Ntụaka nrụtụ aka maka ire ọkụ na-enweghị halogen maka nrapado eletrọkị acrylic dabere na mmiri

Na usoro acrylic nke dabeere na mmiri, a ga-ekpebi ihe mgbakwunye nke aluminom hypophosphite (AHP) na zinc borate (ZB) dabere na ihe achọrọ ngwa ngwa (dị ka ọkwa retardancy ọkụ, ọkpụrụkpụ mkpuchi, chọrọ ịrụ ọrụ anụ ahụ, wdg) na mmetụta synergistic ha. N'okpuru bụ ntụnye izugbe na oke ntụaka:

I. Ntụtụ aka ngụkọ nke Baseline

Tebụl: Mgbakwunye na nkọwapụta ire ọkụ akwadoro

II. Nkwalite oke nke ngwakọta

1. Oke Ngwakọta ahụkarị:

• AHP:ZB = 2:1 ~ 4:1(dịka ọmụmaatụ, 15% AHP + 5% ZB, ngụkọta 20%).
• Gbanwee nha site na nnwale, dịka ọmụmaatụ:
• Achọrọ ogologo ntachi obi ọkụ:AHP 15% ~ 20%, ZB 5% ~ 8%.
• Njirimara anụ ahụ dabara adaba:AHP 10% ~ 15%, ZB 3% ~ 5%

1. Mmetụta mmekọrịta

• Zinc borate na-akwalite ire ere site na:
• Nhazi cha cha na-emekọrịta ihe na aluminom phosphate nke AHP mepụtara.
• Na-ahapụ mmiri a kechie ka ọ na-amịkọrọ okpomọkụ ma mee ka ikuku na-ere ọkụ.

III. Nzọụkwụ nkwado nnwale

1. Nnwale usoro nzọụkwụ:

• Nnwale nke onwe:Buru ụzọ nyochaa AHP (5% ~ 20%) ma ọ bụ ZB (5% ~ 15%) iche maka ire ọkụ ọkụ (UL-94, LOI) na mkpuchi mkpuchi (adhesion, hardness, water resistance).
• Nkwalite ngwakọta:Mgbe ịhọrọchara ego AHP ntọala, tinyekwuo ZB (dịka ọmụmaatụ, 3% ruo 8% mgbe AHP bụ 15%) wee hụ mmelite na nkwụghachi ọkụ na mmetụta ndị ọzọ.

1. Ihe ngosi arụmọrụ igodo:

• Ọnwụ anwụ:LOI (ezubere ≥28%), ọkwa UL-94 (V-0/V-1), njupụta anwụrụ ọkụ.
• Njirimara anụ ahụ:Nhazi ihe nkiri, adhesion (ASTM D3359), mgbochi mmiri (enweghị delamination mgbe imikpu 48h gasịrị).

IV. Isi Ntụle

• Nkwụsi ike mgbasa:
• AHP bụ hygroscopic - akpọọla ya ma ọ bụ jiri ụdị dị iche iche emezigharịrị.
• Jiri ndị na-ekesa (dịka, BYK-190, TEGO Dispers 750W) iji kwalite ịdị n'otu ma gbochie sedimentation.
• ndakọrịta pH:
• Usoro acrylic nke dabeere na mmiri na-enwekarị pH nke 8-9; hụ na AHP na ZB kwụsiri ike (zere hydrolysis ma ọ bụ ire ere).
• Nrube isi n'usoro iwu:
• AHP ga-emezurịrị ihe RoHS na-enweghị halogen; ZB kwesịrị iji akara adịghị ọcha dị ala dị arọ.

V. Nhọrọ ọzọ ma ọ bụ mgbakwunye

• Melamine Polyphosphate (MPP):Nwere ike ịkwalite nkwụghachi ọkụ mgbe ejikọtara ya na AHP (dịka, 10% AHP + 5% MPP + 3% ZB).
• Nano Flame Retardants:Nano-grade ZB (mgbakwunye belata na 1% ~ 3%) ma ọ bụ Layered double hydroxides (LDH) maka mmetụta mgbochi ka mma.

VI. Nchịkọta Aro

• Nhazi mmalite:AHP 10% ~ 15% + ZB 3% ~ 5% (mkpokọta 13% ~ 20%), wee bulie ya.
• Usoro nkwado:Nwalee nlele obere maka LOI na UL-94 ka ị na-enyocha akụrụngwa igwe.
