CAS RN:74-31-7
1. Zvenyama nemakemikari zvimiro:
1.1 Molecular formula: C18H16N2
1.2 Huremu hweMorecular: 260.34
1.3 Chaiyo giravhiti: 1.2
1.4 Solubility: Kunyungudika mubenzene, ether uye acetone. Dissolve zvishoma mu ethanol. Insoluble mumvura.
1.5 Poindi yekubikira: 220-225℃, 0.5mmHg
1.6 Kugadzikana uye reactivity: Inopisa. Kana ichinge yaburitswa kumhepo kana kuchiedza chezuva, chigadzirwa chinove neoxidized uye chinoshandura ruvara rwacho. Kana yabatwa neinopisa dilute hydrochloric acid, inova yakasvibira.
1.7 Properties: Iko oxidation yelatex uye rubber makomisheni zvinoenderana nerudzi rwepolymer inobatanidzwa. Matambudziko anosanganisira kushata kwekuchinja kwemavara, kurasikirwa nekushanduka-shanduka, kurasikirwa kwesimba rekusimba uye kuderedzwa kwemaitiro ekupikisa, kuchembera, kuputika uye kumwe kuparara kwepasi. Rubber antioxidants inopa kushanda kwakasimba uye dziviriro mumashandisirwo akadai serabha nemapurasitiki, kudzivirira mapolymer kubva mukuora kweoxidative nekuda kwekupisa, chiedza, kupera kwegasi, peroxides, shear, uye zvimwe zvinhu zvine simba. DPPD antioxidant H inopa yakakwirira-yenguva refu yekudziya kugadzikana uye kugadzikana kwemavara; inoshanda mufirimu, faibha, uye gobvu muchinjiko-chikamu zvinyorwa; uye inoita zvakanaka mumasisitimu akazadzwa.

Antioxidant H / DPPD inogona kushandiswa seyo antioxidant mune yakasimba propellant kuvandudza kugadzikana kwekuchengetedza kwechigadzirwa. Yakashandiswa kune izvo zvakasikwa, styrene-butadiene, acrylonitrile-butadiene, butadiene, butyl, hydroxyl, polyisoprene rabha kuti ive nekuita senge yakanaka flex hupenyu uye kushuva kwekusimudzira iyo tensile modulus, kusimbisa basa rekudzivirira kune inopisa-okisijeni, ozone. uye dzimwe simbi dzinokuvadza dzakadai semhangura, manganese isina pesvedzero pavulcanization yemarabha iwayo. Inogona kugadzirisa dambudziko rekuchembera riripo mune yakadzika-ruvara rubber zvigadzirwa nepo antioxidant H inoshandiswa pamwe chete ne antioxidant D. Uyezve, inogona zvakare kushandiswa seyakapisa-oxygen stabilizer kune ayo einjiniya mapurasitiki akadai se polyethylene, polypropylene, polyamide, polyformaldehyde kusvika. kunatsiridza mashandiro avo anodzivirira mamiriro ekunze.
Shandisa: 1) Antioxidant H / DPPD (N, N'-Diphenyl-p-phenylenediamine) inoshandiswa se antioxidant uye stabilizer yerabha, petroleum mafuta uye zvokudya. Inoshandiswawo sepolymerization inhibitor uye retardant kurwisa kuparara kwemhangura. Ikemikari yepakati kugadzira dhayi, zvinodhaka, mapurasitiki, uye detergent additives.
2) Antioxidant H/DPPD inoshandiswawo mukugadzirwa kwepololefins isina ruvara yakagadzikana pamwe nePVC nePVB mafirimu.
3) Antioxidant H / DPPD inoshandiswa zvakanyanya mumasikirwo mazhinji uye ekugadzira lattices uye rubber.
Packing:Bag rakarukwa rakaiswa bhegi repurasitiki, uremu hwemambure 20 kg/bhegi.
Kuchengeta: Kuchengetwa munzvimbo inotonhorera, ine mhepo. Hupenyu hwesherufu ndeyemwedzi gumi nemiviri mushure mezuva remugadziri. Ichiri kuwanikwa kana mhinduro yekuongororazve inokodzera mushure mekupera kwezuva
Mirayiridzo yekuchengetedza: Toxic. Magurovhosi eRubber, mweya wekufemerera uye kudzivirira maziso kunofanirwa kushandiswa panguva yekuvhiya kana kubatwa kweganda, kuonana kwemaziso..
Zvekufambisa:Dzivisa kunaya, kuratidzwa, kupisa kwakanyanya.
