Mphamvu yoyambitsa: 30 Kcal / mol
Kutentha kwa theka la moyo wa maola 10: 73 ℃
Kutentha kwa ola la 1 theka la moyo: 92 ℃
Kutentha kwa mphindi imodzi ya theka la moyo: 131 ℃
Mpa ntchito:Amagwiritsidwa ntchito ngati monomer polymerization initiator wa PVC, unsaturated poliyesitala, polyacrylate, komanso ntchito ngati mtanda yolumikiza wothandizila polyethylene, ndipo ntchito ngati kuchiritsa wothandizila unsaturated poliyesitala utomoni, ntchito monga kuunika reagent, okosijeni ndi bleaching wothandizila; monga conditioner wa ufa ufa, ali bactericidal zotsatira ndi mphamvu makutidwe ndi okosijeni kwenikweni, zimathandiza ufa bleaching.
Kupaka:20 Kg, 25 Kg, thumba lamkati la PE, katoni yakunja kapena ndowa za makatoni, ndi pansi pa 35 ℃ zimasungidwa pamalo ozizira komanso olowera mpweya wabwino. Chidziwitso: Sungani phukusi losindikizidwa, kumbukirani kutaya madzi, ndikuyambitsa ngozi.
Zofunikira pamayendedwe:Benzoyl peroxide ndi gawo loyamba la oxidant organic. Nambala Yowopsa: 22004. Chidebecho chiyenera kulembedwa "organic peroxide" ndipo sichikhala ndi anthu.
Zowopsa Makhalidwe:Mu zinthu organic, kuchepetsa wothandizira, sulfure, phosphorous ndi lotseguka lawi, kuwala, zimakhudza, mkulu kutentha kuyaka; kuyaka kukondoweza utsi.
Njira zozimitsa moto:Pakayaka moto, motowo uzimitsidwa ndi madzi pamalo opondereza kuphulika. Pakakhala moto wozungulira mankhwalawa, sungani chidebecho kuti chizizizira ndi madzi. Pamoto waukulu, malo oyaka moto ayenera kuchotsedwa nthawi yomweyo. Ntchito yoyeretsa ndi kupulumutsa moto ukayaka sayenera kuchitika peroxide isanazimitsidwe. Ngati kutayikira komwe kumachitika chifukwa cha moto kapena kugwiritsidwa ntchito, kutayikirako kuyenera kusakanikirana ndi madzi onyowa vermiculite, kutsukidwa (popanda chitsulo kapena zida za fiber), ndikuyika mu chidebe chapulasitiki kuti muchiritsidwe mwachangu.
Njira zoyendetsera zinyalala zomwe tikulimbikitsidwa:Kukonzekera kumaphatikizapo kuwonongeka ndi natridium hydroxide. Pomaliza, mankhwala a sodium benzene (formate) osawonongeka amatsanuliridwa mukuda. Kuchuluka kwa njira yothetsera mankhwala kumafunika kusintha pH musanatulutse mu ngalande, kapena mutatha kusakaniza ndi nonfuel, kuti musapse. Zotengera zopanda kanthu za peroxide ziyenera kuwotchedwa chapatali kapena kutsukidwa ndi 10% NaOH solution.
