He aha ke kūlana haʻahaʻa halogen no nā mīkina lima nitrile haʻahaʻa halogen a Lijiejing?

I kēia manawa, ʻaʻohe kūlana ʻoihana i hoʻokahi no ka ʻike halogen i loko o nā mīkina lima nitrile haʻahaʻa-halogen. ʻO nā ʻoihana like ʻole a me nā ʻāpana noi e kuhikuhi pinepine i nā paepae maʻamau: ＜900ppm: Ma nā ʻoihana hana maʻamau a me nā ʻoihana uila, ua manaʻo ʻia he ʻae ʻia ka ʻike halogen ma lalo o 900ppm. Hoʻokō kēia i nā koi o ka hapa nui o nā wahi hana pololei a hōʻemi pono i nā pilikia pala i nā ʻāpana uila. ＜500ppm: Hoʻolālā kūikawā kekahi mau lama, e like me Lixin, i nā mīkina lima nitrile haʻahaʻa-halogen 12-'īniha no ka hana ʻana i nā wafer 8-'īniha a me 12-'īniha, e kaohi ana i ka ʻike halogen ma lalo o kēia pae e hōʻemi hou aku i nā pilikia haumia no nā huahana koʻikoʻi loa. ＜50ppm: Mālama kekahi mau hiʻohiʻona kiʻekiʻe o nā Mīkina Lima Nitrile Haʻahaʻa-Halogen mai Lixin i ka ʻike halogen holoʻokoʻa (me ka fluorine, chlorine, bromine, a me ka iodine) ma lalo o 50ppm. ʻAʻole wale kēia e kūlike me nā lula kaiapuni koʻikoʻi akā hōʻike pū kekahi i kahi kūpaʻa ikaika i ka pale ʻana i ke kaiapuni hana a me ke olakino o ka mea hoʻohana. No nā ʻoihana kikoʻī a i ʻole nā ​​​​​​hana hana, paipai mākou e kūkākūkā i nā kikoʻī loea o ka ʻoihana pili, nā kūlana ʻoihana, a i ʻole e hana i nā hoʻāʻo ʻoihana e hōʻoia i nā koi kikoʻī. Hōʻoia kēia i ke koho ʻana o nā huahana pale kūpono.
