Maonekedwe: Mafuta amadzimadzi osawoneka bwino
Kusungunuka: Kusungunuka m'madzi, kusungunuka mu Mowa, etha ndi zosungunulira zina zambiri
Chiyambi cha malonda ndi mawonekedwe ake
Styrene, ndi organic pawiri, mankhwala chilinganizo ndi C8H8, electron wa vinilu ndi benzene mphete conjugate, insoluble m'madzi, sungunuka Mowa, efa ndi zina zosungunulira organic, ndi monomer yofunika ya kupanga utomoni, ion kuwombola utomoni ndi kupanga mphira.
ntchito
Ntchito yofunika kwambiri ndi monga mphira wopangira ndi pulasitiki monomer, yomwe imagwiritsidwa ntchito popanga mphira wa styrene butadiene, polystyrene, polystyrene thovu;Amagwiritsidwanso ntchito kupanga copolymerize ndi ma monomers ena kupanga mapulasitiki auinjiniya amitundu yosiyanasiyana.Monga ndi acrylonitrile, butadiene copolymer ABS resin, yomwe imagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zapakhomo ndi mafakitale;SAN copolymerized with acrylonitrile ndi utomoni womwe umalimbana ndi mphamvu komanso mtundu wowala.SBS copolymerized ndi butadiene ndi mtundu wa mphira wa thermoplastic, womwe umagwiritsidwa ntchito ngati polyvinyl chloride, polypropylene modifier.
Styrene zimagwiritsa ntchito kupanga styrene mndandanda utomoni ndi styrene BUTADIene mphira, ndi chimodzi mwa zipangizo kupanga ion kuwombola utomoni ndi mankhwala, kuwonjezera, styrene Angagwiritsidwenso ntchito mankhwala, utoto, mankhwala ndi mchere processing. ndi mafakitale ena.3. Kugwiritsa:
Kuti muchite bwino, tikulimbikitsidwa kuwonjezera pambuyo pa dilution.Kuchuluka kwa madzi ogwiritsidwa ntchito kumadalira kwambiri kachitidwe ka ntchito.Wogwiritsa adziwe kuchuluka kwabwino kwambiri poyesera asanagwiritse ntchito.s.
phukusi ndi transport
B. Izi angagwiritsidwe ntchito , 200KG, 1000KG mbiya pulasitiki.
C. Sungani chosindikizidwa mu malo ozizira, owuma ndi mpweya wokwanira m'nyumba.Zotengera ziyenera kutsekedwa mwamphamvu mukatha kugwiritsa ntchito chilichonse musanagwiritse ntchito.
D. Mankhwalawa ayenera kusindikizidwa bwino panthawi yoyendetsa kuti ateteze chinyezi, alkali wamphamvu ndi asidi, mvula ndi zonyansa zina kuti zisasakanike.
