1. Hunhu hwemuviri nemakemikari:
1.1 Fomura yemamorekuru: C18H16N2
1.2 Kurema kwemamorekuru: 260.34
1.3 Simba guru remhepo: 1.2
1.4 Kunyunguduka: Nyunguduka mu benzene, ether uye acetone. Nyunguduka zvishoma mu ethanol. Hainyunguduke mumvura.
1.5 Pokufashaira: 220-225℃, 0.5mmHg
1.6 Kugadzikana uye kuita zvinhu zvitsva: Zvinobvira moto. Kana zvasangana nemhepo kana chiedza chezuva, chigadzirwa chacho chinopiswa uye chinochinja ruvara rwacho. Kana chasangana nehydrochloric acid inopisa, chinova chegirini.
1.7 Hunhu: Kuoxidation kwe latex ne rabha zvinoenderana nerudzi rwe polymer inosanganisirwa. Matambudziko anosanganisira kuchinja kwemavara, kurasikirwa nekuchinjika, kurasikirwa nesimba rekudhonza uye kudzikira kwekudzivirira, kukwegura, kutsemuka uye kumwe kuora kwepamusoro. Ma antioxidants erabha anopa mashandiro akakosha uye dziviriro mumashandisirwo akadai se rabha nemapurasitiki, anodzivirira ma polymer kubva mukuora kwe oxidative nekuda kwekupisa, chiedza, kupera kwegasi, peroxides, shear, nezvimwe zvinhu zvinochinja. DPPD antioxidant H inopa kugadzikana kwekupisa kwenguva refu uye kugadzikana kwemavara; inoshanda mufirimu, faibha, uye zvinhu zvakakora zve cross-section; uye inoshanda zvakanaka mumasisitimu akazara.

Antioxidant H/DPPD inogona kushandiswa se antioxidant mu solid propellant kuvandudza kugadzikana kwekuchengetedza kwechigadzirwa. Yakashandiswa kune rabha yemhando ye styrene-butadiene, acrylonitrile-butadiene, butadiene, butyl, hydroxyl, polyisoprene kuti ishande zvakanaka sehupenyu hwakanaka uye inofarira kusimudzira modulus yekudzora, kusimbisa basa rekudzivirira ku hot-oxygen, ozone nedzimwe simbi dzinokuvadza dzakadai semhangura, manganese pasina kukanganisa vulcanization yerabha idzodzo. Inogona kugadzirisa dambudziko rekukwegura riri muzvigadzirwa zverabha zvine ruvara rwakadzama ukuwo antioxidant H inoshandiswa pamwe chete ne antioxidant D. Uyezve, inogona kushandiswawo se hot-oxygen stabilizer kune mapurasitiki ekugadzira akadai se polyethylene, polypropylene, polyamide, polyformaldehyde kuvandudza mashandiro avo ekudzivirira mamiriro ekunze.
Mashandisirwo: 1) Antioxidant H/DPPD (N,N'-Diphenyl-p-phenylenediamine) inoshandiswa seantioxidant uye stabilizer yerabha, mafuta epetroleum uye zvekudya. Inoshandiswawo sepolymerization inhibitor uye retardant inhibitor inodzivirira kuora kwemhangura. Inoshandiswawo semakemikari anogadzira madhayi, mishonga, mapurasitiki, uye zvinowedzerwa zve detergent.
2) Antioxidant H/DPPD inoshandiswawo mukugadzira mapolyolefin asina ruvara akagadzikana pamwe nemafirimu ePVC nePVB.
3) Antioxidant H/DPPD inoshandiswa zvakanyanya muzvishandiso zvechisikigo uye zvekugadzira.
Kurongedza:Bhegi rakarukwa rakafukidzwa nebhegi repurasitiki, huremu hwaro hwe20 kg pabhegi.
Kuchengetera:Inochengetwa munzvimbo inotonhorera, ine mhepo inofefetera. Nguva yekushanda kwayo imwedzi gumi nemiviri kubva pazuva remugadziri. Ichiripo kana mhinduro yekuedzwazve ikaonekwa mushure mezuva rekupera.
Mirayiridzo yekuchengetedza:Chepfu. Magorovhosi erabha, respirator uye dziviriro yemaziso zvinofanirwa kushandiswa panguva yekuvhiyiwa kana ganda rakabatana, maziso akabatana.
Kutakura:Dzivisa mvura, kusvibiswa, kupisa kwakanyanya.
