The Zvinoumba zvicherwa nemidzimu. White mweya: mamirire

White mweya - rinokosha mumiririri (solvent), iro rinotarisirwa kuti sanganisa siyana chinowanika alkyds, mamwe rabha (zvakananga, zvinogona butyl uye cyclohexyl), uye polybutylmethacrylate. Uyezve, kana zviri mukati Kuronga kubatwa zvinhu epoxy esters, rinoita mweya uye anokwanisa Kuparadzwa nayo. Sei kushandisa chena mweya, sei kuzvishandisa, chii chinoitwa zvifambiswe uye chii kwese? Mhinduro yemibvunzo yose iyi uye vakawanda kudzidza mukufamba kuverenga nyaya ino.

zvoupenyu chikumbiro

Kazhinji, chena mweya solvent yaishandiswa sanganisa mafuta varnishes uye kuwana zvinhu akanyorwa yapfuura ndima. chokushandisa ichi chinoshandiswa kuti kubude degreasing uye kugeza pemvura, zvigadzirwa zvikamu nematurusi. zvamunokumbira -, "Itai chena mweya Degreases unhu." Akadaro solvent nokuda kwayo kuramba uye zvokurwa sezvamunoita, izvo tichakurukura gare gare, anokwanisa kuiparadza kunyange toughest zvinhu, saka kana iwe kushanda naye unofanira kutarisira dzimwe nzira yokudzivirira.

Asi shure application. Kuwedzera degreasing, mumwe mukuru zviri ichi mhando solvent ndiyo dilution gustotertyh uye kwakajairika pendi anotsanangura mafuta-, thickened enamel uye dzimwe mhando dzakawanda uye mhando pendi. Mukuwedzera, chena mweya anokwanisa Kuparadzwa paiva thickened primers, varnishes, bituminous zvinhu nevamwe. Uye kuti mugumisiro basa rinoitwa vaakaruramisawo zvavaitarisira, nyanzvi dzinokurudzira kugeza brushes uye rollers ari solvent kunyange vasati nokushandisa pavo alkyd, mafuta uye pentaphthalic enamels.
