Asphalt yog ntau yam paving khoom siv hauv kev tsim kho, kho, thiab kho. Nws yog tsim los ntawm kev sib xyaw ntawm aggregates, muab tub lim, thiab bitumen. Asphalt mixing nroj tsuag (AMP) yog siv los tsim kub sib xyaw asphalt (HMA), uas yog hom feem ntau ntawm asphalt siv hauv kev tsim kho. Feem ntau muaj ob hom asphalt sib xyaw cov nroj tsuag:
- Batch Asphalt Mixing Cog:Batch asphalt nroj tsuag ua haujlwm los ntawm kev sib xyaw ua ke ntawm asphalt ntawm ib lub sijhawm. Lub batch loj yog feem ntau ntawm 4 thiab 8 tons. batch mixing txheej txheem pib nrog kev pub mis thiab ziab ntawm cov aggregates. Tom qab ntawd cov sib tov yog kuaj thiab ntsuas. Cov bitumen yog rhuab thiab hnyav thiab tom qab ntawd ntxiv rau lub tov khoom nrog rau cov aggregates thiab muab tub lim. Cov sib tov yog tov rau ib tug predetermined nqi ntawm lub sij hawm thiab ces tawm ntawm lub tov khoom.
- Nruam Asphalt Mixing Cog:Nruam asphalt cov nroj tsuag ua haujlwm los ntawm kev sib xyaw cov kwj ntawm asphalt tsis tu ncua. Cov aggregates, bitumen, thiab muab tub lim yog pub rau hauv lub tov khoom ntawm tus nqi tswj. Cov sib tov yog tov thaum nws mus los ntawm lub tov khoom thiab ces tawm ntawm lub tov khoom.
Qhov sib txawv tseem ceeb ntawm cov batch thiab cov nroj tsuag tsis tu ncua muaj xws li:
- Muaj Peev Xwm Ntau Lawm:Cov nroj tsuag tsis tu ncua feem ntau muaj peev xwm tsim tau ntau dua li cov nroj tsuag batch.
- Kev sib raug zoo:Nruam cov nroj tsuag tuaj yeem muab kev sib xyaw ua ke zoo dua vim muaj kev sib xyaw ua ke.
- Flexibility:Batch nroj tsuag tso cai rau kev hloov daim ntawv qhia yooj yim dua thiab kev koom ua ke ntawm cov khoom tshwj xeeb ntxiv.
- Tus nqi:Cov nroj tsuag tsis tu ncua tuaj yeem kim dua los yuav thiab ua haujlwm, tab sis lawv muab kev txuag nyiaj mus ntev los ntawm kev tsim khoom ntau dua thiab ua haujlwm zoo.
Ob hom asphalt mixing nroj tsuag muaj qee qhov sib txawv tseem ceeb, tab sis lawv ua raws li cov txheej txheem ntau lawm.
Asphalt Mixing Plant Production Process
- Aggregate Feeding thiab Stockpiling: Cov khoom txias txias, xws li qhov loj ntawm cov xuab zeb mus rau cov pob zeb loj, raug xa mus rau cov nroj tsuag thiab khaws cia rau hauv cov thawv cais. Qhov loj thiab hom kev sib sau ua ke yog nyob ntawm qhov kev npaj siv ntawm cov tiav asphalt mix.
- Kev ziab thiab cua sov: Hauv Batch Mixing Nroj Tsuag, cov khoom sib xyaw tau muab tso rau hauv lub tshuab ziab khaub ncaws ua kom sov los ntawm lub tshuab hluav taws xob. Qhov no dries thiab heats lub aggregates rau ib ncig ntawm 145-160 ° C; Hauv Cov Nroj Tsuag Sib Nqus, zoo ib yam li lub nruas tig los yog cov tshuab ziab me me txuas ntxiv kom qhuav thiab ua kom sov cov khoom sib xyaw ua ke thaum lawv loj hlob los ntawm cov nroj tsuag.
- Kev tshuaj ntsuam thiab kub cia:Kub aggregates los ntawm lub tshuab ziab khaub ncaws ces dhau los ntawm cov ntxaij vab tshaus vibrating kom cais lawv mus rau ntau qhov sib txawv. Cov kev sib sau loj no tau muab khaws cia rau hauv cov thawv kub sib cais kom txog thaum xav tau kev sib tov.
- Bitumen cua sov thiab cia: Bitumen, binding tus neeg sawv cev hauv asphalt, yog khaws cia rau hauv cov tso tsheb hlau luam thiab khaws cia ntawm qhov kub ntawm 155-160 ° C.
- Weighing thiab proportioning: Rau txhua pawg, cov txheej txheem ua ntej qhov sib piv ntawm cov kub sib sau ua ke, bitumen, thiab lwm yam khoom siv ntxiv xws li muab tub lim lossis cov khoom siv rov ua dua yog ntsuas qhov raug siab.
- Kev sib xyaw: Hauv Batch Mixing Nroj Tsuag, cov khoom hnyav tau muab pub rau hauv lub tshuab pug, lub tshuab loj kab rov tav, qhov uas lawv tau muab sib xyaw kom zoo rau lub sijhawm; Hauv Cov Nroj Tsuag Sib Nqus, cov ntaub ntawv sib xyaw tsis tu ncua thaum lawv taug kev los ntawm kev sib xyaw nruas lossis pug zeb.
- Kev xa tawm thiab xa tawm: Cov sib tov kub asphalt tiav lawm ces tawm ntawm lub tov khoom los yog nruas.
Cov txheej txheem ntxiv Variations
- Cov khoom siv rov ua dua tshiab:Qee cov nroj tsuag tuaj yeem suav nrog ib feem pua ntawm kev rov qab asphalt pavement (RAP) rau hauv kev sib xyaw kom ruaj khov thiab txuag nqi.
- Additives:Ntau yam additives tuaj yeem siv los txhim kho kev ua haujlwm ntawm asphalt sib tov, xws li cov polymers kom muaj zog tawg los yog hloov kho kom ua tau zoo dua hauv huab cua huab cua.
- Low-Temperature Asphalt: Kuj hu ua sov-mix asphalt (WMA), nws ua haujlwm los ntawm kev hloov kho cov txheej txheem kub-sib xyaw asphalt ntau lawm kom txo qhov kub ntawm asphalt yog tov thiab nteg.
Asphalt mixing nroj tsuag yog ib qho tseem ceeb rau kev tsim kho thiab kev kho ntawm txoj kev thiab txoj kev loj. Txawm li cas los xij, lawv tuaj yeem yog qhov tseem ceeb ntawm huab cua phem, tshwj xeeb yog hmoov av. Cov plua plav tawm los ntawm cov nroj tsuag asphalt tuaj yeem cuam tshuam tsis zoo rau tib neeg kev noj qab haus huv thiab ib puag ncig. Asphalt sib xyaw cov nroj tsuag ib txwm nyob hauv nroog txwv lossis hauv thaj chaw hauv nroog loj, thiab cov teeb meem ntawm cov plua plav cuam tshuam muaj kev txhawj xeeb rau cov tub ceev xwm, cov pej xeem, thiab cov tswv lag luam. Cov kab ke tswj kev ua paug huab cua tam sim no tau raug lees paub thoob ntiaj teb, ntau yam nrog cov kev cai tshwj xeeb tsom rau qhov kev ua haujlwm tshwj xeeb no, thiab tsis muaj cov nroj tsuag tshiab tau teeb tsa hnub no yam tsis muaj kev txwv tshwj xeeb rau kev tswj cov plua plav tawm. Tsis tas li ntawd, qhov kev thov loj hlob rau asphalt paving sib tov cov ntaub ntawv txhais tau hais tias ntau tshaj qhov nruab nrab ntawm kev siv zog yuav tsum tau siv los tswj cov plua plav tawm los ntawm asphalt sib xyaw cov nroj tsuag.
