Litharollo tse thibelang malakabe bakeng sa thermoplastic elastomer TPE

Litharollo tse thibelang malakabe bakeng sa thermoplastic elastomer TPE

Ha o sebedisa aluminium hypophosphite (AHP) le melamine cyanurate (MCA) ho thermoplastic elastomers (TPE) ho fihlella tekanyo ya UL94 V0 ya ho thibela malakabe, ho bohlokwa ho nahana ka mokgwa wa ho thibela malakabe, ho tsamaellana ha thepa, le maemo a tshebetso. Ka tlase ke mokhoa o kgothalletswang:

1. Ho jarisoa ho Tloaelehileng Ha ho Sebelisoa ka Bonngoe

Aluminium Hypophosphite (AHP)

• Ho kenya: 15-25%
• Litšobotsi: E khothalletsa ho thehoa ha char, e loketse litsamaiso tse hlokang ts'ebetso e phahameng ea mechini, empa mocheso oa ts'ebetso o lokela ho laoloa (o khothaletsoa ≤240°C).

Melamine Cyanurate (MCA)

• Ho kenya: 25-35%
• Litšobotsi: E itšetlehile ka ho bola ha endothermic le ho qhibiliha ha khase; ho jara ka bongata ho ka fokotsa ho tenyetseha ha thepa.

2. Foromo e Khothaletsoang ea ho Kopanya ka Tšehetso e Kopanetsoeng

Karolelano ea ho Kopanya ea AHP le MCA

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

Melemo: Tšusumetso e kopanetsoeng e fokotsa mojaro o felletseng ha ka nako e ts'oanang e fokotsa ts'usumetso holim'a thepa ea mechini (mohlala, matla a ho thaepa, ho tenyetseha).

3. Lintlha tsa Bohlokoa tse Susumetsang

• Mofuta oa Thepa ea Motheo: Li-TPE tse thehiloeng ho SEBS hangata li bonolo ho li thibela ho tuka ha mollo ho feta tse thehiloeng ho SBS, e leng se lumellang hore ho be le mojaro o tlase hanyane oa tlatsetso.
• Botenya ba Sampole: Ho latela melao ya UL94 V0 ho tenyetseha ho botenya (1.6mm e thata ho feta 3.2mm), kahoo diforomo di lokela ho lokiswa ka ho ya ka maemo.
• Batšehetsi ba tšebelisano-'moho: Ho eketsa 2-5% nano-clay kapa talc ho ka ntlafatsa sebopeho sa char le ho fokotsa mojaro o thibelang malakabe.
• Mocheso oa ho SebetsaNetefatsa hore mocheso oa ts'ebetso o lula o le ka tlase ho lintlha tsa ho bola ha AHP (≤240°C) le MCA (≤300°C).

4. Mehato e Khothaletsoang ea Netefatso

• Teko ea Pele: Etsa liteko tse nyane ka AHP 12% + MCA 15% (kakaretso ea 27%).
• Teko ea Tshebetso: Lekola ho lieha ha lelakabe (ho chesa ho otlolohileng ha UL94), ho thatafala (Lebopong la A), matla a ho thapolla, le index ea phallo ea ho qhibiliha.
• Ntlafatso: Haeba ho rotha metsi, eketsa karolelano ea AHP (ho ntlafatsa ho chesa); haeba thepa ea mechini e le mpe, nahana ka ho eketsa li-plasticizer kapa ho fokotsa mojaro o felletseng.

5. Litlhokomelo

• Qoba ho kopanya le di-filler tse nang le asiti (mohlala, di-colorant tse itseng), kaha di ka sitisa AHP ho tsitsa.
• Haeba TPE e na le bongata bo boholo ba li-plasticizer tse thehiloeng oling, ho ka hlokahala hore ho eketsoe mojaro o thibelang malakabe (oli e ka fokotsa katleho ea ho thibela malakabe).

Ka ho kopanya ka tsela e utloahalang le ntlafatso ea liteko, ho latela melao ea UL94 V0 ho ka finyelloa ha ho ntse ho leka-lekana bokhoni ba ho sebetsa ba TPE le ts'ebetso ea mechini. Ho khothaletsoa tšebelisano-'moho le bafani ba litharollo tse etselitsoeng motho ka mong.
