Zuag qhia tag nrho, steel slag yog cov khoom siv ruaj khov thiab muaj ntau yam nrog ntau cov txiaj ntsig zoo, ua rau nws yog qhov zoo tshaj plaws rau kev siv ntau yam hauv kev tsim kho kev lag luam.

Yuav ua li cas yog Steel Slag thiab Slag kho thiab siv?

1. Kev kho steel slag:

Steel slag tau muab faib ua hluav taws xob rauv slag, qhib rauv slag thiab converter slag peb yam, kev siv ntawm steel slag feem ntau yog: pretreatment, muaj nuj nqis tivthaiv rov qab, siv los ua cov ntaub ntawv hauv tsev, metallurgy, kev ua liaj ua teb thiab lwm yam, ntawm cov khoom siv hauv tsev. txog li 40%; Nyob rau tib lub sijhawm, kev tshawb fawb ntawm pretreatment ntawm steel slag nyiaj txog li 32%, thiab ntau thiab ntau cov xim yog them rau cov pretreatment ua hauj lwm nyob rau hauv thaum ntxov theem, thiaj li yuav ua tau ntau conducive rau cov kev ua tau zoo ntawm cov khoom tom qab npaj.
Tam sim no, steel slag feem ntau yog siv los ua hauv av rau hauv micro hmoov los ntawm steel slag ntsug zeb, vim hais tias kev sib tsoo tsis yog tsuas yog ib tug txheej txheem ntawm particle txo, tab sis kuj nrog kev hloov nyob rau hauv siv lead ua qauv thiab nto lub cev thiab tshuaj zog, thiab cov kev ua ntawm steel slag micro hmoov tom qab sib tsoo tuaj yeem txhim kho tau zoo. Cov txheej txheem tseem ceeb ntawm steel slag hmoov yog qhov tshwj xeeb ntawm thaj chaw, qhov ntom ntom, cov ntsiab lus noo noo, dawb calcium, sulfur trioxide, alkalinity coefficient, kev ua haujlwm Performance index, stability, raws li kev ua haujlwm tau muab faib ua ib thiab ob.

2. Kev siv steel slag:

Cement fiber-raws li cladding cov khoom yog tsuas yog muaj nyob rau hauv plank hom nrog ib tug tuab ntawm ib ncig ntawm 8 hli thiab txawv qhov ntev. Koj tuaj yeem kho cov phiaj xwm no nrog cov hlau, cement lossis ntoo substrates yooj yim los ntawm cov ntsia hlau lossis cov nplaum. Daim ntawv thov cheeb tsam txawv raws li lub hom phiaj xws li sab nrauv phab ntsa, rooj vag, chaw tos txais, facades, thiab lwm yam.

Dab tsi yog Sand and Gravel Aggregate

Xuab zeb, gravel thiab crushed pob zeb yog tag nrho cov suav hais tias yog aggregates. Qhov yooj yim dua, cov khoom sib xyaw suav nrog cov nplej lossis cov pob zeb tawg. Lawv yog cov khoom siv tsis tau txuas ntxiv uas peb tau txais txiaj ntsig txhua hnub, tab sis tsis tshua xav txog.

Qhov zoo ntawm Sand thiab Gravel Aggregates

Assured tsim cov ntaub ntawv. Cov chaw rho tawm no muab cov khoom sib sau tsim nyog rau peb cheeb tsam txoj kev loj hlob thiab kev lag luam vam meej. Cov chaw hauv zos no pab txo tus nqi ntawm kev tsim kho thiab ua kom cov txheej txheem txhim kho sai, vim cov neeg ua haujlwm tsis tas yuav tos kom cov khoom sib sau ua ke los ntawm lwm thaj chaw.

Cov ntaub ntawv tsis tshua kim. Aggregate muab tau ntau ntawm nws tus nqi los ntawm kev nyob ze thaj chaw uas nws xav tau. Raws li ib tug natural geological deposit tsis pom nyob txhua qhov chaw, nws yuav tsum tau siv lub luag hauj lwm qhov twg nws tshwm sim. Qhov ntxiv tus neeg xa khoom yog los ntawm ib qhov project, qhov kim dua yog thauj khoom mus rau qhov chaw ua haujlwm. Ib daim ntawv tshaj tawm pom tias ib lub nroog ntawm 100,000 tib neeg tuaj yeem cia siab tias yuav them 1.3 lab ntxiv rau txhua qhov ntxiv 10 mais uas qhov sib sau nws siv yuav tsum tau nqa. Yog li ntawd, kev tsim kho cov nqi nce kom them tus nqi siab dua ntawm kev sib sau.

Tsawg tsheb thauj mus los. Siv cov chaw sib sau ua ke uas nyob deb ntawm txoj kev loj hlob txhais tau hais tias kev thauj mus los ntev dua yuav tsum muaj tsheb thauj khoom ntau dua, uas ua rau muaj tsheb thauj mus los, suab nrov thiab xwm txheej, nrog rau ntau cov hydrocarbons raug tso tawm rau hauv qhov chaw. Txawm li cas los xij, thaum cov chaw sib sau ua ke nyob ze rau thaj chaw uas kev tsim kho tiav, nws yuav pab txo qis cov tsheb thauj neeg hnyav ntawm peb txoj kev thiab txoj kev loj.

Kev cuam tshuam tsawg kawg nkaus. Qhov no txhais tau tias txhua qhov kev cuam tshuam yuav raug txwv rau thaj tsam tam sim ntawm kev ua haujlwm sib sau ua ke, yam tsis muaj kev cuam tshuam ib puag ncig.

Kev kho av. Tom qab lub xaib tsis siv lawm, nws tuaj yeem rov qab tau rau kev lom zem los ntawm cov tsiaj qus thiab cov neeg hauv zej zog. Cov av yuav rov qab mus rau ib qho chaw zoo nkauj, muab ntau lub sijhawm siv av thiab tsim kom muaj chaw zoo siab rau cov ecologies hauv zos kom vam meej. Kev coj ua kom rov zoo ua rau nws muaj peev xwm rov qab tau cov chaw rov qab mus rau kev siv tau zoo. Qee lub sij hawm, qhov chaw tuaj yeem rov qab ua ib puag ncig yam ntxwv. Hauv cheeb tsam Burlington, muaj ob qhov chaw tau txais rov qab uas tau raug txiav ua cov neeg nyob hauv tsev. Txoj kev kho kom zoo dua qub rau pob zeb quarries thiab lwm qhov chaw sib sau ua ke tau los ntev hauv xyoo tas los no, vim tias cov qauv kev kho kom rov zoo tau nce ntxiv thiab tsom mus rau qhov chaw tshwj xeeb ecologies.
