Ārai Mate H CAS 74-31-7 Ārai Mate DPPD
Ingoa Pākehā:N, N-diphenyl-p-phenylenediamine
Whakarāpopototanga Ingarihi:DPPD
CAS RN:74-31-7
1. Ngā āhuatanga ā-tinana me te matū:
1.1 Tātai ngota: C18H16N2
1.2 Taumaha ngota: 260.34
1.3 Te taumaha motuhake: 1.2
1.4 Wairewatanga: Ka rewa ki te benzene, te ether me te acetone. Ka rewa paku ki te etanoru. Kāore e rewa ki te wai.
1.5 Te pūwāhi koropupū: 220-225℃, 0.5mmHg
1.6 Te pumau me te tauhohenga: Ka mura. Ina pāngia e te hau, e te rā rānei, ka waikura te hua, ka huri tōna tae. Ina pāngia e te waikawa hauwai wera, ka huri hei kakariki.
1.7 Ngā Āhuatanga: Ko te waikura o ngā matū rapa me te rapa e whakawhirinaki ana ki te momo pūmua e uru ana. Ko ngā raruraru ko ngā huringa tae kino, te ngaronga o te ngāwari, te ngaronga o te kaha kume me te hekenga o te ātete pānga, te koroheketanga, te ngatata me ētahi atu pirau o te mata. Ka whakaratohia e ngā antioxidants rapa te mahi me te tiaki nui i roto i ngā tono pēnei i te rapa me te kirihou, te tiaki i ngā pūmua mai i te pirau waikura nā te wera, te mārama, te memeha o te hau, ngā peroxides, te kutikuti, me ētahi atu āhuatanga hihiri. Ka whakaratohia e te antioxidant H DPPD te pumau wera me te pumau tae mō te wā roa; he whai hua i roto i te kiriata, te muka, me ngā tuhinga whakawhiti matotoru; ā, he pai te mahi i roto i ngā pūnaha kua whakakīia.

Ka taea te whakamahi i te antioxidant H/DPPD hei antioxidant i roto i te propellant totoka hei whakapai ake i te pumau o te rokiroki o te hua. Kua whakamahia mō ngā rapa taiao, styrene-butadiene, acrylonitrile-butadiene, butadiene, butyl, hydroxyl, polyisoprene kia whai hua ai pērā i te roa o te ora me te whakakaha hei whakarei ake i te modulus tensile, te whakapakari i te mahi tiaki ki te hāora wera, te ozone me ētahi konganuku kino pērā i te parahi, te manganese me te kore e pā ki te vulcanization o aua rapa. Ka taea e ia te whakatau i te raruraru koroheketanga kei roto i ngā hua rapa tae hohonu, i te wā e whakamahia ana te antioxidant H me te antioxidant D. Hei tāpiri, ka taea hoki te whakamahi hei stabilizer hāora wera mō ngā kirihou hangarau pērā i te polyethylene, polypropylene, polyamide, polyformaldehyde hei whakapai ake i tā rātou mahi ātete ki te āhuarangi.
Whakamahinga: 1) Ka whakamahia te matū ārai mate H/DPPD (N,N'-Diphenyl-p-phenylenediamine) hei matū ārai mate me te whakau mō te rapa, te hinu hinu me ngā kai. Ka whakamahia hoki hei aukati i te polymerization me te aukati i te pirau parahi. He matū takawaenga hei hanga tae, rongoā, kirihou, me ngā tāpiringa hopi horoi.
2) Ka whakamahia hoki te antioxidant H/DPPD i roto i te hanga o ngā polyolefins kua whakapūmautia kore tae me ngā kiriata PVC me PVB.
3) E whakamahia whānuitia ana te antioxidant H/DPPD i roto i te nuinga o ngā whatanga me ngā rapa taiao me ngā mea hangai.
Te tākai:Pēke whatu kua whakakikoruatia ki te pēke kirihou, ko te taumaha kupenga he 20 kg/pēke.
Rokiroki:Rongoāhia ki te wāhi hauhautanga, hauhautanga. Ko te roa o te oranga he 12 marama mai i te rā i hangaia ai. Kei te wātea tonu mēnā ka tika te hua o te whakamātautau anō i muri i te rā paunga.
Ngā tohutohu haumaru:Paitini. Me whakamahi ngā karapu rapa, te manawa me te tiaki kanohi i te wā e mahi ana mēnā ka pā ki te kiri, ki ngā kanohi rānei.
Te kawe waka:Āraia te ua, te pānga o te rā, me te pāmahana tiketike.
