Uru na Ọdịmma nke Inorganic Flame Retardants

Iji ihe polymer eme ihe n'ọtụtụ ebe emeela ka uto nke ụlọ ọrụ na-ere ọkụ ọkụ. Ndị na-ere ọkụ bụ akụkụ dị oke mkpa nke mgbakwunye ihe onwunwe n'ime ọha mmadụ taa, na-egbochi ọkụ nke ọma, na-achịkwa mgbasa ha, na-atụnye ụtụ nke ukwuu na nchekwa mmepụta na ndụ kwa ụbọchị. Akụrụngwa ejiri ihe ndị na-egbochi ire ọkụ na-agwọ nwere ike igbochi, nwayọ, ma ọ bụ kwụsị mgbasa nke ire ọkụ mgbe a na-ekpughere ya na isi ọkụ dịpụrụ adịpụ, si otú ahụ nweta mmetụta na-egbochi ire ọkụ. Enwere ọtụtụ ụdị ọkụ retardants, na ihe niile nwere akụkụ abụọ-ọkụ retardants nwekwara uru na ọghọm ha. N'okpuru ebe a bụ nyocha nke uru na ọghọm dị iche iche nke inorganic ire ọkụ retardants.

Ọdịmma nke Inorganic Flame Retardants:
Isi ihe ndọghachi azụ nke ndị na-ere ọkụ inorganic bụ usoro ha chọrọ dị elu (karịa karịa 50%) na ihe polymer, nke nwere ike imebi arụmọrụ nhazi yana akụrụngwa anụ ahụ ngwa ngwa. Ngwọta gụnyere ọgwụgwọ elu ya na ndị na-ejikọta ọnụ, mmụgharị ultrafine, na nanotechnology, nke na-anọchite anya isi ntụzịaka maka mmepe n'ọdịnihu.

Uru nke Inorganic Flame Retardants:

1. Aluminium Hydroxide (ATH): Na-ejikọta ire ọkụ, nkwụsị ọkụ, na njuputa ọrụ n'ime otu. Ọ naghị egbu egbu, anaghị emebi emebi, kwụsie ike nke ukwuu, anaghị emepụta gas na-egbu egbu na oke okpomọkụ, ọ na-efu ọnụ, yana ebe niile.
2. Magnesium Hydroxide (MTH): Na-emebi n'etiti 340-490ºC, na-enye ezigbo nkwụsi ike nke okpomọkụ yana nkwụghachi ọkụ pụtara ìhè na mmetụta nkwụsị anwụrụ ọkụ. Ọ kachasị mma maka nhazi polyolefin plastik na okpomọkụ dị elu.
3. Uhie Phosphorus: Na-enye nkwụsị anwụrụ ọkụ, obere nsi, na ogologo oge ire ọkụ. Otú ọ dị, phosphorus na-acha uhie uhie na-adị mfe ịnweta ikuku oxidation, nwere ike ịgba ọkụ na mberede, ma jiri nwayọọ nwayọọ na-ahapụ gas phosphine na-egbu egbu maka nchekwa ogologo oge. Ndakọrịta ya na ihe ndị polymer adịghị mma, na microencapsulation bụ isi ihe ngwọta.
4. Ammonium Polyphosphate (APP): Ọ bụkwa ihe na-egbochi ire ọkụ, ọ nwere nnukwu nitrogen na phosphorus, na-egosipụta nkwụsi ike nke okpomọkụ dị mma, ọ fọrọ nke nta ka ọ ghara ịnọpụ iche na nhazi. Enwere ike ịgwakọta ya na ihe ndị ọzọ na-ere ọkụ, na-enye mgbasa ozi dị mma, ma dị ntakịrị na nsị, na-eme ka ojiji dị mma. Agbanyeghị, mgbe ogo polymerization nke APP na-ebelata, ọ na-aghọ ntakịrị mmiri soluble. Na mgbakwunye, APP dị ntakịrị acidic na ọ na-adịkarị mfe ịnweta mmiri na gburugburu iru mmiri.
