Intshayelelo

I-Antioxidant 4020, eyaziwa ngokuba yi-N-isopropyl-N'-phenyl-o-benzodiamine (IPPD), yinto eqhelekileyo esetyenziswa kwi-antioxidant. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-Antioxidant 4020:

 

Umgangatho:

- Imbonakalo: Kumhlophe ukuya kumdaka okhanyayo oqinileyo wekristale.

- Ukunyibilika: Inyibilika kwibenzene, ethanol, chloroform kunye neacetone, ukunyibilika kancinane kwi-benzene kunye nepetroleum ether, phantse ayinyibiliki emanzini.

- Ubunzima be-molecular: 268.38 g / mol.

 

Sebenzisa:

- I-Antioxidant 4020 isetyenziswa kakhulu njenge-antioxidant ye-rubber compounds, enokuthi isetyenziswe ngokubanzi kwiimveliso zerabha, amathayi, iityhubhu zeerubha, amashiti erabha kunye nezihlangu zerabha kunye namanye amashishini. Inokuphucula ukumelana nobushushu, ukuxhathisa kwe-oxidation kunye nokumelana nokuguga kweemveliso zerabha.

 

Indlela:

- I-Antioxidant 4020 idla ngokuphendula kunye ne-aniline kunye ne-isopropanol ukuvelisa i-isopropylphenol, kwaye emva koko ithatha indawo yokuphendula phakathi kwe-aniline kunye ne-styrene phambi kobukho bentsimbi okanye i-catalysts yobhedu ekugqibeleni ifumane i-N-isopropyl-N'-phenyl-o-benzodiamine (IPPD).

 

Ulwazi loKhuseleko: Nxiba iiglavu zokukhusela, iiglasi kunye nezixhobo zokukhusela zokuphefumla xa usetyenziswa.

-Kuphephe ukudibana nee-oxidants, iiasidi ezinamandla, iialkali ezinamandla, njl., ukuphepha ukuphendula okuyingozi.

- Ngexesha lokugcinwa kunye nokusetyenziswa, gcina kude kwimithombo yomlilo kunye namaqondo obushushu aphezulu ukukhusela umlilo kunye nokudubula.
