Maonekedwe: madzi opaka mafuta owoneka bwino opanda mtundu
Kusungunuka: Kusungunuka m'madzi, kusungunuka mu ethanol, ether ndi zinthu zina zambiri zachilengedwe
Chiyambi cha malonda ndi zinthu zake
Styrene, ndi mankhwala achilengedwe, njira ya mankhwala ndi C8H8, elekitironi ya vinyl ndi benzene ring conjugate, yosasungunuka m'madzi, yosungunuka mu ethanol, ether ndi zinthu zina zachilengedwe, ndi monomer yofunika kwambiri ya utomoni wopangidwa, utomoni wosinthana wa ion ndi rabara wopangidwa.
gwiritsani ntchito
Chofunika kwambiri ndi kugwiritsa ntchito ngati mphira wopangidwa ndi pulasitiki, womwe umagwiritsidwa ntchito popanga mphira wa styrene butadiene, polystyrene, thovu la polystyrene; umagwiritsidwanso ntchito popanga copolymer ndi ma monomers ena kuti apange mapulasitiki opangidwa ndiukadaulo osiyanasiyana. Monga acrylonitrile, butadiene copolymer ABS resin, yomwe imagwiritsidwa ntchito kwambiri m'zida zosiyanasiyana zapakhomo ndi mafakitale; SAN copolymerized ndi acrylonitrile ndi resin yokhala ndi kukana kukhudza komanso mtundu wowala. SBS copolymerized ndi butadiene ndi mtundu wa mphira wa thermoplastic, womwe umagwiritsidwa ntchito kwambiri ngati polyvinyl chloride, polypropylene modifier.
Styrene imagwiritsidwa ntchito makamaka popanga utomoni wa styrene ndi styrene. Butadiene rabara ndi imodzi mwa zipangizo zopangira utomoni wosinthana ndi mankhwala a ion, kuphatikiza apo, styrene ingagwiritsidwenso ntchito mu mankhwala, utoto, mankhwala ophera tizilombo ndi mineral processing ndi mafakitale ena. 3. Kagwiritsidwe:
Kuti ntchito iyende bwino, tikukulimbikitsani kuwonjezera madzi mutasungunuka. Kuchuluka kwa madzi omwe agwiritsidwa ntchito kumadalira kwambiri makina ogwiritsira ntchito. Wogwiritsa ntchito ayenera kudziwa kuchuluka kwa madzi abwino pogwiritsa ntchito njira yoyesera asanagwiritse ntchito.
phukusi ndi mayendedwe
B. Chogulitsachi chingagwiritsidwe ntchito ndi mbiya ya pulasitiki ya ,200KG,1000KG.
C. Sungani yotsekedwa m'nyumba pamalo ozizira, ouma komanso opumira mpweya. Zidebe ziyenera kutsekedwa bwino mukatha kugwiritsa ntchito nthawi iliyonse musanagwiritse ntchito.
D. Chogulitsachi chiyenera kutsekedwa bwino panthawi yonyamula kuti chisasakanikirane ndi chinyezi, alkali ndi asidi wamphamvu, mvula ndi zinyalala zina.
