Synthetic resin ipolymer compound, iyo inogadzirwa nekubatanidza yakaderera molecular raw materials - monomers (senge ethylene, propylene, vinyl chloride, nezvimwewo) mu macromolecules kuburikidza ne polymerization.Nzira dzepolymerization dzinowanzo shandiswa mumaindasitiri dzinosanganisira kuwanda kwepolymerization, suspension polymerization, emulsion polymerization, solution polymerization, slurry polymerization, gas phase polymerization, nezvimwewo. Zvishandiso zvekugadzira resin zvinogadzirwa zvakawanda.Mumazuva ekutanga, ivo vainyanya kugadzira marasha etara uye calcium carbide calcium carbide.Iye zvino anonyanya kugadzira mafuta uye gasi zvigadzirwa, senge ethylene, propylene, benzene, formaldehyde uye urea.

Bulk polymerization inzira yekupolymerization umo mamonomers anogadzirwa pasi pechiito chevatangi kana kupisa, chiedza, uye nemwaranzi pasina kuwedzera mamwe midhiya.Chimiro ndechekuti chigadzirwa chakachena, hapana kupatsanurwa kwakaoma uye kucheneswa kunodiwa, kushanda kuri nyore, uye chiyero chekushandiswa kwemidziyo yekugadzira chakakwira.Inogona kuburitsa zvakananga zvigadzirwa zvemhando yepamusoro senge pombi uye mahwendefa, saka inonziwo block polymerization.Izvo zvisingabatsiri ndezvokuti viscosity yezvinhu zvinowedzera kuenderera mberi nekufambira mberi kwepolymerization reaction, kusanganiswa uye kutengesa kupisa kwakaoma, uye tembiricha ye reactor haisi nyore kudzora.Iyo yakawanda polymerization nzira inowanzoshandiswa mukugadzira resin senge polyadditional methyl acrylate (inowanzozivikanwa seplexiglass), polystyrene, yakaderera-density polyethylene, polypropylene, polyester uye polyamide.
kumisa polymerization
Suspension polymerization inoreva maitiro epolymerization umo monomer inoparadzirwa kuita madonhwe pasi pechiito chemechani inobvongodza kana vibration uye dispersant, uye inowanzo miswa mumvura, saka inonzi zvakare bead polymerization.Mamiriro acho ndeaya: kune mvura yakawanda mu reactor, viscosity yezvinhu zvakaderera, uye zviri nyore kutamisa kupisa uye kutonga;mushure me polymerization, inongoda chete kupfuura nekuparadzaniswa kwakapusa, kugeza, kuomeswa uye mamwe maitiro kuti uwane resin chigadzirwa, chinogona kushandiswa zvakananga kugadzira kuumba;chigadzirwa chacho chakachena, zvakaenzana.Izvo zvakashata ndezvekuti kugona kwekugadzira kweiyo reactor uye kuchena kwechigadzirwa hakuna kunaka seyakawanda nzira yepolymerization, uye nzira inoenderera haigone kushandiswa kugadzira.Suspension polymerization inoshandiswa zvakanyanya muindasitiri.
