Ifomyula yesalathiso esithintela ilangatye engenalo i-halogen kwizincamathelisi ze-elektroniki ze-acrylic ezisekelwe emanzini

Kwiinkqubo ze-acrylic ezisekelwe emanzini, ubungakanani bokongeza i-aluminium hypophosphite (AHP) kunye ne-zinc borate (ZB) kufuneka bumiselwe ngokusekelwe kwiimfuno ezithile zokusetyenziswa (ezifana nokulinganiswa kokulinda ilangabi, ubukhulu bengubo, iimfuno zokusebenza ngokomzimba, njl.njl.) kunye nemiphumo yazo yokusebenzisana. Ngezantsi kukho iingcebiso ngokubanzi kunye noluhlu lwesalathiso:

I. Isalathiso seeMali ezongeziweyo zesiseko

Itheyibhile: Izongezo ezicetyiswayo kunye neenkcazo ezithintela ilangatye

II. Ukuphuculwa kweeRatios eziQokelelweyo

1. IiRatio eziQhelekileyo zeCompound:

• AHP:ZB = 2:1 ~ 4:1(umz., i-15% AHP + 5% ZB, iyonke i-20%).
• Lungisa ii-ratios ngovavanyo, umzekelo:
• Imfuno ephezulu yokuthintela ilangatye:I-AHP 15%~20%, i-ZB 5%~8%.
• Iimpawu zomzimba ezilinganayo:I-AHP 10%~15%, i-ZB 3%~5%.

1. Iziphumo zokusebenzisana:

• I-Zinc borate iphucula ukungakwazi komlilo ngokuthi:
• Ukuzinzisa ukwakheka kwe-char (ukusebenzisana ne-aluminium phosphate eyenziwe yi-AHP).
• Ukukhulula amanzi adibeneyo ukuze kufunxwe ubushushu kwaye kuncitshiswe iigesi ezivuthayo.

III. Amanyathelo okuqinisekisa uvavanyo

1. Uvavanyo oluhamba ngenyathelo:

• Uvavanyo lomntu ngamnye:Okokuqala jonga i-AHP (5%~20%) okanye i-ZB (5%~15%) ngokwahlukeneyo ukuze ubone ukuba i-flame retardancy (UL-94, LOI) isebenza njani kwaye ifake i-coating (ukunamathela, ubulukhuni, ukumelana namanzi).
• Ukulungiswa kwe-compound:Emva kokukhetha isixa se-AHP esisisiseko, yongeza i-ZB kancinci kancinci (umz., i-3% ukuya kwi-8% xa i-AHP iyi-15%) kwaye ujonge ukuphucuka kokungavuthi komlilo kunye nemiphumo emibi.

1. Izalathisi Zokusebenza Eziphambili:

• Ukungavumi komlilo:I-LOI (ekujoliswe kuyo ≥28%), umlinganiselo we-UL-94 (V-0/V-1), ukuxinana komsi.
• Iimpawu ezibonakalayo:Ukwakheka kwefilimu, ukunamathela (ASTM D3359), ukumelana namanzi (akukho kususwa kwefilimu emva kokuntywiliselwa kwiiyure ezingama-48).

IV. Izinto ezibalulekileyo ekufuneka ziqwalaselwe

• Uzinzo lokusasazeka:
• I-AHP i-hygroscopic—yomiswa ngaphambi kokuba yomiswe okanye isebenzise iintlobo eziguqulweyo kumphezulu.
• Sebenzisa izisasazi (umz., i-BYK-190, i-TEGO Dispers 750W) ukuphucula ukufana kunye nokuthintela ukubola.
• Ukuhambelana kwe-pH:
• Iinkqubo ze-acrylic ezisekelwe emanzini zihlala zine-pH ye-8–9; qinisekisa ukuba i-AHP kunye ne-ZB zihlala zizinzile (kuphephe i-hydrolysis okanye ukubola).
• Ukuthobela iMithetho:
• I-AHP kufuneka ihlangabezane neemfuno ze-RoHS ezingenayo i-halogen; i-ZB kufuneka isebenzise amanqanaba aphantsi okungcola kwesinyithi esinzima.

V. Izisombululo ezizezinye okanye ezongezelelweyo

• I-Melamine Polyphosphate (MPP):Ingaphucula ngakumbi ukulibaziseka kwelangatye xa idityaniswe ne-AHP (umz., i-10% AHP + 5% MPP + 3% ZB).
• Izinto ezithintela ilangatye leNano:I-Nano-grade ZB (ukongeza kuncitshiswe ukuya kwi-1%~3%) okanye ii-layered double hydroxides (LDH) ukuze kuphuculwe iziphumo zokuthintela.

VI. Isishwankathelo seengcebiso

• Ukuqala kwefomyula:I-AHP 10%~15% + ZB 3%~5% (iyonke yi-13%~20%), uze uyilungise.
• Indlela yokuqinisekisa:Vavanya iisampulu ezincinci ze-LOI kunye ne-UL-94 ngelixa uvavanya iimpawu zoomatshini.
