Application

1. Antioxidant 626 inonyanya kushandiswa mukugadzira uye kugadzirisa mapurasitiki akasiyana se polypropylene, polyethylene, ABS, polycarbonate fiber uye polyester resin. ,
2. Antioxidant 626 is a phosphite axiliary antioxidant ine low volatility, iyo inogona kunyatso kudzivirira polymer discoloration, kuderedza kuparara kwepolymer, uye kuvandudza resin kuramba gasi kupera. Iyo inonyanya kukodzera polyolefins uye olefin copolymers, polycarbonate, polyamide uye mamwe mapurasitiki einjiniya, pamwe nerabha, machira uye zvinonamira. Kuwedzerwa kwe antioxidant 626 kunogona kuvandudza zvakanyanya kugadzikana kwekugadzirisa kwezvinhu, uye inoshandiswa zvakanyanya mukugadzirisa kwe polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polystyrene, polyvinyl chloride uye mamwe thermoplastics uye elastomers. pakati. Uye zvakare, antioxidant 626 zvakare ine yakanakisa kudzivirira kwekushanduka kwemavara kunokonzerwa nechiedza uye kupisa, pamwe neimwe mwenje kudzikamisa mhedzisiro, iyo inogona kuvandudza mwenje, kugadzikana kwekupisa, simba remagetsi uye kugadzikana kwemavara echigadzirwa, nekudaro kuwedzera hupenyu hwechigadzirwa. chigadzirwa.
3. Antioxidant 626 ine makemikari akagadzikana ehupfumi uye kuenderana kwakanaka nemapolymer mazhinji. Iyo inoshanda phosphite yekubatsira antioxidant. Kushandiswa kwaro hakugoni kungovandudza kugadzikana kwekugadzirisa kwezvinhu, asiwo kunatsiridza chiedza, kugadzikana kwekupisa, simba remagetsi uye kugadzikana kwemavara ezvigadzirwa. Iyo yakakosha yekuwedzera inoshandiswa zvakanyanya muindasitiri yepurasitiki.
