Application
Chigadzirwa chacho chinogona kunyatso tanga polymerization pane yakaderera tembiricha uye yakaderera yekumisikidza kugadzira yakakwira mutsara uye yakakwira molecular uremu polymer.
Va-044 initiator ine yakakwirira yekutanga kushanda zvakanaka, yakakwira molecular huremu, yakanaka solubility yemvura uye zvishoma zvakasara.
VA-044 initiator inowanikwa nekuunza mapoka e-hydrophilic mumorekuru weazonitrile initiators, uye ine mvura yakanaka yekunyungudika.Naizvozvo, VA-044 initiator inowanzokodzera aqueous solution polymerization uye emulsion polymerization yepolymer synthesis.Kuenzaniswa nemhando dzakajairwa dzeazo initiator, VA-044 initiator ine yakakwira yekutangisa kunyatsoita, yakaenzana nehupamhi hwema molecular mass, yakanaka kunyungudika kwemvura, uye muviri wakasara wakaderera.Kuenzaniswa neinorganic persulfate uye mamwe anonyungudika mvura ekutanga, VA-044 initiator inogona kuita yakatsetseka, yakagadzikana uye inodzoreka decomposition reaction kuti ibudise yakakwirira mutsara uye yakakwirira mamorekuru huremu mapolymer.
Kusiyana neazo nitrile zvigadzirwa, nekuti haina cyano mapoka, iyo yekuora zvigadzirwa zveVA-044 initiator haina chepfu.Panguva imwecheteyo, inoora zvishoma nezvishoma kupfuura mamwe ekutanga, ine yakanyanya kutendeuka mwero, uye hapana zvakasara kana agglomeration inoitika panguva yekuita polymerization.Iyo inogona kunyatso tanga polymerization pane yakaderera tembiricha uye yakaderera yekumisikidza kuburitsa yakakwira mutsara uye yakakwira molecular uremu mapolymer.Naizvozvo, VA-044 initiator inoshandiswa zvakanyanya mukugadzirisa aqueous polymerization uye emulsion polymerization yepolymer synthesis, yakadai semonomer acrylamide polymerization, Initiator yepolymerization reactions senge styrene emulsion polymerization uye monomer polymerization ye styrene uye butyl acrylate.
