Kopo

1. Kopo ka karabelo ea polymerization

4,4'-azobis(4-cyanopentanol) ke motsoako oa azo o ka sebelisoang e le mothehi oa karabelo ea polymerization. Ts'ebetsong ea polymerization ea mahala, e ka bola ho hlahisa li-radicals tsa mahala ho qala polymerization ea monomer. Ka mohlala, ka karabelo ea polymerization ea vinyl monomers tse kang acrylates le styrenes, e ka khona ho laola ka katleho ho qaleha le sekhahla sa karabelo ea polymerization. Li-radicals tsa mahala tse hlahisoang ke ho senyeha ha tsona li ka qala ho buloa ha litlamo tse peli ho limolek'hule tsa monomer, ebe li hokahana ho etsa liketane tsa polymer.

Moqapi ona o na le melemo e itseng, e kang ho fana ka tekanyo e batlang e tsitsitse ea ho hlahisa radical mahala tlas'a maemo a loketseng a mocheso, e le hore karabelo ea polymerization e ka tsoela pele hantle, e leng se loketseng ho kopanngoa ha li-polymers tse nang le boima bo fokolang ba limolek'hule.

2. Karolo ea ho lokisa thepa e phophomang

E ka boela ea sebelisoa ho lokisetsa lisebelisoa tse foaming. Ha ho lokisoa lisebelisoa tse kang polyurethane, 4,4'-azobis(4-cyanopentanol) e ka kenya letsoho karabelong ea ho hlahisa khase, 'me li-radicals tsa mahala le lihlopha tse ling tse sebetsang tse hlahisoang ke ho bola ha tsona le tsona li kenya letsoho ho hokahaneng le ho folisa matrices a polymer joalo ka polyurethane. Phello ena e habeli e etsa hore thepa e phophomang e thehe sebopeho sa pore se ts'oanang, 'me boholo le kabo ea li-pores li ka laoloa ka ho lokisa maemo a joalo ka litekanyetso tsa bona, ka hona ho ntlafatsa thepa ea' mele ea thepa e phophomang, joalo ka ho fokotsa bongata ba thepa, ho ntlafatsa boleng ba thepa le thepa ea cushioning, jj.
