Sebopeho sa litšupiso tse thibelang malakabe tse se nang halogen bakeng sa likhomaretsi tsa elektroniki tsa acrylic tse thehiloeng metsing
Litsamaisong tsa acrylic tse thehiloeng metsing, bongata ba ho eketsa aluminium hypophosphite (AHP) le zinc borate (ZB) bo lokela ho khethoa ho latela litlhoko tse itseng tsa ts'ebeliso (joalo ka tekanyo ea ho lieha ha mollo, botenya ba ho roala, litlhoko tsa ts'ebetso ea 'mele, jj.) le litlamorao tsa tsona tsa tšebelisano-'moho. Ka tlase ke likhothaletso tse akaretsang le mefuta ea litšupiso:
I. Litšupiso tsa Chelete e Eketsoang ea Motheo
Tafole: Litlhaloso le Litlhaloso tse Khothaletsoang tsa ho Thibela Mollo
| Mofuta oa ho Sireletsa Mollo | Ho eketsa ho kgothaletswang (boima ba %) | Tlhaloso |
| Aluminium Hypophosphite (AHP) | 5%~20% | Sethibela-mollo se thehiloeng ho phosphorus; leka-lekanya bokgoni ba ho thibela mollo le ho tsamaisana ha sistimi (bongata bo feteletseng bo ka ama thepa ea mechini). |
| Borate ea Zinki (ZB) | 2%~10% | Sesebelisoa sa ho eketsa matla a kopaneng; se ka fokotsa tlatsetso e felletseng ha se kopantsoe le AHP (boholo bo hlokahalang haeba se sebelisoa se le seng). |
II. Ntlafatso ea Likarolelano tse Kopantsoeng
- Litekanyetso tse Tloaelehileng tsa Motsoako:
- AHP:ZB = 2:1 ~ 4:1(mohlala, 15% AHP + 5% ZB, kakaretso ea 20%).
- Fetola dikarolelano ka teko, mohlala:
- Tlhokeho e phahameng ea ho lieha ha lelakabe:AHP 15%~20%, ZB 5%~8%.
- Thepa ea 'mele e leka-lekaneng:AHP 10%~15%, ZB 3%~5%.
- Litlamorao tsa ho sebelisana 'moho:
- Zinc borate e eketsa ho tima ha lelakabe ka:
- Ho tsitsisa sebopeho sa char (ho sebelisana le aluminium phosphate e hlahisoang ke AHP).
- Ho lokolla metsi a tlamiloeng ho monya mocheso le ho fokotsa likhase tse tukang.
III. Mehato ea Netefatso ea Liteko
- Teko ea Mohato ka Mohato:
- Teko ea motho ka mong: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 motsoako:Kamora ho kgetha palo ya motheo ya AHP, eketsa ZB hanyane ka hanyane (mohlala, 3% ho isa ho 8% ha AHP e le 15%) mme o bone dintlafatso tsa ho tiea ha lelakabe le ditlamorao tse mpe.
- Matšoao a Bohlokoa a Tshebetso:
- Ho lieha ha lelakabe:LOI (sepheo ≥28%), tekanyo ea UL-94 (V-0/V-1), ho ba le mosi o teteaneng.
- Thepa ea 'mele:Ho thehoa ha filimi, ho khomarela (ASTM D3359), ho hanyetsa metsi (ha ho na ho arohana ha letlalo ka mor'a ho qoelisoa lihora tse 48).
IV. Lintlha tsa bohlokoa tsa ho nahana
- Ho Tsitsisa ha ho Hasana:
- AHP e na le hygroscopic—e omisoa pele kapa e sebelisoa mefuta e fetotsoeng holim'a metsi.
- Sebelisa dispersants (mohlala, BYK-190, TEGO Dispers 750W) ho ntlafatsa ho lekana le ho thibela ho senyeha ha mobu.
- Ho lumellana ha pH:
- Mekhoa ea acrylic e thehiloeng metsing hangata e na le pH ea 8-9; etsa bonnete ba hore AHP le ZB li lula li tsitsitse (qoba hydrolysis kapa ho bola).
- Ho Latela Melao:
- AHP e tlameha ho fihlela litlhoko tsa RoHS tse se nang halogen; ZB e lokela ho sebelisa maemo a tlase a litšila tsa tšepe e boima.
V. Litharollo tse ling kapa tse tlatsetsang
- Melamine Polyphosphate (MPP):E ka eketsa ho lieha ha lelakabe ha e kopantsoe le AHP (mohlala, 10% AHP + 5% MPP + 3% ZB).
- Lintho tse thibelang mollo oa Nano:ZB ea sehlopha sa nano (e ekelitsoe ho 1%~3%) kapa li-hydroxide tse habeli tse nang le mekhahlelo (LDH) bakeng sa litlamorao tse ntlafalitsoeng tsa thibelo.
VI. Kakaretso ea Litlhahiso
- Mokgwa wa ho qala:AHP 10%~15% + ZB 3%~5% (kakaretso 13%~20%), ebe o ntlafatsa.
- Mokhoa oa netefatso:Leka disampole tse nyane bakeng sa LOI le UL-94 ha o ntse o lekola thepa ea mechini.
