Umgangatho weengubo, owaziwa ngokuba yi-flatness okanye ukufana, isalathisi esibalulekileyo sokulinganisa ukusebenza kokuhlobisa kweengubo.Umgangatho weSizwe we-GB1750-89 (79) ubonelela ngeendlela ezithile zokumisela umgangatho.
Ipeyinti ihlanjululwe okanye ifakwe kwi-plate yesiseko kunye nomgangatho osicaba ngokwendlela yokulungiselela ngokubanzi ifilimu yepeyinti.Ngelixa ibhrashi ivula itemplate, istopwotshi siyasebenza ukulinganisa ixesha elifunekayo ukuze ibrashi yenze uphawu lwebrashi lunyamalale kwaye lenze umphezulu wefilimu ogudileyo, obonakaliswa ngemizuzu.
Ukutshiza ngale ndlela ingentla, jonga umphezulu wepeyinti ukuze ufezekise ixesha elifanayo, eligudileyo, elingenamibimbi.Enye indlela kukulungelelanisa isampuli yepeyinti kwi-viscosity yesicelo, ifake kwisampuli nge-primer, yenza ukuba igudiswe kwaye ihambe, emva koko phakathi kwefilimu ngebrashi ye-brush longitudinal uphawu lwebrashi, jonga ukuba lingakanani ixesha lophawu lwebrashi lunyamalale. , ifilimu ibuyiselwa kwindawo egudileyo.
Ngokuqhelekileyo ngokwefilimu ukufikelela kwindawo egudileyo yokulinganisa ixesha: akukho ngaphezu kwemizuzu eyi-10 elungileyo;Imizuzu eyi-10 ukuya kwe-15 ifanelekile;emva kwemizuzu eyi-15 ayikho iyunifomu ayifanelekanga (i-non-decorative coating ayikwazi ukwenza le mfuneko)
Ukuvavanywa kokusebenza komgangatho kunobudlelwane obuhle kunye neentlobo ezahlukeneyo kunye ne-viscosity yeengubo.Ukusebenza komgangatho we-viscosity high coatings jikelele kuphantsi kunoko kuphantsi kwe-viscosity coatings.Ngophuhliso lwesayensi kunye netekhnoloji, kwiminyaka yakutshanje, izixhobo zokulinganisa ezintsha ziye zasetyenziswa ngokuthe ngcembe, njenge-Polyacrylic acid esters, ipropathi yerheological iyonke kunye nepropathi yokulinganisa yengubo inokuphuculwa kakhulu.
Okukhona amanqaku ebrashi okanye amaxolo e-orenji ayanyamalala, kokukhona kuthe tyaba indawo yokugquma, oko kukuthi, kokukhona kuphucuka ukusebenza kokuhombisa.Ukusebenza komgangatho weengubo kuhambelana nokubunjwa kunye nomlinganiselo we-resin, i-pigment kunye ne-solvent, kunye nendlela yesicelo.
