Kugwiritsa ntchito
Amagwiritsidwa ntchito mu mphira wachilengedwe ndi latex monga styrene-butadiene, nitrile-butadiene, cis-butyl, polyisoprene, ndi zina zotero, zimatha kukhala ndi mphamvu zambiri zotsutsa komanso zotsutsana ndi kukwapula.Limbikitsani kulimba kwamphamvu, onjezerani chitetezo ku zitsulo zovulaza monga mpweya wotentha, ozoni ndi manganese pakhoma lamkuwa, ndipo musakhudze vulcanization.Kuphatikizidwa ndi antioxidant D, imatha kuthetsa mavuto osiyanasiyana okalamba a zinthu zakuda za rabara.Kuphatikiza apo, imagwiritsidwanso ntchito ngati polyethylene ndi polypropylene.Amagwiritsidwa ntchito ngati antioxidant mumakampani a rabara

Njira yopangira: Hydroquinone imayendetsedwa ndi aniline pansi pa catalysis ya triethyl phosphate pa 280-300 ℃ ndi 0.7MPa kuthamanga kwa nthawi inayake.Chemicalbook imachotsa aniline owonjezera pansi pa vacuum yotsika kenako amathira wapakatikati pansi pa vacuum yapamwamba.Zotsalira pambuyo distillation wa wapakatikati ndi sliced, ufa ndi mmatumba monga yomalizidwa mankhwala.The kaphatikizidwe anachita motere
