Mhedzisiro yeZvinhu Zvitsva Zvinodzivirira Murazvo wePhosphorus-Nitrogen Pakuramba Kupisa Kwemachira
Nekuwedzera kweruzivo rwekuchengetedza, zvinhu zvisingatsvi moto zviri kushandiswa zvakanyanya mumaindasitiri akasiyana-siyana. Kunyanya muindasitiri yemachira, kusatsvinda kwemoto kwemachira kwakabatana zvakananga nekuchengetedzeka kwehupenyu nepfuma. Mumakore achangopfuura, zvinhu zvitsva zvinodzivisa moto zvephosphorus-nitrogen zvave nzvimbo inonyanya kutsvakurudzwa nekuda kwehunhu hwazvo hwakanaka hunodzivirira moto uye hushamwari hwezvakatipoteredza. Chinyorwa chino chinoongorora kukanganisa kwezvinodzivisa moto zvephosphorus-nitrogen pakudzivirira moto kwemachira kubva pamaonero akasiyana-siyana, zvichibatanidza zviyero zvechigadzirwa chakati uye data rekuyedza kuti zviongorore mashandiro azvo mukushandiswa kwazvinoita.
- Pfupiso yePhosphorus-Nitrogen Flame Retardants
1.1 Tsanangudzo uye Kurongwa kwePhosphorus-Nitrogen Flame Retardants
Zvidziviriro zvemoto zvePhosphorus-nitrogen imhando yemakomichi anosanganisira phosphorus nenitrogen sezvinhu zvinodzivirira moto. Zvichibva pachimiro chazvo chemakemikari, zvinogona kukamurwa kuita mapoka maviri makuru: zvinodzivirira moto zvephosphorus-nitrogen uye zvinodzivirira moto zvephosphorus-nitrogen. Zvinodzivirira moto zvephosphorus-nitrogen zvinosanganisira phosphates, phosphoramides, nezvimwewo, nepo zvinodzivirira moto zvephosphorus-nitrogen zvinosanganisira ammonium phosphate, ammonium polyphosphate, nezvimwewo.
1.2 Maitiro Ekudzivirira Murazvo ePhosphorus-Nitrogen
Maitiro ekudzivirira moto e phosphorus-nitrogen anodzivirira moto anosanganisira zvinhu zvinotevera:
• Kunonoka kwemurazvo wegesi: Zvinodzora murazvo zvePhosphorus-nitrogen zvinoora pakupisa kwakanyanya kuti zvigadzire phosphorus nenitrogen free radicals, izvo zvinogona kubata active free radicals panguva yekutsva, nokudaro zvichikanganisa combustion chain reaction.
• Kunonoka kwemurazvo wemoto: Zvinodzivisa murazvo wePhosphorus-nitrogen zvinoumba jira rakagadzikana panguva yekutsva, zvichiparadzanisa okisijeni nekupisa, uye zvichidzivirira kupararira kwemurazvo wemoto.
• Simba rekubatana: Zvinhu zvePhosphorus nenitrogen zvinoshanda pamwe chete panguva yekudzora moto, zvichivandudza kushanda zvakanaka.
