Tilmaamayaasha aasaasiga ah ee calaamadeynta guluusyada muraayadaha indhaha iyo codsiyadooda badbaadada wadooyinka
Waqtiga siideynta:2025-09-04
Geedka dhalada ee galka ayaa ah qaybaha lagama maarmaanka u ah calaamadaha wadooyinka, kor u qaadista aragtida habeenkii ee habeenka dib-u-soo-celinta gawaarida gawaarida. Wax qabadkooda waxay ku xidhaan saddex tilmaamayaal asaas ah
Tusmada firfircoonaanta (RI): waxay go'aamisaa hufnaanta iftiinka iftiinka iftiinka. Beerta caadiga ah (RI 1.5) waxay bixisaa dhalaalkiisu yahay 150-450 MCD-da 1. Ride-river-ka
SPHERICITITITITITITITITITITITITITITITITITITITITITITITITITITITITITITE: Beeras leh ≥80% lafdhabarta hubinta khafiifka ugu habboon ee diiradda la saarayo oo yareeya xirashada farsamada. Is-hoosaysiinta hoose waxay keentaa milicsiga aan sinnayn oo dardar geliya fallaaraha calaamadaynta xaalufinta.
Cabbirka walxaha Qaybinta labiska ayaa ka hortagaya isku-darka isku-darka ama caymiska aan ku filnayn.
Codsiyada amniga wadada:
Geedka dhalada waxaa lagu dhejiyaa heerkul, laba-qaybood, ama calaamadaha biyaha ku saleysan. Waxaa lagu dabaqay iyada oo loo marayo pre-isku-darka (20% mugga) ama dusha sare) ama dusha sare (0.5 kg / m²), waxay ilaaliyaan minka 3-8 sano. Bead-riws (≥1.7) Waxay muhiim u yihiin aagagga roobka-u nugul iyo nidaamyada taraafikada ee caqliga leh (ay u saamaxeyso Adas iyo gawaarida is-madaxbannaan si loo ogaado haadka xaaladaha xun.
Heerarka & U hoggaansanaanta:
Tayada la jaan qaada GB / T24722-2020 (Shiinaha) iyo EN1423 (EU), Imtixaannada waajibka ah ee loogu talagalay caabbinta baabi'inta, xasilloonida uv, iyo cimri-galka deegaanka. Alaabada la xaqiijiyay (E.G., ISO9001, CCPC) waxay xaqiijisaa muddada dheer oo yareynaysa soo celinta soo celinta inta jeer ee 40%.
Asal ahaan, galka galaaska ayaa loo beddelay calaamadaha aan tooska ahayn hagida amniga firfircoon, isu dheellitirka dhaanta bilowga ah ee leh waxqabadka muddada-dheer iyada oo loo marayo injineeriyada indhaha iyo farsamada.
