Kev ua kom zoo ntawm microporous cov qauv thiab txhim kho ntawm kev co kom txo kev txo qis ntawm cov xov xwm khiav
Cov ntaub ntawv tsoos roj hmab tsoos muaj 2.5db kev co kom txo qis thiab 1.2g ballast nrawm. Yuav ua li cas thiaj zoo rau cov qauv microcellular, thiab cov qauv yog dab tsi?
Discing tsis zoo ua rau muaj kev co kom zoo. Kev ua kom zoo: ① microcellular EPDM (0.1-0.3mm Pores, 40% nthuav dav); ② 12 hli thickness + 1 hli pob; ③ 15% Carbon Dub. Cov Qauv: Loj dua lossis sib npaug ntawm 6DB txo qis, tsawg dua lossis sib npaug nrog 1 hli compression / xyoo, haum 30t}% qis ceev ceev.
Microcellular tev muaj 4dB txo qis tom qab 1 xyoo hauv ph =4.5 av. Yuav ua li cas thiaj zoo corrosion tsis kam, thiab dab tsi yog qhov yuav tsum tau ua?
Acid Erodes Roj Hmab Chains. Optimization: ① 10μm fluorocarbon txheej; ② 5% antioxidant; ③ Coob ntug. Yuav tsum muaj: tsawg dua los yog sib npaug / sib npaug / sib npaug, tsis muaj xeb, tsawg dua lossis sib npaug ntawm 5 lub neej.
Dab tsi yog kev sib tw / durabilation xeem / qauv kev xeem / qauv rau microcellular ticts, thiab yuav ua li cas txhawm rau txhim kho Uneven pores (0.2 hli sib txawv)?
Kev ntsuam xyuas pov thawj cov nyhuv thiab sib thooj. Cov hau kev: ① kev txo kev txo qis / kev ntsuas kom nrawm; ② corrosion kev ntsuas; ③ Pore soj ntsuam. Cov Qauv: Loj dua los yog sib npaug rau 6DB txo qis, tsawg dua lossis sib npaug rau 0.1mm pore dismiation. Kev Txhim Kho: ① kho cov npuas ncauj / nplawm; ② Online Pore soj ntsuam; ③ Pwm Tso Kom Zoo Dua.
Dab tsi yog qhov ntsuas sib txawv rau ballast / backastless / slab khiav txaj, thiab muaj dab tsi tshwm sim nrog mismatch?
Qhov sib txawv: ① ballast: 45% nthuav dav, ntug dej 65a; ② Ballastless: 35% nthuav dav, ntug dej 70a; ③ Slab: 40% nthuav dav, Ntug Dej 68a. Lub hauv paus: Taug qab txhav txhav. Miscatch: high -} Kev nthuav dav ncoo rau ballastless: 2 hli compression / xyoo, 12% nce kev sib txawv.
Yuav ua li cas thiaj ua kom zoo Pad - kev tsheb ciav hlau haum, thiab ua li cas nrog kev sib txuam tsis zoo?
Sib piv ua kom sawv daws kev sib tw vibration kis. Kev Ntsuas: ① 2mm saj txheej txheem (haum ± 0.5mm kev sib tw); ② Kev sib tsoo kev sib tsoo (ntau dua lossis sib npaug ntawm 90% haum); ③ Coupling Tus Neeg Sawv Cev. Cov Qauv: Loj dua los yog sib npaug rau 95% kev sib xws, tsawg dua lossis sib luag rau 0.5DB sib txawv. Kev sib txuam tsis zoo: Kev ua haujlwm hauv zos mus txog 0.9g, tsis sib luag.
