Putty yog ib qho ntawm cov khoom nto moo tshaj plaws thiab feem ntau siv cov khoom tiav. Nrog nws cov kev pab, lawv ua nto leveling, priming, sealing seams thiab txawm tiav kho kom zoo nkauj. Cov tiam tshiab ntawm PVA-raws li putty radically txawv los ntawm yav dhau los compositions nyob rau hauv ib tug xov tooj ntawm kev ua hauj lwm tsis uas txiav txim qhov tshwj xeeb ntawm daim ntawv thov ntawm no txheej.
PVA yog dab tsi?
Cov cuab yeej no yog dav paub tias yog cov nplaum, tab sis nyob rau hauv kev sib raug zoo rau putty, peb yuav tsum tham txog ntau yam muaj pes tsawg leeg raws li polyvinyl acetate, diluted nrog tshwj xeeb additives. Tsis zoo li cov ntawv sau PVA, kev hloov kho kev tsim kho yog qhov txawv ntawm qhov muaj peev xwm ua kom muaj zog dua, lub zog thiab tsis kam rau sab nraud cuam tshuam. Raws li txoj cai, PVA-raws li putty ntawm hom no tau txhim kho ntau yamqhov zoo uas ua rau nws muaj peev xwm ua kom cov ntaub ntawv uas ntxhib thiab tsis zoo cuam tshuam nrog cov qauv txawv teb chaws. Cov nplaum muaj cov yas tshwj xeeb nrog cov thickeners thiab cov kuab tshuaj, nrog rau cov khoom siv ruaj khov, vim qhov tshwj xeeb, kev ntseeg tau ntawm kev tso cov mortar, nws cov dej tsis kam thiab teeb tsa nrawm tom qab thov.
Lub hom phiaj putty nrog PVA
Txawm hais tias qhov kev ua haujlwm ntawm kev sib txuas ob yam khoom txawv teb chaws yog pab rau cov pa roj hmab, qhov no nws yog qhov tseem ceeb. Kev ua tau zoo ntawm cov dej num xws li qib thiab priming ntawm cov pob zeb thiab cib yog siv tau zoo dua ua tsaug rau cov khoom sib khi. Lub hom phiaj ntawm polyvinyl acetate putty tseem yog kev kho kom zoo nkauj sab hauv ntawm qhov chaw uas tau npaj yuav tsum tau kho ntxiv nrog kev ntxuav dawb, pleev xim lossis lwm yam topcoats. Qhov tseem ceeb tshaj, qhov nce ntawm qhov ntsuas lub zog tso cai rau kev siv PVA-raws li putty rau hauv pem teb, nrog rau cov ntoo. Kev kho dua tshiab ntawm cov log tsheb thauj khoom lossis cov laug cam uas siv polyvinyl acetate tso cai rau koj los ua kom cov geometry ntawm cov flooring, nrog rau tshem tawm cov hnab ris ntawm kev puas tsuaj, tsis muaj kev hloov pauv ntawm cov txheej txheem. Lwm qhov yog tias nws yuav tsum yog ib qho tshwj xeeb ntawm cov nplaum nplaum nrog cov khoom ntxiv uas muab cov khoom siv roj ntsha rov ua dua tshiab.
Homemadeputty nrog PVA
Spackling cov neeg ua haujlwm niaj hnub no ua ntau yam haujlwm uas yuav tsum muaj kev sib xyaw tshwj xeeb ntawm cov khoom xyaw hauv cov khoom xyaw, uas lees paub qhov piv txwv zoo ib yam nrog cov ntoo ntxiv dag zog. Yog li ntawd, kev zam rau ib tus neeg cov zaub mov txawv ntawm cov khoom sib xyaw no kuj tau nthuav tawm nrog kev cia siab ntawm cov txheej txheem tshwj xeeb thiab, tib lub sijhawm, tsis suav nrog qhov tsis tsim nyog ntxiv. Tsis tas li ntawd, tsis txhob hnov qab tias npaj txhij-ua putty raws li PVA tsis pheej yig - txog 25-30 rubles / kg. Pom tseeb, cov tshuaj ua hauv tsev yuav raug nqi tsawg dua.
Yog li, koj tuaj yeem ua dab tsi nrog koj tus kheej txhais tes los ntawm polyvinyl acetate? Qhov kev xaiv yooj yim tshaj plaws yog ua ke PVA nrog chalk, uas yuav ua raws li kev muab tub lim. Hauv nws daim ntawv ntshiab, qhov kev sib xyaw ua ke no tuaj yeem siv los ua cov khoom tiav, thiab rau kev ua haujlwm ntxhib npog thaj chaw loj, nws yuav tsum tau diluted nrog sawdust lossis shavings. Lwm daim ntawv qhia yuav tsum ntxiv cov kua roj vanish rau cov dej-soluble saum toj no. Ib qho tshwj xeeb ntawm qhov sib tov no yuav ua kom elasticity ntau dua, uas yog qhov tsim nyog rau kev ua tiav qhov muag muag.
Npaj qhov chaw rau kev thov putty
Kev npaj tshwj xeeb yuav tsum tau ua ua ntej pib ua haujlwm. Cov no suav nrog kev tshem tawm cov teeb meem sib sib zog nqus nrog cov kab nrib pleb, dents thiab chips, abrasive tu cov plua plav thiab tshem tawm cov roj stains. Ntxiv mus, thaum pib nws yuav muaj txiaj ntsig zoo los daws qhov teeb meem ntawm qhov chaw nrog kev txheeb xyuasCov chaw tsis muaj zog uas tuaj yeem ua rau lub cev qhuav dej ntawm cov txheej qub nyob rau hauv kev cuam tshuam sab nraud. Kev kho dua tshiab ntawm cov qauv yog nqa tawm nrog cov cement-based plaster lossis primers tshwj xeeb. Nws tsis raug nquahu kom siv PVA-raws li putty rau cov haujlwm xws li, vim tias nws yog ib qho yooj yim thiab taw tes-raws li txhais tau tias ntawm kev npaj nto rau kev kho kom zoo nkauj ntxiv. Raws li cov tawv tawv greasy thiab oily stains, lawv muaj peev xwm daws tau nrog acetone, dawb ntsuj plig los yog lwm yam organic solvents.
siv cov txheej txheem
Cov cuab yeej ua haujlwm tseem ceeb yog spatula, thiab nws yuav pab tau kom muaj tus qauv dav thiab nqaim ntawm tes. Thawj zaug yuav pab ua kom tiav cov cheeb tsam loj, thiab qhov thib ob yuav pab txhawb kev patching ntawm qhov chaw puas. Cov txheej txheem rau kev thov PVA-raws li putty yog zoo ib yam li tso plaster, tab sis kho rau lub ntim me me. Tsis tas li ntawd, qhov loj yog faib rau tag nrho cov chaw ua haujlwm nrog kev txav tsis sib xws. Yog hais tias pob los yog dents tseem nyob, lawv yuav tsum tau ua kom tiav. Cov kab nrib pleb tshiab tau pom zoo kom muab ntim nrog rab phom mounting siv polyurethane ua npuas ncauj lossis sealant. Qhov zoo tshaj plaws putty txheej yog 0.5 hli. Nws yuav siv sijhawm li 24 teev los tsim kom muaj zog rau cov kauj ruam tom ntej ntawm qhov tuab no.
Khoom zoo
Qhov txiaj ntsig tseem ceeb ntawm putty nrog PVA kua nplaum suav nrog siabplasticity, versatility thiab ntau cov txiaj ntsig zoo uas tshwm sim thaum lub sijhawm ua haujlwm ntawm qhov tiav cladding. Cov khoom khaws cia cov qauv qub ntawm txheej, tsis succumbing rau abrasion thiab lwm yam mechanical influences. Raws li tau sau tseg hauv kev tshuaj xyuas ntawm PVA-raws li putty, kuj tseem muaj txiaj ntsig zoo rau plasterers. Tshwj xeeb, cov khoom tsis tau qias neeg, tsis hnov tsw thiab yooj yim haum rau hauv cov duab muab, tsis ua rau tsis yooj yim thaum faib cov huab hwm coj ntawm qhov chaw.
Khoom tsis zoo
Kev suav nrog polyvinyl acetate hauv cov khoom xyaw ntawm cov tshuaj pleev ib ce muab nws nrog ntau qhov tsis muaj zog. Cov no suav nrog cov hauv qab no:
- Kev txwv kev siv. Cov txheej txheem zoo li no tsis pom zoo siv rau hauv cov chav uas muaj cov av noo siab lossis nws tau npaj los nteg cov vuas.
- Lub sijhawm ziab kom qhuav. Raws li twb tau sau tseg lawm, PVA-raws li putty mus dhau lub sij hawm polymerization ntawm ib hnub, thaum cov txheej txheem ib txwm tuaj yeem qhuav hauv ob peb teev, uas txo lub sijhawm rau kev tsim cov haujlwm ua haujlwm.
- Cov kev xav tau siab rau kev npaj. PVA kua nplaum yog rhiab heev rau lub xeev ntawm qhov chaw uas nws tau thov. Yog li ntawd, nws yuav ua tau kom ua tiav siab adhesion tsuas yog tias lub hauv paus ua haujlwm raug ntxuav kom huv.
Zaj lus
Kev xyaum siv PVA kua nplaum hauv kev tsim kho thiab kev ua tiav tsis yog tshiab, tab sis ua ke nrogfilling thiab leveling mixs, nws pib siv dav tsuas yog ob peb xyoos dhau los. Lub sijhawm no, pawg tshwj xeeb ntawm cov khoom siv no tau tsim. Piv txwv li, PVA-raws li latex putty yog pom zoo tshwj xeeb tshaj yog rau sab hauv ilv ua hauj lwm, uas, nyob rau hauv particular, yog pom zoo raws li ib tug substrate rau xim thiab wallpaper. Yog tias qhov tseem ceeb ntawm kev tiv thaiv zoo ntawm cov phab ntsa, ces qhov kev nyiam yuav tsum tau muab rau acrylic nplaum putties, thiab rau kev siv sab nraum zoov muaj ib ntu tshwj xeeb ntawm facade sib tov raws li tib lub polyvinyl acetate. Los ntawm txoj kev, qhov zoo ntawm cov additives nrog PVA Cheebtsam yog tshwj xeeb tshaj yog pronounced nyob rau ntawm qhov chaw ntawm lub sab nrauv cladding ntawm lub tsev, qhov tseem ceeb yog muab tso rau ib tug nyuaj chaw ntawm coatings thiab zoo adhesion.
