Perforated steel sawb PE yeeb nkab Rau dej
Daim ntawv thov
Perforated steel strip polyethylene composite yeeb nkab yog ua los ntawm txias-dov strip steel thiab thermoplastics raws li raw cov ntaub ntawv, thiab ntxeem tau nyias-walled steel kav tsim los ntawm argon arc taub qab vuam los yog plasma kauv vuam yog siv los ua reinforcements. Cov txheej txheej sab nrauv thiab sab hauv yog ob sab sib xyaw thermoplastics. Ib hom tshiab ntawm cov yeeb nkab siab, Vim tias qhov ntxeem tau nyias-walled steel yeeb nkab reinforcement yog qhwv hauv cov thermoplastic tsis tu ncua, cov yeeb nkab sib xyaw no tsis tsuas yog kov yeej cov kev ua tsis zoo ntawm cov kav hlau thiab cov kav dej yas, tab sis kuj muaj cov rigidity ntawm cov kav hlau thiab cov corrosion. tsis kam ntawm cov kav dej yas. Nws yog kev daws teeb meem rau roj av thiab tshuaj lom neeg kev lag luam. Nws yog ib qho kev xav tau ceev ceev ntawm cov kav dej loj thiab nruab nrab txoj kab uas hla hauv cov chaw muag tshuaj, khoom noj, mining, roj thiab lwm yam kev lag luam. Nws kuj yog ib qho kev hloov kho thev naus laus zis los daws cov kav dej loj ntawm kev tsim kho thiab hauv nroog dej. Nws yog ib hom tshiab ntawm cov kav dej sib txuas hauv 21stxyoo pua.
Nta
Siab zog thiab qis linear expansion.
Vim lub zog ntawm cov ncej steel, lub perforated steel strip yas puas yeeb nkab muaj zog dua, siab rigidity thiab cuam tshuam tsis kam tshaj cov yeeb nkab yas. Nyob rau tib lub sijhawm, kev txwv tsis pub siv cov ncej steel kuj ua rau cov perforated steel strip yas puas yeeb nkab muaj kab qis zoo ib yam li cov yeeb nkab steel. Expansion coefficient thiab сгеер kuj.
Corrosion thiab hnav tsis kam.
Cov khoom siv high-density polyethylene xaiv rau perforated steel sawb yas puas yeeb nkab yog crystalline non-polar polymer cov khoom nrog cov tshuaj ruaj khov, tsis kam mus rau feem ntau cov kua qaub, alkali ntsev thiab organic media, thiab electrochemical corrosion. Kev sib tsoo kev ua tau zoo yog 5 npaug siab dua li cov kav hlau.
Technical Parameters
Cov khoom no siv tshwj xeeb polyethylene cob, thiab nws lub cev thiab txhua yam khoom ua tau raws li Ministry ntawm kev tsim qauv CJ / T181-2003 thiab cov qauv kev lag luam tshuaj HG / T3706-2014.

| Lus Cim: Lub nominal siab ntawm cov yeeb nkab sib xyaw yog qhov siab tshaj plaws tso cai rau cov yeeb nkab thauj dej ntawm 20 ° C. Yog tias qhov kub thiab txias hloov, lub siab ua haujlwm yuav tsum raug kho raws li qhov kub siab coefficient ntawm cov khoom sib txawv. S tus nqi: qhov kev ncua deb ntawm sab nraud ntawm qhov kev txhawb nqa mus rau sab nrauv ntawm cov yeeb nkab. | |||||
