1. Tšebeliso liketsong tsa polymerization

4,4'-azobis (4-cyanopentanol) ke motsoako oa azo o ka sebelisoang e le moqali oa liketso tsa polymerization. Ts'ebetsong ea polymerization ea free radical, e ka bola ho hlahisa li-free radical ho qala polymerization ea monomer. Mohlala, karabelong ea polymerization ea li-monomer tsa vinyl tse kang li-acrylates le li-styrenes, e ka laola ka katleho qalo le sekhahla sa karabelo ea polymerization. Li-free radical tse hlahisoang ke ho bola ha eona li ka qala ho buloa ha litlamo tse habeli limolek'huleng tsa monomer, ebe lia hokahana ho theha liketane tsa polymer.

Moqali enoa o na le melemo e itseng, joalo ka ho fana ka sekhahla se tsitsitseng sa tlhahiso ea li-free radical tlas'a maemo a loketseng a mocheso, e le hore karabelo ea polymerization e ka tsoela pele hantle, e leng se thusang ho kopanngoa ha li-polymer tse nang le kabo e tšesaane ea boima ba limolek'hule.

2. Karolo ea ho lokisa thepa ea foam

E ka boela ea sebelisoa ho lokisa thepa ea foam. Ha ho lokisoa thepa ea foam joalo ka polyurethane, 4,4'-azobis (4-cyanopentanol) e ka nka karolo karabelong ea ho hlahisa khase, 'me li-free radical le lihlopha tse ling tse sebetsang tse hlahisoang ke ho bola ha eona le tsona li kenya letsoho ho hokahaneng le ho phekoleng ha matrices ea polymer joalo ka polyurethane. Phello ena e habeli e nolofalletsa thepa ea foam ho theha sebopeho se tšoanang sa pore, 'me boholo le kabo ea li-pore li ka laoloa ka ho fetola maemo a kang tekanyo ea tsona, ka hona ho ntlafatsa thepa ea 'mele ea thepa ea foam, joalo ka ho fokotsa bongata ba thepa, ho ntlafatsa ho tenyetseha ha thepa le thepa ea cushion, jj.
