Fa'atatauga

1. Fa'aoga ile polymerization reactions

4,4'-azobis(4-cyanopentanol) ose fa'amea fa'atosina e mafai ona fa'aogaina e fai ma fa'amataga mo fa'aputuga o polymerization. I le faagasologa o le polymerization radical free, e mafai ona pala e maua ai radical free e amata ai le polymerization monomer. Mo se faʻataʻitaʻiga, i le polymerization tali o vinyl monomers e pei o acrylates ma styrenes, e mafai ona pulea lelei le amataga ma le fua o le polymerization tali. O faʻamaʻi saoloto e maua mai i lona faʻaleagaina e mafai ona amataina le tatalaina o fusi faʻalua i mole mole monomer, ona faʻafesoʻotaʻi lea o le tasi i le isi e fai ai filifili polymer.

O lenei initiator ei ai ni tulaga lelei, e pei o le tuʻuina atu o se fua faʻatupu faʻamalosi fua fua i lalo o tulaga o le vevela talafeagai, ina ia mafai ona faʻagasolo malie le tali polymerization, lea e faʻaogaina i le faʻapipiʻiina o polymers ma se vaapiapi mole mamafa tufatufaina.

2. Matafaioi i le sauniaina o mea fa'afefe

E mafai foi ona faʻaaogaina e saunia ai mea faʻafefe. I le sauniuniga o mea faʻafefe e pei o le polyurethane, 4,4'-azobis(4-cyanopentanol) e mafai ona auai i le tali atu e maua ai le kesi, ma o radical free ma isi vaega faʻamalosi e gaosia e lona decomposition e fesoasoani foi i le faʻaogaina ma le faʻamaloloina o matrices polymer e pei ole polyurethane. O lenei aʻafiaga e lua e mafai ai e le mea faʻafefete ona fausia se fausaga pore toniga, ma le tele ma le tufatufaina o pores e mafai ona pulea e ala i le fetuunaiga o tulaga e pei o latou vailaʻau, faʻaleleia atili ai le tino o le mea faʻafefe, e pei o le faʻaitiitia o le meafaitino, faʻaleleia le elasticity ma mea faʻapipiʻi, ma isi.
