Kuyambira pa Marichi 31 mpaka Epulo 2, 2023, "2022 National Bridge Academic Conference of China Highway Society Branch of Bridge and Structural Engineering ndi Msonkhano Wachisanu ndi chinayi wa Nthambi ya Nthambi" idachitika bwino ku Zhuhai, Province la Guangdong.
Msonkhanowu unakonzedwa pamodzi ndi nthambi ya Bridge and Structural Engineering ya China Highway Society, Guangdong Transportation Group Co, Guangdong Provincial Highway Society ndi Guangdong Provincial Highway Construction Co. Mutu wa msonkhanowu unali "Kumanga Mwanzeru ndi Kusamalira Milatho Yaitali ndi Kasamalidwe Kamakono ", ndikuitana alendo ambiri, akatswiri amakampani a mlatho, opanga zida, komanso olemba mapepala aukadaulo.
Msonkhanowu udawonetsa zopambana zomanga mlatho ku China m'zaka zaposachedwa.ZINDN inaitanidwa ndi okonza msonkhano kuti abweretse mankhwala awiri aukadaulo, ZINDN Cold Galvanizing Compound ndi Graphene Zinc Coating, kuti akambirane ndi kuyankhulana ndi ochita nawo msonkhano pa nkhani ya chitetezo cha mlatho.
ZINDN Cold Galvanizing Compound
1. Kuteteza dzimbiri kwanthawi yayitali
Kutetezedwa kawiri kwa chitetezo cha cathodic + chitetezo chotchinga, kukana kutsitsi kwa mchere mpaka kupitilira 5000h, kukwaniritsa mosavuta zaka zopitilira 25 zolimbana ndi dzimbiri.
2. Kumamatira mwamphamvu
Ukadaulo wopangidwa mwapadera wophatikizira amathetsa vuto lomatira la ufa wambiri wa zinc (wopitilira 96% ya zinki youma).4% misa kachigawo cha maphatikizidwe wothandizira amatha kulumikiza molimba nthawi 24 kulemera kwake kwa ufa wa zinki ndikupanga zinki ufa wolumikizana ndi gawo lapansi, ndi mphamvu yomatira ya 5-10 MPa.
3. Kugwirizana kwabwino
Ikhoza kugwiritsidwa ntchito ngati wosanjikiza umodzi kapena dongosolo la magawo awiri kapena atatu ndi sealer, malaya apamwamba, zokutira za zinc-aluminium, ndi zina zotero, kuti akwaniritse zosowa za makasitomala kuti atetezedwe kwa nthawi yaitali ndi kukongoletsa kokongola.
4. Chophimba cha weld seam sichimang'ambika ndipo sichigwa
Konzani zowawa zamakampani kuti zokutira zoziziritsa kuzizira ndizosavuta kung'ambika ndikugwa pamsoko wowotcherera, ndipo mtundu wa zomangamanga umatsimikizika.
5. Kumanga kosavuta
Chigawo chimodzi, chikhoza kukulungidwa, kupukutidwa, kupopera mpweya kapena kupopera popanda mpweya.Palibe kumira, palibe kutsekereza mfuti kapena kutsekereza pampu, yosavuta kupanga.
6. Kuchita zotsika mtengo
Poyerekeza ndi galvanizing ya dip-dip ndi Zinc yopopera mafuta, ndiyotetezeka ku chilengedwe, yotsika mtengo, komanso yosavuta kuyisamalira.Poyerekeza ndi utoto wochuluka wa epoxy zinc, nthawi yomwe ili pakati pa kukonza ndi kuyikanso ndi yayitali, ndipo moyo wonse wa chitsulo umakhala ndi mtengo wotsika wotsutsa dzimbiri.

Hong Kong-Zhuhai-Macao Bridge Gawo CB05
Ubwino wa ZINDN High Performance Graphene Zinc Coating
No.1: Kupambana kwapamwamba ≤ 10⁶ Ω;
Salowerera ndale mchere kutsitsi kukana mayeso ≥ 4500h;
Itha kupereka chitetezo chambiri kwanthawi yayitali m'malo owononga osiyanasiyana;
No.2: Zomwe zili mu VOC: ≤340g / L;
Kukwaniritsa zofunikira pamiyezo yoyenera yadziko, chitetezo chobiriwira ndi chilengedwe;
No.3: High ❖ kuyanika mlingo, 60μm youma filimu makulidwe Theoretical ❖ kuyanika mlingo kufika 4.7m²/kg, kupulumutsa oposa 15% mlingo kuposa 80% nthaka munali epoxy zinki wolemera utoto;
No.4: Kugwiritsa ntchito mwaubwenzi, chithandizo chokhwima, komanso kumamatira kwapamwamba komanso kokhazikika.
