Synthetic utomoni ndi polima pawiri, amene amapangidwa ndi kaphatikizidwe otsika maselo zopangira - monomers (monga ethylene, propylene, vinilu kolorayidi, etc.) mu macromolecules mwa polymerization.Polymerization njira ambiri ntchito makampani monga chochuluka polymerization, kuyimitsidwa polymerization, emulsion polymerization, njira polymerization, slurry polymerization, mpweya gawo polymerization, etc. Zopangira kupanga utomoni kupanga ndi zambiri.M'masiku oyambirira, iwo anali makamaka mankhwala a malasha ndi calcium carbide calcium carbide.Tsopano ndi zinthu zambiri zamafuta ndi gasi, monga ethylene, propylene, benzene, formaldehyde ndi urea.

Bulk polymerization ndi njira yopangira ma polymerization momwe ma monomers amapangidwa ndi ma polymerized ndi oyambitsa kapena kutentha, kuwala, ndi ma radiation popanda kuwonjezera zina.Chikhalidwe chake ndi chakuti mankhwalawa ndi oyera, palibe kupatukana ndi kuyeretsedwa kovuta kumafunika, ntchitoyo ndi yosavuta, ndipo kugwiritsa ntchito zipangizo zopangira ndipamwamba.Imatha kupanga mwachindunji zinthu zapamwamba monga mapaipi ndi mbale, motero imatchedwanso block polymerization.The sangathe ndi mamasukidwe akayendedwe a zinthu ukuwonjezeka mosalekeza ndi kupita patsogolo kwa polymerization anachita, ndi kusanganikirana ndi kutentha kutengerapo n'zovuta, ndi kutentha kwa riyakitala n'kosavuta kulamulira.Njira yochuluka ya polymerization imagwiritsidwa ntchito popanga utomoni monga polyadditional methyl acrylate (yomwe imadziwika kuti plexiglass), polystyrene, polyethylene yotsika kwambiri, polypropylene, polyester ndi polyamide.
kuyimitsidwa polymerization
Kuyimitsidwa polymerization amatanthauza polymerization ndondomeko imene monoma omwazika mu m'malovu pansi zochita za makina oyambitsa kapena kugwedera ndi dispersant, ndipo kawirikawiri inaimitsidwa m'madzi, choncho amatchedwanso mkanda polymerization.Makhalidwewa ndi awa: pali madzi ambiri mu riyakitala, kukhuthala kwa zinthuzo kumakhala kochepa, ndipo n'kosavuta kusamutsa kutentha ndi kulamulira;pambuyo polima, zimangofunika kudutsa kupatukana kosavuta, kutsuka, kuyanika ndi njira zina kuti mupeze mankhwala a utomoni, omwe angagwiritsidwe ntchito mwachindunji pokonza;mankhwalawa ndi oyera, mofanana.The kuipa ndi kuti mphamvu yopanga riyakitala ndi chiyero cha mankhwala si zabwino monga chochuluka polymerization njira, ndi njira mosalekeza sangagwiritsidwe ntchito kupanga.Kuyimitsidwa polymerization chimagwiritsidwa ntchito makampani.
