Daim ntawv thov

1. Daim ntawv thov hauv cov tshuaj tiv thaiv polymerization

4,4'-azobis (4-cyanopentanol) yog ib qho azo compound uas tuaj yeem siv los ua tus thawj coj rau cov tshuaj tiv thaiv polymerization. Nyob rau hauv tus txheej txheem ntawm dawb radical polymerization, nws tuaj yeem decompose los tsim cov dawb radicals los pib monomer polymerization. Piv txwv li, nyob rau hauv cov tshuaj tiv thaiv polymerization ntawm vinyl monomers xws li acrylates thiab styrenes, nws muaj peev xwm tswj tau qhov pib thiab tus nqi ntawm cov tshuaj tiv thaiv polymerization. Cov dawb radicals tsim los ntawm nws cov decomposition tuaj yeem pib qhib ob daim ntawv cog lus hauv monomer molecules, thiab tom qab ntawd txuas mus rau ib leeg los tsim cov saw hlau polymer.

Tus thawj tswj hwm no muaj qee qhov zoo, xws li muab cov qauv dawb radicals ruaj khov nyob rau hauv qhov tsim nyog kub, kom cov tshuaj tiv thaiv polymerization tuaj yeem ua tau zoo, uas yog qhov zoo rau kev sib xyaw ntawm cov polymers nrog qhov nqaim molecular yuag.

2. Lub luag haujlwm ntawm kev npaj cov ntaub ntawv foaming

Nws kuj tseem siv tau los npaj cov ntaub ntawv foaming. Hauv kev npaj cov ntaub ntawv foaming xws li polyurethane, 4,4'-azobis (4-cyanopentanol) tuaj yeem koom nrog cov tshuaj tiv thaiv los tsim cov roj, thiab cov dawb radicals thiab lwm pab pawg ua haujlwm uas tsim los ntawm nws cov decomposition kuj ua rau kev sib txuas thiab kho cov polymer matrices xws li polyurethane. Cov nyhuv ob no ua rau cov khoom siv foaming los tsim cov qauv pore, thiab qhov loj thiab kev faib tawm ntawm qhov pores tuaj yeem tswj tau los ntawm kev kho cov xwm txheej xws li lawv cov tshuaj, yog li txhim kho lub cev ntawm cov khoom foaming, xws li txo cov khoom ntom ntom, txhim kho cov khoom elasticity thiab cushioning zog, thiab lwm yam.
