UThintelwa Njani uPowder Coating Caking
Indlela yokuthintela yengubo ukuqhuba
Iintlaka ezahlukeneyo ezinamaqondo obushushu okutshintsha kweglasi ahlukeneyo, njengeepoxy kunye nepolyester resin ineqondo lobushushu leglasi elimalunga nama-50 degrees Celsius, iarhente yokukhanyisa (701) inobushushu beglasi obumalunga nama-30 ngokukaCelsius, iarhente yokulinganisa ulwelo kwiminus degrees Celsius.
Ubukhulu bexabiso lezinto ezinobushushu obuphantsi beglasi eguquguqukayo kwimixube yokwaleka yomgubo iqulathe, okuya kusezantsi iqondo lobushushu begilasi liya kuba .Iqondo lobushushu beglasi lilinganiswa ngesixhobo esikhulu esizinikeleyo, ijini elenza umgubo wokugquma.rally abanazo ezi zixhobo ezibizayo, kwaye kwinkqubo yokuvelisa abanakukwazi ukubamba ubushushu beglasi yenguqu yomgubo, ngoko ke, kwimveliso yenkqubo yomgubo ebekwe malunga nobushushu beglasi ye-40 ° C, iqondo lokushisa lomgubo i-caking njengobushushu obukhuselekileyo. Emva koko kwimveliso ( kunye nokugcinwa kwemveliso kunye nenkqubo yokuthutha ) njengomgangatho , kufutshane nangaphezulu kolu bushushu abasebenzi abafanelekileyo kufuneka bomeleze isampuli yemveliso ye-caking .Ngokukodwa ehlotyeni, ingxaki ye-caking yenzeka ngokulula ngenxa yokunyuka kwamaqondo obushushu, ngoko indlela ukunqanda ukugquma umgubo ukucaka?
Okokuqala, ukugquma komgubo kwiqondo elithile lobushushu ngumthetho wendalo. Ukuthintela i-caking powder ukutyabeka, imveliso kufuneka yokugaya, ukupakishwa, ukugcinwa, ukuthutha, kwaye ke yonke le nkqubo, iimveliso zokugquma umgubo kwiqondo lokushisa lokutshintsha kweglasi.
Ngokwalo mbono kukho ezi zisombululo zilandelayo:
- Kwimveliso ye-polyester resin, ukukhethwa kwezinye iiglasi zeqondo lokushisa kunokunyusa utywala okanye i-asidi, okanye ukunciphisa ukusetyenziswa kwe-resin, i-glass transition yeqondo lokushisa ukunciphisa ubuninzi botywala ukunyusa ubushushu beglasi ye-polyester resin.
- Kukwenziwa komgubo wokugquma ukwehlisa iglasi ephantsi yokutshintsha ubushushu bepolymer isetyenziswa ngokwexabiso , njengee-arhente zokulinganisa kunye ne-ejenti yokukhanyisa ukuqinisekisa ukuba inkqubo yokugquma umgubo ayinciphisi iqondo lobushushu beglasi.
- Imveliso, eyaphukileyo kwi-strip sheet impahla kufuneka ipholiswe ngokwaneleyo ngaphambi kokungena kwinkqubo yokugaya, ukugaya kufuneka kube ngokufanelekileyo ukunciphisa izinga lokutya, ukwandisa i-lead damper yomoya, i-inlet air ukulawula ukufakwa kweqondo lokushisa lomoya womoya. Nangona kunjalo, ukuba iiflakes zangaphambili ezityunyuziweyo zibambelele ekupholiseni, le yokugqibela ayinakukwazi ukudlala indima enhle, qwalasela iiflakes ezityumkileyo kwindlela yokupholisa ngokunyanzeliswa unyango lwe-cryogenic, olusebenza ngakumbi kunokubuyisela kwakhona.
Ukongezelela, izongezo ezichasene ne-caking zingongezwa, ezifana ne-nanosilica (VK-SP15) okanye i-nano-aluminium oxide (VK-L20M) powder ukukhusela ukunamathela phakathi kwamasuntswana omgubo, i-anti-caking agents ziyi-gene.rally ngaxeshanye kwaye iiflakes ezaphukileyo zokugaya best.
Lilonke, kwimveliso, abasebenzi abafanelekileyo kufuneka benze isampulu engqongqo ukunqanda ukugquma komgubo.
