Izinto zokugquma umgubo namhlanje nangomso

Namhlanje, abavelisi be yengubo izinto ziye zasombulula iingxaki zexesha elidlulileyo, kwaye uphando oluqhubekayo kunye nobuchwepheshe buqhubeka nokudiliza imiqobo embalwa eseleyo kwi-powder coating.

Izinto zokugquma umgubo

Eyona nto ibalulekileyo ephunyelelweyo ibe luphuhliso lweenkqubo zobunjineli ze-resin ezenzelwe ukuhlangabezana neemfuno ezahlukeneyo kunye nezikhethekileyo zeshishini lokugqiba isinyithi. Iiresin ze-epoxy zazisetyenziswa phantse kuphela kwiminyaka yokuqala yokwaleka kwe-thermosetting powder kwaye zisasetyenziswa ngokubanzi namhlanje. Ukusetyenziswa kweentlaka zepolyester kukhula ngokukhawuleza kwimarike yaseMntla Melika kwaye ii-acrylics ziyinto enkulu kubasebenzisi abaninzi bokugqibela, njengesixhobo sombane kunye nemizi-mveliso yeemoto.

Iipowders ziyafumaneka ngokuxhathisa okugqwesileyo ku-corrosion, ubushushu, impembelelo, kunye nokuqhawuka. umbala ukhetho alunamda ngeglosi ephezulu nesezantsi, kunye nokugqitywa okucacileyo okukhoyo. Ukhetho lokuthungwa lusuka kwiindawo ezigudileyo ukuya kwindawo eshwabeneyo okanye esematheni. Ubukhulu befilimu bunokwahluka ukuze buhambelane neemfuno zezicelo ezithile.

Ukuphuhliswa kweenkqubo zeresin kubangele i-epoxy-polyester hybrid, enika umaleko obhityileyo, ophantsi- ~ onyangayo ogqume ngomgubo. Ukuqhubela phambili kwi-polyester kunye ne-acrylic resins kuphuculwe ukuqina kwangaphandle kwezi nkqubo. Inkqubela phambili ethile kwitekhnoloji ye-resin ibandakanya:

• Iingubo ze-Thin-layer powder ezisekelwe kwi-epoxy-polyester hybrids zibonelela ngezicelo kuluhlu lwe-1 ukuya kwi-1.2 mils ngemibala enegunya elihle lokufihla. Ezi filimu zibhityileyo okwangoku zilungele usetyenziso lwangaphakathi kuphela. Iifilimu ezincinci kakhulu, ezinokufuna i-powder grinds ekhethekileyo, ingaba ngaphantsi kwe-0.5 mils.
• Iingubo eziphantsi zobushushu obuphantsi. Iingubo zePowder ezine-reactivity ephezulu ziye zaphuhliswa ukunyanga kumaqondo obushushu angaphantsi kwe-250 ° F (121 ° C). I-powders enjalo ephantsi yokunyanga yenza isantya esiphezulu somgca, ukwandisa umthamo wemveliso ngaphandle kokubingelela ukuqina kwangaphandle. Bakwanyusa inani le substrates ezinokuthi zifakwe ngumgubo, ezifana ezinye iiplastiki kunye neemveliso zokhuni.
• Iingubo zepowder texture. Ezi zogquma ngoku zisusela kuthungelwano olucokisekileyo oluneglosi ephantsi kunye nokumelana okuphezulu nokurhawuka kunye nemikrwelo, ukuya kuthungelwano olurhabaxa oluluncedo ekufihleni umphezulu ongalinganiyo wezinye substrates. Ezi ngubo zokuthungwa ziye zaphuculwa kakhulu xa kuthelekiswa neendawo zabo zokubala ze-sevenral Kwiminyaka eyadlulayo.
• Iingubo zomgubo ezikhanyayo eziphantsi. Ngoku kunokwenzeka ukunciphisa amaxabiso eglosi ngaphandle kokunciphisa ukuguquguquka, iimpawu zomatshini, okanye ukubonakala kweengubo zomgubo. Amaxabiso eglosi anokuthotywa ukuya kwi-1% okanye ngaphantsi kwii-epoxies ezicocekileyo. Iglosi ephantsi kakhulu kwiinkqubo zepolyester ezichasene nemozulu malunga ne-5%.
• Iingubo zomgubo wesinyithi okwangoku ziyafumaneka ngoluhlu lwemibala. Uninzi lwezi nkqubo zesinyithi zifanelekile kwisicelo sangaphandle. Ukomelela kwangaphandle okugqwesileyo, idyasi ecacileyo yomgubo idla ngokusetyenziswa ngaphezulu kwesiseko sesinyithi. Iinzame zijolise ekuphuhliseni imidlalo egqibeleleyo yemibala ye-anodizing esemgangathweni ukuhlangabezana neemfuno zemakethi ye-aluminium extrusion. Olunye uphuhliso lwakutsha nje kukutshintshwa kwee-flakes zetsimbi kunye nezinto ezingenayo i-ferrous ezifana ne-mica.
• Iingubo ezicacileyo zomgubo ziye zaphuculwa kakhulu kwixesha elidlulileyoral iminyaka malunga nokuhamba, ukucaca, kunye nokumelana nemozulu. Ngokusekwe kwi-polyester kunye ne-acrylic resins, ezi powders ezicacileyo zibeka imigangatho yomgangatho kumavili emoto, izixhobo zemibhobho, ifenitshala kunye ne-hardware.
• Ubume bezulu obuphezulu bokugquma umgubo. Ukuqhubela phambili okumangalisayo kwenziwe ekuphuhliseni ipolyester kunye ne-acrylic resin iinkqubo ezinobumo bezulu obugqwesileyo bexesha elide ukuhlangabezana neziqinisekiso ezandisiweyo ezibonelelwa ngabavelisi. Kwakhona phantsi kophuhliso kukho umgubo osekelwe kwi-fluorocarbon, oya kuhambelana okanye ugqithise ubume bezulu be-fluorocarbons engamanzi, kunye neendleko ezisetyenzisiweyo ezinenzuzo kumgubo.

Ukugquma ngomgubo kuye kwaba sisiphelo esisebenzayo kwiimveliso ezivelisa amanqanaba obushushu abalulekileyo, afana nezibane zentengiso, kunye ne kuqala kwi-grill top, apho isebenza njengesiseko sengubo ephezulu yolwelo.

Abavelisi bePowder bayaqhubeka besenza intlaka egqibeleleyo kunye noyilo lweearhente zokunyanga. Iinzame zophando zangoku zijolise ekuphuhliseni nasekuphuculeni ixabiso eliphantsi, i-powders yokunyanga i-powder ephantsi ukunceda ukwandisa isicelo sokugquma umgubo kwii-substrates ezintsha. Umsebenzi uyaqhubeka ekuphuhliseni umgubo ohlala ixesha elide kunye nemozulu ephezulu ukuze isetyenziswe ngaphandle, ebonisa ukuxhathisa okuphezulu ekutshitshweni okanye ukufiphala kukukhanya kwelanga.
