Qhuav, hom thiab lub sij hawm ntawm validity ntawm MAAs

Maas yog ib tug ntawm cov yooj yim lub tsev ntaub ntawv. Yog tsis muaj nws tsis ua ib tug lub tsev. Nws yuav tsum tau rau lub strengthening ntawm lub hauv paus, thiab rau dai. Qhov no cov ntaub ntawv uas yog indispensable rau hnub no, thiab nws twb tsis muaj analogues. Lossis loj xaiv ntawm manufacturers thiab hom ntawm cement yog feem ntau nyuaj rau xaiv. Yog li ntawd koj yuav tsum to taub tag nrho cov subtleties thiab tricks tsis txhob miscalculate thiab tau nyob rau hauv lub kawg ib tug zoo tshwm sim. Optionally, koj muaj peev xwm yuav MAAs nyob rau hauv lub hnab los yog nyob rau hauv tej.

MAAs ntau lawm

Rau ob peb lub centuries, qhov no cov ntaub ntawv uas ntau lawm technology yog yuav luag unchanged. Tsuas yog kho tau technology thiab txo nqi rau qhov. Niaj hnub nimno khoom tso cai rau koj kom tau ib tug zoo cov khoom uas muaj zoo kev ua tau zoo.

Maas ntau lawm yog feem ntau nqa tawm raws li nram no:

• Limestone, uas yog lub ntsiab tivthaiv ntawm sib tov, tom qab extraction yog crushed rau hauv daim me me, tsis muaj ntau tshaj li 10 cm. Qhov no hnyav yog hu ua sludge. Ces nws yuav tsum tau crushed pheej txog thaum lub Desired taub hau.
• Tom qab ntawd, cov txheej txheem mus kom qhuav los yog moistening. Nws tag nrho cov nyob rau hauv dab tsi txoj kev yog siv nyob rau hauv qhov.
• Tom ntej no, lub resulting muab tshuaj txhuam yog raug rho tawm haujlwm nyob rau hauv ib tug cub tawg ntawm heev kub kom txog thaum tag nrho cov Cheebtsam pib rau yaj. Thaum lub sij hawm no theem lub MAAs clinker yog tsim nyob rau hauv daim ntawv ntawm cov me me lumps.
• Tom qab ntawd nws tau ua tib zoo as mus rau ib tug hmoov.
• Cov theem tom ntej yog yus muaj los ntawm qhov sib ntxiv ntawm gypsum. Nws yuav tsum muaj xwb 5%. Qhov no yuav ua rau kom lub stickiness ntawm lub xis mas. Tsis tas li ntawd, los txhim kho cov ntaub ntawv uas cov yam ntxwv ntawm cov ntau yam ntxiv thiab minerals.

Main yam ntxwv thiab cov khoom

Sawv daws yeej paub lub check zoo tshaj ntawm cov muaj pes tsawg leeg, tab sis tsis muaj ib tug xav tias hais txog nws cov lwm yam zoo. Zoo MAAs, tus yam ntxwv uas lub siab tshaj plaws, ntawm chav kawm, yuav sib txawv nyob rau hauv nqe thiab labeling. Tab sis them mloog kom nws lwm yam tsis, koj yuav xaiv tau lub high-tech khoom uas txig tiv nrog lawv paub tab thiab ua tau raws li koj lub siab xav.

Ib tug ntawm cov tseem ceeb tshaj plaws yam ntxwv yog kuj mus corrosion. Muaj ntau ntsib nrog qhov teeb meem ntawm ua txhaum lub meej mom ntawm lub txheej ntawm MAAs vim qhov tus ntawm ib tug txhoj puab heev ib puag ncig, los yog ntev li kev sib cuag nrog tib yam dej. Cas sim haum cov kev pab cuam lub neej ntawm MAAs thiab kom nws muaj kev ruaj ntseg, koj yuav tsum them sai sai mus rau lub muaj pes tsawg leeg. Nyob rau hauv Feem ntau, pab tau kom lub dag lub zog ntawm ib tug sib tov ntawm tshwj xeeb polymer additives.

Nyob rau hauv lub chaw ua khoom ntawm cov tshuaj xyuam xim rau cov nqi ntawm cov dej ntxiv rau tus qhuav sib tov. MAAs microparticles muaj ib tug peb lub sij hawm ntau dua ceev thiab muaj peev xwm mus nqus txawv cov nqi ntawm cov kua. Yog hais tias koj tsis twv nrog cov lus teb ntawm no hais yuav txiav txim, thaum lwm tus ib nrab ntawm lawv, nyob rau hauv tsis tooj, tom qab ib tug tej lub sij hawm sawv rau ntawm qhov chaw. Raws li ib tug tshwm sim, tsis muaj lub dag lub zog thiab nyhav rau puas.

Lub fineness ntawm MAAs hniav sib tsoo muaj feem xyuam rau ob qho tib si qhov zoo tshaj li zoo li, ntsig txog, thiab nyob rau hauv tus nqi ntawm cov khoom. Cov me tus hais, qhov ntau lawv yuav tawv sai, thiab lub siab rau lawv lub neej. Tab sis tsis yeej ib txwm, ib tug me me kom muaj nuj nqis ntawm microparticles nrog ib tug zoo tshwm sim. Sim xaiv cov pom piv ntawm zoo thiab qias neeg. No thaum lawv tseem yuav kom cov cia siab rau ntawm cov ntaub ntawv uas nyob rau hauv lub neej yav tom ntej.

Nws tseem yog ib qho tseem ceeb coj mus rau hauv tus account ntsuas ntawm lub dag lub zog thiab tshav kub tsis kam. Yuav tsis tau underestimated yog ib tug ntawm cov saum toj no cov yam ntxwv. Tag nrho cov ntawm lawv yog cov tseem ceeb thiab yog cov uas tseem ceeb. Rau kev pom kev ua hauj lwm, manufacturers sim mus ua ke tag nrho cov qhov zoo tshaj plaws nyob rau hauv ib yam khoom. Tab sis muaj cov neeg uas yog vim cov yuav txo tau ntawm ib co yam ntxwv ho txhim khu lwm tus neeg. Ntawm no, txhua leej txhua tus xaiv nws tus kheej version, nyob rau hauv raws li cov kev pab raws qib thiab kev ntshaw.

Tej yam kev mob ntawm cia ntawm MAAs

Nyob rau hauv thiaj li hais tias cov ntaub ntawv uas tau poob tsis muaj leej twg ntawm nws cov qualities, nws yog tsim nyog los soj ntsuam cov tej yam kev mob ntawm cia thiab siv, yuav tsum tau los ntawm lub chaw tsim tshuaj paus. Tsuas yog qhov no yuav xyuas kom meej tus ntsuam ntawm cov khoom rau ntev ua luaj li (los yog txawm ntev), raws li tau cog lus tseg los ntawm cov chaw tsim tshuaj paus.

MAAs warehouse yuav tsum qhuav. Qhov no yog tej zaum qhov tseem ceeb tshaj plaws yuav tsum tau cia cov ntaub ntawv. Qhov no yog vim, feem ntau, nrog rau lub thaj chaw ntawm MAAs surge (txawm los ntawm cov huab cua). Rau tib lub hom phiaj yuav tsum tau zoo ventilated. Maas nyob rau hauv lub hnab, uas yog xa mus rau cia, nyob rau ib tug yuav tsum hauv paus yuav tsum tau soj ntsuam txog kev ncaj ncees ntawm lub ntim.

Term Cia MAAs

Yog hais tias koj coj lub nruab nrab nqi, daim duab feem ntau yog hom twg los ntawm 2 lub hlis. Txee lub neej ntawm MAAs nyob ntawm ntau yam tseem ceeb thiab tej zaum yuav txawv. Rau high-ceev hom, qhov no daim duab yog txawm tsawg - txog 1.5 lub hlis. Nws yog yog li ntawd tseem ceeb heev them sai sai mus rau lub hnub tim uas siv thiab ua thiab expiry hnub teev xis mas.

Nyhuv ntawm extraneous yam

Maas zoo yuav muaj cuam tshuam los ntawm txoj kev ntawm nws cia, tsheb thauj mus los txoj kev thiab cov khoom hom nws tus kheej. Thaum careless tuav decompression yuav tshwm sim nrog rau lub thawv thiab qhuav sib tov vernal nqus dej los ntawm ib puag ncig. Qhov no tsis tsuas yuav txo cov txee lub neej ntawm MAAs, tab sis kuj tsis pub nws paub txog tej yam khoom. Yog li ntawd, cia tej yam kev mob yuav tsum tau ntsib, thiab lub sib xyaw kom haum yog tau ntim rau hauv ib tug tshwj xeeb hermetically kaw lub hnab. Nyob rau hauv cov tej yam kev mob, lub txee lub neej ntawm lub MAAs yuav tsum yog los ntawm 1 mus rau 2 xyoos.

hom sib tov

Muaj ob peb hom ntawm cement, txhua yam uas ib tug txawv pes tsawg leeg thiab raw cov ntaub ntawv. Cov nram qab no yog cov feem ntau:

• Txiv qaub.
• Marly.
• Av nplaum.

Cov hom muaj tus loj tshaj kuj mus dej thiab kub extremes:

• Portland.
• Shlakoportland.

Qhov no zoo ntawm MAAs yog yus muaj los ntawm nws cov hardness thiab kuj mus corrosion.

• Hydraulic. Sai nqus dej thiab sai hardens.
• Backfill. Nws yus siab zog thiab feem ntau siv nyob rau hauv kev tsim kho ntawm dams thiab lwm yam dej-resistant lug.
• Hniav. Nws muaj ib tug nruab nrab dawb xim thiab yog siv rau cov xov ua hauj lwm.
• Sulfate. Mas muaj tsawg kawg nkaus kub.
