Kubva Kurume 31 kusvika Kubvumbi 2, 2023, "2022 National Bridge Academic Conference yeChina Highway Society Branch yeBridge and Structural Engineering uye yeNinth Second Council Meeting yeBazi" yakaitwa zvakabudirira muZhuhai, Guangdong Province.
Musangano uyu wakarongwa pamwe chete neBazi reBridge and Structural Engineering reChina Highway Society, Guangdong Transportation Group Co, Guangdong Provincial Highway Society neGuangdong Provincial Highway Construction Co. ", uye vakakoka vaenzi vazhinji, nyanzvi dzeindasitiri yemabhiriji, vagadziri vemidziyo, uye vanyori vemapepa enyanzvi.
Musangano uyu wakaratidza kubudirira kukuru kwekuvaka mabhiriji kuChina mumakore apfuura.ZINDN yakakokwa nevarongi vemusangano kuti vauye nezvigadzirwa zviviri zveunyanzvi, ZINDN Cold Galvanizing Compound uye Graphene Zinc Coating, kuti vakurukure uye vataurirane nevatori vemusangano pamusoro penyaya yekudzivirirwa kwebhiriji.
ZINDN Cold Galvanizing Compound
1. Kuchengetedza kwekugara kwenguva refu
Kaviri kudzivirira mhedzisiro ye cathodic dziviriro + chipingamupinyi chekudzivirira, munyu pfapfaidzo kuramba kusvika kupfuura 5000h, kuwana nyore kupfuura makore makumi maviri neshanu-yakareba-anti-corrosion.
2. Kunamatira kwakasimba
Iyo yakanyatsogadzirwa fusion agent tekinoroji inogadzirisa dambudziko rekunamatira repamusoro zinc poda yemukati (inopfuura 96% yakaoma firimu zinc).4% chikamu chemushonga wefusion agent inogona kusungirira zvakasimba ka24 huremu hwayo hwezinc poda uye kuita zinc poda bond ne substrate, ine simba rekunamatira re5-10 MPa.
3. Kugarisana kwakanaka
Inogona kushandiswa sechinhu chimwe chete kana semaviri- kana matatu-layer system ine sealer, top coat, zinc-aluminium coating, nezvimwewo, kusangana nevatengi zvinodiwa zvekuchengetedza kwenguva refu uye kushongedza kwakanaka.
4. Iyo yekupfeka ye weld seam haina kuputika uye haina kudonha
Gadzirisa marwadzo eindastiri iyo inotonhora yekuisa galvanizing coating iri nyore kutsemuka uye kudonha pamushoni we weld, uye mhando yekuvaka inovimbiswa.
5. Kuvaka kwakanaka
Chikamu chimwe chete, chinogona kukungurutswa, kukweshwa, kupfapfaidzwa nemhepo kana kupfapfaidzwa pasina mhepo.Hapana kunyura, hapana kuvharira pfuti kana kuvharira pombi, zviri nyore kugadzira.
6. Kushanda kwepamusoro-soro
Kana ichienzaniswa neinopisa-dip galvanizing uye yekupisa yakapfapfaidzwa Zinc, inoenderana nenharaunda, yakaderera mutengo, uye iri nyore kuchengetedza.Kana ichienzaniswa ne epoxy zinc-rich pendi, iyo nguva pakati pekugadzirisa uye kudzoreredza yakareba, uye hupenyu hwese hwechimiro chesimbi ine yakaderera anti-corrosion mutengo.

Zvakanakira ZINDN High Performance Graphene Zinc Coating
No.1: Surface resistivity ≤ 10⁶ Ω;
Neutral munyu pfapfaidzo kuramba bvunzo ≥ 4500h;
Inogona kupa kuchengetedzwa kwekugara kwenguva refu munzvimbo dzakasiyana-siyana dzinoparadza;
No.2: VOCs content: ≤340g/L;
Sangana nezvinodiwa zveyakakodzera yenyika zviyero, girinhi uye kuchengetedzwa kwezvakatipoteredza;
No.3: High coating rate, 60μm yakaoma firimu ukobvu theoretical coating rate inosvika 4.7m²/kg, ichichengetedza kupfuura 15% dosage pane 80% zinc-ine epoxy zinc-rich pendi;
Nha.4: Kushandiswa kwehushamwari, kutsigirwa kwakakura, uye kunamatira kwepamusoro uye kwakagadzikana.
