Ibisobanuro bya V-0 Flame-Retardant PVC Thermoplastique Plastike

Kugirango ugere kuri V-0 ya flame retardancy (ukurikije ibipimo bya UL-94) muri plastiki ya PVC ya termoplastique, aluminium hypophosphite na acide ya boric ni bibiri bikunze gukoreshwa. Inzego zabo ziyongera zigomba kunozwa hashingiwe kubikorwa byihariye, uburyo bwo gutunganya, nibisabwa. Hano hari ibyifuzo hamwe nurwego:

1. Kwiyongera Urwego rwa Aluminium Hypophosphite

Aluminium hypophosphite ni fosifore ikora neza ya flame retardant ikwiranye nibikoresho bya PVC. Irabuza gutwikwa ikora fosifate ikingira kandi ikarekura gaze ya fosifori.

• Basabwe kongera urwego: 15-25 interuro(ibice ku bice ijana bya resin)
• Kuri PVC isanzwe, wongeyeho20 interuroya aluminium hypophosphite mubisanzwe igera kuri V-0 flame retardancy rating.
• Kubirinda umuriro mwinshi, dosiye irashobora kwiyongera, ariko ingaruka kumiterere yubukanishi igomba kwitabwaho.
• Icyitonderwa:
• Aluminium hypophosphite ikabije irashobora kugabanya imikorere yo gutunganya (urugero, ibintu bitagenda neza).
• Birasabwa guhuza hamwe nizindi retardants (urugero, aside boric, hydroxide ya aluminium) kugirango bigerweho.

2. Kwiyongera Urwego rwa Acide ya Boric

Acide ya Boric nigiciro gito cya flame retardant ikora cyane cyane binyuze mu kubora kwa endothermic no gushiraho ikirahure kimeze nkikirahure.

• Basabwe kongera urwego: 5-15 interuro
• Acide Boric isanzwe ikoreshwa nkumuriro wa kabiri wumuriro, kandi umubare mwinshi urashobora kwangiza imashini nogutunganya.
• Muri PVC, wongeyeho10 interuroya acide ya boric irashobora guhuza na aluminium hypophosphite kugirango yongere umuriro.
• Icyitonderwa:
• Acide ya Boric ni hygroscopique, kubika no gufata neza bigomba kwirinda kwinjiza amazi.
• Ingaruka ya flame-retardant igarukira iyo ikoreshejwe wenyine; isanzwe ihujwe nizindi retardants (urugero, hypophosphite ya aluminium, hydroxide ya aluminium).

3. Guhuza imbaraga za Aluminium Hypophosphite na Acide ya Boric

Kugirango ugere kuri V-0, aluminium hypophosphite na aside ya boric irashobora guhuzwa kugirango bigerweho. Hano hepfo haribisobanuro:

• Aluminium hypophosphite: 15-20 interuro
• Acide Boric: 5-10 interuro
• Ibindi byongeweho:
• Plastiseri (urugero, DOP): Nkuko bikenewe (byahinduwe hashingiwe kubisabwa bya PVC)
• Stabilisateur:2-5 interuro(urugero, imyunyu ngugu, calcium-zinc stabilisateur)
• Amavuta:0.5–1 interuro(urugero, aside stearic)

Urugero:

• PVC resin:100 interuro
• Aluminium hypophosphite:18 interuro
• Zinc borate:8 interuro
• Amashanyarazi (DOP):40 interuro
• Stabilisateur:3 interuro
• Amavuta:0.8 interuro

4. Kugerageza no Gukwirakwiza

Mubikorwa bifatika, intambwe zikurikira zirasabwa kugerageza no gukora neza:

1. Abapilote:Tegura igeragezwa rito rishingiye kumurongo.
2. Ikizamini cya UL-94:Kora ibizamini byo gutwika vertical kugirango usuzume urutonde rwa flame retardancy.
3. Ikizamini cyimikorere:Suzuma imiterere yubukanishi (urugero, imbaraga zingana, imbaraga zingaruka) hamwe nuburyo bwo gutunganya (urugero, gutembera, guhagarara neza).
4. Gukwirakwiza:Hindura urwego rwiyongereye rwa aluminium hypophosphite na acide ya boric cyangwa utangire izindi retardants (urugero, hydroxide ya aluminium, antimoni trioxide) kugirango urusheho kunoza imikorere.

5. Ibitekerezo by'ingenzi

• Ubushyuhe bwo gutunganya:Ubushyuhe bwo kubora bwa aluminium hypophosphite na aside ya boric ni hejuru cyane; menya neza ko ubushyuhe bwo gutunganya butarenga imipaka kugirango wirinde kwangirika.
• Gutatanya:Menya neza ko gukwirakwiza umuriro muri PVC kugirango wirinde ibibazo byibanze.
• Ingaruka ku bidukikije:Aluminium hypophosphite na aside ya boric byombi birinda ibidukikije byangiza ibidukikije, ariko guhuza nibindi byongeweho bigomba kugenzurwa.

6. Umwanzuro

Kugirango ugere kuri V-0 flame retardancy igipimo muri plastike ya PVC ya termoplastique, urwego rwiyongereyeho ni15-25 interuro ya aluminium hypophosphitena5-15 interuro ya aside ya boric. Gukoresha uburyo bwo gukoresha flame retardants birashobora kongera imikorere. Mu myitozo, optimizasiyo ishingiye kumikorere yihariye nibisabwa ni ngombwa, kandi ikizamini cya UL-94 kigomba gukorwa kugirango hamenyekane igipimo cy’umuriro.
