Gypsum self-leveling pem teb yog lub tsev qhuav sib xyaw, uas, ntxiv rau cov khoom siv hauv paus, suav nrog quartz xuab zeb thiab tshwj xeeb plasticizing additives uas ua rau kom cov plasticity ntawm cov tshuaj. Cov txheej tiav lawm muaj kev kho siab ceev. Yog li ntawd, txhua txoj haujlwm nchuav yuav tsum ua kom tiav hauv lub sijhawm luv kom hauv pem teb khaws nws cov yam ntxwv ua haujlwm tau ntev.
Cov khoom thiab cov yam ntxwv tseem ceeb
Qhov txawv ntawm tus kheej-leveling pem teb thiab lwm hom screeds yog tias lawv xav tau kev npaj zoo heev ntawm lub hauv paus. Nyob rau hauv lawv, cov ntaub ntawv waterproofing thiab insulating tsis tau nteg kom adhesion rau bearing nto tsis txo.
Lub pem teb tus kheej yog kim heev. Feem ntau nws yog nruab nrog ib txheej nyias ua ke nrog cov cement lossis gypsum. Qhov no yog ib qho kev xaiv pheej yig dua. Gypsum self-leveling pem teb yog pheej yig dua, raws li nwscov khoom yog suav hais tias kuj pheej yig. Tab sis nws qhov txawv feature yog lub siab ceev ntawm solidification.
Adhesion ntawm cov tshuaj rau lub hauv paus tshwm sim tom qab 5 feeb tom qab kev npaj cov tshuaj. Nws raug tso cai siv cov khoom siv rau 10 feeb yam tsis muaj qhov tsis zoo, thiab tom qab 20 feeb nws twb dhau los siv tsis tau. Yuav kom qeeb cov txheej txheem hardening me ntsis, ib qho kev daws ntawm borax yog ntxiv rau qhov sib tov.
Cov khoom xyaw ntawm gypsum self-leveling pem teb los ntawm cov tuam ntxhab sib txawv tsis muaj qhov sib txawv loj. Yog li ntawd, yuav tsis muaj cov lus pom zoo txog cov tuam txhab. Lub hauv paus ntawm kev sib tov yog gypsum thiab quartz xuab zeb.
Qhov zoo thiab qhov tsis zoo
Qhov tshwj xeeb tshwj xeeb thiab qhov txiaj ntsig tseem ceeb ntawm kev sib xyaw gypsum yog nws lub peev xwm xav paub. Ua ntej, nws absorbs noo noo, thiab tom qab ntawd muab nws tam sim ntawd, tswj qhov zoo ntawm cov av noo hauv chav. Lwm qhov zoo ntawm gypsum-based self-leveling pem teb muaj xws li cov hauv qab no:
- txheej txheej no kiag li sib xws thiab du. Nws hardens sai dua li cov cement-based screed, yog li qhov tshwm sim ntawm pob thiab tawg yog qhov tsawg.
- Cov khoom sib xyaw ua tiav sib npaug sib npaug ntawm lub hauv paus tiav.
- Gypsum txheej tswj cov av noo hauv chav, vim nws tsis tuaj yeem nqus dej ntau dhau, tab sis tseem muab nws tawm yog tias tsim nyog.
- Gypsum sib tov tuaj yeem nchuav tsis yog nrog kev pab ntawm cov tshuab tshwj xeeb, tab sis kuj manually.
Kuv muajgypsum muaj pes tsawg leeg thiab qee qhov tsis zoo. Txawm tias muaj tseeb tias nws tuaj yeem nqus dej noo, nws tsis tuaj yeem nqus dej ntau hauv chav. Los ntawm qhov no, nws yuav nrawm nrawm, yog li nws tsis pom zoo kom muab cov txheej txheem gypsum hauv chav dej thiab hauv chav ua noj. Lwm qhov tsis zoo yog tias gypsum screed yog incompatible nrog cov kua nplaum. Nws yuav tsum tsis txhob muab tso ua lub hauv paus rau hauv pem teb pobzeb.
Npaj lub hauv paus
Gypsum self-leveling pem teb yuav tsum tau qib siab zoo ntawm lub hauv paus. Muaj plaub txoj hauv kev los npaj ua ntej:
- Tiv tauj txheej. Txoj kev no muaj nyob rau hauv lub fact tias tom qab ib tug meej tu ntawm lub hauv paus, nws yuav tsum tau primed. Txhawm rau ua qhov no, raws li ib puag ncig ntawm cov phab ntsa, daim kab xev ntug yog nteg tawm thiab kho, thiab tom qab ntawd nws raug kho nrog primer mus rau qhov siab ntawm yav tom ntej tus kheej-leveling pem teb.
- Sau hauv pem teb nrog cov khoom sib cais. Hauv qhov no tsis tas yuav tsum muaj priming. Daim ntawv yog muab tso rau ntawm qhov chaw npaj (nws yuav tsum tau dov tawm tag nrho cheeb tsam). Cov khoom yog muag nyob rau hauv yob, nws yog tsim nyog los xam ua ntej npaum li cas nws yuav tsum tau rau tag nrho cov nto. Cov kab xev sib tshooj 10 centimeters.
- Tau tshwj xeeb cov khoom siv tiv thaiv dej. Cov txheej txheem kev teeb tsa zoo ib yam rau cov khoom siv sib cais, tab sis kev siv dej tsis zoo yog siv los ntawm daim ntawv. Nto priming tsis siv ntawm no.
- Pouring gypsum mix on the warm floor. Cov cua sov tsis ua mob rau cov muaj pes tsawg leeg, vim nws muaj kev tiv thaiv zoo rau qhov kub thiab txias.
Yuav tsum tau cuab yeej
Txhawm rau siv cov gypsum sib tov rau hauv pem teb, siv cov squeegee nrog cov ntawv hlau. Qhov no yog ib tug tshwj xeeb spatula nrog cov hniav uas sai sai tsim ib tug screed ntawm lub thickness yuav tsum tau.
Beacons yog siv los ua beacons uas pab saib xyuas qhov sib xws ntawm kev pabcuam. Nyob rau hauv ib qho kev daws, npuas tsim thaum muaj pes tsawg leeg yog tov nrog dej. Tom qab hardening ntawm xws li ib tug screed, pores yuav nyob twj ywm nyob rau hauv pem teb, uas yuav ua puas lub txheej thiab ua rau nws tsis muaj zog. Tshem cov npuas no tawm hauv pem teb nrog cov menyuam ntxaib.
Txhawm rau qib mortar rau hauv pem teb, koj yuav tsum taug kev ntawm nws hauv khau nrog studded soles (xim khau). Tsis txhob nqis mus rau hauv pem teb tseem ntub yam tsis muaj cov khau no, txwv tsis pub cov dents yuav ua rau saum npoo.
Txhawm rau tiv thaiv cov screed los ntawm kev tawg thaum nws qhuav, ib daim kab xev damper raug kho raws ib puag ncig ntawm phab ntsa. Tsis tas li ntawd, rau kev ua haujlwm koj yuav xav tau: ib theem, kev tsim khoom sib tov, primer, cov menyuam thiab lub thoob yas.
Npaj cov tshuaj thiab ua haujlwm
Tsis yog txhua leej txhua tus paub yuav ua li cas thiaj ua tau zoo hauv pem teb ntawm tus kheej. Rau kev ua haujlwm, nws yog ib qho tsim nyog los npaj cov hmoov qhuav qhuav thiab dej. Nws yog ib qho tseem ceeb kom soj ntsuam tag nrho cov proportions, txwv tsis pub lub txheej yuav tsis zoo. Ib qho kev sib xyaw kom zoo zoo li cov mis nyuj condensed hauv qhov sib xws. Tus nqi dej nyob ntawm seb muaj pes tsawg leeg xaiv.
Cov hmoov yog nchuav rau hauv dej ntawm chav tsev kub thiab nplawm kom huv si kom txog thaum cov khoom sib tov sib xyaw ua ke. Koj yuav tsum sib tov cov muaj pes tsawg leeg rau tsawg kawg 3feeb, ces cia nws sawv ntsug li 7 feeb thiab do dua.
Thaum cov tshuaj tau npaj tiav, nws yuav tsum ua tib zoo nchuav rau ntawm qhov chaw npaj thiab kis mus rau tag nrho cheeb tsam nrog tus kws kho mob hniav. Siv rab koob rau cov menyuam, qhov saum npoo yog ua tib zoo leveled thiab tso cai kom qhuav. Kev ua haujlwm tag nrho yog muab tsis pub dhau 30 feeb, txwv tsis pub cov gypsum-raws li cov khoom sib xyaw yuav tawv.
Tus kheej-leveling pem teb yuav tsum tau nchuav nrog kaw qhov rais thiab qhov rooj los tiv thaiv nws los ntawm cov ntawv sau. Tsis tas li ntawd, lub hnub ci ncaj qha yog qhov teeb meem rau nws, yog li nws yog qhov zoo dua los dai lub teeb curtains ntawm lub qhov rais. Kev ziab yuav tsum tshwm sim ib txwm, tsis txhob siv cov cua sov, qhov no yuav ua rau tawg ntawm qhov chaw.
Tsis yog lub luag haujlwm kawg hauv kev npaj txheej txheej yog cov lus nug ntawm ntau npaum li cas gypsum self-leveling pem teb dries. Cov kws tshaj lij tsis pom zoo kom nthuav tawm qhov chaw no mus rau lub nra ua ntej tshaj tom qab 12 teev. Txhawm rau kom ntseeg tau ntau dua, nws yog qhov zoo dua tsis taug kev ntawm qhov chaw rau 24 teev.
Ua haujlwm tuaj yeem ua tiav ntawm nws tus kheej. Feem ntau ntawm ib lub pob muaj cov lus qhia rau kev npaj cov muaj pes tsawg leeg, tag nrho cov proportions kom meej meej spelled muaj. Yog tias koj muaj kev tsis ntseeg txog koj tus kheej lub peev xwm, nws yog qhov zoo dua los tso siab rau txoj haujlwm rau cov kws tshaj lij.
Pom zoo los ntawm cov kws tshaj lij
Ib qho muaj zog thiab txawm tias txheej yuav tau txais yog tias koj ua raws qee cov cai thaum lub sijhawm teeb tsa. Cov gypsum-raws li muaj pes tsawg leeg hardens sai, yog li nws raug pom zoo kom faib cov av hauv ib chav ntawm ntau tshaj 9 m² rau ntau theem. Txhua ntu yog sau ua ke. Lub uniformity ntawm cov khaubncaws sab nraud povtseg yog soj ntsuam siv ib theem.
Txhawm rau npaj cov tshuaj los ntawm kev sib xyaw ua ke, uas tuaj yeem yuav ntawm cov khw muag khoom kho vajtse, koj yuav tsum siv cov kais dej. Txoj haujlwm nchuav yog qhov zoo tshaj plaws hauv 20 feeb (hnub kawg yog 30 feeb).
Qhov kub hauv chav uas cov hauv av tau nchuav yuav tsum tsis txhob qis dua +5 ° C. Thaum ua haujlwm tag nrho, koj yuav tsum siv lub tshuab ua pa, tsom iav thiab hnab looj tes.
