Chitsulo Chomera Chemical Chemical

Steel Structure Chemical Plant ndi malo omanga omwe ali pachiwopsezo chachikulu omwe amayenera kutsatira malamulo okhwima komanso zofunikira zachitetezo. Monga gulu lotsogola pantchito yomangamanga m'chigawo cha Shandong, EIHE Steel Structure (EHSS) imayendetsa mosamalitsa chitetezo ndi miyezo yopangira, ndipo ndiwe wodalirika waukadaulo wapamwamba wopanga zitsulo.

Tumizani Kufunsira

Mafotokozedwe Akatundu

Steel Structure Chemical Plant ndi nyumba yapadera yomwe imayenera kutsatira zofunikira zachitetezo chapadera monga kukana dzimbiri, kuteteza kuphulika, kuteteza moto komanso kupewa kuphulika. Popanga zinthu zotere, fakitale yathu imayendetsa mosamalitsa mtundu wazinthu kuyambira pakusankha zinthu mpaka kupanga ndi kukhazikitsa, kuwonetsetsa kutumizidwa mwachangu komanso kotetezeka kwazinthuzo.

● Kusankha Zinthu Zofunika Kwambiri

Timagwiritsa ntchito chitsulo champhamvu kwambiri chophatikizana ndi matekinoloje odana ndi dzimbiri kuti tiwonjezere moyo wautumiki wa zinthu zathu.

✔ Zida Zoyambira:

- Pamalo wamba: Q235B kapena Q355B chitsulo chopangidwa ndi kaboni chimasankhidwa.

- Pamalo owononga kwambiri: zitsulo zanyengo monga Q355NH ndizokonda.

- Pazigawo zomwe zimalumikizana mwachindunji ndi zowononga: 316L kapena 304 zitsulo zosapanga dzimbiri zimagwiritsidwa ntchito.

✔ Mapangidwe a Gawo:

- Magawo otsekedwa kapena magawo olimba a ukonde amayikidwa patsogolo, ndikuwongolera mosamalitsa makulidwe ochepa a khoma.

- Zigawo zazitsulo zozizira zokhala ndi mipanda yopyapyala ndizoletsedwa m'magawo oyamba onyamula katundu.

✔ Anti-corrosion zokutira:

- Dongosolo la malaya atatu limayikidwa: epoxy zinc-rich primer, epoxy micaceous iron oxide intermediate coat, ndi polyurethane kapena fluorocarbon topcoat.

- Makulidwe onse owuma a filimu azikhala osachepera 200 μm.

● Njira Yopangira

Chitsulo Chomera Chemical Zomera zimatenga njira zolimbikitsira kupanga kuti zitsimikizire mtundu wazinthu zomwe zimaperekedwa.
