Ipeyinti ye-enamel ye-acrylic
Ipeyinti ye-acrylic inokugcina ukukhanya okuhle kakhulu kunye nozinzo lombala, kwaye ngokubanzi ayithambekeli ekutyhelini. Ingakumbi xa isetyenziswa ngaphandle, ibonisa ukumelana okunamandla nokutyhelini. Oku kunxulumene ngokusondeleyo nenxalenye yayo ephambili, i-acrylic resin. Olu hlobo lwe-resin luneempawu zeekhemikhali ezizinzileyo kunye nokumelana okunamandla kwemozulu, kwaye lunokumelana ngempumelelo nokutyhelini okubangelwa yimisebe ye-ultraviolet kunye nokuguga kwe-thermal-oxygen. Nokuba ipeyinti ye-acrylic enamel ijika ibe tyheli kuxhomekeke kwifomyula ethile. Iimveliso eziqhelekileyo zinokutyhelini phantsi kwesenzo semitha ye-ultraviolet, kodwa iimveliso eziphuculweyo ezifana neentlobo ezisekelwe emanzini, ezo ziqulethe i-silicone resin okanye iintlobo eziguqulweyo ze-polyurethane zisebenza ngcono ngokuchasene nokutyhelini.
Imvelaphi yepeyinti
Ipeyinti ye-acrylic luhlobo lokwaleka olusebenzisa i-acrylic resin njengesixhobo esiphambili sokwenza ifilimu. Isetyenziswa kakhulu ekuhombiseni nasekukhuseleni iindawo ezifana neentsimbi, imithi, kunye nekhonkrithi. Ngenxa yokusetyenziswa kwayo rhoqo kwiindawo zangaphandle (ezifana neebhulorho, izixhobo zoomatshini, iinqanawa, njl.njl.), ineemfuno eziphezulu zokumelana nemozulu kunye nokugcina umbala. Nokuba ijika ibe tyheli yenye yezona zinto zibalulekileyo zokulinganisa umgangatho wayo wokusebenza.
Uhlalutyo lweempawu zokuxhathisa ipeyinti ye-acrylic
- Uzinzo lwesakhiwo seekhemikhali:
I-resin ye-acrylic ngokwayo ayinazo iibhondi ezimbini ezikwaziyo ukuxovwa okanye izakhiwo zeringi ezinuka kamnandi, ngoko ke ayichaphazeleki lula ziimpendulo ze-oxidation kunye nokutshintsha kombala xa ivezwa ekukhanyeni okanye emoyeni.
- Kukho iimveliso ezenzelwe ngokukodwa ukuthintela ukuba tyheli:
Abanye abavelisi baqalise ngokucacileyo iimveliso ze-"AC series without yellowing", nto leyo ebonisa ukuba eli shishini lenze uphuculo lobuchwephesha ukujongana nomba we-yellowing.
- Iifomyula ezisekelwe emanzini zinobuhlobo nokusingqongileyo kwaye zinokumelana ngcono nombala otyheli:
Ipeyinti ye-acrylic esekwe emanzini ine-VOC ephantsi. Ayipheleli nje ekubeni inobuhlobo nokusingqongileyo, kodwa ikwangenxa yokuba ayinazo izinto ezityheli ezifumaneka kwii-resin ezisekwe kwi-solvent, ayinakwenzeka ukuba ibe tyheli.
- Iimeko zokwakha kunye nokugcinwa kwazo zinefuthe:
Ukuba ivezwe kumaqondo obushushu aphezulu, ukufuma okuphezulu, okanye imisebe enamandla ye-ultraviolet ixesha elide, naluphi na uphahla lunokubonisa iimpawu zokwaluphala. Nangona kunjalo, ipeyinti ye-acrylic iyakwazi ukumelana nokutyheli xa ithelekiswa neepeyinti zemveli ze-alkyd, njl.
Indlela yokuphepha
Khetha iimveliso zepeyinti ye-acrylic enamel eziphawulwe ngo-"Yellow Resistance", "Ukusetyenziswa Ngaphandle Kuphela" okanye "Ezisekelwe Emanzini Ezinobuhlobo Nokusingqongileyo". Oku kunokunciphisa ngakumbi umngcipheko wokuba tyheli. Kwakhona, qinisekisa ukuba i-substrate icocekile kwaye yomile ngaphambi kokuba yakhiwe ukuze kuthintelwe ukuguga ngokukhawuleza ngenxa yokuvezwa ixesha elide kwiimeko ezimandundu. Kwiimfuno eziphezulu zokuhombisa (ezifana nezixhobo eziphezulu kunye nezithuthi), kuyacetyiswa ukusebenzisa ii-topcoats ze-acrylic ezomisa ngokukhawuleza ezinenxalenye enye. Ezi zinobunzima obuphezulu, iimpawu zokuhombisa ezilungileyo, kwaye azinawo amathuba okuba tyheli okanye zibe ngumgubo.
