# Kev nkag siab thiab siv cov nroj tsuag ashwv Peb tshawb txog qhov tseem ceeb ntawm sma sib tov tsim thiab muab kev pom kev ua haujlwm rau cov kws tshaj lij hauv kev lag luam asphalt.

Pob Zeb Masthing Asphalt (SMA)?

Asphalt Tsob Nroj Sma, lossis pob zeb mastic evast asphalt, yog kev ua haujlwm siab asphalt sib tov tsim nyog xav tau cov ntawv thov durabilation thiab tsis kam mus rutting thiab qaug zog tawg. Tsis zoo li kev sib xyaw ua ke Asghalt, SMA siv cov qhab nia siab ntawm pob zeb ua haujlwm thiab cov qauv tsim tshwj xeeb, suav nrog cov qauv ntom, kis tus qauv. Qhov no txawv txawv kev ua haujlwm ua rau nws cov yam ntxwv zoo tshaj plaws. Nkag siab cov intricacies ntawm Asphalt Tsob Nroj Sma yog qhov tseem ceeb rau kev ua tiav cov chaw siab zoo.

Qhov tseem ceeb ntawm sma mixes

Qhov ua tiav ntawm Asphalt Tsob Nroj Sma Kev tso siab rau ntau yam ntawm cov kev sib npaug ntawm nws cov khoom siv. Cov no suav nrog: kev sib sau: SMA feem ntau siv cov kis tus qauv-kawm tiav cov qauv sib txawv, ua kom pom tseeb particle ntim ntom. Kev kawm tiav kev sib sau yuav tsum ua tib zoo tsim kom ua tiav cov kev ruaj khov zoo nkauj thiab ua kom ntev. Binder: Lub phau ntawv cim, feem ntau tau hloov kho bitumen, plays lub luag haujlwm tseem ceeb hauv kev ua tau zoo ntawm SMA. Qhov kev xaiv ntawm bitumen nyob ntawm huab cua kev mob thiab kev ua tau zoo. Muab tub lim: fillers, xws li limestone hmoov, txhim kho kev ua haujlwm ntawm kev sib xyaw thiab sau cov voids ntawm cov khoom sib cav sib ceg, ua rau muaj kev kub ntxhov. Ntxiv: Ntxiv, xws li polymers lossis fibers, tuaj yeem txhim kho kev ua tau zoo ntxiv rau kev tawg thiab rutting.

Kev tsim qauv thiab tsim cov SMA hauv tsob ntoo asphalt cog

Kev tsim cov khoom muaj txiaj ntsig zoo Asphalt Tsob Nroj Sma yuav tsum tau npaj ua tib zoo npaj thiab kho kom meej thoob plaws tag nrho cov txheej txheem. Qhov no cuam tshuam:

Sib tov tsim kev txiav txim siab

Tsim kom muaj zog Asphalt Tsob Nroj Sma Sib tov tsim tau cov ncauj lus kom ntxaws ntawm ob peb yam: cov khoom siv ntawm cov kev kawm, suav nrog cov kev kawm, thiab kev ua tau zoo, thiab kev ua tau zoo ntawm cov sma mix. Cov ntawv xaiv phau ntawv: kev xaiv ntawm cov bitumen tsim nyog yog qhov tseem ceeb rau kev ua tiav cov yam ntxwv zoo hauv ntau yam. Cov ntsiab lus sau ua ke: tswj cov cov ntsiab lus muab tub lim yog tseem ceeb heev rau qhov xav tau yam uas xav tau thiab ua haujlwm ntawm kev sib xyaw. Additive kev ua kom zoo: hom thiab kom muaj nuj nqis ntawm cov roj ntxiv uas siv yuav tsum tau ua tib zoo ua kom tau raws li cov hom phiaj ua tau zoo.

Cov Txheej Txheem Txheej Txheem Txhim Kho

Cov khoom siv asshalt ua tau zoo tshaj plaws rau ntau cov kauj ruam tseem ceeb: qhov tseeb uas muaj qhov hnyav thiab ua kom muaj qhov tseem ceeb rau kev sib xws. Kev sib xyaw lub sijhawm thiab kub: ceev faj tswj ntawm lub sijhawm sib xyaw thiab ntsuas kub ua kom zoo sib xyaw homogenous. Kev ntsuas kev tswj hwm zoo: Kev tswj hwm zoo ib txwm muaj tseem ceeb heev los xyuas kom cov sib xyaw ua raws li cov lus qhia uas yuav tsum tau ua.

Cov txiaj ntsig ntawm kev siv SMA

SMA muaj ob peb qhov zoo piv rau cov paphalt sib tov: | Nta | Tshuab | Pom zoo asphalt || ------------ | ---------- || Rutting tsis kam | Ho siab dua | Qis dua || Qaug zog tawg | Ho siab dua | Qis dua || Dej tsis kam | Zoo heev | Nruab Nrab || Durability | Siab | Nruab nrab |

Yog xav paub ntxiv txog cov khoom siv zoo li asphalt zoo cog ntoo, mus xyuas Zibo Jixiang Machinery Co., Ltd. Tus neeg xa khoom ntawm asphalt cog thev naus laus zis. Lawv cov kws tshaj lij hauv Asphalt Tsob Nroj Sma Kev daws teeb meem ua kom muaj kev ua tau zoo thiab ua tau zoo.

Ntse siv Asphalt Tsob Nroj Sma Yuav tsum muaj kev nkag siab meej ntawm kev tsim cov qauv tsim thiab cov txheej txheem ntau lawm. Los ntawm cov kev xaiv ua tib zoo xaiv cov khoom siv, ua kom zoo dua cov tsis muaj, thiab siv cov kev ntsuas kev ntsuas zoo, koj tuaj yeem ua tiav kev ua haujlwm zoo tshaj plaws thiab kev ua haujlwm ntev. Nco ntsoov, xaiv cov cuab yeej txoj cai yog tus yuam sij rau kev ua tiav hauv kev ua cov sma zoo.
