Maas mortar: Muaj pes tsawg leeg thiab siv thiab ua

Cov MAAs slurry yog ib tug heev check cov ntaub ntawv uas, nws sai sai teev thiab hardens nyob rau hauv cov huab cua. Pib qhov chaw ntawm ib tug kub ntawm 20 degrees tshwm sim nyob rau hauv hais txog peb lub quarters ntawm ib teev. Cov tshuaj yuav tsum tau ua ntawv thov tsis pub dhau ib teev tom qab nws npaj, txij li thaum txwv tsis pub nws loses nws lub zog. Muaj ib tug ntau yam ntawm MAAs - nws yog nyob ntawm ntau yam. Qhov npaj kev daws teeb meem nyob rau hauv lawv lub hauv paus muaj ntau compressive zog.

Yuav ua li cas yuav ua rau MAAs cug

Yuav kom npaj lub MAAs slurry yuav tsum tshau xuab zeb thiab xis mas los ntawm ib tug sab cib nrog ib lub qhov txoj kab uas hla ntawm 3 hli. Cov khoom xyaw yog taub txua volumetric koob tshuaj thiab mixed kom txog thaum homogenous, thiab yog hais tias tsim nyog, sieved dua thiab lub qhuav sib tov ntxiv cov dej, kom txog thaum ib yam thickness.

Rau tso yeeb nkab saum toj no lub-ru tsev yog ua los nyuab dua mortar muaj muab tub lim thiab ob losis tswvyim dabtsi Cheebtsam: xuab zeb, MAAs thiab txiv qaub putty. Nyob rau hauv cov ntaub ntawv no, koj yuav tsum ntxiv ib feem xis mas mus rau peb qhov chaw txiv qaub mus rau 15 qhov chaw xuab zeb.

Slurry yog siv los npaj qhob hmoov sib tov. Nteg tshiab qhob cover chips los yog matting, nplua mias tso zis dej. Qhov no yog tshwj xeeb tshaj yog ua nyob rau hauv thawj tsib hnub tom qab ib tse nrog koj formwork, rau cov hom phiaj no kuj siv polyethylene zaj duab xis uas tsim ib tug chav nyhuv.

Maas mortar: Muaj pes tsawg leeg

Maas mortar rau cov kev siv yuav tsum tau muas los yog ua ntawm nws tus kheej los ntawm nws nyob rau hauv tej yam ratios ntawm MAAs thiab xuab zeb (ntawm 1 mus rau 3, nyob ntawm seb lub ua li 1 mus rau 6). Nws yuav tsum tau nco ntsoov tias twb manually tsim ib qho kev daws tsis tau tsuas yog tsho, tab sis nws yog yuav luag tsis yooj yim sua rau tusyees faib tag nrho lub Cheebtsam tsis muaj tus tsim nyog kev. Tswv yim rau siv tus tov khoom (txhua yam los yog hluav taws xob), uas yuav tsum tau ob leeg muas thiab khiab tsev nyob, borrowed los ntawm cov phooj ywg.

Heev nrov yog ib tug xis mas slurry, uas yog siv rau cov ntaus ntawv brickwork. Qhov no tej zaum yuav thov ob hom ntawm kev daws - MAAs thiab xis mas-txiv qaub. Nrog rau thawj hom tsa load-tau cov kabmob phab ntsa thiab lwm yam hais, thaum lub sij hawm thib ob muaj pes tsawg leeg yog siv rau tej hom ntawm cov ntaub ntawv (clutch puab phab ntsa), thiab nws ntxiv xwb ib feem me me ntawm MAAs.

Yog hais tias lub tshuaj khib yog siv nyob rau hauv lub caij ntuj no, nws yog tsim nyog los siv dej ntsuab additives, uas tsis pub kom khov tshuaj. Tseem, ntawm ib tug kub hauv qab no 20 degrees Celsius MAAs loj yog zoo dua tsis ua li cas, raws li cov no Cheebtsam tsis ua hauj lwm. Siv ib tug tov ntawm ntau yam additives yuav tau muab cov kev tsim nyog yooj thiab muaj. Yuav kom nce lub ductility tshuaj cov tub txawg zoo tib yam tsuaj zawv plaub hau ntxiv los ntawm pouring ib tug ib nrab-liter ntawm ib yam khoom nyob rau hauv ib tug cubic Meter ntawm lub MAAs ceeb thawj. Cov ntsev yog li ib tug dej ntsuab additives, txawm heev heev tswv yim pom zoo, ncuav yuav tsum tsis txhob yuav kom tsis txhob muaj cov tsos ntawm efflorescence.

Maas thiab qhob khoom Thaum tshav kub kub resistant mixtures uas yog siv rau zus tau tej monolithic lug foci nrog rau kev qhib hluav taws, mus rau ib tug firebox los yog lub tshuab cua sov masonry blocks. Yuav kom tsim ib tug nplaim taws resistant refractory kev daws teeb meem uas siv cov nram qab no Cheebtsam thiab proportions. Yog hais tias cov tshuaj yog yuav tsum tau siv los tsim txhab nrog rau kev qhib hluav taws, coj MAAs kos yog tsis qis tshaj li 400. Rau ib feem twb ntxiv ob qhov chaw ntawm crushed pob zeb, muaj raws ntawm liab cib, ob qhov chaw ntawm quartz xuab zeb los yog los ntawm fine liab fireclay cib, thiab ib tug thib peb los ntawm fine xuab zeb. Yuav kom ua tau ib lub firebox noj tib yam MAAs, crushed pob zeb ntawm bricks thiab firebricks zoo tib yam xuab zeb nyob rau hauv proportions ntawm 1: 2: 2: 0,33.
