ChiiAntimony Trioxidekushandiswa?
Antimony Trioxideinonyanya kushandiswa pamwe chete nemamwe macommunication kupa murazvo unodzora zvivakwa. Chishandiso chikuru chakaita seflame retardant synergist musanganiswa nehalogenated zvinhu. Iko kusanganiswa kwemahalides uye antimony ndiko kunokosha kune chiito chemoto-retardant kune mapolymers, zvichibatsira kuumba hutu hunopisa zvishoma. Zvinhu zvinodzosa moto zvakadaro zvinowanikwa mumidziyo yemagetsi, machira, matehwe, uye machira.Antimony (III) Oxidezvakare iri opacifying mumiriri wemagirazi, ceramics uye enamels. Iyo inobatsira inobatsira mukugadzirwa kwepolyethylene terephthalate (PET plastiki) uye vulcanization yerabha.
