Imikhiqizo

Umkhiqizo ungakwazi ukuqalisa ngempumelelo i-polymerization ezingeni lokushisa eliphansi kanye nokugxila okuphansi ukuze ukhiqize i-polymer ephezulu yomugqa nephezulu yamangqamuzana.

Isiqalisi se-Va-044 sinokusebenza kahle kokuqalisa, isisindo samangqamuzana aphezulu kakhulu, ukuncibilika okuhle kwamanzi kanye nezinsalela ezincane.

I-VA-044 initiator itholakala ngokwethula amaqembu e-hydrophilic ku-molecule ye-azonitrile initiators, futhi inokunyibilika okuhle kwamanzi.Ngakho-ke, i-VA-044 initiator ngokuvamile ifanelekela i-aqueous solution polymerization kanye ne-emulsion polymerization ye-polymer synthesis.Uma kuqhathaniswa nezinhlobo ezijwayelekile zabaqalisi be-azo, isiqalisi se-VA-044 sinokusebenza kahle kokuqalisa, isisindo samangqamuzana aphakeme uma kuqhathaniswa, ukunyibilika kahle kwamanzi, kanye nomzimba oyinsalela omncane.Uma kuqhathaniswa ne-inorganic persulfate nezinye iziqalisi ezincibilika emanzini, isiqalisi se-VA-044 singakwazi ukwenza ukusabela kokubola okubushelelezi, okuzinzile nokulawulekayo ukuze kukhiqizwe ukulandelana okuphezulu kanye nama-polymers anesisindo samangqamuzana aphezulu.

Ngokungafani nemikhiqizo ye-azo nitrile, ngoba ayinawo amaqembu e-cyano, imikhiqizo yokubola ye-VA-044 initiator ayinabo ubuthi.Ngesikhathi esifanayo, ibola kancane kancane kunabanye abaqalisi, inezinga eliphezulu lokuguqulwa, futhi akukho zinsalela noma i-agglomeration eyenzekayo ngesikhathi senqubo ye-polymerization.Ingakwazi ukuqalisa ngempumelelo i-polymerization ekushiseni okuphansi kanye nokugxila okuphansi ukukhiqiza umugqa ophezulu kanye nama-polymers esisindo samangqamuzana aphezulu.Ngakho-ke, i-VA-044 initiator isetshenziswa kabanzi ku-polymerization ye-aqueous solution kanye ne-emulsion polymerization ye-polymer synthesis, njenge-monomer acrylamide polymerization, i-Initiator yokusabela kwe-polymerization efana ne-styrene emulsion polymerization kanye ne-monomer polymerization ye-styrene ne-butyl acrylate.
