatshini kodwa zinokumelana okuphantsi kweekhemikhali kuneengubo zethermosetting, zifunxa ngokulula imibala yokutya. Ukunamathela kwazo kwingubo esisiseko kuphantsi kune-weld seam, nto leyo ebangela ukuba zibe yi-arch efana nebhulorho.
▶ Iingubo zokubeka iThermosetting: Ngokuyintloko zenziwe nge-epoxy/polyester, ziyanyangeka zibe ziikhompawundi ezineemolekyuli eziphezulu ngokusebenzisa i-polymerization emva kokufudumeza, zenze iifilimu ezincinci kuneengubo ze-thermoplastic ezinokumelana okuhle kweekhemikhali kodwa zingenakusebenza kakuhle.
Iingubo zokulungisa zinokwahlulwa zibe ziingubo zolwelo kunye neengubo zomgubo. Uhlobo ngalunye luneempawu ezizodwa ngenxa yokwahluka kwendlela ezibunjwe ngayo, ezisetyenziswa ngayo, kunye neenkqubo zokunyanga.

▶ Iingubo ze-Organosol: Zibonakala ngomxholo ophezulu oqinileyo, zenza iingubo ezixineneyo kwi-weld seams ngaphandle kwamaqamza, zinokuguquguquka okugqwesileyo kunye nokusebenziseka lula. Zifuna ubushushu obuncinci bokubhaka kunezinye iingubo kodwa azinawo amandla okungena kwaye zisengozini yokubola kwe-sulfide, nto leyo eyenza ukuba zingafaneleki ukutya okune-sulfur.

2. Ubukhulu bokugquma
3. Ukunyaniseka kokuGcoba
1. Umgangatho weWeld
Ukuthembeka kweengubo zokulungisa ulwelo kuxhomekeke kakhulu kwimo yejometri yomthungo we-weld. Ukuba umthungo we-weld uneendawo zokutshiza, ukuphuma okukhulu, okanye umphezulu orhabaxa, iingubo zolwelo azinakuwugubungela ngokupheleleyo. Ukongeza, ubukhulu bomthungo we-weld buchaphazela isiphumo sokugquma; ngokubanzi, ubukhulu bomthungo we-weld kufuneka bube ngaphantsi kwe-1.5 ubukhulu beplate. Kwintsimbi yesibini eqengqelekayo ebandayo okanye intsimbi yokuqina okuphezulu, ubukhulu bomthungo we-weld buphindwe kayi-1.5 ukuya kwi-1.8 ubukhulu beplate.
Ii-weld seams ezenziwe ngaphandle kokukhuselwa yi-nitrogen zinokuba nokunamathelana okungalunganga kwe-repair coating ngenxa yee-oxide layers ezininzi, nto leyo ekhokelela kwii-coating crack ngexesha leenkqubo ezilandelayo ezifana ne-flanging, necking, kunye ne-beading, nto leyo echaphazela ukuthembeka kwe-repair coating.
Iingubo zomgubo, ngenxa yobukhulu bazo obaneleyo, zinokujongana ngokugqibeleleyo neengxaki zokuvezwa kwesinyithi ezibangelwa ziziphene ze-weld, zibonelela ngokhuseleko olugqwesileyo kumthungo we-weld.
2. Amaqamza
Iifomyula ze-solvent ezingenangqondo kwiingubo zokulungisa ulwelo zinokuchaphazela ukuthembeka kwengubo. Xa iingubo zolwelo ziqulethe izinyibilikisi ezingaphezulu ezibila kancinci, okanye ukuba ubushushu bunyuka ngokukhawuleza ngexesha lokubhaka, okanye ukuba ubushushu be-weld seam buphezulu kakhulu, isixa esikhulu se-solvent siyaphela ngexesha lokubhaka, sishiya imicu yamaqamza okanye ii-micropores kwingubo, nto leyo enciphisa ukugquma kunye nefuthe lokukhusela kwi-weld seam.
4. Ukubhaka nokuPhilisa
1. Inkqubo Yokulungisa Iingubo Zokulungisa
Ukubhaka kunye nokucocwa kweengubo zolwelo kunokwahlulwahlulwa ngokwamanqanaba alandelayo: upende kuqala ulinganise kwaye umanzise umthungo we-weld kunye neendawo ezingenanto (malunga nemizuzwana eyi-1-2), kulandele ukufuma kwe-solvent ukwenza ijeli (kufuneka kugqitywe kwimizuzwana emi-3-5; kungenjalo, upende uya kuphuma kumthungo we-weld), kwaye ekugqibeleni upholimeyitha. Upende kufuneka ufumane ubushushu obaneleyo, obuchaphazela kakhulu ubukhulu kunye nokusebenza kopende wokulungisa. Njengoko bekutshiwo ngaphambili, ukunyuka kobushushu ngokukhawuleza ngexesha lokubhaka kunokuvelisa amaqamza ngokulula, ngelixa ukunyuka kobushushu okucothayo kunokubangela ukungomelelani ngenxa yokugcinwa kobushushu obufutshane.
Iingubo ezahlukeneyo zinexesha eliphantsi lokubhaka; iingubo ze-epoxy phenolic zifuna ixesha elide kuneengubo ze-organosol, oko kuthetha ukuba zifuna ubushushu obuninzi xa zibhaka.
Kwizinto ezigqunywe ngomgubo, izinto ezigqunywe ngobushushu be-thermoplastic ziyanyibilika nje ukuze zenze ifilimu ngexesha lokubhaka ngaphandle kokugqunywa, ngelixa izinto ezigqunywe ngobushushu be-thermosetting zigqunywa emva kokugqunywa ngaphambi kokugqunywa kwaye zinyibilike ziye kwi-crosslink zibe zii-molecules eziphezulu. Ke ngoko, ubushushu bokubhaka bunxulumene ngokusondeleyo nokusebenza kwento egqunywe ngobushushu.
2. Impembelelo yeDigri yokuPhilisa kwiNdlela yokuGcoba
Iingubo zokulungisa zinokubonisa iimpawu zazo kuphela xa zibhakiwe ngokupheleleyo kwaye zicociwe. Ukubhaka okunganelanga kukhokelela kwiintsholongwane ezininzi kunye nokungaqhubi kakuhle; umzekelo, iingubo zomgubo we-thermoplastic ezingabhakwanga ngokwaneleyo zinokushwabana ngexesha lokutshaya. Ukubhaka okugqithisileyo kuchaphazela ukunamathela; umzekelo, iingubo ze-epoxy phenolic ezibhakiweyo kakhulu ziba buthathaka kwaye ziqhekezeke ngexesha lokutshaya, ukugoba, kunye nokutshaya. Ukongeza, ukupholisa okwaneleyo emva kokubhaka kubalulekile ekusebenzeni kwengubo yokulungisa. Umzekelo, ukuba iingubo zomgubo we-thermoplastic azipholiswanga ngokukhawuleza ukuya kubushushu begumbi emva kokubhaka, ingubo inokwaphuka ngexesha lokutshaya. Ukongeza isixhobo sokupholisa emva kwe-oven kunokuthintela iingxaki zokuqhekeka kwingubo yokulungisa ngexesha lokutshaya.
Ngamafutshane, ukuqinisekisa umgangatho wengubo yokulungisa—oko kukuthi, ukuvuleka okuphantsi kunye nokusebenziseka kakuhle—kubalulekile ukulawula ubukhulu kunye nomgangatho wokuchacha kwengubo.
