Hoʻouna wikiwiki ʻia ka pauka DPPD CAS 74-31-7 Antioxidant H
Nā kikoʻī o ka Antioxidant H (DPPD) cas 74-31-7
ʻAi kapa Pelekane: N, N-diphenyl-p-phenylenediamine
Pōkole Pelekania: Antioxidant H DPPD
CAS: 74-31-7
ʻO ke ʻano molekole: C18H16N2
Kaumaha molekole: 260.34
Ka nui o ke kaumaha: 1.2
Ka hoʻohana ʻana o ka Antioxidant H (DPPD) cas 74-31-7
ʻO ka Antioxidant H DPPD kahi waiwai antioxidant ikaika o nā antioxidants amine, e like me nā antioxidants amine maʻamau, he hana pale ikaika ia i ka wela, ka oxygen, nā kumu ʻelemakule māmā, a he hopena pale maopopo hoʻi ia i ka ozone a me nā metala ʻino e like me ke keleawe, ka manganese ke kumu o ka ʻelemakule.
He hopena pale maikaʻi ko ka Antioxidant H DPPD i ka wela o ke kaiapuni, ka oxygen, ka mālamalama, ka ozone a me nā mea ʻē aʻe i loko o ka huahana, a he hopena maopopo kona i ka chloroprene rubber. Hoʻohana ʻia ka Antioxidant H DPPD i nā huahana rubber, ua hoʻomaikaʻi nui ʻia kona hana flexural a me ke kū'ē ʻana i ka māwae.
Hoʻohana nui ʻia ka Antioxidant H DPPD i nā ʻano huahana laholio ʻoihana like ʻole, kūpono loa no nā ʻano kaila kaʻa āpau, nā kaila mokokaikala, moped, hui ʻili kaila, hoʻohana pinepine ʻia ia i nā ʻano kāʻei āpau, kāʻei hoʻoili, kāʻei conveyor, a me nā mea ʻē aʻe, a me nā ʻano pad laholio like ʻole a me ke kaula a me ke kaula. Hoʻohana ʻia nō hoʻi ia no nā mea e pono ai i kēlā me kēia lā e like me nā ʻūpā.
ʻO ka Antioxidant H (DPPD) cas 74-31-7 Hoʻopili a me ka mālama ʻana
25kg no kēlā me kēia ʻeke, i hoʻopili ʻia i loko o ka ʻeke pepa i uhi ʻia me ka ʻeke palaki, pono e mālama ʻia i kahi anuanu a me ka ea. ʻO kona ola papa he 12 mau mahina. Ma hope o ka lā i kuhikuhi ʻia, inā kūlike ka nānā hou ʻana o ka huahana me ke kūlana maʻamau, hiki ke hoʻomau ʻia ka hoʻohana ʻana.
