Yog tias koj tau nyob hauv facade game ntev txaus, koj paub tias daim ntawv spec tsuas yog ib nrab ntawm zaj dab neeg. Lwm ib nrab plays tawm nyob rau hauv lub fabrication Rhiav, nyob rau hauv lub vuam torch, thiab thaum lub sij hawm lub caij ntuj sov thawj lub caij ntuj sov lub caij ntuj sov tom qab installation.
Peb tau siv kaum xyoo dhau los ntawmShandong Pinnjie Tshiab Khoom Co., Ltd. saib cov ntaub thaiv phab ntsa ua tiav los yog dawm raws li yuav luag tag nrho ntawm ob qhov sib txawv: txheej adhesion thiab tawm los sib xws. Peb tsis yog brokers xwb; peb khiav cov kab. Thiab tsis ntev los no, peb tau pom ib qho kev hloov pauv ntawm cov txheej txheem cov txheej txheem engineers tau thov thaum lawvhu rau peb.
Cov Qib Uas Uas Qhia Txog Peb Cov Ntawv Pov Thawj Mill
Cov neeg yuav khoom feem ntau nug rau "Q355B" lossis "ASTM A572 Gr.50" thiab hu nws ib hnub. Tab sis rau kab hlau rhuav phab ntsa mullions thiab transoms, lub substrate tsuas yog ib nrab ntawm kev sib ntaus sib tua. Raukub-dip galvanized (GI), peb thawb cov neeg siv khoom mus rau DX51D + Z nrog Z275 txheej yog tias lawv nyob ze ntawm ntug dej hiav txwv, lossis SGCC rau cov qauv hauv nroog.
Tab sis qhov kev ua si tiag - hloov pauv hauv 18 lub hlis dhau los?Zinc-Aluminium-Magnesium (ZAM)- tshwj xeeb S350GD+ZM. Kuv muaj ib tus neeg saib xyuas kev yuav khoom los ntawm Singapore-raws li tus neeg cog lus qhia rau kuv xyoo tas los tias nws cov peev nyiaj kho tau raug txiav los ntawm ze li 40% ntawm nws txoj haujlwm kawg tsuas yog vim nws tsis siv cov qauv GI ntawm kev txiav ntug. Cov magnesium nyob rau hauv ZAM txheej migrate mus rau cov laser - txiav ntug thiab tsim ib tug tiv thaiv hydroxide zaj duab xis. Nws tsis yog khawv koob; nws yog ib qho yooj yim electrochemistry, tab sis nws daws qhov "liab xeb creep" uas ruins facade aesthetics nyob rau hauv tsib xyoos.
Vuam Taub Hau: Yam Daim Ntawv Pov Thawj Zeb Tsis Qhia Koj
Ntawm no yog qhov uas feem ntau generic steel cia koj poob. Fabricators hu rau kuv ntxhov siab vim lawv tau txais porosity nyob rau hauv lub welds, los yog phem dua, lub HAZ (Huab cua cuam tshuam cheeb tsam) ua nkig.
Vim li cas peb cov khoom siv tus qauv AWS D1.1 vuam cov txheej txheem zoo dua? Nws nqis los rau tus nqi Carbon Equivalent (CEV). Peb khaws cov ntsiab lus carbon nruj me ntsis hauv qab 0.12% ntawm pebstructural txias- dov thiab galvanized puag stocks. Nyob rau hauv daim ntawv, uas suab boring. Hauv kev xyaum, nws txhais tau tias koj pab neeg tsis tas yuav fiddle nrog preheating los yog tom qab -weld qeeb txias rau thicknesses qis dua 16 hli. Peb tau muaj tus saib xyuas qhov chaw qhia rau peb tias lawv tau dhau los ntawm peb cov khoom siv hluav taws xob ntawm lwm tus neeg xa khoom 'cov hlau; nrog peb li, lub arc stability nyob twj ywm zoo ib yam, thiab lub spatter ntxuav nrog ib tug ceev txhuam.
Yog vim li cas "Thermal Movement" tseem ceeb dua Tensile Strength
Txoj haujlwm Middle East peb tau hais txog xyoo 2024 yog qhov kev tshawb fawb zoo tshaj plaws, tsis yog vim nws loj heev, tab sis vim tias qhov kub thiab txias ntawm huab cua viav vias tau ua phem heev - los ntawm ze li 50℃thaum nruab hnub rau ib tus lej thaum hmo ntuj hauv suab puam.
Hlau muaj cov coefficient ntawm thermal expansion uas yog kwv yees li ib nrab ntawm txhuas (12 × 10⁻⁶ /℃vs . 23 × 10⁻⁶ /℃). Qhov ntawd yog qhov txiaj ntsig loj heev rau cov pob qij txha sealant. Tab sis tsuas yog yog hais tias cov hlau yield zog (peb khiav Q355B ntawm ib tug zoo ib yam 375-395 MPa nyob rau hauv peb batch tests) nyob ruaj khov nyob rau hauv lub coil. Yog tias muaj qhov sib txawv ntawm 20 MPa hla lub kauj, koj cov yob- tsim cov mullions yuav muaj qhov sib txawv ntawm lub caij nplooj ntoos hlav{12}} rov qab. Koj lub vev xaib pab pawg xaus kev sib ntaus sib tua nrog shims. Peb txo qis qhov sib txawv los ntawm kev tswj hwm peb qhov kub thiab txias txias, yog li cov fabricators ntawm lwm qhov kawg tsis tas yuav rov ntsuas dua lawv cov brake presses.
Cov lus nug peb nug ua ntej peb hais
Thaum tus kws kho kab hlau rhuav phab ntsa xa email rau peb, kuv tsis xa daim ntawv teev nqi tam sim ntawd. Kuv nug ob lo lus nug tshwj xeeb:
"Dab tsi yog qhov koj xav tau facade lifecycle yam tsis muaj vaj huam sib luag loj tshem tawm?" (Yog tias lawv hais tias 20+ xyoo, kuv hais rau ZAM lossis hnyav - hnyav GI, tsis yog tus qauv Z100.)
"Puas yog koj txiav cov coils hauv -tsev?" (Vim yog tias koj yog, peb yuav tsum tau kho qhov hardness me ntsis kom cov npoo tsis micro- tawg thaum lub sij hawm slitting. Qhov no yog ib qho kev nthuav dav uas cov tub luam feem ntau saib dhau.)
Wrapping Up
Cov kab hlau rhuav phab ntsa yog lub ntsej muag ntawm lub tsev. Yog hais tias lub thav duab tom qab nws hloov, welds tawg, los yog xeb tawg, nws tsis yog ib qho teeb meem ntawm cov txheej txheem xwb - nws yog ib lub koob npe nrov rau txhua tus neeg koom tes. Peb tsis nyob ntawm no los muag koj "magic alloy." Peb nyob ntawm nomuab steeluas coj raws nraim li phau ntawv engineering hais tias nws yuav tsum, coil tom qab coil, yog li koj cov neeg tsim khoom tuaj yeem tsom rau kev teeb tsa, tsis yog kev tua hluav taws.
