Tsis ntev los no, cov ntaub ntawv txheem ntawm "JINBIAOTechnical Requirements for Metal Sound Barriers" tau tsim los ntawm Hengshui City Market Supervision Bureau, Hebei Jinbiao Building Materials Technology Co., Ltd. thiab Hebei Wire Mesh Product Quality Supervision and Inspection Center tau pom zoo, Lub Yim Hli 2019 Kev siv pib ntawm 1st.
Cov qauv no suav nrog cov ntsiab lus dav dav thiab cov ntsiab lus ntawm cov hlau tsis muaj suab nrov, cov lus qhia tshwj xeeb, cov kev xav tau, kev sim thiab lwm yam.Nws yog qhov tsim nyog rau cov suab nrov hlau siv los txo qhov cuam tshuam ntawm lub suab nrov ntawm qhov chaw acoustic ntawm qhov chaw rhiab thaum lub suab nrov tawm.Nws feem ntau yog tsim los ntawm kev tshuaj ntsuam lub cev, txhawb cov tswv cuab thiab cov khoom sib txuas tsim nyog.
Cov ntaub ntawv hauv qab no yog qhov tseem ceeb rau kev siv daim ntawv no.Rau cov ntawv sau hnub tim, tsuas yog hnub tim version siv rau daim ntawv no.Rau cov ntaub ntawv tsis raug lees paub, tsab ntawv tshaj tawm tshiab (nrog rau txhua qhov kev hloov kho) siv rau daim ntawv no.

Tus txheej txheem yog raws li kev npaj txaus, paub tab technology thiab siab heev, tag nrho cov kev qhia yog scientific thiab tsim nyog, kev ntsuas yog dav thiab tshwj xeeb, thiab kev kawm theem yog ua nyob rau hauv domestic.
Cov hlau tsis muaj suab nrov tau dhau los ua lub suab thiab suab nrov txo qhov chaw txhawb nqa thiab siv hauv thaj tsam Beijing-Tianjin-Hebei.Yav dhau los, tsis muaj tus qauv meej meej rau cov lus qhia tshwj xeeb ntawm lub suab nrov ntawm cov hlau, thiab tsis muaj txoj hauv kev los ntsuas qhov zoo ntawm cov khoom.Cov lus qhia tshwj xeeb ntawm cov hlau suab barrier tau teev nyob rau hauv daim ntawv no.parameter:
Kev siv cov ntaub ntawv tus qauv no muab lub hauv paus rau kev tswj hwm thiab txhim kho cov khoom zoo ntawm cov khoom siv hlau suab nrov hauv cheeb tsam Beijing-Tianjin-Hebei.
Raws li cov ntawv tshaj tawm hauv zos tau tshaj tawm los ntawm lub xeev lub chaw lis haujlwm, rau tus qauv ntawm Hengshui City tau raug pom zoo raws li cov qauv hauv nroog ntawm Hebei Xeev, ntawm 5 yog cov qauv kev lag luam hlau, ntxiv rau "Cov Kev Xav Tau Ntawm Cov Hlau Suab Barriers" tau piav qhia. saum toj no, Cov khoom yog "Cov Kev Xav Tau Rau Cov Hlau Hlau (Rebar) Welded Wire Mesh", "Cov Kev Xav Tau Zoo rau Cov Hlau Hlau Txuas Paj Ntsig (Rhombus Net)," Cov Txheej Txheem Txheej Txheem rau Aluminium Phaj Tensile Decoration Net", thiab " General Technical Requirements for Aluminium Window Gap ".Nws ntseeg tau tias kev ua raws li cov qauv no yuav txhawb kev lag luam-hais lus lub zog ntawm cov tuam txhab xaim mesh thiab nce lawv cov kev lag luam.
