Dosage
Maitiro ekushandisa: Sanganisa iyo optical brightener PF-3 mune yakasarudzwa plasticizer pa 0.03-0.1% yehuremu hwepurasitiki, uye woenderera mberi nehunyanzvi hwekugadzira mapurasitiki anoshandiswa.Cherechedza pano kuti inofanira kusanganiswa zvakanaka.
Fluorescent brightener PF-3 inogona kunyungudutswa neplasticizer yobva yanyungudutswa mukumiswa nemaromburu matatu kuita mai doro.Wobva wasimudzira PF-3 yepurasitiki yefluorescent whitening agent yakamiswa zvakafanana panguva yekugadziriswa, uye kuigadzira pane imwe tembiricha (nguva zvinoenderana nekupisa), kazhinji pa120.～150 ℃ kwemaminitsi makumi matatu, uye 180～190 ℃ kweinenge 1 miniti.Ndiko kuburitsa kuchena kwakanaka uye kupenya mhedzisiro.Kana kuti sanganisa marudzi ese ezvigadzirwa kutanga, wozopedzisira wowedzera PF inopenya, sanganisa zvakaenzana pa160 ℃ kwemaminitsi mashanu, wozokunguruka kuita chimiro.
