Cov xim tsis muaj ntxhiab tau nthuav tawm ntawm kev lag luam niaj hnub no ntawm lub tsev thiab cov khoom tiav hauv ntau yam. Cov emulsion yog kev daws teeb meem tawg, qhov twg cov yas, acrylic, polysiloxane thiab polyvinyl acetate cov khoom tuaj yeem ua tus khi.

Vim tias tsis muaj cov kuab tshuaj nyob hauv nws cov muaj pes tsawg leeg, cov xim tsis muaj ntxhiab, thiab tseem yog ib qho kev daws teeb meem zoo tshaj plaws rau kev pleev xim yam tsis muaj kev txwv tsis pub muaj menyuam yaus, cov neeg ua xua thiab cov neeg laus.

Nta thiab Cov txiaj ntsig

Cov ntxhiab tsw ntxhiab tsw nrov heev ntawm cov neeg siv khoom, vim tias lawv siv tau yooj yim, siv tau yooj yim thiab muaj tus lej tseem ceeb zoo:

Siab xim ceev pleev xim rau saum npoo. Cov xim pleev xim tiv taus qhov raug rau ultraviolet rays zoo, khaws qhov ci thiab xim xim thoob plaws nws tag nrho cov kev pab cuam lub neej.

• Los tiv thaiv plam … Cov xim pleev xim rau hauv pem teb hlau tsim cov nplais uas tsis plam, uas txo qhov kev pheej hmoo ntawm kev raug mob thiab tseem ua rau muaj kev nyab xeeb ntawm chav.
• Kom qhuav sai tso cai rau koj siv cov xim pleev xim tom qab 2 teev. Qhov no txo qis lub sijhawm rau kev ua haujlwm tiav, tso cai rau koj ua tiav kev kho dua tshiab hauv lub sijhawm luv.
• Kev nyab xeeb ib puag ncig thiab kev nyiam huv … Vim nws muaj pes tsawg leeg, cov xim tsis hnov tsw tsis muaj kev phom sij rau tib neeg thiab tsiaj.
• Kev tiv thaiv ya raws siab tso cai siv emulsions hauv chav nrog cov av noo siab.

• Kev nyab xeeb hluav taws … Qhov tsis muaj cov kuab tshuaj ua kom muaj kev tiv thaiv siab rau qhov hluav taws kub ntawm emulsion.
• Muaj cov tshuaj tiv thaiv corrosion ntxiv qee hom emulsions pab tiv thaiv cov hlau saum npoo av los ntawm qhov tsos thiab kis xeb.
• Yooj yim thov pleev xim rau cov hlau thiab ntxuav zoo los ntawm khaub ncaws, txhais tes thiab cuab yeej.
• Tus nqi dav dav tso cai rau koj xaiv cov emulsion ntawm tus nqi uas yooj yim rau txhua tus neeg siv khoom.

Ntau yam

Cov xim tsis muaj ntxhiab rau pleev xim rau xim hlau muaj nyob hauv ntau qhov loj. Kev sib xyaw sib txawv ntawm lawv tus kheej hauv kev sib xyaw, cov yam ntxwv tshwj xeeb thiab kev ua haujlwm. Los ntawm hom binder, emulsions muaj ntau hom.

Latex

Cov no yog cov kua nplaum uas ua los ntawm cov dej (paub zoo dua li "dej emulsion"). Cov khoom siv ntawm cov khoom siv hluavtaws, thaum qhuav, ua ke thiab tsim cov zaj duab xis nyias homogeneous. Qhov no tso cai rau koj los tsim ib txheej txawm tias ntawm cov xim pleev xim rau.

Hauv lawv cov kev ntxhib los mos, cov xim pleev xim yog matte, semi-matte, ci thiab ci zoo nkauj. Cov txheej txheem matte zoo npog lub hauv paus tsis xws luag, thiab cov uas ci ntsa iab xav tau kev npaj ntawm lub tiaj tiaj. Cov xim pleev xim tsis muaj tshuaj lom, tsis muaj ntxhiab, qhuav sai, muaj qhov hnav siab thiab tiv taus ya raws. Cov emulsion tsuas muaj nyob hauv dawb xwb. Nws tau siv ob qho tib si nrog kev siv xim thiab hauv nws daim ntawv dawb huv.

Acrylic

Cov no yog cov xim ziab kom qhuav uas tiv taus rau kev cuam tshuam ib puag ncig. Vim li no, emulsions tuaj yeem siv rau kev ua haujlwm sab hauv ob qho tib si hauv chav sov thiab txias.

Kev pleev xim cua sov cua sov, muaj qhov tshwj xeeb acrylic thermo enamel uas tuaj yeem tiv taus qhov kub thiab txias tau zoo, thaum tswj nws cov xim (yam tsis tawg).

Ua haujlwm tau nrog roj teeb kub … Hauv qhov no, cov xim yuav qhuav tag hauv ib teev. Thaum tha xim cov qauv hlau hauv chav tsis kub, koj yuav tsum ua tib zoo nyeem cov ntawv cim npe khoom, thiab tom qab ntawd yuav cov ntawv ua kom tiv taus te.

Roj

Hom txha hniav laus no yog ua los ntawm cov roj, ziab cov roj thiab cov xim xim. Cov khoom siv dav siv rau pleev xim rau xim hlau hauv chav sov thiab txias.

Cov xim muaj siab elasticity thiab kev pab them nqi, ua ib qho txawm thiab du nto thiab muaj tus nqi qis. Qhov tsis zoo ntawm cov roj pleev xim yog lub sijhawm qhuav ntev.

Alkyd

Cov xim Alkyd muaj qhov ua haujlwm siab tiv taus, ci thiab xim saturation, ntxiv rau qhov tsis muaj ntxhiab thiab ua haujlwm ntev. Cov hniav yog tsim rau pleev xim duab hluav taws xob thiab ua kom sov cov phuam ntsia hauv chav dej.

Cov alkyd nto tsis ntshai cov av noo thiab tiv taus tshuaj lom neeg. Qhov no ua rau nws muaj peev xwm pleev xim tso tsheb hlau luam rau roj thiab roj nplua nyeem thiab lwm yam kua dej ntawm cov tshuaj keeb kwm nrog cov xim zoo li no.

Ib yam zoo sib xws qhov sib tov yog te-resistant thiab muaj cov tshuaj tiv thaiv corrosion , ua tsaug uas nws tuaj yeem pleev xim tsis tsuas yog cov qauv hlau ntawm sab hauv, tab sis kuj yog rooj vag, laj kab thiab lwm yam khoom nyob ntawm txoj kev. Lub xub ntiag ntawm cov hluav taws kub retardants nyob rau hauv muaj pes tsawg leeg txo cov combustibility ntawm txha hniav laus, thiab muaj cov tshuaj tua kab mob tiv thaiv cov tsos ntawm pwm thiab mildew.

Pab Qhia

Nws yog qhov tsim nyog los pleev xim cov hlau ntawm qhov kub ntawm 10 txog 30 degrees, thiab huab cua huab cua yuav tsum tsis pub tshaj 75%. Ua ntej, saum npoo yuav tsum tau ntxuav ntawm hmoov av, degreased thiab qhuav. Tom qab ntawd koj yuav tsum tau thov cov tshuaj sib xyaw ua ke thiab tos kom txog thaum nws qhuav tag.

Kev siv cov primer tseem ceeb ua rau cov ntaub nplaum thiab muaj qhov cuam tshuam rau qib nruab nrab. Nws yog qhov zoo dua los siv cov tshuaj tiv thaiv xeb tshwj xeeb, uas tiv thaiv kev tsim cov xeb, thiab tseem tso tseg cov txheej txheem ntawm cov hlau puas hauv thaj chaw twb puas los ntawm xeb.

Cov cheeb tsam qhib thiab nkag tau yooj yim yog pleev xim nrog cov menyuam, thiab cov chaw uas nyuaj mus cuag cov txhuam. Kev siv cov xim hauv cov thooj voos kheej kheej yog qhov ua tau nrawm thiab siv cov emulsion siab, yog li ntawd, txhawm rau pleev xim rau thaj chaw loj, piv txwv li, qhov rooj rau tsheb, nws zoo dua los siv cov xim tha xim nrog cov menyuam thiab txhuam.

Chaw tsim tshuaj paus

Cov tuam txhab nto moo tshaj plaws uas tsim cov xim tsis muaj ntxhiab yog:

• Lus Askiv txhawj xeeb "Dulux".
• Ib lub tuam txhab los ntawm lub teb chaws Yelemees "Caparol".
• "Tikkurila" los ntawm Finland.

Cov khoom lag luam ntawm cov tuam txhab no tau paub dav thiab muaj qhov xav tau siab hauv kev lag luam hauv tsev thiab European. Ntawm cov tuam txhab Lavxias, ib tus tuaj yeem tawm ib lub lag luam " Lacra" Cov , koom nrog tsim cov xim thiab cov kua roj vanish rau 20 xyoo. Hom tshuaj no tsim cov xim muaj xim zoo ntawm tus nqi qis dua li cov neeg muaj npe txawv teb chaws.

Cov khoom lag luam ntawm Leningradskie Krasny lub tuam txhab, uas tsim cov emulsions ntawm txhua hom, tsis muaj qhov zoo dua, qhov tsos thiab cov yam ntxwv zoo rau xim los ntawm Tebchaws Europe.

Piv txwv ntawm kev siv

Cov xim tsis muaj ntxhiab tau kov yeej kev lag luam sai thiab yog cov khoom nrov thiab xav tau. Tsis qis dua hauv lawv cov yam ntxwv ua tau zoo rau cov hniav qub, lawv tso cai rau koj los tsim cov xim sib txuas ua ke thiab lav tau ua tiav kev nyab xeeb hauv kev siv.

Tsis muaj ntxhiab tsw, ziab kom qhuav thiab pleev xim rau xim zoo nkauj ua rau cov acrylic emulsion zoo tagnrho rau cov xim pleev xim

Xim sib xws nrog txhua lub phiaj xwm xim muab sijhawm zoo rau kev muaj tswv yim

Kev siv cov khoom sib xyaw alkyd rau pleev xim rau hauv pem teb lav qhov tsis plam saum npoo thiab qhov ntxim nyiam ntawm lub hauv paus
