Imodi yokudibanisa yombhobho womlilo: intambo, i-groove, i-flange, njl. Umbhobho wensimbi wangaphakathi kunye wangaphandle we-epoxy wokukhusela umlilo yi-modified heavy-duty anti-corrosion epoxy resin powder, enokumelana nokugqwesa kweekhemikhali. Isombulula ngokusisiseko iingxaki ezininzi ezifana ne-rust corrosion kunye ne-internal wall scaling yeemveliso ezifanayo emva kokusetyenziswa kwexesha elide, ukwenzela ukuba kuthintelwe ukuvaleka kwangaphakathi okuchaphazela ukusetyenziswa, ukwenzela ukuba kuphuculwe kakhulu ubomi benkonzo yemibhobho ekhethekileyo yokulwa nomlilo. Ngenxa yokongezwa kwezixhobo ze-flame retardant kwizinto zokugubungela, ukuchasana nokushisa kwemveliso kuphuculwe xa kuthelekiswa nezinye iimveliso ezifanayo. Ngoko ke, akuyi kuchaphazela ukusetyenziswa xa ubushushu be-ambient bukhuphuka ngokukhawuleza. Ubomi benkonzo kunye nokusebenza kwemibhobho yomlilo efakwe ngaphakathi nangaphandle ingcono kakhulu kunemibhobho ye-galvanized. Umbala ubomvu.

Umzi-mveliso wethu ugxile ekuveliseni umbhobho womlilo, umbhobho wentsimbi, umbhobho wokugquma umgubo, umbhobho wokugquma umgubo kunye nombhobho wentsimbi we-intshi ezi-6. Isicelo: unikezelo lwamanzi omlilo, unikezelo lwerhasi kunye nenkqubo yemibhobho yothutho ephakathi kwegwebu. Umgangatho wemveliso udlula amasiko kwaye uphumelele iimvavanyo ezininzi ngaphambi kokushiya umzi-mveliso. Ukuthobela imigangatho yomgangatho wesizwe nehlabathi.

(1) Iimpawu eziphezulu zemishini. I-epoxy resin inobumbano olomeleleyo kunye nesakhiwo esixineneyo semolekyuli, ngoko ke iipropathi zayo zoomatshini ziphezulu kuneresin ze-thermosetting jikelele ezifana ne-phenolic resin kunye ne-polyester engafakwanga.

2 Inkqubo ye-epoxy resin yokunyanga iqulethe iqela le-epoxy, iqela le-hydroxyl, ibhondi ye-ether, ibhondi ye-amine, ibhondi ye-ester kunye namanye amaqela e-polar anomsebenzi omkhulu, onika i-epoxy ephilisa iimveliso ezinamathele ngokugqwesileyo kwisinyithi, i-ceramics, iglasi, ikhonkrithi, iinkuni kunye nezinye i-polar substrates.

(3) Ukuncipha okuncinci kokunyanga. Ngokubanzi 1% ~ 2%. Ngolunye lweentlobo kunye neyona nto incinci yokunyanga i-shrinkage phakathi kwe-resin thermosetting (i-phenolic resin yi-8% ~ 10%; i-resin ye-polyester engaxutywanga yi-4% ~ 6%; i-silicone resin yi-4% ~ 8%). I-coefficient yokwandiswa komgca incinci kakhulu, ngokubanzi 6 × 10-5/℃。 Ngoko ke, umthamo utshintsha kancinci emva kokunyanga.

(4) Ukusebenza kakuhle. I-epoxy resin ayivelisi i-volatiles ephantsi ye-molecular ngexesha lokunyanga, ngoko inokwakheka phantsi koxinzelelo oluphantsi okanye uxinzelelo loqhagamshelwano. Iyakwazi ukusebenzisana kunye neearhente ezahlukeneyo zokunyanga ukuvelisa iingubo ezihambelana nokusingqongileyo ezifana ne-solvent-free, high solid, i-powder coatings kunye neengubo ezisekelwe emanzini.

(5) Ukufakelwa kombane okugqwesileyo. I-Epoxy resin yintlaka ye-thermosetting eneempawu ezilungileyo ze-antistatic.

(6) Ukuzinza okulungileyo kunye nokuchasana kweekhemikhali. I-epoxy resin ngaphandle kwe-alkali, ityuwa kunye nezinye izinto ezingcolileyo akulula ukuwohloka. Ngethuba nje igcinwe ngokufanelekileyo (itywinwe, ikhululekile kumswakama kunye nokushisa okuphezulu), ixesha lokugcina li-1 ngonyaka. Emva komhla wokuphelelwa, ukuba uhlolo lufanelekile, lusenokusetyenziswa. Ikhompawundi yokunyanga i-epoxy inozinzo olugqwesileyo lweekhemikhali. Ukumelana ne-corrosion yayo kwi-alkali, i-asidi, ityuwa kunye neminye imithombo yeendaba ingcono kune-resin ye-polyester engaxutywanga, i-phenolic resin kunye nezinye i-thermosetting resins. Ke ngoko, i-epoxy resin isetyenziswa ngokubanzi njenge-anti-corrosion primer. Ngenxa yokuba i-epoxy resin enyangisiweyo inobume bothungelwano olunamacala amathathu kwaye inokuxhathisa ukufakwa kwe-oyile, isetyenziswa kakhulu kudonga lwangaphakathi lweetanki ze-oyile, iitanki zeoyile kunye neenqwelomoya.

(7) Ukumelana nobushushu bekhompawundi yokunyanga i-epoxy ngokuqhelekileyo ngama-80 ~ 100 ℃. Iindidi ezikwaziyo ukumelana nobushushu ze-epoxy resin zinokufikelela kuma-200 ℃ nangaphezulu.
