Amacandelo amabini epoxy ephakathi ipeyinti yepolyamide ephilisiwe, isithintelo esilungileyo kunye nepropathi ye-anticorrosion, ikwazi ukumelana namanzi, ioyile, iikhemikhali, ipropathi ende yokwaleka.
Iimbonakalo
Ngenxa yobuninzi be-mica iron oxide edibeneyo, yenza "i-labyrinth" kwifilimu yepeyinti, ngoko ifilimu yepeyinti inomqobo obalaseleyo kunye nokumelana nokubola.
Ukuchasana okugqwesileyo kumoya wemichiza, umoya weshishini kunye nomoya waselwandle, kwaye unokumelana kakuhle namanzi olwandle, ityuwa, i-asidi ebuthathaka kunye ne-alkali ebuthathaka.Amaxesha amade okubuyisela.
Usetyenziso olucetyiswayo
I-1.Isetyenziswe njengoluhlu oluphakathi kunye nokutywinwa kweepeyinti ezichasene ne-rust ezifana ne-epoxy zinc-rich primer kunye ne-inorganic zinc-rich primer ukuphucula umqobo kunye neepropati ezikhuselayo zengubo yonke.
2.Isetyenziswe njenge-antirust primer yezakhiwo zetsimbi.
I-3.Isetyenziswe njenge-interlayer kwinkqubo yokugubungela ukukhusela ikhonkrithi.
I-4.Isetyenziswe njenge-topcoat yokulungisa phezu kweengubo ezindala apho ukuhambelana kuvumela.
Imiyalelo yesicelo
Intsimbi:ukuqhushumba kucocwe ukuya ku-Sa2.5 (ISO8501-1) okanye ubuncinane be-SSPC SP-6, iprofayili yokuqhushumba Rz30μm~75μm (ISO8503-1) okanye isixhobo samandla sicocwe ukuya kubuncinane be-ISO-St3.0/SSPC SP3
Isiseko seworkshop esakhiwe ngaphambili:I-Welds, i-firework calibration kunye nomonakalo kufuneka iqhume icocwe kwi-Sa2.5 (ISO8501-1), okanye isixhobo samandla sicocwe ukuya kwi-St3.0.
Umphezulu one-primer eqatywe:Coca kwaye uyomile ngaphandle kweetyuwa ze-zinc kunye nokungcola.
Gqibezela:Susa ngokucokisekileyo igrisi kumphezulu kwaye ucoce ityuwa kunye nobunye ukungcola.Kungcono ukusebenzisa ukucoca ukuqhuma ukususa umhlwa kunye nezinye izinto ezikhululekile.Sebenzisa isixhobo samandla ukupolisha indawo yomhlwa, kwaye uphinde ujike lo mbandela.
Iyasebenza kwaye iyanyangwa
1.Iqondo lobushushu lokusingqongileyo kufuneka libe ukusuka ku-5℃ ukuya kwi-35℃, ukufuma komoya okuhambelanayo akufuneki kube ngaphezu kwe-80%.
2.Iqondo lobushushu le-substrate ngexesha lokufakwa kunye nokunyanga kufuneka libe yi-3℃ ngaphezu kwendawo yombethe.
3.Ukusebenza kwangaphandle akuvumelekanga kwimozulu embi njengemvula, inkungu, ikhephu, umoya onamandla kunye nothuli olunzima.
Usetyenziso
● Ubushushu bemo engqongileyo kufuneka bube ukusuka kwi-5℃ ukuya kwi-38℃, ukufuma komoya okunxulumeneyo akufunekanga kube ngaphezu kwe-85%.
● Ubushushu be-substrate ngexesha lokufakwa kunye nokunyanga kufuneka lube yi-3℃ ngaphezu kwendawo yombethe.
● Ukusetyenziswa kwangaphandle akuvumelekanga kwimozulu embi njengemvula, inkungu, ikhephu, umoya onamandla kunye nothuli olunzima.
● Xa i-Ambient iqondo lobushushu li--5 ~ 5℃, kufuneka kusetyenziswe iimveliso zokunyanga ubushushu obuphantsi okanye amanye amanyathelo kufuneka athathwe ukuqinisekisa ukunyangwa okuqhelekileyo kwefilimu yepeyinti.
