Hlelaimikhiqizo ye-iron ductileokusekelwe ezimbotsheni zangaphakathi nezangaphandle kanje:
1. Ukugqoka okuvamile
Udaka olujwayelekile lukasimende lwe-portland lugcotshwa ngaphakathi kuyilapho upende we-zinc no-bituminous upendwe ngaphandle.
2. Ukufakwa kwangaphakathi kwe-sulfate simende udaka
Usimende we-sulfate, owaziwa nangokuthi usimende ongamelana ne-sulfate ephezulu, unokumelana nokugqwala okuhle kwe-sulfate kanye nokusebenza okubanzi ekuthutheni ezinye izinto ezigqwala kakhulu ezifana namanzi olwandle.
3.I-coating yangaphakathi ye-aluminatecement mortar
Ipayipi lensimbi elidonsayo lomzila wendle elihambisana ne-ISO7186, EN598 kanye ne-GB/T26081 limbozwe ngosimende we-alumina (owaziwa nangokuthi usimende we-alumina ephezulu) ngaphakathi, ngenxa yokumelana okuhle kakhulu nokugqwala kwamakhemikhali kanye nokumelana ne-abrasive efaneleka kakhulu ukuthutha amanzi emvula, indle yenhlanzeko kanye nezinhlobo ezithile zamanzi endle ezimbonini.
4.Zinc-Aluminium enamathela
Ingaphandle lepayipi lensimbi elibunjiwe limbozwe nge-Zinc-Aluminium coating (85%Zn+15%Al) enesisindo esingu-400g/m2, elungele inhlabathi enokubola okuphezulu.
5. Ukufakwa kwangaphakathi kwe-epoxy ceramic
Ingaphakathi le-epoxy ceramic lenziwe nge-epoxy resin, i-quartz powder kanye nezinye ezinogqinsi lwefilimu elomile elingaphezu kuka-1000μm, futhi indawo enhle kakhulu yokumelana nokugqwala kagesi yokuvikela imvelo yenza kube indawo ekhetheke kakhulu ekuthutheni indle kamasipala, amanzi abuyiselwe, njll.
6. I-epoxy resin seal coating
Ipayipi elicijile eline-epoxy resin sealing coating lilingana nolwelwesi olungaphakathi lukasimende olumbozwe ungqimba lwe-epoxy resin sealing, ugqinsi lwalo olunqunywa ngokuhambisana nezici ze-transmission medium, futhi linokumelana okubabazekayo okumangalisayo nokumelana nokugqwala.Ngenxa yokwembozwa kwezimpawu, imvula yezinto eziyingozi imelana ngokuphumelelayo, ngokutusekayo igwema ukungcoliswa kwendawo yokudlulisela futhi ifaneleka nakakhulu ukulethwa okuqondile kwamanzi okuphuza.
7. I-polyurethane enamathela
Ukufakwa kwe-polyurethane kwenziwa ngezinto ze-bi-component ze-polyurethane esikalini, futhi akusebenzi nje kuphela njengendawo yangaphakathi yepayipi yensimbi eyi-nodular cast iron, kodwa njengokunamathela kwangaphandle okumelana nokuguguleka.Ukufakwa kwe-polyurethane kunezinzuzo eziningi njengokumelana ne-abrasive emangalisayo, ukumelana nokugqwala okuhle kakhulu, ukungagcwali, indawo ebushelelezi, i-coefficient encane yokumelana, inhlanganisela yezinto eziphilayo ezimbalwa eziguquguqukayo, indawo ephawulekayo yokuvikela imvelo, njll. Ezinye izimbobo ze-polyurethane ezinogqinsi olungaphezu kuka-900μm zisetshenziswa kakhulu ukuthutha izinsiza ezonakalisayo noma imimoya esesimweni esiphezulu sokuhlanzeka, okuhlanganisa amanzi athambile, amanzi olwandle akhishwa usawoti emanzini, amanzi angcolile kamasipala, amanzi angcolile ezimbonini, nokunye;kanti amanye anogqinsi olungaphezu kuka-700μm asetshenziswa kakhulu endaweni ezungezile yomhlabathi enokugqwala okuqinile okufana nomhlabathi ongcoliswe amanzi angcolile ezimbonini noma ngokumelana okuthile okuphansi.
