Imiba ephambili echaphazela uMgangatho weWeld
Emva kwe-welding, i-original tin layer yokukhusela kwi-weld seam isuswe ngokupheleleyo, ishiya kuphela isiseko sentsimbi.
Ngoko ke, kufuneka igutyungelwe nge-high-molecular organic coating ukuthintela ukubola ekudibaneni phakathi kwentsimbi kunye neziqulatho kunye nokuphepha ukuguqulwa kombala okubangelwa ukubola.
1. Iindidi zeeCoatings
Iingubo zokulungisa zinokwahlulwa zibe ziingubo zolwelo kunye neengubo zomgubo. Uhlobo ngalunye luneempawu ezizodwa ngenxa yokungafani kokwakheka, ukusetyenziswa, kunye neenkqubo zokunyanga.
1. IiNgqungquthela eziManzi
Ezi ziquka i-epoxy phenolic, i-acrylic, i-polyester, i-organosol, kunye neengubo ezinemibala, ezifanelekileyo ukulungiswa kwe-weld seam kwizinto ezininzi zokutya kunye neziselo zesiselo.
▶ I-Epoxy Phenolic Coatings: Zine-micropores ezimbalwa, iikhemikhali ezigqwesileyo kunye nokumelana nokubulala inzala, kodwa zifuna ubushushu obuphezulu bokubhaka. Ukubhaka okungonelanga kukhokelela ekunyangeni okungaphelelanga, okubangela ukuba i-coating ibe mhlophe emva kokuvala inzala, echaphazela ukusebenza kunye nokhuseleko lokutya. Ukubhaka okugqithisileyo kunciphisa ukuguquguquka kunye nokunamathela, okwenza i-coating brittle kwaye ithande ukuqhekeka.
▶ I-Acrylic kunye ne-Polyester Coatings: Inika ukunamathela okugqwesileyo, ukuguquguquka, ukuxhathisa iikhemikhali, kunye nokumelana nokuvala inzala. Nangona kunjalo, iingubo ze-acrylic zinokufunxa imibala yokutya kwaye zibe nokumelana okulinganiselweyo kwi-corrosion ye-sulfide.
▶ Iiyaleko ze-Organosol: Ziphawulwa ngomxholo oqinileyo ophezulu, zenza iingubo ezishinyeneyo kwi-weld seams ngaphandle kwamaqamu, kunye nokuguquguquka okugqwesileyo kunye nokuqhubekeka. Zifuna ubushushu obuncinci bokubhaka kunezinye iingubo kodwa zinokumelana nokungena okungahambi kakuhle kwaye zithandeka kwi-corrosion ye-sulfide, zibenza bangafaneleki ukutya okunesulfure.
▶ Iingubo ezinombala obomvu: Zenziwa ngokugalela ititanium dioxide okanye umgubo wealuminiyam kwi-organosol, epoxy, okanye kwi-polyester yokwambathisa ukuze kugqunywe iindawo ezinomhlwa phantsi kwefilim, ezilungele ukulungiswa komthungo kwiitoti ezifana nenyama yesidlo sasemini.
2. Iingubo zomgubo
Iingubo zomgubo zenza iifilimu ezingqingqwa, ezipheleleyo, ezibonelela ngokhuseleko olululo lwemithungo ye-weld. Abanakho ukukhutshwa kwe-solvent ngexesha lokucutshungulwa, ukunciphisa ukungcoliseka kwendalo, kwaye basetyenziswa ngokubanzi kwiitoti zokutya kunye neziselo ezineemfuno zokumelana nokugqwala okuphezulu.Ii-powder coatings zihlukaniswe kwiintlobo ze-thermoplastic kunye ne-thermosetting.
▶ I-Thermoplastic Coatings: Ikakhulu yenziwe nge-polyester powder, i-titanium dioxide, i-barium sulfate, njl njl. Ukubunjwa kwefilimu yinkqubo elula yokunyibilika, ngoko ke ngexesha lokubhaka emva kokutshiza okugcweleyo, xa ubushushu bufikelela kwindawo yokunyibilika kwepowder coating, i-coating yokulungiswa iya kuphinda iphinde ifake. Ezi zambatho zibhetyebhetye kakhulu kwaye zimelana neenkqubo ezahlukeneyo zoomatshini kodwa zinokumelana neekhemikhali ezihlwempuzekileyo kunezogquma ze-thermosetting, ezifunxa lula imibala yokutya. Ukubambelela kwabo kwisiseko sokwaleka kuphantsi kunomthungo we-weld, okukhokelela kwibhulorho efana ne-arch shape.
▶ I-Thermosetting Coatings: Ikakhulu yenziwe nge-epoxy/polyester, zinyangwa kwiikhompawundi zemolekyuli ephezulu ngokwenziwa kwepolymerization emva kokufudumeza, zenza iifilimu ezibhityileyo kuneengubo ze-thermoplastic ezinokumelana nekhemikhali okugqwesileyo kodwa ukuqhubekeka okuphantsi.
Iingubo zokulungisa zinokwahlulwa zibe ziingubo zolwelo kunye neengubo zomgubo. Uhlobo ngalunye luneempawu ezizodwa ngenxa yokungafani kokwakheka, ukusetyenziswa, kunye neenkqubo zokunyanga.

2. Iingubo zomgubo
Iingubo zomgubo zenza iifilimu ezingqingqwa, ezipheleleyo, ezibonelela ngokhuseleko olululo lwemithungo ye-weld. Abanakho ukukhutshwa kwe-solvent ngexesha lokucutshungulwa, ukunciphisa ukungcoliseka kwendalo, kwaye basetyenziswa ngokubanzi kwiitoti zokutya kunye neziselo ezineemfuno zokumelana nokugqwala okuphezulu.Ii-powder coatings zihlukaniswe kwiintlobo ze-thermoplastic kunye ne-thermosetting.

2. Ukutyeba kokugquma
3. Ingqibelelo yoKwaleka
1. Umgangatho weWeld
Ukunyaniseka kweengubo zokulungisa ulwelo ubukhulu becala kuxhomekeke kwimilo yejometri ye-weld seam. Ukuba i-weld seam ineendawo zokutshiza, i-extrusion enzima, okanye indawo erhabaxa, iingubo zolwelo azikwazi ukuyigubungela ngokupheleleyo. Ukongezelela, ubukhulu bomthungo we-weld buchaphazela umphumo wokugubungela; ngokubanzi, umthungo umthungo ubukhulu kufuneka ngaphantsi kwe 1.5 amaxesha ubukhulu ipleyiti. Kwintsimbi yesibini eqengqelekayo ebandayo okanye intsimbi enobunzima obuphezulu, ubukhulu be-weld seam yi-1.5 ukuya kwi-1.8 ngokuphindwe kabini ubukhulu bepleyiti.
Imithungo ye-weld eyenziwe ngaphandle kokukhuselwa kwe-nitrogen ingaba nokubambelela kakubi kwengubo yokulungisa ngenxa yobuninzi be-oxide layers, ekhokelela ekufakeni iintanda ngexesha leenkqubo ezilandelayo ezifana ne-flanging, i-necking, kunye ne-beading, echaphazela ukunyaniseka kwengubo yokulungisa.
Iingubo zePowder, ngenxa yobuninzi babo obaneleyo, ziyakwazi ukujongana ngokugqibeleleyo nemiba yokuvezwa kwesinyithi ebangelwa yiziphene ze-weld, inika ukhuseleko oluhle kakhulu kwi-weld seam.
2. Amaqamza
Ukuqulunqwa kwe-solvent engenangqiqo kwiingubo zokulungisa ulwelo kunokuchaphazela ukunyaniseka kwengubo. Xa iingubo zolwelo ziqulethe i-solvents encinci yokubilisa, okanye ukuba iqondo lokushisa liphakama ngokukhawuleza ngexesha lokubhaka, okanye ukuba i-weld seam ye-weld iphezulu kakhulu, isixa esikhulu se-solvent siphuphuma ngexesha lokubhaka, sishiya imitya ye-bubbles okanye i-micropores kwi-coating, ukunciphisa ukugubungela kunye nefuthe lokukhusela kwi-weld seam.
4. Ukubhaka kunye nokuNyanga
1. Inkqubo yokuNyanga yokuLungisa iiCoatings
Ukubhaka kunye nokunyangwa kweengubo zolwelo kunokwahlulwa ngokwezigaba ngokwala manqanaba alandelayo: amanqanaba okuqala okwambathisa kunye nokumanzisa i-weld seam kunye neendawo ezingenanto (malunga nemizuzwana eyi-1-2), ilandelwa ngumphunga we-solvent ukuze wenze ijeli (kufuneka igqitywe kwimizuzwana emi-3-5; kungenjalo, ukugquma kuya kuhamba kumthungo we-weld), kwaye ekugqibeleni i-polymerization. Ukugqoka kufuneka kufumane ukushisa okwaneleyo, okuchaphazela kakhulu ubukhulu kunye nokusebenza kwengubo yokulungisa. Njengoko bekutshiwo ngaphambili, ukunyuka kwamaqondo obushushu okukhawulezayo ngexesha lokubhaka kunokuvelisa amaqamza ngokulula, ngelixa ukunyuka kobushushu obucothayo kunokubangela ukunyanga okunganelanga ngenxa yokugcinwa kobushushu obufutshane.
Iingubo ezihlukeneyo zineenguqu ezihlukeneyo ngexesha lokubhaka; I-epoxy phenolic coatings ifuna ixesha elide kune-organosol coatings, oku kuthetha ukuba bafuna ubushushu obuninzi bokubhaka.
Ukugquma umgubo, iingubo ze-thermoplastic zinyibilika zenze ifilimu ngexesha lokubhaka ngaphandle kwe-polymerization, ngelixa iingubo ze-thermosetting zingena kwi-polymerization eyongezelelweyo emva kwe-polymerization yangaphambili kunye nokunyibilika kwi-crosslink kwi-high-molecular compounds. Ngoko ke, ukushisa kokubhaka kuhambelana ngokusondeleyo nokusebenza kwengubo yokulungisa.
2. Impembelelo yeSidanga seCuring kwi-Coating Performance
Iingubo zokulungisa zingabonisa kuphela iimpawu zabo xa zibhaka ngokupheleleyo kwaye zinyangwa. Ukubhaka okungonelanga kukhokelela kwii-micropores ezininzi kunye nokungahambi kakuhle; umzekelo, umgubo we-thermoplastic ongabhakwanga ngokwaneleyo unokushwabana ngexesha le-flanging. Ukubhaka okugqithisileyo kuchaphazela ukunamathela; umzekelo, iingubo ezigqithisiweyo ze-epoxy phenolic ziba brittle kwaye zithambekele ekuqhekekeni ngexesha lokuguqa, ukugoba, kunye nokubhida. Ukongezelela, ukupholisa okwaneleyo emva kokubhaka kubalulekile ekusebenzeni kwengubo yokulungisa. Ngokomzekelo, ukuba i-thermoplastic powder coatings ayipholi ngokukhawuleza kwiqondo lokushisa legumbi emva kokubhaka, i-coating ingaqhekeka ngexesha lokutshisa. Ukongeza isixhobo sokupholisa emva kwe-oven kunokuthintela imiba yokuqhekeka kwi-coating yokulungisa ngexesha lokutshisa.
Isishwankathelo, ukuqinisekisa umgangatho wokulungiswa komgangatho-oko kukuthi, i-porosity ephantsi kunye ne-processability elungileyo-kuyimfuneko ukulawula ubukhulu kunye neqondo lokuphilisa le-coating.
