Kuenzana kwemajasi, inozivikanwawo se flatness kana kufanana, indekisi yakakosha yekuyera kushongedza kwekuita kwejasi.National Standard GB1750-89 (79) inopa nzira dzakananga dzekutarisa nhanho.
Iyo pende inoputirwa kana kupfapfaidzwa pachigadziko cheplate ine nzvimbo yakadzika maererano neyakajairwa nzira yekugadzirira yepende firimu.Ipo bhurashi richivhura template, stopwatch inobatidzwa kuyera nguva inodiwa kuti bhurashi riite kuti chiratidzo chebhurashi chinyangarike uye kuumba firimu rakatsetseka, rinoratidzwa mumaminitsi.
Kupfapfaidza neiyi nzira iri pamusoro, tarisa iyo pendi yepasi kuti uwane yunifomu, yakatsetseka, isina kuunyana-isina nguva.Imwe nzira ndeyekugadzirisa sampu yependi kune viscosity yekushandisa, isa kumuenzaniso ine primer, ita kuti iite yakatsetseka uye kunyange, ipapo pakati pefirimu nebhurashi longitudinal bhurashi chiratidzo chebhurashi, tarisa kuti inguva yakadii brashi chiratidzo chinonyangarika. , iyo firimu inodzorerwa kunzvimbo yakatsetseka.
Kazhinji maererano nefirimu kuti isvike panzvimbo yakatsetseka yenguva yakatarwa: kwete kupfuura maminitsi gumi akanaka;Maminitsi gumi kusvika gumi nemashanu anokodzera;mushure memaminitsi gumi nemashanu haisi yunifomu haina kukodzera (isina-yekushongedza coating haigone kuita ichi chinodiwa)
Iko kuongororwa kwekuita kwekuenzanisa kune hukama hukuru nemhando dzakasiyana uye viscosity yezvipfeko.Iyo yekuyera kuita kwepamusoro viscosity coatings kazhinji yakaderera pane iyo yakaderera viscosity coatings.Nekuvandudzwa kwesainzi uye tekinoroji, mumakore achangopfuura, akawanda matsva ekuyeresa anoshandiswa zvishoma nezvishoma, akadai sePolyacrylic acid esters, iyo yakazara rheological pfuma uye yekuyera midziyo yejasi inogona kuvandudzwa zvakanyanya.
Iyo yakawanda iyo bhurashi mamakisi kana orenji peel inonyangarika, iyo inopfavisa iyo yekuvhara pamusoro, ndiko kuti, zviri nani kuita kwekushongedza.Iyo yekuyeresa kuita kwejasi inoenderana nekuumbwa uye chikamu che resin, pigment uye solvent, uye zvakare kune nzira yekushandisa.
