Tiv thaiv qhov chaw los ntawm kev cuam tshuam tsis zoo, suav nrog cov huab cua, polyurethane enamel tau siv niaj hnub no, uas tau muab muag rau ntau yam. Qhov sib tov no yog ntau hom polymers nrog cov khoom tiv thaiv. Yog tias peb sib piv cov tshuaj no nrog lwm cov xim, ces tsis muaj lwm txoj kev xaiv tuaj yeem piv nrog polyurethane enamel. Feem ntau, cov khoom siv no yog siv los ua cov txheej txheem tiv thaiv, vim tias cov yeeb yaj kiab muaj kev nyab xeeb siab.
Kev faib tawm ntawm polyurethane enamels
Polyurethane sib tov yog cais raws li cov khoom yuav tsum tau coated, nrog rau hom kev thov thiab muaj pes tsawg leeg. Koj tuaj yeem siv txhuam los yog tshuaj tsuag aerosol tshwj xeeb rau daim ntawv thov. Qhov chaw ntawm kev siv polyurethane enamel yog dav heev, ntau hom tuaj yeem siv rau pob zeb, ntoo lossis hlau. Ua ntej siv cov sib tov polyurethane, ntoo tsis tas yuav tsum tau primed, nws tsuas yog yuav tsum tau qhuav kom zoo.
Technicalspecifications
One-component polyurethane enamel yog ib qho muaj pes tsawg leeg uas yog tsim los ntawm polyurethane, xim thiab hnyav. Ntawm cov yam ntxwv tseem ceeb ntawm qhov sib tov no yuav tsum tau hais txog:
- durability;
- elasticity;
- kev nyab xeeb tom qab hnyav evaporation;
- chemical stability.
Polyurethane tebchaw ua tau zoo kawg nkaus rau qhov nyuaj tshaj plaws.
Ntau yam ntawm polyurethane enamels
Polyurethane enamel tuaj yeem ua rau dej tawg. Ntawm qhov zoo yog tsis muaj teeb meem nyob rau theem ntawm staining thiab muaj peev xwm ntawm dilution nrog dej zoo tib yam. Nws tsis pom zoo kom pleev xim rau qhov chaw hydrophobic nrog cov enamels. Cov no suav nrog pob zeb, stainless hlau thiab yas.
Polyurethane yog sawv cev los ntawm kev hloov kho tshuaj lom neeg tshwj xeeb uas tso cai rau cov muaj pes tsawg leeg khaws cia ua cov dej tsis sib haum xeeb. Qhov no tso cai rau koj kom tau txais cov txheej txheem hnav-resistant. Yog tias tsim nyog los pleev xim rau hauv pem teb hauv chav tsim khoom, nws raug nquahu kom muab qhov nyiam rau qhov sib xyaw nrog cov kuab tshuaj organic.
YPolyurethane enamel ntawm cov kuab tshuaj organic
Polyurethane enamel tuaj yeem tsim los ntawm cov kuab tshuaj organic, xws li xylene lossis toluene. Rau dilution, nws yog qhov zoo dua los siv cov kuab tshuaj muaj ntawv tso cai uas tau pom zoo los ntawm cov chaw tsim khoom. Tom qab kho, uas yuav siv sij hawm ob hnub, xws li txheej acquiresCov khoom zoo uas yog hu ua qhov zoo tshaj plaws: hnav tsis kam, dej tsis kam, tsis kam mus rau ib puag ncig hnyav.
Polyurethane enamel xim kuj yog alkyd-urethane, lawv tau siv los tsim cov txheej elastic thiab ruaj khov uas ua rau qeeb qeeb thiab tseem muaj ntxhiab tsw qab thaum pleev xim. Tus nqi ntawm cov khoom sib xyaw no yog qis dua piv rau ib qho khoom siv urethane enamels.
Kev piav qhia ntawm ob lub ntsiab lus polyurethane enamels
Polyurethane ob-tivthaiv enamel muaj cov tawv tawv thiab cov enamel, thawj zaug ntxiv ua ntej siv. Qhov sib tov tseem siv tau rau 3 teev, thiab ziab yuav kav li 6 teev. Tus nqi ntawm cov khoom no yog siab, raws li yog lub zog ntawm txheej. Xws li polyurethane enamel rau hlau tuaj yeem siv rau cov qauv hlau uas yuav tsum tau thauj khoom raws li kev tsim khoom thiab ua haujlwm hauv cov khw kub nrog cov cua nruj heev.
Lub siab txwv ntawm kev ua haujlwm kub ntawm qhov sib tov no yog +80 ° C thiab tuaj yeem ncav cuag 100 ° C. Yog tias muaj kev xav tau los npog cov qauv uas yuav ua haujlwm nyob rau hauv cov xwm txheej kub ntxhov, yuav tsum tau yuav cov khoom tshwj xeeb. Piv txwv li, Polysteel pleev xim rau hlau, thaum raug kub, yuav tsim ib tug carbonaceous npuas uas ntseeg tau insulates thiab resists nplaim taws mus txog 1.5 teev.
Siv Elacor-PU polyurethane enamel
Yog tias koj xav tau primer-enamelpolyurethane, them sai sai rau Elakor-PU, tus nqi ntawm ib kilogram yog 275 rubles. Qhov no muaj pes tsawg leeg yuav tsum tau siv nyob rau hauv tej yam kev mob, uas yog qhia nyob rau hauv tsis muaj capillary sawv ntawm dej los ntawm hauv qab no. Nws tseem yog ib qho tseem ceeb uas lub hauv paus yog waterproofed. Residual deg noo noo yuav tsum tsis txhob ntau tshaj 5%. Ua ntej siv cov muaj pes tsawg leeg, qhov chaw tau tshem ntawm oily thaj chaw. Yog tias nws yog lub hauv paus pob zeb, ces nws yuav tsum tau xuab zeb nrog lub tshuab tshwj xeeb kom tshem tawm cov seem ntawm cov xim qub, av thiab cement laitance.
Ua ntej siv polyurethane enamel rau pob zeb, qhov saum npoo yuav tsum tau dedusted nrog lub tshuab nqus tsev, thiab tom qab ntawd coated nrog primer los ntawm tib lub chaw tsim khoom. Ua ntej siv, qhov sib tov zoo sib xyaw, thiab nws yuav tsum tau siv nrog polyamide cov menyuam hauv 4 txheej. Qhov tsawg kawg nkaus tus naj npawb ntawm cov khaubncaws sab nraud povtseg yog 2, tus lej kawg yuav nyob ntawm txoj haujlwm tau ua. Tos 4-8 teev ntawm cov tsho loj.
Kev siv cov enamel rau pob zeb "Elakor-PU Enamel-60"
Cov enamel no yog ib qho xim ntawm cov xim dej-kho ib nrab-gloss sib xyaw, qhov txiaj ntsig tseem ceeb ntawm uas yog qhov ua tau ntawm daim ntawv thov ntawm qhov kub thiab txias. Tom qab polymerization, hnav-resistant tawv polymer yog tsim rau ntawm qhov chaw, uas yuav chemically resistant.
Kev npaj muaj nyob rau hauv kev tu thiab priming lub nto, uas yog ces enamelled nrogkub ntawm -30 mus +25 ° C. Qhov kub ntawm cov khoom nws tus kheej tuaj yeem sib txawv ntawm +10 txog +25 ° C. Nws tseem yog ib qho tseem ceeb uas yuav tsum tau coj mus rau hauv tus account qhov txheeb ze av noo ntawm huab cua, nws yuav tsum tsis txhob ntau tshaj 80%. Ua ntej daim ntawv thov, cov muaj pes tsawg leeg yog tov kom txog thaum ib tug uniform xim thiab sib xws. Txhawm rau ua qhov no, koj tuaj yeem siv cov xim sib tov, uas tau teem rau qhov nrawm ntawm 400 txog 600 ib feeb.
Rau kev ua haujlwm, koj tuaj yeem siv cov chais lossis txhuam hniav uas tiv taus cov kuab tshuaj. Koj tuaj yeem siv cov tshuab tsis muaj cua tshuab. Ib txheej, uas nws cheeb tsam yog ib square meter, yuav siv li 150 g ntawm enamel. Qhov kawg tshwm sim yuav nyob ntawm qhov smoothness ntawm qhov chaw. Txheej ziab yuav siv sij hawm tib lub sij hawm raws li saum toj no.
Zaj lus
Yog tias koj txiav txim siab siv ob lub ntsiab lus polyurethane, koj yuav tsum tau coj mus rau hauv tus account tias nws daim ntawv thov tsis ua tiav rau ntawm qhov chaw ntub dej. Qhov kev xav tau no yog vim qhov tseeb tias lub hardener yuav ua rau cov kua tso tawm carbon dioxide, uas yuav ua rau lub ntsej muag ua npuas ncauj.
