Uvavanyo lokugoba kunye nokuncamathela kweFBE yomgubo wokwaleka
Ukunamathela kwi-FBE powder coating I-cupping tester isetyenziselwa ukumisela ukunamathela kwe-FBE powder coating, kunye ne-Fig.7 ibonisa umgaqo wokuvavanya umhloli wekomityi. Intloko yokuvavanya i-cupping tester i-spherical, ityhala ngasemva kweepaneli ezigqunyiweyo ukuvavanya ukuba ifilimu eqinisekileyo iyaqhekeka okanye yahlulwe kwi-substrate. I-Fig.8 yisiphumo sovavanyo lwe-cupping ye-epoxy powder coating. Kwakubonakala ukuba i-FBE powder coatings engazaliswanga nayoFunda ngokugqithisileyo …
Ukulungiswa kweCarboxylterminated ye Fusion-bonded-epoxy Powder Coating
Ukulungiswa kunye nokuPhathwa kweCarboxylterminated Poly (butadiene-co-acrylonitrile) -epoxy Resin Prepolymers for Fusion-bonded-epoxy Powder Coating 1 Intshayelelo Iingubo zomgubo zeFusion-bonded-epoxy (FBE) ezathi zaphuhliswa okokuqala yi-3M Co. ukhuseleko lomhlwa ixesha elide lubalulekile njengakwimizi-mveliso yeoli, isinyithi, igesi kunye nemibhobho yamanzi. Nangona kunjalo, iimfuno zokusebenza ze-FBE powder coatings zingumngeni ngenxa yoxinaniso oluphezulu lwe-cross-linking. Ubuqhophololo bendalo botyabeka olunyangekileyo ngomnye weyona miqobo iphambili ethintela usetyenziso olubanzi lweeepoxies.Funda ngokugqithisileyo …
Intshayelelo ye-Fusion eboshiweyo yomgubo we-epoxy
Utyabeka lwe-epoxy oludityanisiweyo lwe-epoxy, olukwabizwa ngokuba yi-fusion-bond epoxy powder ukutyabeka nedla ngokubizwa ngokuba yi-FBE yokugquma, lutyatyazo olusekwe kwi-epoxy olusetyenziswa kakhulu ukukhusela umbhobho wentsimbi osetyenziswa kulwakhiwo lwemibhobho, imivalo yokuqinisa ikhonkrithi (rebar) nakwi- Iintlobo ngeentlobo zoqhagamshelo lwemibhobho, iivalvu njalo njalo ukusuka kumhlwa. Iingubo ze-FBE ziingubo ze-polymer ze-thermoset. Zingena phantsi kodidi 'lweengubo zokukhusela' kwiipeyinti kunye ne-nomenclature yokwambathisa. Igama elithi 'fusion-bond epoxy' kungenxa yeresin cross-linking kunyeFunda ngokugqithisileyo …
