Polyester Acrylate 5202B - Doorashada ugu Fiican ee Dahaadhka UV-ga ee Waxqabadka Sare leh
Resin acrylate polyester 5202B, waxaa loo arkaa resin aasaasi ah oo loogu talagalay codsiyada kala duwan ee UV-ga la daweyn karo, sida dahaarka UV, varnish-ka warqadda UV iyo daabacaadda flexo UV. Waxay leedahay dhowr faa'iido oo asaasi ah: daxal hoose, heer wanaagsan, dabacsanaan heer sare ah, duubis degdeg ah, dhegdheg sare, qoyn wanaagsan iyo awood dhalaal oo heer sare ah.
Polyester Acrylate 5202B waa resin UV oo tayo sare leh oo leh iswaafajin aad u wanaagsan oo la leh inta badan monomers-ka UV iyo resins-ka UV, taasoo ka dhigaysa mid ku habboon dahaarka UV ee kala duwan, varnish-yada warqadda UV, daabacaadda shaashadda UV, iyo waxyaabo kaloo badan. Waxay leedahay dahaar hoose, socod aad u fiican, dabacsanaan sare, sameynta filim degdeg ah, dhegdheg xooggan oo lagu dhejiyo noocyo badan oo substrate ah, sifooyin qoyn oo aad u fiican oo loogu talagalay midabyada iyo buuxinta, iyo ciid wanaagsan, taasoo ka dhigaysa agabka ugu habboon ee dahaarka heerka sare ah.
Marka hore, 5202B oo aan lahayn daxal iyo socod aad u fiican ayaa hubiya in si siman loo faafiyo inta lagu jiro codsiga, iyadoo la yareynayo cilladaha iyo hubinta dhammaystirka dahaarka aan cillad lahayn. Dabacsanaanteeda cajiibka ah waxay u oggolaanaysaa dahaarka inuu u adkeysto isbeddelka isagoon dillaacin, taasoo kor u qaadaysa cimriga iyo cimriga badeecada kama dambaysta ah.
Marka labaad, 5202B waxay si dhakhso ah u sameysaa filim adag, kaas oo hagaajiya hufnaanta wax soo saarka isla markaana buuxiya baahiyaha khadadka wax soo saarka xawaaraha sare leh. Intaa waxaa dheer, waxay muujisaa isku-dhejin aad u fiican oo ku xiran noocyo kala duwan oo substrate ah, taasoo hubinaysa isku-xidhnaan deggan oo waarta oo iska caabisa diirka.
Intaa waxaa dheer, sifooyinka qoyaanka ee 5202B ee ugu sarreeya waxay u oggolaanayaan inay si wax ku ool ah u dhex gasho midabyada iyo buuxinta, iyagoo hagaajinaya waxqabadka guud ee dahaarka iyo hubinta kala firdhinta isku midka ah. Awooddeeda ciidda ee aadka u fiican waxay ka dhigaysaa habaynta xigta mid siman, taasoo siinaysa fudeyd badan inta lagu jiro dhammaystirka dusha sare.
Polyester Acrylate 5202B waa doorashada ugu habboon ee lagu hagaajin karo tayada dahaarka UV, lagu hagaajin karo hufnaanta wax soo saarka, iyo lagu gaari karo waxqabad heer sare ah. Dooro 5202B si aad u hubiso in dahaarka UV-gaagu uu buuxiyo heerarka ugu sarreeya ee socodka, dhejinta, dabacsanaanta, iyo ciidda, taasoo keenaysa natiijooyin heer sare ah.
