Application
Inoshandiswa murabha yechisikigo uye latex yakadai se styrene-butadiene, nitrile-butadiene, cis-butyl, polyisoprene, nezvimwewo, inogona kuita kuti ive yakanaka ye-multi-flex resistance uye anti-cracking performance.Kuvandudza kusimba kwesimba, kuwedzera dziviriro kubva kune zvinokuvadza simbi senge inopisa okisijeni, ozone uye manganese pamadziro emhangura, uye haina pesvedzero pavulcanization.Yakasanganiswa ne antioxidant D, inogona kugadzirisa akasiyana matambudziko ekuchembera erima rabha zvigadzirwa.Mukuwedzera, inoshandiswawo se polyethylene uye polypropylene.Inoshandiswa se antioxidant muindasitiri yerabha

Nzira yekugadzira: Hydroquinone inobatwa neaniline pasi pe catalysis ye triethyl phosphate pa 280-300 ℃ uye 0.7MPa kumanikidzwa kweimwe nguva.Chemicalbook inobvisa iyo yakawandisa aniline pasi peyakadzika vacuum uye yobva yanyungudutsa yepakati pasi pepamusoro vacuum.Zvinhu zvakasara mushure mekudirirwa kwepakati zvakachekwa, zviputi uye zvakaputirwa sechigadzirwa chakapedzwa.Iyo synthesis reaction ndeyekutevera
