Hi wihi ntirho wa ti catalysts eka self polymerization reaction ya hydroxyethyl acrylate?
Leswaku self-polymerization reaction yihumelela, mahiselo lawa ya faneleke ya rhanga ya laveka. Hiku angarhela, mahiselo ya kona ya self-polymerization ya hydroxyethyl acrylate KAHLE yi le xikarhi ka 30°C na 60°C. Loko mahiselo yari ehansi swinene, reaction yita nonoka swinene kumbe hambi kuri kunga humeleli. Loko mahiselo yari e henhla swinene, reaction yingava na madzolonga swinene, leswi endlaka leswaku switika ku lawula maendlelo ya reaction naswona swiendla leswaku kuva na switirhisiwa leswinga tshamisekangiki. Hikwalaho, ku lawula mahiselo i swa nkoka swinene! Ku engetela eka mahiselo, ku vonakala na kona i nchumu wa nkoka. Hydroxyethyl acrylate yi angula swinene eka ku vonakala ka ultraviolet (UV), naswona ku vonakala ka UV kunga hlohletela ku hambanisiwa ka ti double bonds ta yona, xisweswo kusunguriwa ku cinca ka polymerization. Ehansi ka UV irradiation, self-polymerization ya hydroxyethyl acrylate hea yita hatlisa swinene. Loko hi tirhisa rivoni ra UV kutani hi ri veka eku vonakaleni ka dyambu, ri ta ti-polymerization hi ku hatlisa. Anakanya ntsena, ehansi ka ku vonakala ka dyambu, timolekhuli leti ti fana ni ku cina, ti hlangana hi ku hatlisa ti vumba swilo leswintshwa. Ku engetela eka mahiselo na ku vonakala, ku hlawuriwa ka catalyst switlhela swi khumba mpimo na mbuyelo wa self-polymerization reaction. Hi ta engetela swin’wana swa swihlohloteri swa peroxide, swo fana na hydrogen peroxide, kumbe swihlanganisi swa azo swo fana na azobisisobutyronitrile (AIBN). Ti catalysts leti tinga hunguta kahle mahiselo yosungula ya self-polymerization reaction, leswi pfumelelaka ku famba kahle hambi kuri eka mahiselo yale hansi. Hakunene ti tirha tanihi swihatlisisi! Handle ka catalyst, reaction yinga nonoka swinene kumbe hambi kuri kunga humeleli. Hikokwalaho, ntirho wa catalyst eka self-polymerization reaction a wu nge honisiwi.
