Daim Ntawv Thov

1. Daim ntawv thov hauv cov tshuaj tiv thaiv polymerization

4,4'-azobis (4-cyanopentanol) yog ib qho azo compound uas siv tau ua tus pib rau cov tshuaj polymerization. Hauv cov txheej txheem ntawm cov dawb radical polymerization, nws tuaj yeem decompose los tsim cov dawb radicals los pib monomer polymerization. Piv txwv li, hauv cov tshuaj polymerization ntawm vinyl monomers xws li acrylates thiab styrenes, nws tuaj yeem tswj tau qhov pib thiab tus nqi ntawm cov tshuaj polymerization. Cov dawb radicals tsim los ntawm nws qhov decomposition tuaj yeem pib qhib cov ob chav bonds hauv cov monomer molecules, thiab tom qab ntawd txuas rau ib leeg los tsim cov polymer saw.

Tus pib no muaj qee qhov zoo, xws li muab cov nqi tsim tawm dawb radical ruaj khov nyob rau hauv qhov kub thiab txias, yog li ntawd qhov kev sib xyaw ua ke polymerization tuaj yeem ua mus zoo, uas yog qhov zoo rau kev tsim cov polymers nrog qhov faib tawm molecular nqaim.

2. Lub luag haujlwm hauv kev npaj cov ntaub ntawv ua npuas ncauj

Nws kuj tseem siv tau los npaj cov khoom ua npuas ncauj. Hauv kev npaj cov khoom ua npuas ncauj xws li polyurethane, 4,4'-azobis (4-cyanopentanol) tuaj yeem koom nrog hauv kev tshuaj tiv thaiv los tsim cov roj, thiab cov dawb radicals thiab lwm cov pab pawg nquag tsim los ntawm nws qhov kev lwj kuj pab txhawb rau kev sib txuas thiab kho ntawm cov polymer matrices xws li polyurethane. Qhov txiaj ntsig ob npaug no ua rau cov khoom ua npuas ncauj tsim cov qauv pore sib xws, thiab qhov loj me thiab kev faib tawm ntawm cov pores tuaj yeem tswj tau los ntawm kev kho cov xwm txheej xws li lawv cov koob tshuaj, yog li txhim kho cov khoom siv lub cev ntawm cov khoom ua npuas ncauj, xws li txo cov khoom siv ceev, txhim kho cov khoom siv elasticity thiab cov khoom cushioning, thiab lwm yam.
