Mhedzisiro yeNovel Phosphorus-Nitrogen Flame Retardants paMoto Resistance yeMicheka.
Nekuwedzera kwekuziva kwekuchengetedza, zvinhu zvinodzivirira moto zviri kushandiswa zvakanyanya mumaindasitiri akasiyana. Kunyanya muindasitiri yemachira, kushorwa kwemoto kwemachira kunoenderana zvakananga nekuchengetedzwa kwehupenyu nemidziyo. Mumakore achangopfuura, novel phosphorus-nitrogen flame retardants yave nzvimbo yekutsvagisa nekuda kweakanakisa-inodzoreredza murazvo zvivakwa uye hushamwari kwezvakatipoteredza. Ichi chinyorwa chinoongorora mabatiro ezvinoita phosphorus-nitrogen flame retardants pakuramba moto kwemachira kubva pamaonero akawanda, kusanganisa chaiwo zvigadzirwa paramita uye data rekuyedza kuongorora mashandiro avo mumashandisirwo anoshanda.
- Mhedziso yePhosphorus-Nitrogen Flame Retardants
1.1 Tsanangudzo uye Kurongeka kwePhosphorus-Nitrogen Flame Retardants
Phosphorus-nitrogen flame retardants ikirasi yemakomboni anonyanya kuumbwa nephosphorus nenitrogen sezvinhu zvinodzora moto. Zvichienderana nechimiro chavo chemakemikari, vanogona kukamurwa kuita mapoka maviri makuru: organic phosphorus-nitrogen retardants murazvo uye inorganic phosphorus-nitrogen retardants. Organic phosphorus-nitrogen flame retardants inonyanya kusanganisira phosphates, phosphoramides, nezvimwewo, nepo inorganic phosphorus-nitrogen flame retardants inosanganisira ammonium phosphate, ammonium polyphosphate, nezvimwe.
1.2 Nzira Inodzoreredza Murazvo wePhosphorus-Nitrogen Retardants
Iyo inodzoreredza murazvo we phosphorus-nitrogen murazvo retardants kunyanya inosanganisira zvinotevera zvinhu:
• Gas-phase flame retardancy: Phosphorus-nitrogen flame retardants inoora pakupisa kwepamusoro kuti ibudise phosphorus uye nitrogen free radicals, iyo inogona kubata inoshingaira mahara radicals panguva yekupisa, nekudaro ichikanganisa kutsva kweketani.
• Condensed-phase flame retardancy: Phosphorus-nitrogen flame retardants inoumba char layer yakagadzikana panguva yekupisa, inoisa iyo oxygen nekupisa, uye kudzivirira kupararira kwemurazvo.
• Synergistic effect: Phosphorus uye nitrogen elements zvinoshanda synergistically panguva yemoto-retardant process, kuvandudza kushanda zvakanaka.
- Hunhu hweNovel Phosphorus-Nitrogen Flame Retardants
2.1 Kushamwaridzana Nezvakatipoteredza
Novel phosphorus-nitrogen flame retardants haiburitse zvinhu zvine muchetura kana zvinokuvadza panguva yekugadzira uye kushandiswa, inosangana nezvinodiwa zvezvakatipoteredza. Semuenzaniso, ammonium polyphosphate (APP), yakajairwa inorganic phosphorus-nitrogen flame retardant, inoshandiswa zvakanyanya muindasitiri yemachira nekuda kwekuderera kwayo muchetura, halogen-isina, uye isina utsi.
2.2 Kunyatsogona
Novel phosphorus-nitrogen flame retardants inowana yakanakisa murazvo-retardant mhedzisiro pane yakaderera yekuwedzera mazinga. Ongororo dzinoratidza kuti kuwedzera 5% ammonium polyphosphate kunogona kuwedzera iyo inomisa oxygen index (LOI) yemachira kubva pa18% kusvika pamusoro pe28%.
2.3 Kugara kwenguva refu
Novel phosphorus-nitrogen flame retardants inoratidza kumira kwakanaka kwekugeza uye kuramba kwemamiriro ekunze. Kuita kwavo-kudzoreredza moto kunoramba kwakagadzikana kunyangwe mushure mekugezwa kwakawanda uye kuratidzwa kwenguva refu kune zvakasikwa nharaunda.

3.1 Kuderedza Oxygen Index (LOI)
Iyo inodzikamisa okisijeni indekisi ndiyo yakakosha metric yekuongorora iyo moto-inodzoreredza kuita kwezvinhu. Tafura 1 inonyora kukosha kweLOI yemachira akati wandei akajairika mushure mekuwedzera zvikamu zvakasiyana zvenovel phosphorus-nitrogen flame retardants.
| Fabric Type | LOI isina Retardant (%) | LOI ine 5% Retardant (%) | LOI ine 10% Retardant (%) |
| Cotton | 18 | 28 | 32 |
| Polyester | 20 | 30 | 34 |
| Nylon | 22 | 32 | 36 |
Sezvinoratidzwa muTebhurari 1, novel phosphorus-nitrogen flame retardants inogona kuwedzera zvakanyanya kukosha kweLOI yemachira, neLOI ichikwira sezvo huwandu hwekuwedzera hunowedzera.
3.2 Heat Release Rate (HRR)
Chiyero chekupisa chinoyera chiyero chinoburitswa kupisa panguva yekupisa. Mufananidzo 1 unoratidza HRR macurves emucheka wekotoni mushure mekuwedzera zvikamu zvakasiyana zvenovel phosphorus-nitrogen flame retardants.
Kubva kuMufananidzo 1, zvinogona kuonekwa kuti kuwedzera phosphorus-nitrogen flame retardants zvakanyanya kuderedza HRR yemucheka wekotoni, zvichiratidza kuderera kwekupisa kusunungurwa panguva yekupisa uye kuvandudza kushanda kwemoto-retardant.
3.3 Hutsi Density
Hutsi hwehutsi hunoyera huwandu hwehutsi hunogadzirwa panguva yekupisa. Tafura 2 inodonongodza hutsi hwehutsi hwemachira akati wandei akajairika mushure mekuwedzera zvikamu zvakasiyana zvenovel phosphorus-nitrogen flame retardants.
| Fabric Type | Hutsi Density isina Retardant (%) | Hutsi Density ine 5% Retardant (%) | Hutsi Density ine 10% Retardant (%) |
| Cotton | 80 | 60 | 50 |
| Polyester | 70 | 50 | 40 |
| Nylon | 60 | 40 | 30 |
Sezvinoratidzwa muTable 2, novel phosphorus-nitrogen retardants inogona kuderedza zvakanyanya hutsi hwemachira, kuderedza kugadzirwa kweutsi panguva yekupisa uye kuwedzera kuchengetedzwa.
- Kuita kweNovel Phosphorus-Nitrogen Flame Retardants muKushanda Zvishandiso
