Muindasitiri yesilicone yekupupa furo, "platinum foaming" zvinoreva chirongwa chepamusoro chinoshandisa platinamu catalysts (platinum complexes) kukonzeresa kuchinjika-linking foaming reaction yesilicone.
2. "Platinum foaming" inorevei muindasitiri?
Kune vagadziri uye vashandisi vekupedzisira, "platinum foaming" inomiririra anotevera mapoinzi:
1. Kuchengetedzwa kwezvakatipoteredza uye kuita kwekuchengetedza kwakatanhamara, kusanhuhwirira uye kusiri-chepfu: Izvi ndizvo zvakanyanya kukosha kwayo. Nekuda kwekuti hapana kusarudzika ne-zvigadzirwa zvinogadzirwa, zvigadzirwa (zvakadai semidziyo yekubikira, zvigadzirwa zvevana, mapedhi embatya dzemukati, magasi ekurapa) hazvina kunhuwa kusingafadzi uye hazvina njodzi kumuviri wemunhu. Biocompatibility: Ichi chinhu chinoigonesa kupasa zvitupa zvekurapa nekudya (zvakadai seFDA, LFGB), zvichiita kuti ive sarudzo inofarirwa-yekupedzisira nzvimbo dzekunyorera.
. Kuchena kwepamusoro: Masero efuro akachena uye zvimiro zvemuviri zvakanyanya kugadzikana.
3. Zvido zvekugadzirwa kwepamusoro uye kusimba kwekutonga kwezvinhu: Sezvo platinum catalysts inowanzoita "poisoning" uye deactivation, zvose zvigadzirwa (raw raw, fillers, color pastes, etc.) panguva yekugadzira inofanira kuve "platinum"{2}}chaiyo", uye zvinhu zvine nitrogenur, kwete phosphorus inofanira kusanganiswa nezvimwe zvinhu zvakasanganiswa. Zvinodiwa zvehutsanana zvakanyanya zvinoiswa pamichina yekugadzira kudzivirira kutapukira-. Yakakwira tekinoroji chikumbaridzo: Yakanyanya kurongeka maitiro ekudzora uye nehunyanzvi ruzivo rwekugadzira inodiwa.
4. Mutengo wepamusoro: Platinamu isimbi inokosha, uye mutengo wekugadzirisa kwayo wakakwirira zvikuru kupfuura weperoxides. Izvi zvinoreva kuti zvigadzirwa zvesilicone zvakapushwa neplatinamu zvinowanzo kudhura.
