Sebopeho sa litšupiso tse se nang Halogen tse thibelang malakabe bakeng sa likhomaretsi tsa elektroniki tsa acrylic tse thehiloeng metsing
Lits'ebetsong tsa acrylic tse thehiloeng metsing, palo ea tlatsetso ea aluminium hypophosphite (AHP) le zinki borate (ZB) e lokela ho khethoa ho latela litlhoko tse ikhethileng tsa ts'ebeliso (joalo ka tekanyo ea ho lieha ha lelakabe, botenya ba ho roala, litlhoko tsa ts'ebetso ea 'mele, joalo-joalo) le litlamorao tsa bona tsa synergistic. Ka tlase ke likhothaletso tse akaretsang le mefuta ea litšupiso:
I. Baseline Addition Amounts Reference
Lethathamo: Kenyelletso le Litlhaloso tsa Flame Retardant tse khothalelitsoeng
| Mofuta oa Lelakabe le Retardant | Kenyelletso e khothalelitsoeng (wt%) | Tlhaloso |
| Aluminium Hypophosphite (AHP) | 5%~20% | Phosphorus-based retardant flame; leka-lekanya katleho ea ho khutlisa lelakabe le ts'ebelisano ea sistimi (litekanyo tse feteletseng li ka ama thepa ea mochini). |
| Zinc Borate (ZB) | 2%~10% | Synergistic enhancer; e ka fokotsa kakaretso ea tlatsetso ha e kopantsoe le AHP (karolo e phahameng e hlokahalang ha e sebelisoa e le mong). |
II. Ntlafatso ea Likhakanyo tsa Motsoako
- Mefuta e Tloaelehileng ea Motsoako:
- AHP:ZB = 2:1 ~ 4:1(mohlala, 15% AHP + 5% ZB, kakaretso ea 20%).
- Fetola likarohano ka liteko, mohlala:
- Tlhokahalo e phahameng ea ho lieha lelakabe:AHP 15%~20%, ZB 5%~8%.
- E leka-lekaneng thepa ea 'mele:AHP 10%~15%, ZB 3%~5%.
- Liphello tsa Synergistic:
- Zinc borate e ntlafatsa ho lieha ha lelakabe ka:
- Ho tsitsisa sebopeho sa char (ho sebelisana le aluminium phosphate e hlahisoang ke AHP).
- Ho lokolla metsi a tlanngoeng ho monya mocheso le ho hlapolla likhase tse tukang.
III. Mehato ea Teko ea ho netefatsa
- Teko ea Stepwise:
- Teko ea motho ka mong:Ntlha ea pele, hlahloba AHP (5% ~ 20%) kapa ZB (5% ~ 15%) ka thoko bakeng sa ho lieha ha lelakabe (UL-94, LOI) le ts'ebetso ea ho roala (ho khomarela, ho thatafala, ho hanyetsa metsi).
- Ntlafatso ea komporo:Ka mor'a ho khetha palo ea motheo ea AHP, eketsa ZB ka ho eketseha (mohlala, 3% ho isa ho 8% ha AHP e le 15%) 'me u hlokomele ntlafatso ea ho lieha ha lelakabe le litla-morao.
- Lipontšo tsa Ts'ebetso ea Bohlokoa:
- Ho lieha ha lelakabe:LOI (sepheo sa ≥28%), tekanyo ea UL-94 (V-0/V-1), sekhahla sa mosi.
- Lintho tsa 'mele:Ho thehoa ha filimi, ho khomarela (ASTM D3359), ho hanyetsa metsi (ha ho na delamination ka mor'a ho qoelisoa ka 48h).
IV. Lintlha Tse ka Sehloohong
- Botsitso ba Phatlalatso:
- AHP ke hygroscopic — e omme pele kapa e sebelisa mefuta e fetotsoeng kaholimo.
- Sebelisa li-disperants (mohlala, BYK-190, TEGO Dispers 750W) ho ntlafatsa ho tšoana le ho thibela sedimentation.
- Ho lumellana ha pH:
- Lisebelisoa tsa acrylic tse thehiloeng metsing hangata li na le pH ea 8-9; etsa bonnete ba hore AHP le ZB li lula li tsitsitse (qoba hydrolysis kapa ho bola).
- Tumellano ea Taolo:
- AHP e tlameha ho fihlela litlhoko tsa RoHS tse se nang halogen; ZB e lokela ho sebelisa limaraka tse tlase tsa boima ba tšepe.
V. Mekhoa e meng kapa ea Tlatsetso
- Melamine Polyphosphate (MPP):E ka ntlafatsa ho lieha ha lelakabe ho feta ha e kopantsoe le AHP (mohlala, 10% AHP + 5% MPP + 3% ZB).
- Nano Flame Retardants:Nano-grade ZB (keketso e fokotsehile ho 1% ~ 3%) kapa layered double hydroxides (LDH) bakeng sa liphello tse ntlafetseng tsa thibelo.
VI. Kakaretso ea Likhothaletso
- Mokhoa oa ho qala:AHP 10% ~ 15% + ZB 3% ~ 5% (kakaretso 13% ~ 20%), ebe u ntlafatsa.
- Mokhoa oa ho netefatsa:Lekola lisampole tse nyane tsa LOI le UL-94 ha u ntse u hlahloba thepa ea mochini.
