Imikoreshereze y'ibicuruzwa
1.Tert-Butylhydroquinone ni antioxydants ikora neza. Mu biryo, tert-butylhydroquinone ikoreshwa nka antioxydeant yamavuta yimboga hamwe namavuta yinyamanswa ziribwa.
2.Mu musaruro winganda, tert-butyl hydroquinone irashobora gukoreshwa nka stabilisateur kugirango ibuze kwishyiriraho polymeriside kama.
3.TBHQ irashobora gukoreshwa nkikosora, ikabuza guhindagurika no kuzamura ituze. Mubyongeyeho, ikoreshwa kandi mu gusiga amarangi, amarangi hamwe na resin.
4.TBHQ ni antioxydants yamavuta iribwa kandi ikora neza, ibereye amavuta yimboga, lard, nibindi.
Ububiko nububiko
Ipaki:
25kg / ingoma ya karato cyangwa nkibisabwa.
Icyitonderwa: Ibigize imiti nubunini birashobora gutezimbere ibyifuzo byabakiriya
Ububiko:
Komeza ibikoresho bifunze neza ahantu humye kandi hafite umwuka mwiza.
Kurinda umutekano
Icyitonderwa cyo gufata neza umutekano
Gukorera ahantu hafite umwuka mwiza. Wambare imyenda ikingira. Irinde guhura n'uruhu n'amaso. Irinde gushiraho umukungugu na aerosole. Koresha ibikoresho bidacana. Irinde umuriro uterwa na electrostatike isohoka.
