MB S utomoni (Methylmetharylate-Butadiene-Sty-rene) ndi kumezanitsa copolymer wa TEB 3K (M), divinyl (B) ndi vinylbenzene (S), ali wapadera nucleocapsid structure.Be makamaka ntchito kusinthidwa PVC utomoni (PVC). pambuyo kusinthidwa osati kusintha makhalidwe ake kukokoloka-kukana, ndipo akhoza kusunga poyera choyambirira PVC.The MBS utomoni kuti kusinthidwa PVC amapangidwa zipangizo bwino mandala kapena zokongola pepala pepala zakuthupi, chubu ndi granulation botolo kuwomba, choncho, anati. MBS utomoni chimagwiritsidwa ntchito pvc chitoliro zakuthupi, pepala zinthu, pepala chuma, katundu zosiyanasiyana monga torsion filimu ndi bwino vial.Kuonjezera apo, utomoni wa MBS ungagwiritsidwenso ntchito PS ndi ABS utomoni wa retrofiting, kotero utomoni wa MBS ndi ndi osiyanasiyana ntchito monga mphamvu kusintha wothandizira wa polyvinyl kolorayidi utomoni.
Mu kupanga ndondomeko alipo MBS utomoni;Khalani kuti divinyl ndi vinylbenzene ikuchitika emulsification monga monoma m'madzi ndi emulsifying wothandizira;Pansi pa mwambo wa initiator, kuchita polymerization, kupanga styrene-butadiene latex (SBR latex), kuwonjezera TEB 3K ndi vinylbenzene kachiwiri ndi kuchita emulsion Ankalumikiza polymerization pambuyo gulu ndi 7: 3 chiŵerengero;Pezani MBS utomoni kumezanitsa latex (MBS utomoni latex);Kupyolera mukupeza ufa wa MBS mutatha kugwirizana, kutaya madzi m'thupi ndi kuyanika mankhwala, potsiriza, utomoni wa MBS wopangidwa mu teknoloji yomwe ilipo ndi kusintha kwa PVC kusasinthasintha ndi refractive index pa kumakhalanso kosakwanira;Komanso zomwe zili m'machitidwe omwe alipo, sizimawonjezera stablizer, komanso kuwongolera mawonekedwe amtundu wa PVC, pali cholakwika chowonekera pakugwiritsa ntchito wokhazikika yemwe ali.
Choncho, mtundu wa ntchito njira ya MBS utomoni amaperekedwa, ntchito kusintha PVC pepala zinthu utoto kuwala kuwala, kupewa pamwamba anafotokoza zophophonya zosiyanasiyana, kukhala vuto wofuna njira mwamsanga kwa wogulitsa dera.
