Thaum ua tiav cov haujlwm tiav, nws tseem ceeb heev uas yuav tsum ua raws li thev naus laus zis. Raws li txoj cai dav dav, cov txheej txheem zoo nkauj yog siv rau saum npoo tom qab priming. Cov theem no yog qhov tseem ceeb heev, txij li kev noj thiab kev ua kom zoo ntawm cov khoom tiav yog nyob ntawm qhov tseeb ntawm nws qhov kev siv. Qhov zoo tshaj plaws muaj pes tsawg leeg rau saum npoo yog polyurethane primer. Xav txog nws cov yam ntxwv hauv kev nthuav dav.
Composition Benefits
Polyurethane primer yog suav tias yog ib qho khoom siv thoob ntiaj teb. Nws tuaj yeem siv los npaj cov substrates ntawm qhov sib txawv absorbency los ntawm ntau yam khoom siv. Zoo heev polyurethane primer rau pob zeb, hlau, ntoo, thiab lwm yam.
Cov muaj pes tsawg leeg tuaj yeem siv rau hauv pem teb sov. Lwm cov primer mixs yuav tsis muab qhov tsim nyog adhesion rau saum npoo.
Polyurethane primer sib npaug zoo rau kev siv sab hauv tsev thiab sab nraum zoov. Nyob rau tib lub sijhawm, kev noj cov tshuaj muaj pes tsawg leeg - tsis pub dhau 0.2-0.5 kg ib square meter. m. Nws yuav nyob ntawm qhov tob ntawm kev nqus. Kev noj cov primers feem ntau yog li 0.8-1 kg ib square meter. m.
Ib qho txiaj ntsig tseem ceeb yog qhov ua tau ntev ntawm cov txheej. Kev kho dua tshiab ntawm qhov chaw nrog polyurethane primer yuav tsis tas yuav sai sai. Compoundmuab kev tiv thaiv txhim khu kev qha.
Flaws
Polyurethane primer muaj ob peb qhov tsis zoo. Ua ntej ntawm tag nrho cov, lub txheej dries rau ib tug ntev lub sij hawm, txog 3-5 teev. Rau feem ntau primers, lub sij hawm no tsis pub tshaj 2 teev.
Ntxiv rau, tus nqi ntawm polyurethane muaj pes tsawg leeg yog siab heev. Txawm li cas los xij, cov kws tshaj lij paub tseeb tias nws tsis pom zoo kom txuag ntawm primer. Qhov pheej yig dua cov khoom xyaw, qhov sai dua nws yuav tsum tau hloov kho.
Ib feem sib xyaws
Cov khoom xyaw ntawm primer suav nrog polyurethane thiab ntau cov kuab tshuaj. Txawm li cas los xij, nyob ntawm cov khoom siv hauv paus, nws qhov chaw nyob (sab hauv lossis sab nraum chav), cov khoom tshwj xeeb yuav raug ntxiv rau qhov sib tov. Polyurethane primer tuaj yeem yog ib qho lossis ob qho.
Thawj cov khoom muaj cov ntsiab lus tseem ceeb thiab cov kuab tshuaj. Haum rau ib qho khoom siv polyurethane primer rau MDF, pob zeb phab ntsa, ntoo nto. Lawv pab txhawb lub substrate zoo, tso cai rau nws mus rau theem thiab txhim kho adhesion mus rau qhov kawg.
ob lub ntsiab lus
Lawv tuaj 2 lub fwj. Thawj muaj cov sib tov polyurethane, qhov thib ob muaj cov hardener. Cov ntsiab lus ntawm cov vials yog tov tam sim ntawd ua ntej daim ntawv thov rau saum npoo. Cov tshuaj no muaj zog heev. Txawm li cas los xij, nws tsis yooj yim dua vim tias nws muaj cov tawv tawv.
Ib qho ntawm ob qho kev sib xyaw ua ke feem ntau yog polyurethane primer "Elakor". Rau qhov noqhov sib tov yog zoo meej. Tshwj xeeb tshaj yog feem ntau nws yog siv rau pem teb nrog cov tsheb loj.
Yog tias muaj zinc-nplua nuj nyob rau hauv qhov sib tov, nws tuaj yeem siv rau cov hlau. Cov txheej txheem no yuav muab kev tiv thaiv txhim khu kev qha tiv thaiv corrosion.
Ob lub ntsiab lus polyurethane primer rau ntoo tsis tshua siv.
Hauv qee chav, priming yog tib txoj kev los pleev xim (piv txwv li, thaum ua tiav hauv pem teb ntawm lub rooj cob qhia lossis chaw nres tsheb). Hauv cov xwm txheej no, nws raug nquahu kom siv primer-enamel. Nws yuav ntxiv dag zog rau lub hauv paus thiab tiv thaiv nws ntawm kev puas tsuaj.
Kev faib tawm
Primer compositions yog:
- Acrylic. Lawv feem ntau yog ib qho. Xws li primers yog siv feem ntau rau kev kho mob ntawm MDF thiab ntoo nto. Vim lawv cov ductility, lawv nkag mus tob rau hauv cov khoom, sau cov pores thiab theem hauv paus. Cov khoom no tseem ceeb tshwj xeeb tshaj yog thaum siv rau cov uas tsis yog laminated MDF. Cov kev daws teeb meem acrylic kuj tseem siv tau zoo hauv kev kho cov pob zeb hauv tsev hauv tsev. Qhov txiaj ntsig tseem ceeb ntawm kev sib xyaw yog non-toxicity.
- Alkyd. Cov kev daws teeb meem no yog siv rau sab nrauv ntoo, MDF. Xws li cov ntaub ntawv ntseeg tau tiv thaiv cov khoom los ntawm kev puas tsuaj. Yog hais tias nws yog tsim nyog los hais txog qhov kev ntxhib los mos ntawm lub hauv paus, nws yog advisable siv primer-enamel. Nws tseem yuav yog lub tsho tiav.
- Epoxy. Xws li cov khoom sib tov yog siv feem ntau rau kev kho cov hlau nto.
Cov lus qhia rau kev xaiv
Txawm hais tias qhov tseeb tias cov tshuaj polyurethane yog universal thiab siv tau rau yuav luag txhua qhov chaw, koj yuav tsum xav txog:
- Qhov chaw ntawm qhov chaw. Qhov kev xaiv ntawm cov muaj pes tsawg leeg yog cuam tshuam los ntawm qhov chaw uas lub hauv paus nyob (sab nraum lossis hauv chav), dab tsi cuam tshuam rau nws (nag, cua, thiab lwm yam), cov av noo thiab kub.
- Ntawm cov khoom siv saum npoo. Nws yuav tsum nco ntsoov tias cov khoom sib tov haum rau ntoo lossis MDF yuav tsis ua raws li cov hlau puag.
- Sustainability. Rau kev kho kom zoo nkauj sab hauv tsev, nws yog ib qho tsim nyog yuav tau yuav cov khoom tsis muaj tshuaj lom. Nws raug nquahu kom xaiv cov khoom sib xyaw ntawm polyurethane nrog acrylic. Cov primers no zoo meej rau kev kho pob zeb thiab ntoo. Nws yog cov ntaub ntawv no feem ntau siv hauv kev tsim cov phab ntsa thiab cov plag tsev.
Tools
Cov thev naus laus zis rau kev kho cov hauv paus nrog polyurethane primers yuav luag zoo ib yam li siv rau lwm cov khoom xyaw. Qhov txawv yog tias cov qauv ntawm cov khoom sib xyaw no tsis haum rau daim ntawv thov los ntawm rab phom txau.
Koj tuaj yeem kho qhov chaw nrog polyurethane sib tov:
- Rollers ntawm ntau qhov sib txawv. Cov cuab yeej no tso cai rau koj los npog thaj tsam loj.
- Txiv. Lawv raug pom zoo kom siv los ua cov cuab yeej pabcuam. Piv txwv li, koj tsis tuaj yeem ua yam tsis muaj txhuam hniav thaum siv cov av mus rau qhov chaw nyuaj. Npog thaj tsam loj yuav siv sij hawm ntev.
kev npaj nto
Primer tuaj yeem yogsiv rau qhov tsis huv substrate. Txawm li cas los xij, kom zoo dua adhesion, qhov saum npoo yuav tsum yog:
- Ntxuav lub hauv paus los ntawm hmoov av thiab cov seem ntawm cov txheej dhau los.
- Rinse.
- Nyob thiab degrease.
Yog tias muaj qhov tawg loj ntawm qhov chaw, lawv yuav tsum tau kho. Cov kev tsis zoo me me tuaj yeem raug tso tseg vim qhov sib tov yuav ua rau lawv.
Txoj kev siv cov txheej txheem
Siv cov menyuam, cov tshuaj yuav tsum tau muab sib npaug ntawm qhov chaw.
txheej thib ob yog siv tom qab thawj zaug qhuav tag (tom qab 3-5 teev).
Nws raug nquahu kom ua haujlwm crosswise. Qhov no txhais tau hais tias yog thawj txheej tau thov vertically, ces lub thib ob lub sij hawm nto yog them nrog kab rov tav txav ntawm cov menyuam. Qhov no ua kom muaj kev sib haum xeeb ntawm kev sib xyaw rau hauv qhov chaw.
Txheej thib peb feem ntau tsis siv. Tom qab txheej thib ob tau qhuav lawm, kev ua tiav tiav pib.
Polyurethane primer "Elakor"
Cov khoom xyaw no muaj nyob hauv ntau hom. Qee cov primers siv cov khoom xyaw tshwj xeeb kom tau raws li ntau yam kev xav tau ua tiav.
Piv txwv li, polyurethane muaj pes tsawg leeg "Eco primer" yog siv los kho cov chaw uas niaj hnub sib cuag nrog dej haus thiab khoom noj. "Luxe primer" yog siv los ua kom tiav qhov chaw nrog pob tshab txheej. Nws tsis yog daj thiab tiv taus cov kab hluav taws xob ncaj qha.
Elacor primers kuj txawv nyob ntawm qhov xav tau qhov tob tob. Qhov tob tobCov muaj pes tsawg leeg, piv txwv li, yog siv los kho qhov ntxeem tau: polymer cement, magnesia concretes. Hauv qhov no, qhov sib tov tuaj yeem siv rau qhov chaw ntub dej (tsis ntub dej) pob zeb. Lub hauv paus tuaj yeem ua tiav rau hnub 10-12 tom qab nchuav.
Polyurethane primer roughly doubles nto zog.
