Dab tsi yog Aluminium Checkered Phaj yog
Aluminium checkered phaj, tseem hu ua tread phaj los yog pem teb phaj, yog ib daim ntawv los yog phaj khoom nrog ib tug tsa qauv dov rau hauv ib los yog ob lub ntsej muag. Cov qauv tsis luam tawm lossis siv tom qab: nws yog tsim los ntawm cov qauv yob thaum lub sij hawm kawg dov dhau, yog li cov tuav tuav yog ib qho tseem ceeb nrog lub hauv paus hlau thiab tsis tuaj yeem tev lossis hnav.
Ob qhov ntev piav txog cov khoom. Lub hauv paus tuab yog ntsuas ntawm thaj tsam tiaj tus ntawm cov tuav, thiab qhov siab tag nrho suav nrog cov qauv, uas feem ntau ntxiv txog 0.5-1.5 hli rau tsib-bar qauv. Kev yuav ntawm tag nrho qhov siab es tsis txhob ntawm lub hauv paus thickness yog ib qho yuam kev, vim hais tias lub load-nqa seem yog lub hauv paus hlau. Daim ntawv thiab phaj ntawm hom no tau teev tseg raws li ASTM B209 rau kev lag luam thoob ntiaj teb, EN 485-2 hauv Europe, thiab GB / T 3880.2 hauv tsev.
Alloys, Tempers thiab Qauv Hom
Peb cov alloys npog yuav luag txhua qhov kev xav tau ntawm kev lag luam, thiab kev kub ntxhov rau cov khoom lag luam yog tus lej plaub, 4, los qhia tias qhov chaw yog qauv.
| Alloy | Kev sib xyaw thiab tus cwj pwm | Tej tempers | Qhov twg nws siv |
|---|---|---|---|
| 3003 | Al-Mn, txog 1.0-1.5 % Mn; zoo formability, weldability thiab dav corrosion kuj | H22, H24, H114 | general flooring, toolboxes, tsheb trim, hniav panels |
| 5052 | Al-Mg, txog 2.2-2.8 % Mg; lub zog siab tshaj plaws ntawm cov uas tsis yog -kub-kho tau khub thiab zoo tshaj plaws marine corrosion kuj | H32, H34, H114 | tsheb thiab trailer pem teb, marine decks, offshore walkways |
| 6061 | Al-Mg-Si, kub- kho tau; siab tshaj hardness thiab lub zog, qis formability | T6 | structural platforms, ramps, machinery guarding |
Cov qauv geometry raug xaiv kom haum rau kev khiav tsheb thiab cov dej ntws. Tsib-bar tread muaj cov kab khiav hauv ob qho kev qhia thiab muab kev tuav zoo ib yam hauv txhua qhov kev mus ncig, uas yog vim li cas nws ua rau muaj kev lag luam hauv pem teb. Ob -bar, lossis pob zeb diamond, qauv muaj cov kab hauv ib qho kev taw qhia thiab muaj ntau yam ntawm lub cev tsheb thiab kev ua haujlwm zoo nkauj. Stucco embossed thiab lentil qauv siv me me, denser nta thiab tau teev tseg qhov twg zoo nkauj zoo nkauj xav tau ntau dua li qhov siab tshaj plaws traction.
Mechanical Properties thiab Tolerances
Cov txiaj ntsig zoo rau cov qauv sib xyaw ua ke yog qhia hauv qab no. Cov nqi xa mus rau lub hauv paus hlau thiab sib txawv nrog ntsuas, yog li lawv tau teev raws li qhov tsawg kawg nkaus lossis ib txwm muaj ntau yam tsis yog ib daim duab.
3003-H22 / H24: tensile lub zog kwv yees li 140-200 MPa, yield zog txog 115-125 MPa yam tsawg kawg nkaus, elongation nyob ib ncig ntawm 8-10% ntawm qhov hnyav dua
5052-H32 / H114: tensile zog txog 215-275 MPa, yield zog txog 160 MPa yam tsawg kawg nkaus, elongation txog 7-12%
6061-T6: tensile zog txog 290-310 MPa, yield zog txog 240-275 MPa, elongation txog 8-10%
Qhov ceev: 2.73 g / cm3 rau 3003, 2.68 g / cm3 rau 5052, 2.70 g / cm3 rau 6061
Standard thickness ntau: txog 1.5-8 hli puag thickness, nrog cov qauv heights ntawm 0.5-1.5 hli; dav txog li 1500-2000 mm
Dimensional tolerances, flatness thiab camber ua raws li daim ntawv thiab phaj txheem hais ntawm qhov kev txiav txim. Vim hais tias tus qauv yog dov rau hauv, thickness kam rau ua yuav tsum yeej ib txwm pom zoo raws li lub hauv paus thickness, thiab cov ntsiab lus ntsuas yuav tsum tau sau rau hauv daim ntawv tshuaj ntsuam.
Slip Resistance thiab Safety
Traction Performance yog ntsuas ntau dua li qhov xav tau. Qhov kev ntsuam xyuas ramped hauv DIN 51130 faib cov khau khau khiab los ntawm R9 txog R13, thiab DIN 51097 ua tib yam rau cov chaw tsis muaj taw nyob rau hauv cov dej ntub dej, siv cov chav kawm A, B thiab C. Qhov raug dov tsib-bar txhuas phaj feem ntau ncav cuag R10 txog R11; cov chav kawm siab dua yuav tsum muaj qhov sib sib zog nqus, qhib ntau dua, uas tseem nyuaj dua los ntxuav.
Peb cov ntsiab lus ua raws li. Ua ntej, lub phaj qhuav tsis yog qhov tsim qauv rau hauv pem teb: xyuas qhov kev tiv thaiv nrog cov kab mob uas yuav tshwm sim tiag tiag, txawm tias dej, roj lossis zaub mov pov tseg. Qhov thib ob, tus qauv qhov tob yuav tsum muaj sia nyob ntawm kev pabcuam lub neej, yog li kev siv tshuaj abrasive thiab aggressive acidic cleaners yuav tsum raug zam. Thib peb, muab cov dej ntws mus rau hauv cov kev taw qhia cov tuav, vim tias cov qauv raws cov kua dej tawm ntawm qhov kev taw qhia bar ntau dua li hla nws.
Kev siv, Fabrication thiab tu
Cov ntawv thov txheej txheem suav nrog kev taug kev thiab cov platforms, stair treads thiab nosings, tsheb thauj khoom thiab trailer pem teb, chaw thau khoom ramps, tshuab guarding, marine decking, toolboxes, dock boards thiab, nrog rau cov qauv sib dua, zoo nkauj architectural thiab signage ua hauj lwm.
Fabrication yog ncaj nraim rau cov uas tsis yog - cua sov- kho tau tempers: 3003 thiab 5052 tuaj yeem raug txiav, sawn, drilled, khoov thiab welded nrog cov qauv siv, thiab 5052 muaj qhov zoo dua qaug zog thiab kev coj tus cwj pwm ntawm ob. 6061-T6 qib yog qhov muaj zog dua tab sis nws yooj yim dua rau kev tawg thaum lub sijhawm khoov nruj, yog li nws yuav tsum tau tsim nrog cov radii dav dav thiab, qhov tsim nyog, ua ntej-rhuab hauv zos. Vuam tshav kub txo lub zog nyob rau hauv ib tug nqaim cheeb tsam ntawm lub weld nyob rau hauv lub ua hauj lwm-hardened tempers, yog li cov txheej txheem pob qij txha feem ntau yog tsim los nrog lub tshav kub cuam tshuam cheeb tsam coj mus rau hauv tus account.
Kev tu yog tsawg heev. Aluminium tsim nws tus kheej tiv thaiv oxide zaj duab xis, yog li tsis muaj kev pleev xim lossis xeb yuav tsum tau kho. Ntxuav nrog xab npum me me thiab dej, ua raws li kev yaug, yog txaus; abrasive pads, hlau txhuam thiab muaj zog alkaline los yog acidic cleaners puas oxide zaj duab xis thiab cov qauv. Kev tshuaj xyuas ib ntus ntawm siab- thaj chaw tsheb khiav mus rau qhov chaw tiaj tus lossis hnav, thiab rov ua kom nruj lossis hloov kho, ua kom lub installation ua haujlwm rau nws lub neej kev pabcuam tag nrho.
Cov lus nug nquag
Q: Puas yog cov qauv checkered siv rau cov hlau lossis dov rau hauv nws?
Nws yog dov rau hauv lub phaj los ntawm cov qauv rolls thaum lub sij hawm kawg dhau, yog li cov tuav yog ib feem ntawm lub hauv paus hlau thiab tsis tuaj yeem de- laminate lossis tev tawm hauv kev pabcuam.
Q: Yam hlau twg yuav tsum tau xaiv rau sab nraum zoov lossis marine siv?
5052 feem ntau yog qhov kev xaiv raug vim tias nws cov magnesium ntxiv muab qhov zoo tshaj plaws corrosion kuj thiab qaug zog ua haujlwm ntawm tus qauv tread phaj alloys, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig chloride.
Q: Lub checkered phaj thickness txhais li cas?
Los ntawm lub hauv paus thickness, ntsuas ntawm qhov chaw tiaj tus ntawm cov tuav. Qhov siab tag nrho suav nrog cov qauv thiab loj dua li ntawm 0.5-1.5 hli rau cov khoom siv tsib-bar.
Q: Dab tsi hauv chav kawm ntawv qib siab tuaj yeem xav tau?
Muaj tsib-bar tread phaj yog feem ntau cais R10 txog R11 nyob rau hauv qhov kev sim ramp hauv DIN 51130, nrog rau cov chaw ntub dej tsis muaj kev ntsuam xyuas cais raws li DIN 51097.
Q: Can checkered phaj yuav welded thiab khoov?
Yog lawm. Cov qib 3003 thiab 5052 khoov thiab txuas tau yooj yim nrog cov qauv txheej txheem. 6061-T6 qib xav tau kev khoov dav dav thiab cov cua sov hauv zos ua ntej, thiab nws thaj chaw tshav kub poob qis zog tom qab vuam.
Q: Puas yog lub phaj xav tau kev kho saum npoo los tiv thaiv corrosion?
Tsis yog rau tej huab cua. Lub ntuj oxide zaj duab xis yog txaus, thiab txhuas tsis xeb. Kev pleev xim tsuas yog yuav tsum muaj nyob rau hauv cov kua qaub, alkaline lossis ntsev- ib puag ncig, uas yuav tsum tau teev cov txheej txheem hloov kho kom haum lossis xim xim.
