Kev noj ib 1m2 ntawm plaster. Tau ntawm gypsum plaster thiab xis mas

Plastering ntawm phab ntsa tso cai rau lawv los mus ua kom tus thiab zoo, thiab tiv thaiv cov nyom ib puag ncig yam tseem ceeb. Ua ntej yuav pib ua hauj lwm nws yog ib qho tseem ceeb kom raug xam tus nqi yuav tsum tau qhuav sib tov. Tiav lawm plaster hardens tom qab ntxiv dej heev sai sai. Yog li ntawd, lub count yuav tsum tau kom portioned, thiab rau tagnrho ntawm nws. Tag nrho cov no yuav pab tau kom tsis txhob ruaj siv thiab txhim kho cov kev kawm ntawv ntawm cov xov tej hauj lwm.

ntau ntau yam plasters

Muaj ntau ntau yam tseem ceeb uas cuam tshuam rau lub khiav ntawm plaster rau 1m2. Ua ntej ntawm tag nrho cov, cov xov tooj uas yuav tsum tau qhuav sib tov nyob rau hauv nws cov hom. Rau cov phab ntsa yuav siv tau:

• Plaster. Qhov no zoo ntawm mixtures yog tsuas yog siv rau kawm tuab si lug ntawm phab ntsa thiab ceilings nyob rau hauv lub chaw. Los ntawm txoj kev thiab tshav puam rau xov chaw yuav siv tsis tau, vim hais tias lawv tsis tso siab dhau heev lawm cov av noo thiab ceev kub hloov. Ib qho ntawm feem nrov hom ntawm no hom ntawm plaster "Rotband".
• Cementitious mixtures thereof. Cov ntaub ntawv no yog siv rau kho kom zoo nkauj nrog cov pwm los yog sab nraum zoov chaw.
• Hniav plaster. Feem ntau thov thinly thiab ua hauj lwm raws li kawg finishing.

Lub curvature ntawm cov phab ntsa

Qhov no yog tseem ceeb uas muaj feem xyuam rau cov ndlwg ntawm plaster. Rau tag cov phab ntsa du tag sib tov yuav tsum tau tsawg dua. Yog hais tias muaj yog hloov los ntawm kab rov tav los ntsug dav hlau nto nrog plastering muaj dlhos. Ntawm cov hoob kawm, nyob rau hauv cov ntaub ntawv no, lub sib tov yuav tsum tau ntau dua. Ua noj nyob rau hauv lub xov plaster thiab yog hais tias tus phab ntsa yog sis tsis ncaj: lub qhov taub, loj tej kab nrib pleb, chips, thiab lwm yam ...

Tau ntawm qhuav plaster

Qhov no yog heev yig hom sib tov. Rau cov phab ntsa thiab ceilings muaj sib npaug zos cheeb tsam plaster feem ntau yuav tsum tau 2-3 lub sij hawm me dua cov xis mas. Cov pom zoo thickness ntawm txheej thaum siv no txhais tau tias -. 1 cm txaus plaster 1m2 nyob rau hauv rooj plaub no yuav yog hais txog 9 kg. Txawm li cas los, yog hais tias muaj yog tsis muaj irregularities ntawm cov phab ntsa, nws yog tau tso cai grout txheej thickness ntawm 0.5 cm. Nyob rau hauv cov ntaub ntawv no, cov khiav, ntsig txog, kuj halved.

Cov feem nrov stucco hnub no yog ib txoj kev "Rotband". Manufactured compositions ntawm no hom nyob rau hauv lub domestic qhauj nyiaj ua lag luam los ntawm cov tuam txhab German "Knauf". Plaster "Rotband", uas ntws yog 8.5 kg ib 1 m ^2, - ib tug txhais tau tias ntawm qhov zoo thiab yog li heev yig.

MAAs compositions

Ndlwg plaster 1m2 nyob rau hauv cov ntaub ntawv no yuav hais txog 16-18 kg. Cov nuj nqis yog li npaj txhij mus cia nyiaj, raws li zoo raws li rau manufactured nws tus kheej. Muaj pes tsawg leeg ntawm no plasters feem ntau muaj xws li xis mas thiab xuab zeb. Lub volume ratio ntawm 1: 3. Li ntawd, cov MAAs yuav tsum tau hais txog 4.5 kg ib m ^2. Rau plasters zoo coj lub siab qib material, e.g., M400. Xuab zeb 1 m ² 13,5 kg xav tau. Ua ntej lub batch nws yuav tsum tau sifted.

Tej zaum cov plaster ua rau lub hauv paus ntawm MAAs nrog rau qhov sib ntxiv ntawm txiv qaub sib tov. Feem ntau lawv yuav tawm ntawm txee. Rau ib tug ca saum npoo MAAs-txiv qaub plaster yog feem ntau thov nyob rau hauv ob khaubncaws sab nraud povtseg: ib tug pre-txau thiab finish lub tsho tiv no. Yog li ntawd, nws noj yog tseem ceeb.

hniav plaster

Rau tag lub deg hauv cheeb tsam ntawm 1 m ² ntawm cov ntaub ntawv uas tej hom xav tau ib tug nruab nrab ntawm txog 8 kg. Tab sis nyob rau hauv cov ntaub ntawv no nws nyob ntawm seb yam ntawm cov hniav sib tov. Heev nrov thaum lub caij no, piv txwv li, npaj mas rau facades txhais tau tias "tawv". Plaster (nws noj yog dog dig tsawg dua) rau no hom ntawm heev zoo. Rau tag 1 m ² ntawm qhov chaw yuav siv sij hawm txog 2.5-3 kg "tawv kab" nyob rau hauv ib tug txheej thickness ntawm lub 1 hli.

ntim servings

Lub neej ntawm ib tug plaster tshuaj heev me me: nyob rau nruab nrab, qhov loj hardens nyob rau hauv 20-25 feeb. Yog li ntawd, cov batch yuav tsum tau ua li ntawd thaum lub sij hawm lub sij hawm no nws twb tag hnav tawm. Feem ntau, stucco yog npaj nyob rau hauv ib lub thoob los ntawm nyob rau hauv lub dej-xim. Yuav kom tsim xws li ib tug muaj peev xwm (tsis tiav) yuav ua tau cia li feeb ntawm 20. Hniav plaster (uas noj yog ib nyuag me dua cov plaster thiab xis mas), feem ntau hom kuj solidifies es sai sai. Yog li ntawd, koj yuav tsum npaj nws nyob rau hauv me me.

Maas plaster tsis solidify hauv ob teev. Yog li ntawd, thaum uas siv cov xws cuab yeej ntawm ib zaug tau npaj ib theej loj feem (feem ntau yog 10-15 litres muaj peev xwm, nyob rau hauv cov kev tshwm sim hais tias ua hauj lwm yog ua los ntawm ib tug neeg).

xam txoj kev

Mus saib uas txheej thickness yuav tsum nyob rau saum npoo ntawm pre-staking phab ntsa yuav tsum tau ua, i.e. mus xyuas lawv sib txawv los ntawm ib tug dav hlau.

Lub txhaws yuav txiav txim siv ib tug ntsuj plig theem thiab plumb. Lub sib txawv yuav tsum tau ntsuas nyob rau hauv ib tug ob peb tswj cov ntsiab lus. Yuav ua li cas yuav muaj ntau, lub zoo dua. Tom ntej no, cov kev tshwm sim summed thiab muab faib los ntawm tus xov tooj ntawm cov ntsiab lus. Yog li ntawd nws yog ua tau rau kawm yuav tsum tau tuab. Paub qhov plaster tau ib quadrant 'meter', ua suav txoj cai npaum li cas ntawm cov ntaub ntawv uas yuav tsum yooj yim.

Muab xam los piv txwv li:

Suppose muab koj muaj tau txiav txim hais tias tus dab tsi thaiv phab ntsa yog 50 mm thiab qhov hloov tus nqi nyob rau hauv ob lub ntsiab lus 30 thiab 10 hli. Quav tau 50 + 30 + 10 = 90 hli. Faib los ntawm tus xov tooj ntawm cov ntsiab lus 90/3 = 30 mm. Ntawd ces yog lub txheej thickness yuav tsum tsis tsawg tshaj li 3 cm. Cov nqi ndlwg 1m2 plasters nyob rau hauv rooj plaub no nws yog ua los ntawm gypsum yog, raws li peb pom 9 kg. Thiaj li, rau ib tug txheej ntawm 3 cm nws xav tau 9h3 = 27 kg. Maas - feem 16h3 = 48 kg. Cov uas ua tus xov tooj yog multiplied los ntawm cov tag nrho cheeb tsam ntawm cov phab ntsa. Piv txwv li, nyob rau hauv ib chav tsev nrog 6x4 m 2.5 m qab nthab siab thaj tsam ntawm lub ob ntev phab ntsa yog sib npaug zos 15 + 15 = 30 m ^2, ob tug luv luv - 10 + 10 = 20 ^m2. Lub cheeb tsam ntawm ib tug qab nthab nyob rau hauv ib chav tsev - 6x4 = 24 m ^2. Cov no ib tug tag nrho cov xov tooj ntawm 50 + 24 = 74 ^m2. Uas yog tag nrho cov chaw ntawm cov gypsum plaster txheej 1 cm xav tau 74h9 = 666 kg. Maas plaster xav tau: 74h16 = 1184 kg.

Yuav ua li cas koj yuav tsum paub

Actual noj yog ib txwm ib tug sib tov ntawm ib tug me ntsis ntau muab xam. Plaster tej zaum yuav poob rau hauv pem teb thiab nyob twj ywm nyob rau hauv lub thawv rau nws thiab seev. Yog li ntawd nws yog tsim nyog los tau ib tug Tshuag ntawm cov ntaub ntawv uas (kwv yees li 5-10%). Muag plasters feem ntau nyob rau hauv lub hnab ntawm 30 kg. Thaum xam tus nqi ntawm lub rounding yuav tsum tau ua nyob rau hauv ib txoj kev loj. Uas yog, nyob rau hauv cov ntaub ntawv no, kev noj ntawm plaster yuav 666/30 = 22,2 sac. Thiaj li, qhov yuav tsum tau mus yuav ib tug 23 lub hnab. Xav paj tau paj - 24. Maas plaster xav tau 1184/30 = 39.5, piv txwv li 40-41 lub hnab.

Qhov tsawg kawg nkaus thickness ntawm lub beacons yog 6 hli. Ib tug thinner txheej yog ua li cas tsis muaj. Plaster nto ntseeg nkaws nyob rau hauv cov ntaub ntawv no tsis muaj tus muaj ib tug tej yam kev yuav tsis zoo li. Yog li ntawd, thaum ib tug neeg sab nraud tag phab ntsa txheej yog tsawg tshaj li 6 hli yog tsis tshua muaj tau. Lub tsuas kos yog MAAs-txiv qaub plaster, uas (los ntawm txau) yog feem ntau luas lub phab ntsa ntawm kev chav.

Yog hais tias koj nkim sij hawm nyob rau hauv ib qho kev ywj ua hauj lwm ntawm suav koj tsis xav tau, koj muaj peev xwm siv tau ib qho hauv internet tswvyim. Tag nrho cov uas yuav tsum tau yuav tsum tau ua nyob rau hauv cov ntaub ntawv no - yog ib daim teb yuav tsum tau ntaus qhov yuav tsum tau tus xov tooj (qhov ntev thiab dav ntawm phab ntsa, txheej thickness, thiab lwm yam).
