- Ihe mgbaze: Dị ka achọrọ (na-edozi viscosity).
Njirimara:
- Uru: Nnukwu ọkụ retardant arụmọrụ, obere mgbakwunye ego.
- Ọdịmma: Nwere ike ịmepụta gas na-egbu egbu n'oge ọkụ; nchegbu gburugburu ebe obibi.
3. Ụdị nrapado na-egbochi ọkụ na-enweghị Halogen
Ndị na-ere ọkụ na-enweghị halogen (dịka ọmụmaatụ, dabere na phosphorus, nitrogen ma ọ bụ inorganic hydroxides) na-arụ ọrụ site na mmeghachi omume endothermic ma ọ bụ nhazi oyi akwa, na-enye arụmọrụ gburugburu ebe obibi ka mma.
Ngwa nhazi:
- Ngwunye Isi Ihe: Epoxy resin, polyurethane, ma ọ bụ acrylic.
- Ọkụ dabere na phosphorus: 10-15% (dịka ọmụmaatụ,ammonium polyphosphate APPma ọ bụ red phosphorus).
- Ọkụ na-egbochi Nitrogen: 5–10% (dịka ọmụmaatụ, melamine cyanurate MCA).
- Inorganic hydroxides: 20-30% (dịka, aluminum hydroxide ma ọ bụ magnesium hydroxide).
- Plasticizer: 1-3% (na-eme ka mgbanwe dị mma).
- Onye na-agwọ ọrịa: Ahọpụtara dabere na ụdị nrapado.
- Ihe mgbaze: Dị ka achọrọ (na-edozi viscosity).
Njirimara:
- Uru: Enyi na gburugburu ebe obibi, enweghị ikuku gas na-egbu egbu, na-agbaso ụkpụrụ.
- Ọdịmma: obere ọkụ retardant arụmọrụ, elu mgbakwunye ego, nwere ike imetụta n'ibu Njirimara.
4. Ihe ndị dị mkpa na nhazi nhazi
- Nhọrọ na-egbochi ire ọkụ:
- Halogenated: Ọrụ dị elu mana ọ na-ebute ihe egwu gburugburu ebe obibi na ahụike.
- Halogen-Free: Eco-friendly ma ọ chọrọ nnukwu ọnụọgụ.
- Ndakọrịta: Gbaa mbọ hụ na ọkụ retardant anaghị akpata delamination ma ọ bụ ibelata arụmọrụ njikọ.
- Nhazi: Zenarị nnyonye anya na ọgwụgwọ na flowability.
- Nkwekọrịta gburugburu: Họrọ nhọrọ na-enweghị halogen iji zute RoHS, REACH, wdg.
5. Ngwa a na-ahụkarị
- Ihe owuwu: Ihe mkpuchi ọkụ na-eguzogide ọkụ, ihe nkwụnye ihe nhazi.
- Eletrọnịkị: Circuit osisi encapsulation adhesives, conductive adhesives.
- Ụgbọala: Ihe mkpuchi ọkụ ihu, ihe nkedo ime.
6. Ntụnye nkwalite nhazi nhazi
- Na-eme ka ọ dịgide ọkụ:
- Ngwakọta mmekọrịta (dịka ọmụmaatụ, halogen-antimony, phosphorus-nitrogen).
- Nano ire retardants (dịka ọmụmaatụ, nano magnesium hydroxide ma ọ bụ nano ụrọ) iji melite arụmọrụ ma belata ego mgbakwunye.
- Na-emeziwanye ihe arụrụ arụ:
- Ndị siri ike (dịka, POE ma ọ bụ EPDM) iji kwalite mgbanwe na nguzogide mmetụta.
- Na-eme ka ihe nrụnye dị ike (dịka ọmụmaatụ, eriri iko) iwelie ike na isi ike.
- Mbelata ọnụ ahịa:
- Welie oke nkwụghachi ọkụ ka ibelata ojiji mgbe ị na-emezu ihe achọrọ.
- Họrọ ihe ndị dị ọnụ ala (dịka ọmụmaatụ, ihe ọkụ ọkụ ụlọ ma ọ bụ agwakọtara agwakọta).
7. Ihe ndị chọrọ gburugburu ebe obibi na usoro iwu
- Halogenated Flame Retardants: Amachibidoro n'okpuru RoHS, REACH, wdg; jiri nlezianya mee ihe.
- Halogen na-akwụsị ire ọkụ: Dabere na ụkpụrụ; omume n'ọdịnihu.
8. Nchịkọta
Ekwesịrị ịhazi usoro nkwụchi ọkụ nrapado dabere na ngwa ndị akọwapụtara na iwu chọrọ, ịhọrọ n'etiti nhọrọ halogenated ma ọ bụ enweghị halogen. Ndị na-ere ọkụ halogenated na-enye arụmọrụ dị elu mana na-ebute ihe egwu gburugburu ebe obibi, ebe ndị ọzọ na-enweghị halogen bụ enyi na enyi mana ọ chọrọ nnukwu mgbakwunye. Site n'ịkwalite usoro na usoro, arụ ọrụ dị elu, enyi na gburugburu ebe obibi, na ọnụ ahịa ọkụ na-egbochi ọkụ nwere ike ịmepụta maka ihe owuwu, ngwá electronic, ụgbọala, na ụlọ ọrụ ndị ọzọ.
