Nkà na ụzụ na-egbochi ọkụ nke roba

Ewezuga ngwaahịa rọba sịntetị ole na ole, ọtụtụ ngwaahịa rọba sịntetịt, dị ka rọba eke, bụ ihe na-ere ọkụ ma ọ bụ ọkụ. Ka ọ dị ugbu a, ụzọ ndị bụ isi a na-esi eme ka ọkụ na-akwụsị ire bụ ịgbakwụnye ihe ndị na-ere ọkụ ma ọ bụ ihe na-eme ka ọkụ na-agbakọta ma gbanwee ya na ihe na-egbochi ọkụ. Enwere ọtụtụ ụdị teknụzụ na-egbochi ọkụ maka roba:
1. Hydrocarbon roba
Hydrocarbon roba gụnyere NR, SBR, BR, wdg Hydrocarbon roba n'ozuzu nwere ogbenye okpomọkụ na-eguzogide na ire ere retardancy, na ọtụtụ n'ime decomposition ngwaahịa n'oge combustion bụ combustible gas. Ịgbakwunye ọkụ retardants bụ ụzọ dị mkpa iji meziwanye ọkụ retardancy nke hydrocarbon roba, na synergistic mmetụta nke ire retardants na-eji na-eme ka ire ere retardans mmetụta. Otú ọ dị, ekwesịrị ịṅa ntị na mmetụta ọjọọ nke ọnụọgụ ọkụ ọkụ na-arụ ọrụ na-arụ ọrụ nke roba.
Tinye ọkụ na-egbochi inorganic fillers dị ka calcium carbonate, ụrọ, talcum ntụ ntụ, na-acha ọcha carbon ojii, Aluminum hydroxide, wdg ka ibelata oke nke organic ihe combustible. Calcium carbonate na nitrogen alumina nwere mmetụta endothermic mgbe ire ere. Usoro a ga-ebelata ụfọdụ ihe anụ ahụ na arụ ọrụ nke ihe eji eme rọba, na njuputa na-ejuputa ekwesịghị ịdị ukwuu.
Na mgbakwunye, ịba ụba njupụta nke rọba nwere ike ime ka ndeksi oxygen dịkwuo elu. Ya mere, ọ nwere ike melite ọkụ retardancy nke roba. Nke a nwere ike ịbụ n'ihi mmụba nke okpomọkụ ire ere nke ihe rubber. A na-etinye usoro a na roba Ethylene propylene
2. roba halogenated
Roba halogenated nwere ihe halogen, nke nwere ihe nrịbama oxygen n'ozuzu n'etiti 28 na 45, na nrịbama oxygen nke FPM ọbụna karịa 65. Ka ọdịnaya halogen dị na roba halogenated dị elu, ka ọnụọgụ oxygen ya dị elu. Ụdị rọba a n'onwe ya nwere nnukwu ire ere na-ekpochapụ onwe ya mgbe ọ gbanyere ọkụ. Ya mere, ọgwụgwọ retardant ire ọkụ dị mfe karịa hydrocarbon roba. Iji meziwanye ọkụ ọkụ nke rubber halogenated, a na-anabatakarị usoro ịgbakwụnye ọkụ ọkụ.
3. Heterochain roba
The kasị nnọchiteanya ụdị roba na nke a Atiya bụ dimethyl silicone roba, na ihe oxygen index nke gburugburu 25. The n'ezie ire retardant ụzọ eji na-amụba ya thermal decomposition okpomọkụ, dịkwuo ihe fọdụrụ n'oge thermal decomposition, na-ebelata mmepụta ọnụego nke. ọkụ ọkụ.
