Litharollo tse thibelang malakabe bakeng sa thermoplastic elastomer TPE

Litharollo tse thibelang malakabe bakeng sa thermoplastic elastomer TPE

Ha o sebelisa aluminium hypophosphite (AHP) le melamine cyanrate (MCA) ho thermoplastic elastomers (TPE) ho fihlela tekanyo e thibelang lelakabe la UL94 V0, ho bohlokoa ho nahana ka mochine o thibelang lelakabe, ho lumellana ha thepa, le maemo a ho sebetsa. Ka tlase ke mokhoa o khothaletsoang:

1. Tloaelehileng Loading Ha E sebelisoa ka bomong

Aluminium Hypophosphite (AHP)

• E beha: 15-25%
• Litšobotsi: E khothalletsa tlhahiso ea char, e loketseng mekhoa e hlokang ts'ebetso e phahameng ea mechine, empa mocheso oa ho sebetsa o lokela ho laoloa (ho khothaletsoa ≤240 ° C).

Melamine Cyanurate (MCA)

• E beha: 25-35%
• Litšobotsi: E itšetlehile ka ho bola ha endothermic le ho hlapolla ha khase; mojaro o phahameng o ka fokotsa ho tenyetseha ha lintho.

2. E khothalelitsoeng ea Synergistic Blending Foromo

Karolelano ea ho kopanya ea AHP le MCA

• AHP: 10-15%
• MCA: 10-20%
• Kakaretso ea thepa: 20-30%

Melemo: Phello ea Synergistic e fokotsa ho jara ka botlalo ha e ntse e fokotsa tšusumetso ho thepa ea mochini (mohlala, matla a ho tsitsa, elasticity).

3. Lintlha Tse ka Sehloohong Tse Susumetsang

• Mofuta oa Boitsebiso ba Motheo: Li-TPE tse thehiloeng ho SEBS hangata li bonolo ho chesoa ke lelakabe ho feta tse thehiloeng ho SBS, tse lumellang hore ho be le tlatsetso e tlase hanyane.
• Mohlala oa Botenya: UL94 V0 compliance ha e nahanele botenya (1.6mm e thata ho feta 3.2mm), kahoo libopeho li tlameha ho lokisoa ka nepo.
• Li-synergists: Ho eketsa 2-5% nano-clay kapa talc ho ka ntlafatsa sebopeho sa char le ho fokotsa ho kenya mollo o thibelang mollo.
• Mocheso oa ho sebetsa: Etsa bonnete ba hore mocheso oa ho sebetsa o lula o le ka tlas'a lintlha tsa ho senyeha ha AHP (≤240 ° C) le MCA (≤300 ° C).

4. Recommended Netefatsa Mehato

• Teko ea Pele: Etsa liteko tse nyenyane ka AHP 12% + MCA 15% (kakaretso ea 27%).
• Teko ea Ts'ebetso: Lekola ho lieha ha lelakabe (UL94 ho chesa ka holimo), ho thatafala (Lebōpo la A), matla a tsitsitseng, le ho qhibiliha ho phalla ha index.
• Ntlafatso: Haeba ho rotha ho etsahala, eketsa karolelano ea AHP (ho ntlafatsa charring); haeba thepa ea mochini e fokola, nahana ka ho eketsa li-plasticizers kapa ho fokotsa palo eohle ea thepa.

5. Litlhokomelo

• Qoba ho kopana le li-acidic fillers (mohlala, li-colorants tse itseng), kaha li ka hlokisa AHP botsitso.
• Haeba TPE e na le li-plasticizers tse ngata tse thehiloeng ka oli, ho ka 'na ha hlokahala hore ho be le lelakabe la retardant ho eketseha (oli e ka fokotsa ts'ebetso ea ho thibela mollo).

Ka ho kopanya ka mokhoa o utloahalang le ho ntlafatsa liteko, ho lumellana ha UL94 V0 ho ka finyelloa ha ho ntse ho leka-lekanya ts'ebetso ea TPE le ts'ebetso ea mochine. Ho khothaletsoa tšebelisano 'moho le barekisi ba retardant bakeng sa litharollo tse ikhethileng.
