Yog tias peb piv cov xim pleev xim dej nrog cov khoom sib xyaw raws li cov kuab tshuaj, ziab cov roj thiab cov kua roj vanish, thawj tus yeej hauv ntau yam teeb meem. Firstly, nws tsis muaj teeb meem volatile tebchaw uas yuav pab tau rau atmospheric pa phem. Qhov thib ob, xws li kev sib xyaw ua ke tsis tuaj yeem ua rau muaj kev fab tshuaj thiab ntau yam kab mob hauv tus neeg, uas yog qhov tseem ceeb heev hauv lub ntiaj teb niaj hnub no. Thib peb, nws yog qhov tsim nyog rau kev ua haujlwm sab hauv, thiab nws tuaj yeem nyuaj heev los xaiv qhov muaj pes tsawg leeg.
Cov lus piav qhia tsis muaj ntxhiab tsw tshwj xeeb, qhov no yog qhov tseem ceeb heev yog tias nws tsim nyog los kho qhov chaw nyob. Nws tsis muaj cov tshuaj tua hluav taws, yog li nws kuj yog fireproof, uas yog ib qho tseem ceeb rau cov tsev ntiav. Qhov no kuj ua rau nws zoo dua cov xim uas muaj cov kuab tshuaj organic. Tab sis txhawm rau xaiv cov khoom tshwj xeeb, koj yuav tsum xav txog ntau hom, nrog rau kev paub koj tus kheej nrog qhov zoo thiab qhov tsis zoo.
Kev piav qhia ntawm dej-acrylic formulations
Cov xim zoo li no tau noj hauv 150 g ib square meter. Qhov tsawg kawg nkaus tus nqi nce mus txog 120g ib m2. Daim duab no nyob ntawm cov khoom ntawm cov khoom ua tiav, uas tuaj yeem ntxhib lossis du. Kev noj haus yuav ntau dua yog tias qhov chaw nqus dej ntau heev.
Qee yam ntawm cov xim dej-acrylic yog siv rau hauv ib lub ntim ntawm 200 g ib square meter los ua kom hnav tsis kam. Cov yam ntxwv ntawm kev ua haujlwm ntawm cov txheej txheem no yog tswj los ntawm GOST 28196-89. Qhov kev faib ua feem ntawm cov khoom uas tsis yog-volatile, uas muaj xws li pab pawg thiab resins, ncav cuag 57% los ntawm qhov hnyav ntawm cov xim. Qib pH tuaj yeem nyob ze xoom lossis siab li 9.5, qhia tias muaj cov alkaline me ntsis.
Ntawm cov yam ntxwv ntawm cov xim dej-acrylic yog:
- coating durability;
- xim brightness;
- sijhawm teem sijhawm tsawg;
- tsis muaj ntxhiab tsw phem.
txheej tom ntej tuaj yeem siv tau hauv ib teev tom qab qhov dhau los. Raws li rau lub ci ci ntawm cov xim, nws tsis ploj txawm nyob rau hauv lub zog ntawm ultraviolet hluav taws xob. Yog tias koj xav yuav cov xim acrylic-raws li dej-raws li sab hauv, koj yuav tsum paub tsis yog nws cov yam ntxwv, tab sis kuj hais txog tus nqi. Tus nqi qis kawg yog 150 rubles. ib liter, thiab qhov siab tshaj plaws yog 1000 rubles. ib litre. Tus nqi cuam tshuam los ntawm hom kev paub thiab kev ua haujlwm. Qhov kim tshaj plaws yog cov tebchaw uas muaj xim saturation thiab durability.
YSilicone xim
dej pleev xim rauntoo tuaj yeem yog silicone. Cov khoom xyaw no muaj ntau yam zoo, suav nrog:
- zoo vapor permeability;
- siab elasticity;
- tus kheej tu vaj tse;
- versatility;
- durability.
Cov xim ntoo uas muaj dej yog ntxuav nws tus kheej thaum cov av nkag rau saum npoo, yog li nws ib txwm zoo li ntxim nyiam. Yog tias koj xav nkaum qhov tsis zoo txog li 2 hli hauv ib txheej, ces koj yuav tsum siv cov khoom siv silicone, vim nws muaj elasticity siab.
Cov xim dej no muaj ntau yam. Nws tuaj yeem siv rau yuav luag txhua yam khoom, txawm tias dhau cov xim qub. Lawv hom tsis muaj teeb meem. Tsob ntoo tsis poob nws lub peev xwm ua pa tom qab kho kom zoo nkauj nrog xws li kev sib xyaw. Cov txheej yog ruaj khov. Cov khoom sib xyaw yog kim heev, tab sis tus nqi yog ncaj ncees los ntawm ntau qhov zoo.
YEmulsion Phab Ntsa Paint
Yog tias koj tab tom nrhiav cov xim phab ntsa dej, koj yuav tsum xav txog cov xim emulsion, uas tau muab faib ua:
- polymer raws cov xim;
- dej-raws li formulations;
- dej-dispersion mix.
Txhua ntawm lawv yog diluted nrog dej thiab muaj ntau qhov zoo, xws li:
- hluav taws thiab tawg kev nyab xeeb;
- tsis muaj cov kuab tshuaj organic hauv qhov muaj pes tsawg leeg;
- non-toxic.
Cov txheej tiv thaiv alkalis. Xws li cov xim pleev xim dej kuj muaj nws qhov tsis zoo, lawv nyob hauv thaj tsam txwv tsis pub siv. Cov ntaub ntawv yuav tsum tsis txhob siv raulacquered nto thiab nplaum xim. Dej-raws li emulsions thiab dej-dispersion sib tov yog ib puag ncig zoo. Lawv tsis deprive saum npoo ntawm lub peev xwm ua pa. Cov khoom siv polymer ua rau cov txheej txheem tiv thaiv kev puas tsuaj, thiab tseem muab qhov ziab kom qhuav.
Dej-dispersion xim muaj cov yam ntxwv tsis muaj dej noo, tab sis cov xim pleev xim tuaj yeem ntxuav nrog dej. Lwm qhov sib txawv ntawm cov khoom sib xyaw no yog cov xim palette. Koj tuaj yeem xaiv cov xim pleev xim dej los ntawm ntau qhov ntxoov ntxoo, thaum cov xim dej dispersion feem ntau muaj xim dawb. Ob qho tib si yog tsim rau kev ua haujlwm tiav ntawm lub qab nthab, vim lawv ruaj khov thiab tsis hloov xim raws sijhawm. Cov khoom sib xyaw no yog siv rau cov chav qhuav, tab sis nyob rau hauv kev ua lag luam koj tuaj yeem nrhiav tau hom pwm uas tiv taus pwm, muaj cov yam ntxwv ntawm kev ya raws thiab zoo rau chav ua noj thiab chav dej.
paj pleev xim hauv qab
Thaum xaiv cov xim pleev xim rau lub qab nthab, koj yuav tsum xyuam xim rau cov khoom Finnish "Joker thiab Harmony", uas koj tuaj yeem muab lub ntsej muag zoo nkauj. Cov txheej yog resistant rau ntxuav. Ua tiav matte yog "Siro Mat Plus" thiab "Syroplast-2" los ntawm Tikkurila. Lawv raug ntxuav nrog ib daim ntaub ntub thiab ntxuav lub teeb. Matte Euro 7 Ceiling Paints withstands lub teeb txhuam, tab sis tsis haum rau siv chav dej.
Tikkurila muaj ntau hom xim chav ntub dej nrog cov khoom siv tshuaj tua kab mob. Rau cov chav nrog xws li tej yam kev mob yog tsim nyog"Remontti Yassia", "Luya" thiab "Euro 20". Tab sis kom ua tiav lub qab nthab hauv chav dej thiab chav ua noj, koj tuaj yeem xaiv Dulux Reallife Chav Ua Noj & Chav Dej.
Lwm cov tuam txhab muag khoom muag cov xim pleev xim rau cov qab nthab, ntawm lawv yuav tsum tau sau tseg:
- Beckers 3.
- "Bindo 3".
- YSupermatt.
Ntau yam xim dej-dispersion
Dej-dispersion compositions, nyob ntawm cov binder tivthaiv, tuaj yeem muab faib ua peb hom, uas txawv ntawm thaj chaw siv thiab cov khoom. Cov xim pleev xim dej zoo li no tuaj yeem ua raws li kev sib cais ntawm cov hauv qab no:
- polyvinyl acetate;
- Ybutadiene styrene;
- acrylic.
Cov binders no muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab kev xaiv yuav nyob ntawm seb cov khoom ntawm cov khoom txheej. Piv txwv li, cov xim dej dispersion yog tsim los ntawm polyvinyl acetate dispersion hu ua PVA. Cov tebchaw no yog qhov pheej yig tshaj plaws thiab muaj kev tiv thaiv tsis zoo rau cov dej noo. Qhov no ua rau cov kev txwv ntawm lawv siv. Cov xim pleev xim dej tuaj yeem siv rau cov qab nthab thiab phab ntsa hauv chav qhuav.
Yog tias cov dej-dispersion muaj pes tsawg leeg yog raws li butadiene-styrene, ces qhov zoo tshaj plaws yog dej tsis kam. Txawm li cas los xij, ib qho yuav tsum tsis txhob hnov qab txog qhov txwv lub teeb nrawm, qhov no ua rau thaj tsam ntawm kev siv tsis yog li ntawd. Cov xim zoo li no ennoble qhov chaw ntawm sab hauv, thiab lawv tsis siv sab nraud vim qhov pom ntawm yellowness thaumraug lub teeb.
Compound raws li acrylic dispersion
Yog tias cov dej sib tov yog raws li acrylic dispersion, ces koj yuav tau them nyiaj ntau dua rau cov xim, tsis zoo li hom yav dhau los. Tab sis cov tebchaw zoo li no muaj ntau yam thiab feem ntau siv. Lawv kuj tseem hu ua acrylate thiab khaws lawv cov xim nyob rau hauv txhua qhov raug, txawm tias muaj hluav taws xob ultraviolet.
Dej-raws li acrylic xim yog ceev kom qhuav, ruaj, washable, breathable thiab saj zawg zog. Cov sib tov muaj zoo adhesion thiab ua ib tug zoo kawg nkaus txawm txheej. Nws kaw qhov tawg me me txog li 0.5 hli hauv qhov loj.
dej-raws li casein thiab chalk xim
Thaum xaiv cov dej-raws li cov khoom siv rau kev kho cov rooj tog ntoo, koj yuav tsum xyuam xim rau casein thiab chalk compositions, uas paub nyob rau hauv cov teb chaws Europe, thiab niaj hnub no yog nrov nrog cov neeg siv khoom Lavxias. Nrog rau cov kev sib xyaw no, koj tuaj yeem tsim kom muaj lub ntsej muag zoo nkauj uas tso cai rau koj siv cov txheej txheem xim sib txawv.
Basic nta
Cov khoom siv yog ib puag ncig zoo, yog li nws yog qhov zoo rau kev ua haujlwm sab hauv. Nws yog raws li cov mis nyuj casein, thiab ntawm cov khoom xyaw yog cov khoom xyaw ntuj, uas yog:
- txuas yam;
- mis nyuj;
- porcelain.
kawg muab lub zog rau qhov sib xyaw.
In xaus
Yog kojpib kho cov hauj lwm, ces, zoo li feem ntau cov neeg siv khoom, koj yuav ntsib teeb meem ntawm kev xaiv xim. Cov neeg yuav khoom tab tom nrhiav rau qhov sib xyaw ua ke uas muaj kev nyab xeeb rau kev noj qab haus huv, zoo siab thiab ua haujlwm ntev. Tag nrho cov kev xav tau no tau ua tiav los ntawm cov xim dej thiab cov kua roj vanish. Lawv tau siv ntau tshaj plaws vim lawv qhov tshwj xeeb muaj pes tsawg leeg, uas sib xyaw ua ke hluav taws kub, kev phooj ywg ib puag ncig thiab zoo nkauj zoo nkauj.
