Lub luag haujlwm ntawm cov catalysts hauv qhov kev sib xyaw ua ke ntawm hydroxyethyl acrylate yog dab tsi?
Rau qhov kev ua kom tus kheej-polymerization tshwm sim, qhov kub thiab txias tsim nyog yog qhov yuav tsum tau ua ntej. Feem ntau, qhov kub thiab txias rau tus kheej-polymerization ntawm hydroxyethyl acrylate ZOO yog nruab nrab ntawm 30 ° C thiab 60 ° C. Yog tias qhov kub qis dhau, qhov kev tshuaj tiv thaiv yuav qeeb heev lossis tsis tshwm sim. Yog tias qhov kub siab dhau, qhov kev tshuaj tiv thaiv yuav dhau los ua kev kub ntxhov, ua rau nws nyuaj rau tswj cov txheej txheem tshuaj tiv thaiv thiab ua rau cov khoom tsis ruaj khov. Yog li ntawd, kev tswj qhov kub thiab txias yog qhov tseem ceeb heev! Ntxiv nrog rau qhov kub thiab txias, lub teeb kuj yog ib qho tseem ceeb. Hydroxyethyl acrylate muaj kev cuam tshuam ntau rau lub teeb ultraviolet (UV), thiab lub teeb UV tuaj yeem txhawb kev sib cais ntawm nws cov ntawv cog lus ob npaug, yog li pib qhov kev tshuaj tiv thaiv polymerization. Hauv qab UV irradiation, qhov kev ua kom tus kheej ntawm hydroxyethyl acrylate hea yuav sai dua. Yog tias peb siv lub teeb UV lossis tso rau hauv tshav ntuj, nws yuav dhau los ua tus kheej-polymerization sai. Xav txog, hauv qab tshav ntuj, cov molecules no zoo li seev cev, sib xyaw ua ke sai sai los tsim cov tshuaj tshiab. Ntxiv nrog rau qhov kub thiab txias, kev xaiv ntawm catalyst kuj cuam tshuam rau tus nqi thiab cov nyhuv ntawm qhov kev ua kom tus kheej-polymerization. Peb yuav ntxiv qee cov catalysts peroxide, xws li hydrogen peroxide, lossis azo compounds zoo li azobisisobutyronitrile (AIBN). Cov catalysts no tuaj yeem txo qhov kub pib ntawm cov tshuaj tiv thaiv tus kheej-polymerization, ua rau nws mus tau zoo txawm tias nyob rau hauv qhov kub qis dua. Lawv yeej ua haujlwm ua cov accelerators! Yog tsis muaj catalyst, qhov tshuaj tiv thaiv yuav qeeb heev lossis txawm tias tsis tshwm sim. Yog li ntawd, lub luag haujlwm ntawm catalyst hauv cov tshuaj tiv thaiv tus kheej-polymerization tsis tuaj yeem tsis quav ntsej.
