Nto tha xim yog qhov yooj yim tshaj plaws thiab pheej yig tshaj plaws los tiv thaiv cov qauv thiab cov khoom tsim los ntawm kev cuam tshuam ib puag ncig. Nyob rau hauv lub sab hauv, staining muab ib tug harmonious saib thiab tsub kom lub durability ntawm ntoo pem teb, qhov rooj los yog lwm yam khoom ntawm tej khoom. Tam sim no, alkyd xim yog hom nrov tshaj plaws ntawm cov khoom siv pleev xim vim nws qhov zoo thiab muaj.
Hom alkyd xim los ntawm kev sib xyaw
Txhua cov xim yog ib qho kev sib xyaw ua ke uas muaj cov xim, cov hlua khi, cov kuab tshuaj thiab cov khoom siv pabcuam kom muaj txiaj ntsig ntxiv. Nyob rau hauv nws muaj pes tsawg leeg, alkyd xim kuj yog ib tug sib tov ntawm cov saum toj no Cheebtsam. Raws li hom binder tivthaiv, alkyd-raws li cov xim yog muab faib ua pawg hauv qab no: roj (lub binder yog cov roj qhuav zoo tib yam) thiab enamel (raws li alkyd varnishes).
Alkydno npavroj pleev xim - "MA", nws yog qhia nyob rau hauv lub txhab nyiaj. Thaum siv glyptal thiab pentaphthalic ziab roj hauv kev tsim cov xim muaj pes tsawg leeg, cov cim sib thooj "GF" thiab "PF" yog qhia rau ntawm lub kaus poom.
Txhua cov xim roj, suav nrog cov xim alkyd, muaj cov kua roj vanish me me. Cov txheej qhuav ntawm cov xim muaj pes tsawg leeg kuj tsis muaj zog rau cov neeg kho tshuab kev nyuaj siab. Cov xim zoo li no maj mam poob lawv qhov chaw.
Enamel xim muaj kev ua tau zoo dua. Namely:
- nrawm qhuav;
- tawm tsam cov tshuaj lom neeg ua phem;
- siab hnav tus nqi;
- sustainable.
Cov khoom siv feem ntau yog pentaphthalic (cim "PF"), tsawg dua - glyphthalic (kos "GF"). Lawv lub hauv paus yog alkyd-pentaphthalic thiab alkyd-glyphthalic kua roj vanish, feem. Lawv qhov tshwj xeeb muaj peev xwm yog dej tsis kam vim qhov tsim ntawm nyias nyias zaj duab xis muaj zog. Alkyd-urethane xim sawv tawm tshwj xeeb, uas yog qhov zoo tagnrho rau kev pleev xim hlau cov qauv raug rau ib puag ncig. Cov xim no npog qhov chaw ntawm cov kav dej, cov khoom siv hauv tsev, tsheb ciav hlau, thiab lwm yam. Nws kuj tseem tsim nyog rau kev pleev xim sab hauv - pleev xim rau radiators, cov kav dej, pob zeb thiab cib phab ntsa, cov qauv ntoo thiab cov khoom zoo nkauj.
Hom alkyd xim los ntawm lub hom phiaj
Txhua cov xim alkyd yog cov khoom lag luam uas ua raws li GOST cuam tshuam nrog kev kos. Nyob rau hauv ib lub kaus poom ntawm cov xim, ib tug code ntawm ob tsab ntawv thiab peb tus lej raug qhia. Cov tsiaj ntawv qhia txog hom xim tus neeg sawv cev los ntawm kev muaj pes tsawg leeg, thawj tus lej - cov peev txheej thiab lub hom phiaj, ob lub xeem - cov lej catalog. Kev txiav txim siab ntawm thawj tus lej los ntawm lub hom phiaj yog raws li hauv qab no:
- "0" - priming compounds;
- "1" - rau kev siv sab nraud nkaus xwb;
- "2" - siv rau hauv kev ua haujlwm sab hauv;
- "3" - cov xim xim ib ntus, siv lub ntsiab yog rau kev kos lossis sealing;
- "4" - cov xim tsis muaj dej tsis muaj dej;
- "5" - xim tshwj xeeb tsim los tiv thaiv cov khoom thiab cov qauv ntawm cov nas;
- "6" - cov khoom uas muaj zog tiv thaiv roj av thiab roj;
- "7" - tshuaj resistant xim;
- "8" - cov khoom lag luam uas muaj zog tiv thaiv tshav kub;
- "9" - pleev xim nrog hluav taws xob insulating zog.
YMatte enamel
Nws tshwm sim uas tsim kom muaj kev sib haum xeeb hauv sab hauv lossis siv qee cov tswv yim tsim, koj yuav tsum tsim kom muaj qhov matte. Cov xim tshwj xeeb alkyd tuaj yeem ua qhov no. Tsis tas li ntawd, nws muaj lwm yam muaj txiaj ntsig zoo: nws tiv taus qhov kub thiab txias hauv thaj tsam ntawm -50 txog +600 degrees Celsius, kev lag luam noj (nyob ntawm qhov zoo ntawm qhov chaw, kev noj yog los ntawm 80 mus rau 170 g / m2), nws tuaj yeem diluted nrog ib qho hnyav hnyavkuab tshuaj los yog dab dawb. Thiab ib qho zoo dua yog xim xim, tus nqi pheej yig rau yuav luag txhua tus neeg uas xav yuav nws.
tshuaj tsuag xim
Kev siv yooj yim thiab kev thauj mus los, alkyd xim yog tsim nyob rau hauv cov kaus poom aerosol. Lawv yooj yim siv, tsuas yog txau rau ntawm qhov chaw kom pleev xim. Tsis tas yuav tsum muaj txhuam los yog cov menyuam, nyias nyias thiab tshuaj tsuag rab phom. Rau kev pleev xim rau thaj tsam me me hauv qhov chaw uas muaj kev nkag tau yooj yim, cov kaus poom yog qhov tseem ceeb.
Alkyd xim lus qhia
Txawm hais tias xaiv txoj kev ntawm daim ntawv thov, muaj ib qho nuance uas yuav tsum tau coj mus rau hauv tus account. Qhov tseeb yog tias cov xim alkyd yog cov muaj pes tsawg leeg uas yuav tsis zais qhov tsis xws luag ntawm qhov chaw, tab sis tseem hais txog lawv. Yog li ntawd, nws yog ib qho tsim nyog yuav tau ua kom zoo meej theem ntawm qhov chaw ua ntej pleev xim, uas yog, puttying ua raws li kev sib tsoo.
Tam sim ntawd ua ntej siv txheej txheej xim, nws raug nquahu kom kho qhov chaw nrog primer. Qhov no yuav txhim kho qhov adhesion ntawm cov xim nws tus kheej rau saum npoo thiab muab lub zog ntxiv.
Yog tias cov xim alkyd thickened nyob rau hauv ib lub kaus poom, nws tuaj yeem diluted nrog dawb ntsuj plig los yog hnyav. Qhov ntim ntawm thinner yuav tsum tsis pub tshaj 10% ntawm cov xim ntim.
