Khoom Tooj Tuag. Ntawm no yog Qhov Hloov.
Architects tseem qhia cov khoom tooj liab lossis tuab steel panels rau kab hlau rhuav phab ntsa. Qhov ntawd yog ib qho yuam kev. Lub teeb yuag tooj liab steel composite vaj huam sib luag rau ntaub thaiv phab ntsa xa tib qhov tsos thiab corrosion kuj ntawm ib nrab ntawm qhov hnyav. Tus qauv load txo ntawm 40% rau 60% yog niaj hnub. Tsis muaj kev cuam tshuam txog hluav taws kev nyab xeeb lossis kev ua neej ntev. Kev lag luam tau qeeb los txais yuav qhov no vim tias cov cwj pwm qub tuag nyuaj. Tab sis physics thiab economics tsis dag.
Kab lus no nteg tawm raws nraim yog vim li cas koj yuav tsum hloov, yuav ua li cas cov panels ua, thiab cov ntaub ntawv ua haujlwm dab tsi koj xav tau piv. Tsis muaj fluff. Tsis muaj kev lag luam. Tsuas yog logic.
Khoom siv: Ob Hlau, Ib Lub Hom Phiaj
Lub teeb hnyav tooj liab hlau vaj huam sib luag tsis yog sib tov. Nws yog metallurgical daim ntawv cog lus ntawm lub ntsej muag tooj liab nyias thiab cov tub ntxhais hlau. Cov txheej tooj liab yog feem ntau 0.3 mm rau 1.0 mm tuab. Cov tub ntxhais hlau yog galvanized lossis stainless hlau, 0.5 mm rau 2.0 mm. Tag nrho thickness nyob rau hauv 3 mm. Qhov kev sib xyaw ua ke no muab koj cov tooj liab patina rau sab nraud thiab lub zog ntawm cov hlau nyob rau sab hauv.
Cov khoom tseem ceeb:
- Copper txheej muab corrosion kuj thiab ntuj aging patina
- Cov tub ntxhais hlau muab kev nruj thiab dent kuj
- Composite ntom ntom yog 40% qis dua cov tooj liab ntawm tib lub thickness
- Thermal expansion coefficient ntawm daim ntawv cog lus yog engineered kom phim ob qho tib si hlau
Kev tsim khoom: Explosion Bonding vs. Roll Bonding – Uas Yeej?
Ob txoj kev yeej. Explosion bonding siv tswj detonation rau weld tooj liab rau hlau. Roll bonding siv cua sov thiab siab nyob rau hauv ib tug yob zeb. Rau curtain phab ntsa panels, Roll bonding yog superior. Vim li cas? Nws ua thinner, ntau cov nplooj ntawv zoo sib xws nrog nruj dua tolerances. Kev sib tsoo tawg yog qhov zoo dua rau cov phaj tuab (dhau 6 mm) tab sis tsim nto ripples uas yuav tsum tau ntxiv xov. Rau lub teeb yuag panels hauv qab 3 mm, yob kev sib txuas yog sai dua thiab pheej yig dua. Daim ntawv cog lus muaj zog tshaj 200 MPa hauv ob qhov xwm txheej. Delamination tsis yog ib qho kev txhawj xeeb yog tias cov txheej txheem raug lees paub.
