Kusukela ngomhla zingama-31 kuNdasa kuya kumhla zi-2 kuMbasa wezi-2023, "iNgqungquthela Kazwelonke Yezemfundo Yebhuloho Yangowezi-2022 ye-China Highway Society Branch of Bridge and Structural Engineering kanye Nomhlangano Wesibili Womkhandlu Wesibili Wegatsha" yabanjwa ngempumelelo e-Zhuhai, esifundazweni sase-Guangdong.
Le ngqungquthela ihlelwe ngokuhlanganyela iBridge and Structural Engineering Branch ye-China Highway Society, i-Guangdong Transportation Group Co, i-Guangdong Provincial Highway Society kanye ne-Guangdong Provincial Highway Construction Co. Indikimba yengqungquthela ibisithi “Ukwakhiwa Okukhaliphile Nokugcinwa Kwamabhuloho Amade Nokuphathwa Kwesimanjemanje. ", futhi wamema izivakashi eziningi, ochwepheshe bezimboni zamabhuloho, abakhiqizi bemishini, nababhali bamaphepha bezazi.
Le ngqungquthela ikhombise impumelelo enkulu yokwakhiwa kwamabhuloho e-China eminyakeni yakamuva.I-ZINDN imenywe abagqugquzeli bengqungquthela ukuthi ilethe imikhiqizo emibili yezobuchwepheshe, i-ZINDN Cold Galvanizing Compound kanye ne-Graphene Zinc Coating, ukuze ixoxisane futhi ixhumane nabahlanganyeli bengqungquthela mayelana nendaba yokuvikela ukugqwala kwebhuloho.
I-ZINDN Cold Galvanizing Compound
1. Ukuvikela ukugqwala okuhlala isikhathi eside
Ukuvikelwa okuphindwe kabili kokuvikelwa kwe-cathodic + ukuvikelwa kwesithiyo, ukumelana nesifutho sikasawoti kuze kufike ngaphezu kuka-5000h, kufinyelela kalula iminyaka engaphezu kwengu-25 yokulwa nokugqwala.
2. Ukunamathela okuqinile
Ubuchwepheshe be-agent ehlanganisiwe obuthuthukisiwe buxazulula inkinga yokunamathela kokuqukethwe kwe-zinc powder ephezulu (ngaphezu kwama-96% we-zinc yefilimu eyomile).Ingxenye engu-4% yenqwaba ye-ejenti yokuhlanganisa ingabopha ngokuqinile izikhathi ezingu-24 isisindo sayo se-zinc powder futhi yenze isibopho se-zinc powder ne-substrate, ngamandla okunamathela angu-5-10 MPa.
3. Ukuhambisana okuhle
Ingasetshenziswa njengesendlalelo esisodwa noma njengesistimu yezingqimba ezimbili noma ezintathu ezine-sealer, ijazi eliphezulu, i-zinc-aluminium coating, njll., ukuhlangabezana nezidingo zamakhasimende zokuvikela okuhlala isikhathi eside nokuhlobisa okuhle.
4. Ukufakwa kwe-weld seam akuqhekeki futhi akuwi
Rarulula iphuzu lobuhlungu bemboni ukuthi ukugqoka okubandayo okubandayo kulula ukuqhekeka nokuwa emthungo we-weld, futhi ikhwalithi yokwakha iqinisekisiwe.
5. Ukwakhiwa okulula
Ingxenye eyodwa, ingagoqwa, ibhulashwe, ifuthwe ngomoya noma ifuthwe ngaphandle komoya.Akukho ukucwila, akukho ukuvinjwa kwesibhamu noma ukuvimbela iphampu, ukwakha okulula.
6. Ukusebenza kwezindleko eziphezulu
Uma iqhathaniswa ne-hot-dip galvanizing kanye ne-thermal sprayed Zinc, ihambisana nemvelo, ibiza kancane, futhi kulula ukuyinakekela.Uma kuqhathaniswa nopende onothile nge-epoxy zinc, isikhawu phakathi kokulungisa nokunameka side, futhi wonke umjikelezo wempilo wesakhiwo sensimbi unezindleko eziphansi zokunqanda ukubola.
