Mgbatị ozi emetụtara

1. Yiri antioxidant MB, ọ bụ nnu zinc nke a pụrụ iji mee ihe ozugbo na-enweghị ịka nká ma nwee mmetụta nke decomposing peroxides.Ngwaahịa a nwere ezigbo nguzogide okpomọkụ.Mgbe agwakọtara ya na imidazole na antioxidants ndị ọzọ, ọ nwere mmetụta nchebe megide mmebi ọla kọpa.Enwere ike iji ya dị ka ihe enyemaka thermosensitizer nke latex foam compound iji nweta ngwaahịa ụfụfụ na ọbụna ụfụfụ, nakwa dị ka onye na-ahụ maka gelling nke usoro latex.

2. Kedu ka esi eme ngwaahịa:

(1) Ịgbakwunye ihe ngwọta nnu zinc nke mmiri na-edozi mmiri na ngwọta mmiri nke nnu metal alkali nke 2-mercaptobenzimidazole maka mmeghachi omume;

(2) N'iji o-nitroaniline dị ka akụrụngwa, o-phenylenediamine na-emepụta site na mbelata, wee meghachi omume na carbon disulfide na ngwọta sodium hydroxide iji mepụta 2-mercaptobenzimidazole sodium.Mgbe emechara ya, a na-agbaze nnu sodium na mmiri, a na-agbakwunye zinc aluminide na ngwọta mmiri ya.

3.The decomposition point bụ elu karịa 270 ℃.
