Classify Ductile Iron Products Based on Internal and External Coatings

Hlelaiimveliso zentsimbi ye-ductilengokusekwe kwiingubo zangaphakathi nangaphandle ngolu hlobo lulandelayo:

1. Ukwaleka okuqhelekileyo

Udaka lwesamente oluqhelekileyo lwe-portland luqatywe ngaphakathi ngelixa ipeyinti ye-zinc kunye ne-bituminous ipeyintwa ngaphandle.

2. Ingubo yangaphakathi yodaka lwesamente ye-sulfate

Isamente yeSulfate, ekwabizwa ngokuba yisamente ephezulu yesulfate-resistant, inokumelana ne-sulfate corrosion elungileyo kunye nesicelo esibanzi ekuthuthweni kwezinto eziyingozi kakhulu ezifana namanzi olwandle.

3.I-coating yangaphakathi yodaka lwesamente ye-aluminate

Umbhobho wentsimbi odityanisiweyo wombhobho wogutyulo ohambelana ne-ISO7186, EN598 kunye ne-GB/T26081 uqatywe ngesamente yealuminiyamu (ekwabizwa ngokuba yisamente yealumina ephezulu) ngaphakathi, ngesiphumo sokuxhathisa okugqwesileyo kukonakala kweekhemikhali kunye nokumelana ne-abrasive efaneleke ngakumbi. ukuthutha amanzi emvula, ugutyulo lwamanzi amdaka kunye neentlobo ezithile zamanzi ogutyulo lwemizi-mveliso.

I-4.Zinc-Aluminiyam yokugqoka

Umphandle wombhobho wentsimbi uqatywe ngeZinc-Aluminiyam yokwaleka (85%Zn+15%Al) enobunzima obungama-400g/m2, elungele umhlaba onokudleka okuphezulu.

5. Ingubo yangaphakathi ye-epoxy ceramic

Ingaphakathi le-epoxy ceramic yenziwe nge-epoxy resin, i-quartz powder kunye nezinye ezinobunzima befilimu eyomileyo engaphezulu kwe-1000μm, kunye nepropathi egqwesileyo yokumelana ne-corrosion yokufakelwa kombane yenza ukuba ibe yindawo ekhethiweyo ekuthuthweni kwelindle likamasipala, amanzi abuyiselweyo, njl.

6. I-epoxy resin yokutywina itywina

Umbhobho owenziwe nge-epoxy resin ukutywinwa kokutywina ulingana ne-samente yangaphakathi-efakwe ngaphakathi ngumaleko wokutywinwa kwe-epoxy resin, obunzima bayo bunqunywe ngokuhambelana neempawu ze-transmission medium, kwaye inokumelana okumangalisayo kwe-abrasive kunye nokuxhathisa ukubola.Ngombulelo kwincasa yetywina, ukuna kwemvula yezinto ezinobungozi kuxhathiswa ngokufanelekileyo, ngokuncomekayo ukuthintela ungcoliseko kwindawo yosasazo kwaye ifaneleke ngakumbi ukuhanjiswa ngokuthe ngqo kwamanzi okusela.

7. Ukwaleka kwepolyurethane

I-Polyurethane yokwaleka yenziwe ngezinto ezi-bi-component ze-polyurethane ukuya kwisikali, kwaye ayisebenzi nje kuphela njengento yangaphakathi yomgca wombhobho wentsimbi ephoswe ngamaqhuqhuva, kodwa njengokwaleka okunxulumene nokhukuliseko lwangaphandle.Ukwaleka kwePolyurethane kuneengenelo ezininzi ezifana nokumelana nokurhawuka okumangalisayo, ukumelana nokugqwesa okugqwesileyo, ukungagungqi, umphezulu ogudileyo, umlinganiselo omncinci wokuxhathisa, ikhompawundi eguquguqukayo embalwa, ipropathi ephawulekayo yokhuseleko lokusingqongileyo, njl njl. ukuthutha izinto ezonakalisayo okanye imimoya ekwimeko ephezulu yococeko, kubandakanywa amanzi athambileyo, ukukhutshwa kwetyuwa emanzini olwandle, amanzi amdaka kamasipala, amanzi amdaka avela kwimizi-mveliso, kunye nezinye;kwaye ezinye ezinobungqingqwa obungaphezulu kwe-700μm zisetyenziswa ikakhulu kwimeko-bume yomhlaba enokonakala okuqinileyo okufana nomhlaba ongcoliswe ngamanzi amdaka avela kwimizi-mveliso okanye ngokuxhathisa okuthile okuphantsi.
