Steel mesh skeleton polyethylene yeeb nkab
Daim ntawv thov
Hauv 20 xyoo dhau los, cov kav dej yas tshiab tau siv dav hauv cov nroog loj, roj av thiab cov chaw tsim hluav taws xob cog dej. Tshwj xeeb tshaj yog nrog kev txhim kho txuas ntxiv thiab kev tsim kho tshiab ntawm polyethylene polymerization thev naus laus zis, muaj ntau dua tensile zog polyethylene cov ntaub ntawv. Txhawm rau nthuav dav ntxiv ntawm cov qib siab rau cov kav dej yas, tshwj xeeb tshaj yog nyob rau xyoo tas los no, los ntawm kev tshawb fawb ntawm kev sib koom tes thev naus laus zis, steel-yas composite thev naus laus zis tau nthuav tawm tau ua tiav cov teeb meem ntawm cov kav dej polyethylene (PE) hauv cov ntsiab lus ntawm qib siab, tiv thaiv. corrosion, thiab zoo ncig txoj kab uas hla. Siv nyob rau hauv ntau yam ntawm cov dej siv thauj mus los.
Structure: Cov khoom no yog cov khoom siv ntxiv nrog cov txheej txheem tseem ceeb ntawm cov hlau tsis tu ncua uas muaj zog steel hlau tom qab txheej txheej, thiab cov kua nplaum tshwj xeeb kub-kua nplaum thiab cov yas tau muab tso rau hauv tag nrho cov yeeb nkab los ntawm extrusion molding txoj kev.
Nta
Economic kev ua tau zoo ntawm cov kav dej
Siv high-density polyethylene raws li cov ntaub ntawv hauv thiab txheej txheej, steel mesh skeleton polyethylene yas composite yeeb nkab muaj kev ua tau zoo ntawm cov khoom siv polyethylene yeeb nkab. Vim cov nyhuv ntawm cov pob txha steel, cov yeeb nkab sib xyaw ntawm tib theem siab muaj cov phab ntsa me me dua cov kav dej ntshiab. Kev ua haujlwm zoo агеа yog qhov loj dua, thiab qhov zoo corrosion kuj thiab hnav tsis kam ua kom ntseeg tau tias lub neej kev pabcuam ntawm cov yeeb nkab tuaj yeem ua tau li 50 xyoo, uas ua rau kev txhim kho kev lag luam ntawm cov kav dej.
Ntxiv dag zog rau lub cev pob txha kom ua kom cov kab nrib pleb zoo
Kev siv lub zog muaj zog steel mesh core txheej raws li lub cev pob txha txhawb nqa tau zoo inhibits cov kab nrib pleb thiab kev tawg sai sai ntawm cov ntaub ntawv polyethylene, thiab muaj zog compressive ntau dua (lub siab ntawm cov kav dej mus txog З.5МРа) thiab cov neeg txawv txawv сгеер tsis kam, Kev tiv thaiv siab dua, thiab nws cov ntsuas kev ua tau zoo yog cov kav dej polyethylene superiority.
